April 2017Infant Mortality and the Repeal of Federal Prohibition
with David S. Jacks, Hitoshi Shigeoka: w23372
Exploiting a newly constructed dataset on county-level variation in prohibition status from 1933 to 1939, this paper asks two questions: what were the effects of the repeal of federal prohibition on infant mortality? And were there any significant externalities from the individual policy choices of counties and states on their neighbors? We find that dry counties with at least one wet neighbor saw baseline infant mortality increase by roughly 3% while wet counties themselves saw baseline infant mortality increase by roughly 2%. Cumulating across the six years from 1934 to 1939, our results indicate an excess of 13,665 infant deaths that could be attributable to the repeal of federal prohibition in 1933.
June 2008Global Trade and the Maritime Transport Revolution
with David S. Jacks: w14139
What is the role of transport improvements in globalization? We argue that the nineteenth century is the ideal testing ground for this question: freight rates fell on average by 50% while global trade increased 400% from 1870 to 1913. We estimate the first indices of bilateral freight rates for the period and directly incorporate these into a standard gravity model. We also take the endogeneity of bilateral trade and freight rates seriously and propose an instrumental variables approach. The results are striking as we find no evidence that the maritime transport revolution was the primary driver of the late nineteenth century global trade boom. Rather, the most powerful forces driving the boom were those of income growth and convergence.
