This paper examines the identity and origins of Swedish inventors prior to WWI, 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 upper-tail of the economic, educational, and social status distribution. Analyzing children’s opportunities to become inventors, we show that inventors were disproportionately drawn from privileged family backgrounds. However, innovation was a path to upward mobility for the middle- and working-class children that managed to overcome the barriers to entry.

We use historical census data to show that Sweden exhibited high levels of intergenerational occupational mobility several decades before the rise of the welfare state. Mobility rates were higher than in other nineteenth- and twentieth-century European countries, closer to those observed in the highly mobile nineteenth-century United States. We leverage mobility variation across Swedish municipalities to shed light on potential determinants: economic growth and migration are positively correlated with mobility, consistent with the patterns observed across countries.
