introducing incentives in the market for live and cadaveric organ donations we evaluate the introduction of monetary incentives in the market for live and cadaveric organ donations we show that monetary incentives would increase the supply of organs for transplant sufficiently to eliminate the very large queues in organ markets and the suffering and deaths of many of those waiting without increasing the total cost of transplant surgery by more than about 12 percent we build on the value of life literature and other parts of economic analysis to estimate the equilibrium cost of live transplants for kidneys and livers we also show that market price for kidneys will be determined by the cost of live donations even though most organs will come from cadavers

estimating the value of a statistical life the importance of omitted variables and publication bias measures of public preferences toward risk are critical to evaluations of public policies on many safety environmental and health issues in this paper we provide a method for measuring the revealed preferences for safety risks from state level public choices about speed limits the idea is to measure the value of the time saved per incremental fatality that results from the voluntary adoption of an increased speed limit since adopters must have valued the time saved by greater speeds more than the fatalities created this ratio provides a convincing and credible upper bound on the value of a statistical life vsl

optimal regulation with unknown demand and cost functions abstract this paper presents an analysis of optimal regulation of a firm that has private information about both its cost and demand functions an earlier paper on the same topic lewis and sappington rand j econ 19 1998 438 457 is reviewed a difficulty with their analysis is discussed and an alternative formulation of their model is proposed two broad classes of problem are considered i the case where social and private incentives are roughly aligned which implies optimal prices are weakly above marginal costs and ii the case where social and private incentives diverge which implies pricing below marginal cost may be optimal journal of economic literature classification numbers d42 d82 l51

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

tax incidence when individuals are time inconsistent the case of cigarette excise taxes abstract one of the most cogent criticisms of excise taxes is their regressivity with lower income groups spending a much larger share of their income on goods such as cigarettes than do higher income groups we argue that traditional quantity based measures of incidence are only appropriate under a very restrictive time consistent model of consumption of sin goods a model that is much more consistent with existing evidence on smoking decisions is a time inconsistent formulation where excise taxes on cigarettes serve a self control function that is valued by smokers who would like to quit but cannot this self control function benefits lower income groups more since they have a significantly higher price sensitivity of smoking calibrations show that as a result cigarette taxes are much less regressive than previously assumed and are even progressive for a wide variety of parameter values

measuring the distribution of material well being u s trends abstract economists with a few exceptions have automatically assumed that the important measure of well being is income in contrast economic historians have broadened the measure of well being with particular interest in mortality morbidity nutrition education and leisure when one takes this broader view of the standard of living there appears to be a strong trend toward more equality in the distribution of well being since the industrial revolution gini coefficients calculated for the distributions of lifespan and educational attainment have declined dramatically since the mid nineteenth century for the united states mortality and educational differentials have also declined inequality of leisure time and consumption though not as consistently measured also show trends toward equality over the twentieth century these trends toward equality in well being as measured by indicators other than income and wealth seem to be generated by provision of public goods natural boundaries to lifespan educational attainment and leisure and by the growth in mean per capita income the divergent trends in the distributions of income and the other measures of well being caution against reliance on the distribution of income to interpret trends in inequality

the role of site and job characteristics in hedonic wage models recent economic analyses of wage rate differentials have generally used some form of hedonic framework in explaining the observed wage structure while these studies have adopted this common theoretical justification the models have been used to serve two distinct objectives the first of these is an empirical test of the theory of equalizing differences originally introduced by adam smith in such applications see brown 7 lucas 26 olson 28 thaler and rosen 36 and viscusi 40 as examples specific job characteristics measured with technical information or with worker perceptions have been used to explain differences in wage rates across individuals and jobs while there are a number of these studies there has not been a consistent pattern of support for the theory indeed with the exception of job risks many characteristics that a priori would be expected to lead to equalizing differences have often exhibited incorrect and or statistically insignificant measured effects on wages the second use for wage models has been as the basis for an index of the quality of life in urban areas in this framework households are assumed to select residential locations so as to maximize their individual welfare migration between cities provides the mechanism for an equilibrium household assignment under ideal conditions the pattern of equilibrium wage rates reflects the attributes of the cities involved see hoch 20 izraeli 23 cropper lo cropper and arriaga salinas 111 and rosen 31 as examples the purpose of this paper is to develop a model for wage rate differentials that includes both job and site characteristics and to estimate the model with a large micro data set our wage models provide estimates of a market clearing envelope which includes each of two types of past analyses as a

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

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

the insurance value of medical innovation abstract economists think of medical innovation as a valuable but risky good producing health benefits but increasing financial risk for consumers and healthcare payers this perspective overlooks how innovation can lower physical risks borne by healthy patients facing the prospect of future disease we present an alternative framework that accounts for all these sources of value and links them to the value of healthcare insurance we show that any innovation worth buying reduces overall risk and generates positive insurance value on its own we conduct a stylized numerical exercise to assess the potential empirical significance of our insights our calculations suggest that conventional methods meaningfully understate the value of historical health gains and disproportionately undervalue treatments for the most severe illnesses where physical risk to consumers is the costliest these calculations also suggest that the value of physical insurance from new technologies may exceed the financial spending risk that they pose

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

do the near elderly value mortality risks differently wage hedonic models are estimated with the health and retirement study to measure the risk wage tradeoffs value of statistical lives for older workers the analysis explicitly allows for multiple employment states including retirement using a multinomial selection model the results suggest that the oldest and most risk averse workers require significantly higher not lower compensation to accept increases in job related fatality risks

the implicit valuation of risks to life a comparative analysis abstract this paper reports estimates of the implicit valuation of risk reductions for different sources of risk on the job accidents and exposure to air pollutants a hedonic wage model estimated using the may 1978 current population survey for individuals in 44 smsa s provides the basis for the estimates of implicit values of risk the findings suggest quite different valuations of comparable risk changes

compensating wage differentials and the duration of wage loss a formal model of occupational choice is developed that shows the extent to which the compensation for increased duration exceeds that for increased risk using the panel study of income dynamics linked to industry data on injuries and unemployment we find nearly all the compensating wage differential for losses due to workplace injuries is for increases in the duration of loss and similarly for losses due to cyclical unemployment the compensating differentials for risk of injury are larger for union than for nonunion workers while those for cyclical unemployment are smaller for union workers

the welfare effects of environmental taxation recent literature has investigated whether the welfare gains from environmental taxation are larger or smaller in a second best setting than in a first best setting this question has mainly been addressed indirectly by asking whether the second best optimal environmental tax is higher or lower than the first best pigouvian rate even this indirect question has itself been approached indirectly comparing the second best optimal environmental tax to a proxy for its first best value marginal social damage msd on closer examination however msd becomes ambiguously defined and variable in a second best setting making it an unreliable proxy for the pigouvian rate given these observations the current analysis reevaluates these welfare questions and finds that when compared directly to its first best value the second best optimal environmental tax generally rises with increased revenue requirements even in cases where the second best environmental tax is lower than its first best value the welfare gains may be greater than in a first best setting these results suggest that the marginal fiscal benefit revenue recycling effect exceeds the marginal fiscal cost tax base effect over a range of environmental tax rates that for benchmark models extends above the first best pigouvian rate these findings reinforce the intuition that environmental policy complements rather than competes with the provision of other public goods

public health investments and the infant mortality gap evidence from federal sanitation interventions on u s indian reservations abstract to what extent do differential levels of investment in public health inputs explain observed differences in health outcomes across socioeconomic and racial groups this study investigates the impact of 3700 projects that were part of a widespread federal initiative to improve sanitation infrastructure on u s indian reservations starting in 1960 sanitation investment substantially reduced the cost of clean water for households leading to sharp reductions in both waterborne gastrointestinal disease and infectious respiratory disease among native american infants the sanitation program was quite cost effective in part because improvements in the overall disease environment also reduced infectious respiratory disease among nearby white infants despite the health externalities federal sanitation interventions explain almost forty percent of the convergence in native american and white infant mortality rates in reservation counties since 1970

the cost per life saved cutoff for safety enhancing regulations this article develops a model of the conditions under which risk regulations that are too expensive have net adverse health effects two principal components of this relationship are the implicit value of life and the income elasticity of risky behaviors using new empirical estimates for the income elasticity of many of the most consequential risk related behaviors our results imply that a 15 million decrease in income is associated with the loss of an additional statistical life regulations that cost more than 15 million per expected life saved will have counterproductive effects on individual mortality jel lsi 112 j17

housing prices health effects and valuing reductions in risk of death abstract by combining estimates of the effect of air pollution on both property values and human health risks it may be possible to draw inferences about individuals valuations of risk although valuations thus derived must be interpreted carefully they may be of use in determining the welfare effects of environmental and other regulatory policies

using mandated speed limits to measure the value of a statistical life in 1987 the federal government permitted states to raise the speed limit on their rural interstate roads but not on their urban interstate roads from 55 mph to 65 mph since the states that adopted the higher speed limit must have valued the travel hours they saved more than the fatalities incurred this institutional change provides an opportunity to estimate an upper bound on the public s willingness to trade off wealth for a change in the probability of death our estimates indicate that the adoption of the 65 mph limit increased speeds by approximately 4 percent or 2 5 mph and fatality rates by roughly 35 percent together the estimates suggest that about 125 000 hours were saved per lost life when the time saved is valued at the average hourly wage the estimates imply that adopting states were willing to accept risks that resulted in a savings of 1 54 million 1997 dollars per fatality with a sampling error roughly one third this value we set out a simple model of states decisions to adop

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

whose expectations augment the phillips curve abstract this letter uses consumer survey data to estimate expectations augmented phillips curves with inflation expectations disaggregated by socioeconomic and demographic groups the inflation expectations of high income college educated male and working age people play a larger role in inflation dynamics than do the expectations of other groups of consumers or of professional forecasters

the value of statistical life and the economics of landmine clearance in developing countries this paper presents estimates of the value of statistical life vsl in rural thailand using the contingent valuation cv method these estimates are applied to an economic analysis of landmine clearance the estimated vsl of us 250 000 suggests that the value of lives saved from landmine clearance is at least an order of magnitude greater than the values used in existing studies

pesticide risk valuation in empirical economics a comparative approach abstract pesticide use in agriculture poses several risks to both human health and nontarget agro ecosystems due to lack of information on the monetary value of reducing pesticide risks it is difficult to perform an economic analysis that addresses social efficiency of policy and draws conclusions about the appropriate degree of regulation the aim of the current paper is to present a critical overview of the empirical literature on pesticide risk valuation that provides disaggregate willingness to pay estimates wtps of pesticide risks reduction recent multidimensional classification methods such as coined decision tree analysis are used in a comparative approach as tools for explaining the differences in empirical research findings the analysis shows that the order of magnitude of wtps is related to both the valuation technique and to the data available from biomedical and ecotoxicological literature it also shows that wtp estimates of pesticide risks cannot be simply averaged over several empirical studies the order of magnitude of a wtp estimate is in fact related to the specific type of risk and to the nature of the risk scenario considered as well to lay people s subjective perception of risks

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

valuing changes in health risks a comparison of alternative measures essential to efficient provision of health safety and the environment is correct valuation of risks to human health in a world of scarcity difficult decisions concerning tradeoffs between health and other desirables are unavoidable in this paper we develop a model of health investment under uncertainty which yields a general expression for values of changes in risks to human health the preference based values of morbidity risks and mortality risks are ex ante dollar equivalents of changes in expected utility associated with risk changes the preference based values are related to two alternative measures costs of illness and preventive expenditures which are thought to be lower bounds on the value of risk reductions we demonstrate that these alternative measures are not even special cases of the more general measure and that the size relationships among the three measures are complex also we derive the relationship between the willingness to pay for risk changes and the consumer surpluses associated with health changes which occur with certainty the next section contains a brief review of the approaches to valuing changes in health

u s war costs two parts temporary one part permanent military spending fatalities and the destruction of capital all of which are immediately felt and are often large are the most overt costs of war they are also relatively short lived but the costs of war borne by combatants and their caretakers which includes families communities and the modern welfare state tend instead to be lifelong in this paper i show that a significant component of the budgetary costs associated with u s wars is long lived one third to one half of the total present value of historical war costs are benefits distributed over the remaining life spans of veterans and their dependents even thirty years after the end of hostilities typically half of all benefits remain to be paid estimates of the costs of injuries and deaths suggest that the private burden of war borne by survivors namely the uncompensated costs of service related injuries are also large and long lived

automobile externalities and policies this paper discusses the nature and magnitude of externalities associated with automobile use including local and global pollution oil dependence traffic congestion and traffic accidents it then discusses current federal policies affecting these externalities including fuel taxes fuel economy and emissions standards and alternative fuel policies summarizing insofar as possible the welfare effects of those policies finally we discuss emerging pricing policies including congestion tolls and insurance reform and summarize the appropriate combination of policies to address automobile externalities

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

gender firm size industry and estimates of the value of life two national probability samples are used to investigate four empirical questions associated with estimating the value of life using coefficients from wage regressions the four questions pertain to whether wage regression coefficients on fatality rate variables are sensitive to 1 including or excluding women from the sample 2 definitions of the fatality rate which include estimates of either male only or female only deaths 3 removing the influence of firm size from the fatality rate or the wage rate 4 respondents inaccuracies in reporting their three digit industry problems associated with 3 and 4 are found to be minimal problems associated with 1 and 2 also appear to be small if the goal is to estimate the value of life for men
