The paper introduces a notion of complementarity (substitutability) of two signals which requires that in all decision problems each signal becomes more (less) valuable when the other signal becomes available. We provide a general characterization which relates complementarity and...

We experimentally test overconfidence in investment decisions by offering participants the possibility to substitute their own for alternative investment choices.Overall, 149 subjects participated in two experiments, one with just one risky asset, the other with two risky assets. Overconfidence...

Overbidding in sealed-bid second-price auctions (SPAs) has been shown to be persistent and associated with cognitive ability. We study experimentally to what extent cross-game learning can reduce overbidding in SPAs, taking into account cognitive skills. Employing an order-balanced design, we...

This paper reports two laboratory studies designed to study the impact of public informationabout past departure rates on congestion levels and travel costs. Our experimental design isbased on a discrete version of Arnott, de Palma, and Lindsey’s (1990) bottleneck model wheresubjects have to...

We study the steady state of a market with incoming cohorts of buyers and sellers who are matched pairwise and bargain under private information. We first consider generalized random-proposer take-it-or-leave-it offer games (GRP TIOLI games). This class of games includes a simple random-proposer...
