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...

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...

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...

Hospital cost efficiency is dependent on the potential to generate cost economies, which imply lower costs for hospitals that are, for example, larger or more diversified. Although scale and scope economies have been recognized in the literature on hospital costs, agglomeration economies due to...

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...

In the presence of agglomeration economies one might expect a relocation and concentration of industries. Then firm start-up activities may be assumed to reveal those effects. We introduce an empirical testable model inspired by the New Economic Geography and human capital externalities...

A central feature of many models of location choice - whether of firms or households, within or across cities - is the role of local interactions or spillovers, whereby the payoffs from choosing a location depend in part on the number or attributes of other individuals or firms that choose the...

With the growing recognition of the role played by geography in all sorts of economic problems, there is strong interest in measuring the size and scope of local spillovers (i.e., simple anonymous agglomeration or congestion effects, or more complicated interactions between individuals or firms...

We explain the spatial concentration of economic activity, in a model of economic geography, when the cost of environmental policy - which is increasing in the concentration of emissions - and an immobile production factor act as centrifugal forces, while positive knowledge spillovers and...
