Tech clusters play a growing role in knowledge-based economies by accommodating high-tech firms and providing an environment that fosters location-dependent knowledge spillovers and promote R&D investments by .rms. Yet, not much is known about the economic conditions under which such entities...

We consider an economic geography setting in which firms are free to choose one of the following organizational types: (i) integrated firms, which perform all their activities at the same location, (ii) horizontal firms, which operate several plants producing the same good at different...

We develop a general equilibrium model with three primary production factors - land, skilled, and unskilled labor - and three sectors - construction, intermediate inputs, and final consumption - to study how different intensities of telecommuting affect the efficiency of firms that embrace home...

In recent years the land-rent gradient for the city of London has flattened by 17 percentage points. Further, teleworking has increased 24 percentage point for skilled workers, but much less for unskilled workers. To rationalize these stylized facts, we propose a model of the monocentric city...

We develop a general equilibrium model of monopolistic competition with a traded and a non-traded sector. Using a broad class of homothetic preferences - that generate variable markups, display a simple behavior of their elasticity of substitution, and nest the ces as a limiting case - we show...

Our novel approach to modeling monopolistic competition with heterogeneous consumers involves a space of characteristics of a differentiated good (consumers' ideal points), alike Hotelling (1929). Firms have heterogeneous costs à la Melitz (2003). In addition to price setting, each firm also...

Our novel approach to modeling monopolistic competition with heterogeneous firms and consumers involves spatial product differentiation. Space can be interpreted either as a geographical space or as a space of characteristics of a differentiated good. In addition to price setting, each firm also...
