Project Description

Summary:  View help for Summary 
Despite the growing literature on the impact of immigration, little is known about the role existing migrant settlements can play for knowledge transmission and the location of industry. We present a case which can illustrate this important mechanism and hypothesize that nineteenth century Danish-American communities helped spread knowledge on modern dairying to rural America. From around 1880, Denmark developed rapidly and by 1890 it was a world-leading dairy producer. Using a difference-in-differences strategy, and data taken from the US census and Danish emigration archives, we find that counties with more Danes in 1880 subsequently both specialized in dairying and used more modern practices.
