Culture and Student Achievement: The Intertwined Roles of Patience and Risk-Taking
Author:
Abstract:
Patience and risk-taking – two cultural traits that steer intertemporal decision-making – are fundamental to human capital investment decisions. To understand how they contribute to international differences in student achievement, we combine PISA tests with the Global Preference Survey. We find that opposing effects of patience (positive) and risk-taking (negative) together account for two-thirds of the cross-country variation in student achievement. In an identification strategy addressing unobserved residence-country features, we find similar results when assigning migrant students their country-of-origin cultural traits in models with residence-country fixed effects. Associations of culture with family and school inputs suggest that both may act as channels.

Dynamic Pricing in a Digitized World
Author:
Abstract:
Digital technologies favor the use of dynamic pricing, i.e., prices that vary unannounced for a product that basically remains unchanged. However, different forms of dynamic pricing are often mixed in the public discussion, which makes a meaningful analysis of the advantages and disadvantages of dynamic pricing difficult. The aim of this paper is to present the economic foundations of dynamic pricing as well as to discuss and to classify its design options. In addition, the paper assesses dynamic pricing from a buyer and seller perspective. Finally, the paper discusses implications for business research.

Mentoring and Schooling Decisions: Causal Evidence
Author:
Abstract:
Inequality of opportunity strikes when two children with the same academic performance are sent to diff erent quality schools because their parents di ffer in socio-economic status. Based on a novel dataset for Germany, we demonstrate that children are signi ficantly less likely to enter the academic track if they come from low socio-economic status (SES) families, even after conditioning on prior measures of school performance. We then provide causal evidence that a low-intensity mentoring program can improve long-run education outcomes of low SES children and reduce inequality of opportunity. Low SES children, who were randomly assigned to a mentor for one year are 20 percent more likely to enter a high track program. The mentoring relationship aff ects both parents and children and has positive long-term implications for children's educational trajectories.

On the Causes and Consequences of Deviations from Rational Behavior
Author:
Abstract:
This paper presents novel evidence for the prevalence of deviations from rational behavior in human decision making – and for the corresponding causes and consequences. The analysis is based on move-by-move data from chess tournaments and an identification strategy that compares behavior of professional chess players to a rational behavioral benchmark that is constructed using modern chess engines. The evidence documents the existence of several distinct dimensions in which human players deviate from a rational benchmark. In particular, the results show deviations related to loss aversion, time pressure, fatigue, and cognitive limitations. The results also demonstrate that deviations do not necessarily lead to worse performance. Consistent with an important influence of intuition and experience, faster decisions are associated with more frequent deviations from the rational benchmark, yet they are also associated with better performance.

Aging, Proximity to Death, and Religiousness
Author:
Abstract:
Considerable evidence has documented that the elderly are more religious and that religiousness is associated with better health and lower mortality. Yet, little is known about the reverse role of life expectancy or proximity to death, as opposed to age, for religiousness. This paper provides evidence for the distinct role of expected remaining life years for the importance of religion in individuals’ lives. We combine individual survey response data for more than 311,000 individuals from 95 countries over the period 1994-2014 with information from period life tables. Contrary to wide-held beliefs, religiousness decreases with greater expected proximity to death. The findings have important implications regarding the consequences of population aging for religiousness and associated outcomes.

Self-Assessment: The Role of the Social Environment
Author:
Abstract:
This study presents descriptive and causal evidence on the role of the social environment in shaping the accuracy of self-assessment. We introduce a novel incentivized measurement tool to measure the accuracy of self-assessment among children and use this tool to show that children from high socioeconomic status (SES) families are more accurate in their self-assessment, compared to children from low SES families. To move beyond correlational evidence, we then exploit the exogenous variation of participation in a mentoring program designed to enrich the social environment of children. We document that the mentoring program has a causal positive e ffect on the accuracy of children's self-assessment. Finally, we show that the mentoring program is most e ffective for children whose parents provide few social and interactive activities for their children.

Covid-19 Crisis Fuels Hostility against Foreigners
Author:
Abstract:
Intergroup conflicts represent one of the most pressing problems facing human society. Sudden spikes in aggressive behavior, including pogroms, often take place during periods of economic hardship or health pandemics, but little is known about the underlying mechanism behind such change in behavior. Many scholars attribute it to scapegoating, a psychological need to redirect anger and to blame an out-group for hardship and problems beyond one's own control. However, causal evidence of whether hardship triggers out-group hostility has been lacking. Here we test this idea in the context of the Covid-19 pandemic, focusing on the common concern that it may foster nationalistic sentiments and racism. Using a controlled money-burning task, we elicited hostile behavior among a nationally representative sample (n = 2,186) in a Central European country, at a time when the entire population was under lockdown and border closure. We find that exogenously elevating salience of thoughts related to Covid-19 pandemic magnifies hostility and discrimination against foreigners, especially from Asia. This behavioral response is large in magnitude and holds across various demographic sub-groups. For policy, the results underscore the importance of not inflaming racist sentiments and suggest that efforts to recover international trade and cooperation will need to address both social and economic damage.

Robust Contracting in General Contract Spaces
Author:
Abstract:
We consider a general framework of optimal mechanism design under adverse selection and ambiguity about the type distribution of agents. We prove the existence of optimal mechanisms under minimal assumptions on the contract space and prove that centralized contracting implemented via mechanisms is equivalent to delegated contracting implemented via a contract menu under these assumptions. Our abstract existence results are applied to a series of applications that include models of optimal risk sharing and of optimal portfolio delegation.

Two Field Experiments on Self-Selection, Collaboration Intensity, and Team Performance
Author:
Abstract:
We analyze how the team formation process influences the ability composition and performance of teams, showing how self-selection and random assignment affect team performance for different tasks in two natural field experiments. We identify the collaboration intensity of the task as the key driver of the effect of self-selection on team performance. We find that when the task requires low collaborative efforts, the team performance of self-selected teams is significantly inferior to that of randomly assigned teams. When the task involves more collaborative efforts, self-selected teams tend to outperform randomly assigned teams. We observe assortative matching in self-selected teams, with subjects more likely to match with those of similar ability and the same gender.

Financial Education Affects Financial Knowledge and Downstream Behaviors
Author:
Abstract:
We study the rapidly growing literature on the causal effects of financial education programs in a meta-analysis of 76 randomized experiments with a total sample size of over 160,000 individuals. The evidence shows that financial education programs have, on average, positive causal treatment effects on financial knowledge and downstream financial behaviors. Treatment effects are economically meaningful in size, similar to those realized by educational interventions in other domains and are at least three times as large as the average effect documented in earlier work. These results are robust to the method used, restricting the sample to papers published in top economics journals, including only studies with adequate power, and accounting for publication selection bias in the literature. We conclude with a discussion of the cost-effectiveness of financial education interventions.
