Societies prohibit many transactions considered morally repugnant, although potentially efficiency-enhancing. We conducted an online choice experiment to characterize preferences for the morality and efficiency of payments to kidney donors. Preferences were heterogeneous, ranging from...

We investigate the elasticity of moral ignorance with respect to monetary incentives and social norm information. We propose that individuals suffer from higher moral costs when rejecting a certain donation, and thus pay for moral ignorance. Consistent with our model, we find significant...

We explore the role of cheap excuses in product choice. If a product improves upon one ethically relevant dimension, agents may care less about other, completely independent ethical facets of the product. This "static moral self-licensing" would extend the logic of the well studied moral...

The neoclassical model in economics envisages humans as amoral and self-regarding (Econs). This model, also known as the homo-economicus model, is not consistent with the empirical evidence. In light of the evidence, the continued use of the homo-economicus model is baffling. It also stymies...

Markets are ubiquitous in our daily life and, despite many imperfections, they are a great source of human welfare. Nevertheless, there is a heated recent debate on whether markets erode social responsibility and moral behavior. In fact, competitive pressure on markets may create strong...

This paper studies how individual characteristics, institutions, and their interaction influence moral decisions. We validate a moral paradigm focusing on the willingness to accept harming third parties. Consequences of moral decisions are real. We explore how moral behavior varies with...

The widespread use of markets leads to unprecedented material well-being in many societies. We study whether market interaction, as a side effect, erodes moral values. An encompassing understanding of the virtues and vices of markets, including their possible impact on moral values, is necessary...

We revisit Max Weber's hypothesis on the role of Protestantism for economic development. We show that nationalism is crucial to both, the interpretation of Weber's Protestant Ethic and empirical tests thereof. For late nineteenth-century Prussia we reject Weber's suggestion that Protestantism...

This paper studies the impact of a key feature of competitive markets on moral behavior: the possibility that a competitor will step in and conclude the deal if a conscientious market actor forgoes a profitable business opportunity for ethical reasons. We study experimentally whether people...

Using an incentivized online classroom experiment, we assess the effectiveness of deontological vs. consequentialist moral reminders. Participants were told that they are the responsible public servant for acquiring a Covid-19 vaccine, providing them with the opportunity to generate some extra...
