In his 1964 book, W. Alonso proposed several concepts of land-use equilibrium in terms of discrete population. However, the so-called new urban economics has been concerned exclusively with continuous population models. It is the authors' belief that in order to develop logical foundations for...

This article presents a micromodel of knowledge creation through the interactions among a group of people. The model features myopic agents in a pure externality model of interaction. Surprisingly, for a large set of initial conditions we find that the equilibrium process of knowledge creation...

How is long run economic growth related to the endogenous diversity of knowledge? We formulate and study a microeconomic model of knowledge creation, through the interactions among a group of heterogeneous research and development (R&D) workers, embedded in a growth model to address this...

A model with a finite number of consumers trading in land that can be changed through production is examined. Unlike most other models in urban economics, land is modeled as measurable subsets of a compact set. Formally, there are three major results. Conditions are found under which a solution...

Conventional wisdom tells us that with no market failure and local nonsatiation of preferences, the core is at least as large as the collection of competitive equilibrium allocations. We confirm this for a standard model featuring private ownership of land. Next we consider the public land...

We offer a guide to the recent literature on the problem of fair allocation, and we present various concepts that have been developed in this literature and the various economic environments in the context of which they have been analyzed.
