This paper experimentally studies the role of search cost in duopoly markets where sellers may be able to coordinate pricing decisions. We vary the level of search cost and whether sellers can communicate. While we find that consumers are more likely to invest in search when cost is reduced, we...

When forming policy under conditions of extreme uncertainty, the optimal approach seems to be a process by which the policy decision is divided into multiple stages, or in other words, an experimental approach. The optimal legal vehicle for such policy experimentation is what I call...

Courts are rarely asked to judge beauty. Such a subjective practice would normally be anathema to the ideal of objective legal standards. However, one area of federal law has a long tradition of explicitly requiring courts to make aesthetic decisions: the law of design. New designs may be...

Understanding what determines the extent to which economic agents tell the truth to their regulating authority is of major economic importance, from banking to environmental protection. To this end, we examine truth-telling of German commercial fishermen in an artefactual field experiment. Their...

Just as employers face uncertainty when hiring workers, workers also face uncertainty when accepting employment, and bad employers may opportunistically depart from expectations, norms, and laws. However, prior research in economics and information sciences has focused sharply on the employer's...

The opportunity to voice one's opinion about a decision is a fundamental aspect of procedural fairness and applies to a large variety of economic interactions. Voice may influence decision makers, but at the same time it shapes behavior of those who can voice their opinion. We study the latter...

Economic theory suggests that gasoline retail markets are prone to collusive behavior. Oligopoly market structures prevail, market interactions occur frequently, prices are highly transparent, and demand is rather inelastic. A recent sector inquiry in Germany backed suspicions of tacit collusion...

Many have advocated for the expansion of peer review to improve scientific judgments in law and public policy. One such test case is the patent examination process, with numerous commentators arguing that scientific peer review can solve informational deficits in patent determinations. We...

Petrol prices tend to be subject to regular changes, often changing more than once a day in many countries, and the number of changes appears to increase. For example, a recent sector inquiry by Germany's competition authority has found that the number of price changes has almost tripled between...
