摘要：Citation indices are regularly used to inform critical decisions about promotion, tenure, and the allocation of billions of research dollars. Nevertheless, most indices (e.g., the h-index) are motivated by intuition and rules of thumb, resulting in undesirable conclusions. In contrast, five natural properties lead us to a unique new index, the Euclidean index, that avoids several shortcomings of the h-index and its successors. The Euclidean index is simply the Euclidean length of an individual...

摘要：This paper presents empirical evidence that the growth of export manufacturing in Mexico during a period of major trade reforms (the years 1986 to 2000) altered the distribution of education. I use variation in the timing of factory openings across commuting zones to show that school drop-out increased with local expansions in export-manufacturing industries. The magnitudes I find suggest that for every 25 jobs created, one student dropped out of school at grade 9 rather than continuing throug...

摘要：We examine differences in minority science graduation rates among University of California campuses when racial preferences were in place. Less prepared minorities at higher ranked campuses had lower persistence rates in science and took longer to graduate. We estimate a model of students' college major choice where net returns of a science major differ across campuses and student preparation. We find less prepared minority students at top ranked campuses would have higher science graduation r...

摘要：Lincoln's election produced Southern secession, war, and abolition. Using a new dataset on slave sales, we examine connections between news and slave prices for the period 1856-1861. By August 1861, slave prices had declined by roughly one-third from their 1860 peak. That decline was similar for all age and sex cohorts and thus did not reflect expected emancipation without compensation. The decision to secede reflected beliefs that the North would not invade and that emancipation without compe...

摘要：We combine a theoretical discrete-choice model of vehicle purchases, an econometric analysis of electricity emissions, and the AP2 air pollution model to estimate the geographic variation in the environmental benefits from driving electric vehicles. The second-best electric vehicle purchase subsidy ranges from $2,785 in California to -$4,964 in North. Dakota, with, a mean of -$1,095. Ninety percent of local environmental externalities from driving electric vehicles in one state are exported to...

摘要：This paper exploits quasi-experimental variation in tariffs in southern Africa to estimate trade elasticities. Traded quantities respond only weakly to a 30 percent reduction in the average nominal tariff rate. Trade flow data combined with primary data on firm behavior and bribe payments suggest that corruption is a potential explanation for the observed low elasticities. In contexts of pervasive corruption, even small bribes can significantly reduce tariffs, making tariff liberalization sche...
