Wages, Rents and Heterogeneous Moving Costs (second version)

The model of compensating differentials in regional labor and land markets was formalized by Roback (1982). The model interprets regional differences in constant quality wages and rents as compensating firms and residents for inter-regional differences in amenities. While the model assumes that the costs of relocating to a new city are zero, the results hold in the presence of moving costs for the marginal migrant. This paper extends the Roback model to allow for moving costs which vary among a city's residents and businesses. This modification of the model generates new interpretations of regional differences in rents and wages. The theoretical results suggests that the interpretation of inter-city rent and wage differentials as compensating is misguided, that such differentials are inappropriate as weights in QOL comparisons and stresses the importance of local housing and labor market parameters in the determination of these differentials. The importance of amenities is retained, but housing supply becomes the main other determinant of regional rents. Housing supply was ignored in the literature following on Roback's initial insight. The new perspective also provides a bridge between the neoclassical perspective implicit in Roback's approach and the newer literature on agglomeration economies. Working Paper 08-0

Mayoral views on housing production: do planning goals match reality?

Mayoral Views on Housing Production: Do Planning Goals Match Reality? evaluates mayoral priorities relative to actual need. Based on our analysis, even the most ambitious mayors are not prioritizing sufficient development necessary to meet the demand for housing and to address the affordability crisis. The authors recommend reforming local zoning codes and reducing regulatory barriers to the construction of multifamily housing to help address this shortfall.Citi Community Development and The Rockefeller Foundatio

Arbitrage in Housing Markets

Urban economists understand housing prices with a spatial equilibrium approach that assumes people must be indifferent across locations. Since the spatial no arbitrage condition is inherently imprecise, other economists have turned to different no arbitrage conditions, such as the prediction that individuals must be indifferent between owning and renting. This paper argues the predictions from these non-spatial, financial no arbitrage conditions are also quite imprecise. Owned homes are extremely different from rental units and owners are quite different from renters. The unobserved costs of home owning such as maintenance are also quite large. Furthermore, risk aversion and the high volatility of housing pries compromise short-term attempts to arbitrage by delaying home buying. We conclude that housing cannot be understood with a narrowly financial approach that ignores space any more than it can be understood with a narrowly spatial approach that ignores asset markets.

Spatial economic aspects of the environment and environmental policy: New directions for research

This paper outlines major new research directions for research on spatial or interregional effects of the environment and envrionmental policy. It attempts to define and characterize key research questions that lie at the intersection of environmental and resource economics and regional and urban economics. This intersection is of considerable importance because at least some factors of production are mobile, both domestically and worldwide. In consequence, information concerning the value of environmental attributes is revealed when people and firms relocate. Additionally, environmental policy changes can alter the interregional or international distributions of factor incomes, population, and production of goods and services.

Why Have Housing Prices Gone Up?

Since 1950, housing prices have risen regularly by almost two percent per year. Between 1950 and 1970, this increase reflects rising housing quality and construction costs. Since 1970, this increase reflects the increasing difficulty of obtaining regulatory approval for building new homes. In this paper, we present a simple model of regulatory approval that suggests a number of explanations for this change including changing judicial tastes, decreasing ability to bribe regulators, rising incomes and greater tastes for amenities, and improvements in the ability of homeowners to organize and influence local decisions. Our preliminary evidence suggests that there was a significant increase in the ability of local residents to block new projects and a change of cities from urban growth machines to homeowners' cooperatives.

Urban Growth and Housing Supply

Cities are physical structures, but the modern literature on urban economic development rarely acknowledges that fact. The elasticity of housing supply helps determine the extent to which increases in productivity will create bigger cities or just higher paid workers and more expensive homes. In this paper, we present a simple model that provides a framework for doing empirical work that integrates the heterogeneity of housing supply into urban development. Empirical analysis yields results consistent with the implications of the model that differences in the nature of house supply across space are not only responsible for higher housing prices, but also affect how cities respond to increases in productivity.

Housing: boom or bubble?

In recent years, the U.S. has seen an extraordinary increase in demand for housing and a rapid rise in house prices. Data show that nationally, the average price of an existing home, adjusted for inflation, rose more than 8 percent in 2004 and 2005, a faster pace than in any previous year. Some people have questioned whether this rapid rise was sustainable, and recent declines in the housing market have made this question more urgent. In "Housing: Boom or Bubble?," Tim Schiller asks whether there was a so-called bubble in house prices or whether fundamental economic factors explain the rapid increase.Housing - Prices
