sensitivity to scale in contingent valuation the importance of the budget constraint the possible insensitivity of willingness to pay wtp values to changes in scale continues to cause concern within the contingent valuation cv literature although several reasons for this phenomenon have been suggested empirical evidence both supports and refutes insensitivity this paper presents data that suggest that insensitivity may be significantly determined by the individual s budget constraint the higher the proportion of income the expressed wtp represents the greater the insensitivity of that wtp to changes in the scale of the good irrespective of changes in underlying marginal utility the methodological implication for cv studies in health care is outlined

economics health and health economics hyes healthy years equivalent versus qalys quality adjusted live year this paper responds to culyer and wagstaff s cw and buckingham s b arguments we refute their claim about the equivalence of hyes and qalys they fail to distinguish between choice under uncertainty and under certainty cw assume that all individuals have a specific form of utility function which yields their conclusion of equivalence b s arguments confuse the measurement technique and the utility theory from which it stems his argument about the normative superiority of the qaly construct is inconsistent with economic thinking the hye by being compatible with the principles of economics is superior to the qaly for economic evaluations of health care interventions

time preference the discounted utility model and health the constant rate discounted utility model is commonly used to represent intertemporal preferences in health care program evaluations this paper examines the appropriateness of this model and argues that the model fails both normatively and descriptively as a representation of individual intertemporal preferences for health outcomes variable rate discounted utility models are more flexible but still require restrictive assumptions and may lead to dynamically inconsistent behaviour the paper concludes by considering two ways of incorporating individual intertemporal preferences in health care program evaluations that allow for complementarity of health outcomes in different time periods

alternative approaches to valuing intangible health losses the evidence for multiple sclerosis abstract this study uses both risk risk and risk dollar approaches to assess intangible health losses associated with multiple sclerosis ms using an estimation approach that adjusts for potential perceptional biases that may affect the expressed risk tradeoffs we estimated parameters of the utility function of persons with and without ms as well as the degree of subjects overestimation of the probability of obtaining ms the sample included subjects from the general population and persons with ms we found that marginal utility of income is lower in the state with ms than without it however the difference in marginal utility in the two states was greater for persons without ms than for those with the disease persons with ms overestimated the probability of acquiring ms to a greater extent than did persons within ms correcting for overestimation of this probability the value of intangible loss of a statistical case of ms derived from responses of the general population was us 350 000 to us 500 000 persons with ms were willing to pay somewhat more than this d80 i18 j17

eliciting preferences for collectively financed health programmes the willingness to assign approach improving public involvement in health system decision making stands as a primary health policy goal however still limited guidance is available on how best to elicit preferences for health care programmes this study examines a contingent choice technique to elicit preferences among health programmes and named willingness to assign wtas wtas reveals relative monetary based values of a set of competing public programmes under a hypothetical healthcare budget assessment experimental evidence is reported from a deliberative empirical study valuing ten health programmes in the context of the catalan health service evidence from this experimental study reveals that within the context of multiple programmes preferences are internally more consistent and slightly less affected by preference reversals as compared to values revealed from an adapted technique eliciting the willingness to pay wtp extra taxes another finding suggests that although programmes promoting health received the higher rel

pressure and the division of a public budget this paper considers the division of a public budget among competing interests the planner determines the optimal allocation by maximizing a weighted social welfare function these weights reflect society s attitudes to different recipient groups and are not constrained to be constant by exerting pressure the recipients can attempt to manipulate the weights and hence influence the division of the budget the amount of resources used on pressure and the effects on the preference weights are calculated an important parameter in the model is the elasticity of pressure for which an appropriate estimate is presented from the case of competition for a share of a health services budget in norway

applying conjoint analysis in economic evaluations an application to menorrhagia the increased demand for health care coupled with limited resources means that decisions have to be made concerning the allocation of scarce health care resources this paper considers how conjoint analysis ca can be used to aid this decision making process it is shown how the technique can be used to estimate marginal rates of substitution between attributes willingness to pay wtp if cost is included as an attribute and overall utility scores for different ways of providing a service the technique is applied to consider women s preferences for two surgical procedures in the treatment of menorrhagia hysterectomy and conservative surgery the results suggest conservative surgery is preferred to hysterectomy as indicated by higher utility scores for the former and a marginal wtp of 7593 to have conservative surgery rather than hysterectomy the internal validity of ca was also shown it is concluded that ca is a potentially useful instrument for policy makers however numerous methodological iss

a new approach to valuing a life abstract because the issue of how to put a monetary value on a life will always be controversial this paper presents an alternative approach that can in certain circumstances avoid the use of monetary values the alternative approach uses time as the numeraire this numeraire can handle both the ex ante and ex post approaches to valuing a life after showing how a simple two period consumer choice problem can be translated into terms of time the paper considers an application that involves reformulating the data used to evaluate the 55 mph speed limit decision in the united states

using rank data to estimate health state utility models in this paper we report the estimation of conditional logistic regression models for the health utilities index mark 2 and the sf 6d using ordinal preference data the results are compared to the conventional regression models estimated from standard gamble data and to the observed mean standard gamble health state valuations for both the hui2 and the sf 6d the models estimated using ordinal data are broadly comparable to the models estimated on standard gamble data and the predictive performance of these models is close to that of the standard gamble models our research indicates that ordinal data have the potential to provide useful insights into community health state preferences however important questions remain

a new axiomatic approach to the evaluation of population health in this paper we explore the implications of normative principles for the evaluation of population health we formalize those principles as axioms for social preferences over distributions of health for a given population we single out several focal population health evaluation functions which represent social preferences as a result of combinations of those axioms our results provide new rationale for popular theories in health economics such as the unweighted aggregation of quality adjusted life years qalys or healthy years equivalents hyes and generalizations of the two aimed to capture concerns for distributive justice without resorting to controversial assumptions on individual preferences

health utility indices and equity considerations the aim of this paper is to propose methods that incorporate equity concerns into cost utility analysis the focus of the paper is on qalys but the results apply to health utility indices in general two interpretations of qalys are considered qalys as von neumann morgenstern utilities and qalys as measures of health a justification is provided for aggregating consistently scaled qalys as utilities over individuals the conditions underlying unweighted aggregation of qalys are identified these conditions exclude two common types of equity concern algorithms are proposed that take into account equity concerns and that are relatively easy to apply

dynamic allocation of kidneys to candidates on the transplant waiting list the crux of the kidney allocation problem is the trade off between clinical efficiency and equity we consider a dynamic resource allocation problem with the tri criteria objective of maximizing the quality adjusted life expectancy of transplant candidates clinical efficiency and minimizing two measures of inequity a linear function of the likelihood of transplantation of the various types of patients and a quadratic function that quantifies the differences in mean waiting times across patient types the dynamic status of patients is modeled by a set of linear differential equations and an approximate analysis of the optimal control problem yields a dynamic index policy we construct a large scale simulation model using data from over 30 000 transplants and the simulation results demonstrate that relative to the organ allocation policy currently employed in the united states the dynamic index policy increases the quality adjusted life expectancy and reduces the mean waiting time until transplantation for all six demographic groups two sexes races and age groups under consideration

universal health insurance in the clinton plan coverage as a tax financed public good the financing arrangements embodied in the clinton health reform plan involve some important differences in the way in which public goods are usually financed the subsidies to small low wage firms mandated to provide benefits distort markets in both labor and products and offer incentives for the creation of small firms in addition the financing scheme implicitly envisions a head tax on families at modest income levels but offers a possible rationale for it nevertheless the main reason for many of the financing features appears to be an attempt to hold down the apparent budgetary cost of universal coverage

cost effectiveness utility analyses do current decision rules lead us to where we want to be despite the growing literature on economic evaluation of health care programmes little attention has been paid to the theoretical foundations of cost effectiveness and cost utility analyses and the validity of the decision rules adopted as methods of achieving the stated goals we show that although applications of the techniques can be used to pursue some managerial objectives in the context of highly constrained environments such applications are inconsistent with both welfare economic objectives and the interpretations of the findings of these applications alternative strategies are identified as potential and practical methods for pursuing welfare economic objectives

structural reliability of conjoint measurement in health care an empirical investigation this paper is concerned with the structural reliability of conjoint measurement when applied in a health care setting the clinical context was the diagnosis and treatment of knee injuries a conjoint measurement study was conducted which used the pairwise choice approach to preference elicitation each choice included two scenarios a conventional treatment approach to management arthroscopy and an approach using magnetic resonance imaging in order to test for structural reliability two separate conjoint measurement exercises were conducted exercise a where scenarios were defined in terms of three attributes and exercise b where scenarios included all four attributes the assessment of structural reliability involved a comparison of two random effects probit models for exercises a and b data were collected on a total of 176 students of sports science the results strongly indicate that the models for the two exercises are different although the instability is limited to the constant term and a sin

valuing health care using willingness to pay a comparison of the payment card and dichotomous choice methods this paper compares willingness to pay wtp estimates generated from the dichotomous choice dc and payment card pc approaches in a split sample wtp experiment concerned with allocating scarce health care resources across three health care interventions the dc approach is shown consistently to generate larger welfare estimates than the pc observed difference between pc and dc experiments cannot be explained by the inclusion of non demanders or methods of statistical analysis but may be partly explained by yea saying no evidence of range bias or mid point bias was found with pc responses data were also collected on respondents ordinal rankings of the three interventions and person trade offs ptos neither of these approaches converged with wtp future work must address the decision heuristics individuals employ when responding to valuation experiments

equity considerations in utility based measures of health outcomes in economic appraisals an adjustment algorithm in this paper we consider whether methods currently used to measure utility of health outcomes are consistent with the equity criteria adopted by researchers we show that unless the chosen equity criterion is incorporated in the design of the measurement instrument the derived health state utilities are inconsistent with the equity criterion except under special circumstances adjustment algorithms are derived based on the axioms of von neumann morgenstern utility theory which take account of difference equity criteria currently adopted in the literature the proposed approach is based on simple lottery questions of the type already used widely in empirical studies

on the economic foundations of cea ladies and gentlemen take your positions abstract there are still many ongoing debates about several aspects of the methodology of economic evaluations of health care interventions some of the disparities in recommendations on methodological issues may be traced back to different viewpoints on cost effectiveness analysis cea in general two important views are the welfarist approach which aims at embedding cea into traditional welfare economics and the decision maker s approach which takes a broader and more pragmatic view on cea the focus in welfarism may be on utility while that of the decision maker s approach may be considered to be on health in this paper it is examined how these two views differ and how these differences may subsequently lead to debates in methodological areas it is indicated that embedding the practical operationalisation of cea in welfare economics seems impossible in a strict welfarist approach it is necessary to view qalys as being utilities although one may question whether such an approach to qalys is appropriate also equity considerations may play an important role in cost effectiveness analysis and these should preferably be taken into account in a way that reflects societal attitudes towards an equitable distribution of health care these equity considerations may not always be directly related to utility or efficiency furthermore both camps may prefer different methods for cost measurement in areas such as productivity costs and informal care a better recognition of the contents and origins of controversies and disputes may enhance the clarity of discussions

applications of cost benefit analysis to health care departures from welfare economic theory in applying the principles of cost benefit analysis to real world problems of resource allocation particular care must be taken to ensure that the welfare economic theory which underlies the cost benefit technique is adhered to major problems arise where costs and benefits are used interchangeably to represent the good and bad attributes of a programme furthermore in the presence of mutually exclusive projects focussing attention upon the net benefits or cost benefit ratios of individual projects as opposed to the net benefits of the use of budgeted resources can lead to biased estimates of the shadow price of projects and consequently errors in analysts conclusions as a result economic appraisals of individual projects are not directly relevant for choosing between mutually exclusive projects of different sizes both types of problem are illustrated by reference to both simple examples and published economic appraisals of health care techniques integer programming is proposed and demonstrated as a method of selecting between mutually exclusive projects

qalys versus hyes this paper explores the claim that qalys are liable to misrepresent consumer preferences and hence lead to decision makers choosing options which are not those preferred by the public it also considers the claim that hyes do not suffer from this defect we argue that none of the examples offered to date demonstrate the alleged tendency of qalys to misrepresent preferences we also show that hyes are identical to qaly scores obtained from a time tradeoff experiment and therefore that the assumptions about preferences underlying hyes are just as restrictive as those underlying tto based qalys

sequencing and nesting in contingent valuation surveys abstract the term embedding is ill defined and has been applied to distinct phenomena some predicted by economic theory and others not this paper lays out a theoretical framework for looking at these phenomena and provides a set of well defined terms included is a discussion of survey design problems which may induce spurious evidence in favor of the hypothesis that respondents are insensitive to the scope of the good being valued an empirical example of the component sensitivity is provided this test rejects the hypothesis that respondents are insensitive to the scope of the good being valued

on the aggregation of health status measures in the present paper we address the problem of finding conditions under which aggregation of individual health status measurements e g qalys is meaningful in the sense that there is a universal unit of measurement for health the problem is studied in a model where different aspects of health take the form of lancasterian characteristics to be produced by the individuals using commodities obtained in the market for a meaningful unit of measurement to exist marginal rates of substitution between different aspects of health should not differ among individuals and for this to happen in an equilibrium of the economy considered certain assumptions of separability of technology and or preferences must be satisfied this means that universal measures of health will be meaningful only if there are not too many spillovers in achieving different aspects of health

ethics in finance and public policy the ibercorp case our research has found that companies which have diverged from traditional management in order to adopt strategies which include ethics cooperation and a joint vision of management obtain a greater added value the new challenges of competitiveness require a position of active cooperation between firms and their suppliers which should be considered as collaborators rather than adversaries an active cooperation management may well allow the company to improve the quality of its products and its image speed up delivery to its clients and make its production and trading more agile thus enhancing the perception the client has of the product an improved ethical quality in our dealings generating trust improving communication and establishing long term relationships with joint added value results in higher competitiveness and greater creation of wealth

how people respond to contingent valuation questions a verbal protocol analysis of willingness to pay for an environmental regulation abstract this paper investigates what a respondent is thinking when answering a willingness to pay question in a contingent valuation using a think aloud technique from psychology called verbal protocol analysis the willingness to pay responses we observed seem to be constructed from a variety of considerations including an obligation to pay a fair share of the cost of the solution and signaling concern for a larger set of environmental issues the finding that respondents seem to construct their values at the time they are asked rather than reporting a more well defined value is seen as consistent with over two decades of research on the psychology of decision making potential uses of verbal protocols in contingent valuation studies are also discussed

tiered housing markets and their relationship to labour market areas this paper develops a tiered geography of local housing market areas hmas that provides a national framework for spatial planning it is derived from a theoretical understanding of the economic basis of hmas the analysis explores the relationships between the tiers of the hma geography and local labour market areas drawing on this understanding the empirical research generates sets of different potential geographies of hmas for england based on an algorithm that applies criteria linked to the degree of closure of migration and or commuting patterns a range of theoretically appropriate criteria then enable the different geographies to be assessed the choice of geography is guided by chow tests of statistical differences in standardised house prices in neighbouring hmas derived from hedonic regressions finally conclusions are drawn on the validity of the approach developed the empirical work is on england and datasets drawn from the census and land registry

accounting for future costs in medical cost effectiveness analysis most medical cost effectiveness analyses include future costs only for related illnesses but this approach is controversial this paper demonstrates that cost effectiveness analysis is consistent with lifetime utility maximization only if it includes all future medical and non medical expenditures estimates of the magnitude of these future costs suggest that they may substantially alter both the absolute and relative cost effectiveness of medical interventions particularly when an intervention increases length of life more than quality of life in older populations current methods overstate the cost effectiveness of interventions which extend life compared to interventions which improve the quality of life

valuing morbidity an integration of the willingness to pay and health status index literatures placing dollar values on human health has long been a controversial aspect of policy analysis and remains difficult given the relatively small number of morbidity valuation studies available by combining both the economic and health literature this paper offers an alternative approach to morbidity valuation and provides estimates for a wide range of short term health conditions

the definition of housing market areas and strategic planning the purpose of this paper is to develop the concept of a housing market area thereby provide insights into our understanding of the sub regional structures of the housing system and hence propose a framework for strategic planning research in the housing market to tackle this task it is first necessary to consider the criteria for a local housing market area the paper begins by reviewing previous definitions by both academics and planners and their underlying assumptions based on the principle of spatial arbitrage a local housing market area is defined by reference to criteria linked to migration self containment parallels are drawn with the principles that have been applied to define a system of spatial labour markets using travel to work areas this spatial arbitrage definition is tested empirically by developing a system of housing market areas for west central scotland using data derived from the land registry finally the paper draws together the empirical findings to discuss the nature of s

using a discrete choice experiment to estimate health state utility values in this study we explored a novel application of the discrete choice experiment dce that resembles the time trade off tto task to estimate values on the health utility scale for the eq 5d the dce was tested in a survey alongside the tto in a sample of english speaking canadians recruited by a market research company the study found that the dce is able to derive logical and consistent values for health states valued on the full health dead scale the dce overcame some issues identified in the version of tto currently used to value eq 5d notably allowing for fewer data exclusions and incorporating values considered worse than dead without introducing a separate valuation procedure this has important implications for providing robust values that represent the preferences of all respondents

models of quality adjusted life years when health varies over time survey and analysis quality adjusted life year qaly models are widely used for economic evaluation in the health care sector in the first part of the paper we establish an overview of qaly models where health varies over time and provide a theo retical analysis of model identification and parameter estimation from time trade off tto and standard gamble sg scores we investigate deterministic and probabilistic models and consider five different families of discounting functions in all the second part of the paper discusses four issues recurrently debated in the literature this discussion includes questioning the sg method as the gold standard for estimation of the health state index re examining the role of the constant proportional trade off condition revisiting the problem of double dis counting of qalys and suggesting that it is not a matter of choosing between tto and sg procedures as the combination of these two can be used to disen tangle risk aversion from discounting we find that caution must be taken when drawing conclusions from models with chronic health states to situations where health varies over time one notable difference is that in the former case risk aversion may be indistinguishable from discounting models of quality adjusted life years qalys are widely used as health related quality of life measures for economic evaluation in the health care sector in its simplest form the qaly approach assumes that the utility of a profile of health states over time may be estimated by adding the values of the constituent health states in the health profile in more sophisticated models health events occurring in the future may be discounted or risk adjusted

measurement of health state utilities for economic appraisal health status measurement for use in economic appraisal of health care programmes is reviewed in this paper with particular emphasis on utility measurement a framework for economic appraisal is presented displaying the various components that must be measured and showing how the three forms of analysis cost effectiveness analysis cost benefit analysis and cost utility analysis relate to the framework and to each other one of the components in the framework is health status it can be measured using ad hoc numeric scales willingness to pay receive or health state utilities the determination of health state utilities is reviewed covering the following issues alternative sources of utilities health state descriptions multi attribute utility approach determination of appropriate subjects utility aggregation and accuracy three measurement techniques for health state utilities are described in detail rating scale standard gamble and time trade off the use of these methods is described for both chronic and temporary health states and for both health states considered better than death and those considered worse than death

incorporating psycho social considerations into health valuation an experimental study abstract this study used multiple elicitation question modes and group discussions to value psycho social considerations associated with public perceptions of health risks values for saving 100 statistical lives in six different policy contexts varied by 50 largely due to psycho social considerations of choice and control a currency effect was found value of life differentials were smaller when questions were framed directly in the currency of lives saved rather than willingness to pay or public spending to save lives discussions reduced but did not eliminate inconsistencies and slightly increased the relative valuations of health interventions involving less choice and control by those at risk

imprecise preferences and survey design in contingent valuation during recent years the contingent valuation cv method has been widely used to value non marketed goods and services we present the results of a cv study of the value of road safety we find that stated preferences for road safety exhibit considerable imprecision appear subject to various systematic biases and are insensitive to variations in the quantity and quality of the safety improvements concerned one broad implication of these findings may be that for an important class of goods of which safety is one example standard assumptions about the structure of people s preferences may be much too strong a more specific implication concerning the design and conduct of cv surveys is that the noaa panel s widely cited blueprint for good cv practice may rely far too heavily on assumptions about the precision and sensitivity of people s preferences

commuting migration housing and labour markets complex interactions commuting migration housing and labour markets are important for the overall economy and for the everyday life of many people commuting makes up a large part of all journeys world wide and many resourcedemanding transport investment projects are initiated to cope with this type of travelling in a range of countries increasing flows of national and international migration are central determinants of demographic developments in industrialised countries the working age population or those aspiring to be part of the economically active population constitute a large proportion of the total population consequently income earned through working represents a major component of total earnings in these economies cahuc and zylberberg 2004 in order to obtain an efficient labour market workers should locate and relocate to where the relevant jobs are to be found from an economic point of view commuting and migration are essential elements for obtaining a well functioning labour market fischer et al 1996 lux and sunega 2012 zabel 2012 finally housing is a basic good and for many people rents or loan repayments make up a relatively large proportion of their overall budget oecd 2011 moreover housing represents a dominating element of homeowners wealth or equity due to its central role during the financial and economic crisis starting around 2007 it has become clear that housing prices are important for the development of the overall economy in many countries for example muellbauer and murphy 2008 zabel 2012 housing and labour markets are linked in many ways when explaining these links it is useful to start with some of the distinguished features of housing markets as already mentioned houses frequently constitute a major part of households wealth moreover earned income from employment is a major

stakeholder learning dialogues how to preserve ethical responsibility in networks the shift in corporate strategy from vertical integration to strategic alliances has developed hand in hand with the evolution of organizational structure from the vertically integrated firm to the network organization the result has been the elimination of boundaries more flexible organizations and a greater interaction among individuals and organizations on the negative side the specialization of firms on single areas of competence has resulted in the disaggregation of the value chain and in the disaggregation of ethical and legal responsibility to illustrate this point the paper considers some cases such as the case of the beer girls of southeast asia who are used unethically by distributors to sell beer and liquor to deal with the problem of the disaggregation of ethical responsibility managers can use organizational culture and ethical values to control the performance of employees and of other organizations contemporary developments in business ethics also offer tools for dealing with the problem for example global corporate citizenship integrated social contracting theory and stakeholder learning dialogues provide ways of integrating the interests of all stakeholders the task is now to use these new approaches to create a governance process that incorporates the voices of all stakeholders especially the voices of those stakeholders that have legitimate and urgent moral claims but lack the power to establish those claims

economic evaluation of services for a national health scheme the case for a fairness based framework in this paper we argue that the usual framework for evaluating health services may need modification in the context of a national health scheme nhs some costs and benefits may need to be ignored or discounted others included at face value and some transfer payments included in the decision algorithm in contrast with the standard framework we argue that economic evaluation in the context of an nhs should focus on social transfers between taxpayers and beneficiaries and that the nature and scope of these transfers is determined by the level of social generosity some of the implications of a modified framework are illustrated with a re examination of i costs and transfer payments ii unrelated future costs iii moral hazard and iv the rule that marginal costs should equal marginal benefits we argue that an explicitly fairness based framework is needed for the evaluation of services in an nhs in contrast the usual welfare economic theoretic framework facilitates the sidelining of issues of fairness

ethical and moral dilemmas associated with strategic relationships between business to business buyers and sellers while ethical and moral issues have been widely considered in the general areas of marketing and sales similar attention has not been given to the impact of strategic account management sam approaches to handling the relationships between suppliers and very large customers sam approaches have been widely adopted by suppliers as a mechanism for managing relationships and partnerships with dominant customers characterized by high levels of buyer seller inter dependence and forms of collaborative partnership observation suggests that the perceived moral intensity of these relationships is commonly low notwithstanding the underlying principles of benefiting the few large strategic customers at the expense of the many smaller customers and other stakeholders and the magnitude of the consequences of concessions made to large customers even though some such consequences may be unintended dilemmas exist also for executives implementing strategic account relationships regarding such issues as information sharing trust and hidden incentives for unethical behaviour we propose the need for greater transparency and senior management questioning of the ethical and moral issues implicit in strategic account management

qalys versus hyes what s right and what s wrong a review of the controversy abstract the paper uses an axiomatic approach to the description of individual preferences for health status sequences to resolve the major issues at stake in the recent controversy over qalys versus hyes while the hye accounts for an individual s time preference for health qaly scores based on the time trade off method will generally differ from the number of hyes hyes do not represent preferences for health under risk unless the utility function for reference flows of health is linear collapsing the two step hye assessment procedure into a single step entails a loss of information as regards the utility of a health status sequence although the procedure does represent preferences for health it fails to supply a description in terms of hyes in the case of risk as a remedy a modified hye approach is proposed

qualitative valuation of environmental criteria through a group consensus based on stochastic dominance abstract this paper introduces a qualitative valuation method to elicit stakeholders intensities of preferences for a complex environmental issue and multiple social groups environmental valuation studies have shown that in any complex environment with a diversity of environmental services stakeholders have difficulties using a monetary valuation to make trade offs between different environmental services stated preference methods such as the contingent valuation method cvm have been criticised for their individualistic format and assumptions of commensurability between environmental criteria to alleviate both of these criticisms we propose a qualitative valuation method the method contains a discursive step to allow stakeholders to discuss and construct a list of environmental criteria and alternative plans the list of criteria and plans is subsequently used by a group of experts to formulate an impact matrix im which is to be used in the succeeding individualistic steps of the methodology the first individualistic step consists of asking the stakeholders to rank alternative impacts ais in the im for each single criterion the stakeholders are then asked to express intensities of their preferences through pairwise comparisons between the ais of the constructed rank order on each single criterion these intensities are expressed on a qualitative scale subsequently to provide social intensities of preferences a social preference social rank order is first determined for each single criterion we propose to use the median value among the intensities of preferences as the social intensity of preference by assuming interpersonal comparability and taking into account stochastic monotonocity this is a pre processing step which allows us to reach social intensities of preferences in the lar rangeland iran where several social groups have conflicting interests on rangeland services leading to conflicting preferences on environmental criteria

valuing environmental health effects an economic perspective this paper provides an overview of some of the issues involved in comparing benefit cost analysis and cost effectiveness analysis based on quality adjusted life years as alternative approaches to assessing environmental policies that affect human health it concludes that i although qalys have the advantage of reflecting policy impacts on both health status and longevity in a single scalar measure they are not consistent with utility theory unless individuals preferences satisfy some restrictive conditions ii they do not capture other important aspects of the valuation of changes in mortality and morbidity iii cost effectiveness analysis based on qalys as a measure of effectiveness omits non health related effects of environmental policy and iv it leaves unanswered the important question of what level of environmental regulation is appropriate
