the housing market impacts of shale gas development using data from pennsylvania and an array of empirical techniques to control for confounding factors we recover hedonic estimates of property value impacts from nearby shale gas development that vary with water source well productivity and visibility results indicate large negative impacts on nearby groundwater dependent homes while piped water dependent homes exhibit smaller positive impacts suggesting benefits from lease payments results have implications for the debate over regulation of shale gas development jel l71 q35 q53 r31 technological improvements in the extraction of oil and natural gas from unconventional sources have transformed communities and landscapes and brought debate and controversy in the policy arena shale gas plays underlying the populated northeastern united states were thought to be uneconomical less than ten years ago but now contribute a major share of us gas supply 1 natural gas has been hailed as a bridge to energy independence and a clean future because of its domestic sourcing and compared with coal and petroleum derivatives its smaller carbon footprint and reduced emissions of other pollutants e g particulates sulfur dioxide car

private values of risk tradeoffs at superfund sites housing market evidence on learning about risk this paper incorporates a bayesian learning model into a hedonic framework to estimate the value that residents place on avoiding cancer risks from hazardous waste sites we show that residents are

partial identification of amenity demand functions this paper presents a new hedonic framework for reduced form estimation of the demand for spatially delineated nonmarket amenities we begin from a conventional model of market equilibrium where an amenity is conveyed to homeowners by virtue of their residential location choices different housing markets may have different hedonic price functions due to variation across markets in the joint distribution of preferences income regulations and technology in this setting taste based sorting within and across markets confounds point identification of reduced form descriptions for amenity demand curves however we demonstrate that basic knowledge of the sorting process is sufficient to construct instruments that identify bounds on demand curves bounds on demand curves can be translated into ranges of welfare measures for non marginal changes in amenities we find these ranges to be potentially informative in a demonstrative application to evaluating the benefits of improved lake water clarity in the northeast

a hedonic analysis of rent and rental revenue in the subsidised and unsubsidised housing sectors in geneva in this paper an analysis is made of what would be the rent difference for the tenants of subsidised units if these units were rented as unsubsidised units furthermore the existence of any pecuniary disadvantage for the owner of a subsidised unit is investigated by considering his rental revenue i e the amount paid by the tenant and the subsidy it is found that there exists a premium between an unsubsidised and a subsidised unit when using the amount paid by the tenant i e the rent as the dependent variable also the subsidy system in geneva has an influence on the pricing of each characteristic of a unit furthermore it is found that when using rental revenue as the dependent variable both sub samples can be used in a single hedonic equation thus owners of subsidised units are not at a disadvantage due to the granting of a subsidy as a result geneva s subsidy system matches the goals of agents on both the demand and supply sides

valuation of landmass degradation using fuzzy hedonic method a case study of national capital region a hedonic model to determine the revealed willingness to pay for landmass of different suitability classes based on landmass functional characteristics obtained through subjective assessments is developed for the national capital region in india the inherent non specificity involved in subjective evaluation is minimized using fuzzy logic based regression technique the proposed fuzzy regression involves regression using central values of triangular fuzzy number and minimization of non specificity using linear programming the revealed willingness to pay for landmass of different suitability classes is used for valuation of disbenefits due to urban expansion on landmass of different agricultural suitability classes in national capital territory of delhi appropriate pricing policies to prevent the future inappropriate landuse practices are developed using the landmass valuation

efficient estimation of structural hedonic systems when a product or job is not homogeneous but instead embodies several different characteristics it is difficult to use price information about the product to learn anything about the structure of the supply and demand for the embodied characteristics s rosen 1974 highlighted this problem and suggested that the estimated slope of the price characteristic relation the marginal price could be used instead of standard prices in otherwise standard estimation of the supply and demand system however recently brown and h rosen 1982 brown 1983 and mendelsohn 1985 have pointed out that this method is applicable only when the marginal price depends on variables not found in the supply and demand equations in this paper we show that since the hedonic system matches consumers with high demand for the characteristic to firms with low costs of producing it exogenous variables from the supply equation are not valid instruments in the demand equation and vice versa therefore even when the brown rosen mendelsohn brm condition holds estimation of the identified system by standard simultaneous equations techniques will produce inconsistent estimates we then show that the system can be identified despite the absence of the standard instruments and develop an efficient estimator for the identified system since cross equation constraints make estimation of hedonic systems particularly vulnerable to specification error we also consider some specification tests in this section we consider a simple model with only one characteristic the extension to several characteristics is straightforward the basic model developed by rosen can be described as follows firms with different technologies produce products which provide consumers with varying levels of some characteristic z each consumer buys one unit of the good the product is such that an amount of z from two units of the good provides less utility than the same amount of z embodied in a single unit e g acceleration in a car safety in a job consumers

divergence in alternative hicksian welfare measures the case of revealed preference for public amenities this paper investigates the divergence between the two hicksian welfare measures of non traded amenity improvement associated with housing first the hicksian surplus measures for amenity changes are analytically developed based on explicit specification of utility structures a hedonic two stage approach is then applied to empirically show that for quantity changes in contrast to hypothetical markets divergence in real market is small the paper also analytically develops expressions for the income and substitution effects and empirically shows that for a given income effect the greater the substitution effect the smaller the divergence between the two measures copyright 2002 john wiley sons ltd

managerial quality team success and individual player performance in major league baseball this paper uses 1969 87 major league baseball data to investigate the impact of managerial quality on team winning and individual player performance managerial quality and player performance are measured as predicted pay based on salary regressions these market based measures permit conclusions about costs and benefits of managerial quality there are two major findings first when player inputs are controlled for higher quality managers lead to higher winning percentages second players tend to play better relative to their prior performance levels the higher the manager s quality these findings suggest that as emphasized by the human resource management literature the quality of management makes an important difference in the performance of organizations

willingness to pay for car safety evidence from sweden this study estimates a marginal willingness to pay wtp function for a road mortality risk reduction observed marginal wtp from the swedish car market is used and found to be positively correlated with the baseline risk of the cars no statistically significant relationships between examined owner attributes e g wealth and background risk and marginal wtp are found when comparing the estimated monetary value of a non marginal risk reduction derived from the integral of the marginal wtp function with an estimate based on marginal wtp we find in line with expectations that the difference between the estimates is negligible for smaller risk reductions and small 4 10 also for relatively large risk reductions

quantifying the relationship between wealth distribution and aggregate growth in the ramsey model abstract this paper provides an explicit characterization of the relationship between growth and wealth distribution among agents when an economy a la ramsey approaches its steady state the result is used to evaluate the distributional consequence of an increase in the income tax rate

the estimation of demand parameters in hedonic price models this paper shows that the econometric problem of estimating hedonic demand parameters is not a standard identification problem caused by demand supply interaction as has been often assumed estimation procedures based on this assumption lead to biased results the hedonic estimation problem is instead caused by the endogeneity of both prices and quantities when households face a nonlinear budget constraint an instrumental variables solution to this problem is suggested using instruments that exogenously shift the budget constraint

economic insights from internet auctions this paper surveys recent studies of internet auctions four main areas of research are summarized first we survey several studies that document and attempt to explain the frequently observed sniping or last second bidding behavior in these auctions second we summarize several methods proposed to quantify the distortions caused by asymmetric information in these markets most notably due to the winner s curse third we explore research about the role of reputation mechanisms installed to help combat these distortions finally we discuss what internet auctions have to teach us about auction design

housing submarkets and the lattice of substitution this paper aims to stimulate interest in the early micro economic conceptualisation of housing submarkets proposed by rapkin and grigsby which defined market areas in terms of dwelling substitutability three key questions need to be addressed if a return to the rapkin grigsby approach is to be achievable and worthwhile first what are the practical benefits the paper highlights a range of potential research applications that would benefit from the substitutability approach secondly in what way are existing approaches likely to be inadequate for demarcating substitutability based submarkets four criteria are proposed for assessing submarket estimation methods which existing approaches fail to satisfy thirdly what are the prospects for developing a substitutability metric that will make the rapkin grigsby definition empirically feasible a new measure is proposed based on the cross price elasticity of price cpep which is illustrated using data for glasgow scotland

transitional dynamics and the distribution of wealth in a neoclassical growth model abstract the evolution of the personal distribution of wealth in a standard neoclassical growth model is studied if the economy is growing toward the steady state and preferences are such that marginal utility from consumption is infinite finite at some all positive non negative consumption level s then the average saving propensity of agents is positively negatively related to their wealth if the economy is decaying toward the steady state these relationships are reversed if wealth and average saving propensity are positively negatively related the distribution of current period wealth lorenz dominates is lorenz dominated by next period s distribution of wealth

the effect of expenditure aggregation on hypothesis tests in consumer demand systems in this paper cluster analysis is used to identify stochastic hicksian aggregates sha such aggregates comprise goods for which relative prices are constant up to a random element the need to identify such aggregates arises since inappropriate aggregation could influence subsequent estimation and tests results evidence is found that inappropriate aggregation of expenditures influences the outcome of hypothesis tests furthermore cluster analysis appears to identify goods which can be treated as sha it would thus appear that these methods should be used to identify the appropriate goods to aggregate prior to the estimation or testing of demand models

cooperative income allocation in a multi output multi input setting abstract joint enterprises usually allocate returns among member firms in proportion to the value of resources which members have contributed unfortunately market valuations of such resources often are unavailable or poorly represent the resources contributions to enterprise profitability the present paper shows hedonic methods can be used to provide a general formulation of a resource s contribution to cooperative or joint income even when heterogeneous resources are commingled prior to final product sale the formulation is employed to allocate net returns among enterprise members such that no member subsidizes another

identifying hedonic models economic models for hedonic markets characterize the pricing of bundles of attributes and the demand and supply of these attributes under different assumptions about market structure preferences and technology see jan tinbergen 1956 sherwin rosen 1974 and dennis epple 1987 for contributions to this literature while the theory is well formulated and delivers some elegant analytical results the empirical content of the model is under debate it is widely believed that hedonic models fit in a single market are fundamentally underidentified and that any empirical content obtained from them is a consequence of arbitrary functional form assumptions the problem of identification in hedonic models is a prototype for the identification problem in a variety of economic models in which agents sort on unobservable to the economist characteristics models of monopoly pricing michael mussa and sherwin rosen 1978 robert wilson 1993 and models for taxes and labor supply james heckman 1974 sorting is an essential feature of econometric models of social interactions see william brock and steven durlauf 2001 in this paper we address the sorting problem in hedonic models nesheim 2001 extends this analysis to a model with peer effects in this paper we note that commonly used linearization strategies made to simplify estimation and justify the application of instrumental variables methods produce identification problems the hedonic model is generically nonlinear it is the linearization of a fundamentally nonlinear model that produces the form of the identification problem that dominates discussion in the applied literature linearity is an arbitrary and misleading functional form when applied to empirical hedonic models our research establishes that even though sorting equilibrium in a single market implies no exclusion restrictions the hedonic model is generically nonparametrically identified instrumental variables and transformation model methods identify economically relevant parameters even 1 without exclusion restrictions multimarket data widely viewed as the most powerful source of identification achieves this result only under implausible assumptions about why hedonic functions vary across markets

innovation and price the case of digital cameras this study examines a hedonic regression model of digital camera prices using data collected from an internet price comparison service we find that a small number of product characteristics explains most of the variation in camera prices in addition the model demonstrates substantial downward pressure on camera prices during the time period considered we also examine technological innovation shocks to determine their impact on product prices we find that the corresponding price reaction exhibits gradual adjustment over time providing evidence of some degree of anticipation of the innovation as well as a post innovation price shock this study also demonstrates the power of web based shopping services as a new and novel source of data for econometric analysis

estimating british workers demand for safety this paper estimates workers demand function for job safety using the british general household survey data the estimation employs rosen s two stage procedure the main difference between our study and those done in the past is that we estimate hedonic price equations with data sets from two labour markets our approach overcomes the usual identification problems associated with the application of rosen s method the estimation shows that there is a significant wage compensation for job risk in the uk the willingness to pay for a 1 100 000 decrease of annual job fatal accident rate from our estimated workers demand function is about 6 in 1973 prices the estimation of a demand function for safety also enables the derivation of workers willingness to pay for non marginal change of job risk and this can be used for cost benefit analysis on projects involving such non marginal changes

the rising price of husbands a hedonic analysis of dowry increases in rural india dowries in south asia have steadily risen over the last 40 years and now often amount to over 50 percent of a household s assets this paper attempts to investigate the reasons behind this increase it adapts rosen s implicit market model to the indian marriage market and tests predictions from the model with data from six villages in south central india and from the indian census it is found that a marriage squeeze caused by population growth resulting in larger younger cohorts and hence a surplus of women in the marriage market has played a significant role in the rise in dowries

the contagion effect of foreclosed properties although previous research shows that prices of homes in neighborhoods with foreclosures are lower than those in neighborhoods without foreclosures it remains unclear whether the lower prices are the result of a general decline in neighborhood values or whether foreclosures reduce the prices of nearby non distressed sales through a contagion effect we provide robust evidence of a contagion discount by simultaneously estimating the local price trend and the incremental price impact of nearby foreclosures at its peak the discount is roughly 1 per nearby foreclosed property the discount diminishes rapidly as the distance to the distressed property increases the contagion discount grows from the onset of distress through the foreclosure sale and then stabilizes this pattern is consistent with the contagion effect being the visual externality associated with deferred maintenance and neglect

hedonic regressions mis specification and neural networks there is an emerging literature in the field of hedonic regressions which successfully applies flexible functional forms in contrast numerous authors report hedonic regressions with relatively simple functions often with little or no attempt to consider interaction terms and higher level powers such simple functions perform relatively well in spite of good a priori grounds for quite complex interaction effects indeed the studies are characterised by a general indifference to testing these more flexible models even when degrees of freedom permit using detailed scanner data hedonic functions for the uk tv market are estimated and tested for interaction effects for a case study of the market higher level interaction effects are tested for and compare the results with those from a neural network with its property of universal approximation the use of neural networks is particularly novel in this context and some general findings on their suitability emerge

schools and housing markets an examination of school segregation and performance in connecticut this paper estimates a dynamic model of price level school performance and school racial and ethnic composition in the state of connecticut the paper finds that increasing minority representation in a labor market area reinforces the existing pattern of school segregation changes in segregation appear to be influenced by demographic trends in urban areas and by the labour market factors that determine those trends there is no evidence however to suggest that this process affects housing prices rather the housing market appears to adjust relatively quickly

on the choice of funtional form for hedonic price functions this study examines how errors in measuring marginal attribute pric es vary with the form of the hedonic price function in simulations consumers with known utility functions bid for houses with given attributes various forms of the hedonic function are estimated using equilibrium housing prices errors in estimating marginal attribute prices are calculated by comparing each consumer s equilibrium marginal bid vector with the gradient of the hedonic function when all attributes are observed linear and quadratic box cox forms produce lowest mean percentage errors however when some attributes are unobserved or are replaced by proxies linear and linear box cox functions perform best copyright 1988 by mit press

the quiet revolution that transformed women s employment education and family the modern economic role of women emerged in four phases the first three were evolutionary the last was revolutionary phase i occurred from the late nineteenth century to the 1920s phase ii was from 1930 to 1950 phase iii extended from 1950 to the late 1970s and phase iv the quiet revolution began in the late 1970s and is still ongoing three aspects of women s choices distinguish the evolutionary from the revolutionary phases horizon identity and decision making the evolutionary phases are apparent in time series data on labor force participation the revolutionary phase is discernible using time series evidence on women s more predictable attachment to the workplace greater identity with career and better ability to make joint decisions with their spouses each of these series has a sharp break or inflection point signifying social and economic change these changes moreover coincide by birth cohort or period the relationship between the development of modern labor economics and the reality of women s changing economic role is explored the paper concludes by assessing whether the revolution has stalled or is being reversed women who graduated college in the early 1980s did not opt out but recent cohorts are too young to evaluate this abstract was borrowed from another version of this item

which hedonic models can we trust to recover the marginal willingness to pay for environmental amenities abstract the hedonic property value model is among our foremost tools for evaluating the economic consequences of policies that target the supply of local public goods environmental services and urban amenities we design a theoretically consistent and empirically realistic monte carlo study of whether omitted variables seriously undermine the method s ability to accurately identify economic values our results suggest that large gains in accuracy can be realized by moving from the standard linear specifications for the price function to a more flexible framework that uses a combination of spatial fixed effects quasi experimental identification and temporal controls for housing market adjustment

hedonics and demand analysis the implicit demand for player attributes i introduction hedonic analysis is the standard technique of applied econometrics for modeling differentiated products a hedonic price function relates the observed price of a differentiated good to the bundle of characteristics of which the good is composed the derivatives of the function with respect to the characteristics are the implied hedonic prices which empirical work typically seeks to estimate as has been recognized since at least the work of rosen 1974 underlying the hedonic price function is an implicit market for these characteristics a number of studies have attempted to estimate the associated supply demand system in particular applied contexts based on data on the quantities of the characteristics used in the estimation of the hedonic price function and the resulting estimated hedonic prices examples include nelson 1978 witte sumka and erekson 1979 and thomas 1993 rather than a complete supply demand system other authors focus only on the implicit demand for characteristics for example polinsky and rubinfeld 1977 harrison and rubinfeld 1978 agarwal and ratchford 1980 bender gronberg and hwang 1980 blomquist and worley 1981 quigley 1982 mendelsohn 1984 and palmquist 1984 a curious aspect of these studies which appears to have gone unrecognized is the failure to draw on modern econometric demand analysis in the estimation of the implied demand system for the characteristics instead the analysis of the implicit market proceeds on the basis of ad hoc typically linear or loglinear functional forms which involve no explicit derivation from consumer theory and which impose arbitrary and non testable restrictions on preferences as a consequence there is little means beyond descriptive econometric measures goodness of fit examination of signs and t ratios and so on for judging the adequacy or legitimacy of the results no use is made of contemporary flexible functional form methodology which provides a second order approximation to arbitrary preferences and which permits in addition to the calculation of elasticities the testing of fundamental hypotheses of consumer theory such as demand homogeneity and symmetry of the slutsky matrix and numerical checks on the concavity of the associated implied expenditure function the present work attempts to fill this gap however instead of a differentiated good in a product market to which consumer demand theory would apply we choose to study a good in a factor market so that the relevant demand equations are a system of factor demands for the underlying characteristics the good in question is the service of baseball players to major league baseball teams which is a differentiated good in that different players represent different bundles of alternative attributes such as pitching or hitting skills our focus is solely on the implicit demand system for these attributes no attempt is made to estimate the associated supply system reflecting player behavior there are several reasons for this seemingly peculiar choice of commodity first the factor market for baseball players is of some intrinsic interest as evidenced by the extent to which it has been studied by economists for a taste of this see the entry by quirk 1987 in the new palgrave and the recent survey by fort and quirk 1995 in particular the market has been the focus of work by labor economists examples are blass 1992 khan 1993a 1993b and sommers 1992 much of this literature derives from the seminal work of scully 1974 who estimated equations for baseball player salaries as functions of player skills although not previously recognized in these terms underlying scully s salary equations are implicit markets for player skills the previous work involving baseball salary equations by scully 1974 1989 and others for example blass 1992 hill and spellman 1984 fort 1992 pascal and rapping 1972 raimondo 1983 and sommers 1990 is useful because it provides guidance as to the appropriate specification of the hedonic price equation

the welfare economics of land use planning abstract this paper presents an empirical methodology for the evaluation of the benefits and costs of land use planning the technique is applied in the context of the town and country planning system of the uk and examines the gross and net benefits of land use regulation and their distribution across income groups the results show that the welfare and distributional impacts can be large

new estimates of climate demand evidence from location choice abstract we develop and apply to census data a new method for estimating climate demand the method is useful for ranking quality of life based upon a willingness to pay criterion our two major findings are that the willingness to pay quality of life index is correlated with the hedonic approach s ranking but that the migration approach generates much larger estimates of willingness to pay for a more moderate climate this finding is relevant for evaluating the economic impact of global warming

the short run price performance dynamics of microcomputer technologies abstract models of technology growth are often conceived in terms of long run trends in performance and price because in general short run parameter stability and even the form of the growth function have proved elusive yet short run growth models are arguably more useful for managers and research scientists because the majority of their decisions are concerned with discretionary spending and operations rather than longer run strategic plans and investments our research explores short run growth in microcomputer technologies by specifying growth models and parameter estimates for six commercially important computer technologies over short time periods with weekly data observations were acquired in a homogeneous market limited to a collection time frame of less than two years data was collected at granular weekly intervals with concurrent tests to determine whether parameters were stable over successively longer intervals conversely candidate growth models from longer strategic planning horizons were tested to determine whether they scaled down to operational planning horizons we found that an exponential model of performance to price growth is supported over short time horizons in all but one microcomputer technology nonvolatile ram the exponential model and technology specific parameter estimates that are valid over short horizons were found to accurately scale up to longer planning horizons we expect our results to contribute to more accurate price performance forecasting at the corporate and product level better decision making concerning inventory management capacity utilization lead and lag times in supply chain operations and efficiency of logistics

estimating the demand for the characteristics of housing a hstract estimates of the demand for the characteristics contained in a differentiated product such as housing can be based on hedonic regressions however previous studies have not dealt with several potential problems in such estimation a more appropriate framework for the estimation is provided in this paper also data from a number of cities are used to eliminate the identification problem and the endogeneity of the marginal prices derived from non linear hedonic equations is considered in the estimation the results on own and cross price elasticities expenditure elasticities and the effects of socio economic vafiables accord well with expectations

on the choice of functional form for hedonic price functions the empirical results presented in this paper demonstrate the usefulness of quadriatic models in the estimation of hedonic price functions we propose a quadriatic semi log model a restricted case of the quadriatic box cox model whose standardized marginal attribute prices are linear functions of the attribute vector this specification outperforms the linear box cox specification in terms of explanatory power and captures much of the increase in explanatory power provided by the quadriatic box cox model without the corresponding loss in the ability to interpret the coefficient estimates for policy applications the quadriatic semi log model provides a useful alternative to linear specification

hedonic markets and sorting equilibria bid function envelopes for public services and neighborhood amenities abstract hedonic regressions with house value as the dependent variable are widely used to study public services and neighborhood amenities this paper builds on the theory of household bidding and sorting across communities to derive bid function envelopes which provide a form for these regressions this approach allows for household heterogeneity and multiple amenities yields estimates of the price elasticity of amenity demand directly from the hedonic without a rosen two step procedure and provides tests of hypotheses about sorting an application to cleveland area data from 2000 yields price elasticities for school quality and neighborhood ethnic composition and supports the sorting hypotheses

dowry and intrahousehold bargaining evidence from china this paper analyzes the relationship between a woman s intrahousehold bargaining position and her welfare within marriage using household data from rural china simultaneity problems are overcome by using dowry to proxy for bargaining position omitted variable bias is addressed by using grain shocks in the year preceding marriage as an instrument for dowry instrumented dowry positively impacts numerous measures of a wife s welfare including household purchases the time allocation of household members and the woman s satisfaction with life offering strong evidence in support of collective models of the household

power couples changes in the locational choice of the college educated 1940 1990 college educated couples are increasingly located in large metropolitan areas these areas were home to 32 percent of all college educated couples in 1940 39 percent in 1970 and 50 percent in 1990 we investigate whether this trend can be explained by increasing urbanization of the college educated or the growth of dual career households and the resulting severity of the colocation problem we argue that the latter explanation is the primary one smaller cities may therefore experience reduced inflows of human capital relative to the past and thus become poorer

valuing school quality better transport and lower crime evidence from house prices housing prices within urban areas exhibit highly localized variation that cannot be explained solely by differences in the physical attributes of dwellings we consider the role of local amenities and disamenities in generating price variation within urban areas focusing on three highly policy relevant urban issues transport accessibility school quality and crime our survey of the recent empirical literature highlights what is known and what is not known on these issues and considers the relevance and reliability of this evidence for policy design and evaluation although there are serious empirical challenges we argue that research on housing values based on careful research designs can offer credible estimates of the social value of place specific attributes and amenities

does the baseball labor market contradict the human capital model of investment this paper examines whether experienced players in major league baseball are paid more than their contribution to team revenue the author shows that wages increase with experience independently of productivity gains the results therefore contradict the human capital model of investment the evidence is in fact consistent with implicit contract models because most older players are relatively overpaid copyright 1992 by mit press

choice among wage hours packages an empirical investigation of male labor supply this article specifies and estimates an empirical model of male labor supply based on an implicit market model of wage hours determination we discuss how moving from a standard labor supply model to an implicit market model affects model specification and choice of estimation technique we find that average hourly earnings are not independent of hours worked and that ols estimates of the wage hours relationship are biased we also show that a labor supply model that assumes wages to be independent of hours worked produces a positively biased estimate of the effect of the wage on labor supply

pensions and wage premia i introduction despite the widespread acceptance of the theory of compensating differences empirical efforts to estimate the magnitude of these differences have met with only mixed success 1 with the exception of fatal risks economists have not been able to consistently find a significant relationship between wages and other job characteristics the failure to find consistent evidence on compensating differentials has been attributed to either poor measures of non wage characteristics or inadequate controls for worker productivity 2 studies by gunderson hyatt and pesando 1992 montgomery shaw and benedict 1992 and moore 1987 which have been able to explicitly address these issues have had greater success in finding significant compensating differentials in this paper we focus on an alternative explanation for the variation in estimated compensating differentials that the magnitude of the compensating differential varies systematically across different sectors in the labor market the theory of compensating differentials predicts that the implicit price or cost of providing a job attribute such as pensions will be a function of firm or industry technological differences and that the value attached to that attribute will also vary across workers depending on their tastes if workers and firms are not randomly assigned to sectors this will lead to systematic variations in the size of the estimated compensating differential across sectors or markets the result of this variation is that studies using different subsamples of the labor force will yield very different estimates of the size of the compensating differential the few studies that have addressed sources of heterogeneity in compensating differentials have concentrated on testing for individual differences in tastes for risk 3 in contrast our emphasis is on firm side differences in technologies or market power we estimate the compensating differential between annual pension accruals and wage rates and let this tradeoff vary by firm size and union status with corrections for selectivity bias the implicit cost of pensions and hence the size of the compensating differential may vary by finn size or union status for a number of reasons greater ability to spread fixed administrative costs across a large work force more difficulty monitoring worker effort or the presence of market power thus the cost of fringe benefits to the firm may be lower in large or unionized firms than in small nonunion firms we find empirical evidence supporting this view the estimated wage pension compensating differentials are smaller in unionized and large firms than in small nonunion firms the results from this paper are significant for several reasons 1 they provide evidence that compensating differentials vary across markets this evidence could account for some of the differences in estimates of tradeoffs across studies that have used different nonrandom samples 4 more importantly these sectoral differences serve as a reminder that the labor market is in fact a multitude of markets and that technological differences that vary across markets should be considered when addressing issues ranging from estimating the returns to human capital investment to the impact of the minimum wage 5 2 these results also deepen our knowledge of the relationship between pensions and wages a relationship that has important implications for the shape of workers wage earnings profiles or for the mechanisms for motivating workers and for the returns to human capital and for the distribution of income regarding the latter pensions are a large component of compensation and work by even and macpherson 1990 mccarthy and turner 1983 and moore 1987 suggests that coverage rates and returns are smaller for women and blacks our analysis suggests that an element of the differences could be sectoral choices

an empirical analysis of the demand for housing attributes in a third world city this paper presents estimates of the demand for a set of housing attributes using data drawn from the renter and owner occupier housing submarkets for ibadan nigeria the empirical analysis based on an adaptation of rosen s two step model reveals that the most important determinants of the demand for housing attributes are income price of the attribute in question household size and the occupational status of the head of household the paper further indicates that the demand for housing attributes is inelastic since all estimated coefficients are below unity

recreation economics taking stock a decade ago gum and martin 1975 recommended rearranging priorities in outdoor recreation research they urged deemphasis of recreation benefit estimation technique development and advocated instead concentrating on interpreting these estimates in studies of resource allocation four years later batie and shabman 1979 wrote economists have not established relative values for policies and inputs over which agencies have control e g habitat management and fish stocking and instead have focused research efforts on establishing values for recreational services p 931 they added that collectively economists have paid too little attention to the physical production and transformation linkages between public policies and recreation values p 931 just why the profession has failed to heed these admonitions is unclear we can only speculate why the tradition of recreation economics remains synonymous with benefit estimation or nonmarket valuation in this paper we explore plausible explanations and attempt to evaluate their legitimacy in a policyoriented context

which school attributes matter the influence of school district performance and demographic composition on property values abstract increasing levels of segregation in american schools raises the question do home buyers pay for test scores or demographic composition this paper uses connecticut panel data spanning eleven years from 1994 to 2004 to ascertain the relationship between property values and school district attributes such as student test scores and the racial and ethnic composition of the student body town and census tract fixed effects are included to control for neighborhood unobservables the effect of changes in school district attributes is also examined over a decade long time frame in order to focus on the effect of long run changes which are more likely to be capitalized into prices the study finds strong evidence that increases in percent hispanic have a negative effect on housing prices in connecticut but mixed evidence concerning the impact of test scores on property values student test scores also appear to have increased in importance for explaining housing prices in recent years while the importance of percent hispanic has declined finally the study finds that estimates of property tax capitalization increase substantially when the analysis focuses on long run changes

do prices and attributes explain international differences in food purchases food purchases differ substantially across countries we use detailed household level data from the united states france and the united kingdom to i document these differences ii estimate a demand system for food and nutrients and iii simulate counterfactual choices if households faced prices and nutritional characteristics from other countries we find that differences in prices and characteristics are important and can explain some difference e g united states france difference in caloric intake but generally cannot explain many of the compositional patterns by themselves instead it seems an interaction between the economic environment and differences in preferences is needed to explain cross country differences jel d12 i12 l11 l66 q11 food purchases differ across countries within countries over time and across demographic groups these differences seem to be correlated with rates of excess weight gain and diet related illness economists tend to attribute the difference in food purchases across markets to differences in prices an alternative explanation is that they are due to inherent differences in preferences and eating habits in this article we study the differences in food purchases and nutritional outcomes across countries focusing on the united states united kingdom and france we start by systematically documenting the differences in food purchases for consumption at home between the united states united kingdom and france we show that us households purchase different foods from french and uk households for example us households purchase more calories per person a greater percentage of those calories comes in the form of carbohydrates and a lower share in the form of proteins a higher share of expenditure is on drinks and prepared foods and

simultaneity in the market for housing characteristics abstract the nature of simultaneity in the markets for housing characteristics is examined simultaneity is found to arise in the implicit markets for individual characteristics because of the presence of nonlinearity in the market hedonic price function for housing however this simultaneity is not the kind discussed by s rosen j political econ 82 34 55 1974 between firm supplies and household demands as a result the rosen suggestion of identifying demand with firm supply shifters is inappropriate among the alternative approaches to identification the most desirable involve use of data over two or more markets in which residence for a given household is exogenous to the choice of housing

hedonic prices demands for urban housing amenities and benefit estimates abstract this paper uses a rosen two step hedonic price trait demand approach to estimate demand functions for a vector of urban amenities to ascertain whether this theoretically preferred approach yields benefit estimates which differ from the oft used ridker henning one step hedonic approach we conduct a sensitivity analysis we find that the two step approach does yield different benefit estimates and that the differences are large for some amenities the estimates are sensitive to the functional form of the hedonic equation when the forms are significantly different according to modified box cox results but are not particularly sensitive to specification of the amenity demand equation

gender of children bargaining power and intrahousehold resource allocation in china abstract based on the prevalent son preference in china this paper proposes a new measure of relative bargaining power within the household using data from china health and nutrition survey we show that a woman with a first born son has a 3 9 percentage points greater role in household decision making than a woman with a first born daughter having a first born son improves the mother s nutrition intakes and reduces her likelihood of being underweight while thinking of these impacts as being channeled through intrahousehold bargaining power we cannot fully rule out other possible direct effects of a first born son on the outcomes

the process of commercialisation of urban housing in china the role of the state in housing has been the subject of controversial debate recently in china more and more decision makers consider that the supply of housing should be left to market forces of demand and supply various new policies have been introduced from as early as 1979 designed to commercialise and reform the public sector dominated housing system this paper provides a review of housing reforms and a systematic account of the key features of the commercialisation process it focuses principally on the attempts to privatise public sector housing in urban areas in the context of the major characteristics and problems of the urban housing system the development of reform policies and legislation and current reform practice

on the size of u s government political economy in the neoclassical growth model we study a dynamic version of meltzer and richard s median voter model of the size of government taxes are proportional to total income and they are redistributed as equal lump sum transfers voting takes place periodically over time and each consumer votes for the tax rate that maximizes his equilibrium utility we calibrate the model to u s data key elements in the calibration are the income and wealth distribution and the parameters governing the leisure and consumption choices the total size of transfers predicted by our political economy model is quite close to the size of transfers in the data

competition within a cartel league conduct and team conduct in the market for baseball player services a model of major league baseball is developed which distinguishes between league behavior and individual team behavior the league is viewed as setting rules that restrict the team s willingness to pay and or impose costs on the transfer of players between teams given these rules teams then compete for player services the model is estimated and tested the evidence suggests that the restrictive effect of league rules on player salaries declined between 1986 1988 and 1989 1991 consistent with anecdotal evidence within the rules established by the league however teams appear to behave as competitive price takers through the entire sample period

estimating housing demand with an application to explaining racial segregation in cities we present a three stage nonparametric estimation procedure to recover willingness to pay for housing attributes in the first stage we estimate a nonparametric hedonic home price function in the second stage we recover each consumer s taste parameters for product characteristics using first order conditions for utility maximization finally in the third stage we estimate the distribution of household tastes as a function of household demographics as an application of our methods we compare alternative explanations for why blacks choose to live in center cities while whites suburbanize

estimates of the impact of crime risk on property values from megan s laws abstract we estimate the willingness to pay for reductions in crime risk using the location and move in dates of sex offenders we find significant effects of sex offenders locations that are geographically localized house prices within 0 1 miles of a sex offender fall by 4 percent on average we then use this finding to estimate the costs to victims of sexual offenses and find costs of over 1 million per victim far greater than previous estimates however we cannot reject the alternative hypotheses that individuals overestimate risks posed by offenders or that living near an offender poses significant costs exclusive of crime risk jel k42 r23 r31

intra household resource allocation an inferential approach if household income is pooled and then allocated to maximize welfare then income under the control of mothers and fathers should have the same impact on demand with survey data on family health and nutrition in brazil the equality of parental income effects is rejected unearned income in the hands of a mother has a bigger effect on her family s health than income under the control of a father for child survival probabilities the effect is almost twenty times bigger the common preference or neoclassical model of the household is rejected if unearned income is measured with error and income is pooled then the ratio of maternal to paternal income effects should be the same equality of the ratios cannot be rejected there is also evidence for gender preference mothers prefer to devote resources to improving the nutritional status of their daughters fathers to sons

inverse demand systems and welfare measurement in quantity space most studies of welfare or cost benefit analyses are concerned with the welfare effects of price changes 11 19 27 33 50 there are however many situations in which policy options are directly related to quantity changes the welfare effects of price changes are analyzed with the traditional demand system in which commodity quantities are determined as functions of their prices the welfare effects of quantity changes on the other hand are associated with the inverse demand system in which commodity prices are dependent on their quantities in conventional welfare analysis of price change prices are taken to be exogenous or predetermined while quantities are endogenous in contrast in welfare analysis of quantity changes quantities are exogenous while prices are endogenous price based or dual welfare measures are relevant when there are well functioning competitive markets and quantities are fully adjusted to changes in prices on the other hand quantity based or primal welfare measures are useful in situations where there are constraints on commodity quantities or when transaction costs impede consumers from fully adjusting to changes in prices the choice between priceand quantity based welfare measures is empirical and proper measurement of welfare effects requires the knowledge as to which variable price or quantity is the exogenous one for individual consumers it may be reasonable to assume that the supply of commodities is perfectly elastic and therefore prices can be taken as exogenous but this assumption may not be tenable for consumers in the aggregate or if highly aggregated economy wide data are used to estimate demand relations at the aggregate level quantities are more properly viewed as exogenous than are prices although individual consumers make their consumption decisions based on given prices the quantities of commodities are predetermined by production at the market level and prices must adjust so that the available quantities are consumed 28 1 2

nonlinear budget constraints and consumer demand an application to public programs for residential housing abstract this study presents a methodology for exploiting the nonlinear hedonic nature of housing prices to estimate the compensated demands of households for particular housing attributes the methodology is employed to provide hicksian benefit measures of a particular housing subsidy program typical of those undertaken recently in developing countries

dowry and wife s welfare a theotrical and empirical analysis becker attributes the existence of marital transfers to inflexibility in the division of joint product within the marriage if that were the only reason we would not have observed the coexistence of dowries and bride prices this paper offers an alternative analysis while becker s interpretation is retained for bride prices a dowry is now represented as a premortem bequest by altruistic parents for a daughter it not only increases the wealth of the new conjugal household but also enhances the bargaining power of the bride in the allocation of the output within the household thereby safeguarding here welfare using micro data from taiwan we found that a dowry improves the bride s welfare whereas a bride price has no effect these empirical results support the theoretical predictions of the model

testing the neoclassical model of family labor supply and fertility the mcelroy horney nash bargaining model of family demand behavior relaxes the restriction that nonearned income of husband and wife has the identical effect on family labor supply and commodity demands this restriction of the neoclassical model offamily behavior is tested for the determination of husband and wife labor supply andfertility based on the 1981 socioeconomic survey of thailand the neoclassical restriction is rejected for female labor supply andfertility another unexplored limitation offamily demand studies due to the sample self selection of intact marriages is empirically treated through alternative estimation strategies in this case a more sharply focused theory of marital behavior is needed to identify family demand models

efficient estimation of hedonic inverse input demand systems this article is concerned with efficient estimation of characteristics demand we derive and estimate an inverse input demand system for quality characteristics by using 172 946 observations over 881 trading days in the icelandic fish auctions an improved estimation method based on an expanded random coefficient model is suggested as an alternative to the currently used two stage method of brown and rosen the estimates demonstrate the improved efficiency of the suggested method a number of empirical results emerge including a general increase in the demand for quality the purpose of hedonic price analysis is to determine how the price of a unit of a commodity varies with its characteristics that is to estimate the hedonic price function some recent examples of the estimation of hedonic price functions are nerlove combris lecocq and visser and mcconnell and strand however theory predicts that shifts in supply or demand affect the implicit price relationships between the overall price of the good and its individual characteristics and so we need to estimate the underlying demand and supply functions for the characteristics rosen developed a two stage method for analyzing hedonic markets in the first stage of this method the hedonic price function is estimated and in the second stage a system of demand and supply functions for characteristics is estimated using the shadow prices of the characteristics from the first stage as variables brown and rosen showed that this procedure could yield estimates of demand and supply functions that are mere transformations of the coefficients in the hedonic function they suggested the currently used two stage method using data from multiple markets this method utilizes the within market variation to iden

regulation and capitalization of environmental amenities evidence from the toxic release inventory in massachusetts environmental regulation in the united states has undergone a slow evolution from command and control strategies towards market based regulations one such innovation is the toxics release inventory tri a regulation that requires polluting e rms to publicly disclose information about their toxic emissions the basic tenet of this regulation is that it corrects for informational asymmetries between polluters and households allowing communities to pressure polluters to decrease their emissions policy makers have judged the tri a tremendous success as national releases declined by 43 between 1988 and 1999 yet many of the fundamental problems which are known to lead to the classic failure of the coase theorem such as high transaction costs and dife culties in organizing cast doubt on the effectiveness of disclosure rules alone to lead to an efe cient outcome in the caseof pollution we use an event study methodology with high quality data on house prices and other local attributes to assess the extent to which the public values changes in toxic releases and thus the success of tri our major e ndings include 1 declines in toxic releases appear unrelated to any political economy variables that might lead to public activism 2 initial information released under tri had no signie cant effect on the distribution of house prices and 3 house prices show no signie cant impact of declines in reportedtoxic releases over time standard errors aresmall enoughthat we can reject the hypothesis that large declines in toxic releases lead to more than a 0 5 increase in house prices these results also hold when we control for differences in the availability of information on tri and the possible effect of expectations our e ndings cast doubt on the ability of the public to process complex information on hazardous emissions and support the coase theorem in that right to know lawssuch as tri may not be the most effective form of environmental regulation

count data models with variance of unknown form an application to a hedonic model of worker absenteeism we examine an econometric model of counts of worker absences due to illness in a sluggishly adjusting hedonic labor market we compare three estimators that parameterize the conditional variance least squares poisson and negative binomial pseudo maximum likelihood to generalized least squares gls using nonparametric estimates of the conditional variance our data support the hedonic absenteeism model semiparametric gls coefficients are similar in sign magnitude and statistical significance to coefficients where the mean and variance of the errors are specified ex ante in our data coefficient estimates are sensitive to a regressor list but not to the econometric technique including correcting for possible heteroskedasticity of unknown form

an empirical investigation into the performance of ellickson s random bidding model with an application to air quality valuation abstract this paper compares ellickson s random bidding model to the standard hedonic model in estimating benefits due to marginal and non marginal changes in housing attributes using data on the chicago housing market the paper shows that the benefit estimates obtained using the two models are very close in addition various categorizations based on household characteristics are tested in the case of the random bidding model the study shows that the effect of categorization on the overall benefit estimates are negligible moreover the results from the random bidding model reveal that increased income leads to greater demand for environmental quality

for love or money or both this paper explores the implications for economic analysis societal well being and public policy of the movement of care services such as child and elder care from home to market a broad empirical overview sets the stage for the argument that this process cannot be properly evaluated using only a priori judgments about the suitability of marketization the context in which markets operate is crucial and while the growth of market provision poses some risks it also offers some potential benefits

testing a theory of exact aggregation this article analyzes the importance of exact aggregation restrictions and the modeling of demographic effects in jorgenson lau and stoker s 1982 model of aggregate consumer behavior these issues are examined at the household level using canadian cross sectional microdata exact aggregation restrictions and some implicit restrictions on household demographic effects are strongly rejected by our data these results do not preclude pooling aggregate time series data with cross sectional microdata to estimate a model of aggregate consumer behavior they do suggest however an alternative basis for the aggregate model

does energy efficiency matter to home buyers an investigation of epc ratings and transaction prices in england abstract this paper investigates whether energy performance ratings as measured by mandatory energy performance certificates epcs are reflected in the sale prices of residential properties this is the first large scale empirical study of this topic in england involving 333 095 dwellings sold at least twice in the period from 1995 to 2012 applying hedonic regression and an augmented repeat sales regression we find a positive relationship between the energy efficiency rating of a dwelling and the transaction price per square metre the price effects of superior energy performance tend to be higher for terraced dwellings and flats compared to detached and semi detached dwellings the evidence is less clear cut for rates of house price growth but remains supportive of a positive association overall the results of this study suggest that energy efficiency labels have a measurable and significant impact on house prices in england

estimating the structural equations of implicit markets and household production functions whenever marginal prices are nonconstant as in most hedonic and household production function markets ordinary least squares estimates of the price elasticities of structural equations will be biased a two stage least squares estimation procedure is developed and applied to estimate hedonic and potentially household production function demand functions when price gradients are nonlinear

the choice of functional forms for hedonic price equations comment abstract rosen 13 freeman 4 halvorsen and pollakowski 6 and others have stressed that economic theory does not suggest an appropriate functional form for hedonic price functions 1 it consequently is reasonable to try several functional forms and utilize the multiple regression equation with the best performance in this spirit halvorsen and pollakowski 6 recommend using the box cox flexible functional form for hedonic analysis and measuring best performance with a goodness of fit test the box cox methodology has also been adapted in hedonic studies by goodman 5 linneman 10 blomquist and worley 1 and eberts and gronberg 3 2 the box cox is particularly suited for testing functional forms because many familiar forms such as semilog log linear and translog are subsets of the flexible box cox permitting nested hypothesis testing in this note we illustrate that the formal hypothesis testing advantage of the box cox functional form is purchased at the expense of other important goals the goal of most hedonic studies is to estimate the prices of the characteristics to measure the response to changes in the prices and or to predict future expenditures using a best fit criterion to choose functional forms does not necessarily lead to more accurate estimates of characteristic prices in fact the large number of coefficients estimated with the box cox functional form reduces the accuracy of any single coefficient which could lead to poorer estimates of specific prices second because any negative number raised to a noninteger real power is imaginary the traditional box cox functional form is not suited to any data set containing negative numbers third the box cox functional form may be inappropriate for prediction since the mean predicted value of the untransformed dependent variable need not equal the mean of the sample upon which it is estimated the predicted untransformed variable housing value will be biased the predicted untransformed dependent variable may also be imaginary fourth the nonlinear transformation results in complex estimates of slopes and elasticities which are often too cumbersome to use properly we discuss each of these drawbacks and quantify them when possible in the remainder of this note

valuing risk in the workplace market price willingness to pay and the optimal provision of safety the theory of compensating wage differentials attributable to adam smith suggests that jobs with disagreeable characteristics will command high wages ceteris paribus most empirical tests of this theory with hedonic wage equations implicitly assume that workers willingness to pay for risk reduction safety in the workplace through diminished wages and market valuations of the price of these reductions are equivalent it is shown that this is not the case within the manufacturing sector where willingness to pay exceeds the price cost of risk reduction at current levels of risk exposure implications for implied value of life estimates are also examined copyright 1990 by mit press

why women work closer to home this paper analyzes the extent to which differences in labor force status in household composition and in household roles account for sex differences in workplace residence separation modelling work trip length as the outcome of the choice of household residential and individual job locations equilibrium work trip length is estimated empirically as a function of labor market housing and household characteristics for male and female employees in seven different household categories data from the 1976 panel survey of income dynamics are used the study concludes that while sex differences in job tenure work hours and wages are in themselves sufficient to fully account for observed sex differences in workplace residence separation sex differences in household roles i e responses to spouses characteristics are of even greater importance in influencing women to work closer to home

hedonic prices and implicit markets estimating demand and supply functions for differentiated products in choosing the level of quality to purchase the buyer of a differentiated product also chooses a point on the marginal price schedule for that product hence in general the demand functions for product characteristics cannot be consistently estimated by ordinary least squares market equilibrium results in a matching of characteristics of demanders and suppliers this matching restricts the use of buyer and seller characteristics as instruments when estimating demand and supply functions for product characteristics the paper develops these issues a stochastic structure for hedonic equilibrium models is then proposed identification results are presented and estimation procedures are outlined
