When penalties for first-time offenders are restricted, it is typically optimal for the lawmaker to overdeter repeat offenders. First-time offenders are then deterred not only by the (restricted) fine for a first offense, but also by the prospect of a large fine for a subsequent offense. Now...

We analyze a strategic trading model where an overconfident insider is required to publicly disclose his trades after the fact. We find the more confident insider is more concerned about the effect the initial trading has on the future.

A restricted-perceptions equilibrium exists in which risk-averse agents believe stock prices follow a random walk with a conditional variance that is self-fulfilling. When agents estimate risk, bubbles and crashes arise. These effects are stronger when agents allow for ARCH in excess returns.

Do corrupt people self select themselves in professions where the scope of corruption is high? We conduct a corruption experiment with private sector job aspirants and aspirants of Indian bureaucracy. The game models embezzlement of resources in which “supervisors” evaluate the performance...

We conduct a field experiment on tax compliance, focusing on newly founded firms. As a novelty the effect of tax authorities’ supervision on timely tax payments is examined. Interestingly, results show no positive overall effect of close supervision on tax compliance.

Legal enforcement of bans on goods can reduce the size of the black market but lead to greater violence by increasing revenue in the illicit market. However, the link between enforcement and violence is not as simple as is suggested by the textbook model, even for a competitive market....

Marginal deterrence concerns the incentives created by criminal penalties for offenders to refrain from committing more harmful acts. We show that when offenders act sequentially, it is often optimal for the level of the sanction, not just the expected sanction, to rise with the severity of the...

One can restructure institutions, but if individual-level motivations for corrupt behavior are not understood, these restructuring may not be effective. We introduce an evolutionary-game modeling to deal with the problem of corruption driven by imitative behavior.

I present a simple model of collusion in which the competition authority offers leniency rates contingent on the number of firms that report information. The optimal leniency policy involves what I refer to as a single informant rule—that is, leniency should be given only when a single firm...

This paper considers the effect of agrarian reforms on rioting in India. I find that the adoption of agrarian reforms was associated with a decline in the overall riot rate but the Hindu–Muslim riot rate, an urban phenomenon was largely unaffected by the program.
