optimal failure rates and penalty bonus policies in the offshore petroleum sector we characterize optimal time profiles of risk reducing expenditures and wreck probabilities for petroleum platforms the input to our analysis is the development of wreck cost direct and imputed particular attention is paid to the question of how private companies deviating from socially optimal standards may be induced to comply with such standards by means of a a time variant penalty b a no wreck bonus and c a time invariant penalty

defining the value of a statistical life reply abstract in general empirical estimates of the value of a statistical life vsl are biased however as pointed out by blomqvist 2001 a true blip in the hazard rate can be used to obtain an exact estimate of the vsl the question remains whether individuals and markets are able to value such short drops in the hazard rate

measuring risk reduction benefits with discounted longevity there are many ways to assess the benefits and costs of risk reduction policies this paper shows that discounted longevity as a measure of benefits and the negative of net output as a measure of costs can be deduced from the shepard and zeckhauser utility maximization model

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

ageing health and health care the population in the developed world has experienced a significant increase in life expectancy over the last 50 years simultaneously while the onset of comorbidities has been deferred to older age groups health care expenditure has grown dramatically primarily owing to the advancement of medical technology and the expansion of individual income levels along with population ageing in the wake of increased longevity however the contribution of population ageing to health expenditure growth is subject to some theoretical and empirical scrutiny this paper takes the question of ageing and health and health care to the data to evaluate the net impact of ageing we focus on two main questions namely the welfare valuation of longevity improvements for various oecd countries along with the red herring hypothesis which suggests that population ageing has a small and almost negligible impact on health care expenditure our estimates lead us to suggest an average gain in longevity of 4 5 years since 1980 corresponding to about 13 5 per cent of lifetime income of a 20 year old in 2000 furthermore we confirm a weak red herring claim that is that population ageing accounts for only a 0 5 per cent annual growth rate of health care expenditure finally we find that the rise in longevity leads to a further demand for life prolonging medical care

explaining differences in public sector efficiency evidence from russia s regions summary using the case of russia s regions this paper extends the literature on public sector efficiency in three directions an attempt to better understand differences in public sector efficiency through the study of subnational governments in one country the first examination of public sector efficiency of subnational governments in emerging markets and the first study of public sector efficiency in russia three types of scores of public sector performance and efficiency indicate substantial differences across regions an econometric examination suggests that they are largely explained by per capita income the share of federal transfers in subnational government revenue quality of governance and democratic control and the level of spending

fiscal policy and regional output volatility evidence from russia eller m fidrmuc j and fungac ova z fiscal policy and regional output volatility evidence from russia regional studies this paper investigates the relationship between fiscal policy and output volatility in russian regions between 2000 and 2009 accounting for endogeneity between output volatility and fiscal developments by using system generalized method of moments gmm estimation techniques the results indicate that discretionary fiscal policy contributes to output volatility and induces macroeconomic instability at the regional level in russia this corroborates previous studies using cross country data to reduce business cycle fluctuations it would be necessary to curtail procyclical fiscal activism at the regional level e g via fiscal rules and sound institutions of fiscal federalism

growth in post soviet russia a tale of two transitions abstract in the early stages of post soviet russia s economic transition small scale entrepreneurial activity appeared to be a strong engine of growth moreover striking regional variations in initial conditions and adopted policy reforms appeared useful in accounting statistically for observed regional variations in entrepreneurial activity here we investigate whether these relationships have persisted as russia s transition has continued to evolve and find that they have not we then document that the emergence of bank issued credit virtually non existent outside of moscow prior to 2000 has been an important engine of growth since 2000 thus to date russia s post soviet development appears as a tale of two distinct transition paths

the effect of increased longevity on capital accumulation one of the more startling demographic trends of the 1970 s has been the sharp rise in lifespan in the united states between 1970 and 1980 the life expectancy of 25year old men and women increased by at least two years while longevity has been steadily rising for many decades the recent spurt has hastened the trend the increase for both men and women in the 1970 s more than doubled the improvement of the 1960 s 1 the 1970 s were also characterized by a decline in labor force participation of older workers although rising income and increased disability payments may have explained some of the decline donald parsons 1980 it seems clear that expanding longevity has not been strongly associated with deferred retirement daniel hamermesh 1984 2 thus the retirement years have assumed greater importance in financial planning for the consumer as he or she retires earlier and lives longer the traditional life cycle model would predict greater savings rates as consumers increase accumulation of assets for their retirement consumption while young would drop and there might be an increase in labor supply as individuals substitute leisure while young for greater levels of life cycle consumption even under a social security system as long as the current generation s tax liabilities reflect their longer lifespan total savings private plus public should also rise 3 the predicted increase in savings is substantial a simple example using the modigliani ando brumberg life cycle model can illustrate the extent of the savings shift assume that earnings and consumption are constant over working years and lifespan respectively and that the interest rate is zero consumption is then a constant proportion k of earnings where k is the ratio of working years to one s lifespan if consumers made plans based on average lifespan the representative 25 year old would have saved 18 percent of earnings in 1970 1 40 49 when he plans to retire at age 65 and expects to live until age 74 in 1980 after a rise in life expectancy of two years the representative 25 year old would have increased savings to 21 percent of earnings or a net rise in the savings rate per worker of 17 percent that is this simple life cycle model implies that savings in the last decade should have risen other things held constant by approximately 17 percent or about 80 billion dollars per year the evidence from aggregate time series data appears to contradict the life cycle model s prediction of rising savings rates the net private savings rate in the united states declined from 7 8 percent of nnp in 1970 to 6 2 percent in 1980 while alan auerbach 1982 has suggested that some of the reported decline in savings may be caused by mismeasurement it seems clear that there has been no substantial rise in the savings rate there are numerous explanations for department of economics university of virginia charlottesville va 22901 i am grateful to maxim engers daniel hamermesh william r johnson laurence j kotlikoff john strauss and especially james davies and john r wolfe for helpful suggestions and comments life table data can be found in daniel hamermesh 1985 the life insurance fact book various years or in unpublished form from the national center for health statistics 2john wolfe 1983 provides an ingenious argument for why the social security benefit schedule has induced those with shorter life expectancies to retire early we might therefore expect some rise in the average retirement age as those expecting to live longer defer retirement until age 65 3if the social security taxes do not rise as expected lifespan increases perhaps because current tax proceeds are paid out as current benefits rather than retained in a trust fund young workers will save more to offset the lower expected benefits in the future 4in a two period model the percentage change in savings by the young is equal to the percentage change in aggregate savings

a tale of two reforms i identify the absence of well functioning product markets in transition economies as a sufficient condition under which big bang reduces output initially while a chinese style reform increases output big bang dismantles central planning or centralized organization of production permitting monopolistic and vertically interdependent enterprises to pursue their own monopoly profits by restricting output and inter firm trade to the detriment of the economy as a whole the chinese reform by maintaining central planning but allowing enterprises to produce for the emerging product markets after they have fulfilled their output quotas under planning gives enterprises incentives to expand output beyond planned targets

intergenerational flows of time and goods consequences of slowing population growth it is feared that low fertility and older age distributions in the developed countries might cause lower life cycle consumption because of the increased pension and health cost burden the theoretical literature on intergenerational transfers has addressed this question but has considered only the consumption of market goods and has made no serious empirical attempt to measure the theoretical concepts necessary to assess the problem this paper develops a theoretical model of intergenerational transfers incorporating time use with the aid of time budget and consumer expenditure surveys empirical estimates of the age profiles of various types of time and goods consumption are presented and we conclude that 1 the net direction of intergenerational transfers is from younger to older ages 2 under the golden rule assumption these transfers largely constitute an externality to childbearing and 3 they are not large enough to offset the capital dilution effect that would result from higher fertility a

public goods and the value of product quality regulations the case of food safety abstract the paper examines preferences for product quality regulations our premise is that preferences for product quality regulations derive from preferences for both private and public goods the model is used to explain public attitudes toward a referendum measure to eliminate pesticide residues on food results from a survey of consumers are consistent with the conceptual model and show that preferences for public goods influence support for the product quality regulation the results help explain why consumption behavior is a poor predictor of political behavior and have implications for methods that use voting and market behavior to value public goods

the transition to a market economy pitfalls of partial reform we present a theory of a partial economic reform of a planned economy similar to the one that took place in russia since 1988 and in china earlier in such a reform some markets are liberalized in the sense that producers can sell output to whomever they want including private firms at free prices but at the same time must sell to state firms at state prices we show that such a reform can result in a substantial diversion of subsidized inputs away from state firms and toward private firms even when state firms value these inputs more the result may be a reduction of total output the simple analysis sheds light on many consequences of the soviet reform such as breakdown of coordination of production increased state policing of delivery quotas prohibitions of trading cooperatives and opposition to privatization the model also explains why partial reform failed in russia but worked in china

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

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

valuing future risks to life environmental policies that alter future mortality rates may affect both current and future generations this paper examines willingness to pay for future risk reductions from the perspective of the current generation the life cycle consumption saving model implies that an individual discounts future risks to himself at the consumption rate of interest if capital markets are perfect the consumption rate equals the market rate of interest otherwise the consumption rate exceeds the market rate and numerical results suggest that the implied discount factor may be substantial the overlapping generations model implies that a member of the current generation discounts the value of risks to future generations at the rate at which current consumption is substituted for a bequest

policy reform and growth in post soviet russia in pursuit of its transition from a command to a market economy russia has witnessed enormous regional differences in economic growth rates moreover the implementation of economic reforms has also differed markedly across regions we analyze whether regional differences in reform policies can account for regional differences in growth rates and conclude that to a considerable degree they can most notably we find that regional differences in price liberalization policies exhibit a positive direct correspondence with growth we also find that regional differences in large scale privatization exhibit a positive correspondence with the regional formation of new legal enterprises which in turn exhibits a strong positive correspondence with growth

uncertain lifetime life protection and the value of life saving abstract the analytic innovation is treating life s end as uncertain and life expectancy as partly the product of individuals efforts to self protect against mortality and morbidity risks the demand for self protection is modeled in a stochastic life cycle framework under alternative insurance options the model helps explain the trend and systematic diversity in life expectancies across different population groups as well as the wide variability in reported value of life saving estimates the analysis yields a closed form solution for individuals value of life saving that is estimable empirically it reflects the impacts of specific personal characteristics and alternative insurance options on both life expectancy and its valuation

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

parental and social valuations of child health information abstract we construct an endogenous risk model of the influence of more precise hazard information on the parental demand for child health a 256 observation data set is used to estimate the marginal value to parents and to society of risk information about the future consequences of children s body lead burdens our results indicate that the social value of risk information greatly exceeds the cost of providing it and that parents will purchase too little of this information

new evidence of regional income divergence in post reform russia this article investigates regional income convergence in russia during 2000 2008 we test the hypothesis in which income divergence across regions of the country should give place to income convergence as the country moves toward free market economy with strong market institutions the study contributes to the existing literature by using the exponential smooth autoregressive augmented dickey fuller adf unit root test in a panel setup a novel econometric technique which encompasses cross sectional dependence results show strong evidence of on going regional income divergence in post reform period

negative returns to seniority and job mobility across the program quality distribution are top public phd granting programs different we analyze a unique data set containing annual salary and detailed job and publication histories for a sample of 1 009 faculty members drawn from 53 public ph d granting economics departments empirical results suggest that all else equal 1 statistically significant negative returns to seniority exist within lower ranked but not top 15 programs 2 more frequent movers observe statistically higher annual salaries in lower ranked but not top 15 programs and 3 for each level of seniority faculty in top 15 programs are more likely to move at any point in the career than faculty in lower ranked programs

on consumer preferences and the willingness to pay for term life insurance abstract we run a choice based conjoint cbc analysis for term life insurance on a sample of 2017 german consumers using data from web based experiments individual level part worth profiles are estimated by means of a hierarchical bayes model drawing on the elicited preference structures we then compute relative attribute importances and different willingness to pay measures in addition we present comprehensive simulation results for a realistic competitive setting that allows us to assess product switching as well as market expansion effects on average brand critical illness cover and underwriting procedure turn out to be the most important nonprice product attributes hence if a policy comprises their favored specifications customers accept substantial markups in the monthly premium furthermore preferences vary considerably across the sample while some individuals are prepared to pay relatively high monthly premiums a large fraction exhibits no willingness to pay for term life insurance at all presumably due to the absence of a need for mortality risk coverage we also illustrate that utility driven product optimization is well suited to gain market shares avoid competitive price pressure and access additional profit potential finally based on estimated demand sensitivities and a set of cost assumptions it is shown that insurers require an in depth understanding of preferences to identify the profit maximizing price

growth and welfare under endogenous lifetime we study the role of endogenous healthcare choices by households to extend their expected lifetimes on economic growth and welfare in a decentralized overlapping generations economy with the realistic feature that households savings are held in annuities we characterize healthcare spending in the decentralized market equilibrium and its effects on economic growth we then identify the moral hazard effect in healthcare investments when annuity rates are conditioned on average mortality and explain the conditions under which it will lead to over investment in healthcare moreover we specify the general equilibrium effects and macroeconomic repercussions associated with this moral hazard effect calibrating our model to oecd data we find that the moral hazard effect may be substantial and implies sizeable welfare losses of approximately 1 5 at a more general level our study suggests that welfare improvements from longevity increases may be quite lower than sometimes assumed when considered in planner economies

industrial profitability and trade among the former soviet republics the break up of the soviet union claudia senik leygonie and gordon hughes this article looks at profitability and trade in the republics of the former soviet union looking at individual industries republic by republic there emerges a picture of some highly profitable sectors along with others with negative value added the most profitable industries mostly associated with oil and gas extraction are the least protected the least intensive in labour and already the most developed the least efficient industries include food processing and light industry and are the most protected ones trade patterns both within the former soviet union and with the rest of the world are unrelated to comparative advantage consequently sizable gains from trade are potentially available and the relevant industries are identified when the single trade balance constraint is replaced by constraints at the republic level it is clear that russia stands to benefit from not having to cover with its surpluses the deficits of the other republics russia again along with kazakhstan and ukraine should benefit from a shift to market based terms of trade

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

labor market estimates of the senior discount for the value of statistical life abstract this article develops the first measures of age industry job risks to examine the age variations in the value of statistical life because of the greater risk vulnerability of older workers they face flatter wage risk gradients than younger workers which we show to be the case empirically accounting for this heterogeneity in hedonic market equilibria leads to estimates of the value of statistical life age relationship that follows an inverted u shape the estimates of the value of statistical life range from 6 4 million for younger workers to a peak of 9 0 million for those aged 35 44 and then a decline to 3 8 million for those aged 55 62 the decline of the estimated value of statistical life with age is consistent with there being some senior discount in the clear skies initiative analysis

substance abuse treatment and mortality abstract drug overdose deaths which have more than doubled over the past decade represent a growing public health concern though substance abuse treatment may be effective in reducing drug abuse evidence for a causal effect of treatment on drug related mortality is lacking i analyze the effect of substance abuse treatment on mortality by exploiting county level variation in treatment facilities driven by facility openings and closings the estimates indicate that a 10 increase in facilities lowers a county s drug induced mortality rate by 2 the estimated effects persist across individual and county characteristics and further indicate that spillovers of treatment reduce other related causes of death

old age longevity and mortality contingent claims this paper analyzes the savings and longevity impacts of mortality contingent claims defined here as income measures such as annuities and life insurance under which earned income is contingent on the length of one s life the postwar increase in mandatory annuity and life insurance programs as well as the rapid increase in the life expectancy of older ages motivates a better understanding of the incentive effects that mortality contingent claims have on longevity related behavior we claim that these incentives in often alter the standard conclusions obtained about old age support when mortality is treated exogenously in particular we argue that annuities involve moral hazard effects that increase longevity and among other things introduce a positive interaction between public programs for health care and income support for the elderly programs that have grown enormously in developed countries

health care expenditure in the last months of life in oecd countries a considerable share of health care expenditure hce is spent for the care of the terminally ill this paper derives the demand for hce in the last 2 years of life from a model that accounts for age mortality risk and wealth the empirical tests are based on data of deceased members of a major swiss sick fund the empirical evidence confirms most of the hypotheses derived from the model i e i hce increases with closeness to death ii for retired individuals hce decreases with age and iii low income individuals as compared to high income individuals incur lower hce in the last months of life

longevity complementarities under competing risks many of the high expenditure health programs established by international organizations or national and subnational governments involve disease specific interventions such as measles vaccinations hiv education programs mammogram screening malaria prevention and lung cancer research typically these programs are evaluated solely upon the success or failure of their impact on the targeted disease this paper argues that such an exclusive evaluation may significantly underestimate the overall effect of disease specific interventions when multiple risks act as competing forces on life we suggest that programs that target one disease may have important spillover effects on the mortality and morbidity of other causes of death in order to better understand and evaluate the overall effects of disease specific programs it is necessary to understand and measure these spillover effects this paper provides a theoretical and empirical analysis of the incentives introduced by disease specific mortality interventions more precisely we discuss predictions about health investment incentives as implied by the competing risk model which is the empirical framework almost exclusively used to study multiple cause mortality we show that important complementary effects between niultiple causes of death operate to equalize the occurrence of the causes we argue that this complementarity should alter the evaluation of cause specific interventions by discrediting the argument that interventions are wasted because competing mortality risks are just around the corner in support of the existence of such complementarities we present substantive evidence from one of the most important public health programs ever introduced in developing countries the expanded programme on immunization epi of the united nations the paper is organized as follows section i provides a theoretical analysis arguing that the competing risk model of multiple causes of mortality corresponds to the leontief production function of survival this implies that there are inherent complementarities between investments in the prevention of cause specific mortality risks both on the individual level and on the aggregate level for competing risks the marginal benefit of investing to avoid one cause of death increases as a function of the survival rates of other causes the implications of this complementarity are important and have not received sufficient attention in theoretical or practical evaluations of causespecific interventions when mortality is treated as exogenous a disease specific intervention may seem wasteful if members of the targeted group are likely to die from a second cause as soon as the first has been eliminated then reducing the mortality from one cause of death would not appear to substantially increase life expectancy indeed this argument is repeatedly made by economists and demographers about medical care interventions in old age however it is sguided to use the preintervention background mortality when assessing the effectiveness of an interventionbehavior under one policy should not be assumed to prevail under a new policy as the leontief nature of competing risks predicts health investments will be focused upon he most immediate cause of death so that there are dow department of health policy and administration cb 7400 university of north carolina chapel hill nc 27599 philipson irving b harris graduate school of public policy studies department of economics and the law school university of chicago 1155 east 60th street chicago il 60637 sala i martin department of econornics columbia university 420 west 118th street 1005 new york ny 10027 and universitat pompeu fabra we are thankful to three anonymous referees for comments that substantially improved the paper and we especially acknowledge the contributions of jessica holmes who was a research assistant and co author on early drafts of this work we also thank gary becker kate howe steen jorgenson casey mulligan sherwin rosen paul schultz and participants at numerous workshops for discussions dow acknowledges financial support from national institute on aging grant no t32 ag00244 philipson from the national science foundation and the rockefeller foundation this research was begun while all authors were at yale university during 1994

pricing and r d when consumption affects longevity we analyze goods for which the amount of consumption determines the duration of consumption focusing on health related consumption that affects longevity the characteristics of the demand for such goods lead to unique predictions about private pricing and investment in r d as well as the fiscal effects of public subsidies and taxes in particular we argue that there is an r d feedback for such goods when the market size expands through longevity induced population growth we also argue that as developed countries devote large shares of public spending to old age programs that may themselves affect longevity e g medicare and social security the nonstandard effects that these programs introduce may become increasingly important

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

the welfare value of fda s mercury in fish advisory a dynamic reanalysis assessing the welfare impact of consumer health advisories is a thorny task recently shimshack and ward 2010 studied how u s households responded to fda s 2001 mercury in fish advisory they found that the average at risk household reduced fish consumption by 21 resulting in a 17 reduction in mercury exposure at the cost of a 21 reduction in cardioprotective omega 3 fatty acids based on a static assessment of the health costs and benefits shimshack and ward concluded that the advisory policy resulted in an overall consumer welfare loss in this note we propose a dynamic assessment that links the long term cardiovascular health effects of the advisory to life cycle consumption we find that under reasonable assumptions the welfare loss might be much larger than suggested our analysis highlights the importance of accounting for dynamic effects when evaluating persistent changes in exposure to environmental health risks
