This paper analyzes the role of knowledge accessibility in re¬gional economic growth. The research question is the following: can the variation in knowledge accessibility between regions in a given period explain the variation in their growth performance in subsequent periods? As knowledge...

This paper revisits a classical inquiry by addressing the question of localization and urbanization economies. We propose that specialization and diversity may offer externalities operating at different spatial scales. Using high-resolution geo-coded plant-level panel data for Swedish cities...

We use comparable micro level panel data for 14 countries and a set of identically specified empirical models to investigate the relationship between exports and productivity. Our overall results are in line with the big picture that is by now familiar from the literature: Exporters are more...

There is a need for a conceptual approach that, with reference to explicit micro-level mechanisms and processes of industrial dynamics, articulates the role and function of entrepreneurial experimentation in innovation systems. This paper develops the concept of "entrepreneurial systems of...

Sorting of high-ability workers is a main source of urban-rural disparities in economic outcomes. Less is known about when such human capital sorting occurs and who it involves. Using data on 15 cohorts of university graduates in Sweden, we demonstrate significant sorting to urban regions on...

As cities increasingly become centers of economic growth and innovation, there is a need to understand their inner workings and organization in greater detail. We use ge-coded firm-level panel data at the sub-city level to assess the long-standing question whether agglomeration economies derive...

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 use longitudinal data over a decade on start-ups and employment in Swedish regions and analyze the effect of start-ups on subsequent employment growth. We extend previous analyses by examining the influence of regional start-ups in a sector on regional employment growth in the same sector and...
