operating flexibility global manufacturing and the option value of a multinational network the multinational corporation is a network of activities located in different countries the value of this network derives from the opportunity to benefit from uncertainty through the coordination of subsidiaries which are geographically dispersed we model this coordination as the operating flexibility to shift production between two manufacturing plants located in different countries a stochastic dynamic programming model treats explicitly this flexibility as equivalent to owning an option the value of which is dependent upon the real exchange rate the model is extended to analyze hysteresis effects and within country growth options we show that the management of across border coordination has led to changes in the heuristic rules used for performance evaluation and transfer pricing

the market value of reducing cancer risk hedonic housing prices with changing information 1 introduction market evidence on the value of a statistical life invariably consists of cross sectional evidence on risks and prices or wages at a point in time if information about the level of risk changes over time and people incorporate this information in a rational manner there will be a corresponding price response on the basis of these temporal changes one can estimate the market price risk tradeoff eliminating many confounding time invariant effects that cannot be controlled for using cross sectional data this paper examines the market response to the release of government information about the level of risk at hazardous waste sites and provides insight into the rationality of this response studies based on experimental evidence and survey data often find that individual beliefs may deviate from objective risk levels 1 people often overestimate highly publicized risks and mortality risks in the case of hazardous waste risks bias in risk beliefs often leads to considerable public reaction and pressure for site cleanups which may be an inefficient outcome by using market data one can examine whether this intense public reaction carries over to contexts in which private money is at stake government agencies frequently use information provision as a regulatory device particularly since the advent of the right to know movement of the 1980s examples of information provision efforts include the food and drug administration s requirement that many prescription drugs indude information inserts the department of housing and urban development s requirement that sellers of houses built before 1950 inform buyers about the presence of lead based paints and the environmental protection agency s epa requirement that manufacturing facilities report their annual releases of chemicals above a threshold amount for a list of over 600 substances such regulations imply a belief that citizens can learn from information about risk and rationally adjust their prior beliefs towards the objective risk level in light of the information this article provides market evidence to bolster the results of some survey studies of information transfer that suggest that individuals revise their risk beliefs in response to new information 2 the u s federal policy dealing with hazardous waste sites is known as the superfund program the most hazardous sites are targeted for cleanup and placed on a government priority roster called the national priorities list npl extension of the classic theory of compensating differentials to the housing market implies that environmental disamenities such as hazardous waste sites will reduce housing prices rosen 1974 the negative impact of hazardous waste sites on the housing prices of nearby residences is well documented for example in a previous study gayer hamilton and viscusi 2000 we used an analysis that focused on the sale of 16 928 houses from 1988 to 1993 that surround superfund sites in greater grand rapids michigan we found that before the epa released its risk report a reduction in the cancer risk from neighborhood superfund sites by the mean level of risk would increase the average value of a house by 238 in 1996 dollars 3 to estimate this willingness of residents to pay to avoid cancer risks before the release of the epa s risk report we assumed that residents prior beliefs were equal to the objectively measured risks suggested by the report thus this analysis was based on the very strong informational assumption that residents could in effect predict the results of the epa s site specific risk assessments before the release of the report the price risk tradeoff implied a value of a statistical cancer case of 51 million once the epa released its risk information the implied value of a statistical cancer case was 4 million these results suggest that after the release of the epa s risk report revealed preferences for avoiding superfund risks were consistent with surveys of the value of a statistical life in the labor market

nonrenewable resource scarcity nonrenewable resource theory often is summarized by hotelling s rule this paper reviews theoretical extensions and empirical investigations of resource extraction models observed data are often inconsistent with the hotelling rule suggesting that other characteristics of nonrenewable resource supply including exploration heterogeneous ore quality technological progress and capital investment are important determinants of the dynamic behavior of resource prices given the persistent recurrence of concern about nonrenewable resource scarcity measures of nonrenewable resource scarcity and the empirical evidence for the time trends of those measures are reviewed finally the implications of nonrenewable resource scarcity for economic growth are examined

a review of wta wtp studies abstract willingness to accept wta is usually substantially higher than willingness to pay wtp these constructs have been studied for roughly 30 years and with a wide variety of goods this paper reviews those studies we find that the less the good is like an ordinary market good the higher is the ratio the ratio is highest for non market goods next highest for ordinary private goods and lowest for experiments involving forms of money a generalization of this pattern holds even when we account for differences in survey design ordinary goods have lower ratios than non ordinary ones we also find that ratios in real experiments are not significantly different from hypothetical experiments and that incentive compatible elicitation yields higher ratios

global plant capacity and product allocation with pricing decisions trade offs in global manufacturing decisions involve markets resource costs trade barriers currency exchange rates joint ventures and investments we develop a model that optimizes plant investment decisions while ensuring that the plant investment overhead is optimally absorbed by products produced from that plant the model also simultaneously determines prices by products and countries the special structure of the model is exploited to construct a fast solution procedure the model is used to study the implications of labor cost transportation cost demand and import tariff on production quantities investment and overhead absorption pattern implications of changes in other global parameters such as local content rule local taxes size of the market in a country and long term exchange rates are also studied

asymmetries in ordered strength of preference models implications of focus shift for discrete choice preference estimation this paper explores potential focus shift asymmetries in an ordered strength of preference model applied to contingent choice data a focus shift occurs when respondents weight factors differently when assessing preference for an accepted scenario than they do when assessing preference for a rejected scenario and may imply that respondents do not refer to a single underlying preference function using data drawn from a survey which addressed preferences for watershed management the model results identified focus shift asymmetries in the ordered strength of preference model the paper discusses implications for policy survey design and discrete choice preference estimation

carcinogen regulation risk characteristics and the synthetic risk bias why does the government regulate different kinds of risks economists usually trace the motivation for the regulation to the existence of some form of market failure in such instances it will be desirable to regulate substances for which the benefits of the regulation exceed the costs which will potentially be the case if there is some inadequacy in the market the restrictive legislative mandates of regulatory agencies in some cases prohibit basing regulations on a balancing of benefits and costs and at the very least seldom encourage such balancing 1 as a result one would expect the benefits of regulatory efforts to play a greater role in regulatory decisions than do the costs 2 this pattern is exemplified by the high implicit values per statistical life that have been observed for u s regulatory efforts 3 regulatory agencies consequently tend to be risk oriented in their policy approach what this characterization neglects is that even within the context of emphasizing risks regulatory agencies may not be making balanced decisions the risk level consists of two principal components the probability of an adverse outcome and the number of people affected the probability depends on the potency of the exposure the frequency of the exposure and similar kinds of parameters regulatory agencies are generally concerned with the risk particularly with respect to the potency of the chemicals in contrast the number of people exposed to the risk plays a much less prominent role in regulatory decisions the standard regulatory policy trigger is typically linked to a probability of an adverse outcome as opposed to an expected body count the u s environmental protection agency superfund program is a case in point in that effort the focus is on the risks posed by different pathways by which populations could be exposed to the hazard in the course of the detailed policy analysis prepared for each superfund site epa never assesses the size of the population exposed to the risk moreover there is not even an assessment of the probability that a future population will be exposed to the risk the presence of a risk with a potential exposure to a future population is sufficient to trigger government action extrapolation from this experience to other instances would lead one to expect that the probability of cancer or some other adverse health outcome would be the driving force behind regulatory decisions however even this characterization may be overly broad in this paper i will explore the decision to regulate natural and synthetic chemicals to what extent are regulatory decisions driven by the severity of the risk as opposed to the character of the risk exposure the striking result is that the risk severity dlavs a very small role instead tdiscussants maureen cropper world bank don kenkel pennsylvania state university tyler cowen george mason university

rates of time preference and valuations of the duration of life abstract this paper develops a multi period markov model of the lifetime choice of occupational fatality risks the empirical model analyzes the wage effects of job risks using the 1982 university of michigan panel study of income dynamics in conjunction with death statistics from the u s national traumatic occupational fatality survey evidence regarding workers intertemporal choices with respect to risks with long term implications is broadly consistent with rational behavior workers implicit real rate of time preference with respect to future life years equals approximately 11 percent this rate of time preference decreases with education

a microeconometric test of the theory of exhaustible resources abstract this paper generalizes extant developments of the economic theory of exhaustible resource production derives and extends a halvorsen and smith 1991 quarterly journal of economics 106 123 140 type test of the theory and applies the test to a sample of natural gas resources to facilitate our empirical test we extend the model developed in chermak and patrick 1995 journal of environmental economics and management 28 174 189 to explicitly account for the fact that the extracted resource gross product must be processed to obtain the final saleable product duality theory is used to derive econometric models with which the theory is statistically tested using panel data from 29 natural gas wells shadow prices of the resource stock through time which are generally unobservable but necessary for the test are estimated via the indirect cost function contrary to the extant literature we find inter alia that i at any point in time ceteris paribus the in situ resource price a decreases with gross production and b increases with final production and ii we cannot reject the theory of exhaustible resources i e producer behavior is consistent with the theory

the elephant in hotelling s room this paper questions the assumption commonly used in theoretical and policy research that scarcity rents make up a large proportion of market prices for oil and coal we show that the empirical literature simple calculations of historical and future scarcity rent shares and possible theoretical explanations all imply the same overall conclusions that scarcity rents seem to have been marginal or non existent historically that they almost certainly do not dominate fossil resource prices today and that there will be other factors shaping the prices in the upcoming decades we therefore argue that using the scarcity rent as the main or only basis for policy or for explaining empirical outcomes is ill advised

existence of equilibria in exhaustible resource industries nonconvexities and discrete vs continuous time abstract i demonstrate in a very general model that decreasing or u shaped average cost curves always rule out competitive equilibrium in continuous time models of extractive industries discrete time models of these industries however can have competitive equilibria existence of competitive equilibria in the presence of nonconvexities is sometimes more and sometimes less problematic for extractive industries than for industries making a producible commodity

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

a test of the theory of reference dependent preferences eight alternative methods of eliciting preferences between money and a consumption good are identified two of these are standard willingness to accept and willingness to pay measures these methods differ with respect to the reference point used and the dimension in which responses are expressed the loss aversion hypothesis of tversky and kahneman s theory of reference dependent preferences predicts systematic differences between the preferences elicited by these methods these predictions are tested by eliciting individuals preferences for two private consumption goods the experimental design is incentive compatible and controls for income and substitution effects the theory s predictions are broadly confirmed

risk self protection and ex ante economic value abstract we develop three propositions about the ex ante value of reduced risk if there is a continuous outcome distribution and if self protection influences outcome probability and severity then 1 unobservable utility terms cannot be eliminated from the ex ante value expressions 2 knowledge of the convexity or the nonconvexity of dose response functions is insufficient to sign changes in these expressions and 3 self protection expenditures need not be a lower bound measure of these expressions therefore many restrictions applied in recent empirical work on the economic value of risk changes are not immediately transferable to settings where endogenous risks prevail

subjective versus technical risk estimates do risk communication policies increase consistency abstract this paper reports the first comparison of subjective and technical risk estimates for a real source of risk exposure to radon the analysis also considers the effects of the information framing for this comparison of risk estimates the results suggest that the framing of the risk explanations does affect how individuals adjusted their subjective risk perceptions in response to differences in the amount and duration of their radon exposures thus our findings support the need to describe the role of cognitive factors involved in processing risk information within economic models of the formation of risk perceptions

proportionality of willingness to pay to small changes in risk the impact of attitudinal factors in scope tests sensitivity proportionality of willingness to pay wtp to small risk changes is often used as a criterion to test for valid measures of economic preferences in a contingent valuation cv study conducted in austria 1 005 respondents were asked their wtp for preventing an increase in the risk of being killed in an avalanche of 1 42 500 and 3 42 500 respectively wtp for the higher variation in risk is significantly greater than wtp for the lower risk change we find evidence that those respondents who have had personal experience of avalanches in recent years combine the information about future risk increase as provided in the survey with the observed number of fatal avalanche accidents in the past proportionality of wtp holds if such prior experience is taken into account and if attitudinal factors in scope tests are controlled for

household energy use applying behavioural economics to understand consumer decision making and behaviour household energy conservation has emerged as a major challenge and opportunity for researchers practitioners and policymakers consumers also seem to be gaining greater awareness of the value and need for sustainable energy practices particularly amid growing public concerns over greenhouse gas emissions and climate change yet even with adequate knowledge of how to save energy and a professed desire to do so many consumers still fail to take noticeable steps towards energy efficiency and conservation there is often a sizeable discrepancy between peoples self reported knowledge values attitudes and intentions and their observable behaviour examples include the well known knowledge action gap and value action gap but neither is household energy consumption driven primarily by financial incentives and the rational pursuit of material interests in fact people sometimes respond in unexpected and undesirable ways to rewards and sanctions intended to shift consumers cost benefit calculus in favour of sustainable behaviours why is this so why is household energy consumption and conservation difficult to predict from either core values or material interests by drawing on critical insights from behavioural economics and psychology we illuminate the key cognitive biases and motivational factors that may explain why energy related behaviour so often fails to align with either the personal values or material interests of consumers understanding these psychological phenomena can make household and community responses to public policy interventions less surprising and in parallel can help us design more cost effective and mass scalable behavioural solutions to encourage renewable and sustainable energy use among consumers

understanding household energy use decision making and behaviour in guinea conakry by applying behavioural economics abstract for decades generalized frauds have left the electrical sector of guinea with an entirely defective financial scheme as a developing nation guinea s electricity consumption has been relatively low for a long time although it has been increasing recently due to increasing power generation the growth in power capacity is due to the construction of two new dams kaleta dam 240 mw which is already operational and souapiti dam 550 mw which is still under construction taking into account that the country has so far been without electricity there is a need to assess and predict consumer behaviour before the full completion of these projects the aim of this study is to make the household and community reactions to public policy interventions less surprising however even sufficient knowledge of how to conserve energy and a stated desire to do so many consumers still fail to take perceptible measures to increase energy efficiency and conservation why is this so by focusing on crucial insights from behavioural economics and psychology we highlight the incentive factors the basic cognitive biases and the psychological phenomena that cause this disconnect understanding these factors can help us to design sustainable energy use among consumers in guinea conakry

misperceived job hazards and welfare abstract bayesian workers produce chemicals hazardously in one sector of a two sector economy having one safe sector adopting an expected ex post welfare perspective we show workers misperceptions of hazards entail a classic externality we characterise chemicals competitive monopoly and socially efficient outputs assuming workers receive identical wage accident compensation contracts under each the value of information which induces workers to place greater stress on firms safety records or sharpens their priors and extend the standard monopoly welfare loss index for sufficient conditions for monopoly to be preferred to competition in chemicals and for size ranking monopoly and efficient chemical outputs

an equilibrium analysis of defensive response to entry using a coupled response function model we determine the optimal response to competitive entry in a market characterized by a market share attraction model the response of an incumbent is limited to changes in prices advertising and distribution expenditures brand positions are assumed to be fixed we also assume that the entrant s position is chosen exogenously and that the sales potential of the market is constant after proving the existence of a unique nash equilibrium we show that the optimal response depends on the relative market share of the incumbents the response by nondominant brands with market shares less than 50 mirrors the prediction by decoupled response function models reduce price advertising and distribution spending for the dominant brand having a market share of 50 the response is to reduce price and increase marketing spending this finding explains previous empirical results that could not be addressed by the decoupled models

risk perception in psychology and economics abstract the concept of rationality has been basic to most economic analysis its content has been successively refined over the generations as applied to the static world of certainty it has turned out to be a weak hypothesis not easily refuted and therefore not very useful as an explanation though not literally a tautology but recent decades have seen the development of stronger versions applied to a world in which time and uncertainty are real among its most important manifestations have been criteria for consistency in allocation over time the expected utility hypothesis of behavior under uncertainty and what may be termed the bayesian hypothesis for learning that is the consistent use of conditional probabilities for changing beliefs on the basis of new information these hypotheses have been used widely in offering explanations of empirically observed behavior though as not infrequently in economics the theoretical development has gone much further than the empirical implementation these hypotheses have also been used increasingly in normative analysis as a component of benefit cost studies therefore frequently referred to as benefit risk studies the value of reducing mortality rates from diseases for example has been studied by assuming that choice of occupations is made inter alia by comparing wage differences with mortality differences

risk risk versus standard gamble procedures for measuring health state utilities contingent valuation cv has been widely used to measure the potential benefits derived from different policy decisions however doubt now exists about the validity of the cv method and alternative approaches to benefit valuation have been proposed the paper reports on the results of a study which was designed to test the viability of two of the most prominent of the alternatives the risk risk rr and standard gamble sg approaches if individual preferences are consistent with the axioms of von neumann morgenstern expected utility theory eut then the two methods should generate the same interval scales for any given set of health states however the results show that sg utilities are substantially higher than rr ones thus casting doubt on these axioms the paper discusses alternatives to eut which might better expalin the discrepancies found it also considers whether the results might be explained in terms of status quo bias and or by the relative difficulty of rr questions the results presen

an investigation of the rationality of consumer valuations of multiple health risks after developing a conceptual analysis of consumer valuation of multiple risks we explore both economic and cognitive hypotheses regarding individual risk taking using a sample of over 1 500 consumers our study ascertains risk dollar tradeoffs for the risks associated with using an insecticide and a toilet bowl cleaner we observe the expected positive valuation of risk reductions and find empirical support for a diminishing in the valuation of risk reduction as the extent of the risk reduction increases we also find evidence of certainty premiums for the total elimination of one risk but no strong evidence of additional certainty premiums for the elimination of multiple risks strong reference risk effects are evident as increases in risk were valued much more greatly than were decreases

parental behavior and the value of children s health a health production approach data on individual children and on sibling pairs are used to examine how family resource allocations affect children s health and to estimate willingness to pay for reduced acute illness in children results highlight the importance of accounting for the endogeneity of child health and suggest that children with greater stocks of health capital whose parents invest in preventive and remedial medical care experience fewer days of illness estimated willingness to pay to avoid one day of illness induced school loss is about 100 to 150 a range broadly consistent with limited prior evidence but sub stantially more than unit values applied in recent policy analyses all else equal willingness to pay is higher among single parents and for uninsured children and the estimated income elasticity is only 0 14 implied aggregate benefits of reductions in children s sick time associated with air pollution control may be substantial

comorbidities and the willingness to pay for health improvements we show that the willingness to pay for health improvements increases with the severity and probability of occurrence of comorbidities this result which is obtained under mild restrictions on the shape of the utility function has important implications for cost benefit studies applied to health care in particular it implies that the discrimination of the elderly believed to be implicit in cost benefit analysis is less of a problem than commonly thought

a test of the theory of exhaustible resources an empirical test of the theory of exhaustible resources requires an estimate of the time path of the shadow price of the unextracted resource that generally is not observable because of the prevalence of vertical integration in natural resource industries in this paper we use duality theory to derive an econometric model that provides a statistical test of the theory of exhaustible resources a restricted cost function is used to obtain estimates of the shadow prices of unextracted resources the procedure is illustrated with data for the canadian metal mining industry for this industry the empirical implications of the theory of exhaustible resources are strongly rejected

futures markets price stabilization and efficient exploitation of exhaustible resources markets for natural resource futures contracts and cash forward contracts experience a rapid growth according to theory this should result in more efficient resource depletion implying that price formation is more consistent with hotelling s rule the rationale of this stabilization effect is briefly discussed next we analyze the impact of expanding futures markets on the behaviour of individual resource owners trading on the cash market using a simple pulse extraction model we demonstrate that the expected time of depletion can shift to the present or the future and that utility of exploitation can go up or down as market prices are stabilized

price expectations ore quality selection and the supply of a nonrenewable resource abstract economic models of depletion imply that the present value price of a resource and the quality of extracted ore should be directly related the empirical evidence is that in the short run the average quality of extracted ore and in some cases metal output decline in response to a price increase this paper examines a model of extraction with heterogeneous ore quality within a deposit and revised price expectations in which this seemingly paradoxical supply response is rationalized as the outcome of ore quality selection which maximizes the present value of the mine

untested hypotheses in non renewable resource economics the present paper reviews the literature on the empirical implications of the hotelling rule and suggests directions for further research in this area

existence and transversality conditions for a general unbounded horizon model of the mining firm abstract this paper derives conditions under which optimal programs exist for a general model of the competitive or monopolistic mining firm the model significantly extends and synthesizes previous formulations by including both resource extraction and discoveries of new reserves with stock dependent resource exploitation costs and incomplete resource exhaustion endogenous technical innovation and state dependent resource demand in addition the analysis addresses complications arising from having optimal programs defined over an unbounded horizon with the possibility of either a finite or infinite terminal time and a non zero terminal salvage valuation if the terminal time is finite the necessity of the infinite horizon transversality conditions also is established the paper illustrates a strongly intuitive approach to existence questions for infinite horizon or unbounded horizon control problems with weaker concavity and interiority assumptions than are often encountered in the literature

income effects and the value of health although valuations of risk should increase with income hedonic wage studies have not been well suited to assessing this relationship using survey data on consumer valuations of product safety this paper analyzes the role of income effects for several utility functions the methodology developed in this paper assesses the effect of income on the certainty equivalent value of the health effect income elasticities range from 0 18 to 0 39 and on the risk money tradeoff for small changes in risk income elasticities range from 0 17 to 0 38 health status is a normal economic good

measurement of consumer patient preferences using a hybrid contingent valuation method this study introduces a hybrid two stage contingent valuation method applied to asthma treatment respondents are initially offered a choice between hypothetical medications implying a tradeoff between safety and efficacy stage two elicits willingness to pay wtp for an improvement along a single risk dimension estimates of the value of asthma control based on the initial risk tradeoff stage range from approximately us 1400 to us 2100 per year assuming a us 6 million value of life analysis of the second stage wtp responses yield estimates for the value of a statistical life of approximately us 9 million and for asthma control of approximately us 2200 per year

economic indicators of resource scarcity comment abstract a recent article in this journal by richard norgaard j environ econom management 19 19 25 1990 concludes that the literature on economic indicators of resource scarcity is not a scientific endeavor we argue the contrary by surveying two research literatures omitted by norgaard but inspired by the resource indicators literature and by investigating norgaard s claim to have found a logical flaw we conclude that the research on economic indicators of resource scarcity is a scientific endeavor and that it is a distinguishing feature of the sub discipline of environmental and resource economics

the economics of risks to life this study asks two questions 1 what is the net value to the representative individual over his life time of activities that alter age specific mortality risks 2 what is the cost to the representative individual of activities that take a life at random at a given age results derived from an economic demographic model with full age specific accounting have a strong actuarial flavor alterations in the mortality schedule caused say by a medical breakthrough should be assessed on the utility of expected additional life years production and reproduction less expected social costs of support loss of life at a specific age due to an accident say should be assessed on the opportunity costs of expected lost years of living lost production and reproduction less expected social support costs the results show that current methods in general leave out an important social transfer term that value of a life lost is highly age dependent and that the degree of diminishing returns to consumption is crucial in calculations of the economic cost of risks

pricing the limits to growth from minerals depletion this paper evaluates the loss of global welfare from exhaustion of nonrenewable resources such as oil the underlying methodology represents an empirical application of some recent developments in the theory of green accounting and sustainability the paper estimates that the world loses the equivalent of about 1 percent of final consumption per year from finiteness of the earth s resources compared with a counterfactual trajectory where global extraction of minerals is allowed to remain forever constant at today s flow rates and extraction costs

an integrated location production distribution and investment model for a multinational corporation abstract we present a mixed integer linear formulation that extends published models on multinational corporation facility location decisions by including exogenous variables such as exchange rates and tariff rates and incorporating production distribution and investment decisions the model provides insights on production levels facility configurations distribution strategies and levels of investment needed at these facilities and explores factors that influence the facility s configuration decisions several scenarios are considered based on various facility configurations and levels of exchange and tariff rates the results obtained from these show that the model s performance and results are in complete agreement with accepted economic theories

on monopoly power in extractive resource markets abstract potential monopoly power in extractive resource markets is reduced by the depletability of reserves this paper examines the dependence of monopoly power on resource rent and on uncertainty over future reserve levels a model is developed that treats reserves as inventories that fluctuate stochastically over time as a result of exploration development and production activities solutions of the model illustrate how output and monopoly power vary with the elasticity of demand rent as a fraction of price and the variance of reserve fluctuations it is shown that uncertainty over future reserves can speed up production and by reducing resource rent restore part of the monopoly power otherwise lost because of depletion antitrust implications are discussed with reference to several resources

alarmist decisions with divergent risk information receipt of multiple sources of risk information ideally should foster sounder decisions under uncertainty this paper s original survey results for environmental risks suggest that the learning process is reasonable in many respects bur it does not accord with a rational bayesian learning model divergent risk assessments from different sources produce extreme violations of rationality as there is inordinate weight on the high risk assessment this alarmist reaction holds for both government and industry information sources this phenomenon may account for the commonly observed phenomenon of public overreaction to highly publicised risks

parental altruism and the value of avoiding acute illness are kids worth more than parents abstract a model describing parents preferences to relieve their own and their children s acute illnesses is estimated using stated preference data estimated marginal rates of substitution mrs between child and parent illness are about two indicating that parents value children s illness attributes twice as highly as their own the mrs is larger for younger children falls toward unity as the child approaches adulthood and appears to reflect parental altruism rather than parent child differences in initial health or illness costs intra family allocations may compensate for chronic health impairments parents willingness to pay to avoid own or child illness increases with income declines with fertility increases at a decreasing rate with duration and number of symptoms and depends on perceived discomfort and activity restrictions current methods of assessing morbidity benefits of environmental regulations may understate substantially the value of children s health particularly in african american families

predicting buyer seller pricing disparities numerous studies have shown that compensation demanded cd to give up a commodity often greatly exceeds willingness to pay wtp to obtain the same commodity even in incentive compatible experiments that penalize strategic misrepresentation observed cd wtp disparities are too large to be reconciled with traditional assumptions of economic rationality a prospect theory based behavioral framework for predicting cd and wtp is proposed which produces five distinct transaction encoding rules any one of which can in principle apply to a buyer or a seller according to this framework cd wtp gaps occur when buyers and sellers encode the prospective transaction differently and gaps can occur in multiple ways and vary in size depending on encoding the transaction encoding framework was tested in two experiments in experiment 1 model fits to subjects cd and wtp for lottery tickets were consistent with the hypothesis that buyers and sellers encode transaction problems differently moreover the quite large observed cd wtp gaps were explained fully by encoding when differences between buyers and sellers encoding processes were taken into account their estimated utility value and probability weighting functions did not differ the present framework and results show that the widely cited endowment effect is but one of several ways in which loss aversion can give rise to cd wtp gaps consistent with this broadened perspective experiment 2 demonstrated cd wtp gaps in the absence of an endowment effect and in the absence of rational economic causes the transaction encoding framework 1 provides a structured approach for predicting and testing the effects of a variety of task factors on pricing behavior and transaction outcomes and 2 reveals the useful property that in many cases the ratio cd wtp can be interpreted as a direct measure of the degree of loss aversion

the wto the environment and health and safety standards the world trade organization wto is a product of the general agreement on tariffs and trade gatt the wto was created in the last round of negotiations uruguay round 1986 94 to provide a stronger set of institutions to administer the various agreements negotiated under the gatt framework because the wto is more powerful than its predecessors critics claim that it poses a threat to national sovereignty concerns about the ability of nations to set their own environmental and health and safety agendas have figured prominently in these critiques in addition critics suggest that the wto prioritises trade objectives at the expense of environmental and health and safety objectives the article explores the extent to which the wto has been able to reconcile trade environmental and health and safety objectives by analysing its rulings on these matters overall this analysis suggests that the wto dispute resolution process has balanced all three sets of objectives however it is important to note the small number of disputes to date only 21of the 175 disputes before the wto involve environmental and health and safety matters further the wto has issued decisions in only six of these cases

formation of risk beliefs joint production and willingness to pay to avoid skin cancer this paper uses a survey of risk beliefs about skin cancer to provide new evidence on how people view risky situations empirical results presented are based on a measure of risk beliefs held at the time of the survey key findings are that risk beliefs about skin cancer account for factors including skin type complexion and sunlight exposure history also the connection between risk beliefs and willingness to pay is explored by using reservation prices for a sun protection product a new method for treating joint production in a household production framework is developed to support this analysis copyright 1996 by mit press

measurement of the in situ value of exhaustible resources an input distance function abstract we develop a methodology to derive the shadow in situ price of nickel by utilizing an input distance function which can improve upon previous estimates our estimates hold regardless of market power and actual cost minimization the time path of the shadow in situ price is obtained using annual data for inco a nickel company empirical results suggest a slightly increasing in situ price of nickel over the period 1947 92 but the dynamic optimality condition does not hold comparison with the time path of the in situ price obtained by estimating a cost function indicates a sizable discrepancy between the two time trajectories

utility based measures of health mates the scope of this debate is inherently limited market estimates can provide information only on the average rate of trade off of income for risks these trade offs are also pertinent only to marginal changes in risk important policy questions such as the benefits of nonmarginal changes in risks or the benefits of risk reductions in heterogenous populations cannot be adequately explored with results from market settings the increased availability of survey data has brought these and many other questions regarding individual valuation of health risks within the range of answerable inquiries in a standard survey setting consumers are faced with a series of hypothetical choices for which subjects give a probability or an income value that makes them indifferent between the lotteries an es

formal choice models in marketing the paper gives an overview and evaluates the theoretical traditions underlying choice models that are used in marketing in particular the emphasis of this essay is on the underlying assumptions limitations and empirical demands of these choice models four fundamental choice models are used as a basis to analyze this complex field the neoclassical economic theory as extended by lancaster the risk preference theory of choices under uncertainty the strict utility theory and the random utility theory these four choice models and their extensions are compared and contrasted along the three critical steps in the model building process theory generation parameterization and estimation

estimation of market power in a nonrenewable resource industry in nonrenewable resource industries the existence of a markup of price over marginal market cost may reflect the existence of an implicit user cost for the resource rather than market power we show that valid estimates of market power can be obtained by the joint estimation of a restricted cost function and an inverse supply relation estimation of the model with data for the largest firm in the international nickel industry indicates that output price substantially exceeded marginal market cost with most of the difference due to the exercise of market power rather than the user cost of the resource

altruism fertility and the value of children health policy evaluation and intergenerational welfare abstract this paper accounts for the value of children and future generations in the evaluation of health policies this is achieved through the incorporation of altruism and fertility in a value of life type of framework we are able to express adults willingness to pay for changes in child mortality and also to incorporate the welfare of future generations in the evaluation of current policies our model clarifies a series of puzzles from the literature on the value of life and on intergenerational welfare comparisons we show that by incorporating altruism and fertility into the analysis of the recent u s experience the estimated welfare gain of a young adult from reductions in mortality easily doubles

estimation of state dependent utility functions using survey data surveys of individual s risk dollar trade offs illuminate not only the local trade off rates but also can be used to address more fundamental questions about the structure of utility functions this largely unexplored empirical area is investigated by developing an econometric technique to estimate utility functions based on survey data on risk dollar trade offs for minor health effects the empirical tests indicate that for all but one of the temporary health effects considered consumers treat injuries as tantamount to a drop in income implying that the health impact does not alter the structure of the utility function in a fundamental way copyright 1991 by mit press

valuing the incremental benefits of groundwater protection when exposure levels are known both economic theory and psychological research indicate that benefit functions for reductions in health risk exposures may be conditional on current exposures using nitrates found in household wells it is demonstrated that perceptions of health risks across exposure levels are affected by the individual s current exposure level thus providing support for a conditional benefits function approach functions of conditional incremental benefits are estimated from a contingent valuation study of households that had been informed of their water test results incremental benefits reach a peak at an intermediate level of nitrates and then decline possible explanations for this non convexity are provided

a test of the hotelling rule using old growth timber data the paper tests hotelling s prediction that scarcity rent for a non renewable resource will rise at the rate of discount in a market equilibrium we perform the test using data for old growth timber a resource that is effectively non renewable in contrast to previous studies for this resource a measure of scarcity rent is directly observable in the form of stumpage price bids in timber auctions we construct a model that allows for replanting and captures the institutional framework of the western u s timber market the modified hotelling rule that we derive is not rejected in several of our specifications

adjustment costs and pricing to market theory and evidence abstract this paper develops an adjustment cost model of pricing to market the model consists of a monopolist who supplies an identical nondurable good to two foreign markets it is shown that the degree of pricing to market increases with the relative importance of the transitory component in exchange rates customs data from 1978 through 1987 on u s and canadian imports of seven german commodities are used to estimate the model s parameters and test its over identifying restrictions

mineral depletion with cost as the extraction limit a model applied to the behavior of prices in the nickel industry abstract this article follows papers by pindyck and heal and barrow in applying a hotelling type depletion model to a particular resource industry in this case that of nickel by means of the model the resource rent per ton of nickel is calculated as the proper index of extractive resource scarcity the time path of this resource rent indicates that the model explains industry behavior well and that as in the two previous studies depletion has been an important determinant of prices and rents in this industry

survival versus consumption we develop an indirect method to estimate utility and willingness to pay wtp for reductions in the risk of death at various ages using a life cycle model of consumption we assume that an individual sets his consumption level each year so as to maximize his expected lifetime utility alternative assumptions about opportunities for borrowing and annuities characterize two polar types of societies in our robinson crusoe case an individual must be entirely self sufficient and annuities are not available in our perfect markets case an individual can borrow against future earnings and purchase actuarially fair annuities we show that under these assumptions wtp is the sum of livelihood discounted expected future earnings and consumer surplus to illustrate our methods we derive wtp for an average financially independent american man under plausible assumptions the model is calibrated to 1978 earnings e g 18 000 per year for men aged 45 54 with at least some income in the robinson crusoe case wtp increases from 500 000 at age 20 to a peak of 1 250 000 at age 40 and declines to 630 000 at age 60 in the perfect markets case age variations are less pronounced wtp is 1 050 000 at age 20 peaks at 1 070 000 at age 25 and declines to 600 000 at age 60 these results suggest that individuals value risks to their lives at several times the pro rata share of their future earnings

choice under uncertainty problems solved and unsolved ffifteen years ago the theory of choice under uncertainty could be considered one of the success stories of economic analysis it rested on solid axiomatic foundations it had seen important breakthroughs in the analytics of risk risk aversion and their applications to economic issues and it stood ready to provide the theoretical underpinnings for the newly emerging information revolution in economics 1 today choice under uncertainty is a field in flux the standard theory is being challenged on several grounds from both within and outside economics the nature of these challenges and of our profession s responses to them is the topic of this paper

an application of depletion theory to a base metal canadian nickel advances in economic theory in the past decade have considerably increased our understanding of the implications of the depletability of important natural resources this paper an application of that theory seeks to estimate the depletion charge which should be imputed to canadian nickel by first estimating the quality characteristics of remaining reserves rather strong assumptions are required to derive a charge in excess of five per cent of the metal s value and it is concluded that the imputation of a significant user cost to canadian metal production would not be socially optimal une application de la theorie de lepuisement a un metal de base le nickel au canada certains travaux de theorie economique ont consid6rablement accrfu notre comprehension des consequences de l 6puisement de certaines ressources naturelles importantes ce memoire est une application des resultats de ces travaux il veut 6valuer le cofut d epuisement le cofut qu on devrait imputer a la d6gradation du stock de nickel canadien en 6valuant la qualite des reserves de nickel qui restent il appert que l on doit faire des hypotheses assez extremes pour deriver un cofut impute de plus de cinq pourcents de la valeur du metal comme cofut de la d6gradation des stocks donc on peut conclure que l imputation d un cofut d 6puisement important sur la production canadienne ne serait pas socialement optimal

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

profit variability in for profit and not for profit hospitals this paper proposes two tests of the hypothesis that not for profit hospitals nfps behave differently than for profit hospitals the profit variability test states that the profits of an nfp will be less variable over time than profits of a for profit hospital if the nfp maximizes utility subject to a profit constraint the second test examines whether nfp profits respond less to change in exogenous factors such as medicare reimbursement rates than profits of for profit hospitals both tests performed on panel data from 1983 to 1988 support the hypothesis that nfps behave differently than for profit hospitals

product positioning under price competition this paper presents a consumer based methodology for new product pricing and positioning in the face of price competition the price competition is modelled as a nash equilibrium for which two complementary approaches are employed an analytical approach of duopoly provides qualitative insights into the competitive behavior and a numerical approach of general oligopoly provides quantitative solutions under a wide variety of market scenarios the optimal product positioning is formulated as a stackelberg nash leader followers equilibrium which can be solved numerically using recent advances in the field of variational inequalities a small example concerning analgesics is used to illustrate this methodology

depletion effects and nonrenewable resource supply a diagrammatic exposition to address important research and policy questions related to nonrenewable resources such as the impacts of federal tax changes on the u s extractive sector the current ill health of the u s minerals industry the impacts of environmental initiatives on coal production and use and management of outer continental shelf resources a solid conceptual description of the supply process for nonrenewable resources is needed de

are individuals bayesian decision makers there has been increasing interest in whether normative models of individual choice under uncertainty accord with actual behavior these concerns have been much greater than in other economic contexts because of the particularly severe demands such decisions place on the rationality of the decision maker the limitations of these decisions have widespread consequences as they provide the rationale for many governmental efforts to regulate the risks people face here i explore the issues raised by a bayesian decision framework focusing particularly on my analyses of worker and consumer behavior

information and exhaustible resources a bayesian analysis abstract we develop a continuous time bayesian model of investment in information about an exhaustible resource because of the way that information affects expectations the deterministic hotelling rule turns out to be more appropriate as a description of how resource owners forecast the value of their stocks than as a predictor of observed changes in the resource price a flow of information generates both unanticipated changes in expectations which cause the mean rate of change in the resource price to deviate systematically from the deterministic hotelling rule and reductions in uncertainty which do not affect the hotelling prediction

hotelling under pressure we show that oil production from existing wells in texas does not respond to oil prices while drilling activity and costs respond strongly to explain these facts we reformulate hotelling s class

valuing operational flexibility under exchange rate risk in this paper we develop a stochastic dynamic programming formulation for the valuation of global manufacturing strategy options with switching costs overall we adopt a hierarchical approach first exchange rates are modeled as stochastic diffusion processes that exhibit intercountry correlation second the firm s global manufacturing strategy determines options for alternative product designs as well as supply chain network designs product options introduce international supply flexibility supply chain network options determine the firm s manufacturing flexibility through production capacity and supply chain network linkages third switching costs determine the cost of operational hedging i e the costs associated with reducing downside risks overall the firm maximizes its expected discounted global after tax value through the exercise of product and supply chain network options and or through exploitation of operational flexibility contingent on exchange rate realizations in this environment the firm must trade off fixed operating costs switching costs and the economic benefits derived from exploiting differentials in factor costs and corporate tax rates a multinomial approximation of correlated exchange rate processes is proposed that leads to a consistent and tractable lattice model for this compound option valuation problem we then demonstrate how the global manufacturing strategy planning model framework can be utilized to analyze financial and operational hedging strategies

willingness to pay and compensation demanded experimental evidence of an unexpected disparity in measures of value aside from possible income effects measures of the maximum amounts people will pay to avoid a loss and the minimum compensation necessary for them to accept it are generally assumed to be equivalent unexpectedly wide variations between these sums however have been noted in survey responses to hypothetical options this paper reports the results of a series of experiments that confronted people with actual money payments and cash compensations the results indicate that the compensation measure of value seems to exceed significantly the willingness to pay measure which would appear to call into some question various rules of entitlement damage assessments and interpretations of indifference curves

a hotelling faustmann explanation of the structure of christmas tree prices we examine the relationship between a tree price and a tree age height using a hotelling faustmann type model of optimal plantation management which accounts for the possibility of replanting and biological growth the model predictions are tested using the data on christmas tree prices in north carolina collected in december 1997 the estimates show that in general the rates of change in prices between adjacent age cohorts reflect a competitive equilibrium in the capital market thus supporting the hotelling faustmann paradigm rigorous empirical testing of the basic economic models of optimal natural resource pricing has proven to be difficult the source of the difficulty has been the unavailability of micro level data on either prices or extraction harvest rates for in situ resource stocks 1 for nonrenewable resources hotelling s famous pricing rule has rarely been tested with firm level data stollery s study of the international nickel company of canada supported hotelling s rule and miller and upton s study of oil company values supported a corollary called the hotelling valuation principle most other studies such as halvorsen and smith and farrow have refuted this bedrock of natural resource economics in fact two studies of old growth timber essentially a nonrenewable resource provide some of the most compelling support for the hotelling model berck johnson

hotelling confronts capm a test of the theory of exhaustible resources a model of pricing of natural resource commodities that integrates financial and product markets is derived and tested the model unifies two strands of the economic and financial literature one that builds on the hotelling model of pricing of exhaustible resources and the other that extends the capital asset pricing model of pricing risky assets tests of the predictions make use of a cost function that was estimated from a panel of small canadian copper mines young 1992 the authors tests fail to reject the theoretical restrictions that are implied by the hotelling capital asset pricing model

energy and depletable resources economics and policy 1973 1998 abstract this paper reviews the impact of the literature in depletable resources and energy economics over the period 1973 1998 particularly the initial period of publication of the journal of environmental economics and management 1974 1998 a discussion of prominent policy issues in this arena is provided along with an indication of what academic economics papers have contributed to that debate this is followed by a citation analysis of contributions in the fields of energy and exhaustible resource economics for each of these two fields a list of the top papers in each five year period from 1974 to 1998 is presented along with a list of the top journals in each decade based on average citations per article the top ten cited articles in the fields in the journal of environmental economics and management are also presented

a new meta analysis on the wtp wta disparity abstract this study reports a new meta analysis of papers that elicit willingness to pay wtp and willingness to accept compensation wta measures of value for the same good we investigate the effects of type of good and several survey design features on the wtp wta disparity measured as the logarithm of the ratio of mean wta to mean wtp confirming horowitz and mcconnell s 2002 pioneering meta analysis we find the disparity is smaller for ordinary private goods than for public and non market goods that it is not solely an artifact of using hypothetical transactions or other weak experimental or survey methods and that it is smaller for studies using student subjects in addition we find that the disparity is smaller when subjects have experience valuing the good in real markets or through repeated experimental trials in contrast to horowitz and mcconnell we find the disparity is significantly smaller in studies using incentive compatible elicitation mechanisms the disparity is smaller in more recent studies an effect that is attributable only in part to changes in study characteristics

the role of responsibility in strategic risk taking we explore play between groups where one member of each 2 person group dictates the play of that group and is therefore responsible for the payoff of the other group member we compare this to play when the game is the same but each person is playing only for herself consistent with the principle of responsibility alleviation described by charness charness g 2000 responsibility and effort in an experimental labor market journal of economic behavior and organization 42 375 384 we find that a sense of responsibility for the welfare of others has an effect while the issue of responsibility does not appear to influence the decisions of 2 3 of the population almost 90 percent of the remaining 1 3 of the population plays a less risky strategy when choosing for a group than when playing only for herself

modeling manufacturing and marketing options in international operations abstract in this paper we model and compare eight manufacturing marketing options that a firm with operations in two countries termed as an international enterprise may adopt manufacturing factors incorporated in the model include factory location inventory economies of scale product design and postponement marketing factors include product positioning and pricing the model also includes international factors such as the exchange rate and transportation cost the first two options are termed core product options where the international enterprise manufactures a core product in a single facility located in one of the countries under the first core product option this facility also performs additional operations on the core product to develop custom tailored products under the second core product option customization of the core product takes place in facilities located in both countries the other six options are characterized by standardization customization of product and pricing policies as well as centralization decentralization of the production function the main result of the analysis is that under certain production related conditions the core product options dominate the other six manufacturing marketing options this result has significant managerial implications since it suggests that the core product options exploit the best of both worlds customized pricing and product policies as well as savings derived from economies of scale from the centralized production of the core product

values of gains and losses reference states and choice of measure the available empirical evidence continues to suggest that people commonly value losses more and often much more than otherwise commensurate gains consequently current practice of using the wtp measure for all changes is often likely to lead to misleading assessments of welfare changes the reference dependence of preferences implies instead that while the wtp measure is appropriate for gains the value of both positive and negative changes in the domain of losses will usually be more accurately assessed with the wta measure
