a soft pillow for hard times economic insecurity food intake and body weight in russia this study investigates causal effects of economic insecurity on subjective anxiety food intake and weight outcomes a review of psychological and nutrition studies highlights the complexity of processes at work on each stage of this causal chain econometric analyses trace the effects along the hypothesized pathway using detailed household panel data from the russia longitudinal monitoring survey from 1994 to 2005 economic insecurity measures serve as key explanatory variables in regressions and are instrumented by exogenous regional indicators results support a causal chain from economic insecurity to weight outcomes for some population subgroups in contrast to the leading hypothesis that economic insecurity increases body weight i find strong evidence of a decreasing effect among women results suggest further that consumption of foods rich in sugar responds strongly to higher levels of economic insecurity heterogeneous impacts of economic insecurity on body weight call for individual level interventions rather than large scale action

physical appearance and wages do blondes have more fun abstract this study contributes to the economics literature that links physical characteristics to labour market outcomes by investigating the influence of hair colour on women s own wages and also their spouse s wages using u s panel data we find that blonde women receive large wage premiums

the economic value of teeth abstract this paper examines the effect of oral health on labor market outcomes by exploiting variation in fluoridated water exposure during childhood the politics surrounding the adoption of water fluoridation by local governments suggests exposure to fluoride is exogenous to other factors affecting earnings exposure to fluoridated water increases women s earnings by approximately 4 percent but has no detectable effect for men furthermore the effect is largely concentrated amongst women from families of low socioeconomic status we find little evidence to support occupational sorting statistical discrimination and productivity as potential channels with some evidence supporting consumer and possibly employer discrimination

wealth accumulation over the life cycle and precautionary savings this article constructs and simulates a life cycle model of wealth accumulation and estimates the parameters of the utility function the rate of time preference and the coefficient of risk aversion by matching the simulated median wealth profiles with those observed in the panel study of income dynamics and in the survey of consumer finances the estimates imply a low degree of patience and a high degree of risk aversion the results are used to study the importance of precautionary savings in explaining wealth accumulation they imply that wealth accumulation is driven mostly by precautionary motives at the beginning of the life cycle whereas savings for retirement purposes become significant only closer to retirement

the impact of body weight on occupational mobility and career development this paper examines the relationship between individuals weight and their employment decisions over the life cycle i estimate a dynamic stochastic model of individuals annual joint decisions of occupation hours worked and schooling the model allows body weight to affect non monetary costs switching costs and distribution of wages for each occupation and also allows individuals employment decisions to affect body weight i use conditional density estimation to formulate the distributions of wages and body weight evolution i find that heavier individuals face higher switching costs when transitioning into white collar occupations earn lower returns to experience in white collar occupations and earn lower wages in socially intensive jobs simulating the model with estimated parameters decreased occupational mobility accounts for 10 percent of the obesity wage gap while contemporaneous wage penalties for body weight are small the cost over the life cycle is substantial an exogenous increase in initial body mass by 20 percent leads to a 10 percent decrease in wages over the life course

supply side and demand side cost sharing in deregulated social health insurance which is more effective abstract microeconomic theory predicts that if patients are fully insured and providers are paid fee for service utilization of medical services exceeds the efficient level moral hazard effect in switzerland both demand side and supply side cost sharing have been introduced to mitigate this problem analyzing a panel dataset of about 160 000 adults we find both types of cost sharing to be effective in curtailing the use of medical services however when moral hazard mitigation is traded off against risk selection the minimum deductible supply side cost sharing option ranks first followed by the medium deductible demand side alternative making the supply side option somewhat more effective

beauty and the labor market the authors examine the impact of looks on earnings using interviewers ratings of respondents physical appearance plain people earn less than average looking people who earn less than the good looking the plainness penalty is 5 to 10 percent slightly larger than the beauty premium effects for men are at least as great as for women unattractive women have lower labor force participation rates and marry men with less human capital better looking people sort into occupations where beauty may be more productive but the impact of individuals looks is mostly independent of occupation suggesting the existence of pure employer discrimination copyright 1994 by american economic association

does public insurance crowd out private insurance the cost of expanding public sector health programs depends critically on the extent to which public eligibility will cover just the uninsured or will crowd out existing private insurance coverage we estimate the extent of crowd out arising from the expansions of medicaid to pregnant women and children over the 1987 1992 period we estimate that approximately 50 percent of the increase in medicaid coverage was associated with a reduction in private insurance coverage this occurred largely because employees took up employer based insurance less frequently there is also some evidence that employers contributed less for insurance and that workers dropped coverage of dependents

on the distribution and dynamics of health care costs using data from the health and retirement survey and the assets and health dynamics of the oldest old survey we estimate the stochastic process that determines both the distribution and dynamics of health care costs we find that the data generating process for log health costs is well represented as the sum of a white noise process and a highly persistent ar 1 process we also find that the innovations to this process can be modelled with a normal distribution that has been adjusted to capture the risk of catastrophic health care costs simulating this model we find that in any given year 0 1 of households receive a health cost shock with a present value of at least 125 000 copyright 2004 john wiley sons ltd

bayesian analysis of the two part model with endogeneity application to health care expenditure this paper studies the effect of managed care on medical expenditure using a model in which the insurance status is assumed to be endogenous insurance plan choice is modeled through the multinomial probit model the medical expenditure variable the outcome of interest has a significant proportion of zeros that are handled using the two part model extended to handle endogenous insurance the estimation approach is bayesian based on the gibbs sampler the model is applied to a sample of 20 460 individuals obtained from the medical expenditure panel survey the results provide substantial evidence of selectivity copyright 2006 john wiley sons ltd

the impact of obesity on wages abstract previous studies of the relationship between body weight and wages have found mixed results this paper uses a larger data set and several regres sion strategies in an attempt to generate more consistent estimates of the effect of weight on wages differences across gender race and ethnicity are explored this paperjnds that weight lowers wages for white females ols esti mates indicate that a difference in weight of two standard deviations roughly 65 pounds is associated with a difference in wages of 9 percent in absolute value this is equivalent to the wage effect of roughly one and a half years of education or three years of work experience negative cor relations between weight and wages observed for other gender ethnic groups appear to be due to unobserved heterogeneity i introduction several previous studies have found among females a negative cor relation between body weight and wages there exist three broad categories of ex planations for this finding the first explanation is that obesity lowers wages for example by lowering productivity or because of workplace discrimination the sec ond is that low wages cause obesity this would be true if poorer people consume

private insurance selection and health care use observed differences in medical utilization between the privately insured and uninsured reflect the combined effects of self selection and insurance incentives moral hazard this article provides a bayesian framework for decomposing the disparity into incentive and selection components the effect of self selection in private insurance on the number of doctor visits is estimated using a multiyear sample of the u s adult non medicare population obtained from the medical expenditure panel survey we use a flexible econometric framework based on the roy model and develop a markov chain monte carlo algorithm we estimate the distribution of treatment effects and find strong evidence indicating selection which accounts on average for 50 or more of the observed disparity in doctor visits

making retirement income last a lifetime to enable investors to spend down the assets in their defined contribution accounts more easily the authors propose a decumulation benchmark comprising a laddered portfolio of tips for the first 20 years consuming 88 percent of available capital and a deferred life annuity purchased with the remaining 12 percent this portfolio can be used directly by the investor akin to indexing or as a benchmark for evaluating the performance of a more aggressive strategy

the labour market impact of body weight in china a semiparametric analysis while a positive wage effect of body mass index bmi is widely observed in low income developing countries a negative wage effect of bmi is often observed in high income developed countries to fill the gap between these previous findings we investigate the relationship between body weight and wages in transition economies we focus on china whose rapid economic growth of the 1990s was followed by a rapid increase in overweight and obesity while still experiencing significant food insecurity and underweight we first use several parametric regression strategies to obtain a consistent estimate of the wage effects of weight second we adopt a semiparametric partially linear model that allows for endogeneity of weight parametric regressions provide mixed results and the sign and magnitude of their estimates are sensitive to the choice of samples and regression strategies semiparametric estimates provide evidence of a wage penalty for very heavy and thin persons among both men and women the wage pena

what are the consequences of consequentiality abstract we investigate the extent to which dichotomous choice referenda responses are shaped by whether the individual believes the survey itself will ultimately impact policy using survey data from the iowa lakes project we test this supposition specifically we employ a bayesian treatment effect model in which the degree of perceived consequentiality measured as an ordinal response is permitted to have a structural impact on willingness to pay wtp for a hypothetical environmental improvement we test whether the estimated wtp distributions are the same for each value of the ordinal response in our survey data a subsample of individuals were randomly assigned supporting information suggesting that their responses to the questionnaires were important and will have an impact on policy decisions in conjunction with a bayesian posterior simulator we use this source of exogenous variation to identify the structural impacts of consequentiality perceptions on willingness to pay while controlling for the potential of confounding on unobservables we find evidence consistent with a knife edge result namely that the willingness to pay distributions are equal among those believing the survey to be at least minimally consequential and different for those believing that the survey is irrelevant for policy purposes

uncertain medical expenses and precautionary saving near the end of the life cycle this paper introduces a dynamic structural model of household consumption decisions in which elderly families consider the effects of uncertain future medical expenses when deciding current levels of consumption the model with uncertain medical expenses implies a potentially important role for precautionary saving incentives to explain slow rates of dissaving among elderly americans during retirement rather than just simulating the stochastic dynamic model preference parameters are estimated using panel data on health wealth and expenditures for retired families the health uncertainty model predicts consumption levels closer to observed expenditures than a life cycle model with uncertain longevity however elderly families typically dissave their financial assets more slowly than even the baseline health uncertainty model predicts is optimal

who pays for obesity adult obesity is a growing problem from 1962 to 2006 obesity prevalence nearly tripled to 35 1 percent of adults the rising prevalence of obesity is not limited to a particular socioeconomic group and is not unique to the united states should this widespread obesity epidemic be a cause for alarm from a personal health perspective the answer is an emphatic yes but when it comes to justifications of public policy for reducing obesity the analysis becomes more complex a common starting point is the assertion that those who are obese impose higher health costs on the rest of the population a statement which is then taken to justify public policy interventions but the question of who pays for obesity is an empirical one and it involves analysis of how obese people fare in labor markets and health insurance markets we will argue that the existing literature on these topics suggests that obese people on average do bear the costs and benefits of their eating and exercise habits we begin by estimating the lifetime costs of obesity we then discuss the extent to which private health insurance pools together obese and thin whether health insurance causes obesity and whether being fat might actually cause positive externalities for those who are not obese if public policy to reduce obesity is not justified on the grounds of external costs imposed on others then the remaining potential justification would need to be on the basis of helping people to address problems of ignorance or self control that lead to obesity in the conclusion we offer a few thoughts about some complexities of such a justification

gluttony and sloth calories labour market activity and the rise of obesity the rise in obesity has largely been attributed to an increase in calorie consumption we show that official government household survey data indicate that levels of calorie consumption have declined in england between 1980 and 2013 while there has been an increase in calories from food eaten out at restaurants fast food soft drinks and confectionery overall there has been a decrease in total calories purchased households have shifted towards more expensive calories both by substituting away from home production towards market production and substituting towards higher quality foods we show that the decline in calories can be partially but not entirely rationalized with weight gain by a decline in the strenuousness of work and daily life jel d12 i12 i18

treatment effect heterogeneity in theory and practice instrumental variables iv methods identify internally valid causal effects for individuals whose treatment status is manipulable by the instrument at hand inference for other populations requires homogeneity assumptions this paper outlines a theoretical framework that nests causal homogeneity assumptions these ideas are illustrated using sibling sex composition to estimate the effect of childbearing on economic and marital outcomes the application is motivated by american welfare reform the empirical results generally support the notion of reduced labour supply and increased poverty as a consequence of childbearing but evidence on the impact of childbearing on marital stability and welfare use is more tenuous

much ado about two reconsidering retransformation and the two part model in health econometrics in health economics applications involving outcomes y and covariates x it is often the case that the central inferential problems of interest involve e y x and its associated partial effects or elasticities many such outcomes have two fundamental statistical properties y 0 and the outcome y 0 is observed with sufficient frequency that the zeros cannot be ignored econometrically this paper 1 describes circumstances where the standard two part model with homoskedastic retransformation will fail to provide consistent inferences about important policy parameters and 2 demonstrates some alternative approaches that are likely to prove helpful in applications

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

international dimensions of obesity and overweight related problems an economics perspective obesity is a growing concern new world health organization who figures indicate that obesity is spreading around the world as a global epidemic according to the who there are more people suffering from overweight related problems than malnutrition globally there are more than 1 billion adults who are overweight and at least 300 million of them are clinically obese while 800 million suffer from malnutrition who 2004 the economic costs due to obesity can be burdensome currently in the united states medical costs associated with obesity and smoking account for about 9 each of all health expenditures finkelstein fiebelkorn and wang u s obesity attributable medical expenditures reached 75 billion in 2003 obesity however is important not only from an economic perspective but also from a social perspective the social consequences of obesity are serious and multiple studies have shown that obesity affects in a negative and statistically significant way personal and working relations earnings and wages particularly for females cawley overall obesity is a complex phenomenon several recent economic studies have explored the role of different cultural and sociodemographic factors on obesity rates leaving genetics aside obesity is caused by the consumption of too many calories and or low expenditures of calories i e low physical activity consequently most published economic research provided a justification for the increased growth of obesity rates by analyzing several factors that may contribute to this imbalance of caloric consumption and usage see chou grossman and saffer cutler glaeser and shapiro lakdawalla and philipson philipson and posner there are mainly two arguments that could justify the growth of overweight problems around the world some researchers argue that obesity growth is mainly due to a higher intake of calories while others state that obesity is mainly caused by a lower expenditure of caloies in daily activities in line with the calorie consumption argument cutler glaeser and shapiro stated that americans have become more obese over the past twenty five years primarily due to the consumption of more calories analyzing changes in food consumption between the mid 1970s and the mid 1990s for

reducing sequence risk using trend following and the cape ratio the risk of experiencing bad investment outcomes at the wrong time or sequence risk is a poorly understood but crucial aspect of the risk investors face particularly those in the decumulation phase of their savings journey typically over the period of retirement financed by a defined contribution pension scheme using us equity return data for 1872 2014 we show how this risk can be significantly reduced by applying trend following investment strategies we also show that knowing a valuation ratio such as the cyclically adjusted price to earnings cape ratio at the beginning of a decumulation period is useful for enhancing sustainable investment income

public insurance and private savings who is affected and by how much this paper employs a recently developed instrumental quantile regression method to investigate the effect of medicaid on household savings across different wealth groups it finds that the disincentive effect of medicaid on household savings is heavily concentrated in the middle net worth households in contrast the effects on the bottom and top net worth households are quite small and insignificant these heterogeneous incentive effects are partly explained by medicaid asset tests our findings hold regardless of whether affluence is measured in terms of wealth or income they suggest that despite generating substantial crowd out for the mean household medicaid expansions are unlikely to discourage the savings of the poorest households copyright 2008 john wiley sons ltd

the wages of bmi bayesian analysis of a skewed treatment response model with nonparametric endogeneity we generalize the specifications used in previous studies of the effect of body mass index bmi on earnings by allowing the potentially endogenous bmi variable to enter the log wage equation nonparametrically we introduce a bayesian posterior simulator for fitting our model that permits a nonparametric treatment of the endogenous bmi variable flexibly accommodates skew in the bmi distribution and whose implementation requires only gibbs steps using data from the 1970 british cohort study our results indicate the presence of nonlinearities in the relationships between bmi and log wages that differ across men and women and also suggest the importance of unobserved confounding for our sample of males copyright 2008 john wiley sons ltd

a sustainable spending rate without simulation financial commentators have called for more research on sustainable spending rates for individuals and endowments holding diversified portfolios we present a forward looking framework for analyzing spending rates and introduce a simple measure stochastic present value that parsimoniously meshes investment risk and return mortality estimates and spending rates without resorting to opaque monte carlo simulations applying it with reasonable estimates of future returns we find payout ratios should be lower than those many advisors recommend the proposed method helps analysts advise their clients how much they can consume from their savings whether they can retire early and how to allocate their assets

what lies behind socio economic inequalities in obesity in spain a decomposition approach the expansion of obesity stands as a major food related health concern arguably driven by a socio economic vector however alongside its prevalence still scant evidence has examined on the underlying factors that explain the emergence socio economic inequalities in obesity this paper makes use of evidence form spain to empirically address the hypothesis of the existence of income related inequalities in the probability of suffering obesity in spain using data from 2003 besides quantifying inequalities we take advantage of a concentration index methodology that allows a decomposition of the cross section explanatory factors our findings provide suggestive evidence of significant socio economic inequalities in the probability of being obese in spain however in decomposing such inequalities we find that education attainment and other demographic covariates appear to have a prominent influence hence rather than the so called pure income effect we conclude that socio economic inequalities in obesity result from the additional influence of other confounding observed and unobserved effects

do welfare asset limits affect household saving evidence from welfare reform we use data from the panel study of income dynamics to estimate the effect of new saving incentives implemented as part of the 1996 welfare reform on household saving economic theory predicts that loosening asset limits will increase total savings for households with a large ex ante probability of welfare receipt such as female headed households with children we follow a sample of female heads with children and find that in both absolute terms and relative to comparison groups of male heads and female heads without children there has been no effect of welfare policy changes on the saving of at risk households

does weight status affect academic performance evidence from australian children abstractthis article investigates the impact of children s weight status on their academic performance using the longitudinal survey of australian children considering the endogeneity of the weight status variable obesity or overweight to obtain consistent estimates of its impact we use the body mass index of biological parents as instrumental variables the two stage least square estimation shows that obesity or overweight has a significant negative impact on academic performance furthermore the effect of child weight status is different across grade levels overweight has a larger negative impact on academic performance for senior year students especially on numeracy

gender differences physical activity and body weight we investigate the effect of physical activity on bodyweight and the gender differences in such effects following the copula approach to endogenous switching regression using data from the 2006 behavioral risk factor surveillance system brfss we find differentiated effects of socio demographic variables on exercise and on body mass indexes bmis and differentiated effects of exercise on bmi between genders regular exercise on average decreases bmi by 1 78 for women and 1 01 for men food price away from home has negative effects on bmi of both men and women

national health insurance and precautionary saving evidence from taiwan abstract by reducing uncertainty about future medical expenses comprehensive health insurance can reduce households precautionary saving we examine this effect using taiwan micro data spanning the 1995 introduction of national health insurance the effects of national health insurance are identified using employment based variation in prior insurance coverage replacement of the households prior insurance coverage with national health insurance is exogenous to the household so our estimates are not subject to selection bias compared with the preceding government insurance programs national health insurance reduced saving by an average of 8 6 13 7 with the largest effects for households with the smallest saving

should social security benefits be means tested social security retirement benefits distort the saving decisions of workers who are rational enough to save for their future since the implicit rate of return in an unfunded social security program is less than the marginal product of capital the resulting decline in saving causes a welfare loss the present paper examines the conditions under which the welfare loss could be reduced by replacing the current universal social security program with a means tested program that pays benefits only to those individuals with little or no other retirement income or assets every society must solve the problem of supporting those individuals who become too old to work but have not made adequate provision for their own old age by saving when they were young at the present time the major industrial countries of the world have responded to this problem by creating social security programs that tax the working population and use the proceeds to provide a universal benefit to all retirees regardless of their financial condition this universal provision of social security benefits distorts the saving decisions of those workers who are rational enough to plan for the future since the implicit rate of return that taxpayers get on their this research is part of the nber study of the government budget and the private economy a more complete version of this paper with some numerical calculations is available as nber working paper no 1775 feldstein 1985b i am grateful to gilbert metcalf for assistance with the calculations presented in this paper and for helpful discussions for a discussion of the effect of promised retirement benefits on the savings of employees see feldstein 1974 1982 barro 1974 1978 has discussed an interesting

heterogeneous impact of the seguro popular program on the utilization of obstetrical services in mexico 2001 2006 a multinomial probit model with a discrete endogenous variable objective we evaluated the impact of seguro popular sp a program introduced in 2001 in mexico primarily to finance health care for the poor we focused on the effect of household enrollment in sp on pregnant women s access to obstetrical services an important outcome measure of both maternal and infant health

can social programs break the vicious cycle between poverty and obesity evidence from urban mexico abstract this article analyzes how social interventions offer a solution to counteract the spread of overweight among the poor focusing on the mexican conditional cash transfers program we assess the average effect of a long run enrollment on adult body mass index and waist to height ratio an original triple difference approach which distinguishes over time participants from nonparticipants and stayers from leavers is implemented we find that the expansion of this program to urban areas has a protective effect on adult bodyweight for staying participants but not an absolute effect moreover the global impact of the program to reduce obesity is halved due to a low rate of participation in mexican cities furthermore we find health risky externalities related to the cash component of the program indeed the amount of cash payments is positively correlated with abdominal fat concentration especially among enrolled women and for short run enrollments to sum up our results bring new insights to the complementary role of both program components cash and conditionalities

weight discrimination in the german labour market abstractwe explore the effects of higher body mass index bmi or obesity on different labour market outcomes we extend the present literature by investigating the effect of obesity on i promotion likelihood and ii unemployment duration in addition to the effect on iii wages and iv probability of being employed we find an obesity penalty on wages employment likelihood promotion likelihood and unemployment duration among females in germany taking into account of endogeneity of bmi and sample selection we are also able to identify an unexplained effect of obesity on wages employment and promotion likelihood for females using decomposition techniques that can be attributed to weight discrimination

paying for health insurance the trade off between competition and adverse selection we use data on health plan choices by employees of harvard university to compare the benefits of insurance competition with the costs of adverse selection moving to a voucher type system induced significant adverse selection with a welfare loss of 2 to 4 percent of baseline spending but increased competition reduced harvard s premiums by 5 to 8 percent the premium reductions came from insurer profits so while harvard was better off the net effect for society was only the adverse selection loss adverse selection can be minimized by adjusting voucher amounts for individual risk we discuss how such a system would work governments are increasingly turning to market forces as a way to limit the cost of social insurance traditionally social insurance programs were operated as nonmarket goods governments mandated participation in a central program collected revenues to finance the program and ran the insurance system there was no role for competition among suppliers in providing the basic benefit as the costs of social insurance have increased however the centralized model of social insurance is coming under increasing strain in the united states for example recent proposals have called for replacing the medicare program with a health care voucher for the elderly aaron and reischauer 1995 cutler 1996 the voucher would guarantee people a basic insurance plan but the plans would be privately run competition among plans would generate plan premiums and enrollments similarly longstanding proposals for social security reform have called for replacing the current system with a system of individual accounts where people would make saving investment and annuitization decisions on their own advisory council on social security 1996 feldstein 1996 the trend is not just domestic in the united kingdom the national health service has moved to encourage more competition in recent years with the establishment of hospital trusts that bid for patients and partially fixed payments to physicians

an economy of scales a selective review of obesity s economic causes consequences and solutions this paper reviews the economic research on obesity covering topics such as the measurement of and trends in obesity the economic causes of obesity e g the monetary price and time cost of food food assistance programs income education macroeconomic conditions and peer effects and the economic consequences of obesity e g lower wages a lower probability of employment and higher medical care costs it also examines the extent to which obesity imposes negative externalities and economic interventions that could potentially internalize such externalities such as food taxes subsidies for school based physical activity programs and financial rewards for weight loss it discusses other economic rationales for government intervention with respect to obesity such as imperfect information time inconsistent preferences and irrational behavior it concludes by proposing a research agenda for the field overall the evidence suggests that there is no single dominant economic cause of obesity a wide variety of factors may contribute a modest amount to the risk there is consistent evidence regarding the economic consequences of obesity which are lower wages and higher medical care costs that impose negative externalities through health insurance studies of economic approaches to preventing obesity such as menu labeling taxes on energy dense foods and financial rewards for weight loss find only modest effects on weight and thus a range of policies may be necessary to have a substantial effect on the prevalence of obesity

does means testing welfare discourage saving evidence from a change in afdc policy in the united states abstract this paper provides empirical evidence on the impact of a welfare program s asset test on the saving behavior of its target population the approach exploits a policy experiment the essential federalization of the afdc program s asset testing policy in 1981 data on female headed households from the national longitudinal survey young women are used to test the hypothesis that likely afdc users adjusted their asset stocks in response to this change the findings indicate additional saving between 1978 and 1983 of about 25 cents for each additional 1 increase in the limit in most states

parametric and semi parametric modelling of vacation expenditures we analyse several limited dependent variable models explaining the budget share that dutch families spend on vacations to take account of the substantial number of zero shares two types of models are used the first is the single equation censored regression model we estimate and test several parametric and semi parametric extensions of the tobit model second we consider two equation models in which the participation decision and the decision on the amount to spend are treated separately the first decision is modelled as a binary choice model the second as a conditional regression we estimate and test parametric and semi parametric specifications

a pension promise to oneself saving for retirement is not hopeless well run db pension plans provided retirement income for generations when plans failed it is because they broke the rules the same applies to individuals by understanding a set of rules on how much to save and how to invest and then sticking to those rules that is by making a pension promise to oneself retirement income goals can be met fulfilling this promise requires more saving than most people are accustomed to

heterogeneity of the effects of health insurance on household savings evidence from rural china summary we estimate the impact of the new cooperative medical scheme ncms on household savings by income quartiles in rural china we control for endogenous ncms participation with an instrumental variable strategy using the china health and nutrition survey we find that ncms has a negative impact on middle income savings but does not affect the poorest participants ncms also decreases richest participants savings when they do not benefit from other health programs thus the implementation of a health care scheme appears to be an appropriate tool to lower savings and boost consumption and so sustain economic growth

the only spending rule article you will ever need after examining an array of approaches to determining a spending rule for retirees the authors propose the annually recalculated virtual annuity each year one should spend at most the amount that a freshly purchased annuity with a purchase price equal to the then current portfolio value and priced at current interest rates and number of years of required cash flows remaining would pay out in that year investors who behave in this way will experience consumption that fluctuates with asset values but they can never run out of money

a comparison of alternative models for the demand for medical care we have tested alternative models of the demand for medical care using experimental data the estimated response of demand to insurance plan is sensitive to the model used we therefore use a split sample analysis and find that a model that more closely approximates distributional assumptions and uses a nonparametric retransformation factor performs better in terms of mean squared forecast error simpler models are inferior either because they are not robust to outliers e g anova anocova or because they are inconsistent when strong distributional assumptions are violated e g a two parameter box cox transformation

the effects of 401 k participation on the wealth distribution an instrumental quantile regression analysis we use instrumental quantile regression approach to examine the effects of 401 k plans on wealth using data from the survey of income and program participation using 401 k eligibility as an inst

gender bias and credit access we extract an exogenous measure of gender bias from survey responses by descendants of u s immigrants on questions about the role of women in society we then use data on around 6 000 small business firms from 17 countries and find that in high gender bias countries female entrepreneurs are more likely to opt out of the loan application process and to resort to informal finance even though banks do not appear to actively discriminate against them these results are not driven by credit risk differences between female and male owned firms or by any idiosyncrasies in the set of countries in our sample

when does weight matter most past empirical work establishes a wage penalty from being overweight in this paper i exploit variation in an individual s weight over time to determine the age when weight has the largest impact on labor market outcomes for white men controlling for weight at younger ages does not eliminate the effect of older adult weight on wage being overweight as a young adult only adds an additional penalty to adult wages however for white women what they weigh in their early twenties solely determines the existence of an adult wage penalty the female early twenties weight penalty has a persistent effect on wages and differences in marital characteristics occupation status or education cannot explain it it also is not a proxy for intergenerational unobservables

effects of physical activity on earnings in the brazilian labor market abstract this article investigates the effects of physical activity on earnings in the brazilian labor market analyzing workers aged between 30 and 50 years to that end quantile regression was applied to analyze microdata from the 2008 national household sample survey pnad the results showed that workers who engage in regular physical exercise exhibit better social and economic conditions compared to sedentary individuals sedentary lifestyles are typically more common among female employees than their male counterparts and this is reflected in earnings in the labor market the impact of physical activity on wages varied from 15 0 to 31 0 and was greater among the highest quantiles the lowest salaries were recorded among non white sedentary women

marginal effects of a bivariate binary choice model this paper discusses the copula based approach of a bivariate binary choice model we derive the marginal effects of explanatory variables on an outcome of interest both direct and indirect in the model we also show that the signs of the marginal effects are determined by the signs of the coefficient parameters a real data application is provided

explaining the wealth holdings of different cohorts productivity growth and social security in this paper we explore the reasons why different generations accumulate different amounts of wealth we use basic economic theory to propose two indicators of the economic conditions under which households accumulate wealth the first one represents productivity differences across cohorts the aggregate level of gross national product per capita around the time the head of the household entered the labor market the second measure summarizes the changes in social security during the head of household s working life using panel data from the dutch socio economic panel we show that productivity growth can explain all the cohort effects present in income data while productivity growth and the generosity of social security can explain all the cohort effects present in household net worth we also find a limited offset of social security on wealth holdings

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
