We survey the literature on the economic consequences of the structure of social networks. We develop a taxonomy of "macro" and "micro" characteristics of social interaction networks and discuss both the theoretical and empirical findings concerning the role of those characteristics in...

Although the linear-in-means model is the workhorse model in empirical work on peer effects, its theoretical properties are understudied. In this study, we develop a social-norm model that provides a micro foundation of the linear-in-means model and investigate its properties. We show that...

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...

We explore the effects of neighborhood-level ethnic enclaves on the propensity of immigrants to use business ownership as a vehicle to transcend from labor market outsiders to insiders. We exploit an exogenously partitioned grid of geocoded 1-by-1 km squares to approximate neighborhoods, and...

We test whether people's tendency to stick with the default option can help save resources. In a natural field experiment we switch printers' default settings, from simplex to duplex printing, at a large Swedish university. The results confirm that roughly one third of all printing is determined...

We examine immigrant self-employment in Sweden during 2011-2021 - a turbulent decade with a large influx of refugees into the country and the outbreak of the global COVID-19 pandemic. Four outcome variables are investigated: the probability of self-employment, the probability of entry into and...

In this paper, we use a randomized field experiment in Sweden to investigate how self-employment experience is valued in the labor market. We find that self-employment experience negatively impacts the probability of receiving a positive response from employers. For male applicants, this holds...

We present a large survey with responses from Swedish firms on their attitudes towards refugees, regarding hiring, job performance, wage setting and discrimination. Generally, firms report positive experiences of having refugees as employees, but we also document a great deal of heterogeneity in...

We present results from a unique nationwide survey conducted in Sweden on sexual orientation and job satisfaction. Our results show that gay men, on average, seem more satisfied with their job than heterosexual men; lesbians appear less satisfied with their job than heterosexual women. However,...
