We study a 3-region version of the Footloose Entrepreneur model by Forslid and Ottaviano (J Econ Geogr, 2003). We focus on the analysis of stability of three types of long-run equilibria: agglomeration, dispersion and partial dispersion. We find that the 3-region model exhibits more tendency for...

An economy with ex ante markets for future delivery contingent on ex post spot market prices is considered. Since spot prices are publicly observed ex post, this framework bypasses the enforcement problems that may arise as a result of differential information about states of nature....

We extend an analytically solvable core-periphery model by introducing a monopolistically competitive sector of non-tradable goods that is mobile across regions. We find that when the elasticity of substitution among non-tradable goods is very low, there is agglomeration of all the production...

We use the framework implicit in the model of inflation by Shone (1997) to address the analytical properties of a simple dynamic aggregate supply and aggregate demand (AS-AD) model and solve it numerically. The model undergoes a bifurcation as its steady state smoothly interchanges stability...

We establish that an exchange economy, i.e., preferences and endowments, that generates a giiven aggregate excess demand (AED) function is close to the economy generating the AED obtained by an arbitrary perturbation of the original one.
