For a rational choice theorist, the absence of crime is more difficult to explain than its presence. Arguably, the expected value of criminal sanctions, i.e. the product of severity times certainty, is often below the expected benefit. We rely on a standard theory from behavioral economics,...

This paper estimates the effect of a rehabilitative punishment on the post-release outcomes of juvenile criminals using a unique Finnish data set on sentences and punishments merged with the longitudinal population census for 1990-2007. The rehabilitative program was aimed at improving the...

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 describe the evolution of selective aspects of punishment in the United States over the period 1980–2004. We note that imprisonment increased around 1980, a period that coincides with the ‘‘Reagan revolution'' in economic matters. We build an economic model where beliefs about economic...

Are juvenile offenders deterred by criminal sanctions? Existing research indicates that they are not, as offending decreases only marginally when individuals cross the age of criminal majority and begin to face harsher, adult-level sanctions. Dynamic models of criminal behavior predict, however,...

I conduct a series of tests of peer influence in juvenile incarceration facilities motivated by three mechanisms: criminal skill transfer, the formation of new criminal networks, and the social contagion of crime-oriented non-cognitive factors. Identifying peer influence off natural variation in...
