In a punishment experiment, we separate the demand for punishment in general from the demand to conduct punishment personally. Subjects experience an unfair split of their earnings from a real effort task and have to decide on the punishment of the person who determines the distribution. First,...

This paper provides experimental evidence showing that indirect reciprocity may important in economic decision making and in the development of group norms. We study a 'repeated helping game' with random pairing in large groups, with individuals equally divided between donors and recipients....

We investigate expectation formation in a controlled experimental en-vironment. Subjects are asked to predict the price in a standard asset pricingmodel. They do not have knowledge of the underlying market equilibrium equa-tions, but they know all past realized prices and their own predictions....

This discussion paper led to a publication in the <I>Journal of Economic Dynamics & Control</I>. Volume 36(8), pp. 1101-1120.<P> Recent studies suggest that the type of strategic environment or expectation feedback can have a large impact on whether the market can learn the rational fundamental price. We...</p></i>

Theoretical research on claims problems has concentrated on normative properties and axiomatizations of solution concepts. We complement these analyses by empirical evidence on the predictability of three classical solution concepts in a bankruptcy problem. We examine both people's impartial...

This is an experimental study of a three-player power-to-take game where a take authority is matched with two responders. The game consists of two stages. In the first stage, the take authority decides how much of the endowment of each responder that is left after the second stage will be...

This discussion paper led to a chapter in: (K.R. Schenk-Hoppe & T. Hens (Eds.,)) <I>Handbook of Financial Markets: Dynamics and Evolution</I>, Amsterdam:North Holland/Elsevier, 2009.<P> Traditional finance is built on the rationality paradigm. This chapter discusses simple models from an alternative...</p></i>

This paper investigates an implication of the self-serving bias for reciprocalresponses. It is hypothesized that negative intentionality matters more thanpositive intentionality for reciprocating individuals with a self-servingattributional style. Experimental evidence obtained in the hot...

Recent theoretical work shows that folk theorems can be developed for infiniteoverlapping generations games. Cooperation in such games can be sustained as aNash equilibrium. Besides the efficient cooperative equilibrium there is alsothe inefficient non-cooperative equilibrium. This paper...

In this paper we conduct a laboratory experiment to test the extent to which Moore and Repullo’s subgame perfect implementation mechanism induces truth-telling in practice, both in a setting with perfect information and in a setting where buyers and sellers face a small amount of uncertainty...
