public preferences for hydrogen buses comparing interval data ols and quantile regression approaches we use a quantile regression qr approach to analyse contingent valuation estimates of public willingness to pay wtp for the air and noise pollution reductions associated with the introduction of hydrogen buses in london qr results show that variables that were not significant in interval regression or ordinary least squares regression become significant at certain quantiles along the wtp distribution in addition the determinants of wtp at the lower tail of the distribution differ from those at the higher end of the distribution our findings illustrate the usefulness of quantile regression methods for analysing contingent valuation data enhancing our understanding of the determinants of willingness to pay

valuing the attributes of renewable energy investments increasing the proportion of power derived from renewable energy sources is becoming an increasingly important part of many countries s strategies to achieve reductions in greenhouse gas emissions however renewable energy investments can often have external costs and benefits which need to be taken into account if socially optimal investments are to be made this paper attempts to estimate the magnitude of these external costs and benefits for the case of renewable technologies in scotland a country which has set particularly ambitious targets for expanding renewable energy the external effects we consider are those on landscape quality wildlife and air quality we also consider the welfare implications of different investment strategies for employment and electricity prices the methodology used to do this is the choice experiment technique renewable technologies considered include hydro on shore and off shore wind power and biomass welfare changes for different combinations of impacts associated with different investment strategies are estimated we also test for differences in preferences towards these impacts between urban and rural communities and between high and low income households

heterogeneity in preferences for woody biomass energy in the us mountain west abstract millions of acres of public forest in the us mountain west are substantially degraded and are in need of restoration mechanized restoration treatments can improve forest health and reduce the likelihood of severe wildfire these treatments produce some timber and substantial amounts of forest residues that can be used to generate renewable energy and displace fossil fuels using the choice modeling method this study investigates social preferences for generation of energy with woody biomass produced by restoration treatments on public forests in the mountain west both multinomial logit and latent class logit lcl models are fit to the data and used to estimate marginal willingness to pay mwtp for increased amounts of woody biomass energy generation and important associated co benefits and costs positive and statistically significant mwtp is found for the number of homes powered with wood the extent of healthy forests avoiding increases in the number of large wildfires and local air quality significant heterogeneity was found in respondent preferences for the attributes the heterogeneity can be explained in part by sociodemographic and attitudinal characteristics of respondents the lcl revealed four classes of respondents with distinct preferences revealing conflicting viewpoints toward forest management for woody biomass energy generation

dilemmas of local governance under the development zone fever in china a case study of the suzhou region this article aims to explore the mechanisms of the development zone fever in the suzhou region located in the fast growing yangtze river delta and investigates from an institutional perspective the practice of relevant intragovernmental governance in the context of rapid industrialisation since the 1990s a specific mode of governance the evaluative economic indicators scheme inherited from the earlier socialist planning system combined with the party state s promotion evaluation system plays an essential role in this transformation of farmland property rights however this model of development is not necessarily helpful for local financial conditions and it results in the disclacement of peasants and the loss of land resources based on the resulting dilemmas of governance it is argued that in addition to the economic paradigm which focuses on consequences of fiscal reforms and devolution scholars should pay more attention to factors such as the party state s promotion evaluation system and

a repeated nested logit model of atlantic salmon fishing participation and site choice for atlantic salmon fishing are modeled in the context of a repeated three level nested logit model consumer s surplus measures are derived for different levels of species availability in the penobscot river the most important salmon river in new england for comparison six other travel cost models are estimated these include restrictive cases of the nested logit model a partial demand model and two single site demand models comparisons across these models indicate the importance of modeling the participation decision including income effects and of adopting a nested logit structure rather than a single level logit structure

estimating distributions of willingness to pay for heterogeneous populations random parameters logit models have emerged as a standard approach in estimating public preferences for a range of goods and services however to simplify calculation of welfare measures the marginal utility of income is often assumed to be constant across the population we show that by shifting distributional assumptions from marginal utilities to the welfare measures themselves a random parameters version of a censored logistic regression model cameron 1988 yields distributions of welfare measures more directly and without imposing any unnecessary assumption on the marginal utility of income we develop the theoretical framework for the model and apply it to contingent choice survey data for siting a noxious facility in rhode island in this application our proposed model and random parameters logit yield similar mean willingness to pay but welfare measures are more readily interpretable in the proposed model

locating chinese urban housing policy in an international context china s economic development has often been contrasted with that of other transition economies in europe but academics have fought shy of making direct comparisons of urban housing reform in the two systems this paper fills this gap by making such direct comparisons adopting the market housing model advocated by the world bank as an analytical framework it finds that extensive housing privatisation in china is supported by a system of urban housing property rights and a growing residential mortgage market although china has a distinctive institutional framework there is also much variety among the european transition countries and a distinctive chinese model was not identified so this micro level analysis did not support the contention that china represents a form of contested modernity nonetheless a crucial point arises from china s hybrid status as a developing as well as a transition country the bulk of the urban migrant population remains excluded from formal housing policy and enabling st

the choice theory approach to market research this paper surveys economic choice theory stressing developments that permit use of data from psychometric and conjoint experiments to produce market demand forecasts alternatives to the widely used multinomial logit model are summarized and a new method for estimating multinomial probits is described an integration of choice models with attitudinal scaling and perceptual mapping within a latent variable system is described estimation of such systems under either random effects or fixed effects descriptions of heterogeneity across individuals is discussed issues in the use of choice models to describe responses from conjoint experiments are presented new regression diagnostic tests for the consistency of multinomial logit representations are discussed

willingness to pay for renewable energy primary and discretionary choice of british households for micro generation technologies this paper documents the policy context of renewable energy production in the european union the research adopts a choice experiment approach to investigate households wtp for these renewable energy technologies in the uk the micro generation technologies comprise solar photovoltaic micro wind solar thermal heat pumps and biomass boilers and pellet stoves the study compares the results from conditional and mixed logit models which estimate the distribution of utility coefficients and then derives wtp values as a ratio of the attribute coefficient to the price coefficient with a model in which the wtp distribution is estimated directly from utility in the money space the results suggest that whilst renewable energy adoption is significantly valued by households this value is not sufficiently large for the vast majority of households to cover the higher capital costs of micro generation energy technologies

public support for reducing us reliance on fossil fuels investigating household willingness to pay for energy research and development abstract in order to reduce future dependence on foreign oil and emissions of co2 how much would us households be willing to pay annually to support increased energy research and development r d activities designed to replace fossil fuels does it matter whether the r d includes nuclear energy options we explore these questions using data from a unique set of national telephone and internet surveys using a national advisory referendum format the contingent valuation method is applied to estimate annual household willingness to pay wtp for us household support of a national energy research and development fund erdf for investments in energy sources not reliant on fossil fuels while accounting for the level of un certainty in voting responses the wtp modeling includes a comparison of both classic maximum likelihood estimation mle and bayesian analysis evidence indicates that mle and bayesian analysis achieve similar statistical inference while the bayesian analysis provides a narrower confidence interval around estimated wtp

land leasing and local government behaviour in china evidence from beijing since 2004 two auction mechanisms listing auctions and tender auctions have played a dominant role in land lease arrangements for real estate development in beijing listing auctions in land markets are similar to general english auctions where bidders offer the highest price to win however in tender auctions winners are determined by the bidding price and the bidder s financial capability and reputation based on granted land parcels from 2006 to 2012 in beijing this paper attempts to examine the price differences between the two auctions and the role of land auction in urban development and price stabilisation we find that land policy in beijing which aims to stabilise land prices and to provide low price residences has been integrated with urban development planning in terms of spatial and density pattern land leasing in beijing is not only a land policy but also a part of the strategy framework of local development

when fiscal recentralisation meets urban reforms prefectural land finance and its association with access to housing in urban china by retrieving household level information from 127 938 household heads and fiscal data from 177 prefectures located in eastern and central china this research quantifies the net association between land finance and urban housing tenure while the results demonstrate that in 2005 china s urban housing market remained stratified and simultaneously favoured individuals possessing economic political and human capital the key finding is that net of other household and prefecture level effects land finance is significantly and negatively associated with local homeownership moreover both the demand and supply sides of the urban housing market contribute to such net association by demonstrating the internal links between urban housing and local finance this research not only provides a more holistic view of housing stratification during institutional changes but also lends empirical support to conceptual frameworks that explain a territory based coalition between local governments and selective enterprises

reform without losers an interpretation of china s dual track approach to transition this paper develops a simple model to analyze the dual track approach to market liberalization as a mechanism for implementing efficient pareto improving economic reform that is reform achieving efficiency without creating losers the approach based on the continued enforcement of the existing plan while simultaneously liberalizing the market can be understood as a method for making implicit lump sum transfers to compensate potential losers of the reform the model highlights the critical roles of enforcement of the plan for achieving pareto improvement and full liberalization of the market track for achieving efficiency we examine how the dual track approach has worked in product and labor market liberalization in china

designing a payments for ecosystem services pes program to reduce deforestation in tanzania an assessment of payment approaches abstract payments for ecosystem services pes programs aim to improve environmental outcomes by providing direct incentives to land managers for the provision of ecosystem services participation in pes programs is voluntary so effective program design requires careful consideration of farmers preferences this study quantifies such preferences using a choice experiment the study site is the east usambara mountains tanzania an internationally recognized biodiversity hotspot we assess preferences for four payment approaches constant and variable annual cash payments to individual farmers a constant annual cash payment to a village fund on behalf of farmers and an upfront manure fertilizer payment we find that the manure fertilizer payment was statistically significant in motivating farmer participation while the group payment was non significant in addition the relationship between the likelihood of participation and the stringency of conditionality is surprisingly non linear in a test of external validity average willingness to accept wta values are found to be similar to the average opportunity cost of maintaining land uses consistent with conservation objectives

revealing additional dimensions of preference heterogeneity in a latent class mixed multinomial logit model latent class models offer an alternative perspective to the popular mixed logit form replacing the continuous distribution with a discrete distribution in which preference heterogeneity is captured by membership of distinct classes of utility description within each class preference homogeneity is usually assumed although interactions with observed contextual effects are permissible a natural extension of the fixed parameter latent class model is a random parameter latent class model which allows for another layer of preference heterogeneity within each class this article sets out the random parameter latent class model and illustrates its applications using a stated choice data set on alternative freight distribution attribute packages pivoted around a recent trip in australia

preference heterogeneity for renewable energy technology abstract this study explores heterogeneity in individual willingness to pay wtp for a public good using several different variants of the multinomial logit mnl model for stated choice data these include a simple mnl model with interaction terms between respondent characteristics and attribute levels a latent class model a random parameter mixed logit model and a hybrid random parameter latent class model the public good valued was an increase in renewable electricity generation the models consistently show that preferences over renewable technologies are heterogeneous among respondents but that the degree of heterogeneity differs for different renewable technologies specifically preferences over solar power appear to be more heterogeneous across respondents than preferences for other renewable technologies comparing across models the random parameter logit model and the hybrid random parameter latent class model fit the choice data best and did the best job capturing preference heterogeneity

the effect of mail in utility rebates on willingness to pay for energy star textregistered certified refrigerators the number and variety of governmental programs designed to promote energy efficiency have increased over time examples include mandatory minimum efficiency standards subsidies for more energy efficient goods and services and consumer labels such as the united states environmental protection agency s energy star textregistered while there has been considerable research on the effects of these programs in isolation there has been less of a focus on joint effects or interactions between programs this study examines how the offer of a mail in rebate influences consumer willingness to pay for an energy star certified refrigerator data used for this study were collected from an online survey containing a hypothetical choice experiment conducted in the united states in 2009 results suggest that the offer of a rebate induces uncertainty about the quality of energy star certified refrigerators and thus could actually reduce willingness to pay for such refrigerators

plan and market in china s agricultural commerce this article examines interactions between markets and state commercial planning in the context of china s agricultural sector it begins with a discussion of recent trends in agricultural planning and commerce in china and then presents a theoretical model that analyzes the way that a mixed commercial system of the sort observed in china functions the theoretical analysis suggests that a mixed system is sustainable and can have desirable efficiency and distributional effects markets however limit the range of sustainable plans and in the presence of markets state planning may no longer directly influence production and consumption behavior

china s land market auctions evidence of corruption this paper studies the urban land market in china in 2003 2007 in china all urban land is owned by the state leasehold use rights for land for re development are sold by city governments and are a key source of city revenue leasehold sales are viewed as a major venue for corruption prompting a number of reforms over the years reforms now require all leasehold rights be sold at public auction there are two main types of auction regular english auction and an unusual type which we call a two stage auction the latter type of auction seems more subject to corruption and to side deals between potential bidders and the auctioneer absent corruption theory suggests that two stage auctions would most likely maximize sales revenue for properties which are likely to have relatively few bidders or are cold which would suggest negative selection on property unobservables into such auctions however if such auctions are more corruptible that could involve positive selection as city officials divert hotter properties to a more corruptible auction form the paper finds that overall sales prices are lower for two stage auctions and there is strong evidence of positive selection the price difference is explained primarily by the fact that two stage auctions typically have just one bidder or no competition despite the vibrant land market in chinese cities

industrial capitalisation and spatial transformation in chinese cities strategic repositioning state owned enterprise capitalisation and the reproduction of urban space in beijing this study examines the urbanisation of capital in the context of a socialist economy undergoing profound market transition it identifies the dynamics of state capital as a missing link in understanding the variegated forces shaping chinese cities through a case study of beijing china s capital city contrary to the popular perception of the rolling back of state owned enterprises soes as a natural outcome of capital switching from a declining primary circuit to a booming secondary circuit this empirical study of urban transformation in the beijing metropolis identifies an intriguing trajectory of capitalisation without privatisation whereby the commodification of the land and housing market has been accompanied by a growing share of capital assets under the ownership control of soes and a spatial concentration of state capital toward the city centre since the turn of the new century the development experience centred on the capitalisation of soes is shown to be reflective of the new strategic

perceptions versus objective measures of environmental quality in combined revealed and stated preference models of environmental valuation abstract this study examines perceptions and objective attribute measures in discrete choice models of recreation site choice behavior these forms of attribute measurement are examined in individual and combined revealed preference stated preference models our results suggest that the model based on perceptions slightly outperforms the models based on objective attribute measures however issues such as the definition of the choice set and the measurement of welfare present significant challenges when using perceptions data

reconsidering heterogeneity and aggregation issues in environmental valuation a multi attribute approach the economic valuation of complex environmental goods composed of multiple attributes is an expanding field of research in ecological and environmental economics however several issues are still subjects of debate this paper focuses on three of them the linearity of the valuation function in the attributes aggregation criteria for obtaining social values and the heterogeneity of individuals utility functions a methodological approach based on multi attribute utility theory which enables us to contrast the impact of these concerns on the valuation of environmental goods is proposed we employ the methodology to value a protected natural area and from the results obtained we can conclude that the non linearity and the heterogeneity of the individual utility function are relevant aspects of environmental valuation that need to be taken into account when valuing environmental goods

combining attitudinal statements with choice experiments to analyze preference heterogeneity for functional dairy products abstract in this article we employ a discrete choice experiment to examine preferences for functional dairy product attributes and willingness to pay estimates for consumers in germany we estimate preference heterogeneity by linking stated preference choice data not only to socioeconomic characteristics but also to attitudinal statements in a latent class framework the empirical results indicate the existence of class specific preference heterogeneity based on the consumers attitude towards functional foods emphasizing the importance of attitudinal data in explaining consumers choice behavior our estimates demonstrate that within a class consumers preferences are in accordance with their responses to attitudinal statements that is functional food skeptics prefer non functional dairy products while functional food advocates have a negative preference for non functional dairy products the findings also show that all consumers place high value on dairy products enriched with known functional ingredients such as omega 3 fatty acids

do protest responses to a contingent valuation question and a choice experiment differ it is suggested that the number of protest responses in stated preference surveys depends inter alia on the valuation method used choice experiments ce are said to generate a lower number of protest responses than contingent valuation cv however no comparison of both methods with respect to protest responses has been conducted to date we used both ce and cv in a survey on forest biodiversity in two german regions protest beliefs were measured for all respondents irrespective of whether they were willing to pay or not the results show no clear pattern of differences between ce and cv regarding protest beliefs and protest responses using an attitude scale based on respondents protest beliefs we see a significant negative effect of this attitude on willingness to pay in both methods however in one of the two study regions the effect is weaker in ce than in cv

us consumers willingness to pay for green electricity abstract we analyze us consumers demand for environmental attributes of deregulated residential electricity services using results from a survey designed to elicit consumers willingness to pay for such attributes and using results from a hedonic analysis of actual price premiums charged for green electricity in several deregulated markets survey results suggest that many population segments are willing to pay for decreased air emissions even if there is no alteration in fuel source furthermore several groups are willing to pay significantly more when emissions reductions stem from increased reliance upon renewable fuels the hedonic analysis suggests that several product features not considered in the survey help explain real price premiums including fuel mix from newly created renewable generation capacity green e certification brand name and state of offer while survey and hedonic results are not easily compared due to limitations of the survey both point to similar values for key environmental attributes though the survey results are likely to overstate actual willingness to pay in sum the results suggest that consumer driven purchases can in part support the future of renewable generation capacity in the united states though reliance upon other policy alternatives may be needed if energy prices spike

random preferences towards bioenergy environmental externalities a case study of woody biomass based electricity in the southern united states article i nfo this paper contrasts alternate methodological approaches of investigating public preferences the random parameter logit rpl where tastes and preferences of respondents are assumed to be heterogeneous and the conditional logit cl approach where tastes and preferences remain fixed for individuals we conducted a choice experiment to assess preferences for woody biomass based electricity in arkansas florida and virginia reduction of co2 emissions and improvement of forest habitat by decreasing risk of wildfires and pest outbreaks were presented to respondents as attributes of using green electricity the results indicate that heterogeneous preferences might be a better fit for assessing preferences for green electricity all levels of both attributes were positive contributors to welfare but they were no statistically significant respondents expressed a positive mean marginal willingness to pay wtp for each attribute level the total wtp for green electricity per kilowatt hour was 0 049 kwh or 40 5 per capita year 1 when converted into future total annual expenditures

property rights regimes in complex fishery management systems a choice experiment application the tonle sap wetland fishery was previously divided into 3 different management zones for conservation open access fishing and private fishing rights to the private fishing zone involved auctions for exclusive rights to temporarily designated plots this paper aims to explore the auction based system by investigating how this fishery management system affects different groups of small scale fishermen and how different characteristics of the fishing lots affect the bidding a choice experiment approach was used to model fishermen s choices in a hypothetical auction market by offering fishermen the choice between purchasing different potential fishing lots and a no purchase option implying fishing only in the communal fishing grounds the preferred latent class model with two segments of fishermen showed that the bidding behavior of the more privileged group out competes the other group irrespective of the lot characteristics this result suggests that it is unlikely that the redesign of the auction system itself would be an effective way of securing access to fishing resources for the two observed groups of fishermen this implies that open access fishing grounds and or other regulations may also be needed in future management as they serve an important role for the poorer segments

market potential for smart growth neighbourhoods in the usa a latent class analysis on heterogeneous preference and choice with data from a 2011 national association of realtors community preference survey we examined individuals preferences and the resulting market potential for smart growth neighbourhoods in the usa using a latent class choice model we discovered four classes of individuals that reveal distinctive behaviours when choosing smart growth neighbourhoods based on the interplay between aspects of community design socioeconomic characteristics and personal attitudes based on these results we estimated the demand for smart growth neighbourhoods given the way they are planned and built by linking the results of the latent class choice to a market diffusion model we were able to evaluate the effectiveness of a proposed smart growth neighbourhood design in inducing less sprawling development

using conjoint analysis to quantify public preferences over the environmental impacts of wind farms an example from spain this paper focuses on the effect on people s utility of the potential environmental impacts of wind farm developments we report on research designed to provide insight into their preferences and we show how two alternative choice modelling techniques can be used to estimate them our results show that significant social costs in the form of environmental impacts can be associated with wind farm developments as relative environmental values are revealed by these methods it would be possible to develop wind farms in such a way that minimises the total social costs of the investment and which maximises its net benefits

how do respondents process stated choice experiments attribute consideration under varying information load the popularity of stated choice sc experiments has produced many design strategies in which researchers use increasingly more complex choice settings to study choice behaviour when the amount of information to assess increases we wonder how an individual handles such information in making a choice defining the amount of information as the number of attributes associated with each choice set we investigate how this information is processed as we vary its complexity four ordered heterogeneous logit models are developed each for an sc design based on a fixed number of attributes in which the dependent variable defines the number of attributes that are ignored we find that the degree to which individuals ignore attributes is influenced by the dimensionality of the sc experiment the deviation of attribute levels from an experienced reference alternative the use of adding up attributes where feasible the number of choice sets evaluated and the personal income of the respondent the empirical evidence supports the view that individuals appear to adopt a range of coping strategies that are consistent with how they process information in real markets and that aligning choice complexity with the amount of information to process is potentially misleading relevancy is what matters copyright 2006 john wiley sons ltd

unionization and shareholder interests drawing on agency theory this study examines union nonunion differences in the allocation of both firm profits and business risk to employees and shareholders using a sample of more than 1 000 large private sector firms the authors find that over the period 1970 81 shareholders in unionized firms assumed less of the firm s business risk than shareholders in nonunion firms this finding is interpreted as evidence that managers of unionized firms attempted to minimize agency costs by capitalizing on the incentive effects of risksharing in addition risk adjusted returns to shareholders were lower in unionized firms than in nonunion firms the authors view the relatively poor performance of union firms as a primary motivating factor behind the restructuring of the american industrial relations system during the period studied

combining discrete and continuous representations of preference heterogeneity a latent class approach unobserved preference heterogeneity has been widely recognized as a critical issue not only for modelling choice behaviour but also for policy analysis this paper examines alternative approaches for incorporating heterogeneity in recreational demand we apply a hybrid model combining discrete and continuous heterogeneity representations of tastes to capture the defining features of both the latent class and the random parameter logit specifications this model allows for the joint estimation of discrete segments and within segment heterogeneity providing a richer interpretation of preference heterogeneity a database of recreational trips to forest sites in mallorca has been used to compare the empirical performance of this hybrid approach with common specifications such as the conditional logit the random parameter logit and the latent class model

rural reforms and agricultural growth in china this paper employs province level panel data to assess the contributions of decollectivization price adjustments and other reforms to china s agricultural growth in the reform period decollectivization is found to improve total factor productivity and to account for about half of the output growth during 1978 84 the adjustment in state procurement prices also contributed positively to output growth its impact came mainly from the responses in input use the effect of other market related reforms on productivity and output growth was very small reasons for slowdown in agricultural growth after 1984 are also analyzed copyright 1992 by american economic association

unionization and profitability evidence from the capital market this paper examines the effect of unionization on the profitability of firms abnormal monthly common stock returns for a sample of 253 nyse listed firms are estimated for the month in which the union petitions for an election and for the month in which the national labor relations board certifies the election outcome the results suggest that unionization on average is associated with a reduction in equity value when unions win an election the average loss associated with the unionization drive is 3 8 percent of equity value when unions lose an election there is an average net reduction of 1 3 percent in the equity value of the firm

activities in models of recreational demand scholars have taken divergent approaches to incorporating on site activities into their empirical specifications of site choice models we provide a framework for assessing this methodological heterogeneity through a model that explicitly allows individuals to choose both on site activities and site attributes this model not only conditions the marginal value of site attributes on the choice of an activity but also explicitly recovers the marginal rates of substitution across activities this eliminates previously unrecognized biases in the welfare analysis of changes in site attributes we test hypotheses generated by our model by comparing rival models of demand for access to beaches in costa rica

willingness to pay for renewable energy investment in korea a choice experiment study abstract renewable energy sources are considered as alternatives for coping with the high price of oil and global warming the korean government has set a target that 11 of the total primary energy supply should be obtained through renewable energy sources until 2030 in order to develop proper policies for renewable energy investment it is necessary to analyze the benefits of renewable energy investment based on households willingness to pay this study attempts to apply a choice experiment ce for assessing renewable energy investment in korea moreover we employ a multinomial probit mnp model to relax the assumption that all respondents have the same preferences for the attributes being valued which is usually required in empirical ce studies an mnp model allows the most flexible pattern of error correlation structure the results reveal that the korean public puts a value on the protection of wildlife reduction of pollution and increased employment opportunities on the other hand respondents do not derive significant values from the improvement of landscapes this study is expected to provide policy makers with useful information for evaluating and planning policies related to renewable energy investment

effects on welfare measures of alternative means of accounting for preference heterogeneity in recreational demand models multiattribute revealed preference data are used to investigate heterogeneity in a sample of kayakers for a panel of whitewater sites in ireland this article focuses on a comparison of preference heterogeneity using a random parameter logit model with correlated tastes and a latent class model in terms of the implications for welfare measures of environmental quality and site access changes recreationalists skill levels are found to affect preferences in both approaches statistics for the estimated distribution of welfare changes for the average respondent are computed for changes in site attributes but contrary to previous work these are found to be of similar magnitude

random coefficient models for stated preference surveys abstract this paper combines the use of random coefficient discrete choice models that allow for correlated errors in the form of unobserved preference heterogeneity with an investigation of the reliability and usefulness of rankings data for the data we examine we find significant unobserved preference heterogeneity in the rankings which violates the underlying assumptions of the rank ordered logit model further directly modeling unobserved preference heterogeneity results in significant improvement in the precision of the parameter estimates and in estimated willingness to pay wtp the reliability and usefulness of rankings data should be re examined with econometric models not subject to the independence of irrelevant alternatives iia

fuzzy logic and preference uncertainty in non market valuation in seeking to value environmental amenities and public goods individuals often have trouble trading off the vague good or amenity against a monetary measure valuation in these circumstances can best be described as fuzzy in terms of the amenity being valued perceptions of property rights and the numbers chosen to reflect values in this paper we apply fuzzy logic to contingent valuation employing a fuzzy clustering approach for incorporating preference uncertainty obtained from a follow up certainty confidence question we develop a fuzzy random utility maximization frum framework where the perceived utility of each individual is fuzzy in the sense that an individual s utility belongs to each cluster to some degree the model is then applied to a swedish survey that elicited residents willingness to pay for enhanced forest conservation and to a canadian survey of agricultural landowners that elicited their willingness to accept compensation for a tree planting program both the wtp and wta measures we obtain using the fuzzy approach are well below those obtained using standard probability methods based on goodness of fit measures and monte carlo experimentation a case can be made for using a fuzzy preference approach for modeling preference uncertainty as opposed to incorporating respondent uncertainty within the random utility maximization framework

a semiparametric smooth coefficient estimator for recreation demand we introduce a semiparametric smooth coefficient estimator for recreation demand data that allows more flexible modeling of preference heterogeneity we show that our sample of visitors each has an individual statistically significant price coefficient estimate leading to clearly nonparametric consumer surplus and willingness to pay wtp distributions we also show mean wtp estimates that are different in economically meaningful ways for every demographic variable we have for our sample of beach visitors this flexibility is valuable for future researchers who can include any variables of interest beyond the standard demographic variables we have included here and the richer results price elasticities consumer surplus and wtp estimates are valuable to planners and policymakers who can easily see how all these estimates vary with characteristics of the population of interest

valuing climate protection through willingness to pay for biomass ethanol abstract this study uses a multi part split sample contingent valuation method cvm and fair share fs survey to better understand the public s valuation of mitigating global climate change through its willingness to pay for biomass or cellulosic ethanol in addition to a basic cvm question a related scenario was developed that asked half of the survey respondents to state their fair share cost to lessen a potential food shortage in the next decade also through the expanded use of cellulosic ethanol three alternative biomass feedstocks were assessed farming residues forestry residues and paper mill wastes and municipal solid wastes overall a slightly larger proportion of respondents were wtp extra for cellulosic ethanol in the basic cvm scenario than in the fs scenario though no significant differences were found in the wtp for the different feedstocks bid curve lognormal regression results for the two models were similar supporting the idea that asking a fs rather than a conventional wtp question may be justifiable in some circumstances such as in cases of a national emergency

recreation demand models with taste differences over people we estimate random parameter logit models of anglers choice of fishing site the models generalize logit by allowing coefficients to vary randomly over anglers rather than being fixed the models do not exhibit the restrictive independence from irrelevant alternatives property of logit and can represent any substitution pattern estimation explicitly accounts for the fact that the variation in coefficients over anglers induces correlation in unobserved utility over trips by the same angler willingness to pay for improved fish stock and the value to anglers of specific sites are calculated from the models and compared with the estimates obtained from a standard logit model

does public investment improve homeowners happiness new evidence based on micro surveys in beijing the beijing government has made massive investments in rail transit construction since the 2000s while existing studies provide marginal values for rail access in the real estate market little is known about homeowners happiness evaluation of such public investment using large scale micro survey data this paper estimates in a difference in difference framework the effects on homeowners happiness about public commuting and other residential realms of a transport improvement that altered the residence station distance for some households whilst leaving others unaffected the estimation accounts for the endogeneity between the residential location choice and transport choice by using non market fang gai housing with pre determined residential location it is found that better rail access not only provides sizeable happiness about public commuting to beijing homeowners but also affects their happiness in other residential realms this finding adds to the evidence that public investment has an important role to play in influencing homeowners living experience

union certification in ontario its effect on the value of the firm event study methodology is used to determine the effect of union certification in ontario on the expected profitability of firms raid and non raid applications and the method of certification are examined contrary to expectations we find no strong negative response to certification applications in most cases in general the more contentious the certification process the greater the negative abnormal returns this is not only true within ontario but also when our results are compared to those of the u s

respondent experience and contingent valuation of environmental goods abstract respondent experience i e a respondent s information set has long been suspected to influence contingent valuation estimates of environmental values we assess the influence of experience by explicitly modeling the relationship between respondent experience and both fitted individual resource values and the conditional variance of these estimated values using three different joint specifications for experience and wtp normal censored normal poisson censored normal and zero inflated poisson censored normal we find discrete jumps in resource values as experience increases from zero and that more experienced respondents have smaller conditional variances simulation of arbitrary levels of experience allows standardization of the amount of information when developing welfare estimates

generating electricity with forest biomass consistency and payment timeframe effects in choice experiments abstract this paper presents a choice experiment analyzing the consumers preferences towards a policy for replacing conventional electricity with electricity generated from forest biomass the results show that consumers specially prefer the effects related to the lower risk of forest fires and to the decrease in pressure on non renewable resources the article also presents a methodological test in relation to the payment timeframe and its effect on marginal willingness to pay and consistency of responses using choice experiments the most frequent and realistic payments are associated with lower presence of inconsistent responses finally we cannot reject the null hypothesis of no effects of payment timeframe on marginal willingness to pay

rural versus urban preferences for renewable energy developments development of renewable energy resources such as wind farms and hydro electric schemes are being promoted as a new method of expanding and diversifying employment in rural areas however such energy projects are associated with a range of environmental impacts which might be detrimental to other economic activities such as those based on nature tourism the authors use a choice experiment to quantify peoples preferences over environmental and employment impacts that may result from the deployment of renewable energy projects in rural areas of scotland focussing in particular on any differences between the preferences of urban and rural dwellers and on heterogeneity within these groups rural and urban households are shown to have different welfare gains which are dependent on the type of renewable energy technology and on the scale of project under consideration
