This paper examines the interactive effect of distance and trade on international conflict and cooperation. The effect of geographic distance depends on trade, while the effect of trade varies with geographic distance. Trade reduces conflict to a greater extent when dyads are geographically...

Redistribution across individuals in a one-year-period framework is an empirically intensely studied question. However, a substantial share of annual redistribution might turn out to serve individual insurance in a longer perspective, reducing the level of actual redistribution across...

This paper considers the effect of status or relative income on work effort combining experimental evidence from a gift-exchange game with ISSP survey data. We find a consistent negative effect of others' incomes on individual effort in both datasets. The individual's rank in the income...

Cooperation among people who are not related to each other is sustained by the availability of punishment devices which help enforce social norms (Fehr and Gc̃hter, 2002). However, the rationale for costly punishment remains unclear. This paper reports the results of an experiment investigating...

This paper reports the results of an experimental investigation which allows a deeper insight into the nature of social preferences amongst organized criminals and how these differ from "ordinary" criminals on the one hand and from the non‐criminal population in the same geographical area on...

This paper investigates the driving forces behind informal sanctions in cooperation games and the extent to which theories of fairness and reciprocity capture these forces. We find that cooperators' punishment is almost exclusively targeted towards the defectors but the latter also impose a...

Social experiments are powerful sources of information about the effectiveness of interventions. In practice, initial randomization plans are almost always compromised. Multiple hypotheses are frequently tested. "Significant" effects are often reported with p-values that do not account for...

We study the political economy of policy innovations during the U.S. welfare reform in 1996. Specifically, we investigate how reputation concerns among governors influence the decision to experiment with welfare policies. In line with a political agency model, our empirical results suggest that...

This paper distills and extends recent research on the economics of human development and social mobility. It summarizes the evidence from diverse literatures on the importance of early life conditions in shaping multiple life skills and the evidence on critical and sensitive investment periods...

The public health measures implemented by governments to limit the spread of the COVID-19 pandemic will produce significant economic consequences that are likely to exacerbate social and economic inequalities. In this paper we provide a framework to analyse how income inequality, besides other...
