This paper investigates the impact of labor markets and economies of agglomeration on firms location. We show that the existence of a lower bound on wage (e.g. a minimum wage or a reservation wage) introduces asymmetric location of firms. Moreover, changes in that lower bound or in global...

In the Dixit-Stiglitz model of monopolistic competition, entry of firms is socially too small. Other authors have shown that excess entry is also a possibility with other preferences for diversity. We show that the cost structure and workers's rents can also explain excess entry

This paper studies how the choice of fixed or flexible exchange rate regimes is affected by the existence of intensive and extensive margins. We study two models where firms enter during or before each period of production. We show how the the choice of those regimes depend on the level and the...

In this paper, we study social interactions between two populations of individuals living in a city. Agents consume land and benefit from intra- and inter-group social interactions. We show that in equilibrium segregation arises: populations get separated in distinct spatial neighborhoods. Two-...
