We introduce a generalized theoretical approach to study imitation models and subject the models to rigorous experimental testing. In our theoretical analysis we find that the different predictions of previous imitation models are due to different informational assumptions, not to different...

A well-known result by Vega-Redondo (1997) implies that in symmetric Cournot oligopoly, imitation leads to the Walrasian outcome where price equals marginal cost. In this paper, we show that this result is not robust to the slightest asymmetry in fixed costs. Instead of obtaining the Walrasian...

Do criminals maximise money? Are criminals more or less selfish than the average subject? Can prisons apply measures that reduce the degree of selfishness of their inmates? Using a tried and tested tool from experimental economics, we cast new light on these old criminological questions. In a...

In many economic contexts, an elusive variable of interest is the agent's expectation about relevant events, e.g. about other agents' behavior. Recent experimental studies as well as surveys have asked participants to state their beliefs explicitly, but little is known about the causal relation...

The Coase theorem posits: If [1] property rights are perfect, [2] contracts are enforceable, [3] preferences are common knowledge, and [4] transaction costs are zero, then the initial alloca-tion of property rights only matters for distribution, not for efficiency. In this paper we claim that...

Donors may often not be sure whether a recipient really deserves their help. Does this uncertainty deter generosity? In an experiment we find that, to the contrary, under most specifications of uncertainty, dictators give more, compared with the donation the same dictator makes to a recipient...

In a laboratory experiment designed to capture key aspects of the interaction between physicians and patients, we study the effects of medical insurance and competition in the guise of free choice of physician, including observability of physicians' market shares. Medical treatment is an example...
