This paper is the first to analyse the three-way relationship among money laundering, anti-money-laundering efforts and corruption. On the one hand, if we assume that the goal of criminals involved in corruption is to minimize the probability of being detected, then corruption represents a...

Local governments suspected of Mafia infiltration can be dismissed in Italy through an administrative act not increasing formal deterrence but potentially signaling improved law enforcement among local communities. This paper finds that dismissals are associated to a persistent fall of petty...

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...

In major legal orders such as UK, the U.S., Germany, and France, bribers and recipients face equally severe criminal sanctions. In contrast, countries like China, Russia, and Japan treat the briber more mildly. Given these differences between symmetric and asymmetric punishment regimes for...

To what extent, and under what conditions, does access to arms fuel violent crime? To answer this question, we exploit a unique natural experiment: the 2004 expiration of the U.S. Federal Assault Weapons Ban exerted a spillover on gun supply in Mexican municipios near Texas, Arizona and New...

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...

A random shock excludes reverse causality and reduces omitted variable bias. Yet a natural experiment does not identify random exposure to treatment, but the reaction to a random change from baseline to treatment. A lab experiment comparing higher certainty with higher severity of punishment for...

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 politicaleconomic...

In three distinct disciplines, crime and punishment are studied experimentally: in empirical legal studies, in experimental economics, and an experimental criminology. These three disciplines have surprisingly little interaction. The current paper surveys the rich evidence, and discusses the...

This paper examines the US gun-related murder (GM) rate and places it in an international context. The US GM rate is 27 times the average rate for 22 other developed countries (ODC). Its gun ownership rate is 5.4 times that of ODC and the murder rate per gun is 5 times that of ODC. Thus, as is...
