Empirical evidence on the causes and effects of inequality suggests the existence of a vicious circle of mutually reinforcing inequality and corruption. Despite the broad empirical evidence, there are only a few formal theoretical models on these dynamics. Relying on a game-theoretic approach,...

When Legislators introduce laws that award amnesties to 'low-rank' criminals co- operating with the justice, top criminals may bribe public officials to subvert the law. Legislators should anticipate this reaction and fight it back by introducing policies that bundle amnesties for low-rank...

Can machine learning support better governance? In the context of Brazilian municipalities, 2001-2012, we have access to detailed accounts of local budgets and audit data on the associated fiscal corruption. Using the budget variables as predictors, we train a tree-based gradient-boosted...

This article analyzes how law enforcers (with particular emphasis on securities regulators) should allocate their limited resources among multiple targets, as well as how they are likely to allocate these resources. It modifies existing models in one significant way: it considers the effect of...

Most normative studies on child labor arrive at the conclusion that child labor is detrimental to social welfare. Child labor is, however, still prevalent in many developing countries even though in many of these countries it is forbidden by law. In this paper we develop a political-economic...

There exists a large literature on the optimal deterrence of crime. Within the literature, however, there exists a controversy over what the appropriate criterion is to determine optimality. The most popular method is that of maximization of a utilitarian welfare function. The controversy stems...

The standard model of optimal deterrence predicts that the probability of wrongful conviction of innocents is at the margin as detrimental to deterrence as the wrongful acquittal of guilty individuals. We extend the model in several directions: using expected utility as well as non expected...

The burden of proof is a central feature of adjudication, and analogues exist in many other settings. It constitutes an important but largely unappreciated policy instrument that interacts with the level of enforcement effort and magnitude of sanctions in controlling harmful activity. Models are...

We analyze corruption in law enforcement: the payment of bribes to enforcement agents, threats to frame innocent individuals in order to extort money from them, and the actual framing of innocent individuals. Bribery, extortion, and framing reduce deterrence and are thus worth discouraging....
