It has long been recognized that the forces that lead to the agglomeration of economic activity and to aggregate growth are similar. Unfortunately, few formal frameworks have been advanced to explore this link. We critically discuss the literature and present a simple framework that can...

This paper proposes a simple theory of a system of cities that decomposes the determinants of the city size distribution into three main components: efficiency, amenities, and frictions. Higher efficiency and better amenities lead to larger cities, but also to greater frictions through...

We survey an emerging literature at the intersection of organizational economics and international trade. We argue that a proper modeling of the organizational aspects of production provides valuable insights on the aggregate workings of the world economy. In reviewing the literature, we...

Using data compiled from concentrated residential urban revitalization programs implemented in Richmond, Virginia, between 1999 and 2004, we study residential externalities. We estimate that housing externalities decrease by half approximately every 1,000 feet. On average, land prices in...

We propose a dynamic spatial theory to analyze the geographic impact of climate change. Agricultural and manufacturing firms locate on a hemisphere. Trade across locations is costly; firms innovate; and technology diffuses over space. Energy used in production leads to emissions that contribute...

We argue that incorporating the decision of how to organize the acquisition, use, and communication of knowledge into economic models is essential to understand a wide variety of economic phenomena. We survey the literature that has used knowledge-based hierarchies to study issues like the...

We use a comprehensive dataset of French manufacturing firms to study their internal organization. We first divide the employees of each firm into layers using occupational characteristics. Layers are hierarchical in that the typical worker in a higher layer earns more, and the typical firm...

We study the impact of information and communication technology on growth through its impact on organization and innovation. Agents accumulate knowledge through two activities: innovation (discovering new technologies) and exploitation (learning how to use the current technology). Exploitation...
