This paper explores how the interaction between firm heterogeneity, urban costs and transport costs determines spatial configuration across regions within a simple general-equilibrium model. We spot light on how firm heterogeneity affects the centrifugal and centripetal forces and reshapes the...

A Melitz-style model of monopolistic competition with heterogeneous firms is integrated into a simple new economic geography model to show that the standard assumption of identical firms is neither necessary nor innocuous. We show that relocating to the big region is most attractive for the most...

A Melitz-style model of monopolistic competition with heterogeneous firms is integrated into a simple New Economic Geography model to show that the standard assumption of identical firms is neither necessary nor innocuous. We show that re-locating to the big region is most attractive for the...

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...
