This paper estimates the elasticity of substitution between capital and skill using variation across U.S. counties in immigration-induced skill-mix changes between 1860 and 1930. We find that capital began as a q-complement for skilled and unskilled workers, and then dramatically increased its...

A number of conceptually robust and empirically practical approaches are available to assess relative economic performance among producers who operate on either side of an international border. In this paper we discuss the impact that data compilation, methodological choice, and variable...

This paper develops a model of firm heterogeneity, technological adoption, and urbanization. In the model, welfare is measured by household real income, and urbanization is measured by population density. I use the model to derive statistics that measure the effect of a new technology on...

This paper assesses the causal impact of greater market access on demographic transition during the latter half of the 19th century in the United States. We construct new measures of fertility changes and measures of railroad access at the county level from 1850 – 1890. We are able to document...

Alternative measures for material conditions are frequently used to evaluate economic welfare during development. The basal metabolic rate and calories are two alternative net nutrition measures that vary by demographics, nativity, residence, and socioeconomic status. During the 19th and early...

When traditional measures for income and wealth are scarce or unreliable, alternative values are effective in measuring nutritional conditions during economic development. This study uses net nutrition and calories to illustrate that during the 19th and early 20th centuries that men required...

The European Marriage Pattern (EMP), in place in NW Europe for perhaps 500 years, substantially limited fertility. But how could such limitation persist when some individuals who deviated from the EMP norm had more children? If their children inherited their deviant behaviors, their descendants...

This paper presents insights on U.S. business cycle volatility since 1867 de- rived from diffusion indices. We employ a Bayesian dynamic factor model to obtain aggregate and sectoral economic activity indices. We find a remarkable increase in volatility across World War I, which is reversed...

Recent modern life expectancy improvements rely heavily on medical intervention; however, before the mid-20th century, increased longevity was primarily the result of improved nutrition and less virulent disease environments. Moreover, 19th century health conditions varied by race, especially in...

The ongoing process of European integration is likely to increase trade and factor mobility thereby increasing interregional competition and affecting the interregional division of labor. From a theoretical standpoint, rising specialization and polarization of European regions may result from...
