The paper describes within-neighborhood economic segregation in U.S. metropolitan areas in 1985 and 1993. It uses the neighborhood clusters of the American Housing Survey, standardized by metropolitan area income and household size, to explore income distribution within neighborhoods at a scale...

For thousands of years, the Chinese and many other nations around the workd built defensive walls around their cities. This phenomenon is not well understood from an economic perspective. To rationalize the existence of city walls, we propose a simple model that relates the deimesions of city...

This paper studies purely empirically aspects of the distribution of income within small neighborhoods and contrasts it with the income distribution at higher level of aggregation, such as census tracts and metropolitan areas. It relies on a unique feature of the American Housing Survey, whose...

This paper develops a model of housing decisions which allows for social interactions within residential neighborhoods to impact homeowners' valuation of their own properties. The model is used to structure an empirical investigation with data from the American Housing Survey for 1985 and 1989....

The paper adapts to richer social structures the Brock-Durlauf model of interactive discrete choice, where individuals’ decisions are influenced by the decisions of others. Social structure is modelled by a description of who interacts with whom, by means of a graph, with individuals as...

Empirical studies of social interactions address a multitude of de¯nitional, econo- metric and measurement issues associated with role of interpersonal and social group in°uences in economic decisions. Applications range from studies of crime patterns, neighborhood in°uences on upbringing and...

US output growth became much more stable over the past half-century. This paper assesses the role of changes in the composition of output | the increasing importance of stable sectors and diminishing importance of volatile sectors | in this stabilization. Our decomposition of output growth...
