Does the death penalty save lives? A surge of recent interest in this question has yielded a series of papers purporting to show robust and precise estimates of a substantial deterrent effect of capital punishment. We assess the various approaches that have been used in this literature, testing...

We investigate the determinants of the support for cannabis legalization finding a causal effect of personal experience with cannabis use. Current and past cannabis users are more in favor of legalization. We relate this to self-interest and inside information about potential dangers of cannabis...

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 develop an agency model of organized crime accounting for the main trade-offs involved by the introduction of an accomplice-witness program. We characterize the optimal policy and identify its main determinants in a framework where public officials can be dishonest. Our predictions are tested...

In a model in which firms can go bankrupt because of adverse market shocks or antitrust fines, we find that even large corporate fines may not be able to induce deterrence. Managerial penalties are thus needed. If the policy may be changed according to the state of the business cycle, then the...

Wealthy individuals often voluntarily provide public goods that the poor also consume. Such philanthropy is perceived as legitimizing one’s wealth. Governments routinely exempt the rich from taxation on grounds of their charitable expenditure. We examine the normative logic of this exemption....

Efficient measures are often not implemented because of their potentially damaging effects on distribution, yet these distributional effects are scarcely studied in economics because of the idea that they are case specific. In this paper we show that when we can separate the effect on efficiency...

We propose a market-for-offenses model of property crime, which explicitly accounts for protection expenditures among heterogeneous individuals. The crime equilibrium is modeled as a free-access equilibrium in which the match between criminals and victims equates the average returns to crime. We...

In this paper we focus on the implications of consumer heterogeneity for whether competition will improve outcomes in health care markets. We show that competition generally favours the majority group as higher quality for the majority is an effective way to increase the quality signal and...

The impact of various facets of cultural diversity on economic outcomes has become a topic of intensive research in economics. This paper focuses on linguistic diversity as one of the important aspects of cultural heterogeneity, and more specifically, The aim of this paper is to formally examine...
