數量經濟與金融系列講座第401期：Infant Mortality and the Repeal of Federal Prohibition

Abstract: Federal prohibition from 1920 to 1933 was one of the most ambitious policy interventions in US history. Due to the political concessions necessary to bring about repeal, the removal of restrictions on alcohol after federal prohibition was not monolithic and instead evolved differently across counties and years. Exploiting new data on county-level variation in alcohol prohibition from 1933 to 1939, we investigate whether the repeal of federal prohibition increased infant mortality, both in counties and states that repealed and in their neighboring counties. We find that repeal is associated with a 4.0% increase in infant mortality rates in counties that chose wet status via local option elections or state-wide legislation and with a 4.7% increase in neighboring dry counties, suggesting a large role for cross-border policy externalities. These estimates imply that roughly 27,000 excess infant deaths could be attributed to the repeal of federal prohibition in this period.
