We examine the effect of the Amnesty Plus policy on firms’ incentives to engage in cartel activities. Amnesty Plus is a proactive antitrust enforcement strategy aimed at attracting amnesty applications by encouraging firms already convicted in one market to report collusive agreements in other markets. It has been heavily advertised that Amnesty Plus weakens cartel stability. We show to the con...

Patches to modern operating systems, including bug fixes and security updates, and the reboots and downtime they require, cause tremendous problems for system users and administrators. Dynamic update allows an operating system to be patched without the need for a reboot or other service interruption. We have taken the approach of building dynamic update functionality directly into an existing o...

This paper investigates whether and to what extent there is a conflict of interest between artists and their publishers, regarding to whether and to what degree illegal distributions of their copyrighted recordings should be prevented. This conflict arises because artists also earn their profit from other market activities such as giving live performances, in addition to their share of profits ...

Patches to modern operating systems, including bug fixes and security updates, and the reboots and downtime they require, cause tremendous problems for system users and administrators. The aim of this research is to develop a model for dynamic update of operating systems, allowing a system to be patched without the need for a reboot or other service interruption. In this work, a model for dynam...

Parallel shared-memory software must control concurrent access to shared resources. This is typically accomplished via locking designs that result in low concurrency or that are highly complex. This paper presents two-phase update, which is an alternative method of updating concurrent data structures, and demonstrates that it is both simple and highly scalable in restricted but commonly occurri...

We estimate the causal effect of mandatory participation in the military service on the involvement in criminal activities. We exploit the random assignment of young men to military service in Argentina through a draft lottery to identify this causal effect. Using a unique set of administrative data that includes draft eligibility, participation in the military service, and criminal records, we...

This paper empirically investigates three hypotheses regarding biases of National Basketball Association (NBA) referees. Using a sample of 28,388 quarter-level observations from six seasons, we find that referees make calls that favor home teams, teams losing during games, and teams losing in playoff series. All three biases are likely to increase league revenues. In order to distinguish betwee...

In August 2006, the Italian government released one-third of the nation’s prison inmates via a national collective pardon. We test for a discontinuous break in national crime rates corresponding to the mass release. We also test for the effect of the return of the incarceration rate to its predicted steady state level on national crime rates. Finally, we exploit regional variation in prison rel...

Successes of law enforcement in apprehending offenders are often publicized events. Such events have been found to result in temporary reductions in offending, or “residual deterrence”. We provide a theory of residual deterrence which accounts for the incentives of both enforcement officials and potential offenders. Our theory rests on the costs of reallocating enforcement resources. In light o...
