We use a controlled laboratory experiment to study the causal impact of income decreases within a time period on redistribution decisions at the end of that period, in an environment where we keep fixed the sum of incomes over the period. First, we investigate the effect of a negative income...

Substantial evidence has accumulated in recent empirical works on the limited ability of the Nash equilibrium to rationalize observed behavior in many classes of games played by experimental subjects. This realization has led to several attempts aimed at finding tractable equilibrium concepts...

Almost all economic and public choice models assume that all people are exclusively pursuing their own material self-interests and do not care about "social" goals per se. Several (laboratory) experiments address the question of the general validity of this assumption. A consistent conclusion...

Experimental and observational studies have highlighted the importance of agents being conditionally cooperative when facing a social dilemma. We formalize this mechanism in a theoretical model that portrays a small community having joint access to a common pool resource. The diffusion of norms...

The assumptions that subjects hold beliefs and that the chosen actions are not altered by a proper elicitation of these beliefs are widely used in economics. In this paper I experimentally test whether the second assumption is correct. Especially controlling for different game properties, I find...

This paper studies the incentives for international cooperation if (some) countries prefer a more equitable distribution of per capita emission levels. The impact of such an equity preference is analyzed first for a bilateral, and then for a multilateral environmental problem. We show that -...

This paper studies whether conformism behavior affects individual outcomes in crime. We present a social network model of peer effects with ex-ante heterogeneous agents and show how conformism and deterrence affect criminal activities. We then bring the model to the data by using a very detailed...

We study the broken windows theory with a field experiment in a shared area of a workplace in academia (department common room). We explore academics’ and postgraduate students’ behaviour under an order condition (clean environment) and a disorder condition (messy environment). We find...
