the diffusion of health technologies cultural and biological divergence abstract this paper proposes the hypothesis that genetic distance to the health frontier influences population health outcomes evidence from a world sample suggests that genetic distance interpreted as long term cultural and biological divergence is an important factor in understanding health inequalities across countries specifically the paper documents a remarkably robust negative link between genetic distance to the united states and population health as measured by life expectancy at birth and the adult survival rate even after accounting for an extensive set of possible confounders such as gdp per capita and various climatic factors consistent with the interpretation that genetic distance is related to population health indirectly through human barriers to the diffusion of modern health technologies the evidence indicates that the gene gradient emerges at the onset of the international epidemiological transition

human capital inequality life expectancy and economic growth this article presents a model in which inequality affects per capita income when individuals decide to invest in education taking into account their life expectancy which depends to a large extent on the human capital of their parents our results show the existence of multiple steady states depending on the initial distribution of education the low steady state is a poverty trap in which children raised in poor families have low life expectancy and work as non educated workers the empirical evidence suggests that the life expectancy mechanism explains a major part of the relationship between inequality and human capital accumulation increases in life expectancy and human capital accumulation have accelerated since the post world war ii period in most parts of the world however in spite of the convergence in life expectancy across countries during this period see for example becker et al 2005 in 2000 there was still an immense gap between the rich and the poor world life expectancy was 78 years in oecd countries but only 47 years in sub saharan africa where the gap with rich countries is increasing nowadays due to aids being widespread likewise the striking disparities in human capital are also evident whereas the secondary school enrolment rate was almost 100 in rich countries more than 70 of children in sub saharan africa were not enrolled in secondary schooling and therefore entered the labour market as unskilled workers from childhood these disparities in schooling are also accompanied by huge differences in the distribution of education thus the human capital gini coefficient in sub saharan africa 0 56 is twice as high as that of oecd countries 0 21 in this article we argue that high human capital inequality low life expectancy and low human capital accumulation rates reinforce each other and may explain the persistence of poverty in a great part of the world

the pricing of options on assets with stochastic volatilities one option pricing problem that has hitherto been unsolved is the pricing of a european call on an asset that has a stochastic volatility this paper examines this problem the option price is determined in series form for the case in which the stochastic volatility is independent of the stock price numerical solutions are also produced for the case in which the volatility is correlated with the stock price it is found that the black scholes price frequently overprices options and that the degree of overpricing increases with the time to maturity one option pricing problem that has hitherto remained unsolved is the pricing of a european call on a stock that has a stochastic volatility from the work of merton 12 garman 6 and cox ingersoll and ross 3 the differential equation that the option must satisfy is known the solution of this differential equation is independent of risk preferences if a the volatility is a traded asset or b the volatility is uncorrelated with aggregate consumption if either of these conditions holds the risk neutral valuation arguments of cox and ross 4 can be used in a straightfoward way this paper produces a solution in series form for the situation in which the stock price is instantaneously uncorrelated with the volatility we do not assume that the volatility is a traded asset also a constant correlation between the instantaneous rate of change of the volatility and the rate of change of aggregate consumption can be accommodated the option price is lower than the blackscholes b s 1 price when the option is close to being at the money and higher when it is deep in or deep out of the money the exercise prices for which overpricing by b s takes place are within about ten percent of the security price this is the range of exercise prices over which most option trading takes place so we may in general expect the b s price to overprice options this effect is exaggerated as the time to maturity increases one of the most surprising implications of this is that if the b s equation is used to determine the implied volatility of a near the money option the longer the time to maturity the lower the implied volatility numerical solutions for the case in which the volatility is correlated with the stock price are also examined the stochastic volatility problem has been examined by merton 13 geske 7 johnson 10 johnson and shanno 11 eisenberg 5 wiggins 16 and

the value of vaccination despite advances during the twentieth century immunization coverage is far from universal and faces significant obstacles in both developing and developed countries weak policy emphasis on vaccination may be the result of the narrow view of its benefits in scientific and policy making communities which focus mainly on the averted costs of medical treatment an investigation of the broader impacts of immunization shows that the benefits of vaccine programs in particular their economic effects via improved health have been underestimated thereby causing the rate of return to be underestimated

a review of angus deaton s the great escape health wealth and the origins of inequality this book explores the relationship between the material standard of living and health both across countries and over time above all deaton is interested in the question of whether income growth contributes significantly to better health his answer is no saving lives in poor countries is not expensive and there are many episodes of massive health improvements in the absence of income growth as an alternative he argues that the cross sectional correlation between health and income is induced by variation in institutional quality while over time parallel improvements in income and health have been a result of advancing knowledge

disease and development the effect of life expectancy on economic growth we exploit the major international health improvements from the 1940s to estimate the effect of life expectancy on economic performance we construct predicted mortality using preintervention mortality rates from various diseases and dates of global interventions predicted mortality has a large impact on changes in life expectancy starting in 1940 but no effect before 1940 using predicted mortality as an instrument we find that a 1 percent increase in life expectancy leads to a 1 7 2 percent increase in population life expectancy has a much smaller effect on total gdp however consequently there is no evidence that the large increase in life expectancy raised income per capita

disease and development revisited acemoglu and johnson 2007 present evidence that improvements in population health do not promote economic growth we show that their result depends critically on the assumption that initial health has no causal effect on subsequent economic growth we argue that such an effect is likely primarily because childhood health affects adult productivity in our augmented model which includes initial health the instrumental variable proposed by acemoglu and johnson has no significant predictive power for improvements in health and does not identify the effect of contemporaneous improvements in health on economic growth this abstract was borrowed from another version of this item

mother s education and the intergenerational transmission of human capital evidence from college openings we examine the effect of maternal education on birth outcomes using vital statistics natality data from 1970 to 1999 we also assess the importance of four channels through which maternal education may improve birth outcomes use of prenatal care smoking marriage and fertility in an effort to account for the endogeneity of education attainment we use data about the availability of colleges in the womans country in her 17th year as an instrument for maternal education we find that higher maternal education improves infant health as measured by birth weight and gestational age it also increases the probability that a new mother is married reduces parity increases use of prenatal care and reduces smoking suggesting that may be important pathways for the ultimate effect on health our results add to the growing body of literature which suggests that estimates of the returns to education which focus only on increases in wages understate the total return

redistribution pork and elections why might citizens vote against redistributive policies from which they would seem to benefit many scholars focus on wedge issues such as religion or race but another explanation might be geographically based patronage or pork we examine the tension between redistribution and patronage with a model that combines partisan elections across multiple districts with legislation in spatial and divide the dollar environments the model yields a unique equilibrium that describes the circumstances under which poor voters support right wing parties that favor low taxes and redistribution and under which rich voters support left wing parties that favor high taxes and redistribution the model suggests that one reason standard tax and transfer models of redistribution often do not capture empirical reality is that redistributive transfers are a less efficient tool for attracting votes than are more targeted policy programs the model also underlines the central importance of party discipline during legislative bargaining in shaping the importance of redistribution in voter behavior and it describes why right wing parties should have an advantage over left wing ones in majoritarian systems

capital and labor saving technical change in an aging economy does population aging and the associated increase in the old age dependency ratio affect economic growth the answer is given in a novel analytical framework that allows for population aging to affect endogenous capital and labor saving technical change the short run analysis reveals that population aging induces more labor and less capital saving technical change as it increases the relative scarcity of labor with respect to capital due to external contemporaneous knowledge spill overs across innovating firms induced technical change has a first order effect on current aggregate income in the long run capitalsaving technical progress vanishes and the economy s growth rate reflects only labor saving technical change however the mere possibility of capital saving technical change is shown to imply that the economy s steady state growth rate becomes independent of its age structure neither a higher life expectancy nor a decline in fertility affects economic growth in the long run

infant health and longevity evidence from a historical intervention in sweden this paper investigates the potential of an infant intervention to improve life expectancy contributing to emerging interest in the early life origins of chronic disease we track individuals from birth to death and are able to identify age and cause of death the intervention was pioneered in sweden in 1931 1933 and appears to have been pivotal in the emergence of universal infant care programmes in the scandinavian countries during the creation of the welfare state it provided information and support to mothers with an emphasis on nutrition and sanitation while monitoring infant care through home visits and clinics we estimate that the average duration of programme exposure in infancy led to a 1 56 point decline in the risk of infant death 24 of baseline risk and a 2 56 point decline in the risk of dying by age 75 7 0 of baseline risk and these impacts are much larger for children born out of wedlock intervention led declines in the risk of dying after the age of 50 are dominated by reductions in cancer and cardiovascular mortality we find no evidence of selective utilisation and the estimates are similar when we exploit within mother variation in outcomes less

average earnings and long term mortality evidence from administrative data in this paper we exploit a unique database that merges longitudinal earnings data on pennsylvanian workers with national death records to study the detailed nature of the corre lation between earnings and mortality we find that the estimates typically reported in the lit erature which are based on single years of earn ings data are likely to understate substantially the strength of the association between income and mortality in particular relative to a single year of earnings the average of earnings over a six year period predicts a 70 percent greater impact of income on mortality in addition con trolling for the mean level of earnings over a period we find that greater earnings volatility is associated with higher mortality we also examine the lag structure of the rela tionship between earnings and mortality we

geography health and the pace of demo economic development abstract this paper investigates the impact of subsistence consumption and extrinsic and intrinsic causes of child mortality on fertility and child expenditure it offers a theory for why mankind multiplies at higher rates at geographically unfavorable tropical locations placed into a macroeconomic framework this behavior creates an indirect channel through which geography shapes economic performance it is explained why it are countries of low absolute latitude where we observe exceedingly slow if not stalled economic development and demographic transition

option pricing under time varying risk aversion with applications to risk forecasting abstract we present a two factor option pricing model which parsimoniously captures the difference in volatility persistences under the historical and risk neutral probabilities the model generates an s shaped pricing kernel that exhibits time varying risk aversion we apply our model for two purposes first we analyze the risk preference implied by s p500 index options during 2001 2009 and find that risk aversion level strongly increases during stressed market conditions second we apply our model for value at risk var forecasts during the subprime crisis period and find that it outperforms several leading var models

poverty and survival a recent literature highlights the uncertainty concerning whether economic growth has any causal protective effect on health and survival but equal rates of growth often deliver unequal rates of poverty reduction and absolute deprivation is more clearly relevant using state level panel data for india we contribute the first estimates of the impact of changes in poverty on infant survival we identify a significant within state relationship which persists conditional upon state income indicating the size of survival gains from redistribution in favour of households below the poverty line the poverty elasticity declines over time after 1981 it is invariant to controlling for income inequality but diminished upon controlling for education fertility and state health expenditure and eliminated once we introduce controls for omitted trends

the value of socialized medicine the impact of universal primary healthcare provision on mortality rates in turkey abstract this paper examines the impact of universal free and easily accessible primary healthcare on population health as measured by age specific mortality rates focusing on a nationwide socialized medicine program implemented in turkey the family medicine program fmp launched in 2005 assigns each turkish citizen to a specific state employed family physician who offers a wide range of primary healthcare services that are free of charge furthermore these services are provided at family health centers which operate on a walk in basis and are located within neighborhoods in close proximity to the patients to identify the causal impact of the fmp we exploit the variation in its introduction across provinces and over time our estimates indicate that the fmp caused the mortality rate to decrease by 25 6 among infants 7 7 among the elderly and 22 9 among children ages 1 4 these estimates translate into 2 6 1 29 and 0 13 fewer deaths among infants the elderly and children ages 1 4 respectively furthermore the effects appear to strengthen over time we also show evidence to suggest that the fmp has contributed to an equalization of mortality across provinces finally our calculations indicate that each family physician saves about 0 15 0 46 and 0 005 lives among infants the elderly and children ages 1 4 per province every year

optimal patent policy research joint ventures and growth abstract the patent and growth studies have found that there may be welfare loss without optimizing both patent breadth and the division of profit in competitive research joint ventures njs this paper examines the effects of patent policy on an r d based growth model where innovations are produced by cooperative research joint ventures cjs we show that cjs always generate a higher equilibrium growth rate than njs and the social optimum can be achieved with cjs in equilibrium when only patent breadth is chosen optimally

rich and healthy better than poor and sick an empirical analysis of income health and the duration of the pension benefit spell i analyze the relationship between duration of the pension benefit spell and pension benefit claims from the german public pension system with a special emphasis on differential results with respect to health this relationship is crucial for a potential structural pattern of redistribution between different income and health groups induced by the public pension system evidence for such redistribution from poor to rich is present for most of the specifications in my analysis the most adequate specification is partially linear does therefore not impose any parametrical restrictions between duration and benefit claims and allows for potential endogeneity the relationship i extract is clearly positive i also find that redistribution from low income individuals to individuals with high income is more pronounced the worse the health status is despite longer benefit spells for pensioners in ill health

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

technology growth and expenditure growth in health care in the united states health care technology has contributed to rising survival rates yet health care spending relative to gdp has also grown more rapidly than in any other country we develop a model of patient demand and supplier behavior to explain these parallel trends in technology growth and cost growth we show that health care productivity depends on the heterogeneity of treatment effects across patients the shape of the health production function and the cost structure of procedures such as mris with high fixed costs and low marginal costs the model implies a typology of medical technology productivity i highly cost effective home run innovations with little chance of overuse such as anti retroviral therapy for hiv ii treatments highly effective for some but not for all e g stents and iii gray area treatments with uncertain clinical value such as icu days among chronically ill patients not surprisingly countries adopting category i and effective category ii treatments gain the greatest health improvements while countries adopting ineffective category ii and category iii treatments experience the most rapid cost growth ultimately economic and political resistance in the u s to ever rising tax rates will slow cost growth with uncertain effects on technology growth

the value of life and the rise in health spending over the past half century americans spent a rising share of total economic resources on health and enjoyed substantially longer lives as a result debate on health policy often focuses on limiting the growth of health spending we investigate an issue central to this debate is the growth of health spending a rational response to changing economic conditions notably the growth of income per person we develop a model based on standard economic assumptions and argue that this is indeed the case standard preferences of the kind used widely in economics to study consumption asset pricing and labor supply imply that health spending is a superior good with an income elasticity well above one as people get richer and consumption rises the marginal utility of consumption falls rapidly spending on health to extend life allows individuals to purchase additional periods of utility the marginal utility of life extension does not decline as a result the optimal composition of total spending shifts toward health and the health share grows along with income in projections based on the quantitative analysis of our model the optimal health share of spending seems likely to exceed 30 percent by the middle of the century

mortality transition and differential incentives for early retirement existing studies investigating the effect of mortality decline on retirement age usually specify the human mortality pattern in a parametric way and consider the derivative of optimal retirement age with respect to a change in the survival parameter however a survival parameter change affects the mortality rates at different ages simultaneously motivated by the stylized fact that mortality decline affects primarily younger people in the early phase of a mortality transition but mainly older people in the later phase we study the more fundamental question of how a mortality change at an arbitrary age affects optimal retirement age by using the volterra derivative for a functional we show that a mortality decline at an older age unambiguously leads to a later retirement age but a mortality decline at a younger age may lead to earlier retirement because of the substantial increase in the individual s expected lifetime human wealth

fatal fluctuations cyclicality in infant mortality in india this paper investigates the impact of aggregate income shocks on infant mortality in india and investigates likely mechanisms a recent oecd dominated literature reports the provocative finding that mortality at most ages is pro cyclical similar analyses for poorer countries are scarce and both income risk and mortality risk are greater in poor countries this paper uses data and methods designed to avoid some of the specification problems in previous studies and it explores mechanisms and extensions that have not been previously considered it uses individual data on infant mortality for about 150 000 children born in 1970 1997 merged by cohort and state of birth with a state panel containing information on aggregate income identification rests upon comparing the effects of annual deviations in income from trend on the mortality risks of children born at different times to the same mother conditional upon a number of state time varying covariates including rainshocks and state social expenditure rural infant mortality is counter cyclical the elasticity being about 0 33 this is despite the finding that relatively high risk women avert birth or suffer fetal loss in recessions it seems in part related to recessions stimulating distress labor amongst mothers in contrast to the case in richer countries where they discourage labor market participation health care seeking declines in recessions and this appears to be related to the opportunity cost of maternal time disaggregation reveals that the average results are driven by rural households in which the mother is uneducated or had her first birth in teenage and that it is only girls that are at risk boys are protected from income shocks exposure to poor conditions in the fetal and neonatal period appears to have a larger effect on infant mortality than similar exposure in the postneonatal period

electoral rules and political selection theory and evidence from a field experiment in afghanistan voters commonly face a choice between competent candidates and those with policy preferences similar to their own this article explores how electoral rules such as district magnitude mediate this trade off and affect the composition of representative bodies and the quality of policy outcomes we show formally that anticipation of bargaining over policy causes voters in elections with multiple single member districts to prefer candidates with polarized policy positions over more competent candidates results from a unique field experiment in afghanistan are consistent with these predictions specifically representatives selected by elections with a single multi member district are better educated and exhibit less extreme policy preferences

the behavior of risk and market prices of risk over the nasdaq bubble period we exploit the information in the options market to study the variations of return risk and market prices of different sources of risk during the rise and fall of the nasdaq market we specify a model that accommodates fluctuations in both risk levels and market prices of different sources of risk and we estimate the model using the time series returns and option prices on the nasdaq 100 tracking stock our analysis reveals three key variations during the period from march 1999 to march 2001 first return volatility increased together with the rising nasdaq index level even though the two tend to move in opposite directions second although the market price of diffusion return risk averages around 1 82 over the whole sample the estimates reached negative territory at the end of 1999 the estimates reverted back to highly positive values after the collapse of the nasdaq market third the market price of jump risk increased with the rising nasdaq valuation and this increase in market price coincided with an increased imbalance in open interest between put and call options

cyclicality mortality and the value of time the case of coffee price fluctuations and child survival in colombia recent studies demonstrate procyclical mortality in wealthy countries but there are reasons to expect a countercyclical relationship in developing nations we investigate how child survival in colombia responds to fluctuations in world arabica coffee prices and document starkly procyclical child deaths in studying this result s behavioral underpinnings we highlight that 1 the leading determinants of child health are inexpensive but require considerable time and 2 as the value of time declines with falling coffee prices so does the relative price of health we find a variety of direct evidence consistent with the primacy of time in child health production

health behavior health knowledge and schooling the positive correlation between schooling and good health is well documented one explanation is that schooling helps people choose healthier life styles by improving their knowledge of the relationship between health behaviors and health outcomes that is schooling improves the household s allocative efficiency in producing health this empirical study uses direct measures of health knowledge to test this explanation part of the relationship between schooling and the consumption of cigarettes alcohol and exercise is explained by differences in health knowledge however most of schooling s effects on health behavior remain after differences in knowledge are controlled for

economic status and health in childhood the origins of the gradient the well known positive association between health and income in adulthood has antecedents in childhood not only is children s health positively related to household income but the relationship between household income and children s health becomes more pronounced as children age part of the relationship can be explained by the arrival and impact of chronic conditions children from lower income households with chronic conditions have worse health than do those from higher income households the adverse health effects of lower income accumulate over children s lives part of the intergenerational transmission of socioeconomic status may work through the impact of parents income on children s health

the determinants of mortality mortality rates have fallen dramatically over time starting in a few countries in the 18th century and continuing to fall today in just the past century life expectancy has increased by over 30 years at the same time mortality rates remain much higher in poor countries with a difference in life expectancy between rich and poor countries of also about 30 years this difference persists despite the remarkable progress in health improvement in the last half century at least until the hiv aids pandemic in both the time series and the cross section data there is a strong correlation between income per capita and mortality rates a correlation that also exists within countries where richer better educated people live longer we review the determinants of these patterns over history over countries and across groups within countries while there is no consensus about the causal mechanisms we tentatively identify the application of scientific advance and technical progress some of which is induced by income and facilitated by education as the ultimate determinant of health such an explanation allows a consistent interpretation of the historical cross country and within country evidence we downplay direct causal mechanisms running from income to health

disease and development evidence from hookworm eradication in the american south this study evaluates the economic consequences of the successful eradication of hookworm disease from the american south the hookworm eradication campaign c 1910 began soon after i the discovery that a variety of health problems among southerners could be attributed to the disease and ii the donation by john d rockefeller of a substantial sum to the effort the rockefeller sanitary commission rsc surveyed infection rates in the affected areas eleven southern states and found that an average of forty percent of school aged children were infected with hookworm the rsc then sponsored treatment and education campaigns across the region follow up studies indicate that this campaign substantially reduced hookworm disease almost immediately the sudden introduction of this treatment combines with the cross area differences in pre treatment infection rates to form the basis of the identification strategy areas with higher levels of hookworm infection prior to the rsc experienced greater increases in school enrollment attendance and literacy after the intervention this result is robust to controlling for a variety of alternative factors including differential trends across areas changing crop prices shifts in certain educational and health policies and the effect of malaria eradication no significant contemporaneous results are found for adults who should have benefited less from the intervention owing to their substantially lower prior infection rates a long term follow up of affected cohorts indicates a substantial gain in income that coincided with exposure to hookworm eradication i also find evidence that eradication increased the return to schooling

four scenarios of development and the role of economic policy we ask which economic policies can help a country create the most favourable conditions for development we observe that the dynamics of several development indicators can be grouped into four clusters each cluster corresponding to a different combination of growth and changes in inequality based on this observation we define four different development scenarios and use limited dependent variable regressions to study how structural and policy factors affect a country s probability to achieve the most or the least favourable of these scenarios our results point to a comforting picture through the choice of appropriate policies countries can effectively increase their chances to achieve the most favourable development scenario

time to death and the forecasting of macro level health care expenditures some further considerations although the effect of time to death ttd on health care expenditures hce has been investigated using individual level data the most profound implications of ttd have been for the forecasting of macro level hce here we estimate the ttd model using macro level data from the netherlands consisting of mortality rates and age and gender specific per capita health expenditures for the years 1981 2007 forecasts for the years 2008 2020 of this macro level ttd model were compared to forecasts that excluded ttd results revealed that the effect of ttd on hce in our macro model was similar to those found in micro econometric studies as the inclusion of ttd pushed growth rate estimates from unidentified causes upwards however the two models forecasts of hce for the 2008 2020 were similar we argue that including ttd if modeled correctly does not lower forecasts of hce

do natural resources fuel authoritarianism a reappraisal of the resource curse a large body of scholarship finds a negative relationship between natural resources and democracy extant cross country regressions however assume random effects and are run on panel datasets with relatively short time dimensions because natural resource reliance is not an exogenous variable this is not an effective strategy for uncovering causal relationships numerous sources of bias may be driving the results the most serious of which is omitted variable bias induced by unobserved country specific and time invariant heterogeneity to address these problems we develop unique historical datasets employ time series centric techniques and operationalize explicitly specified counterfactuals we test to see if there is a long run relationship between resource reliance and regime type within countries over time both on a country by country basis and across several different panels we find that increases in resource reliance are not associated with authoritarianism in fact in many specifications we generate results that suggest a resource blessing

health insurance and the demand for medical care evidence from a randomized experiment we estimate how cost sharing the portion of the bill the patient pays affects the demand for medical services the data come from a randomized experiment a catastrophic insurance plan reduces expenditures 31 percent relative to zero out of pocket price the price elasticity is approximately 0 2 we reject the hypothesis that less favorable coverage of outpatient services increases total expenditure for example by deterring preventive care or inducing hospitalization

health and income a robust comparison of canada and the us abstract this paper uses sequential stochastic dominance procedures to compare the joint distribution of health and income across space and time it is the first application of which we are aware of methods to compare multidimensional distributions of income and health using procedures that are robust to aggregation techniques the paper s approach is more general than comparisons of health gradients and does not require the estimation of health equivalent incomes we illustrate the approach by contrasting canada and the us using comparable data canada dominates the us over the bottom part of the bi dimensional distribution of health and income though not generally over the uni dimensional distributions of health or income the paper also finds that welfare for both canadians and americans has not unambiguously improved during the last decade over the joint distribution of income and health in spite of the fact that the uni dimensional distributions of income have clearly improved during that period

mortality versus morbidity in the demographic transition abstract the link between the mortality and epidemiological transitions is used to identify the effect of the former on the fertility transition a mortality transition that is not accompanied by improving morbidity causes slower demographic and economic change in a model where children may die from infectious disease childhood health affects human capital and noninfectious disease related adult mortality when child mortality falls from lower prevalence as it did in western europe labor productivity improves fertility falls and the economy prospers when it falls mainly from better cures as it has in sub saharan africa survivors are less healthy and there is little economic growth the model can quantitatively explain sub saharan africa s experience more generally it shows that the commonly used indicator life expectancy at birth is a poor predictor of population health and economic growth unless morbidity falls with mortality

political complements in the welfare state health care and social security abstract all oecd countries target a large majority of their welfare spending to the elderly through public pensions and health care programs spending in both programs has largely increased in the past decades often more than the share of elderly in the population we suggest that these phenomena may be due to political complementarities between these two transfer programs we show that these two programs may coexist because public health care may increase the political constituency in favor of social security and vice versa specifically public health decreases the absolute longevity differential between low and high income individuals therefore rising the retirement period and the total pension benefits of the former relatively to the latter this effect increases the political support for social security among the low income young we show that in a political equilibrium of a two dimensional majoritarian election a voting majority of low income young and retirees supports a large welfare state the composition between public health and social security is determined by intermediate median income types who favor the contemporaneous existence of these two programs since public health increases their longevity enough to make social security more attractive technological improvements in health care strengthens this complementarity and lead to more welfare spending

the engine and the reaper industrialization and mortality in late nineteenth century japan economic development improves long run health outcomes through access to medical treatment sanitation and higher income short run impacts however may be ambiguous given disease exposure from market integration using a panel dataset of japanese vital statistics and multiple estimation methods i find that railroad network expansion is associated with a six percent increase in gross mortality rates among newly integrated regions communicable diseases accounted for most of the rail associated mortality which indicate railways behaved as transmission vectors at the same time market integration facilitated by railways corresponded with an eighteen percent increase in total capital investment nationwide over ten years

long run impacts of childhood access to the safety net a growing economics literature establishes a causal link between in utero shocks and health and human capital in adulthood most studies rely on extreme negative shocks such as famine and pandemics we are the first to examine the impact of a positive and policy driven change in economic resources available in utero and during childhood in particular we focus on the introduction of a key element of the u s safety net the food stamp program which was rolled out across counties in the u s between 1961 and 1975 we use the panel study of income dynamics to assemble unique data linking family background and county of residence in early childhood to adult health and economic outcomes the identification comes from variation across counties and over birth cohorts in availability of the food stamp program our findings indicate that the food stamp program has effects decades after initial exposure specifically access to food stamps in childhood leads to a significant reduction in the incidence of metabolic syndrome obesity high blood pressure and diabetes and for women an increase in economic self sufficiency overall our results suggest substantial internal and external benefits of the safety net that have not previously been quantified

do electoral institutions have an impact on population health there is an emerging political economics literature which purports to show that legislatures elected based on proportional electoral rules spend more and redistribute more than legislatures elected based on majoritarian electoral rules going a step further the authors of this paper consider whether degree of electoral proportionality has an impact on population health and in particular the health of the least advantaged members of society a panel of 24 parliamentary democracies for the years 1960 2004 is used to examine the relationship between electoral institutions and health the authors find that greater electoral proportionality is positively associated with overall population health as indicated by life expectancy and with the health of the poorest as indicated by a reduction in infant mortality a panel of 17 countries for the years 1970 2004 is then used to show to that electoral permissiveness modifies the impact of health spending on infant mortality

mortality and immortality the nobel prize as an experiment into the effect of status upon longevity it has been known for centuries that the rich and famous have longer lives than the poor and ordinary causality however remains trenchantly debated the ideal experiment would be one in which extra status could somehow be dropped upon a sub sample of individuals while those in a control group of comparable individuals received none this paper attempts to formulate a test in that spirit it collects 19th century birth data on science nobel prize winners correcting for potential biases we estimate that winning the prize compared to merely being nominated is associated with between 1 and 2 years of extra longevity

the economics of global health an assessment the international community through the millennium development goals and now the sustainable development goals has long recognized the critical role of improved global health in achieving social and economic development this edition of the oxford review of economic policy explores whether this importance has been mirrored in the field of economics it does so by bringing together the voices of 28 economists working on widely varying aspects of global health economics to confront three key policy questions how do we build better more equitable health systems how are global commons health problems to be overcome and how might we improve evaluation and priority setting in global health this assessment considers the degree to which these questions have been answered and extracts the key thrusts of a research agenda it suggests that as in global health itself while much has been achieved many challenges and potential achievements await in the field of global health economics

education lifetime labor supply and longevity improvements this paper presents an analysis of the differential role of mortality for the optimal schooling and retirement age when the accumulation of human capital follows the so called ben porath mechanism we set up a life cycle model of consumption and labor supply at the extensive margin that allows for endogenous human capital formation this paper makes two important contributions first we provide the conditions under which a decrease in mortality leads to a longer education period and an earlier retirement age second those conditions are decomposed into a ben porath mechanism and a lifetime human wealth effect vs the years to consume effect finally using us and swedish data for cohorts born between 1890 and 2000 we show that our model can match the empirical evidence

long term determinants of the demographic transition 1870 2000 abstract this paper analyzes the long term economic determinants of the demographic transition using a large panel of countries since 1870 a simple theoretical framework accounts for the possibly nonmonotonic variations of fertility in the course of economic development as predicted by unified growth theory i find that primary schooling rather than income or health related variables is the most robust determinant of the fertility transition as regards the health transition both education and income are significant determinants of mortality rates but education alone accounts for the bulk of their time variation over the twentieth century thus education can be viewed as the main long term determinant of the demographic transition

economic activity and the spread of viral diseases evidence from high frequency data viruses are a major threat to human health and given that they spread through social interactions represent a costly externality this article addresses three main questions i what are the unintended consequences of economic activity on the spread of infections ii how efficient are measures that limit interpersonal contacts iii how do we allocate our scarce resources to limit the spread of infections to answer these questions we use novel high frequency data from france on the incidence of a number of viral diseases across space for different age groups over a quarter of a century we use quasi experimental variation to evaluate the importance of policies reducing interpersonal contacts such as school closures or the closure of public transportation networks while these policies significantly reduce disease prevalence we find that they are not cost effective we find that expansions of transportation networks have significant health costs in increasing the spread of viruses and that propagation rates are pro cyclically sensitive to economic conditions and increase with inter regional trade jel codes i12 i15 i18 h51 c23

aggregate income shocks and infant mortality in the developing world health and income are strongly correlated both within and across countries yet the extent to which improvements in income have a causal effect on health status remains controversial the authors investigate whether short term fluctuations in aggregate income affect infant mortality using an unusually large data set of 1 7 million births in 59 developing countries the authors show a large negative association between per capita gdp and infant mortality female infant mortality is more sensitive than male infant mortality to negative economic shocks suggesting that policies that protect the health status of female infants may be especially important during economic downturns

a human development index by income groups summary one of the most frequent critiques of the hdi is that it does not take into account inequality within countries we suggest a methodology which allows to compute the three components and the overall hdi for quintiles of the income distribution this allows comparisons of the level in human development of the poor and non poor within and across countries an empirical illustration shows large discrepancies in human development within the countries especially in africa these discrepancies are lower the higher the hdi is but only weakly so inequality in income is generally higher than inequality in education and life expectancy

recovering probability distributions from option prices this article derives underlying asset risk neutral probability distributions of european options on the s p 500 index nonparametric methods are used to choose probabilities that minimize an objective function subject to requiring that the probabilities are consistent with observed option and underlying asset prices alternative optimization specifications produce approximately the same implied distributions a new and fast optimization technique for estimating probability distributions based on maximizing the smoothness of the resulting distribution is proposed since the crash the risk neutral probability of a three four standard deviation decline in the index about 36 percent 46 percent over a year is about 10 100 times more likely than under the assumption of lognormality recently the increasing popularity of derivatives and some highly publicized failures to control risk have led to increased efforts to find reasonable methods to measure the sensitivity of large institutional derivatives portfolios to extreme events merely because such events are rare is not sufficient to ignore them since on the few occasions when they do occur significant amounts of money can change hands potentially wiping out profits accumulated over long prior periods a key assumption behind methods of estimation is the joint probability distribution of constituent underlying asset returns this has long been a concern of financial economists since probability assumptions are critical to much of their research during the last quarter century heretofore probability distributions of stock market returns have typically been estimated from historical time series unfortunately common hypotheses may not capture the probability of extreme events and the events of interest are rare or may not be present in the historical record even though they are clearly possible

why has under 5 mortality decreased at such different rates in different countries controlling for socioeconomic and geographic factors under 5 mortality 5q0 in developing countries has been declining at about 2 7 per year a high rate of technical progress this paper adduces theoretical and empirical reasons for rejecting the usual specification of homogeneous technical progress across countries and uses a panel of 95 developing countries for the period 1970 2000 to explore the consequences of heterogeneity allowing country specific rates of technical progress sharply reduces the estimated income elasticity of 5q0 and points to country variation in technical progress as the principal source of the large cross country variation in 5q0 decline education levels and physician coverage also contribute and are less affected than income of allowing country variation in technical progress the paper concludes by decomposing 1970 2000 5q0 decline into its different sources for each country

the quantity and quality of life and the evolution of world inequality gdp per capita is usually used to proxy for the quality of life of individuals living in different countries welfare is also affected by quantity of life however as represented by longevity this paper incorporates longevity into an overall assessment of the evolution of cross country inequality and shows that it is quantitatively important the absence of reduction in cross country inequality up to the 1990s documented in previous work is in stark contrast to the reduction in inequality after incorporating gains in longevity throughout the post world war ii period health contributed to reduce significantly welfare inequality across countries this paper derives valuation formulas for infra marginal changes in longevity and computes a full growth rate that incorporates the gains in health experienced by 96 countries for the period between 1960 and 2000 incorporating longevity gains changes traditional results countries starting with lower income tended to grow faster than countries starting with higher income we estimate an average yearly growth in full income of 4 1 percent for the poorest 50 percent of countries in 1960 of which 1 7 percentage points are due to health as opposed to a growth of 2 6 percent for the richest 50 percent of countries of which only 0 4 percentage points are due to health additionally we decompose changes in life expectancy into changes attributable to 13 broad groups of causes of death and three age groups we show that mortality from infectious respiratory and digestive diseases congenital perinatal and ill defined conditions mostly concentrated before age 20 and between ages 20 and 50 is responsible for most of the reduction in life expectancy inequality at the same time the recent effect of aids together with reductions in mortality after age 50 due to nervous system senses organs heart and circulatory diseases contributed to increase health inequality across countries

economic growth population theory and physiology the bearing of long term processes on the this lecture sketches a theory of the secular decline in morbidity and mortality that takes account of changes induced in physiological functioning since 1700 the synergism between technological and physiological improvements has produced a form of human evolution biological though not genetic rapid culturally transmitted and not necessarily stable which is still ongoing in both oecd and developing countries thermodynamic and physiological aspects of economic growth are defined and their impact on growth rates is assessed implications of this theory for population forecasting measurement of national income demand for leisure pension policies and demand for health care are considered excerpt

the effect of pensions on longevity evidence from union army veterans this study uses changes in pension laws for union army veterans as a natural experiment to estimate the causal effect of pensions on longevity and to examine potential pathways underlying such a relationship we examine the effects of the pension laws of 1907 and 1912 which granted old age pensions to union army veterans life expectancy for veterans who received such a pension increased by 0 5 years and 2 7 years respectively the effect of veteran pensions on longevity was large across wealth groups and size of city pensions reduced mortality for both acute and non acute causes of death

the economic lives of the poor in what turned out to be a rhetorical master move the 1990 world development report from the world bank defined the extremely poor people of the world as those who are currently living on no more than 1 per day per person measured at the 1985 purchasing power parity ppp exchange rate in 1993 the poverty line was updated to 1 08 per person per day at the 1993 ppp exchange rate which is the line we use in this paper poverty lines have always existed indeed 1 per day was chosen in part because of its proximity to the poverty lines used by many poor countries 1 however the 1 a day poverty line has come to dominate the conversations about poverty to a remarkable extent

do dropouts drop out too soon wealth health and happiness from compulsory schooling abstract this paper uses compulsory schooling laws to evaluate high school dropout decisions the main empirical result is that lifetime wealth increases by about 15 with an extra year of compulsory schooling students compelled to stay in school are also less likely to report being in poor health unemployed and unhappy the main conclusion is that high school aversion alone is unlikely to explain why dropouts forgo substantial gains to lifetime wealth the results are more consistent with the possibility that adolescents ignore or heavily discount future consequences when deciding to drop out of school if teenagers are myopic making school compulsory or offering incentives to stay in school may help improve lifetime outcomes

can the west save africa in the new millennium the western aid effort toward africa has surged due to writ ings by well known economists a celebrity mass advocacy campaign and decisions by western leaders to make africa a major foreign policy priority this survey contrasts the predominant transformational approach west comprehensively saves africa to occasional swings to a marginal approach west takes one small step at a time to help individual africans evaluation of one step at a time initiatives is generally easier than that of transformational ones either through controlled experiments although these have been oversold or simple case studies where it is easier to attribute outcomes to actions we see two themes emerge from the literature survey 1 escalation as each successive western transformational effort has yielded disappointing results as judged at least by stylized facts since again the econometrics are shaky the response has been to try an even more ambitious effort and 2 the cycle of ideas rather than a progressive testing and discarding of failed ideas we see a cycle in aid ideas in many areas in africa with ideas going out of fashion only to come back again later after some lapse long enough to forget the previous disappointing experience both escalation and cyclicality of ideas are symptomatic of the lack of learning that seems to be characteristic of the transfor mational approach in contrast the marginal approach has had some successes in improving the well being of individual africans such as the dramatic fall in mortality

public private mix of health expenditure a political economy and quantitative analysis this paper constructs a simple model to examine decisions on public and private health spending under majority voting in the model agents with heterogeneous incomes choose how much to consume and spend on health care and vote for public health expenditure the health status of an agent is determined by a ces composite of public and private health expenditure the existence and uniqueness of the voting equilibrium are established a quantitative exercise reveals the importance of the relative effectiveness of public and private health expenditure and their substitutability in determining the public private mix of health expenditure and in accounting for the observed differences across a sample of 22 advanced democratic countries

the strength of issues using multiple measures to gauge preference stability ideological constraint and issue voting a venerable supposition of american survey research is that the vast majority of voters have incoherent and unstable preferences about political issues which in turn have little impact on vote choice we demonstrate that these findings are manifestations of measurement error associated with individual survey items first we show that averaging a large number of survey items on the same broadly defined issue area for example government involvement in the economy or moral issues eliminates a large amount of measurement error and reveals issue preferences that are well structured and stable this stability increases steadily as the number of survey items increases and can approach that of party identification second we show that once measurement error has been reduced through the use of multiple measures issue preferences have much greater explanatory power in models of presidential vote choice again approaching that of party identification

health insurance and income inequality health insurance and other in kind forms of compensation and government benefits are typically not included in measures of income and analyses of inequality this omission is important given the large and growing cost of health care in the united states and the presence of large government health insurance programs such as medicaid and medicare it is crucial to understand how health insurance and related public policies contribute to measured economic well being and inequality our paper assesses the effect on inequality of the primary government programs that affect health insurance

income and population growth do populations grow as countries become richer in this study we estimate the effects on population growth of shocks to national income that are plausibly exogenous and unlikely to be driven by technological change for a panel of over 139 countries spanning the period 1960 2007 we interact changes in international oil prices with countries average net export shares of oil in gdp controlling for country and time fixed effects we find that this measure of oil price induced income growth is positively associated with population growth the iv estimates indicate that a 1 percentage point increase in gdp per capita growth over a 10 year period increases countries population growth by around 0 1 percentage points furthermore we find that this population effect results from both a positive effect on fertility and a negative effect on infant and child mortality

health status and portfolio choice causality or heterogeneity abstract this paper explores the role of unobserved individual characteristics in the health assets and health portfolio correlations we apply various econometrics models to a unique longitudinal dataset with rich information that allows for the exploitation of four different health indices our findings show strong cross sectional correlations between health and both financial and non financial assets but these correlations seem to be mainly driven by heterogeneity as the correlations largely disappear in the fixed effects model adverse health shocks however are found to motivate a safer portfolio choice even after individual fixed effects are controlled for a result consistent with the prediction made by the background risk theory our findings suggest that health shocks shift investment from risky assets toward other financial assets but keep the total financial assets unchanged

stochastic risk premiums stochastic skewness in currency options and stochastic discount factors in international economies abstract we develop models of stochastic discount factors in international economies that produce stochastic risk premiums and stochastic skewness in currency options we estimate the models using time series returns and option prices on three currency pairs that form a triangular relation estimation shows that the average risk premium in japan is larger than that in the us or the uk the global risk premium is more persistent and volatile than the country specific risk premiums and investors respond differently to different shocks we also identify high frequency jumps in each economy but find that only downside jumps are priced finally our analysis shows that the risk premiums are economically compatible with movements in stock and bond market fundamentals

an economic approach to the study of the relationship between housing hazards and health the case of residential fuel poverty in france abstract the impact of housing hazards on health outcomes is becoming a major issue especially given the recent and on going reviews of energy legislation in many european countries a large body of epidemiological literature argues that fuel poverty a frequently debated example of a housing hazard involving low indoor temperatures is associated with heightened health risks by using a large scale nationally representative dataset i seek in this article to delve into this alleged association and uncover a causal relationship between fuel poverty and self assessed health coming from an economics standpoint i used a panel approach based on an instrumental fixed effects model which allow me to analyse causality i used both objective and subjective fuel poverty indicators the results show that there is a significant causal relationship between fuel poverty and self assessed health status the estimated causality is exacerbated when subjective fuel poverty indicators are used the results also show that the negative impact of fuel poverty on health is deferred meaning that fuel poverty takes time to manifest itself in terms of poor health in policy terms this study adds to the debate on investing in housing energy efficiency schemes to reduce fuel poverty and thereby improve health outcomes it also lends support to the argument according to which improving housing conditions to curb fuel poverty is a lever for reducing pubic expenditures on health care

good for living on the relationship between globalization and life expectancy this paper analyzes the relationship between three dimensions economic social and political of globalization and life expectancy using a panel of 92 countries covering the 1970 2005 period using different estimation techniques and sample groupings we find that economic globalization has a robust positive effect on life expectancy even when controlling for income nutritional intake literacy number of physicians and several other factors the result also holds when the sample is restricted to low income countries only in contrast political and social globalization have no such robust effects

pharmaceuticals and the developing world pharmaceuticals have greatly improved health in developing countries but many people in developing countries do not obtain even inexpensive pharmaceuticals and little pharmaceutical r d is oriented toward products needed by developing countries such as a malaria vaccine access to existing products could be improved by facilitating differential pricing for example by subsidizing donation programs and reforming health care delivery r d incentives could be improved if rich countries or international organization committed to purchase needed products when they are developed and make them available to the poor

environment health and human capital in this review we discuss three major contributions economists have made to our understanding of the relationship between the environment and individual well being first in explicitly recognizing how optimizing behavior particularly in the form of residential sorting can lead to nonrandom assignment of pollution economists have employed a wide range of quasi experimental techniques to develop causal estimates of the effect of pollution second economic research has placed a considerable focus on the role of avoidance behavior which is an important component for understanding the difference between biological and behavioral effects of pollution and for proper welfare calculations lastly economic research has expanded the focus of analysis beyond traditional health outcomes to include measures of human capital including labor supply productivity and cognition our review of the quasi experimental evidence on this topic suggests that pollution does indeed have a wide range of effects on individual well being even at levels well below current regulatory standards given the importance of health and human capital as an engine for economic growth these findings underscore the role of environmental conditions as an important factor of production jel i12 i31 j24 q51 q53

the effect of education on adult mortality and health evidence from britain there is a strong positive and well documented correlation between education and health outcomes in this paper we attempt to understand to what extent this relationship is causal our approach exploits two changes to british compulsory schooling laws that generated sharp across cohort differences in educational attainment using regression discontinuity methods we find the reforms did not affect health although the reforms impacted educational attainment and wages our results suggest caution as to the likely health returns to educational interventions focused on increasing educational attainment among those at risk of dropping out of high school a target of recent health policy efforts jel h52 i12 i21 i28

safety first consumption abstract this paper develops a model of safety first consumption behavior in which the likelihood of survival to the next period depends on current consumption levels below a threshold asset level individuals follow a decumulation path and above that level they follow an accumulation path saving rates then vary discontinuously with asset level generating a poverty trap and divergence in incomes an increase in the likelihood of surviving raises aggregate saving a more equitable distribution of assets can be consistent with greater aggregate savings and growth because of declining marginal propensity to save over some asset intervals

wealthier is healthier we estimate the effect of income on health using cross country timeseries data on health infant and child mortality and life expectancy and income per capita we use instrumental variables estimates using exogenous determinants of income growth to identify the pure income effect on health isolated from reverse causation or incidental association the long run income elasticity of infant and child mortality in developing countries lies between 0 2 and 0 4 using these estimates we calculate that over a half a million child deaths in the developing world in 1990 alone can be attributed to the poor economic performance in the 1980s

u s stock market crash risk 1926 2010 abstract this paper examines how well alternate time changed levy processes capture stochastic volatility and the substantial outliers observed in u s stock market returns over the past 85 years the autocorrelation of daily stock market returns varies substantially over time necessitating an additional state variable when analyzing historical data i estimate various one and two factor stochastic volatility levy models with time varying autocorrelation via extensions of the bates 2006 methodology that provide filtered daily estimates of volatility and autocorrelation the paper explores option pricing implications including for the volatility index vix during the recent financial crisis

the mortality effects of retirement evidence from social security eligibility at age 62 abstract social security eligibility begins at age 62 and approximately one third of americans immediately claim at that age we examine whether age 62 is associated with a discontinuous change in aggregate mortality a key measure of population health using mortality data that covers the entire u s population and includes exact dates of birth and death we document a robust two percent increase in male mortality immediately after age 62 the change in female mortality is smaller and imprecisely estimated additional analysis suggests that the increase in male mortality is connected to retirement from the labor force and associated lifestyle changes

is democracy good for the poor many scholars claim that democracy improves the welfare of the poor this article uses data on infant and child mortality to challenge this claim cross national studies tend to exclude from their samples nondemocratic states that have performed well this leads to the mistaken inference that nondemocracies have worse records than democracies once these and other flaws are corrected democracy has little or no effect on infant and child mortality rates democracies spend more money on education and health than nondemocracies but these benefits seem to accrue to middle and upper income groups

the impact of the great migration on mortality of african americans evidence from the deep south the great migration the massive migration of african americans out of the rural south to largely urban locations in the north midwest and west was a landmark event in u s our paper shows that this migration increased mortality of african americans born in the early twentieth century south this inference comes from an analysis that uses proximity of birthplace to railroad lines as an instrument for migration

healthy bodies and thick wallets the dual relation between health and economic status there is abundant evidence of a quantitatively large association between many measures of economic status including income and wealth and a variety of health outcomes such as mortality or morbidity however considerable and often heated debate remains especially across disciplines about the direction of causation and about why the association arises although medical scientists are often convinced that the dominant if not exclusive pathway is that variation in socioeconomic status produces health disparities they are increasingly debating among themselves about why low economic status might lead to poor health at least for modern industrial countries 1 the old standby arguments the less well to do have access to less or lower quality medical care or a stronger pattern of deleterious personal behaviors have been rejected as insufficient instead a series of intriguing competing theories have arisen that emphasize long term impacts of early childhood or even inter uterine environmental factors the cumulative effects of prolonged exposures to individual stressful events or reactions to macro societal factors such as rising levels of income inequality a common link is that each theory attempts to document the physiological processes through which low economic status leads to poorer health while these scientific questions are extremely important this research has taken place with little input from economists economists are now making contributions about the alternative pathway the impact poor health may have on economic resources poor health may restrict a family s capacity to earn income or to accumulate assets by limiting work or by raising medical expenses at a minimum this work should provide a caution against exaggerating the magnitude of causation from economic status to health outcomes but the potential contribution runs deeper as people age the evolving variation in individual health outcomes may offer additional statistical information to estimate parameters of household savings and consumption behavior that so far have proven to be somewhat elusive thus incorporating health uncertainty and risk into economic models should eventually enrich our understanding of basic tenets of household behavior the first section of this paper documents the size of the association between health and one prominent economic status measure household wealth section two deals with how health influences economic status by sketching out reasons why health may alter household savings and eventually wealth and then providing estimates of the empirical magnitude of these effects section three shifts attention to the alternative pathway the links between economic status and health and summarizes 2major controversies and evidence surrounding these issues

humanitarian aid fertility and economic growth this paper examines the effect of humanitarian aid on fertility and economic growth in an overlapping generations model where health status in adulthood depends on health in childhood adult agents allocate their time to work leisure and childrearing activities humanitarian aid influences the probability of survival to adulthood health in childhood and the time that adults allocate to childrearing giving rise to an ambiguous effect on both fertility and growth an empirical investigation for the period 1973 2007 suggests that humanitarian aid has on average a zero effect on the rates of fertility and of per capita output growth

biological measures of the standard of living when economists investigate long term trends and socioeconomic differences in the standard of living or quality of life they have traditionally focused on monetary measures such as gross domestic product which has occupied center stage for over 50 years in recent decades however scholars have increasingly recognized the limitations of monetary measures while seeking useful alternatives this essay examines the unique and valuable contributions of four biological measures life expectancy morbidity stature and certain features of skeletal remains to understand levels and changes in human well being people desire far more than material goods and in fact they are quite willing to trade or give up material things in return for better physical or psychological health for most people health is so important to their quality of life that it is useful to refer to the biological standard of living biological measures may be especially valuable for historical studies and for other research circumstances where monetary measures are thin or lacking a concluding section ruminates on the future evolution of biological approaches in measuring happiness

wealth health and health services in rural rajasthan what are the determinants of health and of well being income and wealth are clearly part of the story but does access to health care have a large independent effect as the advocates of more investment in health care such as the world health organization s commission on macroeconomics and health commission on macroeconomics and health 2001 have argued this paper reports on a recent survey in a poor rural area of the state of rajasthan in india intended to shed some light on this issue where there was an attempt to use a set of interlocking surveys to collect data on health and economic status as well as the public and private provision of health care

testing for asymmetric information in the viager market a viager real estate transaction consists in selling a property in return for a down payment and a rent life annuity that the buyer has to pay until the seller dies this paper tests for the presence of asymmetric information in this market thanks to a no arbitrage condition buyers must be indierent between purchasing on the standard and viager market we identify the type of the seller as a sum of weighted death probabilities by comparing these sums with analogously defined national level sums we can check whether viager sellers have the same survival distribution as individuals in the population we then develop a model for a viager sale and derive testable predictions under symmetric and asymmetric information our test for asymmetric information consists in regressing the contract parameters down payment and rent on the inferred type of the seller and comparing the estimates with the predicted outcomes notarial data are used on transactions in paris between 1992 and 2001 we test and accept that our no arbitrage condition is empirically satisfied we find that sellers do not have the same survival distributions as comparable persons in the population and hence they have information about their death probabilities the hypothesis that information is symmetrically distributed between buyers and sellers is accepted this highlights that the information about the seller s survival prospects is no longer private when the contract is signed

intergenerational persistence in health in developing countries the penalty of gender inequality this paper is motivated to investigate the often neglected payoff to investments in the health of girls and women in terms of next generation outcomes this paper investigates the intergenerational persistence of health across time and region as well as across the distribution of maternal health it uses comparable microdata on as many as 2 24 million children born of about 0 6 million mothers in 38 developing countries in the 31 year period 1970 2000 mother s health is indicated by her height bmi and anemia status child health is indicated by mortality risk and anthropometric failure we find a positive relationship between maternal and child health across indicators and highlight non linearities in these relationships the results suggest that both contemporary and childhood health of the mother matter and that the benefits to the next generation are likely to be persistent averaging across the sample persistence shows a considerable decline over time disaggregation shows that the decline is only significant in latin america persistence has remained largely constant in asia and has risen in africa the paper provides the first cross country estimates of the intergenerational persistence in health and the first estimates of trends
