We develop a general equilibrium model with three primary production factors—land, skilled, and unskilled labor—and three sectors—construction, intermediate inputs, and final consump-tion—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 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...

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 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...

We harness big data to detect prime locations—large clusters of knowledge-based tradable services—in 125 global cities and track changes in the within-city geography of prime service jobs over a century. Historically smaller cities that did not develop early public transit networks are less...

We develop a new general equilibrium monopolistic competition model with variable demand elasticity, heterogeneous firms, and multiple asymmetric regions. Wages, productivity, consumption diversity, and markups across firms and markets are all endogenously determined and respond to trade...
