摘要：We exploit exogenous variation in legal status following the January 2007 European Union enlargement to estimate its effect on immigrant crime. We difference out unobserved time-varying factors by (i) comparing recidivism rates of immigrants from the new and candidate member countries; and (ii) using arrest data on foreign detainees released upon a mass clemency that occurred in Italy in August 2006. The timing of the two events allows us to setup a difference-in-differences strategy. Legal st...

摘要：We study how media environments interact with political institutions that structure the accountability of public officials. Specifically, we quantify media influence on the behavior of US state court judges. We analyze around 1.5 million criminal sentencing decisions from 1986 to 2006 and new data on the newspaper coverage of 9,828 trial court judges. Since newspaper coverage is endogenous, we use the match between newspaper markets and judicial districts to identify effects. We find that news...

摘要：Using comprehensive administrative data on France's single largest financial aid program, this paper provides new evidence on the impact of large-scale need-based grant programs on the college enrollment decisions, persistence, and graduation rates of - low-income students. We exploit sharp discontinuities in the grant eligibility formula to identify the impact of aid on student outcomes at different levels of study. We find that the provision of 1,500 euros cash allowances to prospective unde...

摘要：We analyze data from a field experiment in which an auto repair firm provided checklists to mechanics and monitored their use. Revenue was 20 percent higher during the experiment, and the effect is equivalent to that of a 1.6 percentage point (10 percent) commission increase. Checklists appear to boost productivity by serving both as a memory aid and a monitoring technology. Despite the large benefits to the firm, mechanics did not use checklists without the firm directly monitoring their use....

摘要：Community-rating regulations equalize the insurance premiums faced by the healthy and the unhealthy. Intended reductions in the unhealthy's premiums can be undone, however, if the healthy forgo coverage. The severity of this adverse selection problem hinges largely on how health care costs are distributed across market participants. Theoretically, I show that Medicaid expansions can combat adverse selection by removing high cost individuals from the relevant risk pool. Empirically, I find that...
