We exploit exogenous variation arising from the historical rollout of the Swedish railroad network across municipalities to identify the impacts of lowered interaction costs on innovative activity. A network connection led to a surge in local innovation due to an increased entry, productivity,...

This paper studies the effect of emigration on technological change in sending locations after one of the largest migration events in human history, the mass migration from Europe to the United States in the 19th century. To establish causality, we adopt an instrumental variable strategy that...

This paper examines the identity and origins of Swedish inventors prior to World War I drawing on the universe of patent records linked to census data. We document that the rise of innovation during Sweden's industrialization can largely be attributed to a small industrial elite belonging to the...
