We study the effects of a decrease in trade costs on the spatial distribution of industry in a multi-regional economy, when a rise in the regional population of workers generates higher urban costs. We show that high and low trade costs imply that all regions involve a positive share of the...

We study the effects of a decrease in trade costs on the spatial distribution of industry in a multi-regional economy, when a rise in the regional population of workers generates higher urban costs. When the number of cities is unaffected by falling trade costs, small cities become smaller for...

We study the effects of decrease in trade costs on the spatial distribution of industry in multi-regional economy, when a rise in the regional population of workers generates higher urban costs. We show that high and low trade costs imply the all regions involve positive share of the industrial...

This paper focuses on externalities between economic agents. We consider spatial dis- tribution of economic activities in a multiregional dynamical system, where regions may be interpreted as clubs, social subgroups, species, or strategies. Our dynamics includes gravity models and replicator...

Asymptotic stability of equilibrium is often difficult to know when the number of variables exceeds four, since all eigenvalues of the Jacobian matrix are not analytically solvable. However, we obtain stability conditions for a general class of migration dynamics without computing eigenvalues....

We consider an economic geography model in which all firms and workers are mobile, but the agglomeration of firms and workers within a region generates urban costs. We show that industries with high transport costs tend to be more agglomerated than industries with low transport costs. This is to...

We consider an economic geography model of a new genre: All firms and workers are mobile and their agglomeration within a city generates costs through competition on a housing market. In the case of two sectors, contrasted patterns arise. When one good is perfectly mobile, the corresponding...

We consider an economic geography model of a new genre: all firms and workers are mobile and their agglomeration within a city generates rising urban costs through competition on a land market. When commuting costs are low (high), the industry tends to be agglomerated (dispersed). With two...

This paper investigates the impact of the heterogeneity of the labor force on the spatial distribution of activities. This goal is achieved by applying the tools of discrete choice theory to an economic geography model. We show that taste heterogeneity acts as a strong dispersion force. We also...
