摘要：In 2007, 22 Wake County, North Carolina traditional calendar schools were switched to year-round calendars, spreading the 180 instructional days evenly across the year. This paper presents a human capital model to illustrate the conditions under which these calendars might affect achievement. We then exploit the natural experiment to evaluate the impact of year-round schooling on student achievement using a multi-level fixed effects model. Results suggest that year-round schooling has essentia...

摘要：We develop a simple model of trade relations in which legislators with different stakes in import-competing and export industries decide whether to grant fast-track authority (FTA) to the president, giving up the power to amend international trade agreements. We show that strategic delegation motives are key to understanding FTA votes, which involve a decision between alternative country representatives: the executive or the majority in Congress. We then examine the determinants of all votes b...

摘要：This paper investigates competition between jurisdictions in the context of cross-border shopping for state lottery tickets. Our theoretical model, in which consumers consider both travel costs and lottery payoffs, predicts that per-resident sales should be more responsive to prices in small states with densely populated borders. Using weekly sales data from US lotteries and drawing identification from the roll-over feature of jackpots, we estimate this responsiveness and find large effects th...

摘要：Estimates of moral hazard in health insurance markets can be confounded by adverse selection. This paper considers a plausibly exogenous source of variation in insurance coverage for childbirth in California. We find that additional health insurance coverage induces substantial extensions in length of hospital stay for mother and newborn. However, remaining in the hospital longer has no effect on readmissions or mortality, and the estimates are precise. Our results suggest that for uncomplicat...

摘要：Recent sleep research finds that many adolescents are sleep-deprived because of both early school start times and changing sleep patterns during the teen years. This study identifies the causal effect of school start time on academic achievement by using two policy changes in the daily schedule at the US Air Force Academy along with the randomized placement of freshman students to courses and instructors. Results show that starting the school day 50 minutes later has a significant positive eff...

摘要：Public-place smoking restrictions are the most important non-price tobacco control measures worldwide, yet surprisingly little is known about their effects on exposure to environmental tobacco smoke (ETS). We study these laws in Canada using data with questions about respondents' ETS exposure in public and private places. In fixed effects models we find these laws had no effects on smoking but induced large and statistically significant reductions in public-place ETS exposure, especially in ba...

摘要：Theory predicts that the majoritarian electoral system should produce more targeted redistribution and lower rents than proportional representation. We test these predictions using data on the Italian House of Representatives, and address the nonrandom selection into different systems exploiting one feature of the two-tier elections between 1994-2001: candidates could run for both the majoritarian and proportional tier, but if they won in both they had to accept the majoritarian seat. Focusing...

摘要：With heterogeneity in both skills and discount factors, the Atkinson-Stiglitz theorem that savings should not be taxed does not hold. In a model with heterogeneity of preferences at each earnings level, introducing a savings tax on high earners or a savings subsidy on low earners increases welfare, regardless of the correlation between ability and discount factor. Extending Emmanuel Saez (2002), a uniform savings tax increases welfare if that correlation is sufficiently high. Key for the resul...

摘要：This paper uses a within-school/across-cohort design to present new evidence of the effects of high school classmate characteristics on a wide range of post-secondary outcomes. We find that increases in the percent of classmates with college-educated mothers decreases the likelihood of dropping out and increases the likelihood of attending college, despite showing no impact on a range of in-school achievement, attitudes, and behaviors. The percent of students from disadvantaged minority groups...

摘要：Within metropolitan areas, neighborhoods of growing immigrant settlement are becoming relatively less desirable to natives. We deploy a geographic diffusion model to instrument for the growth of immigrant density in a neighborhood. Our approach deals explicitly with potential unobservable shocks that may be correlated with proximity to immigrant enclaves. The evidence is consistent with a causal interpretation of an impact from growing immigrant density to native flight and relatively slower h...
