consumption and debt response to unanticipated income shocks evidence from a natural experiment in singapore abstract this paper uses a unique panel dataset of consumer financial transactions to study how consumers respond to an exogenous unanticipated income shock consumption rose significantly after th

the consumption response to predictable changes in discretionary income evidence from the repayment of vehicle loans abstract although the life cycle permanent income hypothesis is the primary framework for understanding household consumption and savings decisions only a few studies have used clearly identifiable income changes to test the basic predictions of the model the estimates produced using this empirical strategy have yet to lead to a consensus of beliefs since the results have both favored and rejected the model this paper contributes to this literature by examining the consumption reaction to predictable increases in discretionary income following the final payment of a vehicle loan using data from the consumer expenditure survey the results show that a 10 increase in discretionary income due to a loan repayment leads to a 2 to 3 increase in nondurable consumption additional analysis suggests that these findings may be explained by the presence of borrowing constraints

testing the response of consumption to income changes with noisy panel data this paper tests the rational expectations lifecycle model of consumption against i a keynesian model and ii the rational expectations lifecycle model with imperfect capital markets the tests are based upon the relative responsiveness of consumption to income changes that can be predicted from past information and income changes that cannot he predicted the tests allow for measurement error in income the results reject the keynesian model and generally support the lifecycle model but the results are not sufficiently precise to rule out the possibility that some households are liquidity constrained measurement error has a strong influence on the relationship between consumption and income

household saving micro theories and micro facts in this survey we review the recent theoretical and empirical literature on household saving and consumption the discussion is structured around a list of motives for saving and how well the standard theory captures these motives we show that almost all of the motives for saving that have been suggested in the informal saving literature can be captured in the standard optimizing model particular attention is given to recent work on the precautionary motive and its implications for saving and consumption behavior we also discuss the behavioral or psychological approach that eschews the use of standard optimization techniques and focuses instead on direct consideration on saving we provide a section on facts who save and how much we then discuss informally the recent decline in the u s saving rate and whether the theory is of much use in understanding this and other changes in aggregate saving rates over time we do not find any convincing explanation for the change in saving rates we also discuss some analyses of saving behavior over the life cycle addressing such questions as whether households save enough for retirement and whether the consumption patterns of older households can be rationalized within a simple life cycle model we also review a great number of studies of the consumption euler equations based on our analysis of the studies cited we conclude that there is still mixed evidence that consumption is excessively sensitive to income we also examine in depth the recent empirical literature on the precautionary motive we conclude that although some households do seem to have a significant precautionary motive at some points in their life cycle this motive is not so strong empirically as some investigators suggest

do banks pass through credit expansions to consumers who want to borrow we examine the ability of policymakers to stimulate household spending during the great recession by reducing banks cost of funds using panel data on 8 5 million credit cards and 743 credit limit regression discontinuities we find that the one year marginal propensity to borrow mpb is declining in credit score falling from 59 for consumers with fico scores below 660 to essentially zero for consumers with fico scores above 740 we use the same credit limit discontinuities combined with a model of lending to estimate banks marginal propensity to lend mpl out of a decrease in their cost of funds for the lowest fico score consumers higher credit limits sharply reduce profits from lending limiting banks incentives to pass through credit expansions to these consumers we conclude that banks mpl is lowest for consumers with the highest mpb and discuss the implications for policies that aim to stimulate the economy through banks

do free goods stick to poor households experimental evidence on insecticide treated bednets summary if the market allocates goods to those willing and able to pay the most for them efforts to target durable health goods such as insecticide treated bednets itns to poor populations may prove ineffective with the poor reselling donated goods to the non poor who value them more highly however low market demand may be due to liquidity constraints rather than low valuation of nets the endowment effect also militates against the resale of in kind transfers we quantify these two effects through a field experiment in uganda our results indicate that very few nets will be resold by recipient households

consumer spending and the economic stimulus payments of 2008 abstract we measure the change in household spending caused by receipt of the economic stimulus payments of 2008 using questions added to the consumer expenditure survey and variation from the ran

the response of expenditures to anticipated income changes panel data estimates standard models of intertemporal allocation predict that the time path of expenditures should be independent of the time path of income recently two papers parker 1999 and souleles 1999 have suggested that u s households have a high marginal propensity to spend within year anticipated income changes we use an expenditure survey panel from spain to re examine this issue we exploit two important features of the spanish data first we have quarterly panel data that follows households for more than four quarters second we use the fact that workers are exogenously sorted into one of two payment schemes some receive the same amount each month of the year and others receive an extra payment in june and december the extra payment is large and predictable we examine the detailed pattern of expenditures over the year to see whether they differ between the two groups we fail to find even weak differences we complement this with a conventional euler equation analysis of excess sensitivity our predicting equation for quarterly earnings growth is much better than usual and is likely to give a powerful test of the hypothesis that predictable changes in income do not lead to changes in expenditure patterns the results of this analysis confirm the graphical analysis we find no evidence of excess sensitivity we conclude that households in normal times do smooth consumption over the year we suggest a reconciliation of our results with those of parker and souleles

luxuries are easier to postpone a proof we show that marshallian income elasticities are proportional to frisch own price elasticities if all goods are additively separable this implies that luxuries are likely to be easier to postpone it also implies that preferences over consumption are unlikely to display a constant elasticity of substitution

unemployment and real interest rates econometric testing of inflation neutrality roeconomics has in its simpler characterizations asserted three hypotheses about the economy first the short run expectationsaugmented phillips curve is vertical second the real rate of interest is independent of anticipated inflation third expectations are formed rationally in the sense that people use mathematical expectations conditional on available information the three propositions together suggest the neutrality of the economy with respect to anticipated inflation in this paper i propose a set of regression based econometric tests of these three neutrality propositions i carry out simple versions of these tests for the postwar american economy such neutrality propositions distinguish the modern neoclassical school from the traditional american keynes hicks school of macroeconomics it is true that these state

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

consumption and income seasonality in thailand many households in developing countries rely on seasonal agriculture for their incomes this paper investigates whether household consumption expenditure tracks income across seasons using data from thailand i contrast the seasonal consumption patterns of households with different seasonal income patterns and estimate the responsiveness of seasonal consumption to seasonal income i find little evidence that consumption tracks income over the course of the year the findings suggest that observed seasonal consumption patterns are the result of seasonal variations in preferences or prices common to all households rather than an inability of households to use savings behavior to smooth consumption

do consumers react to anticipated income changes evidence from the alaska permanent fund a central implication of the life cycle permanentincome hypothesis lc pih is that consumers should not respond to predictable changes in their income to test this hypothesis a number of recent papers have exploited natural experiments to identify anticipated income changes in particular recent work by parker 1999 uses the change in after tax income due to the cap on earnings subject to the social security tax and a related paper by souleles 1999 examines the response of consumption to income tax refunds surprisingly parker and souleles find that even when income is expected to change within the year expenditure is excessively sensitive to the timing of the income change while their results can be interpreted as evidence that our canonical model of consumption is inadequate an alternative explanation is that the anticipated income changes they exploit are small and irregular and that households will not bother to change their consumption paths when the computational costs involved are large relative to the utility gains in support of this interpretation browning and collado 2001 find that the seasonal consumption patterns of spanish households that work in sectors that provide regular bonus payments do not differ from those of households that do not receive bonus payments this paper adds to this evidence by exploiting a natural experiment provided by annual payments from the state of alaska s permanent fund to every resident in the state of alaska that should yield an unusually powerful test of the lc pih these payments are large and clearly anticipated by alaskan residents using the variation in the size of the payments over time and in the amount received by families of different sizes to identify the response of consumption to payments from the permanent fund i find no evidence that the consumption of alaskan households reacts to these payments in addition i find no evidence that the seasonal pattern of consumption in alaska differs from that in the other 49 states or that households in alaska are subject to fewer liquidity constraints engage in less buffer stock saving or spend a smaller fraction of their income on semidurable goods than households in the rest of the united states however although households in alaska do not overreact to payments from the permanent fund i find that the consumption of the very same households is excessively sensitive to their income tax refunds this evidence suggest that households will take anticipated income changes into account in their consumption decisions when the income changes are large regular and easy to predict but will not do so when they are small and irregular the paper proceeds as follows the next section of the paper presents details on the department of economics princeton university princeton nj 08544 and national bureau of economic research e mail chsieh princeton edu i am very grateful to the bureau of labor statistics bls for providing access to the data from the consumer expenditure survey and to its staff particularly steven henderson walter vandeheide and wolf weber for their generous assistance during my visits to the bls i also thank nanci jones for providing data and patiently answering questions on the operation of the alaska permanent fund anne case angus deaton jonathan parker and two referees provided useful comments the views expressed in this paper are personal and should not be attributed to the bls 1 i refer to the certainty equivalent version of the lc pih or one in which the expected variance of consumption is constant as is well known without these assumptions the lc pih only implies smoothing of marginal utility not necessarily of consumption 2 see christina h paxson 1992 john shea 1995 jonathan a parker 1999 nicholas s souleles 1999 martin browning and m dolores collado 2001 also see ronald a bodkin 1959 for an early example of the use of a natural experiment to test for excess sensitivity for comprehensive reviews of the large literature on empirical tests of the lc pih see angus deaton 1992 browning and annamaria lusardi 1996 and browning and thomas f crossley 2001 3 in 1998 for example the permanent fund paid 1 541 to every resident of the state of alaska

does the benefits schedule of cash assistance programs affect the purchase of temptation goods evidence from peru a critique of cash assistance programs is that beneficiaries may spend the money on temptation goods such as alcohol and tobacco we exploit a change in the payment schedule of peru s conditional cash transfer program to identify the impact of benefit receipt frequency on the purchase of temptation goods we use annual household data among cross sectional and panel samples to analyze the effect of the policy change on the share of the household budget devoted to four categories of temptation goods using a difference in differences estimation approach we find that larger less frequent payments increased the expenditure share of alcohol by 55 80 and sweets by 10 40 although the absolute magnitudes of these effects are small our study suggests that less frequent benefits scheduling may lead cash recipients to make certain types of temptation purchases

extending quadrature methods to value multi asset and complex path dependent options abstract the exposition of the quadrature quad method andricopoulos widdicks duck and newton 2003 universal option valuation using quadrature methods journal of financial economics 67 447 471 see also corrigendum journal of financial economics 73 603 2004 is significantly extended to cover notably more complex and difficult problems in option valuations involving one or more underlyings trials comparing several techniques in the literature adapted from standard lattice grid and monte carlo methods to tackle particular types of problem show that quad offers far greater flexibility superior convergence and hence increased accuracy and considerably reduced computational times the speed advantage of quad means that even under the curse of dimensionality it is not necessary to resort to monte carlo methods certainly for options involving up to five underlying assets given the universality and flexibility of the method it should be the method of choice for pricing options involving multiple underlying assets in the presence of many features such as early exercise or path dependency

intertemporal consumption durables and liquidity constraints a cohort analysis we provide a theoretical framework to analyse the response of life time maximizing consumers to intertemporal prices of non durable goods and durable goods when the borrowing limit depends on the market value of the stock of durables owned by the consumer we use pseudo panel data on purchases of non durables and durable goods cars and demographic characteristics from the uk family expenditure survey as well as estimates of the durable stock constructed using the uk national travel survey to estimate the equations derived in the first part of the paper we evaluate the shadow prices of these restrictions which were significantly positive for younger consumers in the mid seventies and immediately prior to the 1982 financial liberalisation

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

correlation consumption confusion or constraints why do poor children perform so poorly the economic and social mobility of a generation may be largely determined by the time it enters school given early developing and persistent gaps in child achievement by family income and the importance of adolescent skill levels for educational attainment and lifetime earnings after providing new evidence of important differences in early child investments by family income we study four leading mechanisms thought to explain these gaps an intergenerational correlation in ability a consumption value of investment information frictions and credit constraints in order to better determine which of these mechanisms inf uence family investments in children we evaluate the extent to which these mechanisms also explain other important stylized facts related to the marginal returns on investments and the effects of parental income on child investments and skills

wealth shocks unemployment shocks and consumption in the wake of the great recession we use data from the 2009 internet survey of the health and retirement study to examine the consumption impact of wealth shocks and unemployment during the great recession in the us we find that many households experienced large capital losses in housing and in their financial portfolios and that a non trivial fraction of respondents have lost their job as a consequence of these shocks many households reduced substantially their expenditures we estimate that the marginal propensities to consume with respect to housing and financial wealth are 1 and 3 3 percentage points respectively in addition those who became unemployed reduced spending by 10 percent we also distinguish the effect of perceived transitory and permanent wealth shocks splitting the sample between households who think that the stock market is likely to recover in a year s time and those who don t in line with the predictions of standard models of intertemporal choice we find that the latter group adjusted much more than the former its spending in response to financial wealth shocks

do liquidity constraints and interest rates matter for consumer behavior evidence from credit card data this paper utilizes a unique new dataset of credit card accounts to analyze how people respond to changes in credit supply the data consist of a panel of thousands of individual credit card accounts from several different card issuers with associated credit bureau data we estimate both marginal propensities to consume mpcs out of liquidity and interest rate elasticities we also evaluate the ability of different models of consumption to rationalize our results distinguishing the permanent income hypothesis pih liquidity constraints precautionary saving and behavioral models we find that increases in credit limits generate an immediate and significant rise in debt counter to the pih the average mpc out of liquidity ddebt dlimit ranges between 10 14 the mpc is much larger for people starting near their limits consistent with binding liquidity constraints however the mpc is significant even for people starting well below their limit we show this response is consistent with buffer stock models of precautionary saving nonetheless there are other results that conventional models cannot easily explain e g why so many people are borrowing on their credit cards and simultaneously holding low yielding assets unlike most other studies we also find strong effects from changes in account specific interest rates the long run elasticity of debt to the interest rate is approximately 1 3 less than half of this elasticity represents balance shifting across cards with most reflecting net changes in total borrowing the elasticity is larger for decreases in interest rates than for increases which can explain the widespread use of temporary promotional rates the elasticity is smaller for people starting near their credit limits again consistent with liquidity constraints

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

the fisher effect in a signal extraction framework the recent brazilian experience abstract this paper derives a signal extraction framework for examining all testable implications of the fisher equation the signal is the net of taxes nominal interest rate which under the fisher model equals inflation expectation plus the real rate assumed to be constant or a constant plus a martingale difference all alternative linear models can be represented as noise added to the signal the international and brazilian literature are briefly reviewed and the empirical tests reinterpreted in the signal extraction framework the model is tested with brazilian data for the period 1973 1990 using interest rate data on non indexed certificates of deposit from a sample of major brazilian banks the framework detects little noise i e the fisher equation seems to reasonably fit the brazilian evidence this result carries the policy implication that the government cannot have the burden of financing its fiscal deficits ameliorated by issuing non indexed debt in periods when inflation is escalating given the large fluctuations observed in ex post real rates in brazil the reasonable success of the fisher equation also implies the existence of large inflation forecast errors which suggest the need for further research on how agents form inflation expectations when inflation escalates rapidly as it did in the late 1980s in brazil price indices lag behind true inflation this generates a fisher effect even for indexed securities the empirical evidence also corroborates the existence of this fisher effect for indexed securities

the life cycle model of consumption and saving a central implication of life cycle models is that agents smooth consumption we review the empirical evidence on smoothing at frequencies from within the year up to across a lifetime we find that life cycle models particular those which incorporate realistic features of markets and goods have more empirical successes than failures we also show that some apparent deviations from theoretical predictions imply very small welfare losses for agents finally we emphasize that the coherence of life cycle models imposes an important discipline when incorporating new features into models

the spending and debt response to minimum wage hikes abstract immediately following a minimum wage hike household income rises on average by about 250 per quarter and spending by roughly 700 per quarter for households with minimum wage workers most of the spending response is caused by a small number of households who purchase vehicles furthermore we find that the high spending levels are financed through increases in collateralized debt our results are consistent with a model where households can borrow against durables and face costs of adjusting their durables stock jel d12 d14 d91 j38

the timing of pay abstract there exists large and persistent variation in not only how but when employees are paid a fact unexplained by existing theory this paper develops a simple model of optimal pay timing for firms when workers have self control problems they under save and experience volatile consumption between paychecks thus pay whose delivery matches the timing of workers consumption needs will reduce wage costs the model also explains why pay timing should be regulated as it is in practice although the worker benefits from a timing profile that smoothes her consumption her lack of self control induces her to attempt to undo the arrangement either by renegotiating with her employer or by taking out payday loans regulation of pay timing and consumer borrowing is required to counter these efforts helping the worker help herself

consumption down payments and liquidity constraints one frequently cited explanation for the empirical failure of the orthodox life cycle permanent income hypothesis lc pih is the presence of binding liquidity constraints households inability to borrow and lend at the same interest rate or to borrow the desired quantity can distort household consumption profiles depressing consumption during periods when constraints bind whether or not liquidity constraints bind has important implications for the sensitivity of consumption to fluctuations in income the neutrality of government debt and the structure of taxation despite the potential importance of liquidity constraints in understanding macroeconomic behavior there has been comparatively little research into the effect of specific constraints on consumption one area of consumer behavior where liquidity constraints arguably may be important is in housing decisions and mortgage markets households wishing to own a first home must accumulate a down payment in order to qualify for a mortgage loan currently for conventional mortgages in the united states most lending institutions require between s percent and 20 percent of the purchase price of the home put down in advance of the purchase 2 without access to private gifts or loans many

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

measuring corruption in china an expenditure based approach using household survey data most existing micro level empirical analyses of corruption rely on administrative records special purpose surveys or field experiments which can be difficult or very costly to obtain in some situations in this paper we apply an expenditure based method of quantifying the extent of corruption in a particular country using household survey data this method utilizes discrepancies between consumption and reported income to measure corruption another contribution of this paper is that it provides the first objective estimate of the extent of corruption in china we use a quadratic clothing expenditure function to estimate the extent of corruption in china in 2002

does consumption respond to predicted increases in cash hand availability evidence from the italian severance pay abstract we examine whether italian household consumption exhibits excess sensitivity to severance pay a sizable lump sum that workers receive at job termination we find no evidence of excess sensitivity of non durable expenditure to this anticipated cash in hand change

early and late human capital investments borrowing constraints and the family we develop a dynastic human capital investment framework to study the importance of family borrowing constraints and uninsured labor market risk as well as the process of intergenerational ability

liquidity constraints and intertemporal consumer optimization theory and evidence from durable goods this paper develops and tests the implications of optimal consumption behavior with borrowing constraints the theory shows that liquidity constraints imply a distinctive intertemporal relationship between durable and nondurable goods consumption binding liquidity constraints appear as part of an error correction term derived from the long run cointegrating relationship between durables and nondurables when liquidity constraints are binding the error correction term will have predictive power for the future change in nondurable consumption empirical tests of the implications using aggregate data support the hypothesis that liquidity constraints rather than rule of thumb behavior best explain the excess sensitivity of consumption to predictable changes in income copyright 1995 by ohio state university press

college tuition and household savings and consumption abstract despite the high cost of college there has been little study of the adequacy of household savings and other resources available to fund college to gauge their adequacy this paper examines households standard of living as they pay for college using the consumer expenditure survey the main finding is that households appear to do a relatively good job smoothing their consumption into the academic year despite large expenses this is consistent with the life cycle theory of saving and consumption there is some evidence of a delayed decline in consumption and of a decline for households with children first beginning college but the magnitudes of these declines are rather small

the permanent income hypothesis and the real interest rate some evidence from panel data abstract a test of the permanent income hypothesis in panel data is formulated taking into account both the time series and cross section variation in the rate of return the over identifying restrictions of the theory rejected

adjustment of consumers durables stocks evidence from automobile purchases this paper tests an optimal s s rule in household durable purchases and examines directly the resulting aggregate expenditure dynamics the observed decision rule responds to income uncertainty and growth as predicted by an s s model resulting from transactions costs tests against liquidity constraints find that about half the households purchase according to an optimal s s rule aggregating the s s rule over households produces a cross section distribution of durables holdings the empirical distribution is similar to that predicted theoretically as is its response to aggregate shocks furthermore simulations of aggregate expenditure based on the household distribution exhibit dynamics consistent with those observed in the 1980s

short term interest rates as predictors of inflation on testing the hypothesis that the real rate of interest is constant in an innovative and provocative paper in this review eugene fama presents evidence which appears to be consistent with the joint hypothesis that the real rate of interest ignoring taxes is a constant and that the market for u s treasury bills is efficient in the sense of embodying rational expectations those findings are strikingly at variance with a long list of previous studies which seemed to support the view that the real rate of interest varies over time and can be related to economic variables such as real output monetary policy and so forth 2 the methodologies which lead to these contradictory conclusions are quite different previous studies had followed the lead of irving fisher by relating nominal interest rates to distributed lags on past rates of inflation 3 these distributed lags are generally interpreted as approximations to the market s expected rate of inflation and thus any remaining variation is attributed to variation in the real rate 4 fama s methodology on the other hand draws on the fact that the difference between the market interest rate and the subsequently observed rate of inflation the ex post real interest rate consists by definition of the ex ante real interest rate plus a pure forecasting error 5 the hypothesis of market efficiency implies that these forecasting errors must be serially random thus observing ex post real rates is equivalent to observing ex ante real rates with random measurement error these errors of course confound the problem of identifying variation in the ex ante real rate in this paper we will argue that the relative magnitude of these measurement errors is such that the tests carried out by fama were not powerful enough to reject the joint hypothesis that the ex ante real rate is a constant and expectations are rational more powerful tests which are presented in this paper using the same data do lead to rejection of that hypothesis of course rejection
