We analyse the effects of insider trading on real investment and welfare, and the consequences of different regulatory policies: a disclose-or-abstain rule, ‘fair’ disclosure, laissez-faire and forbidding insider trades based on ‘precise’ information. We perform the analysis in a model...

We propose a critical review of recent developments in exchange rate economics. This new strand of research is motivated by some very stark empirical evidence, relating exchange rate returns to order flow. Plenty of empirical evidence shows that order flow, i.e. the imbalance in the sequence of...

The lemons model assumes that owners of used cars have an informational advantage over potential buyers with respect to the quality of their vehicles. Owners of bad cars will try to sell them to unsuspecting buyers while owners of good cars will hold on to theirs. Consequently, the quality of...

Under contingent fees the attorney gets a share of the judgement; under conditional fees the lawyer gets an upscale premium if the case is won which is, however, unrelated to the adjudicated amount. We compare conditional and contingent fees in a principal-agent framework where the lawyer...

We consider a setting in which two potential merger partners each possess private information pertaining both to the profitability of the merged entity and to stand-alone profits, and investigate the extent to which this private information makes ex-post regret an unavoidable phenomenon in...

We consider second-price and first-price auctions in the symmetric independent private values framework. We modify the standard model by the assumption that the bidders have reference-based utility, where the reserve price (minimum bid) plays the role of the reference point. In contrast to the...

This paper develops a theoretical model of how bookmakers’ odds are determined, given varying levels of inside information on the part of punters. Bookmakers’ attitudes towards risk and the degree of competition between them will influence bookmaker behaviour. Using a data set of 1696 races...

I develop a model of group decision-making, in which a committee generates proposals and holds open discussions, but the ultimate decision is either taken by a leader (decision by authority) or by majority vote. Optimal communication processes are studied that combine both cheap talk statements...

We study the effects of allocative and informational externalities in (multi-object) auctions and related mechanisms. Such externalities naturally arise in models that embed auctions in larger economic contexts. In particular, they appear when there is downstream interaction among bidders after...

Instrumental variable estimation requires untestable exclusion restrictions. With policy effects on individual outcomes, there is typically a time interval between the moment the agent realizes that he may be exposed to the policy and the actual exposure or the announcement of the actual...
