In trials witnesses often slant their testimony in order to advance their own interests. To obtain truthful testimony, the law relies on cross-examination under threat of prosecution for perjury. We show that perjury law is an imperfect truthrevealing mechanism. Moreover, we develop a...

Witnesses often gain by slanting testimony. Courts try to elicit the truth with perjury rules. Perjury is not truth-revealing; truth revelation is, however, possible. With a truth-revealing mechanism the judge will get little testimony because the defendant will not present witnesses with...

We analyze whether corporate leniency programs should grant full immunity to the first self-reporting firm regardless of the amount of evidence provided. We distinguish between two firms, one of them providing high and one only low evidence. We show that awarding full amnesty also to the low...

We model the Catholic Church as a heterogeneous club managed by a specialized agency that pursues the enlargement of the club within given constraints. Religious indulgences induce the self selection of members, based on their attitudes towards risk. Highly risk-averse members do not relax their...

We consider a model of optimal law enforcement according to which self-reporting may be considered in mitigation. After committing a crime, individuals get a private update of their probability of apprehension. Hence, self-enforcing has an option value of self-reporting, since criminals can...

This paper shows that investors may want fund managers to acquire and trade on short-term instead of more profitable long-term information. This improves learning about managerial ability from performance observations, for two reasons. Firstly, short-term information is of higher quality, which...

We claim that Posner's nuisance rule maintains the efficiency feature even under severe informational asymmetry. This paper, as a critical assessment of an overly complicated order-reporting mechanism by Kim [2002], argues that Posner's original value-reporting mechanism alone is enough to...

Applying an indirect evolutionary approach with endogenous preference formation, we show that a legal system can induce players to reward trust even if material incentives dictate to exploit trust. By analyzing the crowding out or crowding in of trustworthiness implied by various verdict rules,...

Sunk costs and uncertainty characterize many public policy changes, as well as private investments. The Dixit-Pindyck theory of investment under uncertainty can then be applied to policy reforms, generating a positive option value to delaying a policy reform. The potential to adjust enforcement...

It has been argued that it is inefficient to restrict the ability of the rich to buy better legal defense than the poor because such restrictions lead to overdeterrence of the wealthy, who have a higher opportunity cost of imprisonment. We show that the ability of the rich to buy a lower...
