- Using a highly comprehensive new data set on Swedish researchers, we investigate the effects of inter-university mobility on researcher productivity. Our study suggests substantial gains from mobility on scientific output. The empirical analysis addresses selection using inverse probability treatment censoring weights. We find that mobility induces a long-lasting increase in a researcher's publications by 32% and citations by 63%. Such mobility effects are not explained by promotions taking place jointly with a move. Positive effects are found among individuals who move between universities and not for those who move to or from university colleges. Moreover, we find that the positive effect of moving only applies to researchers in medicine, natural sciences and engineering and technology, with no effect of mobility found in the social sciences and in the humanities.

Home, Sweet Home: Returns to Returning in the Age of Mass Migration
- 2022
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Studying migrants from Sweden to the United States, we provide new evidence on return migration during the Age of Mass Migration. Focusing on a sample of migrants and stayers observed in childhood, we document limited effects on income and occupational upgrading, but large effects on wealth. Male returnees held about twice as much wealth as stayers and about 40 percent more than staying brothers. These effects were likely driven by accumulated savings overseas, rather than inheritance or an income premium back home. For female returnees, wealth effects are of similar magnitude, but appear to be realized primarily through marriage.

Innovation in Malmö after the Öresund Bridge
- 2022

Tidskriftsartikel (refereegranskat)abstract
- We analyze the effect of the Öresund Bridge, a combined railway and motorway bridge between Swedish Malmö and the Danish capital Copenhagen, on inventive activity in the region of Malmö. Applying difference-in-difference estimation on individual-level data, our findings suggest that the Öresund Bridge led to a significant increase in the number of patents per individual in the Malmö region as compared with the two other major regions in Sweden, Gothenburg, and Stockholm. We show that a key mechanism is the attraction of highly qualified workers to the Malmö region following the construction of the bridge.

When colleges graduate : Micro-level effects on publications and scientific organization

Tidskriftsartikel (refereegranskat)abstract
- We examine the change in status of three Swedish colleges to universities in 1999. This change greatly expanded the inflow of resources in the form of basic funding to the new universities. Using detailed individual data, we follow the careers of staff employed before 1999 at the treated institutions, examining their scientific performance, promotion, affiliation, and coauthorship behavior after the transition to university and comparing them to that of matched sample researchers at control colleges in a difference-in-differences analysis. We find an 89 percent increase in publication by publishing academics, an effect driven by increased funding. But we do not find an increased likelihood of publishing. Publication activity is concentrated among men, those working in technical sciences, and those holding research positions. The change to a university also led to a shift toward research-enhancing practices and organizations, manifested in coauthorship patterns, affiliations, and workforce composition. These changes altogether, enabled the new universities to begin converging in terms of research productivity to the level of established universities. Our results indicate that additional resources to institutions that historically received insufficient investment unlocked the research potential of aspiring researchers.

Drifting on the Academic Highway: Experimental Evidence from a Transition to University
- 2023

Konferensbidrag (refereegranskat)abstract
- We examine the effects of the 1999 transition to full university of three former Swedish university colleges: Karlstad, Örebro, and Växjö on scientific output. This change was accompanied by a substantial increase in research funding. Scrutiny of the process reveals that the transition was far from obvious, allowing us to analyze the impact of increased research resources in a quasi-experimental setting. We examine how publications responded when research resources were raised from low levels. We then probe into the consequences on the individual level to understand the difference in gains between staff groups. This work differs from earlier research which has mostly looked at the effects of increases in research funding on established universities or individuals who win research grants. To understand how the transition impacted publication, we use an individual-level publication activity dataset, linked to Swedish register data and university staff registers. We contrast the three treated institutions against a similar group of university colleges that did not become universities in a difference-in-differences analysis combined with matching. We find that treated individual increased their publication rates by 89% per year following the transition. However, we cannot discern any changes in the rate at which publications were cited. On the field level, we show that this effect was mostly explained by increased funding. Additionally, we explore the heterogeneity of treatment effects, potential mechanisms (collaboration, workforce dynamics), and management strategies (using a survey).
