Vote trading among lawmakers (logrolling) can enable political rent-seeking but is difficult to identify. To achieve identification, we explore the rules governing voting for railway projects in the U.K. Parliament during the Railway Mania of the 1840s. Parliamentary rules barred MPs from voting directly for their interests. Even so, they could trade votes to ensure their interests prevailed. We find that logrolling was significant, accounting for nearly one-quarter of the railway bills approved. We also quantify a negative externality to society from logrolling ranging from 1/3 to 1 percent of contemporary GDP.

We present quantitative evidence that the mita introduced by the Spanish crown in 1573 caused the decimation of the native-born male population. The mass baptisms after the conquest of Peru in 1532 resulted in the assignation of surnames for the first time. We argue that past mortality displacement and mass out-migration were responsible for differences in the surnames observed in mita and non-mita districts today. Using a regression discontinuity and data from the Peruvian Electoral Roll of 2011, we find that mita districts have 47 log points fewer surnames than non-mita districts, and fewer surnames exclusive to one location.

From 1580, the Jesuits introduced European sciences to China―an autarkic civilization whose intelligentsia was dominated by Confucian literati. Drawing upon prefectural distributions of the Jesuits and Chinese scientific works, this paper demonstrates that the Jesuits stimulated Confucian literati to study science. On average, the literati’s scientific works increased four times in prefectures with Jesuit scientists after 1580. But this effect shrank after the Jesuits were expelled by the emperor of China in 1723. Since China’s scholar-official system remained unchanged, the literati’s scientific research aimed to serve the needs of statecraft rather than translating into economic progress.

Cash-crop diffusion in colonial Africa was uneven and defied colonizers’ expectations and efforts, especially for cotton. This study investigates how agricultural seasonality affected African farmers’ cotton adoption, circa 1900–1960. A contrast between British Uganda and the interior of French West Africa demonstrates that a short rainy season and the resulting short farming cycles generated seasonal labor bottlenecks and food security concerns, limiting cotton output. Agricultural seasonality also had wider repercussions, for colonial coercion, investment, and African income-earning strategies. A labor productivity breakthrough in post-colonial Francophone West Africa mitigated the seasonality constraint, facilitating impressive cotton output growth post-1960.

After peaking around the mid-eighteenth century, grain market integration in China declined by a colossal 80 percent amid a twofold increase in population and remained at low levels for well over a century. Markets only resumed their growth momentum after the largest peasant revolt—the Taiping Rebellion—wiped out roughly one-sixth of the Chinese population starting 1851. This U-shaped pattern of grain market integration distinguished China from Europe in their trajectories of market development. Using grain prices to divide China into grain-deficit and grainsurplus regions, we find that the negative relationship between population growth and market integration originated from the grain-surplus-cum-exporting regions.

This study investigates the impact of malaria eradication programs on Black-white economic disparities in the early 1900s U.S. South. Malaria eradication was widespread and improved health across races. Yet, only white men experienced economic benefits. Using matched census records, we find that increased exposure to the program was associated with higher schooling attainment and income for whites but not for Blacks. Blacks exposed to malaria eradication were more likely to be farm laborers, and both Blacks and whites were more likely to migrate out of state. Our findings suggest that malaria eradication, a broadly applied intervention, widened racial gaps.

The 1944 Servicemen’s Readjustment Act (the “G.I. Bill”) provided returning WWII veterans with educational benefits sufficient to cover tuition, fees, and living expenses at almost any U.S. university or college. While several studies examine subsequent educational attainment and earnings for male veterans, little is known about how the G.I. Bill affected the 330,000 American females who served in WWII. Using data from the 1980 5 percent Census Public-use Microdata Sample, I find that female WWII veteran status is associated with a 19 percentage point increase in the proportion who report any college attendance, a 7.8 percentage point increase in college completion, and earnings that are 19.8 percent greater relative to comparable females who are not veterans. Because service was entirely voluntary for females, I use service eligibility requirements, enlistment records, 1940 Census data, and the G.I. Bill’s retroactive nature to establish a causal relationship among veteran status, educational attainment via the G.I. Bill, and increased earnings. To help separate the effect of the G.I. Bill from the effect of military service itself, and because benefits increased with longer service, I instrument for female veterans’ educational attainment using age at the time of the G.I. Bill’s announcement. My instrumental variables estimates imply that female veterans’ earnings increase by $1,350 (11.6 percent) per year of G.I. Bill-induced education, explaining 73 percent of the overall difference between veteran and non-veteran females’ earnings in 1980.
