arbitrary values good causes and premature verdicts abstract this paper offers an alternative interpretation of the conclusions kahneman and knetsch propose based on two contingent valuation cvm surveys the evaluation argues that while framing is important to cvm estimates the design implementation and empirical findings reported from these surveys do not support their judgments moreover with the exception of temporal embedding conventional economic descriptions of individual behavior can explain the response patterns that they suggest are at variance with standard value theory

optimal prices for alpine ski passes abstract the purpose of this paper is to examine the relationship between price and demand and to determine the effect of variable pricing on ski resort revenues we use data from a survey of existing skiers at three ski resorts in the inland region of norway to estimate price response functions based on a number of characteristics including day of week and distance to the resort the various price response functions are subsequently used to calculate optimal prices for each subset of skiers according to their differing characteristics the results show that ski resorts have the potential to increase their total revenues substantially by adopting a more dynamic approach to pricing thus our results provide academic support for the findings of ski resorts that have implemented such pricing strategies

privately operated water utilities municipal price negotiation and estimation of residential water demand the case of france this paper addresses the issue of price negotiation between a municipality and a private water utility operator and its implications for residential water demand estimation we use appropriate econometric procedures to estimate a water demand equation on a panel of french municipalities we find evidence that negotiated water price depends on municipality s characteristics causing endogeneity of price in the demand equation the impact of average household income housing and system features such as metering is investigated both on municipal consumption and price estimated price and income elasticities are significant and close to previous household level studies

testing for the survey mode effect on contingent valuation data quality a case study of web based versus in person interviews this paper addresses the lack of empirical evaluation of the use of web based surveys in the context of contingent valuation surveys we compare using a case study in person interviews with web based surveys regarding response rate information additivity effects and respondents attitudes towards paying the web based survey had a much lower response 5 1 than the in person interviewing 84 we find the web based contingent valuation surveys to be neither more susceptible to information additivity effects nor more prone to zero protest responses we conclude in favor of the use of web based surveys namely in portugal where the number of internet users is rapidly increasing although further research efforts are required on their use

toward a political theory of the emergence of environmental incentive regulation this article makes some steps toward a formal political economy of environmental policy economists quasi unanimous preference for sophisticated incentive regulation is reconsidered we recast the question of instrument choice in the general mechanism design literature within an incomplete contract approach to political economy we show why constitutional constraints on the instruments of environmental policy may be desirable even though they appear inefficient from a standard economic viewpoint their justification lies in the limitations they impose on the politicians ability to distribute rents insights are provided on the emergence of incentive mechanisms in environmental regulation

rewards to academia the remuneration of vice chancellors and principals this paper models the financial remuneration to vice chancellors and principals at uk higher education institutions after describing the alternative theoretical underpinnings for the determination of pay an earnings function is estimated utilizing institutional and personal characteristics the model suggests only a partial linkage of managerial and performance related indicators to remuneration levels this suggests substantial scope for reorientation of rewards towards such indicators rather than relying on an efficiency wage this would appear particularly appropriate given the present and continued disclosure of this information together with the increased focus on performance indicators relating to teaching and research within the uk higher education sector

imagined risks and cost benefit analysis everyone recognizes substantial discrepancies between the public s rankings of hazards and those of the experts for example experts at the environmental protection agency think that hazardous waste sites pose mediumto low risks to the public while indoor air pollution poses a high risk yet public perceptions have driven policy to focus on hazardous waste sites rather than on indoor air quality stephen breyer 1993 pp 19 20 whose beliefs should determine government policy when the public s beliefs differ from those of the experts the problem evaporates if the public perhaps recognizing its inability to deal with complex technical issues entrusts risk assessment to the government and its experts but what if the public perhaps distrusting government and experts is unwilling to leave risk assessment to the experts paul portney 1992 p 131 posed a version of this whose beliefs question succinctly in his fable trouble in happyville

studying optimal paternalism illustrated by a model of sin taxes the classical economic approach to policy analysis assumes that people always respond optimally to the costs and benefits of their available choices a great deal of evidence suggests however that in some contexts people make errors that lead them not to behave in their own best interests economic policy prescriptions might change once we recognize that humans are humanly rational rather than superhumanly rational and in particular it may be fruitful for economists to study the possible advantages of paternalistic policies that help people make better choices we propose an approach for studying optimal paternalism that follows naturally from standard assumptions and methods of economic theory write down assumptions about the distribution of rational and irrational types of agents about the available policy instruments and about the government s information about agents and then investigate which policies achieve the most efficient outcomes in other words economists ought to treat the analysis of optimal paternalism as a mechanism design problem when some agents might be boundedly rational this approach has many advantages first and foremost by explicitly addressing when and how people do and don t pursue their own best interests economists will be better able to contribute to policy debates to contribute to debates over regulating private financial decisions we must study whether financial decisions are based on fallacious statistical reasoning and whether self control problems lead people to borrow too heavily to contribute to debates over teenage smoking we must study whether teenagers become smokers against their long run best interest economists will and should be ignored if we continue to insist that it is axiomatic that constantly trading stocks or accumulating consumer debt or becoming a heroin addict must be optimal for the people doing these things merely because they have chosen to do it a second advantage of our approach is that it forces us to look for the best feasible policy our

buyer symmetry in monopoly abstract for a price setting monopolist the aggregate demand curve sufficiently summarizes the demand environment the distribution of demand namely how the demand is distributed among the buyers is not relevant but intuitive notions of strong versus weak buyers suggest that the distribution of demand should be relevant to a monopolist this paper provides a formal justification for such notions using cooperative game theory to model monopoly without an a priori assumption of price setting power the paper shows that a seller will always prefer unitary demand thus implying that the demand distribution does affect how a monopolist assesses the demand environment furthermore if the number of buyers is kept fixed a seller always prefers that when feasible the buyers be symmetric namely that they have the same individual demand curves this result holds for all capacity choices of the seller implying that buyer symmetry is always the most preferred distribution of demand

creating monopoly power abstract the standard analysis of monopoly assumes that the seller has price setting power without this assumption it is not clear what monopoly power is or whether it exists to address this question this paper uses the core of a tu game in place of price setting the core provides a model of competition in which outcomes can be interpreted as the consequences of free form bargaining or negotiations this paper shows that if a core analysis is embedded in a capacity choice context monopoly power can be created with credible undersupply but in monopoly a core analysis also shows that competition only partially determines the outcomes using a biform game analysis this paper shows that the monopolist s view of this indeterminacy directly affects its capacity choice a moderate view of the indeterminacy generates outcomes that are more socially beneficial than setting a uniform price the two extreme views of the indeterminacy are shown to generate results consistent with uniform pricing and perfect price discrimination

how do value creation and competition determine whether a firm appropriates value how does competition among economic actors determine the value that each is able to appropriate we provide a formal general framework within which this question can be posed and answered and then provide several results chief among them is a condition that is both required for and guarantees value appropriation we apply our methodology to i assess the familiar notion that uniqueness inimitability and competition imply value appropriation and ii determine the value appropriation possibilities for an innovator whose unique discovery is of use to several others who can compete for the right to use it

what does a university add to its local economy the local multiplier effects of a university are estimated using data for the university of nottingham gross output and disposable income multipliers are calculated the latter are adjusted to exclude the incomes of induced migrants whose welfare is assumed unchanged

on the contingent valuation of mortality risk reduction in developing countries using the contingent valuation method in developing countries to value mortality risk reduction is particularly challenging because of the low level education of the respondents in this article we investigate whether some brief training regarding probability and risk concepts has any significant effect on the willingness to pay wtp responses we elicit individuals risk perceptions by providing information on age specific mortality risks and find that people on average overestimate the mortality risk at younger ages and underestimate it at older ages our results indicate a significantly higher wtp for the trained sub sample and wtp is sensitive to the magnitude of risk reduction for both the sub samples

residential willingness to pay for deep decarbonization of electricity supply contingent valuation evidence from hong kong abstract motivated by the government s proposed target of reducing co2 emissions by 30 of the 2005 level in the year 2020 we estimate the residential willingness to pay wtp for deep decarbonization of hong kong s electricity supply which is heavily dependent on coal fired generation our contingent valuation survey conducted in 2016 of 1460 households yields dichotomous choice data based on the respondents answers to a series of closed ended questions such data are less susceptible to the strategic bias that often plagues self stated wtp data obtained by direct elicitation via open ended questions using binary choice models we find that average wtp is 48 51 relative to current bills if the decarbonization target is achieved via natural gas generation and renewable energy however estimated wtp declines to 32 42 when decarbonization entails additional nuclear imports from china as the projected bill increase caused by the target s implementation is 40 our wtp estimates support the government s fuel mix policy of using natural gas and renewable energy to displace hong kong s coal generation

consumers preferences for the attributes of post pc results of a contingent ranking study with the explosive growth of the internet and the change in consumer demand post pc is emerging as a substitute for the existing desktop pc and laptop pc post pc is a new computer which is portable with wireless networking cheaper than the existing pc and specializing in the specific functions that consumers want rudimentary post pcs such as pda web pad and smart phone are already in use in the future owing to technological progress the heterogeneity of related companies and the low entry barrier various post pcs will be developed this paper attempts to analyse consumers willingness to pay wtp for post pc with such attributes as portability cpu speed data input method using key board or electric pen monitor size and price to this end a contingent ranking method is applied which makes the respondents rank hypothetical post pc alternatives featuring various combinations of attributes via a survey data collected in korea using the estimated wtp the shape and the capacity of future po

faculty support for the objectives of university industry relations versus degree of r d cooperation the importance of regional absorptive capacity abstract the growing importance of regions in the analysis of innovation and the pressure on european universities to interact with their environment justify this article it argues that faculty support for the objectives of university industry relations uir does not vary across disciplines and does not respond to university encouragement in a region with low absorptive capacity these results are in contrast with those obtained in studies of technology leading countries like the usa furthermore incentives for uir may generate unpredicted dynamics while instruments to cooperate are not significant finally support for the objectives of uir should not be confused with the degree of r d cooperation the former is sensitive to university age while the latter is sensitive to gender discipline commitment to r d and university encouragement empirical evidence is obtained from a sample of faculty from the valencian community spain and analysed through a set of models for discrete choice

regulation in happyville how does risk perception affect risk regulation happyville is a society in which citizens wrongly believe that the drinking water supply is contaminated we discuss conditions under which a benevolent director of environment protection would invest in a water cleanup technology this holds if the director is populist namely if he maximises social welfare based on citizens pessimistic beliefs more surprisingly investment in the water cleanup technology may occur if the director is paternalistic in the sense that he maximises social welfare based on his own beliefs the reason is that he must take into account citizens responses to regulation

your money or your life green growth policies and welfare in 2050 this paper proposes a simple index of economic progress that weighs in the monetary cost induced by climate change mitigation policies as well as the health benefits arising from the reduction in local air pollution the shadow price of pollution is calculated indirectly through its impact on life expectancy taking into account the health benefits of mitigation policies significantly reduces their monetary cost in china and india as well as in countries with large fossil based energy producing sectors australia canada and the united states

valuing public goods with the contingent valuation method a critique of kahneman and knetsch the social stakes in the use and abuse of the contingent valuation method cvm are very high recent developments in environmental law have elevated the cvm to the status of a refutable presumption in cases brought under certain statutes it is no longer adequate for economists to sniff at the continued popularity of the cvm in such cases it is instead incumbent on economists to come to some conclusions as to the domain under which the cvm may or may not be correctly applied one should not expect a simple thumbs up or thumbs down assessment in this matter such an expectation would be naive with respect to the inherent complexity of the issue not to mention the financial incentives that expert witnesses might have to breed as if controversy in an adversarial legal system in this context the strong admonitions of kahneman and knetsch 3 kk against the casual use of the cvm must be carefully examined they present what they believe to be evidence to support the claim that the cvm suffers from an embedding effect and that any reported willingness to pay wtp is best interpreted as the purchase of moral satisfaction rather than as a measure of the value associated with a particular public good i argue that their evidence is insufficient to test the implied hypotheses that it is incorrectly reported and that it is in large measure fully consistent with received economic theory

willingness to pay entrance fees to natural attractions an icelandic case study abstract introducing entrance fees to natural attractions may help counteract the threat of inadequate public funds for site maintenance and management the primary objective of this study is to measure visitors willingness to pay such fees in iceland where no such measurement has previously been undertaken a questionnaire survey based on the contingent valuation method was carried out at two major natural attractions in iceland gullfoss waterfall and skaftafell national park over 92 of the 252 respondents were willing to pay an entrance fee mean amounts and population consumer surplus estimates per season were isk 1 333 and isk 41 million at gullfoss and isk 508 and isk 34 million at skaftafell respectively modest fees would not significantly decrease the demand for these attractions slight differences were found in the willingness to pay according to income attitude towards environmental protection number of previous visits history of paying entrance fees country of residence age and education implications of the empirical study for policy makers and site managers are provided

limits to substitution between ecosystem services and manufactured goods and implications for social discounting this paper examines implications of limits to substitution for estimating substitutability between ecosystem services and manufactured goods and for social discounting based on a model that accounts for a subsistence requirement in the consumption of ecosystem services we provide empirical evidence on substitution elasticities we find an initial mean elasticity of substitution of two which declines over time towards complementarity we subsequently extend the theory of dual discounting by introducing a subsistence requirement the relative price of ecosystem services is non constant and grows without bound as the consumption of ecosystem services declines towards the subsistence level an application suggests that the initial discount rate for ecosystem services is more than a percentage point lower as compared to manufactured goods this difference increases by a further half percentage point over a 300 year time horizon the results underscore the importance of considering limited substitutability in long term public project appraisal

is the income elasticity of environmental improvements less than one we estimated the income elasticity of environmental improvements for a number of european data sets the value of this parameter is consistently found to be less than one with few exceptions our findings are compared with state of the art contingent valuation studies from other countries we also compared our findings with those reported in the literature on charitable donations and corporate donations these studies show a similar pattern donations decrease as a percentage of income as income increases

the contingent valuation debate why economists should care t he contingent valuation method involves the use of sample surveys questionnaires to elicit the willingness of respondents to pay for generally hypothetical projects or programs the name of the method refers to the fact that the values revealed by respondents are contingent upon the constructed or simulated market presented in the survey a spirited and occasionally mean spirited battle over such methods is currently being waged involving competing factions within the federal government economists and lawyers representing business and environmental groups and interested academics as well at issue is a seemingly quite specific question should environmental regulations currently under development at both the department of the interior and the department of commerce sanction the use of the contingent valuation method in estimating the damage done by spills of oil chemicals or other substances covered by federal law more generally the debate raises broad questions about what economists have to say about the values that individuals place on public or private goods the two papers that follow this one make cases for and against the use of the contingent valuation method my aim here is to provide an overview of the technique and the debate surrounding it i also want to suggest why this debate should matter to economists both professionally and in their roles as citizens and consumers

paying for mitigation a multiple country study a contingent valuation study conducted in china sweden and the united states was used to investigate citizens willingness to pay wtp for reducing co2 emissions we find that a majority of the respondents in all three countries believe that the mean global temperature has increased over the last 100 years and that humans are responsible for the increase the share of americans that believes these statements is smaller and a relatively larger share of americans also believes that nothing can be done to stop climate change sweden has the highest wtp while china has the lowest jel q51 q54

altruism in cost benefit analysis it has recently been argued that altruistic motives for paying for a public sector project should be ignored in a cost benefit analysis the reason is that including altruism would mean a kind of double counting of the project s benefits this paper takes a look at these arguments and derives cost benefit rules which cover different kinds of altruism the paper also provides some recommendations for the treatment of altruism in studies using the contingent valuation method

bilateral monopolies and incentives for merger the paper presents a model of duopoly in which firms acquire inputs through bilateral monopoly relations with suppliers it combines a bargaining model with a duopoly model to examine how input pri

what matters most teaching or research empirical evidence on the remuneration of british academics this paper examines the impact of productivity on pay within academia drawing upon a detailed dataset of academics from five old established universities results outline the importance of publication grant receipt and teaching quality in the determination of pay a large financial penalty to time out of the profession is revealed which with productivity variables explains away the gender salary gap the relationship between teaching and research is investigated and we find some evidence in support of the hypothesis that productive researchers are successful teachers results on reservation salary suggest that the best academics are willing to stay within the profession

optimal incentives for income generation in universities the rule of thumb for the compton tax abstract in this paper we propose a novel framework to model one of the key links between universities and industry the undertaking of applied research we postulate that a basic objective of universities is to undertake fundamental research and that they receive public funding to do so nevertheless faced with tight budget constraints universities may have incentives to allow their staff to devote some of their time to income generating activities such as applied research or consultancy this opens up two channels by which universities can ease their budget constraint i by allowing academics to supplement their income universities may be able to hold down academic salaries ii universities can effectively tax the income that academics raise through applied research or consultancy for example through the imposition of overhead charges by easing their budget constraint universities may be able to take on sufficient extra staff to more than offset the time that existing staff are spending on non fundamental research and thus increase the amount of fundamental research that they can achieve with a given public budget we develop a model of this link between universities and firms and use it to determine the optimal tax that universities should impose on applied research income the compton tax used at mit in the 1930s is an early example of the use of this instrument

how beliefs influence the willingness to contribute to prevention expenditure we study how beliefs affect individuals willingness to contribute to prevention expenditure through a two type n person public good game and test several results empirically we show analytically that pessimistic agents will invest more in prevention expenditure than optimists we also demonstrate how small differences in beliefs may induce substantial differences in type related prevention expenditure the more atomistic agents are the less they will contribute to the public good pessimistic beliefs then lead to a double deprivation and we discuss potential issues and remedies the more optimistic a society is the lower will be its total green expenditure we then use a large international survey to study how beliefs and additional controls determine prevention expenditure we rely on several proxies for beliefs and the willingness to contribute to prevention expenditure which we combine through principal component analysis in addition we investigate the role of environmental education for the relationship between beliefs and the willingness to contribute because of potential endogeneity bias due to unobserved variables that are likely to affect both beliefs and the willingness to contribute we follow the theoretical analysis and resort to a recursive bivariate model our main findings are very much in line with the theoretical predictions we find across all specifications that more optimistic beliefs lead to a lower willingness to contribute environmental education affects the willingness to contribute only indirectly through its impact on beliefs

are french consumers ready to pay a premium for eco labeled seafood products a contingent valuation estimation with heterogeneous anchoring could the future french eco label for fresh seafood products find its place in the french market this study employs a contingent valuation method to estimate french consumers willingness to pay wtp for eco labeled fresh seafood products we exploit original data from a survey carried out in 2010 where 626 participants responded to a double bounded dichotomous choice model through an ascending or descending bid system controlling for shift and anchoring effects in random effect probit models we significantly improve estimation of wtp and its determinants for the three species studied monkfish lobster sole in particular when using heterogeneous anchoring we show that wtp is positively correlated to respondents income and also to their environmental concern to living alone to living far from the coast and to trusting ngos or public institutions more than producer organizations to implement an eco label we also show that the mean price premiums do not differ between species finally on average the maximum premium consumers accepted to pay is approximately 10 of the product price

willingness to pay for improved air quality in sweden the aim of the paper is to quantify individual willingness to pay measures of improved air quality in sweden by using the contingent valuation method cvm such measures are important for policy makers when deciding about public investments and policy instruments in order to regulate environmental impacts e g from road transportation and industry the mean willingness to pay wtp for a 50 reduction of harmful substances where the respondents live and work was about 2000 sek year which is of the same order of magnitude as earlier stated preference studies in nordic countries most parameters in the econometric analysis had the expected sign wtp was increasing in income wealth and education it was larger for men members of environmental organizations people living in big cities which are on average more polluted and people who own their house or apartment it was lower for retired people however the additional wtp for people in big cities although significantly higher than for other people

aggregation and deliberation in valuing environmental public goods starting from a distinction between kantian principle based and utilitarian preference based approaches in political theory this essay argues that we may understand normative judgments individuals make about policy to express principled views of the public interest or purpose not private preferences about their own consumption opportunities these judgments in other words state opinions about what we ought to do as a society rather than report preferences about what i want as a utility maximizer this essay then argues that contingent valuation can take into account these kinds of judgments which dominate public discourse about the environment only if it moves toward a deliberative discursive jury like research method emphasizing informed discussion leading toward a consensus based on an argument about the public interest

fairness of prices user fee policy and willingness to pay among visitors to a national forest abstract imposing user fees in nature based tourism nbt contexts has been a controversial issue based on the notions of justice and fairness this study extended previous work examining the relationship between attitudes toward user fees and spending support in a proposed structural model of price fairness fee spending support and willingness to pay wtp this paper identified the antecedents of wtp user fees and empirically examined to what extent the data fit the model furthermore the moderating role of place attachment in the model was investigated by using multiple group structural equation modeling subjects n 562 were recreational tourists to a forest area in the southeast u s results revealed that spending support partially played a mediating role in the relationship between perceived price fairness and wtp user fees a multiple group invariance test also demonstrated that while the degree of place identity moderated the effect of price fairness on spending support the degree of place dependence did not influence the relationships among the antecedents of wtp

do existence values for cost benefit analysis exist the use of the contingent valuation method to generate estimates of existence value for input to cost benefit analysis requires that individuals have utility functions defined over the relevant arguments the validity of the assumption that the required utility functions generally exist has been questioned it has been argued that some individuals will respond on the basis of lexicographic preference orderings it has also been argued that some individuals do not consider that market or individual willingness to pay criteria are appropriate where existence value type issues are at stake the paper considers survey evidence bearing upon these arguments it is concluded that the evidence is consistent with the view that it is incorrect to proceed on the assumption that individuals generally satisfy the assumptions required for the existence of existence values for use in cost benefit analysis

interactive vs non interactive knowledge production by faculty members in this article we develop a model of individual choice to study the determinants of faculty members allocation of effort between interactive and noninteractive activities this model is tested by using censored and discrete choice econometric models to estimate optimum effort allocated to interactive activities and real interaction we conclude first that individual responds to nonmonetary rather than monetary incentives and to the difficulty of producing noninteractive rather than interactive knowledge second we detect the possible existence of rationing since optimum effort and real interaction depend on different variables

residential energy efficient technology adoption energy conservation knowledge and attitudes an analysis of european countries abstract relationships between measures of household energy use behavior and household characteristics are estimated using a unique dataset of approximately 5000 households in 10 eu countries and norway family age composition patterns are found to have a distinct impact on household energy use behavior households with young children are more likely to adopt energy efficient technologies and energy conservation practices and place primary importance on energy savings for environmental reasons by contrast households with a high share of elderly members place more importance on financial savings and have lower levels of technology adoption energy conservation practice use and knowledge about household energy use education levels also matter with higher levels associated with energy efficient technology adoption and energy conservation practice use similarly university education increases the stated importance of energy savings for greenhouse gas reductions and decreases the stated importance for financial reasons education impacts also vary greatly across survey countries and there is some evidence of an eastern western european divide with respect to attitudes towards energy savings these cross country differences highlight the need to balance a common eu energy efficiency policy framework with flexibility for country specific policies to address unique constraints to energy efficient technology and conservation practice adoption

are risk regulators rational evidence from hazardous waste cleanup decisions a large literature in economics and social science focuses on how people reason about risks reactions of individuals to risk frequently depart from behavior predicted by full information variants of expected utility theory risk regulators are human and are subject to political pressures that are reflective of people s attitudes toward risk as a result the public policies they espouse may reflect errors in judgment about risk many biases stem from misperceptions of risk individuals overestimate small probabilities overestimate the risks associated with highly publicized dangers and have preferences over the manner not just the magnitude in which risks arise environmental risks associated with hazardous waste sites may be particularly prone to such errors since they involve small risks that are highly publicized indeed the general public ranks hazardous waste sites as the leading environmental risk a growing literature also analyzes how the decisions of risk regulators depart from choices predicted in a standard benefit cost framework as roger g noll and james e krier 1990 point out since regulators are both human and political their decisions may reflect risk biases regulators may exhibit these biases as individuals and because their constituents will express regulatory demands based on risk perceptions risk regulators may take into account the identity of the parties exposed to risk the level of scrutiny by interest groups the nature of congressional representation of affected constituents and the degree of political activity by potentially exposed individuals 3 errors in risk perceptions and risk decisions cause individuals to diverge from expected utility maximization similar errors by policy makers and the influence of risk politics cause regulators to diverge from social welfare maximization this paper examines decisions made by federal and state regulators at hazardous waste sites addressed by the superfund program to determine how their decisions diverge from those predicted by expected utility theory and benefitcost analysis we analyze whether risk perceptions and politics influence two decisions central to the how clean is clean debate at superfund sites the selection of chemical cleanup targets and the expenditure of remediation funds at these contaminated sites we also explore the interactive influence of risk perception factors and political demands previous research on the regulation of chemical risks in standard setting indicates that decisions reflect evidence of risk biases and responsiveness to political factors in assessing the determinants of the epa s decision to cancel pesticide registration maureen l cropper et al 1992 found that the epa was more likely to cancel a pesticide in instances featuring higher risks to the maximally exposed individual user lower benefits associated with continued use of the pesticide higher values of intervention by environmental groups mea viscusi harvard law school harvard university cambridge ma 02138 hamilton sanford institute of public policy duke university durham nc 27708 we have benefited from the comments from two referees and the excellent research assistance of jason bell kristen blann jahn hakes and robert malme research support was provided under cooperative agreement no cr 823604 01 from the u s environmental protection agency office of policy planning and evaluation dr alan carlin and dr suzanne giannini spohn served as contract officers all views and errors expressed are our own l see u s environmental protection agency epa 1987 for a report on this survey evidence 2 this theme is also articulated in richard j zeckhauser and viscusi 1990 noll 1989 provides a more general assessment of the interaction between political concerns and regulatory policy which is a central theme of this paper 3political factors have long played a prominent role in local hazardous waste policies see among others linda cohen 1981 howard kunreuther and douglas easterling 1990 1992 and kunreuther and rajeev gowda 1990

an empirical study of the determinants of green party voting i empirically study the determinants of individuals green voting behavior for this i make use of three datasets from germany a panel dataset and two cross sectional datasets the empirically strongest determinants are the voters attitude or distance to nuclear sites the level of schooling and net income i show that those voters with deviant attitudes or alternative world views are more likely to vote green a result of the fact that the green party has always had the position of a protest party i find little role for demographic variables like gender marital status or the number of children this is in contrast to the stated preference literature age plays a role for explaining voting behavior only insofar as it proxies for health

the public perceptions and willingness to pay from the perspective of the smog crisis in china the deteriorating air quality which is linked to human actions related to energy resources has become an urgent global problem china s air pollution has reached the hazardous level since 2000s in consideration of the serious health and social problems residential demand for clean air is increasing this paper applies the contingent valuation method to estimate public s willingness to pay wtp for reducing air pollution in the urban area of china open ended scenarios through face to face surveys are used to elicit public s wtp the two part model is employed for the estimation the probit model is used to estimate the probability of respondents who have positive wtp values and the interval regression model is employed to estimate the specific wtp level of those with nonzero wtp values the results show that nearly 90 of the respondents are willing to pay for reducing air pollution and the average amount of wtp per individual is 382 6rmb per year household income is found to be positively correlated with people s wtp and those who trust the government are more willing to share the cost of reducing air pollution this study recommends designing some effective mechanisms to tap the potentially available source of money for smog mitigation and improving the transparency of smog governance to enhance the government credibility as solutions to cope with smog crisis

attitudes toward catastrophe in light of climate change and other global threats policy commentators sometimes urge that society should be more concerned about catastrophes this paper reflects on what society s attitude toward low probability high impact events is or should be we first argue that catastrophe risk can be conceived of as a spread in the distribution of losses based on this conception we review studies from decision sciences psychology and behavioral economics that explore people s attitudes toward various social risks contray to popular belief we find more evidence against than in favor of catastrophe aversion the preference for a mean preserving contraction of the loss distribution and discuss a number of possible behavioral explanations next we turn to social choice theory and examine how various social welfare functions handle catastrophe risk we explain why catastrophe aversion may be in conflict with equity concerns and other regarding preferences finally we discuss current approaches to evaluate and regulate catastrophe risk

ex post welfare economics and the theory of merit goods in recent years a number of papers have questioned the extension of the main theorems of welfare economics to a world of uncertainty stemming from the work of arrow 1953 and debreu 1959 the arrow debreu extension is based on the idea that consumer preferences may be defined on state contingent commodities as a special but important case these preferences may be represented by von neumann morgenstern utilities with this interpretation of the commodity space the main theorems of weltare economics remain valid in a world of uncertainty a competitive equilibrium is a pareto optimum a pareto optimum can be sustained as a competitive equilibrium and the diagnosis of the causes of market failure remains as before there are several reasons why one may feel uneasy about this construction a good deal of attention has been paid to the assumption of universality of markets necessary to establish the connection between equilibrium and optimum on a deeper level perhaps are the doubts that one may have about the criterion of welfare or efficiency first should social welfare be a function of individuals expected utilities or should the appropriate concept be that of expected welfare second if probability beliefs are not identical across individuals whose probabilities if any should be used for welfare evaluation in the next section we review some concepts and results in the recent literature on ex post welfare economics and in section ii it is argued that this literature can provide the foundations for a more satisfactory theory of merit goods a concept originally introduced by musgrave 1959 this idea is applied in section iii to a model with a complete set of markets in the arrow debreu sense and in sections iv and v to an incomplete markets model which provides the most natural framework for the study of merit goods various remarks on further aspects of the problem are collected in the concluding section of the paper

the importance of ethics in environmental economics with a focus on existence values the importance of ethics and fundamental value judgments in environmental economics is high lighted by discussing the controversial concept of existence values the social value depends crucially on the social objective which is not necessarily self evident e g since some individuals tend to value nature intrinsically it is shown that the motives behind willingness to pay figures matter for the social value and the conventional view that people respond to cv questions solely in order to maximize their own utility or well being is questioned the importance of being explicit about value judgments is emphasized and it is argued that environmental economics should consider non conventional assumptions which take the social context into account to a larger degree

ordering effects in contingent valuation surveys this paper focuses on ordering effects in cvm surveys how the expressed value of a particular good valued in a sequence of several goods depends on where in the sequence the good is valued we use data from a norwegian cvm survey focusing on wtp for a 50 reduction in air pollution from car traffic to test for the existence of ordering effects and to apply a test for internal consistency we found considerable and significant ordering effects in our data but were not able to reject the hypothesis of internal consistency based on our survey we argue that ordering effects may be a result of rational choice these effects are problematic if a sequential valuation procedure is applied to a simultaneous problem and or the respondents are given imperfect information about the decision problem
