In contrast to what several papers have argued recently, we show that firm heterogeneity fosters agglomeration of economic activity. If firms are more similar with respect to their total factor productivity, each company faces a lower propensity to export. This renders the home market more...

This paper analyzes the interactions between labor and housing (and land) markets in a city. We develop a monocentric city model involving land development and frictional unemployment and characterize the city's spatial configurations in equilibrium. To better understand the properties of...

This study develops an on-the-job search model involving spatial structure. In this model, workers are either employed and commute frequently to a central business district (CBD) or unemployed and commute less frequently to the CBD in search of jobs. When an unemployed worker succeeds in...

This paper develops a method to measure difficulties in market access over a large set of industries and countries (both developing and developed), during the period 1980–2006. We use a micro-founded heterogeneous-consumers model to estimate the impact of national borders on global and...

Variation in regulatory costs over time and across different types of investment projects creates risk for developers who hold land. These so-called implicit costs, which arise as a result of regulatory delay in the land development process, are hypothesized to be potentially large, but...

Urban areas possess complex spatial configurations. These patterns are produced by cumulative changes in land use and land cover as human and natural environments are influenced by market forces, policy, and changes in the natural landscape. To understand the mechanisms underlying these complex...

Surveys of artists' location choices show that they disproportionately reside in large cities. This paper introduces a model that attempts to explain this urban preference. The model includes four factors: access to other artists; access to consumer demand; access to service jobs; and housing...

This paper uses an economic agent-based model of land use in a hypothetical urban fringe community to examine the effects of large-lot zoning on land conversion, land prices, and the spatial configuration and density of new development. The model incorporates the actions of heterogeneous housing...

The present paper focuses on spatial sorting as a mechanism behind the well-established fact that there is a central region productivity premium. Using a model of heterogeneous firms that can move between regions, Baldwin and Okubo (2006) show how more productive firms sort themselves to the...

While most empirical studies in economic geography document a steady and positive correlation between regional density and firm productivity, the impact is not homogeneous across firms. Importantly, recent international trade literature showed that trading firms are different in terms of...
