We report results from an incentivized laboratory experiment to provide controlled evidence on the causal effects of alcohol consumption on risk preferences, time perception and altruism. Our design allows disentangling the pharmacological effects of alcohol intoxication from those mediated by...

How does the tax system's complexity affect people's reaction to tax changes? To answer this question, we conduct a real-effort experiment in which subjects receive a piece rate and face a set of taxes. In one treatment the tax system is simple; in the other treatment it is highly complex. The...

Becker's theory of taste-based discrimination predicts that relative employment of the discriminated social group will improve if there is a decrease in the level of prejudice for the marginally discriminating employer. In this paper we experimentally test this prediction offered by Becker...

This paper is concerned with a policy oriented macroeconomic experiment involving an 'international' economy with a relatively small 'home' country and a large 'foreign' country. It compares the economic performance of two alternative tax systems as a means to finance unemployment benefits: a...

We study the intrapersonal relationship between trust and reciprocity in a laboratory experiment. Reciprocal subjects trust significantly more than selfish ones. This finding raises questions about theories of social preferences which predict that "fairer" players should trust less.

Fungibility of money is a central principle in economics. It implies that any unit of money is substitutable for another and that the composition of income is irrelevant for consumption. We find in a field experiment that even in a simple, incentivized setup many subjects do not treat money as...

We experimentally study the influence of local information conditions on elite capture and social exclusion in community-based development schemes with heterogeneous groups. Not only information on the distribution of aid resources through community-based schemes, but also information on who...

We investigate the impact of obstetrician supervision, as opposed to midwife supervision, on the short-term health of low-risk newborns. We exploit a unique policy rule in the Netherlands that creates a large discontinuity in the probability of a low-risk birth being attended by an obstetrician...

We estimate the causal effect of having full health insurance on health care expenditures. We take advantage of a unique quasi-experimental setup in which deductibles and co-payments were zero in a managed care plan, and non-zero in regular insurance, until a policy change forced all individuals...

Although learning-by-doing is believed to be an important source of productivity growth, there is limited evidence that production volume affects productivity in a causal sense. We document evidence of learning-by-doing in a highly skilled profession where stakes are high; advanced cancer...
