Why do people who normally refrain from committing illegalities become digital pirates? In this paper we use a theoretical model of digital piracy combined with a game-theoretic mechanism of social norm formation to argue that no social stigma is attached to digital piracy because the latter has...

This study investigates the effects of unfair enforcement of institutional rules on public good contributions, personal and social norms, and trust. In a preregistered online experiment (n = 1,038), we find that biased institutions reduce rule compliance compared to fair institutions. However,...

A well-known result by Vega-Redondo (1997) implies that in symmetric Cournot oligopoly, imitation leads to the Walrasian outcome where price equals marginal cost. In this paper, we show that this result is not robust to the slightest asymmetry in fixed costs. Instead of obtaining the Walrasian...

Cultural and institutional differences among nations may result in differences in the ratios of marginal costs of goods in autarchy and thus be the basis of specialization and comparative advantage, as long as these differences are not eliminated by trade. We provide an evolutionary model of...

Using data from the German Socio-Economic Panel from 1984-2009, we follow persons from their working life into their retirement years and find that, on average, employed people maintain their life satisfaction upon retirement, while long-term unemployed people report a substantial increase in...

I estimate the effects of collaborative and adversarial intergroup contact. I randomly assigned Indian men from different castes to participate in cricket leagues or to serve as a control group. League players faced variation in collaborative contact, through random assignment to...

We consider an expanded notion of social norms that renders them belief-dependent and partial, formulate a series of related testable predictions, and design an experiment based on a variant of the dictator game that tests for empirical relevance. Main results: Normative beliefs influence...

We show that the discontinuity in the distribution of surveyed female income shares at the margin where a woman would outearn her partner is primarily driven by norm induced misreporting in surveys. We draw on unique Swiss data combining survey and administrative information for the same...

Can social norms affect fundamental patterns of behavior such as income effects? Studies of determinants of giving to charities and other individuals yield a wide range of income-effect estimates. We conduct two experiments to first test whether the effect of income on charitable giving depends...
