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

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

comparative dynamics in a health investment model the method of comparative dynamics fully exploits the inter temporal structure of optimal control models i derive comparative dynamic results in a simplified demand for health model the effect of a change in the depreciation rate on the optimal paths for health capital and investment in health is studied by use of a phase diagram

life cycle consumption and hyperbolic discount functions abstract studies of animal and human behavior suggest that discount functions are approximately hyperbolic ainslie picoeconomics 1992 hyperbolic models explain a wide range of empirical anomalies including 1 missing precautionary savings effects 2 incongruence between the elasticity of intertemporal substitution and the inverse of the coefficient of relative risk aversion 3 consumption discontinuities at retirement 4 variation in patience over the life cycle 5 consumer self reports of undersaving 6 disproportionate retirement accumulation in illiquid assets 7 asset specific marginal propensities to consume and 8 declining national savings rates in developed countries hyperbolic models also provide a new framework for analyzing the welfare gains that come from pro saving policies like social security and tax deferred retirement accounts

optimal aging and death understanding the preston curve does prosperity lead to greater longevity if so what is the strength of the income channel to address these questions we develop a life cycle model in which households are subject to physiological aging in modeling aging we draw on recent research in the elds of biology and medicine the speed of the aging process and thus the time of death are endogenously determined by optimal health investments a calibrated version of the model accounts well for the observed non linear cross country link between longevity and income also known as the preston curve

a monetary policy strategy in good and bad times lessons from the recent past we evaluate the ecb s monetary policy strategy against some of the underlying economic features of the eurozone in normal times and during the financial crisis we show that in the years preceding the crisis the ecb s emphasis on monetary indicators and deliberate avoidance of excessive activism were justified by the underlying macroeconomic conditions that the ecb faced in the eurozone and contributed to avoid more volatile patterns of inflation and economic activity after the collapse of financial intermediation in late 2008 the strategy of the ecb was to adopt several non standard policy measures according to our quantitative evaluation of the impact of the main non standard policies decided in october 2008 and in may 2009 which notably did not include entering commitments regarding the future path of the policy rate such measures have significantly contributed to preserving price stability and forestalling a more disruptive collapse of the macroeconomy stephan fahr roberto motto massimo rostagno frank smets and oreste tristani

the economics of small business finance the roles of private equity and debt markets in the financial growth cycle abstract this article examines the economics of financing small business in private equity and debt markets firms are viewed through a financial growth cycle paradigm in which different capital structures are optimal at different points in the cycle we show the sources of small business finance and how capital structure varies with firm size and age the interconnectedness of small firm finance is discussed along with the impact of the macroeconomic environment we also analyze a number of research and policy issues review the literature and suggest topics for future research

the family as the health producer when spouses are nash bargainers the grossman model is extended to a situation in which the family is regarded as the producer of individual health and spouses are nash bargainers the model has implications for the interaction between family structure income and the stocks of health capital and the bargaining strength of different family members the main insight is that the possibility of divorce affects the distribution of health capital between family members we analyse inter alia the impact on the distribution of health particularly regarding child health of changes in family policies related to the dissolution of the family

flight to quality in banking and economic activity abstract recent explanations of the transmission mechanism of monetary policy have emphasized that riskier lower net worth borrowers are more dependent on bank lending than larger less risky borrowers evidence from the federal reserve s survey on terms of bank lending indicates that the proportion of relatively high quality new loans safe moves countercyclically and granger causes gdp and inventory investment in the aftermath of a tightening of monetary policy the safe variable increases and in turn policy tends to relax once safe has risen

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

measuring benefits from air pollution control where do we stand measuring the benefits from reduced morbidity this paper presents a simple model of preventive health care similar to that of grossman 1972 and uses the model to define what a person would pay for a change in air quality the model assumes that one can build up resistance to acute illnes by increasing his stock of health capital however health capital decays at a rate which depends on air pollution for acute illness willingness to pay as derived from the model is greater than the benefit estimate computed using the damage function approach to illustrate the size of this discrepancy estimates of willingness to pay are computed using data from the michigan panel study of income dynamics the case for government providing information about risks rests secure in the theory of public goods informational scale economies and problems of dissemination conceivably call for a principal agent relationship in which certain types of decisions are delegated to the agency however the setting of standards and prohibitions is too simplistic it seldom recognizes that personal action tends to interact with and partially offset them 8 references

monetary policy and bank lending in the euro area is there a stock market channel or an interest rate channel abstract in this paper i compare a traditional demand oriented model of bank lending with its focus on short term interest rates in the money market to a non traditional capital budgeting model of bank lending based on movements in share valuations for the euro area using non nested hypothesis tests omitted variables tests and granger causality tests i reject the traditional demand oriented model of bank lending and fail to reject the capital budgeting model of bank lending for monetary financial institutions mfi s in the euro area even though europe is a bank based financial system it appears the stock market plays a key role in the lending decisions and allocation of resources in europe one possible policy implication of this research is that the central bank should try and stabilize stock prices in order to achieve their goal of stabilizing bank lending and the economy

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

insurance and imperfect financial markets in grossman s demand for health model a reply to tabata and ohkusa abstract in the article by tabata and ohkusa they show that the insurance system set out in liljas liljas b 1998a the demand for health with uncertainty and insurance journal of health economics 17 153 170 does not have an optimal solution and propose a new formulation it is argued here that even though the new model works mathematically it has a less realistic economic foundation furthermore generalizing the grossman model by making the marginal utility of income variable over time is suggested to be more relevant in the case where there are imperfect financial markets and a simple example is provided overall there seems to be room for further theoretical extensions in the demand for health literature

the meaning of death some simulations of a model of healthy and unhealthy consumption simulations of a model of healthy and unhealthy consumption are used to investigate the impact of various terminal conditions on life span pathways of health related consumption and health a model in which life span and the death stock of health are fixed is compared to versions in which i the death stock of health is freely chosen ii life span is freely chosen iii both the death stock of health and life span are freely chosen the choice of terminal conditions has a striking impact on optimal plans results are discussed with reference to the existing demand for health literature and illustrate the application of iterative processes to determine optimal life span the role played by the marginal value of health capital in determining optimal plans and the importance of checking the second order conditions for the optimal choice of life span

a model of the demand for longevity and the value of life extension we specify a demand function for longevity or quantity of life along with corresponding demand functions for indicators of quality of life and a value of health and life extension function we show that the demand for health must be derived in conjunction with that for longevity and the related consumption plan and that all choices depend on initial individual endowments and terminal conditions our comparative dynamics predictions indicate that optimal health and longevity are increasing functions of endowed wealth rather than necessarily current income that improvements in opportunities to produce health can accentuate the differences between endowed health and attained longevity levels and that the value individuals ascribe to their health may be increasing over a good portion of their life cycle we use this model to analyze observed empirical variations in levels and trends of life expectancy and in exposure to health risks across different population groups

the demand for health with uncertainty and insurance this paper develops michael grossman s demand for health model by letting the depreciation rate depend upon the level of health by letting the incidence and size of illness be uncertain and by investigating how the individual s demand for health would be affected by the introduction of insurance beside the more theoretical results there are also some results with important policy implications when formulating the hypothetical scenario in willingness to pay wtp studies it is important whether the individual believes that the level of health is uncertain or not the existence of insurance could also affect the stated wtp amount taking this into account could therefore explain some of the differences in the wtp for seemingly identical health care programs in different countries or different areas in the same country

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

the effect of inheritance receipt on retirement abstract this paper provides new evidence on how wealth shocks influence retirement behavior economic theory generally posits that leisure is a normal good yet it is difficult to obtain reliable empirical estimates of the wealth effect because wealth is correlated with numerous unobservable characteristics that affect labor supply we use inheritance receipt as a wealth shock and find that it is associated with a significant increase in the probability of retirement especially when the inheritance is unexpected this evidence has important implications for how public policies such as pension or tax reform may influence retirement behavior through the wealth effect

the relationship between education and adult mortality in the united states prior research has uncovered a large and positive correlation between education and health this paper examines whether education has a causal impact on health i follow synthetic cohorts using successive u s censuses to estimate the impact of educational attainment on mortality rates i use compulsory education laws from 1915 to 1939 as instruments for education the results suggest that education has a causal impact on mortality and that this effect is perhaps larger than has been previously estimated in the literature copyright 2005 wiley blackwell

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

estimating the effect of unearned income on labor supply earnings savings and consumption evidence from a survey of lottery players this paper provides empirical evidence about the effect of unearned income on earnings consumption and savings using an original survey of people playing the lottery in massachusetts in the mid 1980 s the effects of the magnitude of lottery prizes on economic behavior are analyzed the critical assumption is that among lottery winners the magnitude of the prize is randomly assigned it is found that unearned income reduces labor earnings with a marginal propensity to consume leisure of approximately 11 percent with larger effects for individuals between 55 and 65 years old after receiving about half their prize individuals saved about 16 percent

optimal choice of health and retirement in a life cycle model abstract we examine within a life cycle model the simultaneous choice of health care and retirement together with consumption health tends to have an impact on retirement through morbidity determining earnings and the disutility of work and through longevity determining the need to accumulate retirement wealth conversely the age of retirement drives the demand for health care through the value of survival and the value of morbidity reductions we characterise the optimal relationship between health expenditure and retirement and apply our model to analyse the effects of moral hazard in the annuity market while moral hazard always induces excessive health investments and an excessive duration of working life it also triggers an excessive level of consumption if the impact of health on the disutility of work is sufficiently large we examine a transfer scheme and mandatory retirement as policies towards curtailing moral hazard numerical analysis illustrates the role of moral hazard in shaping the life cycle allocation

a theory of rational addiction we develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time strong addiction to a good requires a big effect of past consumption of the good on current consumption such powerful complementarities cause some steady states to be unstable they are an important part of our analysis because even small deviations from the consumption at an unstable steady state can lead to large cumulative rises over time in addictive consumption or to rapid falls in consumption to abstention our theory also implies that cold turkey is used to end strong addictions that addicts often go on binges that addicts respond more to permanent than to temporary changes in prices of addictive goods and that anxiety and tensions can precipitate an addiction

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

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

the natalist bias of pollution control for a given technology two ways are available to achieve low polluting emissions reducing production per capita or reducing population size this paper insists on the tension between the former and the latter controlling pollution either through pigovian taxes or through tradable quotas schemes encourages agents to shift away from production to tax free activities such as procreation and leisure this natalist bias will deteriorate the environment further entailing the need to impose ever more stringent pollution rights per person however this will in turn gradually impoverish the successive generations population will tend to increase further and production per capita to decrease as the generations pass one possible solution consists in capping population too

monetary policy in exceptional times this paper describes the way in which the european central bank ecb the federal reserve and the bank of england conducted monetary policy since the beginning of the financial crisis in august 2007 we argue that both quantitative easing and the other non standard measures introduced by central banks that changed the composition of the asset side of their balance sheets so called qualitative easing acted mainly through their effects on interest rates and in particular on money market spreads rather than solely through quantity effects in terms of the money supply we perform a quantitative exercise on the euro area which estimates the effect of the reduction of these spreads to the broader economy michele lenza huw pill and lucrezia reichlin

the legal environment banks and long run economic growth this paper examines the relationship between the legal system and banlding development and traces this connection through to long run rates of per capita gdp growth capital stock growth and productivity growth the data indicate that countries where the legal system 1 emphasizes creditor rights and 2 rigorously enforces contracts have better developed banks than countries where laws do not give a high priority to creditors and where enforcement is lax furtherrnore the exogenous component of banking development the component defined by the legal environment is positively and robustly associated with per capita growth physical capital accumulation and productivity growth this paper addresses two questions first do crosscountry differences in the legal rights of creditors the efficiency of contract enforcement and the origin of the legal system explain cross country differences in the level of banking development second do better developed banks cause faster economic development that is is the component of banking development defined by the legal environment positively associated with long run rates of economic growth capital accumulation and productivity growth examining the relationship between the legal system and banking development is valuable irrespective of issues associated with long run growth first banks may influence the level of income per capita and the magnitude of cyclical fluctuations bernanke and gertler 1989 1990 second many economists stress that understanding the evolution of legal and financial systems is essential for understanding economic development north 1981 engerman and sokoloff 1996 consequently quantitative information on the relationship between the legal environment and banks will improve our understanding of business cycles and the process of economic development furthermore examining the causal links between banks and economic growth has both conceptual and policy implications on the conceptual front a long literature debates the importance of banks in economic development starting as early as bagehot 1873 economists have argued that better banks banks that are better at identifying creditworthy firms mobilizing savings pooling risks and facilitating transactions

economic conditions early in life and individual mortality this paper analyzes the effect of economic conditions early in life on the individual mortality rate later in life using business cycle conditions early in life as an exogenous indicator we have individual data records from dutch registers of birth marriage and death certificates covering an observation window of unprecedented size 1812 2000 these are merged with historical data on macro economic and health indicators we correct for secular changes over time and other mortality determinants we nonparametrically compare those born in a recession to those born in the preceding boom and we estimate duration models where the individual s mortality rate depends on current conditions conditions early in life age individual characteristics including individual socio economic indicators and interaction terms the results indicate a significant negative effect of economic conditions early in life on individual mortality rates at all ages

bank regulation and the credit crunch abstract this study investigates the direct link between regulatory enforcement actions and the shrinkage of bank loans to sectors likely to be bank dependent we partition the shrinkage due to loan supply into the component due to explicit regulatory enforcement actions and that due to a voluntary response by bank management to low capital to asset ratios we find that banks with formal actions shrink at a significantly faster rate than those without even after controlling for differences in capital to asset ratios furthermore much of the reduced lending has been in categories containing primarily loans to bank dependent borrowers

uncertainty and the demand for medical care abstract this paper provides an analysis of the effects of uncertainty on the demand for medical care using a simplified version of grossman s human capital model of the demand for health two types of uncertainty are analysed the uncertainty surrounding the incidence of illness and the uncertainty surrounding the effectiveness of medical care in the first the consumer s basic level of health is assumed to be a random variable in the second the effectiveness of medical care is assumed to be random comparative static results are reported indicating the effects on the demand for medical care of both increases in the means of these distributions and mean preserving spreads of the distributions

comparative dynamic analysis of the full grossman model the paper applies the method of comparative dynamic analysis to the full grossman model for a particular class of solutions it derives the equations implicitly defining the complete trajectories of the endogenous variables relying on the concept of frisch decision functions the impact of any parametric change on an endogenous variable can be decomposed into a direct and an indirect effect the focus of the paper is on marginal changes in the rate of health capital depreciation it also analyses the impact of either initial financial wealth or the initial stock of health capital while the direction of most effects remains ambiguous in the full model the assumption of a zero consumption benefit of health is sufficient to obtain a definite for any direct or indirect effect

modelling the demand for loans to the private sector in the euro area this article studies the determinants of loans to the private sector in the euro area using the johansen methodology the study identifies one cointegrating relationship linking real loans gdp and interest rates this relationship implies that in the long run real loans are positively related to real gdp and negatively to real short term and long term interest rates both the signs and the magnitude of the coefficients suggest that the cointegrating vector describes a long run demand equation the short run dynamics of the demand for euro area real loans is subsequently modelled by means of a vector error correction model vecm a number of specification tests performed on the vecm produce satisfactory results with tests of stability of the model parameters showing no signs of structural breaks during the sample period 1980 1 1999 2 all of this suggests that developments in real loans to the private sector in the euro area can be reasonably explained by the model

retirement and consumption in a life cycle model consumption expenditure declines sharply at the time of retirement for many households but the majority maintain a smooth consumption path a simple life cycle model with uncertainty about the time of retirement can account for this pattern a richer version of the model is calibrated to data from the health and retirement study hrs the median change in consumption expenditure at retirement generated by the model is zero while the mean is negative matching the hrs data however the magnitude of the drop in consumption among households that experience a decline is too small in the model compared to the data

health and other asset holdings despite clear evidence of correlations between financial and medical statuses and decisions most models treat financial and health related choices separately this article bridges this gap by proposing a tractable dynamic framework for the joint determination of optimal consumption portfolio holdings health investment and health insurance we solve for the optimal rules in closed form and capitalize on this tractability to gain a better understanding of the conditions under which separation between financial and health related decisions is sensible and of the pathways through which wealth and health determine allocations welfare and other variables of interest such as expected longevity or the value of health furthermore we show that the model is consistent with the observed patterns of individual allocations and provide realistic estimates of the parameters that confirm the relevance of all the main characteristics of the model

financial aspects of business cycles an analysis of balance sheet adjustments of u s nonfinancial enterprises over the twentieth century this paper formulates and tests a model of asset and financing adjustments of nonfinancial enterprises over the twentieth century asset adjustments change the expected income and operating risk of firms while financing adjustments change financial risk to protect debt and equity investors from a conflict of interest problem an up front contract develops an assignment rule for managing the firm s balance sheet whereby managers make investment decisions that conform to the risk aversion of stockholders and financing decisions that offset changes in operating risk resulting from investment decisions empirical evidence gathered in this paper fails to reject the predictions of the model

health as an unobservable a mimic model of demand for health care abstract this paper develops a model to analyze the demand for health care it differs from current practice in that 1 it deals explicitly with the complex relation between income health health insurance and the demand for health care and 2 health is treated as an unobservable variable we present the maximum likelihood estimates of an eleven equation simultaneous multiple indicator multiple causes mimic model containing two simultaneously determined unobservables and in total nine indicators data used stem from a health care survey among 8000 households in the netherlands the results show among other things that health and permanent income have mutual positive impacts both age and education have important direct and indirect via permanent income effects on health the estimated impact of the availability of health care on individual demand confirms similar results based on aggregated data

borrowing relationships intermediation and the cost of issuing public securities abstract this paper investigates how an established borrowing relationship affects the costs associated with initial public offerings of equity our model illustrates how the existence of a borrowing relationship reduces the ex ante uncertainty about the value of the issuing firm s equity in the secondary market if underpricing is related to uncertainty a borrowing relationship can reduce underpricing empirically we find that other things equal ipos of firms with previously established borrowing relationships are underpriced substantially less than other ipos

employer investments in employee health implications for the family as health producer the model presented in this paper further extends the demand for health model in which the family is the producer of health investments to consider the case in which an employer has incentives for investing in the health of a family member the household and the employer are assumed to interact strategically in the production of health the general insight provided is that the conditions which determine the nature of the relationship between the employer and the employee for instance market conditions production technologies taxes and government regulation will also affect the allocation of health investments and health capital within the family

bank lending and initial public offerings abstract in this paper we test the hypothesis that banking relations are a signal about firm value we argue that bank processing of asymmetric information and external monitoring of corporate activities reduce the ex ante uncertainty of investors about firm value we demonstrate that the existence of bank debt and or lines of credit lowers the expected initial return associated with initial public offerings the empirical results are robust with respect to the inclusion of variables which reflect other mechanisms that can ameliorate ex ante uncertainty our work adds to the body of evidence that supports the hypothesis that intermediaries provide valuable asset services to corporate borrowers

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

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

grossman s missing health threshold we present a generalized solution to grossman s model of health capital 1972 relaxing the widely used assumption that individuals can adjust their health stock instantaneously to an optimal level without adjustment costs the grossman model then predicts the existence of a health threshold above which individuals do not demand medical care our generalized solution addresses a significant criticism the model s prediction that health and medical care are positively related is consistently rejected by the data we suggest structural and reduced form equations to test our generalized solution and contrast the predictions of the model with the empirical literature

long run returns to education does schooling lead to an extended old age while there is no doubt that health is strongly correlated with education whether schooling exerts a causal impact on health is not firmly established we exploit a dutch compulsory schooling law to estimate the causal effect of education on mortality the reform provides a powerful instrument significantly raising years of schooling which in turn has a significant and robust negative effect on mortality for men surviving to age 81 an extra year of schooling is estimated to reduce the probability of dying before the age of 89 by almost three percentage points relative to a baseline of 50 percent

did risk based capital allocate bank credit and cause a credit crunch in the united states this paper examines the reallocation of bank credit from loans to securities in the early 1990s using data on virtually all u s banks from 1979 to 1992 the authors investigate implementation of risk based capital and other regulatory and nonregulatory changes as possible causes of a supply driven credit crunch the main empirical implication of these credit crunch hypotheses that the reallocation of credit would be most associated with low capital high risk banks generally is not consistent with the data much of the reallocation is associated with demand side factors but it is difficult to differentiate cleanly among these factors copyright 1994 by ohio state university press

the family as the health producer when spouses act strategically the grossman model has been extended recently in order to take account of the fact that most people lead their lives in a family using frameworks in which family members respectively a have common preferences and b are nash bargainers these models however do not consider individual incentives for behaving strategically in the model presented in this paper spouses interact strategically both in the production of own health and in the production of health of other family members we analyse inter alia the impact on the distribution of health of changes in family policies such as child allowance and custody rules

explaining and forecasting bank loans good times and crisis abstractthis article aims to develop a parsimonious model to explain and forecast bank loans to nonfinancial companies during calm periods as well as in situations of financial turmoil it focuses on the french context over a period including financial banking and sovereign debt crises theoretical views and intuitions led us to gauge the marginal informational content of a large set of leading indicators in var and vecm models and to investigate potential nonlinearity in credit dynamics in accordance with firms and banks balance sheet effects the growth rate of equity prices appears to be one of the most interesting leading indicator as well as a significant threshold variable for explaining regime switching however it appears difficult to accurately predict the right credit dynamics regimes a simple var model finally performs better

the demand for health some new empirical evidence this paper presents some new estimates of the pure investment and pure consumption models of the demand for health in contrast to previous studies the paper presents parameter estimates of both reduced form and structural demand for health care equations the latter which are obtained by treating health capital as a latent variable in a recursive equation system provide a safer way of checking the consistency of the model s predictions with the data the present analysis of the pure consumption model differs from previous analyses in its recognition of the dependency of the shadow price of initial assets on the entire lifetime profiles of the model s exogenous variables the paper also explores the implications in terms of reliability of parameter estimates of the failure on the part of previous studies to recognize this

the benefits of lending relationships evidence from small business data this paper empirically examines how ties between a firm and its creditors affect the availability and cost of funds to the firm we analyze data collected in a survey of small firms by the small business administration the primary benefit of building close ties with an institutional creditor is that the availability of financing increases we find smaller effects on the price of credit attempts to widen the circle of relationships by borrowing from multiple lenders increases the price and reduces the availability of credit in sum relationships are valuable and appear to operate more through quantities rather than prices

the family as producer of health an extended grossman model deriving a model where each family member is the producer of his own and other family members health shows that the family will not try to equalise marginal benefits and marginal costs of health capital for each family member they will rather invest in health until the rate of marginal consumption benefits equals the rate of marginal net effective costs of health capital the level of compensation in the social insurance system the effective price of care health related information and transfer payments will all affect the production possibility set and therefore the optimal level and distribution of family health

a model of declining health and retirement the declining u s average retirement age has been difficult to reconcile with cross section evidence that poor health is a primary cause of early retirement this paper reconciles those observations by building a grossman type model of investment in health distinguished from its predecessor by a more formal treatment of initial conditions a discontinuous mid life increase in health investment retirement is shown in general to be part of the optimal investment strategy time series productivity increases are shown to lower the optimal retirement age while varying health endowments and depreciation rates are shown to be able to account for cross section retirement age variations

why bank credit policies fluctuate a theory and some evidence in a rational profit maximizing world banks should msdntain a credit policy of lending if and only if borrowers have positive net present value projects why then are changes in credit policy seemingly correlated with changes in the condition of those demanding credit this paper argues that rational bank managers with short horizons will set credit policies that influence and are influenced by other banks and demand side conditions this leads to a theory of low frequency business cycles driven by bank credit policies evidence from the banking crisis in new england in the early 1990s is consistent with the assumptions and predictions of the theory

time preference noncognitive skills and well being across the life course do noncognitive skills encourage healthy behavior a number of prominent diseases are influenced by health behaviors for example it is well known that the decision to smoke comes with considerable risks of developing smoking related ailments such as lung cancer emphysema and heart disease obesity is another health condition that can be costly it is associated with increased risk for diseases such as coronary heart disease and diabetes centers for disease control 2009 nationally it is estimated that about one third of the u s population is obese and estimates suggest that obesity costs society anywhere from 27 to 47 billion in health care expenditures annually centers for disease control 2009 national center for health statistics 2008 research suggests that changing individuals diets and getting them to exercise would help to reduce the prevalence of obesity in society melayne mcinnes and judith shinogle 2009 smoking and obesity provide just two examples of cases in which the nation s burden of disease is influence by behaviors that its citizens engage in because the united states spends a large share of gdp on health care each year understanding the determinants of health behaviors is important as it may allow scholars to identify ways to reduce these costs this paper examines the relationship between individuals health behaviors and the non cognitive skills that individuals possess in the past decade the economics discipline has seen a burst of interest in human capabilities that contribute to labor market productivity beyond the usual foci of attention levels of education and learning by doing the collection of personality traits soft skills incentive enhancing preferences and socio emotional factors that economists are now studying has been loosely grouped together under the heading non cognitive skills 1 while the term may be something of a misnomer because many of the worker attributes that the authors writing in this subfield are interested in require reasoning or cognition the skills of interest have been found to be important determinants of labor market success james heckman jora stixrud and sergio urzua 2006 samuel bowles herbert gintis and melissa osborne 2001 2james heckman 2007 has stated that these socio emotional attributes as non cognitive skills are sometimes called are also likely to affect health behaviors this paper tests this hypothesis it provides a theoretical and an empirical analysis of the connection between socio emotional attributes and the choices that individuals make about health it uses data from a large nationally representative dataset to analyze the relationships

estimating average and local average treatment effects of education when compulsory schooling laws really matter the change to the minimum school leaving age in the united kingdom from 14 to 15 had a powerful and immediate effect that redirected almost half the population of 14 year olds in the mid twentieth century to stay in school for one more year the magnitude of this impact provides a rare opportunity to a estimate local average treatment effects late of high school that come close to population average treatment effects ate and b estimate returns to education using a regression discontinuity design instead of previous estimates that rely on difference in differences methodology or relatively weak instruments comparing late estimates for the united states and canada where very few students were affected by compulsory school laws to the united kingdom estimates provides a test as to whether instrumental variables iv returns to schooling often exceed ordinary least squares ols because gains are high only for small and peculiar groups among the more general population i find instead that the benefits from compulsory schooling are very large whether these laws have an impact on a majority or minority of those exposed

the education health gradient in this paper we determine the role played by early cognitive noncognitive and health endowments we identify the causal effect of education on health and health related behaviors we develop an empirical model of schooling choice and post schooling outcomes where both schooling and the outcomes determined in part by schooling are influenced by measured early family environments and latent capabilities cognitive noncognitive and health we show that family background characteristics and cognitive noncognitive and health endowments developed by age 10 are important determinants of labor market and health disparities at age 30 not properly accounting for personality traits overestimates the importance of cognitive ability in determining adult health selection on factors determined early in life explains more than half of the observed difference by education in poor health depression and obesity education has an important causal effect in explaining differences in many adult outcomes and healthy behaviors we uncover significant gender differences we go beyond the current literature which typically estimates mean effects to compute distributions of treatment effects we show how the health returns to education can vary among individuals who are similar with respect to their observed characteristics and how a mean effect can hide gains and losses for different individuals our research highlights the important role played by the early years in producing health

on adaptation and the demand for health the purpose of this paper is to analyse the impacts of adaptation to failing health this is done by integrating adaptation processes in a grossman type of pure consumption model model simulations show that adaptation affects the health variables by lowering the incentives to invest in health as well as smoothing the optimal health stock path over the life cycle whether or not the risk of mortality is an object of choice has important effects when studying adaptation as well as for the joint development of the health variables

demand for health a generalised grossman model the demand for health and medical care is analysed within a generalised grossman type health investment model its underlying assumptions are shown to differ from those employed earlier in a manner which avoids some of the criticisms levelled at grossman s model the comparative static predictions of the generalised model are examined and it is demonstrated that most previous health investment models are derivable from it also the present model is applicable to a new wider range of problems thus increasing the scope of economic explanations of health behaviour
