Feenstra and Ma (2008) develop a monopolistic competition model where firms choose their optimal product scope by balancing the profits from a new variety against the costs of 'cannibalizing' sales of existing varieties. While more productive firms always have a higher market share, there is no...

Recent empirical studies suggest that there is a rising trend of market power across sectors in advanced economies. We contribute to this line of research by providing industry-specific evidence for German manufacturing industries, based on representative high-quality firm level data from...

While a considerable body of research examines the strategic orientation-innovation relationship, findings in that literature have been mixed. This article calls attention to an under-investigated problem: the composite, multi-dimensional conceptualization and measurement of most strategic...

This paper investigates the determinants of inter-firm cooperation in research and development (R&D). We analyze the impact of structural and firm specific characteristics, market performance, access to resources and managerial techniques on different types of inter firm R&D cooperation. Based...

We incorporate the spatial dimension into a standard expanding variety growth model based on R&D. The spatial interaction is introduced through spatial production spillovers, knowledge diffusion across space, and the capability for spatial heterogeneity. Forward-looking agents who operate in a...

I investigate the aggregate effects of R&D tax credits in the US. Because it subsidizes R&D activity and because credit rates vary between states, this policy has both spatial and dynamic effects on the economy. To address this issue, I construct an endogenous growth model with spatial...

While both manufacturing and R&D location decisions have received considerable theoretical and empirical attention from economists and organization scientists, theories and evidence regarding the co-location of the two are scarce. The goal of this article is to lay the theoretical foundation for...

Many industries are geographically concentrated. Many mechanisms that could account for such agglomeration have been proposed. We note that these theories make different predictions about which pairs of industries should be coagglomerated. We discuss the measurement of coagglomeration and use...

In this paper, we examine the pattern of spatial concentration of manufacturing industries observed in Tunisia and explore the factors driving firms’ choices of location at the provincial level. We consider specialization and competition indicators as the driving forces and also examine the...
