booms busts and babies health we study the relationship between the unemployment rate at the time of a baby s conception and parental characteristics parental behaviors and babies health babies conceived in times of high unemployment have a reduced incidence of low and very low birth weight fewer congenital malformations and lower post neonatal mortality these health improvements are attributable both to selection changes in the type of mothers that conceive during recessions and to improvements in health behavior during recessions black mothers tend to be higher socio economic status as measured by education and marital status in times of high unemployment whereas white mothers are less educated

price setting during low and high inflation evidence from mexico this paper provides new insight into the relationship between inflation and the setting of individual prices by examining a large data set of mexican consumer prices covering episodes of both low and high inflation when the annual rate of inflation is low below 10 15 the frequency of price changes comoves weakly with inflation because movements in the frequency of price decreases and increases partly offset each other in contrast the average magnitude of price changes correlates strongly with inflation because it is sensitive to movements in the relative shares of price increases and decreases when inflation rises beyond 10 15 few price decreases are observed and both the frequency and average magnitude are important determinants of inflation i show that a menu cost model with idiosyncratic technology shocks predicts the average frequency and magnitude of price changes well over a range of inflation similar to that experienced by mexico

investigating the cost performance of uk credit unions using radial and non radial efficiency measures abstract this paper examines the relative efficiency of uk credit unions radial and non radial measures of input cost efficiency plus associated scale efficiency measures are computed for a selection of input output specifications both measures highlighted that uk credit unions have considerable scope for efficiency gains it was mooted that the documented high levels of inefficiency may be indicative of the fact that credit unions based on clearly defined and non overlapping common bonds are not in competition with each other for market share credit unions were also highlighted as suffering from a considerable degree of scale inefficiency with the majority of scale inefficient credit unions subject to decreasing returns to scale the latter aspect highlights that the uk government s goal of larger credit unions must be accompanied by greater regulatory freedom if inefficiency is to be avoided one of the advantages of computing non radial measures is that an insight into potential over or under expenditure on specific inputs can be obtained through a comparison of the non radial measure of efficiency with the associated radial measure two interesting findings emerged the first that uk credit unions over spend on dividend payments and the second that they under spend on labour costs

optimal monetary policy responses to relative price changes abstract an optimizing model with a flexible price sector and a sticky price sector is presented to analyze the effects of relative price changes on inflation fluctuations the relative price of the flexible price good represents a shift parameter of the new keynesian phillips curve the optimal monetary policy is to target sticky price inflation rather than a broad inflation measure although stabilizing the relative price around its efficient value is one of the appropriate goals of the central bank stabilizing sticky price inflation is sufficient for achieving this goal an optimal monetary policy for a small open economy is also discussed

lasting or latent scars swedish evidence on the long term effects of job displacement recently improved swedish register data have made it possible to remedy many weaknesses of previous research on displaced workers using linked employer employee data we identify all workers displaced in 1987 due to an establishment closure and follow them over both a predisplacement period of 4 years and a postdisplacement period stretching until 1999 we find that the displaced workers suffer both earnings losses and worsened labor market position not only during a transitory period of adjustment but also in the longer run these longer run effects seem to be driven by an increased sensitivity to subsequent macroeconomic shocks

what measure of inflation should a developing country central bank target in closed or open economy models with complete markets targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium we analyze this result in the context of developing economies where a large proportion of households are credit constrained and the share of food expenditures in total consumption expenditures is high we develop an open economy model with incomplete financial markets to show that headline inflation targeting improves welfare outcomes we also compute the optimal price index which includes a positive weight on food prices but unlike headline inflation assigns zero weight to import prices

the short term mortality consequences of income receipt many studies find that households increase their co nsumption after the receipt of expected income payments a result inconsistent wit h the life cycle permanent income hypothesis consumption can increase adverse healt h events such as traffic accidents heart attacks and strokes in this pape r we examine the short term mortality consequences of income receipt we find that mortality increases following the arrival of monthly social security payments re gular wage payments for military personnel the 2001 tax rebates and alaska permane nt fund dividend payments the increase in short run mortality is large potential ly eliminating some of the protective benefits of additional income

consumer response to the timing of income evidence from a change in tax withholding in 1992 the income tax withholding tables were adjusted so that withholding was reduced a typical worker received an extra 28 80 in take home pay per month in march through december 1992 to be offset by a lower tax refund in 1993 the change in withholding amounted to 0 5 percent of gdp president bush who proposed this change in his state of the union address intended that it provide a temporary stimulus to demand but the policy change involved only the timing of income so under the life cycle permanent income model it would be predicted to have a negligible effect on consumption and aggregate demand this paper reports consumers responses to the change in withholding the results are based on a survey taken shortly after it went into effect forty three percent of consumers report spending the extra take home pay substantially more than the zero percent predicted by the standard models but substantially less than the one hundred percent upon which the policy was predicated the decision to save the income is not explained by expected income growth therefore while behavior of many households is not fully consistent with the life cycle permanent income model liquidity constraints do not appear to account for this behavior this abstract was borrowed from another version of this item

optimal monetary policy in a currency area abstract this paper investigates how monetary policy should be conducted in a two region general equilibrium model with monopolistic competition and price stickiness this framework delivers a simple welfare criterion based on the utility of the consumers that can be used to evaluate monetary policy in a currency area if the two regions share the same degree of nominal rigidity the terms of trade are completely insulated from monetary policy and the optimal outcome is obtained by targeting a weighted average of the regional inflation rates these weights coincide with the economic sizes of the region if the degrees of rigidity are different the optimal plan implies a high degree of inertia in the inflation rate but an inflation targeting policy in which higher weight is given to the inflation in the region with higher degree of nominal rigidity is nearly optimal

household expenditure and the income tax rebates of 2001 using questions expressly added to the consumer expenditure survey we estimate the change in consumption expenditures caused by the 2001 federal income tax rebates and test the permanent income hypothesis we exploit the unique randomized timing of rebate receipt across households households spent 20 to 40 percent of their rebates on nondurable goods during the three month period in which their rebates arrived and roughly two thirds of their rebates cumulatively during this period and the subsequent three month period the implied effects on aggregate consumption demand are substantial consistent with liquidity constraints responses are larger for households with low liquid wealth or low income

monetary policy and food inflation in south africa a quantile regression analysis abstract although optimal monetary policy stabilizes food inflation theoretically empirical studies remain limited not only in the context of volumes and the estimation approaches but are focused on selected advanced and emerging countries to the neglect of africa where poverty and dominance of food in the consumption basket are more pronounced we provide empirical evidence in the context of south africa using quantile regressions rising food prices are destabilized even further by restrictive monetary policy a finding that has ramifications for inflation targeting especially given that a quarter of the country s population is food poor

modelling the impact of central bank intervention on exchange rate volatility under inflation targeting this article empirically investigates the effect of central bank s foreign exchange interventions on the level and volatility of the uganda shilling us dollar exchange rate ugx usd under an infla

the reaction of household consumption to predictable changes in social security taxes the key implication of rational expectations and the basic life cycle permanent income hypothesis that predictable changes in income have no effect on the growth rate of consumption expenditures is examined this implication is important for understanding the effectiveness and optimal timing of fiscal policy the causes and propagation of business cycles and the effects of income fluctuations on the growth rate of the economy using household level consumption data from the consumer expenditure survey whether expenditures on nondurable goods increase contemporaneously with predictable changes in social security tax withholding is tested it is found that households do change their consumption expenditures in response to the predictable fluctuations in income induced by the social security tax system

union contracts and the life cycle permanent income hypothesis this paper isolates households in the psid whose heads can be matched to particular long term union contracts with high confidence the author uses use published information on these contracts to construct a household specific measure of expected wage growth he finds that predictable wage movements are significantly correlated with consumption changes contrary to neoclassical consumption theory the author finds that consumption responds more strongly to predictable income declines than to predictable income increases this asymmetry is inconsistent with liquidity constraints and myopia but is qualitatively consistent with models in which preferences exhibit loss aversion copyright 1995 by american economic association

world food prices and monetary policy abstract how should monetary policy respond to large fluctuations in world food prices we study this question in an open economy model in which imported food has a larger weight in domestic consumption than abroad and international risk sharing can be imperfect a key novelty is that the real exchange rate and the terms of trade can move in opposite directions in response to world food price shocks this exacerbates the policy trade off between stabilizing output prices vis a vis the real exchange rate to an extent that depends on risk sharing and the price elasticity of exports we characterize implications for dynamics optimal monetary policy and the relative performance of practical monetary rules while cpi targeting and expected cpi targeting can dominate ppi targeting if international risk sharing is perfect even seemingly mild departures from the latter make ppi targeting a winner

optimal simple and implementable monetary and fiscal rules welfare maximizing monetary and fiscal policy rules are studied in a model with sticky prices money and distortionary taxation the ramsey optimal policy is used as a point of comparison the main findings are the size of the inflation coefficient in the interest rate rule plays a minor role for welfare it matters only insofar as it affects the determinacy of equilibrium optimal monetary policy features a muted response to output interest rate rules that feature a positive response to output can lead to significant welfare losses the welfare gains from interest rate smoothing are negligible optimal fiscal policy is passive the optimal monetary and fiscal rule combination attains virtually the same level of welfare as the ramsey optimal policy

health insurance and mortality experimental evidence from taxpayer outreach we evaluate a randomized pilot study in which the irs sent informational letters to 3 9 million taxpayers who paid a tax penalty for lacking health insurance coverage under the affordable care act drawing on administrative data we study the effect of the intervention on taxpayers subsequent health insurance enrollment and mortality we find the intervention led to increased coverage in the two years following treatment and that this additional coverage reduced mortality among middle aged adults over the same time period our results provide the first experimental evidence that health insurance reduces mortality

local exchange trading systems as a response to the globalisation of capitalism the globalisation of capitalism has disadvantaged those people and places marginal to the capitalist development process the local exchange trading system represents a possible approach to the challenge of relocalising social and economic identity despite the growing importance of local exchange trading systems lets in the uk geographical research into the concept is limited this paper examines the potential of lets as a response to the hegemonic influence of global capitalism the empirical evidence focuses on the development and operation of lets in glasgow the research analyses both successful and unsuccessful lets in the city examines the prospects for further development of lets in the uk and considers the potential value of the concept particularly for people and places disadvantaged by the capitalist market economy

income receipt and mortality evidence from swedish public sector employees in this paper we study the short run effect of salary receipt on mortality among swedish public sector employees by exploiting variation in paydays across work places we completely control for mortality patterns related to for example public holidays and other special days or events coinciding with paydays and for general within month and within week mortality patterns we find a dramatic increase in mortality on the day that salaries arrive the increase is especially pronounced for younger workers and for deaths due to activity related causes such as heart conditions and strokes the effect is entirely driven by an increase in mortality among low income individuals who are more likely to experience liquidity constraints all things considered our results suggest that an increase in general economic activity on salary receipt is an important cause of the excess mortality

liquidity economic activity and mortality abstract we document a within month mortality cycle where deaths decline before the first day of the month and spike after the first this cycle is present across a wide variety of causes and demographic groups a similar cycle exists for a range of economic activities suggesting the mortality cycle may be due to short term variation in levels of economic activity we provide evidence that the within month activity cycle is generated by liquidity our results suggest a causal pathway whereby liquidity problems reduce activity which in turn reduces mortality these relationships may help explain the procyclical nature of mortality

why are recessions good for your health a series of influential papers by christopher j ruhm 2000 2003 2005 2008 documents that recessions are good for your health or more specifically that state level mortality rates are strongly procyclical the magnitude of the correlation is economically meaningful a typical estimate from the literature suggests that a 1 percentage point increase in a state s unemployment rate is associated with a 0 54 percent reduction in that state s mortality rates if this reflects a causal relationship that is also valid at the national level then a 1 percentage point increase in the unemployment rate would translate based on 2004 mortality rates into about 12 000 fewer deaths per year these findings are frequently interpreted as resulting from the rising opportunity cost of time that accompanies better labor market opportunities and some empirical support exists for this interpretation for example ruhm 2000 shows that obesity and smoking also exhibit a procyclical pattern the economy and health

exchange rates and monetary policy in emerging market economies this paper investigates the effects of exchange rate regimes and alternative monetary policy rules for an emerging market economy that is subject to a volatile external environment in the form of shocks to world interest rates and the terms of trade in particular we highlight the impact of financial frictions and the degree of exchange rate pass through in determining the relative performance of alternative regimes in stabilizing the economy in the face of external shocks our results are quite sharp when exchange rate pass through is high a policy of non traded goods inflation targeting does best in stabilizing the economy and is better in welfare terms when exchange rate pass through is low however a policy of strict cpi inflation targeting is better in all cases a fixed exchange rate is undesirable in addition financial frictions have no implications for the ranking of alternative policy rules

does job loss shorten life this paper examines the impact of job loss on overall and cause specific mortality using linked employer employee data we identified the workers displaced due to all establishment closures in sweden in 1987 and 1988 hence we have extended the case study approach which has dominated the plant closure literature the overall mortality risk among men increased by 44 percent during the first four years following job loss while there was no impact on either female overall mortality or in the longer run for both sexes however there was an about twofold short run increase in suicides and alcohol related mortality

is there a daily discount rate evidence from the food stamp nutrition cycle abstract quasi hyperbolic discounting predicts impatience over short run tradeoffs i present a direct non laboratory test of this implication using data on the nutritional intake of food stamp recipients caloric intake declines by 10 to 15 percent over the food stamp month implying a significant preference for immediate consumption these findings constitute a rejection of the permanent income hypothesis and are extremely difficult to reconcile with exponential discounting the data support an explanation based on time preference and reject several alternative explanations including highly elastic intertemporal substitution i explore implications for the optimal timing of transfer payments under alternative assumptions about preferences

the effects of government transfers on monthly cycles in drug abuse hospitalization and mortality this paper analyzes the monthly patterns of adverse outcomes due to the consumption of illegal drugs by recipients of government transfer payments we find evidence that certain subpopulations on government cash aid significantly increase their consumption of drugs when their checks arrive at the beginning of the month and as a result experience adverse events including hospitalization and death using data from california we find that the overall rate of drug related hospital admissions increases abruptly at the beginning of the month with admissions increasing 23 during the first five days of the month we find that this cycle is driven largely by recipients of supplemental security income ssi ssi recipients also experience an abrupt 22 increase in within hospital mortality after receiving their checks these findings suggest that full wallets adversely affect some aid recipients and that policymakers should explore alternate disbursement regimes such as a staggered disbursement schedule or in kind support that have the potential to reduce the rate of adverse events

paycheque receipt and the timing of consumption this article examines the consumption response to monthly paycheque receipt since the amount and arrival date of paycheques are known in advance the receipt of a paycheque does not coincide with the receipt of new information under the basic rational expectations life cycle permanent income hypothesis household consumption should not respond to paycheque arrival using data from the uk s family expenditure survey this article finds that household consumption is excessively sensitive to paycheque receipt the results cannot be explained by any underlying monthly expenditure fluctuations common to all households the presence of liquidity constraints as measured by wealth and age can account for the excess sensitivity results

wealth health and child development evidence from administrative data on swedish lottery players we use administrative data on swedish lottery players to estimate the causal impact of substantial wealth shocks on players own health and their children s health and developmental outcomes our estimation sample is large virtually free of attrition and allows us to control for the factors conditional on which the prizes were randomly assigned in adults we find no evidence that wealth impacts mortality or health care utilization with the possible exception of a small reduction in the consumption of mental health drugs our estimates allow us to rule out effects on 10 year mortality one sixth as large as the crosssectional wealth mortality gradient in our intergenerational analyses we find that wealth increases children s health care utilization in the years following the lottery and may also reduce obesity risk the effects on most other child outcomes including drug consumption scholastic performance and skills can usually be bounded to a tight interval around zero overall our findings suggest that in affluent countries with extensive social safety nets causal effects of wealth are not a major source of the wealth mortality gradients nor of the observed relationships between child developmental outcomes and household income jel codes i10 i14 j24

the terms of trade the real exchange rate and economic fluctuations this paper examines the relationship between terms of trade and business cycles using a three sector intertemporal equilibrium model and a large multicountry database results show that terms of trade shocks account for nearly one half of actual gdp variability the model explains weak correlations between net exports and terms of trade the harberger laursen and metzler effect and produces large and weakly correlated deviations from purchasing power parity and real interest rate parity terms of trade shocks cause real appreciations and positive interest differentials although productivity shocks have opposite effects the puzzle that welfare gains of international asset trading are negligible is left unresolved copyright 1995 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

healthy bodies and thick wallets the dual relation between health and economic status there is abundant evidence of a quantitatively large association between many measures of economic status including income and wealth and a variety of health outcomes such as mortality or morbidity however considerable and often heated debate remains especially across disciplines about the direction of causation and about why the association arises although medical scientists are often convinced that the dominant if not exclusive pathway is that variation in socioeconomic status produces health disparities they are increasingly debating among themselves about why low economic status might lead to poor health at least for modern industrial countries 1 the old standby arguments the less well to do have access to less or lower quality medical care or a stronger pattern of deleterious personal behaviors have been rejected as insufficient instead a series of intriguing competing theories have arisen that emphasize long term impacts of early childhood or even inter uterine environmental factors the cumulative effects of prolonged exposures to individual stressful events or reactions to macro societal factors such as rising levels of income inequality a common link is that each theory attempts to document the physiological processes through which low economic status leads to poorer health while these scientific questions are extremely important this research has taken place with little input from economists economists are now making contributions about the alternative pathway the impact poor health may have on economic resources poor health may restrict a family s capacity to earn income or to accumulate assets by limiting work or by raising medical expenses at a minimum this work should provide a caution against exaggerating the magnitude of causation from economic status to health outcomes but the potential contribution runs deeper as people age the evolving variation in individual health outcomes may offer additional statistical information to estimate parameters of household savings and consumption behavior that so far have proven to be somewhat elusive thus incorporating health uncertainty and risk into economic models should eventually enrich our understanding of basic tenets of household behavior the first section of this paper documents the size of the association between health and one prominent economic status measure household wealth section two deals with how health influences economic status by sketching out reasons why health may alter household savings and eventually wealth and then providing estimates of the empirical magnitude of these effects section three shifts attention to the alternative pathway the links between economic status and health and summarizes 2major controversies and evidence surrounding these issues

the response of household consumption to income tax refunds a central implication of the life cycle or permanent income theory is that consumption should not respond to predictable fluctuations in income tests of this implication have yielded mixed results especially on micro data angus deaton 1992 martin browning and annamaria lusardi 1996 in large part this might be due to the difficulties of isolating the predictable component of income at the micro level most tests proceed by instrumenting for income but since the available instruments are typically poor such tests might be prejudiced against finding significant excess sensitivity of consumption to income john shea 1995 also it is not clear how closely the resulting econometric predictions of income coincide with agents actual expectations of income to avoid these difficulties this paper examines the response of household consumption to a particular type of income that is both predictable and transitory income tax refunds since a refund depends on events in the previous calendar year it is predictable income as regards consumption in the year of its receipt consequently under the life cycle theory consumption should not increase on receipt of a refund 2 in addition to testing the canonical model of consumption this paper provides estimates interpretable as the marginal propensity to consume mpc out of refunds since federal tax refunds now amount to over 80 billion per year averaging well over 1 000 per refund these estimates are of interest in themselves more generally they bear on the impact of even preannounced and temporary changes in fiscal policy the paper begins by surveying related studies in section i section ii describes the data the consumer expenditure survey cex which of the leading u s micro data sets has the most comprehensive coverage of expenditure the empirical specification is set out in section hi section iv reports the results and section v concludes

credit unions and low income communities since the late 1980s the number of community based credit unions in britain has grown steadily these are financial co operatives based on low income neighbourhoods owned and controlled by local residents which aim to provide savings and low cost credit facilities to their members although located in economically disadvantaged communities credit unions are not exclusively used by the poor while better off groups save and borrow more a greater proportion of low income users would not have purchased goods and services in the absence of a credit union credit unions are making useful but marginal contributions to the credit and debt problems of low income families they could probably achieve more with additional resources but any intervention by external agencies should be sensitive and avoid damaging the strong mutual aid foundations upon which credit unions are based

on the welfare cost of economic fluctuations in developing countries macroeconomic fluctuations are much stronger in developing countries than in the united states yet while a large literature debates the welfare cost of economic fluctuations in the united states it remains an open question how large that cost is in developing countries using several models we provide such a measure we find that the welfare cost of consumption volatility per se is far from trivial and averages a substantial multiple of the corresponding u s estimate moreover in many poor countries the welfare gain from eliminating volatility may in fact exceed the welfare gain from an additional percentage point of growth forever

what measure of inflation should a central bank target this paper assumes that a central bank commits itself to maintaining an inflation target and then asks what measure of the inflation rate the central bank should use if it wants to maximize economic stability the paper first formalizes this problem and examines its microeconomic foundations it then shows how the weight of a sector in the stability price index depends on the sector s characteristics including size cyclical sensitivity sluggishness of price adjustment and magnitude of sectoral shocks when a numerical illustration of the problem is calibrated to u s data one tentative conclusion is that a central bank that wants to achieve maximum stability of economic activity should use a price index that gives

3rd of tha month do social security recipients smooth consumption between checks this paper examines the response of consumption expenditures to the monthly receipt of social security checks since the amount and arrival date of these checks are known to the recipients the basic life cycle permanent income hypothesis lcpih predicts that consumption should not respond to the receipt of these checks using daily diary data from the consumer expenditure survey this paper finds evidence that both the dollar amount and probability of expenditures increase immediately following the receipt of this check most relevant to testing the lcpih categories of instantaneous consumption expenditure such as food away from home increase on the check arrival date the response is found primarily amongst households for whom social security is the primary source of income however the magnitude of the estimated responses are relatively small and do not suggest that the utility losses are large from this non smoothing behavior this abstract was borrowed from another version of this item

does financial globalization promote risk sharing article i nfo in theory one of the main benefits of financial globalization is that it should allow for more efficient international risk sharing in this paper we provide an empirical evaluation of the patterns of risk sharing among different groups of countries and examine how international financial integration has affected the evolution of these patterns using a variety of empirical techniques we conclude that there is at best a modest degree of international risk sharing and certainly nowhere near the levels predicted by theory in addition only industrial countries have attained better risk sharing outcomes during the recent period of globalization developing countries have by and large been shut out of this benefit even emerging market economies many of which have reduced capital controls and all of which have witnessed large increases in cross border capital flows have seen little change in their ability to share risk we find that the composition of flows may help explain why emerging markets have not been able to realize this presumed benefi to f financial globalization in particular our results suggest that portfolio debt which had dominated the external liability stocks of most emerging markets until recently is not conducive to risk sharing
