Firm agglomeration is positively correlated with productivity, and it exhibits significant heterogeneity across industries. Yet, the connection between agglomeration and corporate investment remains underexplored. We develop a model of information sharing which predicts that knowledge-intensive...

Young highly educated workers developed in the 70 s and 80 s a preference for working in larger cities. As a consequence highly educated young workers in 1990 were over-represented in cities, in spite of the lower wage premium they earned for working in crowded metropolitan areas if compared to...

Young highly educated workers developed in the 70's and 80's a preference for working in larger cities. As a consequence highly educated young workers in 1990 were over-represented in cities, in spite of the lower wage premium they earned for working in crowded metropolitan areas if compared to...

This review discusses frontier topics in economic geography as they relate to firms and agglomeration economies. We focus on areas where empirical research is scarce but possible. We first outline a conceptual framework for city formation that allows us to contemplate what empiricists might...

We introduce knowledge spillovers as an externality in the production function of competitive firms operating in a finite spatial domain under adjustment costs. Spillovers are spatial as productive knowledge flows more easily among firms located nearby. When knowledge spillovers are not...

This chapter reviews academic research on the connections between agglomeration and innovation. We first describe the conceptual distinctions between invention and innovation. We then describe how these factors are frequently measured in the data and some resulting empirical regularities....

Are the observed spatial distributions of firms decided mostly by market-mediated, economy-wide locational forces, or rather by non-pecuniary, sector-specific ones? This work finds that the latter kind of forces weight systematically more than the former in deciding firm location. The analysis...

Pollution-intensive industries are generally characterized by imperfect competition, increasing returns to scale and large transportation costs. We investigate two countries, N and S, each with two sectors. Manufacturing generates cross-border pollution which reduces cross-setoral production in...
