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...

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...

Ignorance enables individuals to act immorally. This is well known in policy circles, where there is keen interest in lowering moral ignorance. In this paper, we study the (in)elasticity of moral ignorance, with respect to monetary incentives, social norms messages and moral context. We propose...

Throughout the Western world, people's policy preferences are correlated across domains in a strikingly similar fashion. Based on a simple model, we propose that what partly explains the particular internal structure of political ideology is heterogeneity in moral universalism: the extent to...

Literature in economics and psychology on moral behaviour explores the contexts in which people act in ways that are consistent or inconsistent with their past actions. Such inconsistencies appear to violate economists' assumption of rational consumer behaviour. In this note we show that a...

We document individual willingness to fight climate change and its behavioral determinants in a large representative sample of US adults. Willingness to fight climate change – as measured through an incentivized donation decision – is highly heterogeneous across the population. Individual...

This paper presents novel stylized facts about the global variation in universalism, leveraging nationally representative surveys across 60 countries (N=64,000). We find large variation in universalism within and across countries, which almost entirely reflects heterogeneity in people’s moral...

An extensive literature documents that people are willing to sacrifice personal material gain to adhere to a moral motive. Yet, less is known about what happens when moral motives are in conflict. We hypothesize that individuals engage in what we term “motive selection,” namely adhering to...

In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in sample estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation...
