aging and inequality in income and health in our earlier work we used data from the national health interview survey nhis to examine life cycle patterns in health status and in the joint distribution of health status and income deaton and paxson 1998 in this paper we summarize and extend those results and provide new evidence from the panel study of income dynamics psid both surveys contain a measure of household income and collect information on an ordinal measures of self reported health status srhs that ranges from 1 excellent to 5 poor section i concerns problems related to the measurement of inequality in health section ii presents evidence from the two surveys on health and income inequality this abstract was borrowed from another version of this item

learning and wage dynamics we develop a dynamic model of learning about worker ability in a competitive labor market the model produces three testable implications regarding wage dynamics 1 although the role of schooling in the labor market s inference process declines as performance observations accumulate the estimated effect of schooling on the level of wages is independent of labor market experience 2 timeinvariant variables correlated with ability but unobserved by employers such as certain test scores are increasingly correlated with wages as experience increases and 3 wage residuals are a martingale we present evidence from the nlsy that is broadly consistent with the model s predictions

a theory of socio economic disparities in health over the life cycle motivated by the observation that medical care explains only a relatively small part of the ses health gradient we present a life cycle model that incorporates several additional behaviours that potentially explain jointly a large part of observed disparities as a result the model provides not only a conceptual framework for the ses health gradient but more generally an improved framework for the production of health we derive novel predictions from the theory by performing comparative dynamic analyses more generally our comparative dynamic method can be applied to models of similar form e g human capital health deficits firm investment to name a few

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

intrinsic motivation in public service theory and evidence from state supreme courts abstractthis paper provides a theoretical and empirical analysis of the intrinsic preferences of state appellate court judges we construct a panel data set using published decisions from all state supreme courts from 1947 to 1994 we estimate the effects of changes in judges employment conditions on a number of measures of judicial performance the results are consistent with the hypothesis that judges are intrinsically motivated to provide high quality decisions and that at the margin they prefer quality over quantity when judges face less time pressure whether from the introduction of an intermediate appellate court the weakening of electoral demands or an increased salary they write more well researched opinions that are cited more often by other judges these effects are strongest when judges have more discretion to select their portfolios of cases

the well being of the elderly and wage arrears in russia about one third of households with elderly were not paid their wages during the mid 1990s in russia applying matching estimations to a nationally representative survey the study shows that wage arrears had detrimental effects on the well being of the elderly in these families salaries in households with wage arrears dropped by almost two thirds income fell by more than one third and poverty doubled behavioral responses were only partly effective the net revenue loss amounted to five sixths of the wage shock for men and nine tenths of the wage shock for women the elderly cut back on food expenses by reducing food purchases and adjusting their diet towards cheaper calories economising on expenses equal to around one quarter of the wage reduction caloric and protein intakes dropped although less than income and the nutritional content of food consumption with regard to vitamins and minerals deteriorated wage arrears worsened male health more than female health even though the decline in income was comparable functional limitations rose by 8 for men and 3 for women and self rated health declined by 2 5 for men and 0 5 for women old age men with arrears were almost twice as likely to die before the next survey round and functional limitations of surviving men rose by more than 10 by contrast there was no impact on the next round s health status of old age women a rich data set is used to discount alternative explanations including feedback from health to income other economic factors health service access health behavior and environmental conditions jel i12 i30 j14 j30

family income and child health in the uk recent studies examining the relationship between family income and child health in the uk have produced mixed findings we re examine the income gradient in child general health and its evolution with child age in this country using a very large sample of british children we find that there is no correlation between income and child general health at ages 0 1 that the gradient emerges around age 2 and is constant from age 2 to age 17 in addition we show that the gradient remains large and significant when we reduce the endogeneity of income furthermore our results indicate that the gradient in general health reflects a greater prevalence of chronic conditions among low income children and a greater severity of these conditions taken together these findings suggest that income does matter for child health in the uk and may play a role in the intergenerational transmission of socioeconomic status

the causal effect of family income on child health in the uk recent studies examining the effect of family income on child health have been unable to account for the endogeneity of income using data from a british cohort study we address this gap by exploiting exogenous variation in local labour market characteristics to instrument for family income we estimate the causal effect of family income on different measures of child health and explore the role of potential transmission mechanisms we find that income has a very small but significant causal effect on subjective child health and no significant effect on chronic health conditions apart from respiratory illnesses using the panel structure we show that the timing of income does not matter for young children moreover our results provide further evidence that parental health does not drive a spurious relationship between family income and child health our study implies that financial transfers are unlikely to deliver substantial improvements in child health

direct and indirect effect of depression in adolescence on adult wages it is well recognized that a depressive mental state can persist for a long time and this can adversely impact labour market outcomes the aim of this article is to examine the direct association between depression status in late teenage years and adult wages as well as the indirect association operating through accumulated education experience and occupation choice using the national longitudinal survey of youth 1997 data we find adolescent depression is associated with a wage penalty of around 10 15 but its mechanics are very different for males and females for males about three quarters of the wage penalty is through the direct channel whilst for females the indirect effect channel is dominant the indirect channel is driven by lower accumulated education mostly because depression discourages further study post high school these results are important because they imply that the association between adolescent depression and wages is stronger than has been estimated in previous cross section

does raising family income cause better child health evidence from china abstractfew studies have attempted to identify a causal link between family income and child health especially in developing countries this article takes advantage of an exogenous income shock created by china s rural tax reform between 2000 and 2003 to study the causal impact of household income on child health the analysis finds that an increase in family income significantly raises children s height for age z scores these effects are robust to alternative specifications and a comprehensive set of controls the article also investigates possible mechanisms generating this result we find that with a higher income level better nutritional intake partially accounts for the improvement in child health

dynamics of fine wine and asset prices evidence from short and long run co movements this article examines short and long term price linkages among the majority of fine wine and equity markets over the period of 2003 to 2012 we do not consider the price index liv ex 100 or 500 as is typically undertaken in previous studies but rather examine the auction price series of the world s most traded wine vintage pairs 5 bordeaux first growth 8 bordeaux second growth 5 burgundy 3 rhone 4 italian 5 californian 1 australian and 1 portuguese a global equity index is also included using the morgan stanley capital international world cointegration procedures the granger non causality test and ecm are used to analyse short and long run relationships among these markets the results indicate a strong effect of financial markets on wine prices and short term causality for certain wines moreover the findings indicate short run causality between the wines themselves revealing a leader exogenous or follower endogenous status of certain fine wines in price dynamics and also long ru

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

contracting in the shadow of the law economic models of contract typically assume that courts enforce obligations based on verifiable events corresponding to the legal rule of specific performance as a matter of law this is not the case this leaves open the question of optimal contract design given the available remedies used by the courts this article shows that american standard form construction contracts can be viewed as an efficient mechanism for implementing building projects given existing legal rules it is shown that a central feature of these contracts is the inclusion of governance covenants that shape the scope of authority and regulate the ex post bargaining power of parties our model also implies that the legal remedies of mistake impossibility and the doctrine limiting damages for unforeseen events developed in the case of hadley v baxendale are efficient solutions to the problem of implementing complex exchange

mortality inequality the good news from a county level approach in this essay we ask whether the distributions of life expectancy and mortality have become generally more unequal as many seem to believe and we report some good news focusing on groups of counties ranked by their poverty rates we show that gains in life expectancy at birth have actually been relatively equally distributed between rich and poor areas analysts who have concluded that inequality in life expectancy is increasing have generally focused on life expectancy at age 40 to 50 this observation suggests that it is important to examine trends in mortality for younger and older ages separately turning to an analysis of age specific mortality rates we show that among adults age 50 and over mortality has declined more quickly in richer areas than in poorer ones resulting in increased inequality in mortality this finding is consistent with previous research on the subject however among children mortality has been falling more quickly in poorer areas with the result that inequality in mortality has fallen substantially over time we also show that there have been stunning declines in mortality rates for african americans between 1990 and 2010 especially for black men finally we offer some hypotheses about causes for the results we see including a discussion of differential smoking patterns by age and socioeconomic status

patenting in the shadow of competitors this article empirically examines the patenting behavior of new biotechnology firms that have different litigation costs i show that firms with high litigation costs are less likely to patent in subclasses with many other awards particularly those of firms with low litigation costs this pattern is consistent with the literature on costly litigation which suggests that firms that have high litigation costs will take greater precautions to avoid litigation these results are robust to a variety of control variables and modifications that seek to test alternative explanations

the causal effect of income on health evidence from german reunification we investigate whether there was a causal effect of income changes on the health satisfaction of east and west germans in the years following reunification our data source is the german socio economic panel gsoep between 1984 and 2002 and we fit a recently proposed fixed effects ordinal estimator to our health measures and use a causal decomposition technique to account for panel attrition we find evidence of a significant positive effect of income changes on health satisfaction but the quantitative size of this effect is small this is the case with respect to current income and a measure of permanent income

the effect of income on mortality evidence from the social security notch abstract legislation in the 1970s created a notch in social security payments with those born after january 1 1917 receiving sharply lower benefits using restricted use versions of the national mortality detail file combined with census data we use this quasi experiment to examine the income mortality link in an elderly population estimates from difference in difference and regression discontinuity models show the higher income group has a statistically significantly higher mortality rate contradicting the previous literature we also found that younger cohorts responded to lower incomes by increasing postretirement work effort suggesting that moderate employment has beneficial health effects for the elderly

the resolution of financial distress most models of financial structure embody an assumption about financial distress that causes debt to be costly to the issuing firm this approach has been criticized on the grounds that the assumed costs could be avoided by a costless financial reorganization in this article we show that despite the possibility of costless reorganization it may be rational for firms to incur significant costs in the resolution of financial distress the main assumptions that give rise to our results are the existence of asymmetric courts to impose a reorganization on the claimants of a firm article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

can markets stimulate rights on the alienability of legal claims the alienability of legal claims holds the promise of increasing access to justice and fostering development of law i develop a principal agent framework where litigation funders provide expertise in reducing uncertainty in agents disutility of production the model leads to the counterintuitive prediction that litigation funders prefer cases with novel issues and social surplus is positively correlated with legal uncertainty consistent with the model court backlog court expenditures and a slowing in average time to completion are associated with third party funding cases with third party funding receive more citations and are reversed less often than comparable cases without such arrangements

the long term impact of military service on health evidence from world war ii and korean war veterans during the world war ii and korean war era the u s military freely distributed cigarettes to overseas personnel and provided low cost tobacco products on domestic military bases in fact even today the military continues to sell subsidized tobacco products on its bases using a variety of instrumental variables approaches to deal with nonrandom selection into the military and into smoking we provide substantial evidence that cohorts with higher military participation rates subsequently suffered more premature mortality more importantly we show that a large fraction 35 to 79 percent of the excess veteran deaths due to heart disease and lung cancer are attributable to military induced smoking

the role of child health and economic status in educational health and labour market outcomes in young adulthood the ontario child health study provides the first opportunity in canada to assess directly the relationship between socio economic and health status in childhood and levels of completed schooling health status and labour market success in young adult hood we find that childhood health problems are negatively associated with educational attainment especially the probability of a university degree and the health status of young adults our results also imply that childhood health problems influence adult labour force outcomes especially for males mainly through adult levels of schooling and health jel classification 110

estimating the effect of income on health and mortality using lottery prizes as an exogenous source of variation in income a vast literature has established a strong positive relation between income and health status and a negative relation with mortality this paper studies the effects of income on health and mortality using only the part of income variation due to a truly exogenous factor monetary lottery prizes of individuals the findings are that higher income causally generates good health and that this effect is of a similar magnitude as when traditional estimation techniques are used a 10 percent income increase improves health by about 4 5 percent of a standard deviation

rising mortality and life expectancy differentials by lifetime earnings in the united states are mortality and life expectancy differences by socioeconomic groups increasing in the united states using a unique data set matching administrative and survey data this study explores trends in these differentials by lifetime earnings for the 1983 2003 period results indicate a consistent increase in mortality differentials across sex and age groups the study also finds a substantial increase in life expectancy differentials by lifetime earnings the top to bottom quintile premium increased 30 percent for men and almost doubled for women these results complement recent research to point to almost five decades of increasing differential mortality in the united states

the relationship between economic status and child health evidence from the united states the positive relationship between socioeconomic status ses and health e g mortality and morbidity often called the gradient is well known in the social sciences an issue of contro versy about this relationship is the direction of causality does ses affect health or health affect ses anne case darren lubotsky and christina paxson 2002 examined the effect of income on the health status of children since children in developed countries are unlikely to work the relationship between income and health status is unidirectional from income to health status not only do case lubotsky and paxson hereafter clp find a positive relationship between health and income but they also find that the income gradient becomes steeper as children age the steepening gradient implies the negative effects of low family incomes on children s health become larger as a child ages with the harmful effects of low income on a child s health likely to accumulate over the child s lifetime janet currie and mark stabile 2003 highlight two limitations associated with using crosssection data as were used by clp when trying to explain the possible mechanisms underlying the relationship between ses and health first children from low ses households may be less able to recover from a particular health shock and as a result the negative effects of each shock are likely to accumulate over time second low ses children may respond to a particular shock in the same way as high ses children but are subjected to more health shocks as they age identifying which of these two mechanisms is dominant is critical for policy under the first mechanism policy would be directed at improving the access to and or quality of medical care for low ses children so they are able to respond to shocks in the same way as high ses children on the other hand if the second mechanism is dominant and low ses children respond to health shocks in the same way as high ses children social funds should be directed toward programs that reduce the arrival rate of new health shocks using data from a panel of canadian children for the period 1994 to 1998 currie and stabile cs found that given a chronic condition in 1994 low ses children were no more likely than high ses children to be in poor health in 1998 the lack of an ses differential response to a given shock after four years suggests the first mechanism above is not the cause of the increasing strength of the gradient as canadian children get older an important finding by cs is that lowses canadian children are subject to more shocks as they age thereby suggesting the impor tance of the second explanation of the strengthening of the ses health relationship 1

the dynamics of health in the british household panel survey this paper considers the dynamics of a categorical indicator of self assessed health using eight waves 1991 1998 of the british household panel survey bhps our analysis has three focal points the relative contributions of state dependence and heterogeneity in explaining the dynamics of health the existence and consequences of health related sample attrition and the investigation of the effects of measures of socioeconomic status with a particular focus on educational attainment and income to investigate these issues we use dynamic panel ordered probit models there is clear evidence of health related attrition in the data but this does not distort the estimates of state dependence and of the socioeconomic gradient in health the models show strong positive state dependence and heterogeneity accounts for around 30 of the unexplained variation in health copyright 2004 john wiley sons ltd

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

health and wealth of elderly couples causality tests using dynamic panel data models a positive relationship between socio economic status ses and health the health wealth gradient is repeatedly found in many industrialized countries this study analyzes competing explanations for this gradient causal effects from health to wealth health causation and causal effects from wealth to health wealth or social causation using six biennial waves of couples aged 51 61 in 1992 from the us health and retirement study we test for causality in panel data models incorporating unobserved heterogeneity and a lag structure supported by specification tests in contrast to tests relying on models with only first order lags or without unobserved heterogeneity these tests provide no evidence of causal wealth health effects on the other hand we find strong evidence of causal effects from both spouses health on household wealth we also find an effect of the husband s health on the wife s mental health but no other effects from one spouse s health to health of the other spouse

socio economic inequality in ill health amongst the elderly should one use current or permanent income in belgium income related inequality in ill health among the 65 is present but reduces significantly as soon as one restricts the analysis to the 65 the main goal of this paper is to check whether these findings based on current income are robust to the income concept used the analysis is repeated using estimates of permanent income measured inequality among the 65 remains very limited suggesting that the observed findings are not heavily dependent upon the income concept finally i suggest an explanation for the observed difference in inequality between the 65 and the 65 i argue that this difference is likely to be correlated with differences across income groups of 1 sample attrition and 2 mortality

the rise of obesity in europe an economic perspective obesity in europe is rising this paper investigates the economic rationales for public intervention to control obesity we present new empirical evidence showing that family background is related to obesity among young european adults this evidence provides a strong basis for intervention on equity grounds particularly targeted towards children the case for intervention on efficiency grounds is less clear cut and in most cases the evidence is relatively weak we find insufficient evidence that information deficiencies are important as the majority of europeans appear to be aware of the bad consequences of obesity on health we also find that the potential health insurance externality non obese effectively subsidizing obese individuals is small in support of policy intervention we show that there are product and labour market imperfections obese employees earn less than the non obese we also find that there is a remarkably high proportion of individuals with self control problems who fail to stick to their self declared weight related plans regulations that affect fast food advertisements and the location and access to fast food vending machines and establishments may help these individuals in controlling their weight giorgio brunello pierre carl michaud and anna sanz de galdeano

heterogeneity and fine wine prices application of the quantile regression approach this study addresses the price heterogeneity of the five first growths of bordeaux we apply the quantile regression qr approach with market segmentation based on wine bottle price quantiles we

the economics of collective reputation evidence from the wine industry we use original data regarding the array of italian winery coalitions wine denominations to analyze the economics and determinants of collective reputation we first run a cross sectional analysis with 2008 data and the full set of control variables then move to the dynamics of collective reputation with panel data analysis on a 30 year time span 1978 2008 group reputation is history dependent in particular past bad collective behavior increases the probability of being stuck in a bad reputation trap minimum quality standards and effective enforcement are fundamental drivers of group reputation the relationship between group size and collective reputation is non linear free entry may not be optimal due to free riding problems finally institutional signals such as the wine classification system are useful because they can be used by consumers as easily available proxies for information that is much more difficult to acquire

an empirical test of the comparative and contributory negligence rules in accident law scholars in the field of law and economics have developed an extensive theoretical literature on the effects of liability rules in accident law but have done little testing of their theoretical models in this article i develop an empirically testable model of the incentives for injurers and victims to avoid accidents under both the older contributory negligence rule and the newer rule of comparative negligence the model takes account of the fact that in the automobile accident context drivers do not know in advance with whom they will be involved in an accident and whether they will be the injurer or the victim or both it also allows for uncertainty in legal decision making the model is tested using a data set of rear end automobile accidents litigated in court the results suggest first that incentives to take care to avoid accidents are stronger under the contributory negligence rule than under the newer rule of comparative negligence and second the incentives set up by the comparative negligence rule for drivers to avoid accidents are weaker than is economically efficient

the evolution of common law we present a model of lawmaking by appellate courts in which judges influenced by policy preferences can distinguish precedents at some cost we find a cost and a benefit of diversity of judicial views policy motivated judges distort the law away from efficiency but diversity of judicial views also fosters legal evolution and increases the law s precision we call our central finding the cardozo theorem even when judges are motivated by personal agendas legal evolution is on average beneficial because it washes out judicial biases and renders the law more precise our paper provides a theoretical foundation for the evolutionary adaptability of common law

socioeconomic status and child health why is the relationship stronger for older children case lubotsky and paxson 2001 show that the well known relationship between socio economic status ses and health exists in childhood and grows more pronounced with age however in cross sectional data it is difficult to distinguish between two possible explanations the first is that low ses children are less able to respond to a given health shock the second is that low ses children experience more shocks we show using panel data on canadian children that 1 the gradient we estimate in the cross section is very similar to that estimated previously using u s children 2 both high and low ses children recover from past health shocks to about the same degree and 3 that the relationship between ses and health grows stronger over time mainly because low ses children receive more negative health shocks in addition we examine the effect of health shocks on math and reading scores we find that health shocks affect test scores and future health in very similar ways our results suggest that public policy aimed at reducing ses related health differentials in children should focus on reducing the incidence of health shocks as well as on reducing disparities in access to palliative care

immigrants economic assimilation evidence from longitudinal earnings records we examine immigrants earnings trajectories and measure the extent and speed with which they are able to reduce the earnings gap with natives using a dataset that links respondents of the survey

learning while setting precedents a decision maker dm must address a series of problems over time each period a random case arises and the dm must make a yes or no decision which we call a ruling she is uncertain about the correct ruling until she conducts a costly investigation a ruling establishes a precedent which may be costly to violate in the future we compare the dm s incentive to acquire information the evolution of standards and the social welfare under two institutions nonbinding precedent and binding precedent under nonbinding precedent the dm is not required to follow previous rulings but under binding precedent she must follow previous rulings where applicable we find that compared to nonbinding precedent the incentive for information acquisition is stronger under binding precedent in earlier periods when few precedents exist but as more precedents are established over time the incentive for information acquisition becomes weaker under binding precedent even though erroneous rulings may be perpetuated under binding precedent social welfare can be higher because of the more intensive investigation conducted early on

the distributional impact of health financing in europe a review this article summarises extends and updates previous empirical work on the distributional implications of alternative health care financing arrangements in a selection of european countries and the us on the one hand total health care payments are almost proportional to ability to pay in most countries this is predominantly driven by a high reliance on public financing on the other hand private payments out of pocket payments as well as private insurance premiums are highly regressive more extended reliance on private financing may therefore endanger the equitable nature of financing systems in addition private payments put a heavy burden on unfortunate households

hedonic price functions and the measurement of preferences the case of swedish wine consumers abstract a hedonic price function for wine is estimated using swedish data 1989 1991 implicit prices for quality attributes are determined not from a regression of variety price on a vector of quality attributes but rather from a regression of quantity sold adjusted for weeks of availability on price and quality attributes such a reduced form is justified by the assumption that prices and attribute contents can be taken as exogenous to the swedish consumer price elasticity is estimated to be about 1 65 holding quality constant showing that swedish consumers are highly sensitive to price estimates of the implicit valuations of quality attributes are shown to differ greatly from those obtained from the more usual hedonic regression with price as the dependent variable

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

consumer sorting and hedonic valuation of wine attributes exploiting data from a field experiment this article uses a novel experimental approach to measure consumer willingness to pay wtp for wine attributes we invited customers of a local supermarket who had selected a bottle of wine to purchase to participate in a valuation experiment integrating their original wine choice into the experiment each participant evaluated six alternative wines generating a rich set of data on willingness to pay and consumer characteristics the data from the experiment allow us to compare standard shelf price based wine attribute valuation estimates with estimates using wtp data and an increasing amount of information about individual consumers the full model employs individual fixed effects to estimate wtp parameters without bias from consumer sorting or supply side influences our wtp estimates for wine attributes differ markedly from previous attribute value estimates consumers in our sample display clear and stable preferences for wine varieties but less clear preferences for appellations our results suggest caution is needed in using market prices to estimate parameters of the consumer valuation function for product attributes

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

the pricing of experience goods the example of en primeur wine the market for primeur wine in the bordeaux region allows producers to sell wine that is still in barrels as with all experience goods producers send quality signals to uninformed buyers using original data on bordeaux wines we show that the pricing behavior of producers depends to a large extent on their reputation and much less on short term changes in quality as measured by experts grades we also find that the primeur price has an informative role since a 10 increase in primeur price leads to a 3 increase in prices on the market for bottled wine

prices of american pinot noir wines climate craftsmanship critics pinot noir a variety originating from burgundy in france is the most expensive category of table wine produced in north america this article is aimed at analyzing its price determinants and focuses on climate critical scores and variables related to the winemaker the main findings are as follows 1 pinot noir prices are mainly determined by temperature and precipitation general temperature increases are not beneficial in fact the optimal climate is similar to that in burgundy 2 the second most important variable is the winemaker his or her skill and reputation have a significant impact on prices 3 expert knowledge in the form of critical scores has little explanatory value

the role of dispute settlement procedures in international trade agreements although disputes are typically treated as synonymous with concerns about enforcement in economic models of trade agreements in reality most wto disputes seem to concern the interpretation of vague provisions or instances where the agreement is silent and some have suggested that the wto s dispute settlement body dsb could usefully grant exceptions to rigid contractual obligations these activist dsb roles could help complete an incomplete contract but how activist should the dsb be should dsb rulings set precedent we address these questions by characterizing the optimal choice of contract form and dsb mandate under various contracting conditions jel codes d02 d78 d86 f13 k12 k33

litigation liability and incentives for care abstract in this paper potential injurers are subject to a negligence standard and differ in cost of taking care in the event of accident the injurer s degree of care is private information in litigation that follows award of damages for pain and suffering will lead to a general increase in care and hence reduce the likehood of accident a tighter negligence standard will lead some potential injurers to take more care and others to take less adoption of a rule under which the loser at trial must pay the litigation costs of the winner will reduce the pressure for punitive damages

accidental bequests a curse for the rich and a boon for the poor when accidental bequests signal otherwise unobservable individual characteristics such as productivity and longevity the population should be partitioned into two groups those who do not receive an inheritance and those who do the first tagged group receives a mirrlees second best tax schedule the second group when its type is fully revealed faces a first best tax schedule receiving an inheritance makes high ability types worse off and low ability types better off high ability individuals face a bequest tax of more than 100 percent while low ability types face a bequest tax that can be smaller as well as larger than 100 percent and it might even be negative

legal realism for economists abstract economists have made great progress in understanding the incentives and behavior of actors who operate outside of traditional economic markets including voters legislators and bureaucrats the incentives and behavior of judges however remain largely opaque do judges act as neutral third party enforcers of substantive decisions made by others are judges ordinary policymakers who advance whatever outcomes they favor without any special consideration for law as such emerging recent scholarship has started to explore more nuanced conceptions of how law facts and judicial preferences may interact to influence judicial decisions this work develops a perspective on judging that can usefully be understood as the modern manifestation of american legal realism a jurisprudential movement of lawyers judges and law professors that flourished in the early twentieth century the purpose of this essay is to introduce in simplified form the realist account of judicial decision making to contras

the impact of income shocks on health evidence from cohort data we study the eect of permanent income innovations on health for a prime aged population using information on more than half a million individuals sampled over a twenty five year period in three dierent cross sectional surveys we aggregate data by date of birth cohort to construct a synthetic cohort dataset with details of income expenditure socio demographic factors health outcomes and selected risk factors we then exploit structural and arguably exogenous changes in cohort incomes over the eighties and nineties to uncover causal eects of permanent income shocks on health we find that such income innovations have little eects on health but do aect health behaviour and mortality

why has regional income convergence in the u s declined the past thirty years have seen a dramatic decrease in the rate of income convergence across states and in population flows to wealthy places these changes coincide with 1 an increase in housing prices in productive areas 2 a divergence in the skill specific real returns to living in productive places 3 a redirection of low skilled migration and 4 diminished human capital convergence due to migration we develop a model where falling housing supply elasticity and endogenous labor mobility generates these patterns using a new panel measure of housing supply regulations we demonstrate the importance of this channel income convergence continues in less regulated places while it has stopped in more regulated places

efficient liability rules for an economy with non identical individuals abstract this paper is about accident situations involving two risk neutral parties both parties engage in activities that are profitable but affect the magnitude of possible bilateral accidents we analyse how the activity choices can be decentralized by liability rules that assign the costs to the two parties to an accident we show that rules which share damages are superior to rules where one party bears the entire accident costs

litigation and settlement under two sided incomplete information this paper deals with a simple game of litigation and settlement with incomplete information parties are assumed to have the choice between settling their dispute out of court or resorting to costly litigation the set of sequential equilibria is characterized and conditions are given under which an efficient equilibrium does exist efficient equilibria however will be ruled out by various tests of refinement a comparative statics analysis is carried out with respect to the quality of private information which parties are assumed to receive before any moves have to be made

socio economic status and child health does public health insurance narrow the drawing on evidence from the u s this paper examines the effects of public health insurance on children recent expansions of american public health insurance programs to previously ineligible children have created a great deal of variation that can be used to identify their effects results indicate that providing public insurance to poor children narrows socio economic gaps in utilization and health among children however inefficiencies and inequities in the allocation of health care remain which suggests that universality and outreach programs are also important components of the public health systems common in europe

climate grapevine phenology wine production and prices pauillac 1800 2009 this paper analyzes 19th and 20th century data from a well known chateau in bordeaux the dataset includes information on weather conditions starting dates of three phenological stages of grapevine prices and yields we discuss how these variables have evolved over the last two centuries we also study to what extent the impact of climate on yields and prices has changed over time our regression analysis suggests that the effect of temperature on yields has become weaker since the 19th century the influence on prices has on the contrary become stronger

predicting the quality and prices of bordeaux wine bordeaux wines have been made in much the same way for centuries this article shows that the variability in the quality and prices of bordeaux vintages is predicted by the weather that created the grapes the price equation provides a measure of the real rate of return to holding wines about 2 3 per annum and implies far greater variability in the early or en primeur wine prices than is observed the analysis provides a useful basis for assessing market inefficiency the effect of climate change on the wine industry and the role of expert opinion in determining wine prices

forecasting bordeaux wine prices using state space methods generic bordeaux red wine basic claret can be regarded as being similar to an agricultural commodity production volumes are substantial they are traded at high frequency and the quality of the

wine market prices and investment under uncertainty an econometric model for bordeaux crus classes this paper describes an econometric assessment of wine market prices for 21 of the crus classes ch teaux in the bordeaux region of france the model developed in the analysis attempt to define the relationship between factors that influence wine quality and those that influence wine prices characteristics of the models are 1 climate influences on grape composition acid and sugar levels 2 grape composition influences on market prices 3 subjective quality evaluations parker points on market prices and 4 the effects of age of the wine on market prices the results indicate that composition levels of merlot dominated wines are more climate sensitive than those from cabernet sauvignon dominated wines overall warm dry summers result in high sugar and low acid levels at harvest which in turn lead to higher quality wines wine market price sensitivity to parker point ratings indicates that properties with high cabernet sauvignon dominated wines are highly dependent on the external ratings while merlot dominated wines have a decreased rating sensitivity smaller properties tend to gain over proportionally from high ratings indicating great jumps in price from year to year additionally ch teaux that have experienced high ratings for past vintages exhibit great sensitivity to point steps in ratings for current vintages aging has a positive effect on bordeaux wine pricing this is due to the increasing maturity as well as the increasing absolute scarcity absolute scarcity of product is expressed by the size of the property with small properties producing less per vintage and therefore having less in the market additionally merlot dominated wines exhibit more maturing potential and profit more from aging than cabernet sauvignon dominated wines average per ch teau real annual profit ranges from 1 to 10 high levels of grape ripeness absolute scarcity and smaller properties that are dominated by merlot in their blend lead to the highest profits forecasts for a vintage not yet on the market indicates that 1995 is better than 1994 for both cabernet sauvignon and merlot dominated wines but that 1996 and 1997 are not as good as 1995 especially for merlot dominated wines 2001 elsevier science b v all rights reserved

health and financial strain evidence from the survey of consumer finances using data from the survey of consumer finances this study examines the relationship between health status and financial strain controlling for the dual endogeneity between the two factors simultaneous two stage probit models are estimated for self reported health status and three measures of financial strain the results from all three models indicate that poor health significantly increases the probability of financial strain there is little evidence that financial strain contributes to poor health the findings suggest that severe health conditions may result in larger financial burdens while large financial burdens are unlikely to accelerate a decline in health status in the end health may be contributing to widening financial disparities especially among the poor who are in poor health

the price of wine abstract using historical price records for bordeaux premiers crus we examine the impact of aging on wine prices and the long term investment performance of fine wine in line with the predictions of an illustrative model young maturing wines from high quality vintages provide the highest financial returns past maturity famous ch teaus deliver growing non pecuniary benefits to their owners using an arithmetic repeat sales regression over 1900 2012 we estimate a real financial return to wine investment net of storage costs of 4 1 which exceeds bonds art and stamps returns to wine and equities are positively correlated finally we find evidence of in sample return predictability

natural resource abundance and healthcare efficiency in appalachia a robust conditional approach abstract this study investigates the role of natural resource abundance on healthcare efficiency in appalachia unconditional efficiency measures are calculated from a production process where health inputs are turned into health outcomes we utilize a non parametric robust order m estimator where we condition our efficiency measures on secondary environmental variables that do not directly impact health in a production process unlike the unconditional estimation procedure which impacts the shape of the production frontier as well as the distance to the frontier the secondary environmental variables alter the location of the production frontier with corresponding effects on efficiency we find that taking into account the relatively worse socioeconomic and healthcare conditions in appalachia improves healthcare efficiency by 1 6 and 1 9 percentage points respectively the presence of natural resource extraction measured by oil natural gas or coal production worsens healthcare efficiency by 0 14 percentage points another vehicle of the resource curse regressing the conditional efficiency estimates on secondary environmental variables shows that counties with natural resource production are further from the production frontier and therefore more inefficient findings suggest that policymakers can improve health efficiency by incentivizing positive health behaviors such as reduced obesity and smoking rates which would mimic health improving inputs in a production process

persistence in health limitations a european comparative analysis this paper investigates the persistence in health limitations for individuals within the member states of the european union we use the full eight waves of data available in the european community household panel echp to explore the relative contributions of state dependence unobserved heterogeneity and socioeconomic characteristics in particular income education and activity status and how these vary across countries we focus on binary measures of health limitations constructed from the answers to the question are you hampered in your daily activities by any physical or mental health problem illness or disability dynamic non linear panel data models are specified and estimated using both pooled and random effects probit and logit models together with complementary log log models the random effects probit specifications are preferred results reveal high state dependence of health limitations which remains after controlling for measures of socioeconomic status there is heterogeneity in the socioeconomic gradient across countries

using the law to change the custom the custom often acts as a powerful hindrance to equity increasing changes in this paper we present a simple model of legal dualism in which a progressive legal reform can under certain conditions shift the conflicting custom in the direction intended by the legislator formal law then acts as an outside anchor that exerts a magnet effect on the custom we also characterize the conditions under which a moderate reform performs better than a radical one in improving the welfare of the disadvantaged sections of the population we illustrate our insights using examples on inheritance marriage and divorce in sub saharan africa and india

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

no win no fee some economics of contingent legal fees mark up in different types of case is to be issued after consultation with professional bodies american style share contracts whereby the lawyer is paid a proportion of the award if the case is won and nothing if it is lost will continue to be unenforceable at law and prohibited by the professional bodies the introduction of contingency fees in england and wales has been discussed in a number of official and semi official reports without any consensus emerging 3 we use a formal model of the litigation process to analyse the implications of contingent fees under both english and united states cost shifting rules in the model potential defendants can take care to avoid accidents which impose losses on potential plaintiffs if an accident occurs the defendant is sued by the plaintiff and makes a settlement offer if the plaintiff rejects the offer the case proceeds to trial plaintiffs who win at trial are awarded damages and under english rules costs against the defendant lawyer client contracts can be evaluated by the extent to which they a compensate plaintiffs after an accident by making it easy to sue and obtain redress b induce settlements rather than costly trials and c provide

a test of racial bias in capital sentencing this paper proposes a test of racial bias in capital sentencing based upon patterns of judicial errors in lower courts we model the behavior of the trial court as minimizing a weighted sum of the probability of sentencing an innocent and that of letting a guilty defendant free we de ne racial bias as a situation where the relative weight on the two types of errors is a function of defendant and or victim race the key prediction of the model is that if the court is unbiased ex post the error rate should be independent of the combination of defendant and victim race we test this prediction using an original dataset that contains the the race of the defendant and of the victim s for all capital appeals that became nal between 1973 and 1995 we nd robust evidence of bias against minority defendants who killed white victims in direct appeal and habeas corpus the probability of error in these cases is 3 and 9 percentage points higher respectively than for minority defendants who killed minority victims

self assessed health reference levels and mortality the paper studies the relationship between self assessed health and subsequent mortality in the german socio economic panel specifically i examine whether socio economic characteristics of respondents have an effect on mortality conditional on self assessed health such conditional effects are shown to exist for various covariates including age income and wealth these findings question the comparability of self assessed health across different socio economic groups

income productivity in china on the role of health this study provides empirical evidence regarding the income productivity of health human capital in china we appeal to concepts from human capital theory to support a basic model that treats health as a form of human capital in the income production process our model examines the economic return at the household level from the health of its individual members we estimate this with a longitudinal sample drawn from the china health and nutrition survey chns allowing us to exploit within variation in health and income to address possible unobservables biasing estimates of the impact of health on income in the simple cross sectional setting household income is strongly influenced by the health of its members particularly in rural areas these findings could have important implications for health and economic policy making aimed at reducing the long standing urban rural economic gap and more comprehensively insuring the rural population against health and economic risk

endogenous cases and the evolution of the common law i develop a dynamic model of judge made law in which the ideal legal rule is unknown but can be learned in contrast to existing articles the flow of cases heard by the court is affected by the court s prior decisions the model highlights the significance of this feedback in explaining when and why the court will write broader or narrower opinions and the long run properties of common law in equilibrium the law settles endogenously because the incentives to make legally controversial choices disappear as the law evolves settled law exhibits residual uncertainty and ambiguity and potentially implements inefficient outcomes

voluntary product safety certification this paper describes the incentives for firms to seek voluntary product safety certifications we consider a firm that makes the decision of whether or not to seek certification prior to selling the product we show that even when the firm and the consumers have the same beliefs about the product s safety there are incentives for the firm to seek safety certification the main analysis investigates the role of consumer moral hazard and shows that it can lead to greater incentives for voluntary certification when inherent product safety and effort are substitutes but smaller incentives when they are complements the analysis of consumer moral hazard provides a nuanced perspective on the so called risk compensation or the peltzman effect phenomenon which postulates higher levels of accidents for safer products in our paper products that are successfully certified can end up with a higher incidence of accidents we also uncover an interesting nonmonotonic relationship between effectiveness of consumer

family income and child outcomes in canada a positive relationship between income and child outcomes has been observed in data from numerous countries a key question concerns the extent to which this association represents a causal relationship as opposed to unobserved heterogeneity we use data from the national longitudinal survey of children and youth to implement a series of empirical strategies for estimating the existence and size of the effect of income on three measures of cognition our results indicate that the effect of income on these outcomes may well be positive but that it is likely to be smaller than conventional estimates jel classification i10 revenu des familles et comportement des enfants au canada il existe une relation positive entre le revenu des familles et les comportements des enfants dans les releves statistiques de nombreux pays une question centrale demeure jusqu a quel point est ce que cette correlation represente une relation causale par opposition a du bruit les auteurs utilisent l enquete longitudinale nationale sur les enfants et les jeunes elnej pour mettre en place une serie de strategies empiriques pour calibrer l existence et la taille de l effet de revenu sur trois mesures de cognition les resultats montrent que l effet de revenu sur ces comportements peut fort bien etre positif mais qu il est vraisemblablement plus faible que ce que suggerent les evaluations conventionnelles

fair retirement under risky lifetime a premature death unexpectedly brings a life and a career to their end leading to substantial welfare losses we study the retirement decision in an economy with risky lifetime and compare the laissez faire with egalitarian social optima we consider two social objectives 1 the maximin on expected lifetime welfare allowing for a compensation for unequal life expectancies and 2 the maximin on realized lifetime welfare allowing for a compensation for unequal lifetimes the latter optimum involves in general decreasing lifetime consumption profiles as well as raising the retirement age this result is robust to the introduction of unequal life expectancies and unequal productivities

legal efficiency and consistency abstract we analyze the efficiency and consistency of court decisions under common and civil law as a leading example we study the enforcement of property rights judges are of two types some are conservative and follow the precedent or the statute while others maximize social welfare when courts intervene ex post after the relevant economic choices have been made welfare maximizing courts face a commitment problem such an ex post bias has implications on the relative consistency and efficiency of each legal system surprisingly we find that court decisions are more consistent under common law than under civil law the welfare comparison between the two systems is instead ambiguous however in changing economic environments common law is more likely to dominate civil law because of its greater adaptability

estimation of a hedonic price equation for bordeaux wine does quality matter in this paper the hedonic price technique is applied to bordeaux wine in the hedonic price function we include not only the objective characteristics appearing on the label of the bottle but also the sensory characteristics of the wine our data come from an experimental study in which juries have evaluated and graded a sample of bordeaux wines the estimation of the hedonic price equation shows that the market price is essentially determined by the objective characteristics the estimation of a jury grade equation shows that quality unlike the market price is essentially determined by the sensory characteristics

money transfer and birth weight evidence from the alaska permanent fund dividend the positive relationship between income and health is well established however the direction of causality remains unclear do economic resources influence health or vice versa exploiting a new source of exogenous income variation this study examines the impact of the alaska permanent fund dividend apfd on newborns health outcomes the results show that income has a significantly positive but modest effect on birth weight we find that an additional 1 000 2 331 in 2011 dollars increases birth weight by 17 7 g and substantially decreases the likelihood of a low birth weight a decrease of around 14 of the sample mean furthermore the income effect is higher for less educated mothers based on a gestation weight profile in the sample increased gestation owing to the apfd could explain a maximum of 34 57 of the measured weight increase although we are unable to examine all the potential mechanisms jel i10 i18 i12

financially constrained lawyers an economic theory of legal disputes abstract financial constraints reduce the lawyer s ability to file lawsuits and bring cases to trial as a result access to justice for victims pretrial bargaining and potential injurers precaution might be affected we study civil litigation using a model that allows for asymmetric information financially constrained lawyers third party lawyer lending and a continuum of plaintiff s types we contribute to the economic analysis of law by generalizing seminal models of litigation bebchuk 1984 bebchuk 1988 katz 1990 offering the first formal definition of access to justice and presenting comprehensive social welfare analysis of relevant public policy we provide complete equilibrium characterization and identify necessary conditions for the existence of the mixed and pure strategy pbe access to justice is denied to some victims under the mixed strategy equilibrium we then study the social welfare effects of policies aimed at relaxing lawyers financial constraints and identify a necessary and sufficient condition for a welfare enhancing effect

intergenerational health mobility an empirical approach based on the echp despite the importance of the study of health mobility few attempts have been made to measure intergenerational mobility not only in the european union but also in other countries such as united states this article is focused on the study of intergenerational health mobility using data from the european community household panel echp in particular the relationships between self assessed health of parents and their sons are analysed the evidence obtained suggests that in spain sons reported health depends significantly on the self assessed health of their fathers

health insurance eligibility utilization of medical care and child health two economists applied data from the current population survey and the national health interview survey and state level data on child mortality to a simulation model of utilization of medical care that varies only with the states legislative environment to examine the utilization of medical care and health effects of medicaid eligibility on low income children the models took into consideration the recent expansions of medicaid to low income children 38 of those ineligible for medicaid in 1984 who became eligible due to changes during 1984 1992 were uninsured between 1984 and 1992 expansions of the medicaid program increased the proportion of children eligible for medicaid almost two fold 16 1 vs 31 2 yet coverage rates were always lower than eligibility rates 13 2 vs 16 1 in 1984 and 20 3 vs 31 2 in 1992 and the increase in coverage rates was only about 50 of the increase in eligibility rates during 1984 1992 the probability that a child was eligible for medicaid increased the probability of health insurance coverage by 29 77 when the model considered bias in variables e g a recession in a state the take up rate was only 22 73 nevertheless medicaid markedly increased use of medical care for example eligibility for medicaid increased the likelihood of making a visit to a physicians office in the last two weeks by about 50 it also increased the probability of a child visiting the hospital suggesting inefficiency in the way that providers deliver care to medicaid enrollees medicaid eligibility had a significant effect on reducing child mortality the 15 1 percentage point increase in eligibility during 1984 1992 reduced child mortality by 4 5 when the researchers examined parent assessed subjective health measures medicaid eligibility had no effect on child health medicaid eligibility reduced race and education based disparities in the number of visits and racial differences in mortality yet it may actually intensify current disparities in health care delivery site
