Information asymmetries are important in theory but difficult to identify in practice. We estimate the empirical importance of adverse selection and moral hazard in a consumer credit market using a new field experiment methodology. We randomized 58,000 direct mail offers issued by a major South...

Microinsurers strive to simplify products and their pricing, a trend that runs counter to the customization and complex underwriting of insurance in richer markets. While necessary to reduce costs and reach wide scale, this trend opens microinsurance markets to problems of information...

We study the effect of transaction costs (e.g., a trading fee or a transaction tax, like the Tobin tax)on the aggregation of private information in financial markets. We analyze a financial market à la Glosten and Milgrom, in which informed and uninformed traders trade in sequence with a market...

Non-strategic firms with rational expectations make investment and emissions decisions. The investment rule depends on firms' beliefs about future emissions policies. We compare emissions taxes and quotas when the (strategic) regulator and (nonstrategic) firms have asymmetric information about...

Global games of regime change that is, coordination games of incomplete information in which a status quo is abandoned once a sufficiently large fraction of agents attacks it have been used to study crises phenomena such as currency attacks, bank runs, debt crises, and political change. We...

In a recent paper, Hart and Moore (2008) introduce new behavioral assumptions that can explain long term contracts and important aspects of the employment relation. However, so far there exists no direct evidence that supports these assumptions and, in particular, Hart and Moore's notion that...

We have experimentally tested a theory of bounded rational behavior in a "lemon market". It provides an explanation for the observation that real world players successfully conclude transactions when perfect rationality predicts a market collapse. We analyzed two different market designs :...

Wir nutzen die Ergebnisse eines Experiments über Lemons-Märkte, um wirtschaftspolitische Folgerungen über die EU-Verbraucherschutzregulierung von 1999 abzuleiten. Die beiden Marktdesigns, die im Experiment getestet wurden, unterscheiden sich hinsichtlich des Grades, zu dem die Verbraucher das...

In this paper we experimentally test a theory of boundedly rational behavior in a "lemons market." We analyzed two different market designs, for which perfect rationality implies complete and partial market collapse, respectively. Our empirical observations deviate substantially from these...
