Urban agglomeration effects and employment and wage gradients

When employment occurs at both central and non-central points, but firms have a preference to be near the center, the rent gradient will decline, and a wage gradient is necessary to compensate workers for more centrally located employment. Wage gradients and rent gradients are jointly determined. The relationship between wage offer functions and the equilibrium wage gradient is derived, the latter dependent on utility functions and commuting costs. This is illustrated with a two sector model incorporating agglomeration economies in the export sector. Numerical solution reveals how agglomeration economies affect wages, employment, and city size.     

The demand for rental housing: Evidence from the Housing Allowance Demand Experiment

This paper provides new evidence on the price and income elasticities of demand for rental housing by low income households. Housing expenditures of households participating in the Housing Allowance Demand Experiment and receiving housing allowances in the form of a proportional rent rebate are analyzed. These rent rebates experimentally vary the effective relative price of housing and thus enable estimation of the price elasticities. Natural income variation enables estimation of income elasticities. Analysis is carried out using two functional forms and a variety of models of housing dynamics. The estimated income and price elasticities of demand are 0.36 and −0.22, respectively. When the sample is restricted to include only households headed by couples, the elasticity estimates are 0.47 for income and −0.36 for price. These estimates are lower (in absolute value) than have been previously estimated and it is suggested that this may be due to the low-income nature of the sample.     

Bureaucracy, monopoly, and the demand for municipal services

A model of municipal budget allocation is constructed. It is assumed that municipalities elect mayors whose preferences reflect those of their constituents and that the bureaucrats heading the public agencies are private-wealth maximizers. Following Niskanen it is argued that bureaucrats exploit their mayors in order to maximize their salaries which implies that the price-elasticity for municipal services will be unitary. A price index is constructed, and the implication is tested on a sample of 81 U.S. cities over the period 1951–1973. The time-series estimates of price, population, and income elasticities are compared with those of Bergstrom and Goodman and Borcherding and Deacon.     

On the possibility of positive rent gradients

The negative rent gradient is a virtually unanimous prediction of urban residential land rent models and a condition of locational equilibrium. This is the result of treating urban rents solely as location rents, where location is defined in terms of accessibility to the CBD. Urban rent may include another component, “externality rent,” which could, for instance, reflect neighborhood externalities in the form of area amenities and pleasant living environments. Introducing externality rent as an element in urban rent makes a positive rent gradient possible, provided that the externality is internalized in the land market. Conditions for a positive rent gradient are determined for both the identical and unequal incomes cases.     

Hedonic price and depreciation indexes for residential housing: A longitudinal approach

An equilibrium price relation is derived for price changes in durable goods capable of generating a hedonic, or quality-corrected, price index, and an index of depreciation. The structure proposed is applicable particularly to housing markets, where longitudinal, or repeat-sale data are readily available from assessment or real estate sources. The separation permits not only the construction of a true price index, but also allows tests of various functional forms for depreciation, notably the geometric function. As an application of the proposed structure, estimates are presented for single-family dwellings in surburban London, Ontario, 1967–1975.     

The possibility of positive rent gradients reconsidered

Despite empirical evidence to the contrary most residential location models are consistent only with a negative rent gradient. Richardson has suggested including average neighborhood plot size as an argument of the utility function; a positive rent gradient is not then a priori inconsistent with equilibrium. However, Richardson does not define the concept of equilibrium, and the purpose of this paper is to suggest a reasonable definition and to show that the rent gradient is negative if the utility function is strictly quasi-concave and if individual and average neighborhood plot size are substitutes.     

Ownership,firm size and rent sharing in Bulgaria

Using a unique three-digit firm-level data set of all medium and large manufacturing enterprises in Bulgaria covering the years 1997–1998, we investigate how wages are affected by ownership status, firm size and rent sharing. Our pooled OLS, panel and first-difference TSLS estimates clearly point to ownership structure as an important determinant of both the wage level (for given productivity) and the degree of rent sharing. Rent sharing is very pronounced in state-owned firms but far less pronounced in private domestic and foreign firms. The results strongly confirm the existence of a multinational wage premium. In addition, we find weak evidence of a positive firm size-wage effect and a positive effect of firm size on the degree of rent sharing. If these effects exist, they are often more pronounced in private domestic firms.     

An empirical investigation of intraurban wage gradients

Intraurban wage gradients have received little attention in the urban literature but have been shown theoretically to be important indicators of the spatial characteristics of urban economic activity. This study examines the spatial distribution of wages of five groups of municipal public employees in the Chicago SMSA. Negative wage gradients, significant at the 0.05 level, are found for four of the five labor groups. Results show that monthly wages decrease on average as much as $24 per additional mile from the city center.     

Hedonic prices, price indices and housing markets

This paper extends hedonic price analysis to the formation of housing price indices measuring variation within a metropolitan area. In forming these indices fifteen submarkets, heterogeneous across time and space, are described within a short-run equilibrium model. Linear functional forms are generally rejected using a method proposed by Box and Cox. Aggregation of hedonic price coefficients into standardized units yields significantly higher housing prices in the central city than in its suburbs, as well as differential effects of structural and neighborhood improvements among submarkets.     

Amenities and Fringe Benefits: Omitted Variable Bias

ABSTRACT If labor is fairly mobile, as it is in the United States, one would expect that households would move from less desirable areas toward more desirable areas until all areas are equally desirable. The way that areas become equally desirable is through the impact of movers on wages and rents (and possibly "endogenous" disamenities, such as congestion or pollution). That is, as people move to desirable areas, they will increase the demand for land (raising rents) and increase the supply of labor (lowering wages); in equilibrium, the wage and rent "compensation" for the niceness of an area reveals, in dollar terms, just how nice the area is. Blomquist, Berger, and Hoehn 1988 demonstrated the empirical importance of such amenity compensation in estimates of the "quality-of-life" in urban areas. However, those authors were unable to include fringe benefits, which are about 40 percent of explicit wage payments, in their wage compensation. This matters greatly as amenities are seen here to be even more important than previously thought and the regional implications are pronounced, with the West and Southeast looking "better" when fringe benefits are included and the East North Central and Northeast looking substantially "worse."     

On the possibility and optimality of positive rent gradients

The assertion that externalities from low density can create positive residential rent gradients is examined in several cases: optimal externality internalization (zoning), excessive and insufficient restriction, and no internalization. In all cases positive rent gradients are unlikely (i.e., require land to be an inferior good), unstable, or impossible. In addition, easily interpretable welfare conditions are found as a result of consumer and social welfare maximization. The Alonso-Muth-Mills model is found to be quite robust.     

Estimating the commuting cost and commuting time property price gradients

In this paper, we estimate the property price gradients in Hong Kong. We distinguish our effort from previous studies on the subject by directly measuring the economic distance, i.e., the monetary commuting cost and commuting time, instead of merely the physical distance. Our results are generally supportive of the prediction of a negative property price gradient. In one specification, the estimated capitalization of the savings of commuting cost in property prices appears to be just right. The expected negative effect of commuting time on property values, however, can only be detected among observations with larger commuting times. Nevertheless, over the range where the effect of commuting time has the expected negative sign, the values of time implied by the estimates agree well with the results reported in the transportation economics literature.     

A New Keynesian model with staggered price and wage setting under learning

This paper provides a study of the implications for economic dynamics when the central bank sets its nominal interest rate target in response to variations in wage inflation. I provide results on the existence, uniqueness, and stability under learning of rational expectations equilibrium for alternative specifications of the manner in which monetary policy responds to economic shocks when nominal rigidities are present. Monopolistically competitive producers set prices via staggered price contracts, and households set nominal wages in the same fashion. In this setting, the conditions for determinacy and learnability of rational expectations equilibrium differ from a model where only prices are sticky. I find that when the central bank responds to wage and price inflation and to the output gap, a Taylor principle for wage and price inflation arises that is related to stability under learning dynamics. In other words, a moderate reaction of the interest rate to wage inflation helps to avoid instability under learning and indeterminacy.     

Wage and price adjustment in a multimarket disequilibrium model

The estimation of wage and price adjustment equations rests heavily on the use of tension variables that aim at capturing the disequilibria in the labour and goods markets. Disequilibrium models therefore provide a natural way of endogenizing these tension variables. This paper estimates jointly a two-market disequilibrium model and a wage and price adjustment block where price and wage growth react to excess effective demands. The estimation is carried out using the simulated pseudo-maximum-likelihood methods developed by Laroque and Salaniè (1989); the results look promising as regards the estimation of even more sophisticated models.     

How good are two-point estimates of urban density gradients and central densities?

Some researchers have estimated urban density gradients and central densities using only information on the population and area of the inner city and the outer ring of suburbs. The statistical properties of these two-point estimates have not been previously analyzed. This paper shows the difficulties in providing a definitive analysis of these properties and provides, as an alternative, some Monte Carlo experiments. It appears that the two-point density gradients are mildly biased downward (toward zero), while the bias on the central density depends on the underlying error structure. Two-point estimates are compared with OLS and nonlinear least-squares estimates. Some results for actual cities are also provided.     

NOMINAL AND REAL WAGE RIGIDITIES IN NEW KEYNESIAN MODELS: A CRITICAL SURVEY

Abstract The labour market is receiving increasing attention in the New Keynesian literature. In this paper, I critically survey this literature in order to highlight the role played by wage rigidities in the explanation of fluctuations caused by technology shocks. To this aim, I present a dynamic stochastic general equilibrium model with sticky prices, nominal wage rigidities and hiring costs. The comparison between this model and that of Blanchard and Gali highlights the non‐trivial differences which exist in the way nominal wage and real wage rigidities drive the economy's dynamics. My conclusion is that models incorporating nominal wage rigidities and some degree of price stickiness provide a better account of macroeconomic dynamics than models with real wage rigidities.

The Variation in Wage Rigidity by Occupation and Union Status in the Us

This study estimates wage equations with data disaggregated by occupation and union status, and it derives two measures of wage rigidity for each group of workers: the sensitivity of wages to unemployment and the speed with which wages respond to price inflation. The sensitivity of wages to an aggregate measure of unemployment was found to depend negatively on an occupation's skill level. In addition, union wages were more sensitive to unemployment than non-union wages and responded less rapidly to price inflation.     

Rent control and homelessness

The purposes of this paper are to produce more precise estimates of the effect of rent control on homelessness using microdata on housed and homeless households and to provide evidence concerning the mechanisms through which rent control might affect homelessness. Our results suggest that rent control does increase homelessness by decreasing the rental vacancy rate and increasing the rental price of housing in the uncontrolled sector but that these effects of rent control are offset by other effects that decrease homelessness. We cannot reject the hypothesis that rent control has no net effect on homelessness.     

The effect of the minimum wage for tipped workers on firm strategy,employees and social welfare

Millions of workers derive much of their income from tips and are subject to the “tipped minimum wage” that differs from the regular minimum wage. This article examines the implications of the tipped minimum wage and shows that increasing it may lead restaurants to adopt a compulsory service charge in lieu of tipping to extract the economic rent enjoyed by waiters under tipping. Because servers are better off with tipping, this implies that increasing the tipped minimum wage in an attempt to increase servers' income may achieve the opposite result. Moreover, increasing the tipped minimum wage may reduce social welfare.
