We use individual-level income data from archived taxation lists to study top-income earners in Sweden from 1909 to 1950. Using information on 21,055 individual taxpayers in two elite areas in greater Stockholm, we show that top incomes fell in real terms over this period, at a stable pace without obvious connection to the Great Depression or the world wars. The peak of inequality was related to the early stages of a globalized economy with Schumpeterian entrepreneurial profits; the decline was related to sharpened competition, driving down profits, as well as increased regulation, expansion of education, and eroded position of professionals.

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.

Will technical change spur conflicts in the labor market? In this study, we examine electricity adoption in Sweden during the first decades of the twentieth century. Exploiting that proximity to hydropowered plants shaped the electricity network independently of previous local conditions, we estimate the impact of electricity on labor strikes. Our results indicate that electricity adoption preceded an increase in conflicts, but strikes were of an offensive nature and most common in sectors with increasing labor demand. This suggests that electrification provided workers with a stronger bargaining position from which they could voice their claims.

Using new and uniquely detailed data, we examine how construction workers’ wages in Sweden developed between 1831 and 1900. Wages grew rapidly from the 1850s, and comparisons with Northwestern Europe show that Swedish workers benefited more from growth than workers elsewhere. Globalization forces, most notably overseas migration, in combination with flexible and well-integrated labor markets—signified by strong regional convergence, falling skill differentials, and small urban-rural wage gaps—pushed up wages in Sweden.
