In this paper, we examine how the labor market effects of an economic shock diffuse across space and sectors, and how these effects vary across individual characteristics and for migrants. We exploit the mining boom in Northern Sweden triggered by the unexpected increase in international resource prices in 2004, using geocoded individual-level administrative data and dynamic difference-in-differences specifications. We find consistent positive effects of the mining boom on earnings that extend up to 27 km from the mines during the first boom years and up to 83 km in subsequent years. We find particularly large gains in earnings and employment for residents directly employed in the mining sector, as well as significant positive earnings spillover effects in other sectors such as manufacturing, construction, and services. At the same time, the service sector experiences negative employment effects, consistent with a dominant resource movement effect relative to the local spending effect: the expanding mining sector draws workers away from other activities in a context of limited local labor supply. Finally, we find significant in-migration of young, unmarried, and highly educated individuals to mining areas, who benefit from the boom in terms of earnings and employment; this is especially true for migrants who relocate to work directly in the mining sector. • We study labor market effects of the 2004 mining boom in Northern Sweden. • Earnings gains spread up to 27 km from the mines initially and up to 83 km in later years. • The mining sector sees especially large and persistent gains in jobs and earnings. • The service sector experiences significant earnings gains but employment losses. • In-migrants are young, skilled, and experience large labor market gains.
