An important weakness of innovation system theory is a neglect of the international dimension. A central proposition rests on dynamic agglomeration economies: interactive learning requires co-location, hence a preference for national linkages. The analysis focuses on adjustments of national economic structures and institutions that are necessary to cope with the accelerated pace of change and t...

Productivity determinants of the urban domestic electricity sector in a crosssection of EU countries are examined to unveil the existence of two forms of spillover effects: those from foreign firms (foreign spillovers) and those related to spatial interactions (spatial spillovers). The empirical analysis also assesses the importance of industrial disaggregation in the context of the ongoing pol...

Despite wide recognition of their significant role in explaining sustained growth and economic development, uncompensated knowledge spillovers have not yet been fully modeled with a microeconomic foundation. The main purpose of this paper is to illustrate the exchange of knowledge as well as its consequences on agglomerative activity in a general-equilibrium search-theoretic framework. Agents, ...

Mainstream economic literature has often neglected spatial issues. Marshall having initiated the study of agglomeration economies, these were then only further pursued in specialized lines of research in economics and economic geography. General interest in them was revived by the "new economic geography" when it applied new economic tools and concepts to their study. However, in order to under...

This paper proposes to investigate the effect of spillovers on firms’ R&D investment decisions. We develop an analysis merging the geographer’s toolbox with standard econometric techniques. For a chosen sample of sectors, we test the existence of positive spatial autocorrelation at the level of R&D investments. We provide results on how far the local environment may influence the firms’ investm...

We seek to better understand the scheduling of activities in time through a dynamic model of commuting with congestion, in which workers care solely about leisure and consumption. Implicit preferences for the timing of the commute form endogenously due to concave preferences and temporal agglomeration economies. Equilibrium exists uniquely and is indistinguishable from that of a generalized ver...
