CANCELLED – Vortrag „Non-price product differentiation in charitable giving – Evidence from two randomized field experiments“

Manuel Grieder (UniDistance Suisse)

„Non-price product differentiation in charitable giving – Evidence from two randomized field experiments“

Joint work with Jan Schmitz

Abstract: Charities often ask for donations to one cause at a time, which limits how well appeals match diverse donor preferences. We study non-price product differentiation which is offering multiple giving options in a single appeal, as a strategy to better align with donor preferences and increase support for public goods. In partnership with the International Committee of the Red Cross (ICRC), we conducted two large-scale, pre-registered field experiments (N = 120,529 in 2023; N = 180,049 in 2024). Our non-price product differentiation treatments increased response rates by up to 16% and net revenues by up to 31% relative to single-cause treatments, with no evidence of crowding out in subsequent or repeated campaigns. A simple model of heterogeneous donor preferences over substitutable causes helps explain the results. Our findings indicate that non-price product differentiation within charities can be a new lever for increasing funding of public goods.

Vortrag: „A Democratic Dividend in Trade? Evidence from a Flexible Empirical Implementation“

Mario Larch (Universität Bayreuth)

„A Democratic Dividend in Trade? Evidence from a Flexible Empirical Implementation“

Joint work with Rodolphe Desbordes and Markus Eberhardt

Abstract: We extend the standard structural gravity model for bilateral trade flows to allow for the analysis of country-specific (monadic) binary variables. Our original difference-in-differences implementation is estimated at the country-pair level and accounts for selection into treatment, multilateral resistance, globalisation effects, and spatial dependence. This opens up the opportunity to study a wide array of trade determinants that the current literature has had to ignore in its adherence to the empirical restrictions of the pooled gravity model. We apply our methodology to explore the causal effect of democratic regime change on bilateral trade flows. We initially find average effects of 46% higher exports for countries after thirty years in democracy, but demonstrate that these effects are driven by the democratic dividend for income: the causal chain runs from democracy to economic prosperity to trade, and democracy appears to have a limited “direct” effect on trade flows.

Vortrag: „Working from Home and Consumption in Cities“

Oliver Falck (Ludwig Maximilian University of Munich)

„Working from Home and Consumption in Cities“

Co-authors: J.-V. Alipour, S. Krause, C. Krolage, S. Wichert

Abstract: We estimate the impact of the Covid-induced shift to working from home (WFH) on offline consumer spending within cities. The analysis builds on a postcode-level panel (2019–2023) of novel cellphone mobility and payment card transaction data for 50 German metropolitan areas (MAs). Identification uses local differences in the exposure to the WFH shock, measured by neighbourhoods’ WFH potential: the fraction of residents with a teleworkable job. Difference-in-differences estimates show that higher WFH potential leads to persistent declines in morning mobility and higher local spending within MAs. We estimate an elasticity of spending with respect to WFH-induced mobility changes of -3.7%, driven by large MAs. Unlike in the US, the WFH shock did not spur business turnover, urban outmigration, or a sustained shift to e-commerce in Germany. We conclude that WFH primarily reshapes urban consumption by reallocating where people spend time.

Vortrag: „In-sample calibration yields conformal calibration guarantees“

Johanna Ziegel (ETH Zürich)

„In-sample calibration yields conformal calibration guarantees“

Joint work with Sam Allen, Georgios Gavrilopoulos, Alexander Henzi, and Gian-Reto Kleger

Abstract: Conformal predictive systems allow forecasters to issue predictive distributions for real-valued future outcomes that have out-of-sample calibration guarantees. On a more abstract level, conformal prediction makes use of in-sample calibration guarantees to construct bands of predictions with out-of-sample guarantees under exchangeability. The calibration guarantees are typically that prediction intervals derived from the predictive distributions have the correct marginal coverage. We extend this line of reasoning to stronger notions of calibration that are common in statistical forecasting theory. We study the theoretical properties of the resulting new conformal predictive systems, and compare their performance in a simulation experiment and in two case studies on European temperature forecasts and on predictions for the length of patient stay in Swiss intensive care units. Both approaches are found to outperform existing conformal predictive systems, while conformal IDR additionally provides a natural method for quantifying epistemic uncertainty of the predictions.

Vortrag: „Warnings about Future Jumps: Properties of the Exponential Hawkes Model“

Cecilia Mancini (Università di Verona)

„Warnings about Future Jumps: Properties of the Exponential Hawkes Model“

Joint paper with Rachele Foschi and Francesca Lilla

Abstract: We analyze jump risks in financial asset prices modeled by Ito semimartingales with an exponential Hawkes process as the jump counter. First, using little information, we estimate the probability that an observed jump cluster is not yet exhausted. Second, we make explicit the conditional density of consecutive jump durations and prove that durations stochastically increase. Third, we provide bounds for jump probabilities in consecutive time intervals. Application to 5-minute US returns shows that cluster depletion probabilities strongly correlate with the expected yearly jump count, and improve forecasts of jumps and realized variance.

Vortrag: „Can a deductible kill? The effect of patient cost-sharing on health“

Martin Salm (Tilburg University)

„Can a deductible kill? The effect of patient cost-sharing on health“

(Joint paper with Padmaja Ayyagari and Eric Sargent)

Abstract: We study the effect of patient cost-sharing on healthcare utilization and health outcomes. Using administrative population level data from the Netherlands and a regression discontinuity design exploiting variation in the timings of emergency room admissions around the annual deductible reset, we examine how changes in the financial incentives influence the use of healthcare and the effect this has on various health outcomes. Patients with an emergency room admission immediately following the annual deductible reset immediately exceed the annual deductible and enjoy effectively free care for the remainder of the year. These patients consume 14% more healthcare in the year affected, an effect driven by increased visits to medical specialists, compared to patients who had a similar emergency room admission immediately before the deductible reset. Despite this substantial increase in utilization, we are unable to detect short or long-term improvements in health outcomes including mortality, subsequent heart attacks or strokes, chronic disease incidence, or subsequent emergency room admissions. These results are robust across income groups, age, between the predictably healthy and unhealthy, and remain consistent under various alternative specifications. We conclude that, in the Dutch context, a small annual deductible effectively constrains healthcare spending without measurable adverse effect on health, consistent with traditional models of moral hazard in health insurance.

Vortrag: „Adaptive estimation of parameter curves for locally stationary processes“

Rainer Dahlhaus (Heidelberg University and University of Freiburg)

„Adaptive estimation of parameter curves for locally stationary processes“

(joint work with Stefan Richter)

Abstract: In this talk we give a short introduction to locally stationary processes and explain some basic ideas and results. In more detail we then discuss adaptive estimation of parameter curves for locally stationary processes. We investigate different cross validation approaches and a method based on contrast minimization and derive asymptotic properties of both methods. The results are applicable for different statistics under a general setting of local stationarity including nonlinear processes. The properties of the bandwidth selection methods are investigated in several simulation studies. The results for adaptive estimation also include general results for locally stationary processes. For example a general Bernstein inequality is derived for such processes.

Vortrag: „Glimpse into the practical work of the Statistical Office of Germany: Editing and Imputation“

Katja-Verena Bürk (Statistical Office of Germany)

„Glimpse into the practical work of the Statistical Office of Germany: Editing and Imputation“

Abstract: The presentation offers an inside look at the practical work carried out by the Statistical Office of Germany, focusing on the Editing and Imputation phase within the Generic Statistical Business Process Model (GSBPM). Because survey data contain errors or missing values, editing and imputation are essential steps to ensure the accuracy, consistency, and reliability of official statistics. The presentation outlines the general framework and methodologies applied in imputation projects and discusses recent experimental initiatives—along with their challenges—exploring automated techniques for statistical data editing.

Vortrag: „The ‘Daylit City’: Bright Houses on Blind Streets“

Alexander Haupt (University of Freiburg, University of Plymouth, CESifo)

„The ‘Daylit City’: Bright Houses on Blind Streets“

(Co-author: Kristof Dascher)

Abstract: Le Corbusier envisioned the modern city as composed of bright houses set within open space. By constructing well-spaced neighbourhoods, today’s real-estate developers pursue the Corbusian ideal of light. This paper provides both an economic rationale for, and a critical welfare assessment of, the resulting daylit city. It argues that modern block developers build low-density residential areas inefficiently close to the city centre, thereby driving rents above, and population below, the level found in an efficiently designed city. As their designs perforate the streetfronts, they undermine Jane Jacob’s principle of ‘eyes on the street’, diminishing urban vitality and safety. A fine-streetfront mandate can enhance efficiency, while simple property taxes produce mixed outcomes.

Vortrag: „Estimating large-scale nonlinear macroeconomic models using the ensemble transform Kalman filter“

Otilia Boldea (Tilburg University)

„Estimating large-scale nonlinear macroeconomic models using the ensemble transform Kalman filter“

(Co-authors: Amir Alipoor and Eva Janssens)

Abstract: This paper shows how to estimate large-scale nonlinear Dynamic Stochastic General Equilibrium (DSGE) models using the Ensemble Transform Kalman Filter (ETKF). Estimating large-scale DSGE models with many state variables, such as multi-sector and multi-country models or those with numerous shocks and real and nominal frictions, presents significant computational challenges. Failing to account for nonlinearities leads to inconsistent parameter estimates. However, standard nonlinear filtering methods become infeasible in high-dimensional settings due to the large number of particles required in particle filtering or the computational burden of tensor-product-based discretization methods. This paper demonstrates that the ETKF, combined with data augmentation, provides a computationally efficient and accurate alternative. We illustrate this through a simulation study estimating a multi-country DSGE model and an empirical application that quantifies the importance of nonlinearities in estimating the role of sectoral shocks in driving aggregate fluctuations within a multi-sector model. For standard estimates of elasticities of substitution between goods in both demand and production, we find that sectoral shocks contribute approximately 36% more to aggregate fluctuations in the nonlinear economy compared to the linear economy.

Vortrag: „Covariate Balancing and the Equivalence of Weighting and Doubly Robust Estimators of Average Treatment Effects“

Derya Uysal (LMU Munich)

„Covariate Balancing and the Equivalence of Weighting and Doubly Robust Estimators of Average Treatment Effects“

(Co-authors: Tymon Słoczyński, Jeffrey M. Wooldridge)

Abstract: How should researchers adjust for covariates? We show that if the propensity score is estimated using a specific covariate balancing approach, inverse probability weighting (IPW), augmented inverse probability weighting (AIPW), and inverse probability weighted regression adjustment (IPWRA) estimators are numerically equivalent for the average treatment effect (ATE), and likewise for the average treatment effect on the treated (ATT). The resulting weights are inherently normalized, making normalized and unnormalized IPW and AIPW identical. We discuss implications for instrumental variables and difference-in-differences estimators and illustrate with two applications how these numerical equivalences simplify analysis and interpretation.

Vortrag: „Civic Engagement: Why Volunteer?“

Femida Handy (University of Pennsylvania)

„Civic Engagement: Why Volunteer?“

Abstract: Research on civic engagement demonstrates that individuals participate for reasons that extend well beyond simple altruism. While traditional perspectives emphasize value-based motivations, such as helping others and building community, recent scholarship underscores a benefit-cost framework, where both individuals and organizations weigh the tangible and intangible gains against resource investments. Volunteers often trade time and effort for psychological growth, social connection, and improved well-being, while organizations balance increased capacity and legitimacy against coordination costs. Complementary findings on the good-looking giver effect reveal that prosocial behavior also intersects with social perception: attractive individuals are more likely to engage in giving, and volunteering itself is associated with enhanced social capital and attractiveness. Beyond volunteering, civic behaviors such as voting have been linked to health outcomes, with evidence that older adults who vote face lower mortality risk over time. Together, these strands of research suggest that prosocial engagement, whether through volunteering or civic participation, is driven by a combination of altruistic intentions, personal and organizational benefits, and social rewards, while also yielding measurable health and longevity advantages. Thus, people volunteer not only to help others, but also to reinforce identity, gain personal value, and sustain community and individual well-being across the life course.

Vortrag „Did they live happily ever after? Moral foundation narratives in folklore“

Nadia von Jacobi (University of Trento)

Did they live happily ever after? Moral foundation narratives in folklore

(Co-authors: M. Khesali, S.Voigt)

Abstract: It is often maintained that most values, norms and moral systems are largely time invariant but empirical evidence supporting that claim has been virtually non-existent. This study is a first step to change that. Since folktales, such as legends and fairy tales, are often transmitted virtually unchanged from generation to generation, we rely on them to extract information about the moral foundations held dear by different societies in the past. This study is the first to offer a comprehensive cross-country database regarding moral foundations. On the basis of 17,801 folktales from 179 countries, we introduce the Historical Moral Foundation (HistoMoF) dataset and show that moral foundations extrapolated from past folklore are rich material for identifying both moral universals but also significant differences across the globe. We test some of our variables elicited from past folklore and find they are good predictors for civil conflict that occurred a century later. We find that societies in which past folklore has discouraged subversion against authority, have experienced less civil conflict in the period 1945 – 1999, about a century later. This is but one example among many possible ones in which the Historical Moral Foundation dataset promises new insights.

Vortrag „A Theory of Digital Ecosystems“

Mats Köster (Central European University)

A Theory of Digital Ecosystems

(Co-authors: P. Heidhues, B. Kőszegi)

Abstract:

We develop a theory of digital ecosystems built on the premise that a multi-market firm can steer users it has in one market toward its products in other markets. Due to this “cross-market leverage,” a leader in an “access-point” market (where users begin their online journeys) derives a high value from offering services in connected markets (where users continue their journeys), and can thus make profitable takeovers. Indeed, because the firm has the outside option of acquiring, and steering users toward, its target’s competitor, it can take over the target at a discount. In contrast, other firms have no or smaller incentives for takeovers, explaining why ecosystems grow out of market leaders at access points. Conversely, cross-market leverage also implies that once an ecosystem has grown, it has an increased value of controlling access points, so it may go to great lengths to dominate these markets.

Our theory suggests that ecosystems have mixed implications for consumer welfare. Under plausible assumptions, a to-be ecosystem takes over market leaders, and this consolidation of good services across markets benefits consumers in the short run. But an ecosystem’s takeovers and dominance of access points lower incentives for entry and innovation, and lower the efficiency of access-point markets with superior alternatives. Hence, the long-run welfare implications of ecosystems are often negative.

Unpacking the Black Box of ICT: Firm Organization and Worker Outcomes

(Co-authors: P. Brewing, C. Steinwender, M. Antoni)

Abstract: Information and communication technologies (ICT) are widely recognized as a driver of firm growth, yet the underlying mechanisms remain unclear. This paper examines how firms benefit from broadband access through cloud-based software services such as enterprise resource planning (ERP) systems, which systematically collect, store, and disseminate data within firms in real time. We exploit a technology upgrade of pre-existing cable TV networks in Germany between 2009 and 2016 as a source of exogenous variation in cloud access. Linking firm-level ICT usage data with employer-employee matched data, we find that cloud access reduces employment while increasing sales and labor productivity. The decline in employment is concentrated among medium- and high-skilled workers, and is particularly pronounced in accounting. The complexity of tasks increases. At the same time, ERP adoption increases, suggesting that ERP substitutes for accounting employees while increasing the autonomy of production workers.

Vortrag: „Dual Pricing in a Model of Sales“

Anton Sobolev (University of Mannheim)

Dual Pricing in a Model of Sales

(Co-authors: N. Schutz)

Abstract: We study the competitive effects of dual pricing, a vertical restraint that involves charging a distributor a different price for units intended to be resold online than for units intended to be resold offline. We develop a model in which a manufacturer contracts with hybrid retailers, which sell the manufacturer’s product both in their brick-and-mortar stores and through an online channel. We find that dual pricing allows the manufacturer to induce the industry monopoly outcome whereas uniform pricing does not. Yet, dual pricing does not necessarily harm consumers or society at large, as the market outcome is distorted by market power regardless of whether dual or uniform pricing is used. Indeed, we find that consumer surplus and aggregate surplus tend to be higher under dual pricing if the online market is small, if the search costs faced by offline consumers are high, and if the pass-through rate of cost increases is high.

Festvortrag „Die ersten Monate unter Trump – Konsequenzen für Europa, für Deutschland und die Welt“

Dr. Wolfgang Merz

„Die ersten Monate unter Trump – Konsequenzen für Europa, für Deutschland und die Welt“

Abstract: Der seit Januar erneut amtierende US-Präsident Trump war extrem aktiv an verschiedenen Fronten. Vieles kam so, wie er es angekündigt hat, allerdings gab es auch herbe Überraschungen.

Für Europa war zunächst beunruhigend, dass die USA eine skeptische Haltung gegenüber der Ukraine einnahm und auch in Frage stelle, ob die USA künftig noch für die Sicherheit Europas garantieren würde. Konsequenterweise haben die europäischen Länder erst im kleineren Kreis unter Beteiligung von UK und dann auch auf der Ebene des Europäischen Rates darauf verständigt, künftig an einer neuen europäischen Sicherheitsarchitektur zu arbeiten. Auch wurde der Ukraine koordiniert ihre Unterstützung zugesichert.

In Deutschland hat das Agieren von Trump die Inhalte der Koalitionsvereinbarung der neuen Regierung stark geprägt. Entscheidend dabei ist insbesondere der Wille, wesentlich mehr Ressourcen für die nationale Verteidigung zur Verfügung zu stellen. Gleichzeitig fühlt sich eine neue deutsche Regierung wesentlich stärker angehalten, europäischen Prozessen mehr Dynamik zu verleihen und damit auch Europa zu stärken

Global hat die US-Ankündigung von zusätzlichen Zöllen für nahezu alle Länder auf der Welt für ziemliche Irritationen gesorgt. Ein positiver Effekt für die US Wirtschaft ist derzeit nicht erkennbar, da man Einbrüche an der Börse erlebte und das Risiko einer Inflationierung in der US-Wirtschaft besteht. Die bisherigen „deals“ mit einzelnen Ländern können nicht überzeugen, da etwa das Abkommen mit UK durchaus den britischen Interessen nahekommt.

Fazit: Trump hat durch einen vielfältigen Aktionismus für einige Unruhe gesorgt, zum Teil hat er aber genau das Gegenteil seiner Absichten bewirkt. Europa wird nicht geschwächt, sondern möchte sich stärken, auch durch weitere Integrationsschritte im Verteidigungsbereich. UK nähert sich wieder der EU an. Deutschland emanzipiert sich schmerzhaft von den USA und stärkt Europa. Global kann die Zollpolitik sich als Schuss nach hinten erweisen. Beim Ukraine-Krieg wird auch klar, dass man eben nicht in zwei Tagen einen „deal“ mit Putin hinbekommt. Die Welt ordnet sich nach solchen „Generalangriffen“ neu und neue strategische Bündnisse zwischen Europa, China, Indien, Australien, Kanada und Südafrika wären für die USA nicht von Vorteil. Auch haben jüngste Wahlen in Kanada und Australien gezeigt, dass gerade die Parteien, die eher Trump-skeptisch sind, gewinnen. Dies müsste der Trump Regierung an sich zu denken geben.

Vortrag: „Norms of Corruption in Politicians’ Malfeasance“

Anke Kessler (Simon Fraser University)

Norms of Corruption in Politicians’ Malfeasance

(Co-authors: G. Bobonis, X. Zhao)

Abstract: To what extent can anti-corruption measures serve to limit patronage and corrupt networks effectively and sustainably in clientelist societies with a prevailing norm of corruption? We develop a political agency model in which officeholders are motivated to reduce rent seeking behavior through re-election incentives operating via elections and audits (formal institutions), but also through reputational or self-image concerns that are influenced by the prevailing norm on corruption in their peer group (informal institutions). We show that, while the formal institutions of audits and elections have the desired direct effect of reducing corruption, they also affect social rules of conduct, which can have unintended consequences. In particular, we show that in clientelist societies with high levels of corruption, social image concerns work in opposition to formal incentives provided by anti-corruption efforts. Applying the theory to data from Puerto Rico’s anti-corruption municipal audits program, we find evidence consistent with the idea that anti-corruption measures are less effective due to social spillovers.

Vortrag: „Sequencing Bilateral Negotiations with Externalities“

Markus Reisinger (Frankfurt School of Finance & Management)

Sequencing Bilateral Negotiations with Externalities

(Co-authors: J. Münster)

Abstract: In most bargaining situations with multiple parties, the negotiation sequence is crucial for the efficiency of outcomes and the parties‘ success. However, the driving forces behind the socially and privately optimal sequences are poorly understood. To study these issues, we consider a general framework of bilateral negotiations between a principal and two agents with bargaining externalities. We show that the agents‘ bargaining strengths are essential for the determination of the sequence. The surplus is highest if the principal negotiates with the stronger agent first, regardless of externalities being positive or negative. The principal always chooses the efficient sequence if externalities are negative. Instead, if externalities are positive, the principal often prefers to negotiate with the weaker agent first. We show that our results extend to a general number of agents, demonstrate that the sequence can be non-monotonic in the externalities, and provide conditions for simultaneous negotiations to be optimal.

Vortrag: „Kill Two Birds with One Stone? Environmental Policy Design with Multiple Targets in the Swedish Car Market“

Cristian Huse (University of Oldenburg)

„Kill Two Birds with One Stone? Environmental Policy Design with Multiple Targets in the Swedish Car Market“

(Co-author: C. Lucinda)

Abstract: We evaluated environmental policies, specifically rebates like the Swedish Green Car Rebate (GCR), intended to meet EU CO2 and Renewable Fuel Standard (RFS) targets, using a structural model of the Swedish new vehicle market. Our simulations indicate that achieving both targets is infeasible through these rebates alone, even at high amounts. This infeasibility arises from both supply and demand factors. On the supply side, few low-emission models were available during the period studied. On the demand side, additional individual consumer data we collected revealed strong purchasing inertia (state dependence) related to vehicle size, brand, and specific models. Thus, meeting the twin targets appears unrealistic without a combination of: manufacturers introducing low-emission versions of popular models, a change in consumer preferences towards smaller vehicles, or significant technological advances like widespread electrification.

Vortrag: „Through stormy seas: how fragile is liquidity across asset classes and time?“ & „Decentralised dealers? Examining liquidity provision in Decentralised Exchanges“

Matteo Aquilina (Bank for International Settlements)

„Through stormy seas: how fragile is liquidity across asset classes and time?“ & „Decentralised dealers? Examining liquidity provision in Decentralised Exchanges“

Abstract Topic 1: Market liquidity across asset classes has considerably increased in recent decades. Our study of stocks, foreign exchange (FX), and government bonds in the US, Europe, and Japan—using 25 years of high-frequency data—reveals a significant decline in both the average and standard deviation of bid-ask spreads across all asset classes. However, we also observe an increase in its skewness and kurtosis in equity and bond markets, indicating more frequent episodes of illiquidity. In contrast, FX markets do not show a significant increase in the higher moments of the distribution of bid-ask spreads. We identify structural breaks in the time series of spread distributions across regions and asset classes, associate these breaks with macroeconomic shocks and changing market conditions, and quantify the cost of this fragility to investors.

Abstract Topic 2: Decentralised exchanges allow participants to buy and sell assets without the need for intermediaries, in theory democratising liquidity provision. However, using data from the largest decentralised exchange, we show that liquidity provision – rather than being the purview of a diffused set of market participants – is instead confined predominantly to a small group of sophisticated ones. These participants submit orders that mimic bids and asks and are able to extract significantly higher profits (both in absolute and relative terms) compared to their unsophisticated counterparts. They also exhibit considerable skill, extracting higher profits during periods of high volatility by capturing a higher share of trading without incurring additional adverse selection.

Abstract: This paper introduces a flexible framework for the estimation of the conditional tail index of heavy tailed distributions. In this framework, the tail index is computed from an auxiliary linear regression model that facilitates estimation and inference based on established econometric methods, such as ordinary least squares (OLS), least absolute deviations, or M-estimation. We show theoretically and via simulations that OLS provides interesting results. Our Monte Carlo results highlight the adequate finite sample properties of the OLS tail index estimator computed from the proposed new framework and contrast its behavior to that of tail index estimates obtained by maximum likelihood estimation of exponential regression models, which is one of the approaches currently in use in the literature. An empirical analysis of the impact of determinants of the conditional left- and right-tail indexes of commodities’ return distributions highlights the empirical relevance of our proposed approach. The novel framework’s flexibility allows for extensions and generalizations in various directions, empowering researchers and practitioners to straightforwardly explore a wide range of research questions.

Vortrag: „On the numerical approximation of minimax regret rules via fictitious play“

Patrik Guggenberger (Penn State University)

(joint work with Jiaqi Huang)

„On the numerical approximation of minimax regret rules via fictitious play“

Abstract: Given the lack of analytical solutions for minimax regret treatment rules in most scenarios of empirical interest, finding numerical approximations is of key interest. To do so, in this paper, we suggest discretizing the action space of nature and then using an algorithm based on Robinson’s (1951) pioneering work on iterative solutions for two-person zero sum games with finite action space. This approach is known in the game theory literature as fictitious play and can be shown to converge to a minimax rule, see Fudenberg and Tirole (1998). As a key application we consider a policymaker who has to choose between two treatments after observing a dataset with potentially unequal sample sizes per treatment. To dramatically increase computation time we leverage the general algorithm with theoretical insights about certain symmetry conditions that can be imposed on the treatment rules.

Vortrag: „Nowcasting consumer price inflation using high-frequency scanner data: evidence from Germany“

Kai Carstensen (Kiel University)

(joint work with Günter W. Beck, Jan-Oliver Menz, Richard Schnorrenberger, and Elisabeth Wieland)

„Nowcasting consumer price inflation using high-frequency scanner data: evidence from Germany“

Abstract: We study how millions of granular and weekly household scanner data combined with ma- chine learning can help to improve the real-time nowcast of German inflation. Our nowcast- ing exercise targets three hierarchy levels of inflation: individual products, product groups, and headline inflation. At the individual product level, we construct a large set of weekly scanner-based price indices that closely match their official counterparts, such as butter and coffee beans. Within a mixed-frequency setup, these indices significantly improve inflation nowcasts already after the first seven days of a month. For nowcasting product groups such as processed and unprocessed food, we apply shrinkage estimators to exploit the large set of scanner-based price indices, resulting in substantial predictive gains over autoregressive time series models. Finally, by adding high-frequency information on energy and travel services, we construct competitive nowcasting models for headline inflation that are on par with, or even outperform, survey-based inflation expectations.

Vortrag: „Domestic Violence Court Rulings in the Shadow of Terrorism“

Claude Berrebi (The Hebrew University of Jerusalem)

(joint work with Yaacov Ben-Moshe)

„Domestic Violence Court Rulings in the Shadow of Terrorism“

Abstract: In the context of the Israeli-Palestinian conflict and Israel’s court system our study focuses on the effect of terrorism on judges‘ decisions with respect to their tendencies to grant the issuing of restraining orders to immediate family members, such as domestic partners and spouses. Our findings suggest that the effect of terrorism on the decisions of judges the day following a terrorist attack is in the order of a 10% -11% increase in the approval’s likelihood, holding everything else constant. For the overall population, this effect weakens as time goes by from the day of the attack and statistically disappears within a week. Interestingly, though not necessarily surprising, we find that the effect increases three- fold when the defendant (i.e. respondents) accused of domestic violence is an Arab male. The tendency to issue restraining orders to Arab respondents increases by about 32% during times of terror campaigns relative to calmer (routine) periods. More generally we show that the probability of issuing a restraining order, following a terrorist attack when the respondent’s ethnicity differs from the judge’s ethnic group, increases by 20% relative to the situation in which the respondent and the judge are members of the same ethnic group. Robustness tests and placebo runs are used to reinforce the likelihood that our findings represent a causal effect of terrorism on judges’ decisions.

Vortrag: „The Value of Decision Rights within the Household: Experimental Evidence from Colombia“

Marcela Ibanez (University of Göttingen)

(joint work with Natalia Cantet, Tatiana Orozco-Garcia, and Gerhard Riener)

„The Value of Decision Rights within the Household: Experimental Evidence from Colombia“

Abstract: In this study, we examine the intra-household decision-making process and investigate individuals’ motivations to demand agency by contesting their partner’s decision right over a clearly defined cause. Considering that agency has not only an instrumental but also an intrinsic value, we design an economic experiment that allows us to disentangle three potential motives behind the value of agency: a desire for power, a demand for freedom, and a desire for autonomy. We find that agency has an intrinsic value and that men and women are willing to buy decision rights even though the choices of the partners would lead to identical outcomes. However, there are marked gender differences. When interacting with the spouse, men have higher willingness to pay for decision rights than women. This is associated with a preference for freedom. No such motivation is observed when men interact with a stranger. Our results suggest that providing women with access to income generation opportunities will not necessarily translate into higher levels of decision-making within the household. In particular, this finding indicates the need to protect women against the demands from the spouse.

Vortrag: „Greenhouse Gas Mitigation and Price-Driven Growth in a Solow-Swan Economy with an Environmental Limit“

Michael C. Burda (Humboldt-Universität zu Berlin)

(joint work with Leopold Zessner-Spitzenberg)

„Greenhouse Gas Mitigation and Price-Driven Growth in a Solow-Swan Economy with an Environmental Limit“

Abstract: The existence of an environmental limit in the Solow-Swan economy changes the nature of economic growth, but does not preclude it. When atmospheric greenhouse gases reach a predetermined absolute threshold, further growth requires a permanently expanding, resource-intensive mitigation effort. If the rate of technical progress in mitigation is too low, it becomes the effective constraint on economic growth. Yet growth in both quantities and relative prices remains a robust feature of this class of economies. It also characterizes the social planner’s optimum that anticipates the costs of reaching the environmental limit abruptly.

Vortrag: „An IVX Approach to Detecting the Predictive Power of Imperfect Predictors with smoothly Varying Components“

Matei Demetrescu (TU Dortmund University)

(joint work with Mehdi Hosseinkouchak)

„An IVX Approach to Detecting the Predictive Power of Imperfect Predictors with smoothly Varying Components“

Abstract: The typical predictor variable in predictive regressions for stock returns exhibits high persistence, which leads to nonstandard limiting distributions of the least-squares estimator and the associated t statistic. While there are several methods to deal with the issue of nonstandard distributions, high predictor persistence also opens the door to spurious regression findings induced by the use of imperfect predictors, i.e. when the predictors do not perfectly span the conditional mean of the stock returns. We robustify IVX predictive regression (Kostakis et al., 2015, Review of Financial Studies 28, 1506–1553) to the presence of smoothly varying components of the predictive system. In specific, we resort to a filter which exploits the slow variation to identify the mean component of the stock returns unaccounted for by the imperfect predictors. The limiting distribution of the resulting modified IVX t statistic is derived under sequences of local alternatives, and a wild bootstrap implementation improving the finite-sample behavior is provided. Compared to standard IVX predictive regression, there is a price to pay for such robustness in terms of power; at the same time, the IVX statistic without adjustment consistently rejects the false null of no predictability in the presence of imperfect predictors.

Vortrag: „Consumption Partial Insurance in the Presence of Tail Income Risk“

Alexandros Theloudis (Tilburg University)

(joint work with Anisha Ghosh)

„Consumption Partial Insurance in the Presence of Tail Income Risk“

Abstract: We measure the extent of consumption insurance to income shocks accounting for high-order moments of the income distribution. We derive a nonlinear consumption function, in which the extent of insurance varies with the sign and magnitude of income shocks. Using PSID data, we estimate an asymmetric pass-through of bad versus good permanent shocks – 17% of a 3σ negative shock transmits to consumption compared to 9% of an equal-sized positive shock – and the pass-through increases as the shock worsens. We find similar patterns for transitory shocks among the least wealthy. Households are willing to sacrifice more than 1/8 of lifetime consumption to eliminate tail income risk. Our results are consistent with surveys of consumption responses to hypothetical events and suggest that tail risk matters substantially for consumption.

Vortrag: „Modeling and Forecasting the Long Memory of Cyclical Trends in Paleoclimate Data“

Philipp Sibbertsen (Leibniz University Hannover)

(joint work with Tomas del Barrio Castro and Alvaro Escribano)

„Modeling and Forecasting the Long Memory of Cyclical Trends in Paleoclimate Data“

Abstract: This paper identifies and estimates the relevant cycles in paleoclimate data of earth temperature, ice volume and CO2 . Cyclical cointegration analysis is used to connect these cycles to the earth eccentricity and obliquity and to see that the earth surface temperature and ice volume are closely connected. These findings are used to build a forecasting model including the cyclical component as well as the relevant earth and climate variables which outperforms models ignoring the cyclical behaviour of the data. Especially the turning points can be predicted accurately using the proposed approach. Out of sample forecasts for the turning points of earth temperature, ice volume and CO2 are derived.

Vortrag: „Inattentiveness and the Taylor Principle“

Alexander Meyer-Gohde (Goethe University Frankfurt)

(joint with Mary Tzaawa-Krenzler)

„Inattentiveness and the Taylor Principle“

Abstract: We present determinacy bounds on monetary policy in three models of inatten- tiveness – sticky information, imperfect common knowledge, and arbitrary finite inatten- tiveness. We find that these bounds are identical across these models as they all share a common vertical long run Phillips curve. The resulting bounds are more conservative than in the standard Calvo sticky price New Keynesian model. Specifically, the Taylor principle is now necessary directly – no amount of output targeting can substitute for the monetary authority’s concern for inflation. These determinacy bounds are obtained by appealing to frequency domain and forecasting/prediction innovation techniques that themselves provide novel interpretations of the Phillips curves.

Vortrag: „Two-Sided Sorting and Spatial Inequality in Cities“

Matthias Hoelzlein (University of Notre Dame)

„Two-Sided Sorting and Spatial Inequality in Cities“

Abstract: This paper studies how two-sided sorting of firms and households drives inequality within cities. I develop a quantitative model that features skill heterogeneity, non-homothetic de- mand for local consumption sectors and varying skill intensity in production. As a neighbor- hood become more skilled, firms catering to the rich and employing skilled workers enter, further reinforcing skill sorting. To validate the model’s mechanisms, I replicate the estimated impact of Empowerment Zones on household and firm sorting in model counterfactuals. I apply the model to explore how alternative policies employing two-sided sorting as a tool reach targeted populations more effectively and direct neighborhood change.

Vortrag: „Pricing in Transition and Physical Risks: Carbon Premiums and Stranded Assets“

Christoph Hambel (Tilburg University)

(gemeinsam mit Rick van der Ploeg)

„Pricing in Transition and Physical Risks: Carbon Premiums and Stranded Assets“

Abstract: We analyze asset pricing and climate policy in the face of transition and physical risks using a global two-sector, DSGE model of climate and the economy. Physical risks consist of temperature-related risks of recurring climate-related disasters and the risks of irreversible climate tipping. Transition risks consist of changes in policy regime with three states (no, modest, or aggressive carbon pricing) and of technological breakthroughs in negative emissions technologies. Both these type of risks affect the carbon price, the risk-free rate, and the risk premiums of green and brown assets. We find that carbon premiums result from policy transition risks, especially if the economy is still quite carbon-intensive and close to the temperature cap, and give a signal to accelerate the green transition. We also show that transition risks trigger asset stranding. The risks of asset stranding are also priced in and lead to more sizable carbon risk premiums and a more rapid green transition.

Vortrag: „Inflation and Wage Expectations of Firms and Employees“

Sebastian Link (ifo Institut)

(gemeinsam mit Lukas Buchheim und Sascha Möhrle)

„Inflation and Wage Expectations of Firms and Employees“

Abstract: We study the link between expected inflation and wages using novel panel data from German firms and employees. We find that pass-through-the percentage point change in wage growth given a one percentage point change in expected inflation-is small: 0.11-0.17 for firms and 0.03-0.07 for employees. Utilizing variation in the coverage length of collective agreements, we estimate that pass-through at the intensive margin is 1.4-2 times larger than average pass-through, highlighting the importance of wage rigidities for pass-through. Pass-through also rises with the bargaining power of employees. At the extensive margin, expected inflation has little effect on additional wage negotiations.

Vortrag

Matthias Haslberger (Universität St. Gallen)

„Winners and Losers of the Generative AI Revolution“

Abstract: Generative artificial intelligence is beginning to transform the world of work, reconfiguring economic and political inequalities in the process. An emergent scientific consensus holds that generative AI compresses performance differentials between more and less able workers. We argue that this view, which is based on experiments with a narrow range of occupations, may not scale to the labour market at large, where AI largely reproduces existing inequalities. Meanwhile, little is known about how first-hand experience with AI use shapes people’s attitudes towards the technology and potential policy responses.

We conducted a pre-registered online experiment with a representative sample of 1,041 working-age adults from the UK. We asked respondents to complete a set of text-based tasks of varying complexity and ambiguity while randomly assigning them to treatments that encouraged or discouraged the use of ChatGPT. We measured their response time and answer quality as an indicator of productivity and surveyed their attitudes towards AI and compensatory social policies.

We find that exposure to ChatGPT led to significant reductions in time spent accompanied by substantial improvements in answer quality. The productivity increases were greatest in more complex and less ambiguous tasks. The treatment did not affect inequalities in performance along gender, educational, or occupational lines. However, older workers benefited less than younger workers from ChatGPT exposure. Thus, while AI appears to compress the returns to occupation-specific skills, existing inequalities between groups were largely replicated.

While many respondents were concerned about the impact of AI on society and their own lives, respondents in the treatment group generally had a more positive attitude towards the technology. However, we found no effect of AI exposure on social policy preferences or political leanings. Overall, a cautious attitude prevailed: mindful of both risks and benefits, respondents expressed widespread support for government regulation of AI. A quantitative analysis of open text answers affirms these findings.

Our survey enables a first big-picture investigation of the society-wide impact of generative AI on economic and political inequalities. Our study shows major aggregate effects on productivity, but relatively minor consequences for between-group inequalities due to AI itself. Against a baseline of high scepticism, exposure to AI leads to more positive attitudes towards the technology without affecting social policy preferences. Thus, our study provides early evidence that AI will not be the great equaliser some are hoping for.

Vortrag

Dominik Beckers (FinEst Centre for Smart Cities, Tallinn University of Technology)

„Governing Smart City Transitions: From Theory to Practice“

Abstract: By 2050, 68% of the world’s population is expected to live in urban areas, leading to more and more resources and processes being concentrated in cities. Their ever-growing importance, however, is accompanied with increasingly complex economic, environmental and social issues. Digital technologies can help address these challenges. Yet, research on the governance of smart city transitions remains undertheorized and is incapable of guiding city officials and other stakeholders. In my presentation, I will provide theoretical and practical answers that my research and research group have generated in response to these problems. On the theoretical side, I will introduce a comprehensive smart city governance framework based on a systematic literature review as well as how smart city research can learn from innovation management studies – a more mature research field – to overcome currently existing theoretical gaps. On the practical side, I will present the findings of a major study conducted for UN Habitat and CAF that investigates the smart city governance practices of more than 250 cities worldwide.

Der Vortrag findet am Donnerstag, den 27. April2023, von 14:00-15:30 s.t. im Seminarraum 01012 (Rempartstraße 16, 1. OG) statt. Es kann auch online teilgenommen werden. Bitte kontaktieren Sie elmar.offenwanger@vwl.uni-freiburg.de oder  info@fww-ev.de für die Zugangsdaten.

„Minimum Wage Pass-through to Wholesale and Retail Prices: Evidence from the Washington State Cannabis Industry“

Abstract: A growing empirical literature finds that firms pass the cost of minimum wage hikes onto consumers via retail prices. Yet, little is known about minimum wage effects on wholesale prices and whether retailers face a wholesale cost shock in addition to the labor cost shock. I exploit the unique market structure of Washington state’s legal recreational cannabis industry to investigate minimum wage pass-through to wholesale and retail prices. In a dynamic difference-in-differences framework, I utilize scanner data on $6 billion of transactions across the supply chain and leverage geographic variation in firms‘ minimum wage exposure across six minimum wage hikes between 2018 and 2021. When ignoring wholesale cost effects, I find retail pass-through rates consistent with existing literature—yet retail pass-through rates double once wholesale cost effects are accounted for. Retail markups do not adjust to wholesale pass-through, indicating a full transmission of wholesale cost shocks to retail prices. The results suggest that previous research may underestimate the impact of minimum wage increases on retail prices. This paper highlights the importance of analyzing the entire supply chain when evaluating the product market effects of minimum wage hikes.

Der Vortrag findet am Donnerstag, den 09. Februar 2023, von 14:00-15:30 s.t. im Seminarraum 01012 (Rempartstraße 16, 1. OG) statt. Es kann auch online teilgenommen werden. Bitte kontaktieren Sie elmar.offenwanger@vwl.uni-freiburg.de oder  info@fww-ev.de für die Zugangsdaten.

„The breakup of the Bell System and its Impact on Innovation“

Abstract: We analyze the effects of the 1984 breakup of the Bell System on the rate, diversity, and direction of US innovation. In the antitrust case leading to the breakup, AT&T, the holding company of the Bell System, was accused of using exclusionary practices against competitors. The breakup was intended to end these practices. After the breakup, the scale and diversity of telecommunications innovation increased. Total patenting by US inventors related to telecommunications increased by 19%, driven by companies unrelated to the Bell System. Patenting by Bell’s successor companies decreased, but not the number of top inventions.

“Border Walls and Terrorism”

Abstract: Are physical walls between countries effective at reducing terrorist attacks? Despite their prohibitive cost and political divisiveness, walls between contiguous countries have recently proliferated as extreme forms of border control, especially following 9/11 and the 2015 refugee crisis. Yet, their effectiveness at mitigating the alleged migration-terrorism nexus is largely unknown. We use the most up-to-date dataset on walls between adjacent countries worldwide (1920-2018), and rely on the staggered construction of walls across some country-dyads over time as an identification strategy. Our findings demonstrate that border walls are a very poor defense against transnational terrorism. Not only do they fail to curb terrorist attacks but, under specific conditions, walls may actually backfire, so that attacks substantially increase after the erection of a wall. Our difference-in-differences analyses and case studies of the walls between Saudi Arabia-Iraq (2014) and Israel-Egypt (2010) reveal two main mechanisms. First, out-group attitudes among both separated communities significantly deteriorate after the construction of the wall thereby fuelling intergroup conflict. Second, when walls are built by states with sizeable out-group populations with kinship ties across the border, exacerbated grievances and reduced opportunity costs among the targeted communities generate incentives for terrorist organizations from the separated country to step up recruitment and terrorist attacks against the builder country. As a result, terrorist threats increase after the construction of the wall. These findings have critical scholarly and policy implications by demonstrating the unintended consequences of highly restrictive border policies and showing how walls are not only ineffective against terrorism but may ultimately exacerbate the problem they intend to resolve.

Dobrislav Dobrev (Federal Reserve Board)

“A Randomized Missing Data Approach to Robust Filtering and Forecasting“

Abstract: We put forward a simple new randomized missing data (RMD) approach to robust filtering of state-space models, motivated by the idea that the inclusion of only a small fraction of available highly precise measurements can still extract most of the attainable efficiency gains for filtering latent states, estimating model parameters, and producing out-of-sample forecasts. In our general RMD framework we develop two alternative implementations: endogenous (RMD-N) and exogenous (RMD-X) randomization of missing data. A degree of robustness to outliers and model misspecification is achieved by purposely randomizing over the utilized subset of seemingly highly precise but possibly misspecified or outlier contaminated data measurements in their original time series order, while treating the rest as if missing. Time-series dependence is thus fully preserved and all available measurements can get utilized subject to a degree of downweighting depending on the loss function of interest. The arising robustness-efficiency trade-off is controlled by varying the fraction of randomly utilized measurements or the incurred relative efficiency loss. As an empirical illustration, we show consistently attractive performance of our RMD framework in popular unobserved components models for extracting inflation trends. We further consider model extensions that more directly reflect inflation targeting by central banks and reveal its effectiveness through improved inflation forecasting.

„Who are the Crypto-Owners? Evidence from a German Personal Finance Management App“

Abstract: This study investigates the characteristics, behavioral preferences, and consumption profiles of individuals who own crypto assets. Our empirical analysis utilizes data from a German personal finance management app where users connect their bank accounts and depots. We conducted a survey and elicited behavioral factors and preferences for financial decision-making. By combining the survey data with account and depot transactions, we identify certain types of crypto owners. Furthermore, we conduct a factor analysis and reveal latent explanatory factors from consumption data. Our preliminary results suggest that especially male individuals with high levels of risk and time preferences tend to be more invested in crypto assets.

„Bank organizational culture and misconduct“

Abstract: We examine how and to what extent a bank’s culture influences that bank’s misconduct. We find that banks with a growth-oriented culture are more likely to receive enforcement actions whereas banks with a safety-oriented culture are less likely to receive enforcement actions. Our findings remain despite accounting for look ahead bias, measurement error and omitted variable bias. Using state-level bank branching deregulation following the Interstate Banking and Branching Efficiency act as exogenous shocks to the competitive environment in the banking system, we find evidence supporting a causal effect of corporate culture on misconduct in banks.

„What Do Employee Referral Programs Do? Measuring the Direct and Overall Effects of a Management Practice“

Abstract: Employee referral programs (ERPs) are randomly introduced in a grocery chain. Larger referral bonuses increase referrals and decrease referral quality, though the increase in referrals from having an ERP is modest. However, the overall effect of having an ERP is substantial, reducing attrition by roughly 15% and decreasing firm labor costs by up to almost 3%. This occurs, partly, because referrals stay longer than nonreferrals, but, mainly, because all workers stay longer in treated than control stores, even among stores where no referrals are made. The most-supported mechanism for these indirect effects is that workers value being involved in hiring.

„Polygyny, Timing of Marriage and Economic Shocks in Sub-Saharan Africa“

Abstract: This paper studies how local polygyny norms affect the equilibrium response of marriage markets to short-term changes in aggregate economic conditions. It develops a simple equilibrium marriage market framework with overlapping generations in which polygyny is modeled as a sequential one-to-one matching. The model generates predictions that are tested by revisiting the impact of rainfall shocks on the timing of marriage in Sub-Saharan Africa. Consistent with the model’s predictions, I find that the effect of droughts on child marriage is weaker where polygyny is more commonly practiced. The same shock leads to a large increase in the annual hazard of child marriage in monogamous areas but has no detectable effect in areas with high polygyny levels. In these areas, there is instead an increase in the market shares of young men that are looking for first/unique spouses at the expense of older men that are looking for second spouses. The differences in equilibrium outcomes on the marriage markets translate into differences in fertility onset and long term fertility levels.

Der Vortrag wird am Donnerstag, den 09. Dezember, von 12:00-13:30 online über Zoom stattfinden. Kontaktieren Sie bitte info@fww-ev.de für die Zugangsdaten.

Marius Brülhart (Université de Lausanne):

Who Bears the Burden of Local Taxes?

We study the incidence of local taxes on the welfare of heterogeneous residents. A structural model of imperfectly mobile households who differ in terms of income and family status allows us to back out preferences for local public goods and mobility parameters that vary by family status. We calibrate the model with plausibly causal tax-base and housing-price elasticity estimates. Based on municipality-level data for Switzerland, we find that households with children have stronger preferences for locally provided public services and are less mobile than households without children. This in turn implies that the burden of local taxes is mainly borne – linearity of taxes and capitalization into lower housing notwithstanding – by above-median income households without children.

4 Things Nobody tells you about Online News: A Model with Social Networks and Competition

Social media create a new type of incentives for news producers. Consumers share content, influence the visibility of articles and determine the advertisement revenues ensuing. I study the new incentives created by sharing and evaluate the potential quality of ad-funded online news. Producers rely on a subset of rational and unbiased consumers to spread news articles. The resulting news has low precision and ambiguous welfare effects. Producers’ incentive to invest in news quality increases with the private knowledge of the topic; hence, when information is most needed, the generated news tends to be of lesser quality. Competition does not necessarily improve news quality – it does so only if the sharing network is sufficiently dense. While ad-funded online news occasionally helps consumers take better decisions, it creates welfare mostly through entertainment. Some interventions, such as flagging wrong articles, substantially improve the outcome; other approaches, such as quality certification, do not.

Der Vortrag wird am Donnerstag, den 4. November 2021, von 12:00-13:30 s.t. stattfinden (Rempartstraße 16, Seminarraum 01012, 1.Stock). Zudem kann der Vortrag online besucht werden. Für die Zugangsdaten kontaktieren Sie gerne info@fww-ev.de.

„F.A. Hayek on the Political Economy of Endogenous Preferences: An Historical Overview and Contemporary Assessment“

In this paper, we analyse Hayek’s views on endogenous preferences. Perhaps surprisingly in the light of his remarks that economists ought to take people’s preferences as given, there are several places in Hayek’s economics and political economy where preference endogeneity plays a significant role. We begin by documenting those cases, providing an historical overview of Hayek’s views on preference endogeneity. We then go on to argue that in his work on theoretical psychology Hayek provides an account of the causal mechanisms through which people’s preferences can change in response to their social context. Finally, we assess Hayek’s views on preference endogeneity in the light of more recent work on the topic in behavioural economics, before going on to consider what Hayek’s analysis can add to contemporary debates in political economy.

„Immigration, Labor Markets and Discrimination: Evidence from the Venezuelan Exodus in Peru“

Venezuela is currently experiencing the biggest crisis in the history of Latin America. This has led to a large increase in emigration. According to recent estimates, there are a total of 5.2million Venezuelan immigrants worldwide with over 700,000 now living in Peru, which has led to an over 2 percent increase in the country’s population. Unlike in many other episodes of refugee migration, Venezuelan migrants are not only very similar in cultural terms, but are, on average, also more skilled than Peruvians. In this paper, we examine hostility and discrimination against Venezuelans in Peru. First, we examine Venezuelan’s perceptions about being discriminated against in Peru. Using an instrumental variable strategy, we document a causal relationship between the level of employment in the informal sector –where most immigrants are employed– and reports of discrimination. We then turn to study local’s labor market outcomes, reported crime rates and attitudes using a variety of data sources. Our findings show that a higher number of immigrants cause an improvement in labor market outcomes for locals, a decrease in reported crime, but still, locals in locations with higher number of immigrants have less trust in their neighbors, less community attachment and think they have a worse economic situation.

„Caught between Cultures: Unintended Consequences of Improving Opportunity for Immigrant Girls“
mit Gordon B. Dahl, Paul Frijters und Helmut Rainer

What happens when immigrant girls are given increased opportunities to integrate into the workplace and society, but their parents value more traditional cultural outcomes? We answer this question in the context of a reform which granted automatic birthright citizenship to eligible immigrant children born in Germany after January 1, 2000. Using survey data we collected from students in 57 schools and comparing those born in the months before versus after the reform, we find the introduction of birthright citizenship lowers measures of life satisfaction and self-esteem for immigrant girls by .32 and .25 standard deviations, respectively. This is especially true for Muslims, where parents are likely to prefer more traditional cultural outcomes than their daughters. Moreover, we find that Muslim girls granted birthright citizenship are less integrated into German society: they are both more socially isolated and less likely to self-identify as German. Exploring mechanisms for these unintended drops in well-being and assimilation, we find that immigrant Muslim parents invest less in their daughters’ schooling and that these daughters receive worse grades in school if they are born after the reform. Parents are also less likely to speak German with these daughters. Consistent with a rise in intrafamily conflict, birthright citizenship results in disillusionment where immigrant Muslim girls believe their chances of achieving their educational goals are lower and the perceived odds of having to forgo a career for a family rise. In contrast, immigrant boys experience, if anything, an improvement in well-being, integration, and schooling outcomes. Taken together, the findings point towards immigrant girls being pushed by parents to conform to a role within traditional culture, whereas boys are allowed to take advantage of the opportunities that come with citizenship. To explain these findings, we construct a simple game-theoretic model which builds on Akerlof and Kranton (2000), where identity-concerned parents constrain their daughter’s choices, and hence lower their daughter’s well-being, when faced with the threat of integration. Alternative models can explain some of the findings in isolation.

Jan Schnellenbach (TU Cottbus): „Behavioral extensions of Putnam’s two-level game of international negotiations“

In a seminal article, Robert Putnam (1988) models negotiations over international agreements as two-level games. Representatives of national governments are engaged in two simultaneous negotiations, with their international partners and with domestic interest groups and political parties whose support is needed for the implementation of any international agreement. Both games interact: International negotiations can change the constraints of national policy-making, and vice versa. We analyze the two-level game through a behavioral lens. In particular, it is discussed how incomplete information regarding domestic win sets affects international negotiating, and how Putnam’s two central mechanisms of reverberation and synergistic linkage can work under behavioral assumptions.

Karrieretag Freiburg

Exkursion Börsentag

Die Exkursionen des Börsentags des Börsenvereins Freiburg e. V. werden vom FWW e. V. unterstützt.

So wurde beispielsweise 2018 die Stuttgarter Börse von 20 finanzbegeisterten Studierenden besucht. Neben Vorträgen über die wichtigsten Fakten und Kennzahlen der Stuttgarter Börse sowie über Kryptowährungen und Blockchain, bekamen die Studierenden die Gelegenheit selbst in die Rolle eines Börsenmaklers zu schlüpfen und an einer Börsensimulation teilzunehmen. Abschließend durfte sogar der Handelsraum besichtigt werden.

2017 ging es in die Finanzmetropole Zürich. Dort wurde zuerst das Unternehmen Accenture besucht. Nach Einführung in die Design Thinking Technik durften die Studierenden in Gruppenarbeit im Rahmen eines Workshops ein Bankingprodukt entwickeln. Anschließend konnten auf dem Börsentag Zürich spannende Vorträge von Experten über Themen wie Kryptowährungen, allgemeine Marktentwicklungen und der generellen Vermögensverwaltung gehört werden. Zusätzlich gab es die Möglichkeit, sich an den vorhandenen Unternehmensständen über Tradingmöglichkeiten/-strategien zu informieren und mit den entsprechenden Unternehmensvertretern Kontakte zu knüpfen.

Blockchain Symposium

Das Blockchain Symposium beleuchtete Möglichkeiten, Limitierungen sowie Auswirkungen der Blockchain-Technologie und stellte gleichzeitig eine Plattform für den Austausch zwischen Wissenschaftler, Studierenden und Unternehmen dar.

Am 01. Dezember 2018 hat das erste Blockchain Symposium in Freiburg stattgefunden. Organisiert und geleitet wurde die Veranstaltung neben dem FWW e. V. auch von den studentischen Initiativen Börsenverein Freiburg (www.boersenverein-freiburg.de) und Foundersclub Freiburg (www.foundersclub-freiburg.de). Inhaltlich wurde die Veranstaltung von der Stadtverwaltung (hier „digital.freiburg“) und der Albert-Ludwigs-Universität Freiburg, die Ihre Räumlichkeiten zur Verfügung stellt, unterstützt. Als weiterer Unterstützer konnte auch „Freiburg Wirtschaft Touristik

und Messe GmbH & Co. KG“ (FWTM) gewonnen werden. Das Event wurde von Herr Treiber vom Blockchain Bundesverband moderiert.

Das Symposium für Studierende und Interessierte befasste sich mit den Möglichkeiten und Limitierungen der Blockchain-Technologie und zeigte außerdem deren Auswirkungen auf unsere Wirtschaft, Gesellschaft, unseren technischen Fortschritt und die Entwicklung unserer Wissenschaft. Dafür wurde ein breites Spektrum an Anwendungsmöglichkeiten dieser innovativen Technologien vorgestellt.

Dieses internationale Event fungierte als Brückenschlag zwischen Forschung und Praxis und bot eine Plattform zum Netzwerken und Austauschen zwischen Studierenden, Unternehmern und Wissenschaftlern.

Insbesondere ging es um einen einfachen Einstieg in die Technologie. Was ist Blockchain? Was kann die Technologie schon heute – was ist in naher Zukunft machbar? Zu den Teilnehmern dieses Events zählten neben Firmenvertretern von NEO, eine der weltweit bekanntesten Blockchain-Plattformen, auch Firmenvertreter eines großen Crypto- Exchanges aus dem Silicon Valley, sowie diverse Startups aus Tbilisi, Wien, Zug, Essen, Karlsruhe und Freiburg.

Mit mehr als 400 Teilnehmern bei den Vorträgen und Workshops war diese Veranstaltung ein voller Erfolg.
