The decision how to share resources with others often needs to be taken under uncertainty on its allocational consequences. Although risk preferences are likely important, existing research is silent about how social and risk preferences interact in such situations. In this paper we provide...

Redistribution is an inevitable feature of collective pension schemes and economic experiments have revealed that most people have a preference for redistribution that is not merely inspired by self-interest. Interestingly, little is known on how these preferences interact with preferences for...

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...

An important element for the public support of policies is their perceived justice. At the same time most policy choices have uncertain outcomes. We report the results of a first experiment investigating just allocations of resources when some recipients are exposed to uncertainty. Although,...

We report results from the first experimental study of round-robin tournaments. In our experiment, we investigate how the prize structure affects the intensity, fair-ness, and dynamic behavior in sequential round-robin tournaments with three players. We compare tournaments with a second prize...

This paper explores whether social preferences influence portfolio choices of retail investors. We use administrative investor trading records which we link to decisions of the same investors in experiments with real money at stake. We show that social preferences rather than return expectations...

We report two information cascade game experiments that directly test the impact of altruism on observational learning. Participants interact in two parallel sequences, the observed and the unobserved sequence. Only the actions of the observed entail informational benefits to subsequent...

Most large-scale economic experiments use a between-subjects random incentive system-BRIS-which selects a subset of the participants at random and offers real payment only to the selected participants. We evaluate the relative impact of nominal payoffs and the selection probability on the...

The completeness axiom of choice has been questioned for long, and in response, theoretical models of decision making allowing for incomplete preferences have been developed. So far the theoretical accomplishments have however not been paired with empirical evidence on the actual existence of...

In a series of experiments conducted in Belgium (Wallonia and Flanders), France and the Netherlands, we compare behavior regarding tax evasion and welfare dodging, with and without information about others' behavior. Subjects have to decide between a 'registered' income, the realization of which...
