State Repression, Exit, and Voice
Author:
Abstract:
What is the political legacy of state repression? Using local variation in state repression during the Khmer Rouge genocide in Cambodia, we investigate the effects of repression on political beliefs and behavior. We find that past state repression decreases votes for an authoritarian incumbent while enhancing electoral competition and support for democratic values four decades later. At the same time, individuals become more cautious in their interactions with the local community: they exhibit less trust, participate less in community organizations, and engage less with local government. Our theoretical model suggests that these opposing forces arise because experiencing repression bolsters preferences for pluralism while also heightening the perceived cost of dissent. Consequently, citizens are more likely to support the opposition in elections (voice) but engage less in civil society (exit) to avoid publicly revealing their political views. Exploring channels of persistence, we demonstrate that repression cultivates a lasting fear of violence as a societal threat, and that genocide memorials and remembrance ceremonies maintain the collective memory of the atrocities.

Female Education and Social Change
Author:
Abstract:
Does access to education facilitate the emergence of a human capital elite from which social activists, and thus, social change can emerge? Assembling a city-level panel of the political, intellectual, and economic elite throughout German history, we find that the opening of schools providing secondary education for women increased their representation among the human capital elite. These elites challenged the status quo and developed critical ideas that resonated in cities with higher human capital, connecting women to form a social movement. We find no evidence of other city-specific indicators of economic and gender-specific cultural change affecting our results. Differential returns to education are also unrelated to the increasing representation of women among the human capital elite, as the opening of gender-specific schools has no impact on the opposite gender.

Social Preferences under the Shadow of the Future
Author:
Abstract:
Social interactions predominantly take place under the shadow of the future. Previous literature explains cooperation in indefinitely repeated prisoner’s dilemma as predominantly driven by self-interested strategic considerations. This paper provides a causal test of the importance of social preferences for cooperation, varying the composition of interactions to be either homogeneous or heterogeneous in terms of these preferences. Through a series of pre-registered experiments (N = 1,074), we show that groups of prosocial individuals achieve substantially higher levels of cooperation. The cooperation gap between prosocial and selfish groups persists even when the shadow of the future is increased to make cooperation attractive for the selfish and when common knowledge about group composition is removed.

The Taxation of Couples
Author:
Abstract:
Are reforms towards individual taxation politically feasible? Are they desirable from a welfare perspective? We develop a method to answer such questions and apply it to the US federal income tax since the 1960s. Main findings are: As of today, Pareto-improvements require a move away from joint taxation. Revenue-neutral reforms towards individual taxation are not Pareto-improving, but attract majoritysupport. Such reforms are rejected by Rawlsian welfare measures and supported by ones with weights that are increasing in the secondary earner’s income share. Thus, there is a tension between the welfare of “the poor” and the welfare of “working women.”

I'll Try That, Too - A Field Experiment in Retailing on the Effect of Variety During Display Promotions
Author:
Abstract:
The effect of variety on consumer choice has been studied extensively, with some stream of literature showing the positive effects on choice and others arguing that too many alternatives may result in negative consequences (i.e., choice deferral or no purchase at all), often referred to as choice overload. In a field experiment with a major chocolate brand conducted at a German retail chain, we test for variety during a price and display promotion. Participating stores either include the full variety of products on the display or a reduced selection (low variety). Contrary to the literature on choice overload, we find a significantly positive effect of the display promotion on unit sales, which is stronger for stores with high variety. Further findings show a stronger promotion uplift for less popular products in stores with high variety on the display. This suggests that more variety may increase consumers’ willingness to try new products, when the financial risk is low. We also test for the effect of product distribution on displays by analysing the number of facings. Additionally, we introduce an approach to determine an optimal space allocation of products on the display. Our findings suggest that an even distribution results in the highest profits for the retailer. We contribute to the literature on variety for consumer choices by offering insights from actual purchases with store-level scanner data of display promotions.

Persecution and Escape
Author:
Abstract:
We study the role of professional networks in facilitating emigration of Jewish academics dismissed from their positions by the Nazi government. We use individual-level exogenous variation in the timing of dismissals to estimate causal eects. Academics with more ties to early émigrés (emigrated 1933-1934) were more likely to emigrate. Early émigrés functioned as “bridging nodes” that facilitated emigration to their own destination. We also provide evidence of decay in social ties over time and show that professional networks transmit information that is not publicly observable. Finally, we study the relative importance of three types (family, community, professional) of social networks.

War and Science in Ukraine
Author:
Abstract:
We discuss the impacts of the Russian invasion on Ukrainian science. Using newly collected data, we show that the war has already had significant effects on science in Ukraine: research papers produced by Ukrainian scientists declined by about 10%, approximately 5% of the most prolific scientists are publishing with a foreign affiliation, 22% of top universities have faced destruction of physical capital, and international collaborations with Russian scientists have declined by more than 40%. Drawing upon the economics of science and innovation literature, we highlight three primary channels through which wars impact science: 1) the loss of human capital, 2) the destruction of physical capital, and 3) reductions in international scientific cooperation. The evidence from the literature on the long-run effects of losing human or physical capital indicates that shocks to physical capital can be remedied more easily than shocks to human capital. Our new data also suggests that human capital shocks are the main drivers of the reduction in Ukrainian research output that has occurred since the beginning of the war. Hence, reconstruction efforts should be focused on supporting scientists to continue in the research sector and to return to Ukraine after the war has ended.

The Lifecycle of Affirmative Action Policies and Its Effect on Effort and Sabotage Behavior
Author:
Abstract:
A main goal of affirmative action (AA) policies is to enable disadvantaged groups to compete with their privileged counterparts. Existing theoretical and empirical research documents that incorporating AA can result in both more egalitarian outcomes and higher exerted efforts. However, the direct behavioral effects of the introduction and removal of such policies are still under-researched. It is also unclear how specific AA policy instruments, for instance, head-start for a disadvantaged group or handicap for the privileged group, affect behavior. We examine these questions in a laboratory experiment in which individuals participate in a real-effort tournament and can sabotage each other. We find that AA does not necessarily result in higher effort. High performers that already experienced an existing AA-free tournament reduce their effort levels after the introduction of the AA policy. Additionally, we observe less sabotage under AA when the tournament started directly with the AA regime. The removal of AA policies, however, significantly intensifies sabotage. Finally, there are no overall systematic differences between handicap and head-start in terms of effort provision or sabotaging behavior.

Responsibility-Shifting through Delegation: Evidence from China’s One-Child Policy
Author:
Abstract:
We provide evidence on how responsibility-shifting through delegation occurred in China’s implementation of the one-child policy. We show that trust in local governments was reduced when they were the primary enforcer of the policy (1979–1990), while trust in neighbors was reduced when civilians were incentivized to report neighbors’ violations of the policy to the authorities (1991–2015). This effect was more pronounced among parents of a firstborn daughter, who were more likely to violate the policy due to the deep-rooted son preference. This study provides the first set of field evidence on the responsibility-shifting effect of delegation.

Productivity Spillovers among Knowledge Workers in Agglomerations: Evidence from GitHub
Author:
Abstract:
Software engineering is a field with strong geographic concentration, with Silicon Valley as the epitome of a tech cluster. Yet, most studies on the productivity effects of agglomerations measure innovation with patent data, thus capturing only a fraction of the industry's activity. With data from the open source platform GitHub, our study contributes an alternative proxy for productivity, complementing the literature by covering a broad range of software engineering. With user activity data covering the years 2015 to 2021, we relate cluster size to an individual's productivity. Our findings suggest that physical proximity to a large number of other knowledge workers in the same field leads to spillovers, increasing productivity considerably. In further analyses, we confirm the causal relationship with an IV approach and study heterogeneities by cluster size, initial productivity and project characteristics.
