This paper introduces a model where new products are introduced by entrepreneurs or innovating firms in a quasi-temporal setting. Market conditions are characterized by monopolistic competition between varieties belonging to the same product group, where varieties can become obsolete over time...

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...

Firm-level heterogeneity is substantial even in narrowly defined industries. This paper focuses on formulating evolution dynamics which can account for the observed heterogeneity and its maintenance. Based on examination of data on Swedish firm’ supply pattern to different markets over time,...

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...

During a sequence of decades we can observe a co-evolution of globalization through network formation of multinational (MNE) firms and concentration in specific places due to agglomerative forces. First, innovation ideas arrive at a faster speed to firms with past experience of innovation...

In this paper we investigate how various innovation strategies, local knowledge sources and global knowledge pipe-lines influence the likelihood that a firm will be a persistent exporter and the productivity growth of such persistently exporting firms. Using a bivariate logit model and a dynamic...

This paper provides an overview of relevant topics in contemporary research concerned with global, national, regional and local knowledge and innovation dynamics. In particular, we highlight how the global scene is changing in the contemporary world economy that we char-acterize as a knowledge...

Firms in local industries maintain their capability to generate innovations by simultaneously exploiting internal and external knowledge resources. The paper introduces the notion variety triplet to distinguish individual export varieties, where a triplet is a unique combination of a firm, a...

In this paper we analyze how firms’ knowledge absorption capacity – given the knowledge environment – affects the development, adoption and introduction of new export products among Swedish manufacturing firms. Our model formulation builds on theoretical arguments which imply that firms...
