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...

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...

The authors characterize the class of dynamic models that allow for the most commonly used types of sustained economic growth (balanced and asymptotically balanced). They show that, under a constant returns to scale technology, (asymptotically) constant discount rate and (asymptotically)...

An overlapping-generations model where agents choose whether to become educated when young is presented. Education enhances productivity, but needs to be financed by borrowing. Because of the possibility of default, lenders may ration credit. We characterize the steady-state equilibrium with and...

Numerous studies document that criminal activity is positively related to unemployment and negatively related to educational attainment levels within given communities. We study this phenomenon in the context of a search-equilibrium model, in which agents choose between formal employment and...

This article develops a two-country endogenous growth model with accumulation of both physical and human capital. We establish the existence of two-country balanced growth equilibria with physical and human capital in which a static and dynamic version of the Heckscher-Ohlin (HO) hypothesis hold...
