基于不同视角的住房需求研究述评

本文以住房理论描述为线索,从不同角度总结了1960年以来住房需求分析框架。研究发现：1960年以来,住房需求领域的分析框架非常稳定,即以新古典消费者行为理论为指导,构建效用函数和预算约束,根据效用最大化原则推导需求函数,然后进行参数估计和弹性分析。分析技术（如模型构建、变量操作415）的进展和数据质量的提高是推进研究深入的主要动力及进一步的研究方向。     

An analysis of the demand for housing attributes

This paper uses a two-step approach to estimate a system of structural demand equations for housing attributes. Estimation of a hedonic price regression, in the first step, yields implicit prices for housing attributes for the Toronto Metropolitan area in 1978, which are then used to estimate the expenditure share equations derived from the indirect translog utility function. Empirical results indicate that the composite housing attributes (used in the second stage model) are own-price elastic, while an examination of cross price relationships reveals that these attributes are reasonably substitutable.     

Welfare analysis of tax reforms using household data

This paper discusses a methodology for calculating the distribution of gains and losses from a policy change using data for a large sample of households. Estimates are based on the equivalent income function, which is money metric utility defined over observable variables. This enables calculations to be standardised and a computer program to compute the statistics presented in the paper is available for a general demand system. Equivalent income is related to measures of deadweight loss, and standard errors are computed for each of the welfare measures. An application to U.K. data for 5,895 households is given which simulates a reform that involves eliminating housing subsidies.     

A theorem on the identifiability of the von Neumann-Morgenstern utility function from asset demands

If the demand for risky assets is determined by the maximization of an analytical von Neumann-Morgenstern utility function, and if these demands are known as a function of the assets' prices, then this utility function can be constructed without ambiguity.     

An econometric model of tenure choice and demand for housing as a joint decision

This paper models a household's choice of tenure and demand for housing services as a joint decision imposing the restriction that both discrete and continuous decisions are derived from a single preference ordering. The utility index for households is the translog form of the reciprocal indirect utility function allowing for random preferences. Each household chooses between the two main tenures, the owner-occupied and subsidised rental sectors, but households may be rationed in either or both of these sectors and refused admission, in which case they are assumed to enter the third sector, uncontrolled rental. The model is estimated on UK data for 5895 households.     

A cost–benefit analysis of hearing aids,including the benefits of reducing the symptoms of dementia

We carried out a CBA of hearing aids (HAs) in which we estimated the direct utility benefits, and included the indirect utility benefits working through a reduction in dementia symptoms. The benefits methodology involved using QALYs as the outcome measure and then applying the price of a QALY to convert the outcome measure into monetary terms. The price of a QALY was derived from an age-specific VSL estimate. The effects of HAs on utility were estimated from a fixed effects regression on a large national panel data set provided by NACC where we used a negative proxy for the QoL. We also used a fixed effects regression for the estimate of the indirect benefits involving HAs reducing dementia symptoms. We found that the total benefits, mainly coming from the direct benefits, were extremely large relative to the costs, with benefit–cost ratios over 30.     

Characteristics of West German demand for international tourism in the northern Mediterranean region

The purpose of this paper is to establish the economic determinants of West Germany's demand for international tourism in six northern Mediterranean nations. The methodology makes use of the translog utility function. Homotheticity and additivity restrictions of the utility theory are tested as hypotheses. Expenditure (income), own and cross-price elasticities are claculated for each of the twenty years from 1966 to 1985.

Real Estate Market Policy and Household Demand for Housing

This paper used an estimated mixed multinomial logit model of household housing demand to examine the impact of four housing market‐related policies on a stated preference survey sample. The estimated demand probability function suggested that household choice behaviour does show huge heterogeneity. The estimated results were then employed to examine the effects of the policies. We estimated the potential disequilibrium between demand and supply under the construction‐size‐limitation policy, demonstrated that the efficient movers' subsidy increases along with the household income, and simulated the changes in housing demand when tax policy is changed. We demonstrate the potential usefulness of our modelling framework in assisting policy‐making decisions. Our model also partially explains the failures and controversies of the latest real‐estate intervention policies in China.     

Life cycle and housing decisions: a comparison by age cohorts

The use of decomposition methodologies when the involved variable is continuous is not common in the literature. This article uses this methodology, together with other decomposition methodologies, to explain how age can influence on housing decisions. In particular, we use Spanish data to study whether the age of the householder plays a significant role in influencing household decisions with respect to housing tenure and demand. From the comparison of housing decisions between different groups of households classified by the age of the householders, we conclude that age plays the primary role in explaining the gap between households regarding tenure choice, while it shares its importance with other covariates of the model in the housing demand decision.     

Why do similar firms export differently?

Eaton et al. (2011) underline that firms with similar production costs, entry costs and demand export to different countries. In this theoretical article, I provide a rationale for this feature of the data. I demonstrate that similar firms exporting differently can be explained by a baseline trade-off between attractiveness and competition that is present in any model with monopolistic competition. I then show that this trade-off also generates valuable theoretical features including distance-related mark-ups, third country effect and equivalence with random utility models.     

The consumption benefits of investment in infrastructure: The evaluation of sites-and-services programs in underdeveloped countries

The justifications for housing subsidy programs in developing countries often rely upon substantial indirect benefits accruing to program participants (in the form of improved health, earning capacity or employment, or non-market activity). The empirical analysis in this paper suggests that such programs may often be justified solely on the basis of direct impacts. The paper presents a methodology for deriving rigorously the direct Hicksian benefits of housing subsidy programs such as ‘sites-and-services’ and ‘slum upgrading’ projects in developing countries. The methodology is used to evaluate the net benefits of a sites and services project typical of recent urban shelter programs sponsored by the World Bank. The results suggest that the direct benefits of such programs may be substantial. In the particular case analyzed, the rate of return approaches 40 percent.     

Empirical regularities in South African consumption patterns

This article investigates a number of empirical regularities in the South African consumption patterns. The data support the following empirical regularities: (1) variability in consumption systematically exceeds the variability in prices; (2) law of demand; (3) income flexibility is about ?0.5; (4) Engel's law; and (5) the demand hypotheses, demand homogeneity and Slutsky symmetry are acceptable. In contrast to the findings for a number of other countries, another important empirical regularity that consumer's utility function is additive is rejected for the South African consumers. Based on the implied demand elasticity estimates from the preferred model, it is found that food, housing and medical care are necessities, and clothing, furniture, transport and recreation are luxuries and demand for all the commodities are price inelastic.     

Adaptive behavior and the existence of Weizsäcker's long-run indifference curves

Suppose that past consumptions of the first r commodities (r < n) influence present consumption. Then, the long-run demand function to which demand converges maximizes the equilibrium short-run utility function only under very restrictive conditions. The long-run demand functions can be rationalized by a utility function, different from the equilibrium short-run utility function, if and only if the short-run utility function is such that past consumptions of any good that experience, learning, or taste changes is separable from all other goods. The class of such utility functions has been found.     

Micro-simulation and Normative Policy Evaluation: An Application to Some EU Tax Benefits Systems

In this work we explore the impact of alternative tax benefits systems on household welfare. The framework of our analysis is the theory of optimal taxation with the distribution of potential wages replaced by the distribution of household abilities. The latter has been calculated by inversion of the household's utility maximization problem. This methodology has then been implemented in order to compare the tax benefits systems of France and the United Kingdom. We have employed a behavioral micro‐simulation model that has been applied on samples extracted from the “Households Budget Survey 1989” of INSEE and from the “Family Expenditure Survey” of ONS.     

Integrating public demands into model-based design for multifunctional agriculture: An application to intensive Dutch dairy landscapes

The contribution of agriculture to the welfare of society is determined by its economic, social and environmental performance. Although theoretical discussions can be found in the literature, few reports exist that integrate the social demand for multifunctional agriculture in the evaluation of the sustainability and the global welfare of society. This paper presents a methodology that combines economic valuation, integrated modelling, stakeholder analysis, and multi-criteria evaluation. It consists of three steps to determine: (1) social demands for multifunctional agriculture; (2) feasible technical alternatives available from the supply part of the market; (3) the net utility of alternatives for society measured as the change in social net benefit, i.e. the sum of changes compared to the current situation expressed in utility of market and non-market net benefits. Market net benefits are represented by their monetary value. Quality Function Deployment combined with Analytic Network Process (QFD/ANP) were used to estimate the non-market net benefits. The methodology is applied to the case study of a dairy-farming based agricultural landscape in the Northern Friesian Woodlands, The Netherlands. Social net benefit depended on land use, i.e. pasture management regimes on each of the agricultural fields and on presence or absence of hedgerows around the fields. Changes in market net utility were expressed in terms of changes for farmers, consumers and government. Changes in non-market net utility were expressed in terms of changes in landscape quality, nature value and environmental health for Dutch society as a whole, as estimated from European public surveys (Eurobarometer). The complete solution space defined by the market and non-market net benefits of landscapes with alternative patterns of land use was estimated to offer insight in the trade-off between market and non-market performance and enable selection of ‘icon’ landscapes to target or avoid. Improvement of the current landscape towards the social optimum would involve changes in pasture management resulting in higher gross margin for farmers, slightly relaxing current environmental restrictions, which could be reached at lower levels of subsidies in agri-environmental programs. In addition to such overall optimum the results demonstrate the trade-off between market and non-market benefits and the characteristics of current, utopian and dystopian landscapes. The approach provides an alternative to current economic valuation methods which focus on assessment of economic value as an input to analysis. Here, economic value emerges as the trade-off between market and non-market functions which is an output of the analysis.     

Preferences and normal goods: A sufficient condition

This note contains a sufficient condition for all goods to be normal, in the case of differentiable individual demand. This condition appears as a relationship between the first and second partial derivatives of the utility function. But it is shown that this condition is independant of the utility function chosen and, then, is a characteristic of the preference order.     

Inflation and extraordinary returns on owner-occupied housing: Some implications for capital allocation and productivity growth

This paper examines the effects of inflation on the allocation of resources between residential and nonresidential uses and the productivity of capital in the U.S. We begin by calculating the realized rates of return on homeowner equity and the contributions of fixed-rate mortgages and differences in relative inflation rates to extraordinary earned real returns. The paper then focuses on the implications of the extraordinary real returns on residential capital for stock prices and on the demand for owner-occupied housing. Proposals for achieving efficient allocation of capital between residential and nonresidential uses are also considered.     

Intertemporal price discrimination and consumer demand

Under a particular class of utility functions, intertemporal price discrimination (IPD) is not feasible. That is, customers cannot be made to pay different prices for a durable good at different points in time. Other factors such as falling costs, and differing discount rates between buyers and sellers have been found to make intertemporal pricing schemes feasible, or even profitable. None of these factors, however, were fundamental demand differences which give rise to static price discriminations. In this paper we argue that IPD is indeed feasible and sometimes profitable, if only we allow for a nondurable good in the utility function. A simple additively separable utility is examined first, which is then extended to a nonseparable utility function which allows richer substitution/complementary relations between the durable and the nondurable goods. This may help us to better understand the similarities between static and intertemporal price discriminations.     

Austrian Demography and Housing Demand: Is There a Connection

This paper analyses the role of demographic factors in the Austrian housing market. Linking demographic issues, in conjunction with the Austrian private housing finance, to the housing demand is the focus of the empirical model developed in this paper. We find statistical support that the demographic factors help to explain for housing demand. However, we emphasize that demographic factor such as the adult population with net migration effect is only one of the key variables which contributes in understanding the Austrian housing demand. Some of our other empirical findings indicate that the Austrian housing demand is inelastic to various economic factors is a concern for some housing policies.
