This article examines unemployment disparities and efficiency in a densely populated economy with two job centers and workers distributed between them. We introduce commuting costs and search-matching frictions to deal with the spatial mismatch between workers and firms. In equilibrium, there...

This study challenges the prevailing theories of modern macroeconomics based on observations of a real economy and skepticism toward existing theories. Two main hypotheses are tested. First, the price mechanism is significantly incomplete in a Walrasian economy and does not function,...

A simple model of production with heterogenous ability is developed. The median ability of employed workers is linked to the production elasticity of labor, causing an externality for individual firms. Due to this externality, an equilibrium allocation with a moderate level of unemployment is...

We analyze whether different learning abilities of firms with respect to general equilibrium effects lead to different levels of unemployment. We consider a general equilibrium model where firms in one sector compete à la Cournot and a real wage rigidity leads to unemployment. If firms consider...
