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.     

Estimating the Demand for Housing, Land, and Neighbourhood Characteristics

This paper provides estimates of the structure of demand for individual housing and neighbourhood characteristics and for land in two British cities. We estimate a hedonic price function, and from this obtain the implicit prices of house attributes. These prices are used to estimate a demand system for each city. These perform well, and enable us to calculate price and income elasticities for each of the non-dichotomous characteristics and for land. To counteract criticisms of demand estimates derived within the hedonic framework a method is developed for selecting an appropriate set of instrumental variables. Estimates derived from this method, however, differ only slightly from those obtained using the conventional techniques. Several features of these estimates provide insights into the unusual characteristics of the British housing market, the effects of constraints imposed by land use planning, and the effects of changing income distribution on the structure of demand.     

The rural-urban population balance again

"This paper explores further the economics of the rural-urban population balance, using the method of comparative statics. It confirms the results obtained by Artle and his colleagues, using the method of excess demand analysis, thus demonstrating that the two methods of analysis are equivalent in this context. In analysing the effects of non-neutral technological change upon urbanization, it is essential to distinguish between the total elasticity of demand for manufactured products, and the income and (compensated) price elasticities, respectively. The empirical plausibility is questioned of assuming that total demand for the aggregate of manufactured goods is elastic."     

Cross-sectional estimation of a simultaneous model of tenure choice and housing services demand

In this paper we analyze the demand for housing services, integrating into a single analysis a systematic treatment of several important conceptual and empirical issues. Our three major objectives are to (1) evaluate the empirical importance of the simultaneity between the tenure choice and consumption level decisions; (2) analyze the relationship between household type and housing demand; and (3) present new estimates of the parameters of housing demand which are based on detailed microdata. In the process, we derive and estimate overall income and price demand elasticities which incorporate the impacts of income and price on both the tenure choice and consumption level decisions.     

Tenure choice and housing demand in Japan

This paper reports the results of an empirical analysis of tenure choice and housing demand that makes use of household-level data from Japan. The paper finds that the price and permanent-income elasticities of demand for owneroccupied housing are approximately −0.8 and 1.4, respectively, and that these estimates are highly robust. The price elasticity estimate is comparable to those for other countries, but the income elasticity estimate is much higher, possibly because of the greater accuracy of the income variable. It is also found that the tenure choice and housing demand decisions are apparently not made simultaneously.     

Estimates of the demand for medical care under different functional forms

We estimate price and income elasticities from a linear, log-linear, and the almost ideal demand model (with and without an adjustment for selectivity bias) in an effort to show that special attention should be paid to the underlying assumptions of consumer behaviour when estimating a medical care demand model. The literature on medical care utilization is extended by incorporating two major components of spending as separate demands in a system of medical care spending. We find that estimates of elasticities vary depending on the functional form of the estimating equation, thus questioning the usefulness for policy purposes of single estimates of elasticities.     

Nonparametric estimation of the impact of taxes on female labor supply

This paper proposes a simple extension of nonparametric estimation methods for nonlinear budget‐set models derived in Blomquist and Newey ( 2002 ) to censored dependent variables. The nonparametric method is applied to estimate female labor supply elasticities using data on married women from the 1985 and 1989 waves of the Panel Study of Income Dynamics, exploiting the substantial variation in budget sets caused by the Tax Reform Act of 1986 as a source of identification. The estimated wage elasticities from this new method are 0.56 overall and 0.27 on the intensive margin. The income elasticity estimates are close to ? 0.67 overall and ? 0.13 on the intensive margin. Compared with the linear labor supply model, the estimated elasticities are usually larger for the nonparametric specifications that account for nonlinear budget sets.

Bilateral trade flows and exchange rate sensitivity: Evidence from likelihood-based panel cointegration

This paper estimates price and income elasticities for bilateral trade equations between Sweden and her eight major trading partners for the period 1960–2001. The methodology used here is the likelihood-based panel cointegration recently developed in the literature. Evidence is found that depreciation of the SEK is expected to improve the Swedish export sector towards six of her eight major trading partners. Regarding Swedish imports, only in four of the eight cases, the price elasticity indicates that depreciation of the SEK decreases Swedish imports. Considering the Marshall–Lerner condition, this is fulfilled for two of the eight countries in the sample. The income elasticities are found to be positive for all countries in the sample. The policy implications of our results are discussed.     

INDIVIDUAL VERSUS AGGREGATE INCOME ELASTICITIES FOR HETEROGENEOUS POPULATIONS

This paper deals with different concepts of income elasticities of demand for a heterogeneous population and the relationship between individual and aggregate elasticities. In general, the aggregate elasticity is not equal to the mean of individual elasticities. The difference depends on the heterogeneity of the population and is quantified by a covariance term. Sign and magnitude of this term are determined by an empirical analysis based on the UK Family Expenditure Survey. It is shown that the relevant quantities can be identified from cross‐sectional data and, without imposing restrictive structural assumptions, can be estimated by nonparametric techniques. It turns out that the aggregate elasticity significantly overestimates the mean of individual elasticities for many commodity groups. Copyright © 2011 John Wiley & Sons, Ltd.     

Econometric analysis of residential time-of-use electricity pricing experiments

This paper adapts the two-stage neo-classical model of consumer behavior to the analysis of time-of-use pricing of electricity. Emphasis is placed upon the relationship between partial elasticities, which can be accurately estimated from the first stage, and total elasticities, which can be estimated only by using less reliable information to estimate the second stage. Three functional forms are implemented with data from the Wisconsin Pricing Experiment. Results indicate that (1) the CES and generalized Leontief functional forms are preferred, (2) price elasticities vary substantially with price, and (3) peak and off-peak electricity are partial substitutes but total complements.     

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.     

Index numbers and demand functions

The article proposes a method of approximating the Konüs true cost of living index, given a system of integrable demand functions. It is shown that the approximation is contained within the Staehle bounds so long as the Engle curves satisfy a weak monotonicity condition. The result is likely to be most useful where the demand functions are known-and known (or constrained) to be integrable-but the solution for the form of the direct or indirect utility function is unknown.     

Issues in measuring a monthly house price index in New Zealand

The sale price appraisal ratio (SPAR) method, which takes the ratios of the current house prices and their previous assessed values to construct an index, has been applied in New Zealand since the 1960s. This paper uses housing market transaction data for 12 cities in New Zealand (1994–2004) to develop monthly SPAR house price indices. These indices were subjected to a variety of statistical tests and benchmarked against the comparable monthly quality controlled weighted repeat sales indices. Finally, the paper provides some useful suggestions for future research based on the SPAR index and other alternative house price indices, such as the assessed value (AV) method.     

Estimation of food demand in Turkey: method of an almost ideal demand system

In this study, data of the household income and consumption expenditure surveys conducted by the Turkish Statistical Institute for 1994 and 2003 years were used; income, price, and cross price elasticities under six aggregated product groups were estimated within the framework of the an almost ideal demand system approach for food expenditures; and estimation of household consumers’ food demand in Turkey was analyzed. According to the findings obtained, it was established that a price-bound change would appear in the food demand, and elasticities were calculated. Expenditures by product groups and price elasticities were obtained, and the product groups were aggregated as bread and cereals; meat, fish, and poultry; milk and dairy products, oil and egg; vegetables and fruits; various fast food and alcoholic and non-alcoholic beverages.     

Residential energy demand in the United States: A regional econometric analysis

A static equilibrium and a dynamic partial adjustment model of residential demand for electricity and natural gas are presented and estimated for the United States over a recent period characterized by sharply increasing energy prices. The static model is estimated using Ordinary Least Squares while the instrumental variables method is used for the dynamic partial adjustment model. The estimates of long-run elasticities suggest the residential demand for electricity and natural gas are price and income elastic. Intercept and slope dummies used in the models identify significant regional differences in demand functions.     

Permanent income,hedonic prices,and demand for housing: New evidence

Housing demand is examined by looking quite specifically at the income and price variables based on individual household data. Permanent and transitory incomes are computed through instrumental variables related to human and nonhuman wealth. A price is constructed by spatially varying hedonic techniques. Separation of measured income into permanent and transitory components substantially improves the predictive power of the housing demand estimation and leads to demand elasticities of +1 and ?1 with respect to permanent income and price. The permanent income elasticity is roughly twice the measured income elasticity.     

Urban disamenities and the measure of economic welfare

A labor market model is used to estimate elasticities between various disamenity factors of urban areas and the wage in those areas. The results are used to calculate a correction to the personal income (PI) data for use in the construction of an index to be used as a measure of economic welfare. The labor supply equation of the model includes some population-related variables which Tobin and Nordhaus have hypothesized represent disamenities of urban living. The labor demand equation is derived from a production function which includes a measure of agglomeration economies. A two-stage least-squares regression analysis provides results which indicate that the hypothesized factors are actually amenity factors. The resulting correction to the personal income data is thus an addition: Economic welfare is higher than that indicated by the PI statistics.     

Demand for electricity in Nigeria: Some empirical findings

This paper presents the findings from an econometric model of Nigerian electricity demand. Electricity consumers are partitioned into three classes-namely. Residential, Commercial and Industrial. It shows that over the last two decades there has been tremendous increase in both the supply and demand for electric energy. Although supply has increased, it has not been able to keep pace with demand. Various explanatory variables that determine changes in demand are analysed for each of the three consuming sectors. The findings are as follows.(i) Per capital income, previous level of electricity consumption and urbanization are the most significant explanatory variables for the Residential sector's electricity consumption. The short and long-run income elasticities are found to be below unity, while whose of urbanization are above unity. The average price of electricity, though rightly signed, was found to be insignificant.(ii) As regards the commercial sector, the significant explanatory variables were previous level of electricity consumption, income, average price of electricity and urbanization. Urbanization was, however, found to be the most sensitive variable in respect to changes in the sector's electricity demand.(iii) Previous level of industrial electricity consumption and degree of urbanization were the main explanatory variables for changes in the Industrial sector's demand for electricity. Industrial output and income were not found to be significant variables in explaining changes in the Industrial sector's demand for electricity.     

Rate of return regulation and the Le Chatelier principle

This paper examines whether rate-of return regulation alters the input quantities firms use to produce their selected output level when the corresponding input prices change, in a manner similar to the Le Chatelier principle. More specifically, would the change in a rate regulated firm’s input quantity due to a change in its input price be less price elastic than the unregulated firm’s change in the input quantity due to a change in its input price. We follow Färe and Logan (1986), Nelson and Wohar (1983) in estimating a rate regulated cost function and capital input share system of equations. Using a 1992–2000 panel of 34 US major investor-owned electric utilities, empirical results indicate that the regulated own-input price elasticities of demand for labor and fuel are less price elastic than their corresponding unregulated own-input price elasticities of demand (a Le Chatelier principle type effect). Having a fuel clause (1) reduces the firm’s willingness to substitute from fuel to either non-fuel (capital, labor) input when the price of fuel rises, and (2) enhances the firm’s willingness to substitute from non-fuel inputs to fuel when the price of non-fuel inputs rises.     

House price risk and the hedging benefits of home ownership

Using a repeat-sales methodology, this paper finds that estimates of house price risk based on aggregate house price indices substantially underestimate the true size of house price risk. This is the result of the fact that aggregate house price indices average away the idiosyncratic volatility in house prices. Additional results show that the idiosyncratic risk exceeds the hedging benefits of home ownership. These results imply that for many home owners, owning a house may well add more price risk than it hedges away. These findings are based on a detailed dataset of individual housing transactions in the Netherlands.
