We examine the impact of political reservation for disadvantaged minority groups on poverty. To address the concern that political reservation is endogenous, we take advantage of the state-time variation in reservation in state legislative assemblies in India generated by national policies that cause reservations to be revised and the time lags with which revised reservations are implemented. Using data on sixteen major Indian states for the period 1960-2000, we find that increasing the share of seats reserved for Scheduled Tribes significantly reduces poverty while increasing the share of seats reserved for Scheduled Castes has no impact on poverty. Political reservation for Scheduled Tribes has a greater effect on rural poverty than urban poverty, and appears to benefit people near the p...

Ten states, beginning with Texas and California in 2001, have passed laws permitting undocumented students to pay the in-state tuition rate – rather than the more expensive out-of-state tuition rate – at public universities and colleges. We exploit state-time variation in the passage of the laws to evaluate the effects of these laws on the educational outcomes of Hispanic childhood immigrants who are not U.S. citizens. Specifically, through the use of individual-level data from the 2001-2005 American Community Surveys supplemented by the 2000 U.S. Census, we estimate the effect of the laws on the probability of attending college for 18- to 24-year-olds who have a high school degree and the probability of dropping out of high school for 16- to 17-year-olds. We find some evidence suggestive ...

Between 1898 and 1948, English was the language of instruction for most post-primary grades in Puerto Rican public schools. Since 1949, the language of instruction in all grades has been Spanish. We use this policy change to estimate the effect of English-intensive instruction on the English-language skills of Puerto Ricans. Although naive estimates suggest that English instruction increased English-speaking ability among Puerto Rican natives, estimates that allow for education-specific cohort trends show no effect. This result is surprising in light of the strong presumption by American policymakers at the time that instruction in English was the best way to raise English proficiency. This has implications for medium of instruction policy in former colonies as well as U.S. education polic...

Using a large, individual-level wage data set, we examine the impact of a major technological innovation the steam engine on skill demand and the wage structure in the merchant shipping industry. We find that the technical change created a new demand for skilled workers, the engineers, while destroying demand for workers with skills relevant only to sail. It had a deskilling effect on production work able-bodied seamen (essentially, artisans) were replaced by unskilled engine room operatives. On the other hand, mates and able-bodied seamen employed on steam earned a premium relative to their counterparts on sail. A wholesale switch from sail to steam would increase the 90/10 wage ratio by 40%, with most of the rise in inequality coming from the creation of the engineer occupation.
