Open space, residential property values, and spatial context

We use hedonic analysis of home transaction data from the Minneapolis–St. Paul metropolitan area to estimate the effects of proximity to open space on sales price. We allow the effects of proximity to vary with demographic and location-specific characteristics and include fixed effects to control for observed and unobserved neighborhood characteristics. We find that the value of proximity to open space is higher in neighborhoods that are dense, near the central business district, high-income, high-crime, or home to many children. Using the metropolitan area's average value may substantially overestimate or underestimate the value of open space in particular neighborhoods.     

An analysis of some short-term health effects of air pollution in the Washington,D.C. metropolitan area

This study assesses some of the short-term health effects of air pollution in Washington, D.C. Specifically, regression models are formulated to explain health-care visits to a group practice medical care plan. Primary interest is focused on the effects of mobile-source air pollutants, particularly photo-chemical oxidants. Meteorological conditions, as well as other variables thought to influence the consumption of medical services, are included in the models as explanatory variables. The study found only a small effect of air pollution levels on the health-care visits to the group practice.     

The long-run effects of a residential property tax and local public services

The long-run effects of a residential property tax and local public services are analyzed in the context of an urban spatial model. An endogenous labor market allows the local wage rate to adjust, in conjunction with residential and business land prices, in response to local fiscal changes.     

The impact of a state mandated expenditure floor on aggregate property values

Using a test of allocative efficiency in the local public sector developed by Brueckner [Journal of Public Economics 19 (1982) 311–331], this study empirically examines the impact of a state minimum education expenditure requirement on aggregate property values in Connecticut communities. The empirical results reveal that the typical community in Connecticut spends less on education and municipal services than the level that maximizes aggregate property values. The results further indicate that spending on education falls further below the property maximization level in those communities constrained by the state expenditure floor. It follows from the analysis that some state expenditure floors can raise aggregate property values and promote efficiency.     

The economics of property taxes and land values: The elasticity of supply of structures

Land values are explained by diminishing returns to a variable factor, structure, added to fixed land. The total cost minimizing structural density determined by land value, occurs where the marginal cost of increased density equals the average cost of structure plus land. Structural demand prices equal marginal costs in equilibrium determining land demands. A general equilibrium land price establishes the uses, prices and densities of structures. A simple method of calculating structure supply elasticity and the incidence and deadweight loss of property taxes is developed. Differing property tax rates are found to be efficient.     

The effect of voluntary brownfields programs on nearby property values: Evidence from Illinois

Brownfields are properties whose redevelopment is hampered by known or suspected contamination and by concerns about associated liability. Because failing to redevelop brownfields may negatively affect welfare and the environment, a number of states have created voluntary programs to reduce liability risks and encourage redevelopment of brownfields. For clean or remediated properties, the state certifies that owners of such sites are not subject to federal or state liability under certain conditions. Certification could increase nearby property values because of decreased contamination risk and amenities associated with redeveloping the brownfield. This paper focuses on the Site Remediation Program in Illinois, and estimates the effect of brownfields certification on nearby property values. Employing several strategies to account for unobserved and time-varying variables that may be correlated with certification, I find that the entry and certification of a brownfield 0.25 miles away raises the value of a property by about 1% compared to an otherwise identical property.     

Allowing for inefficiency in parametric estimation of production functions for urban transit firms

Efficient versus inefficient observations are first identified and evaluated numerically by the nonparametric free disposal hull (FDH) method. Next, parametric production frontiers are obtained by means of estimating translog production functions through OLS applied to the subset of efficient observations only. Technical progress is included at both stages. Monthly data from three urban transit firms in Belgium, to which this two-stage technique is applied, show widely varying degrees of efficiency over time and across firms, and much less technical progress than standard (i.e., non frontier) econometric estimates suggest.     

The impacts of education spending and finance reform on manufacturing property shadow values: a cost function approach

The effects of court-ordered education finance reform on property values and residential choice have received increasing attention in recent years (Fischel 2001). However, little attention has been focused on the effects of education finance reform on manufacturing sector property values within an optimizing framework. This is pursued here by modeling education expenditures and education finance reform as “free” variables to manufacturing firms in a cost function model together with input demand equations. This framework is applied to panel data on manufacturers’ capital (building and structures) stocks for the 48 continental US for 1982–1996 to estimate implicit (shadow) values to the manufacturing sector of education spending and school finance reform. On average, school finance reform lowers the implicit value of manufacturing firms’ stock of buildings and structures capital, while greater education spending lowers manufacturing variable costs.
