We analyze investment decisions when information is costly, with and without delegation to an agent. We use a rational-inattention model and compare it with a canonical signal-extraction model. We identify three "investment conditions". In "sour" conditions, no information is acquired and no...

The net-zero agreement on carbon emission from Paris 2015 gives a key role to fossil-free energy technologies with an expected multifold growth rate over the coming decades, when successively replacing oil, coal, and gas. In this paper, we delve into the EU's competitive advantage in the...

This paper studies social-tie formation when individuals care about the geographical location of other individuals. In our model, the intensity of social interactions can be chosen at the same time as friends. We characterize the equilibrium in terms of both social interactions and social...

Using longitudinal Swedish data, we document robust evidence of highly local spillovers between individuals in similar occupations. The results are consistent with the existence of knowledge spillovers between workers performing similar work tasks in the same city-district. We further...

We estimate the direct and spillover effects of a large-scale early childhood intervention on the educational attainment of over 2,000 disadvantaged children in the United States. We show that failing to account for spillover effects results in a severe underestimation of the impact. The...

Is technology or trade driving increases in wage inequality? We propose that technology interacts with trade in the form of foreign direct investments to widen domestic wage inequality. We show that foreign acquisitions of domestic firms disproportionately affect wages for workers who perform...

The relevance of residential segregation and ethnic enclaves for labor market sorting of immigrants has been investigated by a large body of literature. Previous literature presents competing arguments and mixed results for the effects of segregation and ethnic concentration on various labor...

The rapid rise of e-scooters (electric scooters) in cities around the world, boosted by the introduction of shared e-scooter services has visibly reshaped the way people move around cities, sparking both excitement and controversy. With the increase in popularity of these vehicles, concerns...

This paper examines the electoral impact of increased foreign tourism, using data from Croatia. Exploiting exogenous variation in travel times to coastal municipalities from improved road infrastructure, I show that foreign tourism reduces nationalist voting and increases the center-left vote...

Mission-oriented innovation policies are becoming increasingly popular among policymakers and scholars. We maintain that these policies are based on an overly mechanistic view of innovation and economic growth, suggesting that a more bottom-up approach is called for. By invoking an...
