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

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

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

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

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

the real effects of liquidity during the financial crisis evidence from automobiles illiquidity in short term credit markets during the financial crisis might have severely curtailed the supply of nonbank consumer credit using a new data set linking every car sold in the united states to the credit supplier involved in each transaction we find that the collapse of the asset backed commercial paper market reduced the financing capacity of such nonbank lenders as captive leasing companies in the automobile industry as a result car sales in counties that traditionally depended on nonbank lenders declined sharply although other lenders increased their supply of credit the net aggregate effect of illiquidity on car sales is large and negative we conclude that the decline in auto sales during the financial crisis was caused in part by a credit supply shock driven by the illiquidity of the most important providers of consumer finance in the auto loan market these results also imply that interventions aimed at arresting illiquidity in short term credit markets might have helped contain the real effects of the crisis

how debt markets have malfunctioned in the crisis the financial crisis that began in 2007 is especially a crisis in debt markets a full understanding of what happened in the financial crisis requires investigation into the plumbing of debt markets during a financial crisis when funds often cannot be raised easily or quickly the fundamental values for certain assets can become separated for a time from market prices with consequences that can echo into the real economy this article will explain in concrete ways how debt markets can malfunction with deleterious consequences for the real economy after a quick overview of debt markets i discuss three areas that are crucial in all debt markets decisions risk capital and risk aversion repo financing and haircuts and counterparty risk in each of these areas feedback effects can arise so that less liquidity and a higher cost for finance can reinforce each other in a contagious spiral i will document the remarkable rise in the premium that investors placed on liquidity during the crisis next i will show how these issues caused debt markets to break down indeed fundamental values and market values seemed to diverge across several markets and products that were far removed from the toxic subprime mortgage assets at the root of the crisis finally i will discuss briefly four steps that the federal reserve took to ease the crisis and how each was geared to a specific systemic fault that arose during the crisis

the speed of employer learning the employer learning literature finds support for statistical discrimination on the basis of schooling how economically relevant statistical discrimination is depends on how fast employers learn about workers productive types this article is the first to estimate the speed of employer learning employers learn quickly initial expectation errors decline by 50 within 3 years this estimate places an upper bound on the contribution of signaling this bound varies with the speed of employer learning and with discount rate for a wide range of parameter values the contribution of signaling to the gains from schooling is less than 25

racial discrimination in the labor market theory and empirics we review theories of race discrimination in the labor market taste based models can generate wage and unemployment duration differentials when combined with either random or directed search even when strong prejudice is not widespread but no existing model explains the unemployment rate differential models of statistical discrimination based on differential observability of productivity across races can explain the pattern and magnitudes of wage differentials but do not address employment and unemployment at their current state of development models of statistical discrimination based on rational stereotypes have little empirical content it is plausible that models combining elements of the search models with statistical discrimination could fit the data we suggest possible avenues to be pursued and comment briefly on the implication of existing theory for public policy jel j15 j31 j64 j71

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

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

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

liquidity and the dynamic pattern of asset price adjustment a global view abstract global liquidity expansion has been very dynamic since 2001 contrary to conventional wisdom high money growth rates have not coincided with a concurrent rise in goods prices at the same time however asset prices have increased sharply significantly outpacing the subdued development in consumer prices we investigate the interactions between money and goods and asset prices at the global level using aggregated data for major oecd countries our var results support the view that different price elasticities on asset and goods markets explain the observed relative price change between asset classes and consumer goods

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

money liquidity and monetary policy in a market based financial system banking and capital market developments are inseparable and funding conditions are closely tied to fluctuations in the leverage of market based financial intermediaries offering a window on liquidity the balance sheet growth of broker dealers provides a sense of the availability of credit contractions of broker dealer balance sheets have tended to precede declines in real economic growth even before the current turmoil for this reason balance sheet quantities of market based financial intermediaries are important macroeconomic state variables for the conduct of monetary policy

fast track is it in the genes the promotion policy of a large japanese firm abstract we study the promotion policy of a large high tech manufacturing japanese firm we find that the company has multiple ports of entry and hires a significant number of employees with previous job experience cohort peer differentiation in promotion starts much earlier than predicted by the common view there are clear signs of fast track effects so that individuals promoted faster earlier on are more likely to be promoted faster later on fast track effects are not in the genes because they survive even after controlling for time invariant individual effects such as innate individual ability the last result is difficult to justify using a pure learning model where ability is time invariant so that a richer learning model that incorporates perhaps human capital considerations is clearly required

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

changes in earnings instability and job loss this paper examines the contribution of job loss or displacement to increasing male earnings instability between 1970 and 1991 earnings instability increased among both displaced and not displaced men so changes associated with job loss cannot fully explain rising instability changes in the incidence and consequences of job loss did however add substantially to growing earnings instability and to the overall variance of earnings there is evidence that displacement substantially raised earnings volatility for several years after job loss that effect combined with increased numbers of recently displaced workers in the 1980s relative to the previous decade contributed to rising overall earnings instability

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

a risk centric model of demand recessions and speculation we provide a continuous time risk centric representation of the new keynesian model which we use to analyze the interactions between asset prices financial speculation and macro economic outcomes when output is determined by aggregate demand in principle interest rate policy is highly effective in dealing with shocks to asset valuations however in practice monetary policy faces a wide range of constraints if these constraints are severe a decline in risky asset valuations generates a demand recession this reduces earnings and generates a negative feedback loop between asset prices and aggregate demand in the recession phase average beliefs matter not only because they affect asset valuations but also because they determine the strength of the amplification mechanism in the ex ante boom phase belief disagreements or heterogeneous asset valuations matter because they induce investors to speculate this speculation exacerbates the crash by reducing high valuation investors wealth when the economy transitions to recession which depresses wealth weighted average beliefs macroprudential policy that restricts speculation in the boom can pareto improve welfare by increasing asset prices and aggregate demand in the recession

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

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

a macroeconomic model with a financial sector this paper studies a macroeconomic model in which financial experts borrow from less productive agents we pursue four sets of results i the economy is prone to instability and occasionally enters volatile episodes as volatility spikes agents precautionary motive increases depressing prices even further log linear approximations fail to capture these non linear effects that can cause economies to be significantly depressed for long periods of time ii endogenous risk during volatile episodes increases asset price correlations iii financial experts impose a negative externality on each other and on the labor sector by not maintaining adequate capital cushion and funding structure iv while risk sharing within the financial sector through securitization and derivatives contracts reduces many inefficiencies it can also amlify systemic risks

job search bargaining and wage dynamics this article constructs and estimates a model of wage bargaining with on the job search to explore three different components of wages general human capital match specific capital and outside options as the workers find better job opportunities the current employer has to compete with outside firms to retain them this between firm competition results in wage growth even when productivity remains the same the model is estimated by a simulated minimum distance estimator and data from the 1979 national longitudinal study of youth the results indicate that the improved value of the outside option raises wages by 14 16 in the first 5 years

worker quality and labor market sorting abstract we test the hypothesis that labor market sorting into outcomes normally associated with wage premia e g incentive pay coverage urban dwelling employment in large firms marriage and union coverage is related to a series of non standard worker quality measures

money creation and the shadow banking system many explanations for the rapid growth of the shadow banking system in the mid2000s focus on money demand this paper asks whether the short term liabilities of the shadow banking system behave like money we rst present a simple model where households demand money services which are supplied by three types of claims deposits treasury bills and asset backed commercial paper abcp the model provides predictions for the price and quantity dynamics of these claims as well as the behavior of the banking system in terms of issuance and the monetary authority in terms of open market operations consistent with the model the empirical evidence suggests that the shadow banking system does respond to money demand

the evolution of wages over the lifecycle insights from intergenerational connections this article uses intergenerational information to improve our understanding of lifecycle wage dynamics i present a simple statistical model that relates the wages of workers at different points in their lifecycle to the earnings of their parents i decompose cross sectional variance of wages into a permanent component related to parental background a permanent component unrelated to parental background and a transitory component data from the panel study of income dynamics psid suggests that intergenerational relationships are stronger when measured later in the lifecycle of the son this implies that the permanent parent related component is increasingly important for wage determination as workers grow older this is not consistent with wage evolution through persistent random shocks rather it is consistent with human capital models and learning models of wage evolution

optimal financial crises empirical evidence suggests that banking panics are related to the business cycle and are not simply the result of sunspots panics occur when depositors perceive that the returns on bank assets are going to be unusually low we develop a simple model of this in this setting bank runs can be first best efficient they allow efficient risk sharing between early and late withdrawing depositors and they allow banks to hold efficient portfolios however if costly runs or markets for risky assets are introduced central bank intervention of the right kind can lead to a pareto improvement in welfare from the earliest times banks have been plagued by the problem of bank runs in which many or all of the bank s depositors attempt to withdraw their funds simultaneously because banks issue liquid liabilities in the form of deposit contracts but invest in illiquid assets in the form of loans they are vulnerable to runs that can lead to closure and liquidation a financial crisis or banking panic occurs when depositors at many or all of the banks in a region or a country attempt to withdraw their funds simultaneously prior to the twentieth century banking panics occurred frequently in europe and the united states panics were generally regarded as a bad thing and the development of central banks to eliminate panics and ensure financial stability has been an important feature of the history of financial systems it has been a long and involved process the first cerntral bank the bank of sweden was established more than 300 years ago the bank of england played an especially important role in the development of effective stabilization policies in the eighteenth and nineteenth centuries by the end of the nineteenth century banking panics had been eliminated in europe the last true panic in england was the overend gurney company crisis of 1866

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

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

financial intermediaries and liquidity creation trading losses associated with information asymmetries can be mitigated by designing securities which split the cash flows of underlying assets these securities which can arise endogenously have values that do not depend on the information known only to informed agents bank debt deposits is an example of this type of liquid security which protect relatively uninformed agents and we provide a rationale for deposit insurance in this content high grade corporate debt and government bonds are other examples implying that a money market mutual fund based payments system may be an alternative to one based on insured bank deposits

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

cyclicality of credit supply firm level evidence abstract we quantify fluctuations in bank loan supply in the time series by studying firms substitution between loans and bonds using firm level data any firm that raises new debt must have a positive demand for external funds conditional on the issuance of new debt we interpret firms switching from loans to bonds as a contraction in bank credit supply we find strong evidence of this substitution at times that are characterized by tight lending standards depressed aggregate lending poor bank performance and tight monetary policy we show that this substitution behavior has strong predictive power for bank borrowing and investments by small firms

the response of interest rates to us and uk quantitative easing we analyse declines in government bond yields following announcements by the federal reserve and the bank of england of plans to buy longer term debt using dynamic term structure models we decompose us and uk yields into expectations about future short term interest rates and term premiums we find that declines in us yields mainly reflected lower expectations of future short term interest rates while declines in uk yields appeared to reflect reduced term premiums thus the relative importance of the signalling and portfolio balance channels of quantitative easing may depend on market institutional structures and central bank communication policies

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

intermediary asset pricing abstract we model the dynamics of risk premia during crises in asset markets where the marginal investor is a financial intermediary intermediaries face an equity capital constraint risk premia r

repo runs evidence from the tri party repo market the repo market has been viewed as a potential source of financial instability since the 2007 to 2009 financial crisis based in part on findings that margins increased sharply in a segment of this market this paper provides evidence suggesting that there was no system wide run on repo using confidential data on tri party repo a major segment of this market we show that the level of margins and the amount of funding were surprisingly stable for most borrowers during the crisis however we also document a sharp decline in the tri party repo funding of lehman in september 2008

do formal salary systems really matter drawing on a single large u s corporation s personnel records for the years 1989 93 the authors analyze an example of the kind of formal salary system used by most large firms they find that this firm s practices were consistent with most of the important conclusions of prior empirical research on internal labor markets the system was highly centralized covering salary levels salary ranges raises and bonuses supervisors had little discretion over pay other than through subjective performance ratings the firm held fairly strictly to the salary rules leading to observable constraints on pay for employees near the top of the salary range these constraints however apparently did not impose important costs on the firm in the form of increased turnover although the system operated without any apparent connection to external factors the authors conclude that it transmitted external labor market forces with little distortion

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

the role of comparative advantage and learning in wage dynamics and intrafirm mobility evidence from germany this article measures the importance of job level assignment based on comparative advantage and learning about workers ability in explaining intrafirm wage and mobility dynamics using survey data from the german socio economic panel the results reveal the importance of nonrandom selection of workers into the rungs of the firm s job ladder measured and unmeasured ability play important roles in workers rank assignment with unmeasured ability being more important at higher levels of the hierarchical job structure there is some evidence of learning effects for workers below age 35 generating mobility between upper and executive levels

promotion signaling gender and turnover new theory and evidence we extend promotion signaling theory to incorporate gender and across firm mobility within and across job levels evidence from worker firm linked finnish panel data supports our theory for some groups controlling for worker performance inferred from performance related pay within firm promotion probabilities are increasing and wage increases from promotion are decreasing in educational attainment for some educational groups with results stronger for first than for subsequent promotions women have lower promotion probabilities than men and a greater sensitivity of promotion probability to educational attainment across firm promotions are rare but bring wage increases exceeding those for internal promotions and across firm lateral moves

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

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

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

performance pay and wage inequality an increasing fraction of jobs in the u s labor market explicitly pay workers for their performance using bonus pay commissions or piece rate contracts using data from the panel study of income dynamics we show that compensation in performance pay jobs is more closely tied to both observed and unobserved productive characteristics of workers than compensation in non performance pay jobs we also find that the return to these productive characteristics increased faster over time in performance pay than in non performance pay jobs we show that this finding is consistent with the view that underlying changes in returns to skill due for instance to technological change induce more firms to offer performance pay contracts and result in more wage inequality among workers who are paid for performance thus performance pay provides a channel through which underlying changes in returns to skill get translated into higher wage inequality we conclude that this channel accounts for 21 of the growth in the variance of male wages between the late 1970s and the early 1990s and for most of the increase in wage inequality above the eightieth percentile over the same period

margin based asset pricing and deviations from the law of one price in a model with heterogeneous risk aversion agents facing margin constraints we show how securities required returns increase in both their betas and their margin requirements negative shocks to fundamentals make margin constraints bind lowering risk free rates and raising sharpe ratios of risky securities especially for high margin securities such a funding liquidity crisis gives rise to bases that is price gaps between securities with identical cash flows but different margins in the time series bases depend on the shadow cost of capital which can be captured through the interest rate spread between collateralized and uncollateralized loans and in the cross section they depend on relative margins we test the model empirically using the credit default swap bond bases and other deviations from the law of one price and use it to evaluate central banks lending facilities jel g01 g12 g13 e44 e50 the paramount role of funding constraints becomes particularly salient during liquidity crises with the one that started in 2007 being an excellent case in point banks unable to fund their operations closed down and the funding problems spread to other investors such as hedge funds that relied on bank funding therefore traditional liquidity providers became forced sellers interest rate spreads increased dramatically treasury rates dropped sharply and central banks stretched their balance sheets to facilitate funding these funding problems had significant asset pricing effects the most extreme example being the failure of the law of one price loop securities with nearly

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

the effectiveness of alternative monetary policy tools in a zero lower bound environment this paper reviews alternative options for monetary policy when the shortterm interest rate is at the zero lower bound and develops new empirical estimates of the effects of the maturity structure of publicly held debt on the term structure of interest rates we use a model of risk averse arbitrageurs to develop measures of how the maturity structure of debt held by the public might affect the pricing of level slope and curvature term structure risk we find that these treasury factors historically were quite helpful for predicting both yields and excess returns over 1990 2007 the historical correlations are consistent with the claim that if in december 2006 the fed were to have sold off all its treasury holdings of less than 1 year maturity about 400 billion and use the proceeds to retire treasury debt from the long end this might have resulted in a 14 basis point drop in the 10 year rate and an 11 basis point increase in the 6 month rate we also develop a description of how the dynamic behavior of the term structure of interest rates changed after hitting the zero lower bound in 2009 our estimates imply that at the zero lower bound such a maturity swap would have the same effects as buying 400 billion in long term maturities outright with newly created reserves and could reduce the 10 year rate by 13 basis points without raising short term yields

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

the effectiveness of the fed s quantitative easing policy new evidence based on international interest rate differentials abstract this paper explores the effects of non standard monetary policies on international yield relationships we first document that long term rates followed a common global downward trend that had already manifested itself prior to the financial crisis the bond buying operations commonly dubbed quantitative easing qe of the us federal reserve did not disturb this global co movement i e the global downward trend in interest rates we model the relationship between usd and euro riskless long term interest rates using a cointegrated vector autoregressive model cvar employing recursive estimation methods we find no evidence that qe1 or the qe episodes destabilized the transatlantic interest rate relationship nor the relationship between interest rates and the us dollar exchange rate a robustness test using a vector autoregressive model var with interest rates inflation rates and output differentials for 11 countries relative to us yielded the same result there is thus little evidence that central bank bond buying in the us had an independent distinct impact on us interest rates

what does monetary policy do to long term interest rates at the zero lower bound this article uses a structural var with daily data to identify the effects of monetary policy shocks on various longer term interest rates since the federal funds rate has been stuck at the zero lower bound the var is identified using the assumption that monetary policy shocks are heteroskedastic monetary policy shocks have especially high variance on days of fomc meetings and certain speeches while there is otherwise nothing unusual about these days a complementary high frequency event study approach is also used i find that stimulative monetary policy shocks lower treasury and corporate bond yields but the effects die off fairly fast

have we underestimated the likelihood and severity of zero lower bound events prior to the financial crisis most economists probably did not view the zero lower bound zlb as a major problem for central banks using a range of structural and statistical models we find that previous research understated the zlb threat by ignoring uncertainty about model parameters and latent variables focusing too much on the great moderation experience and relying on structural models whose dynamics cannot generate sustained zlb episodes our analysis also suggests that the federal reserve s asset purchases while materially improving macroeconomic conditions did not prevent the zlb constraint from having first order adverse effects on real activity and inflation

on the wage growth of immigrants israel 1990 2000 this paper develops a descriptive methodology for the analysis of wage growth of immigrants that is based on human capital theory the sources of the wage growth are 1 the rise of the return to imported human capital 2 the impact of accumulated experience in the host country and 3 the mobility up the occupational ladder in the host country the model implies a nonlinear wage function that includes interactions between imported skills and local wage growth using data on native israelis and immigrants from the former soviet union of israel we estimate wage equations jointly for the two groups we find that upon arrival immigrants receive non return for imported skills in the ten years following arrival wages of highly skilled immigrants grow at 8 percent a year rising prices of skills occupational transitions accumulated experience in israel and an economy wide rise in wages account for 3 4 1 1 1 5 and 1 5 percent each in the long run the return for schooling converges to 0 027 substantially below the 0 069 return for natives we do not reject the hypothesis that the return for experience converges to that of natives and that immigrants receive a higher return for their unmeasured skills we find that there is some downgrading in the occupational distribution of immigrants relative to that of natives moreover the average wages of immigrants approach but do not converge to the wages of comparable natives the main reason for this is the low return to their imported skills jel j24 j31 j60

assessing the economy wide effects of quantitative easing this article examines the macroeconomic impact of the first round of quantitative easing qe by the bank of england we attempt to quantify the effects of these purchases by focusing on the impact of lower long term interest rates on the wider economy we use three different models to estimate the impact of qe on output and inflation a large bayesian vector autoregression var a change point structural var and a time varying parameter var our estimates suggest that qe may have had a peak effect on the level of real gdp of around and a peak effect on annual cpi inflation of about points
