We examine impacts of market integration on the development of American manufacturing, as railroads expanded through the latter half of the 19th century. Using new county-by-industry data from the Census of Manufactures, we estimate substantial impacts on manufacturing productivity from relative...

This paper examines the historical impact of railroads on the American economy. Expansion of the railroad network may have affected all counties directly or indirectly - an econometric challenge that arises in many empirical settings. However, the total impact on each county is captured by...

We characterize female-owned manufacturing establishments using newly digitized manuscripts from the US Census of Manufactures (1850, 1860, 1870, 1880). Female-owned establishments were smaller than male-owned establishments and had lower capital-to-output ratios, which could reflect...

We examine "agglomeration shadows" that emerge around large cities, which discourage some economic activities in nearby areas. Identifying agglomeration shadows is complicated, however, by endogenous city formation and "wave interference" that we show in simulations. We use the locations of...

We re-characterize American slavery as inefficient, whereby emancipation generated substantial aggregate economic gains. Coercive labor markets were severely distorted, with the social marginal cost of labor substantially above its marginal benefit. Production during enslavement came at immense...

We examine the long transition from water to steam power in US manufacturing, focusing on early users of mechanical power: lumber and flour mills. Digitizing Census of Manufactures manuscripts for 1850 to 1880, we show that as steam costs declined, manufacturing activity grew faster in counties...
