Much of today’s software relies on programming code shared openly online. Yet, it is unclear why volunteer developers contribute to open-source software (OSS), a public good. We study OSS contributions of some 22,900 developers worldwide on the largest online code repository platform, GitHub,...

Why do people give when asked, but prefer not to be asked, and even take when possible? We show that standard behavioral axioms including separability, narrow bracketing, and scaling invariance predict these seemingly inconsistent observations. Specifically, these axioms imply that...

Private wealth is a crucial factor for the economic well-being of households. Key determinants of private wealth include intergenerational wealth transfers (gifts and inheritances), which are gaining importance since 1990, as research suggests. We conduct a detailed investigation of the...

We present the first causal evidence on the persistent impact of enduring competition on prosociality. Inspired by the literature on tournaments within firms, which shows that competitive compensation schemes reduce cooperation in the short-run, we explore if enduring exposure to a competitive...

We test the importance of social norms for market interactions associated with negative real-world externalities in a large-scale experiment with a heterogeneous population sample from Germany. The majority of experimental participants refuses to trade, thus behaving in a moral way. Our data...

In this paper, I analyze detailed data on intergenerational transfers in 4 countries (China, India, Japan, and the United States) from the "Japan Household Panel Survey on Consumer Preferences and Satisfaction (JHPS-CPS)" which has been conducted by the Institute of Social and Economic Research...

Cultural transmission arguably plays an important role in the determination of many fundamental preference traits (e.g., discounting, risk aversion and altruism) and most cultural traits, social norms, and ideological tenets ( e.g., attitudes towards family and fertility practices, and attitudes...

This paper studies quality choice in a model where consumers expect firms (or brands) to act altruistically. Under plausible assumptions regarding this altruism and the reaction of consumers to firms that demonstrate insufficient altruism, existing brands can face a larger demand for new...

A model is considered where firms internalize the regret costs that consumers experience when they see an unexpected price change. Regret costs are assumed to be increasing in the size of price changes and this can explain why the size of price increases is less sensitive to inflation than in...

The durability of health care treatment, the substantial technical change in health care treatment, and the prevalence of third-party payment interact to create substantial difficulty in measuring the price and output of health care. This paper provides a framework for analyzing the demand for...
