We document that trust in public institutions — and particularly trust in banks, business and government — has declined over recent years. U.S. time series evidence suggests that this partly reflects the pro-cyclical nature of trust in institutions. Cross-country comparisons reveal a clear...

In recent decades, the immigration of workers and refugees to Europe has increased substantially, and the composition of the population in many countries has consequently become much more heterogeneous in terms of ethnic background. If people exhibit in-group bias in the sense of being more...

Economic and social interaction takes place between individuals with heterogeneous characteristics. We investigate experimentally the emergence and informal enforcement of different contribution norms to a public good in homogeneous and different heterogeneous groups. When punishment is not...

We explore network effects on generosity for different network dimensions. To this end we elicit multiple network dimensions (friendship, social support, economic exchange, etc.) in a rural village in the Southern hemisphere and measure generosity with a sequence of dictator games conducted in...

In this paper, we revisit the association between happiness and inequality. We argue that the interaction between the perceived and the actual fairness of the income generation process affects this association. Building on a simple model of individual labor-market participation under...

Different from traditional gift exchange experiments, we study a field experiment where a random subsample of participants in the Swiss Labor Force Survey was sent vouchers to be used in adult training courses. Importantly for our purposes, actual voucher redemption can be traced. This gives the...

Does the Internet undermine social capital or facilitate inter-personal and civic engagement in the real world? Merging unique telecommunication data with geo-coded German individual-level data, we investigate how broadband Internet affects several dimensions of social capital. One...

This research establishes that the emergence, prevalence, recurrence, and severity of intrastate conflicts in the modern era reflect the long shadow of prehistory. Exploiting variations across national populations, it demonstrates that genetic diversity, as determined predominantly during the...

We examine whether individuals' experienced levels of income inequality affect their preferences for redistribution. We use several large nationally representative datasets to show that people who have experienced higher inequality during their lives are less in favor of redistribution, after...

With the rise of the far-right parties in the European parliamentary elections, concerns over immigration and national identity have again come into the limelight. In this paper, we document the empirical relationships between immigration, native concerns over the economic and cultural impact of...
