We study regional migration dynamics in a general framework and provide a foundation for the commonly used two-stage quilibrium. We also examine the robustness of bifurcations when parameters change along arbitrary smooth (C1) paths. We show that bifurcations with crossing equilibrium loci are...

We present two notions of “no arbitrage” in urban economic models and show that there is no model satisfying both. The standard hedonic housing model of urban economics and its generalizations are consistent with the first of these, but inconsistent with the second. We present a model...

We study the indeterminacy of equilibrium in the Fujita-Krugman (1995) model of city formation under monopolistic competition and increasing returns. Both the number and the locations of cities are endogenously determined. Assuming smooth transportation costs, we examine equilibria in...

Despite wide recognition of their significant role in explaining sustained growth and economic development, uncompensated knowledge spillovers have not yet been fully modeled with a microeconomic foundation. This paper illustrates the exchange of knowledge as well as its consequences for...

There have been long-term trends of urbanization and sustained growth across developed and developing countries over the past two centuries. Not only have more cities formed, but the leading metropolises have grown larger, with a number of peripheral subcenters developing over time. Conventional...

The aim of this paper is to explore the structure of cities as a function of labor differentiation, gains to trade, a fixed cost for constructing the transportation network, a variable cost of commodity transport, and the commuting costs of consumers. Firms use different types of labor to...

Review of the 'Handbook of Regional and Urban Economics: Volume 4: Cities and Geography' edited by J.V. Henderson and J.-F. Thisse

Theoretical models of urban growth are surveyed in a common framework. Exogenous growth models, where growth in some capital stock as a function of investment is assumed, are examined first. Then endogenous growth models, where use of some factor by a firm increases the productivity of other...

The goal of this essay is to introduce advanced undergraduates to urban general equilibrium theory.

This is a short dictionary entry. Central place theory is a descriptive theory of market area in a spatial context. Its definition, history, and relation to modern microeconomic theory are provided.
