We study the developmental roots of cooperation in 929 young children, aged 3 to 6. In a unified experimental framework, we examine pre-registered hypotheses about which of three fundamental pillars of human cooperation - direct reciprocity, indirect reciprocity, and third-party punishment -...

Large Language Models (LLMs) have the potential to profoundly transform and enrich experimental economic research. We propose a new software framework, "alter_ego", which makes it easy to design experiments between LLMs and to integrate LLMs into oTree-based experiments with human subjects. Our...

Luxury brands are related to two major mechanisms of social adaptation: value-expressive and social-adjustive. Researchers have established that these two functions are likely to influence customer purchase intention. Additionally, evidence suggests an interaction between sustainability beliefs...

Since formal rules can only partially reduce opportunistic behavior, third-party sanctioning to promote fairness is critical to achieving desirable social outcomes. Social norms may underpin such behavior, but they can also undermine it. We study one such norm the "don't be a toad" norm, as it...

I review the academic literature on defined contribution retirement plan design and participant behavior. While adoption of automatic enrollment has significantly increased participation rates, recent studies find the long-run effects on savings are smaller than the short-run effects, with some...

We investigate how heterogeneous social preferences affect the communication of painful information in social relationships. We characterize the existence conditions for a pooling equilibrium in which individuals conceal painful information because revealing the latter would signal that they are...

In prosocial decisions, decision-makers are inherently uncertain about how their decisions impact others’ utility – we call this interpersonal uncertainty. We show that people’s response to interpersonal uncertainty shapes well-known patterns of prosocial behavior. First, using standard...

Every month, millions of women worldwide face challenges managing their menstrual hygiene, suffering negative impacts on their health, education, and productivity. Cultural taboos and social norms may contribute to harmful health behaviors and may also interfere with attempts to improve...

We analyze gender bias in entrepreneurship finance. Access to finance is crucial for entrepreneurial success, yet women are particularly constrained. We structurally unpack whether loan officers evaluate business ideas and implementation constraints differently for male and female entrepreneurs,...
