Institutions are important for proper economic performance, but are replaceable by trust or other social norms. We show that when proper institutions and trust are missing, integrity of the individuals can replace them. We construct a model of a transactions-based economy with contracts...

To investigate the relation between trust and formal institutions, we analyze bilateral trade patterns in a sample of 16 European countries between 1996-2009. Trust in trading partners has a significant positive effect on bilateral trade. However, our results suggest that trust and formal...

I study a sequential-move public goods game based on the notion that leadership comes with an obligation; conscientious leadership. Provision by the leader of an amount of the public good below a minimum imposes a psychological cost on the follower which increases his unit cost of contribution....

Using a laboratory experiment, we present first evidence that stigmatization through public exposure causally reduces the take-up of an individually beneficial transfer. Our design exogenously varies the informativeness of the take-up decision by varying whether transfer eligibility is based on...

A burgeoning literature in economics has started examining the role of social norms in explaining economic behavior. Surprisingly, the vast majority of this literature has studied social norms in asocial decision settings, where individuals are observed to act in isolation from each other. In...

We present the first randomized survey experiment in the context of tax compliance to assess the role of social norms and reciprocity for intrinsic tax morale. We find that participants in a social-norm treatment have lower tax morale relative to a control group while participants in a...

Throughout human history, informal sanctions by peers were ubiquitous and played a key role in the enforcement of social norms and the provision of public goods. However, a considerable body of experimental evidence suggests that informal peer sanctions cause large collateral damage and...

It has been argued that guilt aversion (the aversion to violate others' expectations) and the compliance to descriptive social norms (the aversion to act differently than others in the same situation) are important drivers of human behavior. We show in a formal model that both motives are...

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...

In this paper we treat an individual's health as a continuous variable, in contrast to the traditional literature on income insurance, where it is regularly treated as a binary variable. This is not a minor technical matter; in fact, a continuous treatment of an individual's health sheds new...
