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

consumer debt stress changes in household debt and the great recession this research examines psychological debt stress and changes in household debt holdings for consumers during the great recession using data from a monthly national u s household survey covering the period 2006 through 2012 debt stress measures in the population rose by over 50 at the bottom of the recession determining relative stress for eight different types of household debt we find that noncollateralized debts are more stressful than collateralized debt and that during the recession the composition of debt shifted away from collateralized debt and toward noncollateralized our empirical results show that women and hispanics experienced higher measured levels of stress jel d12 d18 i introduction in the latter part of the twentieth century household debt began to rise to high levels in the united states accompanying this there was an upsurge in reports concerning psychological debt stress coming from financial and family counselors health care professionals employers and others these reports pointed to a wide range of health family and job problems for americans arising from this increase in debt after 2007 events in the housing market marked the onset of the great recession and financial crisis many households faced declining home prices and foreclosure as well as changes in other asset values and incomes there was a general tightening of credit and changes in some lending practices by banks here we seek to add additional understanding to changes in consumer debt stress 1 during the great recession by relating them to changes in eight different types of debt holdings during this period we use data covering 2006 through 2012 from the consumer finance monthly survey cfm a national random telephone survey of household finances taken on a monthly basis from a cross

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

some empirical evidence on the effects of shocks to monetary policy on exchange rates this paper investigates the effects of shocks to u s monetary policy on exchange rates we consider three measures of these shocks orthogonalized shocks to the federal funds rate orthogonalized shocks to the ratio of nonborrowed to total reserves and changes in the romer and romer index of monetary policy in sharp contrast to the literature we find substantial evidence of a link between monetary policy and exchange rates specifically according to our results a contractionary shock to u s monetary policy leads to i persistent significant appreciations in u s nominal and real exchange rates and ii significant persistent deviations from uncovered interest rate parity in favor of u s interest rates

the effect of concealed weapons laws an extreme bound analysis i introduction in a recent paper lott and mustard 1997 provide evidence on the relationship between concealed handgun laws often called right to carry or shall issue laws and crime they examine 16 years 1977 1992 of county level crime data from the fbi s uniform crime reports ucr and compare crime rates before and after the introduction of right to carry laws controlling for demographic factors and county level arrest rates they find that introducing right to carry laws resulted in significant reductions in the violent crimes of murder rape aggravated assault and robbery and increases in some property crimes such as burglary larceny and auto theft the latter increase is attributed to a substitution effect suggesting that potential criminals will at the margin switch from violent crimes that have now become more risky to them to property crimes where the probability of encountering an armed victim is much lower comparing these two effects coupled with a slight increase in accidental gunshots from individuals owning concealed handguns lott and mustard conclude that the social benefits of these laws exceed their costs economists who present one set of empirical results are always vulnerable to criticism that they could have selected another group of right hand side variables or modeled them in a different way lott and mustard s analysis has been criticized by black and nagin 1998 who re examine the data set choosing a different set of controls and a different model and reach different conclusions about the effects of the right to carry laws uncertainty about what to control for and how to do it has been called model uncertainty by leamer 1983 who suggests estimating the size of model uncertainty by testing the sensitivity of the particular results to many different possible model specifications this methodology is called extreme bound analysis in this paper we report extreme bounds from nearly 20 000 estimated regressions that vary the modeling choices made by lott and mustard we find support for the deterrence result from a broad set of specifications in particular we find strong support for the hypothesis that the right to carry laws are associated with a decrease in the trend in violent crime rates we do not find much support for a substitution effect into property crimes in what follows we first describe some econometric issues related to the problem of estimating the effect of the right to carry laws on crime rates we then report our extreme bound analysis and offer concluding remarks ii extreme bound analysis although behavioral theories can provide general guidance about the kinds of factors that should influence the crime rate they do not specifically determine which variables should be included in a regression analysis in addition conflicting theories typically suggest alternate model specifications in the context of crime rates for example we might expect higher crime rates in counties with higher unemployment and a larger percentage of young men age 18 30 following convention we call this a supply effect nagin 1978 however it is also possible that higher unemployment leads to the passage of right to carry laws or that right to carry laws are less likely to be enacted in areas with high percentages of young men age 18 30 we call this a demand effect omitted or unobserved demand or supply variables may induce a spurious correlation between the adoption of the right to carry laws and crime rates that has nothing to do with the supply of crime leamer 1983 suggests a formal specification search or extreme bound analysis to estimate the size of such model uncertainty surrounding certain regression results for example by including different right hand side variables in a supply of crime equation for murder leamer estimates an extreme bound interval for the deterrent effect of capital punishment that ranges from 29 to 12 murders prevented for every execution

the most dangerous idea in federal reserve history monetary policy doesn t matter the hundredth anniversary of the founding of the federal reserve is a natural time to reflect on the record of us monetary policy it is widely agreed that this record is far from perfect and that there have been some major failures of monetary policy over the past century our thesis is that overly pessimistic views about the power of monetary policy have been a critical source of these failures there is little doubt that the opposite problem an overinflated belief in the power of monetary policy has also contributed to important policy errors most famously policymakers in the mid 1960s believed that they faced a longrun inflation unemployment trade off and thus that monetary policy could move the economy to a sustained path of very low unemployment and low inflation this belief led them to pursue highly expansionary policy starting the economy down the road to the inflation of the 1970s for example romer and romer 2002 and primiceri 2006 the record of such errors has led some to argue that perhaps the most impor tant attribute of a successful central banker is humility for example booth 2012 in this paper we present evidence that an unduly pessimistic view of what monetary policy can accomplish has been a more impor tant source of policy errors and poor outcomes over the history of the federal reserve at various times in the 1930s faced with the great depression federal reserve officials believed that the power of monetary policy to combat the downturn or stimulate recovery was minimal in

the phillips curve back to the 60s abstract this paper reexamines the behavior of inflation and unemployment and reaches four conclusions 1 the u s phillips curve is alive and well at least as well as in the past 2 inflation expectations however have become steadily more anchored 3 the slope of the curve has substantially declined but the decline dates back to the 1980s rather than to the crisis 4 the standard error of the residual in the relation is large especially in comparison to the low level of inflation each of the four conclusions presents challenges for the conduct of monetary policy

the deterrent effect of capital punishment evidence from a judicial experiment i introduction the contemporary debate over capital punishment involves a number of important arguments based on either moral principles or social welfare considerations the primary social welfare issue viewed as the most important single consideration for both sides in the death penalty controversy is whether capital punishment deters capital crimes see for example zimring and hawkins 1986 this issue is also of great interest to several states that are currently considering a change in their death penalty laws 1 psychologists and criminologists studied the death penalty initially and reported no deterrent effect see for example sellin 1959 and eysenck 1970 economists joined the debate later with ehrlich s 1975 and 1977 studies that report a significant deterrent effect applying regression analysis to u s aggregate data for 1933 69 and state level data for 1940 and 1950 ensuing studies use either ehrlich s data with different regression specifications different regressors functional form or endogenous variables or postmoratorium data with a variant of ehrlich s regression model results range from a substantial deterrent effect to no effect or a small adverse effect 2 this study uses a new approach to advance the deterrence literature we exploit an important characteristic that other studies have not considered the experimental nature of the moratorium that the supreme court imposed on executions during the 1970s the moratorium can be viewed as an exogenously imposed judicial experiment the experiment s effect on murder rates provides evidence about the deterrent effect of capital punishment we compare the murder rate for each state immediately before and after it suspended or reinstated the death penalty many factors that affect crime for example law enforcement judicial demographic and economic variables change only slightly over a short period of time therefore changes in a state s murder rate quickly following a change in its death penalty law can be attributed to the legal change also there are considerable cross state variations in the timing and duration of the moratorium that began and ended in different years in different states ranging from four to thirty years see tables 1 and 2 3 these variations can strengthen our comparison based inference because observing similar changes in murder rates immediately after the same legal change in different years and in various states provides compelling evidence of the moratorium s effect on murder moreover our analysis benefits from the experiences of the states that suspended and reinstated their death penalty statutes several times 4 for states that experience similar murder rate changes after suspensions or reinstatements in different crime economic and demographic environments the contribution of the legal change to murder is paramount we supplement the before and after comparisons with time series and panel data regression analyses unlike most existing studies we use both pre and postmoratorium data the regressions disentangle the effect of having death penalty laws on murder from the effect of actual executions on murder basing our inference on two different approaches allows us to corroborate our findings and also detract from the modeling concerns voiced at previous studies that use only regression analysis we also apply a battery of tests to examine the robustness of the findings these include regression sensitivity checks with 89 additional regression equations that differ from our base models in regressors functional form data and estimation method in addition we test whether the moratorium has an effect on property crimes that are not punishable by death if the relationship between the moratorium and these crimes is similar to the relationship between the moratorium and murder then we should suspect that murder rate changes are the result of broader trends in criminal behavior affecting all crimes

measurement matters recent results from monetary economics reexamined inferences about the effects of money on economic activity may depend importantly on the choice of a monetary index because simple sum aggregates cannot internalize pure substitution effects this hypothesis is investigated by replicating five recent studies that have challenged an aspect of the conventional wisdom about the effects of money on aggregate activity in four of the five cases the qualitative inference in the original study is reversed when a simple sum monetary aggregate is replaced by a divisia index of the same asset collection the results are mixed in the fifth case

how fragile are fragile inferences a re evaluation of the deterrent effect of capital punishment extreme bounds analysis attempts to measure the effects of the uncertainty in the specification of the explanatory variables in a regression model on the estimated coefficients of interest standard errors for the stochastic extreme bounds are computed using the bootstrap technique state by state cross section data are used to study the deterrent effect of capital punishment in the united states in 1950 the bootstrap standard errors are sufficiently large for some bounds to suggest caution in the interpretation of the empirical results regarding the fragility of inferences for the deterrent effect of capital punishment copyright 1989 by mit press

the identification of monetary policy disturbances explaining the liquidity puzzle abstract this paper examines recent work on the identification of monetary policy disturbances its main finding is that the empirical anomalies found in the literature reflect a failure to properly address the federal reserve s policy of accommodating reserve demand shocks a new method of identifying monetary policy using nonborrowed reserves is proposed using this specification policy has a strong persistent liquidity effect regardless of subsample policy granger causes output even in the presence of interest rates explaining approximately 49 of the variance in output at a two year horizon and the residual explanatory power of interest rates for output is negligible

rethinking the liquidity puzzle application of a new measure of the economic money stock historically attempts to solve the liquidity puzzle have focused on narrowly defined monetary aggregates such as non borrowed reserves the monetary base or m1 many of these efforts have failed to find a short term negative correlation between interest rates and monetary policy innovations more recent research uses sophisticated macroeconomic and econometric modeling however little research has investigated the role measurement error plays in the liquidity puzzle since in nearly every case work investigating the liquidity puzzle has used one of the official monetary aggregates which have been shown to exhibit significant measurement error this paper examines the role that measurement error plays in the liquidity puzzle by i providing a theoretical framework explaining how the official simple sum methodology can lead to a liquidity puzzle and ii testing for the liquidity effect by estimating an unrestricted var

dead man walking an empirical reassessment of the deterrent effect of capital punishment using the bounds testing approach to cointegration this paper empirically estimates a murder supply equation for the united states from 1965 to 2001 within a cointegration and error correction framework our findings suggest that any support for the deterrence hypothesis is sensitive to the inclusion of variables for the effects of guns and other crimes in the long run we find that real income and the conditional probability of receiving the death sentence are the main factors explaining variations in the homicide rate in the short run the aggravated assault rate and robbery rate are the most important determinants of the homicide rate

income inequality and health status in the united states evidence from the current population survey several recent studies have identified an association between income inequality and aggregate health outcomes this has been taken to be evidence that inequality is detrimental to individual health we use data from the 1995 99 march current population survey to examine the effect of income inequality on individual health status for both the general population and those individuals in poverty we find no consistent association between income inequality and individual health status our results contradict recent claims that the psychosocial effects of income inequality have dramatic consequences for individual health outcomes

interpreting the macroeconomic time series facts the effects of monetary policy existing theory and evidence on the effects of monetary policy are reviewed substantial room for disagreement among economists remains new evidence based on multivariate time series studies of several countries is presented while certain patterns in the data consistent with effective monetary policy are strikingly similar across countries others particularly the tendency of interest rate increases to predict high inflation are harder to reconcile with effective monetary policy

exploring the health wealth nexus the causal links between health and economic resources have long concerned social scientists we use four waves of data from the panel study of income dynamics psid to analyze the impact of wealth upon an individual s health status the difficulty in approaching this task that has bedeviled previous studies is that wealth may be endogenous a priori it is just as likely that changes in health affect wealth as vice versa we argue that inheritance is a suitable instrument for the change in wealth and implement a straightforward instrumental variables strategy to deal with this problem our results suggest that the causal relationship running from wealth to health may not be as strong as first appears in the data wealth exerts a positive and statistically significant effect on health status but it is very small in magnitude instrumental variables estimation leaves the point estimate approximately the same but renders it insignificantly different from zero and even when the point estimate is increased by twice its standard error s e the quantitative effect is small we conclude that the wealth health connection is not driven by short run changes in wealth

government debt and the demand for money an extreme bound analysis m keivan deravi charles e hegji and h dean moberly the article provides evidence that there is a relationship between government debt and interest rates via the demand for money this relationship is examined through the wealth effect of government debt on money demand and the robustness of the results is tested by the use of extreme bound analysis in addition to standard econometric techniques we find that ols regression shows government debt affecting the demand for money positively implying that federal government debt is net wealth in addition the extreme bound analysis shows that the estimates of the government debt coefficient are robust under alternative specifications of the goldfeld model i introduction this paper studies the relationship between government debt and interest rates the approach used in this paper differs from previous studies in two ways first this relationship is examined through the wealth effect of government debt on the demand for money second the robustness of the results is tested by use of extreme bound analysis as an alternative to standard econometric techniques theoretically there is no clear cut consensus as to whether or not government debt should be net wealth the argument used most often is that government debt will be net wealth if future tax liabilities to service the debt are for the aggregate economy only partially discounted two explanations for this partial discounting are offered first in dealing with finite lived individuals thompson 1967 assumes that the average remaining lifetime of current taxpayers is shorter than for future interest payments on the federal debt in this situation the net present value of a stream of equal interest payments and taxes will be positive as a counter argument barro 1974 has shown that current generations can act effectively as if they are infinite lived when they are linked to future generations through a series of pairwise transfers of wealth here the realization by current generations that tax liabilities will be left to future generations extends the lifetime of the relevant stream of tax liabilities for debt service government debt is then wealth neutral mundell 1971 provides a second reason for partial discounting by assuming that capital markets are imperfect and that the relevant discount rate for tax liabilities is higher than the rate for interest payments these discount rates are respectively thought of as applying to high risk of loan default and low risk of loan default individuals this difference in discount rates creates a positive wealth effect since under mundell s assumptions government debt held by taxpayers involves a loan from low discount rate to high discount rate individuals as barro 1974 has again countered this wealth effect will exist only to the extent that the government is more efficient at providing such a loan than the private sector finally barro 1974 kormendi 1983 and later aschauer 1985 advance an argument as to why government debt might be negative net wealth suppose there is considerable uncertainty about the intertemporal and cross sectional burden of the future tax liability necessary to service the debt in this case the certainty equivalent value of these future taxes might exceed the certainty equivalent value of the future income stream of the debt so that government debt would be negative net wealth the majority of the empirical studies of the net wealth induced linkage between government debt and interest rates have attempted to measure this relationship using consumption functions if privately owned government debt is net wealth the wealth effect of this debt working through a keynesian consumption function will be positive so that increased government borrowing will result in increased current consumption and interest rates several studies have assessed the relationship between government borrowing and consumption or interest rates via this mechanism

the effects of health events on the economic status of married couples this paper uses measures of exogenous health shocks to identify the different channels through which changes in health conditions affect income wealth and consumption behavior the results indicate that serious health conditions have strong effects on household wealth but that the effects for women are larger and more significant than the effects for men the source of the asymmetry arises from the fact that general living expenses increase when wives become seriously ill while for husbands health shocks do not affect these expenditures

the credibility revolution in empirical economics how better research design is taking the con out of econometrics since edward leamer s memorable 1983 paper let s take the con out of econometrics empirical microeconomics has experienced a credibility revolution while leamer s suggested remedy sensitivity analysis has played a role in this we argue that the primary engine driving improvement has been a focus on the quality of empirical research designs the advantages of a good research design are perhaps most easily apparent in research using random assignment we begin with an overview of leamer s 1983 critique and his proposed remedies we then turn to the key factors we see contributing to improved empirical work including the availability of more and better data along with advances in theoretical econometric understanding but especially the fact that research design has moved front and center in much of empirical micro we offer a brief digression into macroeconomics and industrial organization where progress by our lights is less dramatic although there is work in both fields that we find encouraging finally we discuss the view that the design pendulum has swung too far critics of design driven studies argue that in pursuit of clean and credible research designs researchers seek good answers instead of good questions we briefly respond to this concern which worries us little

monetary policy rules based on real time data this paper examines the magnitude of informational problems associated with the implementation and interpretation of simple monetary policy rules using taylor s rule as an example i demonstrate that real time policy recommendations differ considerably from those obtained with ex post revised data further estimated policy reaction functions based on ex post revised data provide misleading descriptions of historical policy and obscure the behavior suggested by information available to the federal reserve in real time these results indicate that reliance on the information actually available to policy makers in real time is essential for the analysis of monetary policy rules

eating drinking smoking and testing the lifecycle hypothesis this paper presents some evidence on expenditure patterns over the lifecycle that has a direct bearing on the question of whether households are significantly credit constrained our particular test looks at the consumption of food alcoholic beverages and tobacco to see whether the consumption of the latter two goods falls as couples have children the latter usually involves a decrease in household current income and an increase in needs if households are not credit constrained they should maintain their consumption of alcoholic beverages and tobacco we find no significant decrease in the consumption of these goods

the dynamic impacts of monetary policy an exercise in tentative identification it is currently popular to identify monetary policy shocks with innovations in some measure of reserves or in the federal funds rate these assumptions about the interest elasticity of the supply of or demand for reserves imply monetary policy shocks that produce dynamic responses of macroeconomic variables that are anomalous relative to traditional monetary analyses this paper tentatively identifies supply and demand shocks in the markets for reserves and m2 for the 1980s and contrasts them with results for the 1970s in the later period identified monetary policy shocks have dynamic impacts that are fully consistent with traditional analyses

in search of the liquidity effect abstract a short run negative relationship between monetary aggregates and interest rates the liquidity effect is central to discussions of monetary policy this paper searches for this empirical relationship we investigate whether the characterization of the liquidity effect is sensitive to i changes in sample period ii conditioning the correlations on past information iii assuming money growth is exogenous and iv treating monetary changes as anticipated or unanticipated the correlations change substantially in each case we conclude that the traditional analysis and modern models which rely completely on demand side behavior cannot explain the observed correlations a successful characterization of the liquidity effect requires identification of both private and policy behavior

emergent extremism in a multi agent model of religious clubs i introduction religious extremism is as old as religion itself but the tendency to promote militancy and terrorism from within extremist religions appears to be much more common now than in times past juergensmeyer 2001 stern 2003 wiktorowicz 2005 1 today s terrorists routinely frame their objectives in religious terms and organize their activities within religious movements this shift is not due to increased militancy within religion as a whole not even within the stricter subset of religious groups commonly labeled sectarian or fundamentalist bromley and melton 2002 marty and appleby 1995 rather groups with militant objectives are increasingly leveraging the latent potential for violence within extremist religion krueger and maleckova 2003 and krueger 2007 have shown that contrary to popular hypotheses regarding the salience of poverty and education it is instead institutional conditions such as civil liberties that contribute to the origination of terrorists within a country religious extremism has been shown to be a potentially powerful input into the production of terrorism berman 2004 2 and the origination of terrorists has been empirically connected to civil liberties we seek to complete the triangle and connect religious extremism to social conditions in an extension of existing theory and test the predictions of the model in an empirical context with an eye toward civil liberties this paper extends previous models of religious clubs to better account for observed patterns of extremism across different settings and test policies most likely to reduce the appeal of extremism economists at first blush should have trouble explaining the survival of groups that demand large sacrifices from their members successful religious groups however routinely impose all sorts of apparently unproductive costs on their members iannaccone 1992 introduced a formal model of religious clubs within which apparently irrational sacrifice and stigma enhances the individual and collective utility his model demonstrated the feasibility of extremist groups but does less to explain the relative prevalence of extremism across time and place further the original model allows for only corner solutions and as such the viability of extreme groups is indistinguishable from the viability of the more moderate groups they must compete with for members in the religious marketplace in section ii we revisit analyze and extend the club model of religion we push the analysis of the original model exploring sacrifice substitutability of club and private goods and their relationships to member commitment and the viability of extremist groups in this preliminary analysis we illustrate not only the potential insights of the club theory of religion into the strength and viability of extremist groups but also the limitations inherent to the representative agent model we proceed by extending the model in a multi agent ma computational framework this framework permits us to analyze the distributions of agents and clubs that make up a religious economy the computational nature of the model is critical because it allows for sufficient heterogeneity of agents and clubs and given this heterogeneity agent decision making absent closed form solutions via nash equilibria extremists groups emerge as just one segment the high cost tail of a distribution of religious clubs that range across the full spectrum of potential group imposed sacrifice and stigma extremism is identifiable and comparable in the model because it exists within a full spectrum of clubs by varying the parameters of the model that control the distribution of secular wages across agents and the degree of substitutability between religious and secular commodities we can better explain where and when religious extremism is most popular its strength relative to more moderate groups and which economic policies reduce its prevalence

a model of monetary policy shocks for financial crises and normal conditions in their classic 1999 paper monetary policy shocks what have we learned and to what end christiano eichenbaum and evans cee investigate one of the most widely used methods for identifying monetary policy shocks of its time unfortunately their approach is no longer viable at least not in its original form a major problem stems from the recent behavior of two key variables in their model the fed funds rate and non borrowed reserves we develop a new identification scheme that remedies these diculties but maintains the basic cee framework our empirical specification is motivated by a standard new keynesian dsge model augmented by a simple financial structure the model provides theoretical support for variables we use in place of certain variables that were used in the classic var approach outlined in cee one significant innovation is our use of divisia m4 the broadest monetary aggregate currently available for the united states as the policy indicator variable we obtain four major empirical results that support the use of a properly measured broad monetary aggregate as the policy variable first policy shocks have significant eects on output and on the price level even when an interest rate is included in our model contradicting the new keynesian argument that monetary aggregates are redundant second we develop a model that is not subject to the output price or liquidity puzzles common to this literature contradicting the view that using the interest rate as the policy indicator generally yields more reasonable responses than a monetary aggregate third during normal conditions policy shocks from our divisia based model have similar eects on variables to those found in the fed funds model of monetary policy and where there are dierences our model with divisia m4 obtains results that are more consistent with standard economic theory fourth our preferred specification produces plausible responses to a monetary policy shock in samples that include or exclude the recent financial crisis

what will take the con out of econometrics the paper begins with the question of whether leamer s extreme bounds analysis eba really does take the con out of econometrics by analytically demonstrating that the extreme bounds are simply functions of the f statistic for the deletion of variables from a regression we conclude that the information provided by eba represents no advance over that available from traditional methods furthermore there is a degree of arbitrariness in eba which exactly parallels the selective reporting of regressions it was designed to supplant the last part of the paper attempts a positive response to its title by following a well defined series of modelling steps we maintain that cooley and le roy s eba derived conclusions concerning the interest elasticity of money demand owe more to a faulty methodology than to the data this abstract was borrowed from another version of this item

five facts about prices a reevaluation of menu cost models are price decreases 3 the frequency of price increases covaries strongly with inflation whereas the frequency of price decreases and the size of price increases and price decreases do not 4 the frequency of price change is highly seasonal it is highest in the first quarter and then declines 5 we find no evidence of upwardsloping hazard functions of price changes for individual products we show that the first second and third facts are consistent with a benchmark menu cost model whereas the fourth and fifth facts are not

the evolution of medical spending risk how has the economic risk of health spending changed over time for u s households we describe trends in aggregate health spending in the united states and how private insurance markets and public insurance programs have changed over time we then present evidence from consumer expenditure survey microdata on how the distribution of household spending on health that is out of pocket payments for medical care plus the household s share of health insurance premiums has changed over time this distribution has shifted up over time households spend more on medical care and insurance than they used to but for the purposes of measuring change in risk it is not the mean but the dispersion of this distribution that is of interest we consider two measures of dispersion that serve as proxies for household risk the standard deviation of the distribution of household health spending and the ratio of the 90th percentile of spending to the median the so called 90 50 gap we find surprisingly that neither has increased despite the rapid rise in aggregate health spending this conclusion holds true for broad subgroups of the population for example the nonelderly as a group but not for some narrowly defined subgroups for example low income families with children we next consider how much risk households should face from the perspective of economic efficiency household risk may not have changed much over the past several decades but do we have any evidence that this level represents either too much or too little risk finally we discuss implications for public policy in particular for current debates over expanding health insurance coverage to the uninsured

optimal interest rate smoothing this paper considers the desirability of the observed tendency of central banks to adjust interest rates only gradually in response to changes in economic conditions it shows in the context of a simple model of optimizing private sector behaviour that assignment of an interest rate smoothing objective to the central bank may be desirable even when reduction of the magnitude of interest rate changes is not a social objective in itself this is because a response of policy to irrelevant lagged variables may be desirable owing to the way it steers private sector expectations of future policy

sensitivity analyses of the deterrence hypothesis let s keep the econ in econometrics abstract leamer and mcmanus applied extreme bound analysis eba in an empirical study of the deterrent effects of capital punishment and other penalties their analysis has questioned the validity of the deterrence hypothesis the thrust of our paper is twofold first by applying eba to well known econometric models of demand production and human capital investment our analysis exposes and illustrates the inherent flaws of eba as a method of deriving valid inferences about model specification second since the analysis shows leamer and mcmanus s inferences about deterrence to be based on a flawed methodology we offer an alternative theory based sensitivity analysis of estimated deterrent effects using similar data our analysis supports the deterrence hypothesis more generally it emphasizes the indispensable role of theory in guiding sensitivity analyses of model specification

money s role in the monetary business cycle a small structural model of the monetary business cycle implies that real money balances enter into a correctly specified forward looking is curve if and only if they enter into a correctly specified forward looking phillips curve the model also implies that empirical measures of real balances must be adjusted for shifts in money demand to accurately isolate and quantify the dynamic effects of money on output and inflation maximum likelihood estimates of the modelos parameters take both these considerations into account but still suggest that money plays a minimal role in the monetary business cycle

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

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

toward a bias corrected currency equivalent index abstract the currency equivalent index measures the discounted economic capital stock of money producing the monetary service flow but does so under assumptions that cause downward bias we propose an extension that will correct for a significant amount of this bias

crime punishment and the market for offenses crime is a subject of intense emotions conflicting ideologies however economists have generally explained it as a reflection of individual choice and equilibrating market forces two major themes of the literature are outlined the evolution of a market model to explain the diversity of crime across time and space and the debate about the usefulness of positive versus negative incentives systematic analyses generally indicate that crime is affected on the margin by both positive and negative incentives there are serious limitations to the effectiveness of incapacitation and rehabilitation and optimal enforcement strategies involve trade offs between narrow efficiency and equity considerations

labor supply and marital separation panel data are used to estimate the effect of marital separation on labor supply female labor supply increases substantially and male labor supply declines marginally lending support to the theory of specialization within the household the most interesting finding is that women began to increase their labor supply well before the actualsplit occurs suggesting either that shocks to labor supply change divorce probabilities or that women with a higher likelihood of divorcework more this argument is pursued by constructing and estimating a simultaneous model of labor supply and divorce risk copyright 1986 by american economic association

from the econometrics of capital punishment to the capital punishment of econometrics on the use and abuse of sensitivity analysis the academic debate over the deterrent effect of capital punishment has intensified again with a major policy outcome at stake about two dozen empirical studies have recently emerged that explore the issue donohue and wolfers 2005 claim to have examined the recent studies and shown the evidence not to be robust to specification changes we argue that the narrow scope of their study does not warrant this claim moreover focusing on our two studies that they have examined we show the deterrence findings to be robust while their work has serious flaws and their reporting appears to be selective the selectivity is biased towards showing no deterrence
