Researchers are often interested in estimating the causal effect of some treatment on individual criminality. For example, two recent relatively prominent papers have attempted to estimate the respective direct effects of marriage and gang participation on individual criminal activity. One...

In this paper we test for the theory of deterrence. We exploit the natural experiment provided by the Collective Clemency Bill passed by the Italian Parliament in July 2006. As a consequence of the provisions of the bill, expected punishment to former inmates recommitting a crime can be...

Our study is based on the traditional Becker-Ehrlich deterrence model, but we analyse the model in the face of currently discussed factors of crime like demographic changes, youth-unemployment and income inequality. We use a panel of the German Laender (states) that allows us to exploit...

We review current methods for calculating fines against cartels in the US and EU, and simulate their deterrence effects under different assumptions on the legal and economic environment. It is likely that European fines have not had significant deterrence effects before leniency programs were...

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 analyze optimal policy design when firms' research activity may lead to socially harmful innovations. Public intervention, affecting the expected profitability of innovation, may both thwart the incentives to undertake research (average deterrence) and guide the use to which innovation is put...

We analyse an oligopoly model in which differentiated criminal organizations compete on criminal activities and engage in corruption to avoid punishment. When law enforcers are sufficiently well-paid, difficult to bribe and corruption detection highly probable, we show that increasing policing...

We estimate the "incapacitation effect" on crime using variation in Italian prison population driven by eight collective pardons passed between 1962 and 1995. The prison releases are sudden – within one day –, very large – up to 35 percent of the entire prison population – and happen...

The paper provides new insights into the productivity of teams and the relationship between the inspector and the inspected party. Exploiting exogenous variation in the number of inspectors that are sent to offshore oil and gas platforms in the Gulf of Mexico, we find that adding an inspector...

An antitrust authority deters collusion using fines and a leniency program. Unlike in most of the earlier literature, our firms have imperfect cumulative evidence of the collusion. That is, cartel conviction is not automatic if one firm reports: reporting makes conviction only more likely, the...
