摘要：In difference-in-differences applications, identification of the key parameter often arises from changes in policy by a small number of groups. In contrast, typical inference assumes that the number of groups changing policy is large. We present an alternative inference approach for a small (finite) number of policy changers, using information from a large sample of nonchanging groups. Treatment effect point estimators are not consistent, but we can consistently estimate their asymptotic distr...

摘要：Are price and consumption independent in flat-rate price service contexts? A field experiment at an all-you-can-eat pizza restaurant shows that a 50% discount on the price of the meal led customers to consume 27.9% less pizza (2.95 versus 4.09 pieces). A second analysis indicated that individual taste ratings of this pizza tended to be inversely related to how much is consumed. One possible interpretation of these two findings is that individuals in a flat-rate (or fixed-price) context may con...

摘要：Since recent immigrants tend to earn less than natives, their relative earnings have been adversely affected by an increase in the return to labor market skills over the past three decades. Using longitudinal Social Security records matched to cross-sections of the SIPP and CPS, I estimate the return to skills rose by 41% between 1980 and 1997. This reduced the relative earnings of immigrants who arrived in the 1980s and early 1990s by 10 to 15 percentage points. Examining solely the earnings ...

摘要：Does hiring workers with experience from multinationals (MNEs) increase productivity in non-MNEs? Tracing worker flows between plants in Norwegian manufacturing during the 1990s, I find a positive correlation between the share of workers with MNE experience in non-MNEs and the productivity of these plants. Workers with MNE experience contribute 20% more to the productivity of their plant than workers without such experience, even after controlling for differences in unobservable worker charact...

摘要：This paper investigates how dividend taxes influence portfolio choices, using the response to the distinctive treatment of a subset of foreign dividends in the Jobs and Growth Tax Relief Reconciliation Act (JGTRRA) of 2003. An open-economy after-tax capital asset pricing model is used to derive the hypothesis that JGTRRA should lead to a portfolio reallocation by U.S. investors toward equities in tax-favored countries. A difference-in-difference analysis that compares U.S. equity holdings in a...

摘要：This paper examines the extent to which Mexican emigrants to the United States are negatively selected. Previous studies have been limited by the lack of nationally representative longitudinal data. This one uses a newly available household survey, that identifies emigrants before they leave. On average, U.S.-bound Mexican emigrants from 2000 to 2004 earn lower wages and have less (more for females) schooling than nonmigrant Mexicans, evidence of negative selection. This argues against Chiquia...

摘要：Road safety policies often use incentive mechanisms based on traffic violations to promote safe driving-for example, fines, experience rating, and point-record driver's licenses. We analyze the effectiveness of these mechanisms in promoting safe driving. We derive their theoretical properties with respect to contract time and accumulated demerit points. These properties are tested empirically with data from the Quebec public insurance plan. We find evidence of moral hazard, which means that dr...

摘要：We estimate the impact of market development and democratization on subjective political preferences. We rely on the specific situation of frontier zones and the considerable regional variations in culture and economic development in the countries of the former socialist bloc for identification. Using a survey conducted in 2006, we find a positive and significant effect of democracy on support for a market economy, but no effect of market liberalization on support for democracy. Hence, in cont...
