How much does the current social security system really redistribute from rich to poor? We use the PSID to estimate lifetime wage profiles and actual earnings each year for a sample of 1778 individuals, and we use mortality probabilities to calculate expected payroll taxes and social security...

Building on the existing literature that examines the extent of redistribution in the Social Security system as a whole, this paper focuses more specifically on how Social Security affects the poor. This question is important because a Social Security program that reduces overall inequality by...

This paper examines the welfare consequences of changing the current U.S. income tax system to a progressive consumption tax. We compute a sequence of single period equilibria in which savings decisions depend on the expected future return to capital. In the presence of existing income taxes,...

I study the impact of transportation on health in the rural US, 1820-1847. Measuring health by average stature, I find that greater transportation linkage, as measured by market access, in a cohort's county-year of birth had an adverse impact on its health. A one-standard deviation increase in...

After adjusting for sample-selection bias, I find a net decline in average stature of 0.64 inches in the birth cohorts of 1832--1860 in the US. This result supports the veracity of the Antebellum Puzzle--a deterioration of health during early modern economic growth in the US. However, this...

Immigrant distribution--the geographic dispersion of immigrants in the destination country--was a major issue in the United States in the late Age of Mass Migration. Policy debates were influenced by the widely held view that the new immigrants were generally less geographically mobile within...

Why were the poorer countries of the European periphery latecomers to the Age of Mass Migration? We test the diffusion hypothesis, which argues that mass emigration was delayed because it was primarily governed by a gradual process of spatial diffusion of migration networks. We propose a model...

I study the internal migration of native-born white men in the United States using linked census data covering all possible 10- and 20-year periods 1850--1940. Inter-county migration rates were stable over time. Selection into migration on the basis of occupational status was also largely stable...
