Agriculture on the American Plains has been constrained historically by water scarcity. Post-WWII technologies enabled farmers over the Ogallala aquifer to extract groundwater for large-scale irrigation. Comparing counties over the Ogallala with nearby similar counties, groundwater access...

We use the introduction of a means-tested voucher program in Florida to examine whether increased competitive pressure on public schools affects students' test scores. We find greater score improvements in the wake of the program introduction for students attending schools that faced more...

This paper estimates the overall impact and externality effects of an influenza vaccination program expanding coverage outside the typical target group. Using a triple-difference design, which exploits the introduction of a broad based vaccination program in Ontario and the quality of the...

We use the Swedish compulsory school reform to estimate the causal effect of parental education on sons' outcomes. To this end, we use data from the Swedish military enlistment register on the entire population of males and consider outcomes, such as cognitive skills, noncognitive skills, and...

The onset of World War I spurred the "Great Migration" of African Americans from the US South, arguably the most important internal migration in US history. We create a new panel dataset of more than 5,000 men matched from the 1910 to 1930 census manuscripts to address three interconnected...

This paper analyzes Thailand's 2001 healthcare reform, "30 Baht." The program increased funding available to hospitals to care for the poor and reduced copays to 30 Baht (~$0.75). Our estimates suggest the supply-side funding of the program increased healthcare utilization, especially among the...

This paper presents evidence on the perverse trade-off that first price auctions induce between low prices at the awarding stage and poor ex post performance when bids are not binding commitments. By exploiting the different timing with which first price auctions were introduced in Italy to...

The most desirable Kenyan secondary schools are elite government schools that admit the best students from across the country. We exploit the random variation generated by the centralized school admissions process in a regression discontinuity design to obtain causal estimates of the effects of...

This paper uses data from three prominent exam high schools in New York City to estimate the impact of attending a school with high-achieving peers on college enrollment and graduation. Our identification strategy exploits sharp discontinuities in the admissions process. Applicants just eligible...
