This paper develops a framework to appreciate the observed heterogeneity of firm size distributions and the entry and exit of products and firms associated with it. It is based on a model where new products are introduced by innovating firms in a quasi-temporal setting of monopolistic...

A literature study is performed to compile the state-of-the-art, as well as future potential, in SOFC modeling. Principles behind various transport processes such as mass, heat, momentum and charge as well as for electrochemical and internal reforming reactions are described. A deeper...

The paper focuses on challenges and potentials for policy in the presence of fundamental change processes that influence the long-term evolution of regions. The perspective in the paper implies that policy can be viewed as ‘management of change’. We present a conceptual model for...

This paper focuses on a much cited but seldom measured micro-foundation for agglomerations: inter-firm labor mobility. Labor mobility has been advanced as a vehicle for knowledge flows and labor market efficiency, and is often maintained to be an important source of agglomeration economies....

This paper studies the innovative performance of 130 Swedish corporations during 1993-94. The number of patents per corporation is explained as a function of the accessibility to internal and external knowledge sources of each corporation. A coherent way of handling accessibility measures,...

Schumpeter claimed the entrepreneur to be instrumental for creative destruction and industrial dynamics. Entrepreneurial entry serves to transform and revitalize industries, thereby enhancing their competiveness. This paper investigates if entry of new firms influences productivity amongst...

This paper reassesses the relationship between density and productivity by using detailed geo-coded data on wages and employment in Sweden. The contribution is empirical and builds on an analysis of spatial units of exactly the same size in terms of geographic surface. The data divide Sweden...

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 estimate the respective importance of spatial sorting and agglomeration economies in explaining the urban wage premium for workers with different sets of skills. Sorting is the main source of the wage premium. Agglomeration economies are in general small, but are larger for workers with...

Entrepreneurial activity is significantly predicted by the presence of other entrepreneurs in the residential neighborhood. One plausible source of such spatial clustering is local peer effects, where individuals’ decisions to become entrepreneurs are influenced by entrepreneurial neighbors....
