Canonical analysis of the classical general equilibrium model demonstrates the existence of an open and dense subset of standard economies that possess fully-revealing rational expectations equilibria. This paper shows that the analogous result is not true in urban economies under appropriate...

We develop a model where the unemployed workers in the city can find a job either directly or through weak or strong ties. We show that, in denser areas, individuals choose to interact with more people and meet more random encounters (weak ties) than in sparsely populated areas. We also...

This paper explores the formation of cities through labour specialization, gains to trade, a fixed cost for the transportation network, imperfect competition between firms, and the commuting costs of consumers. The model uses a very general setting, allowing a multidimensional location space and...

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 study develops an overlapping generations model that involves the endogenous determination of demographic and city structure to fully analyze the social and natural changes in city populations. We provide conditions under which the model exhibits the spatial features of demography observed...

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...

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...

We develop a model where the unemployed workers in the city can find a job either directly or through weak or strong ties. We show that, in denser areas, individuals choose to interact with more people and meet more random encounters (weak ties) than in sparsely populated areas. We also...

This paper investigates the impacts of progressive trade openness, technological externalities, and heterogeneity of individuals on the formation of entrepreneurship in a two-country occupation choice model. We show that trade opening gives rise to a non-monotonic process of international...
