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...

Several scholars as well as industry professionals have claimed that there is a "software-biased shift" in the nature and direction of innovation in that software development is a core part of innovation activities in firms across a wide array of industries. Empirical firm-level evidence of such...

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 review and assess the role local institutional framework conditions play in fostering local entrepreneurship. The basic premise is that entrepreneurship is a central driver of economic renewal and change, and that institutions affect both the supply and direction of entrepreneurship. While...

We analyze the rate of formation, the characteristics, and the performance of different types of new firms in Sweden over a decade. Comparisons to Denmark, Brazil, and the U.S. suggest that the environment for new firm formation in Sweden is not markedly different than elsewhere. In line with...

We assess the empirical literature on the determinants of spatial variations in new-firm formation rates by undertaking a systematic empirical analysis of the relative roles of different demand- and supply-side factors. Using instrumental variables to address endogeneity, we find that local...

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...
