the impact of government size on economic growth a threshold analysis we examine the nature of the relationship between government size and economic growth and identify the optimal level of government size using a large dataset through a novel and very general non linear panel generalized method of moments approach we show that this relationship is statistically significant above and below the optimal level even after splitting our sample to developed and developing countries finally we find an asymmetric impact of government size on economic growth in both developed and developing countries around the estimated threshold

financial wealth consumption smoothing and income shocks arising from job loss one of the reasons for setting up an unemployment insurance scheme is to allow job losers to smooth consumption we test for the impact of unemployment benefits on changes in household food expenditure of individuals who have recently experienced a job loss we also study the relationship between unemployment benefits and the financial wealth of the unemployed from our empirical analysis we conclude that for households without financial wealth at the time of job loss unemployment benefits help to smooth food consumption for households running debt before job loss there is evidence that lower replacement rates lead to a postponement of debt repayment

carbon pass through in the electricity sector an econometric analysis abstract we conduct an econometric analysis to investigate the carbon pass through in the greek electricity sector for this reason we utilize a rich micro level panel dataset including hourly data for 24 thermal power plants spanning the period from january 2014 to december 2017 in order to study the pass through of emissions costs to wholesale electricity prices we employ an instrumental variable approach our findings survived several robustness checks accounting for logged linear and non linear econometric specifications the empirical results indicate the existence of an almost complete pass through revealing that retailers fully internalize the cost of co2 permits this study incurs important policy implications since the complete pass through signify that wholesale electricity prices will increase at least in the short run however the overall effect on retail prices will be mostly affected by the amount of co2 permits and the fuel energy mix

game shows and economic behavior risk taking on card sharks this paper studies individual risk taking behavior with a unique data set risky decisions of contestants during the threeyear history of the television game show card sharks in the bonus round of the game individuals choose how much to wager on positive expected value gambles with known and varying probabilities and large possible payouts since no special skills or knowledge are involved empirical analysis is not complicated by a contestant s superior information about her own abilities stakes can reach 16 000 and average 3 200 few experimental budgets permit even one observation of this magnitude first i simply estimate how risk averse contestants behave under the assumption of expected utility maximization i estimate a lower bound for the coefficient of absolute risk aversion of 0 00031 which when multiplied by per capita u s personal income gives an estimate of relative risk aversion of 4 8 this estimate is higher than most econometric estimates of risk aversion contestants however do not act in a manner consistent with expected utility maximization so this number should not be given a structural interpretation rather it is simply a useful way to summarize average willingness to bear risk of individuals on the show second i explore how individual behavior is inconsistent with expected utility theory the amount a contestant wishes to wager depends critically on the amount of wealth she has accumulated in the bonus round and therefore on the size of the stakes this is at odds with expected utility theory since the size of the stakes although far from insignificant is small relative to a person s wealth contestants should then have close to constant absolute risk aversion with respect to accumulated winnings in the game a more striking result deals with contestants who had previ

why do people save a micro analysis of motives for household saving in japan this paper estimates the contribution of net saving for each of twelve motives to overall household saving in japan using micro data from a japanese government survey and finds that net saving for the retirement and precautionary motives both of which are consistent with the life cycle model are of dominant importance it also finds that the saving motives of japanese households vary greatly by age and that they save at each life stage for motives that are appropriate for that life stage these findings suggest that the life cycle model is highly applicable in the case of japan

on the examination of non linear relationship between market structure and performance in the us manufacturing industry abstract this paper attempts to investigate the causal link between market structure and industry performance using a micro panel data set of usa manufacturing industries over the period 1958 2007 we employ a novel panel gmm model strongly accounting for endogenous regressors and threshold variable the empirical findings denote the existence of a non monotonic relationship between market structure and total factor productivity tfp our findings call for future research on the impact of market structure on consumer welfare

a new method of estimating risk aversion i show existing evidence on labor supply behavior places an upper bound on risk aversion in the expected utility model i derive a formula for the coefficient of relative risk aversion in terms of the ratio of the income elasticity of labor supply to wage elasticity and degree of complementarity between consumption and labor i bound the degree of complementarity using data on consumption choices when labor supply varies across states using labor supply elasticity estimates i find a mean estimate of 1 then show generating 2 requires that wage increases cause sharper labor supply reductions jel d81 j22

leaving home as a self selection device we develop a model of intergeneratioal coresidence and transfers within the family in a setting of asymmetric information following an exchange motive altruistic parents receive services from their children who may make them financial gifts in return however parents do not know the privacyc ost to children of home sharing hence they make additional transfers in order to discipline their children and give them incentives to reveal their true privacy cost we show that only children who stay at the parental home receive an informational rent and that this rent is greaterf or recipients with a low privacy cost

habit formation in consumer preferences evidence from panel data this paper tests for the presence of habit formation using household data a simple model of habit formation implies a condition relating the strength of habits to the evolution of consumption over time when the condition is estimated with food consumption data from the panel study on income dynamics the results yield no evidence of habit formation at the annual frequency this finding is robust to a number of changes in the specification it also holds for several proxies for nondurables and services consumption created by combining psid variables with weights estimated from consumer expenditure survey data

assessing empirical approaches for analyzing taxes and labor supply recent surveys on the labor supply responses of men document a divergence in the estimates of substitution and income effects obtained using various estimation approaches generally studies accounting for nonlinear tax schedules in a static setting via a piecewise linear approach produce estimates that typically imply higher substitution and lower income responses than are suggested by empirical work applying other approaches this paper demonstrates that maximum likelihood estimation of a consumer choice problem with nonlinear budget sets implicitly relies on the satisfaction of inequality constraints that translate into behaviorally meaningful restrictions these constraints arise not as a consequence of economic theory but instead as a requirement to create a properly defined statistical model in the analysis of piecewise linear budget sets the implicit constraints required by maximum likelihood in estimation amount to imposition of slutsky conditions at all wage income combinations associated with kink points in the analysis of differentiable budget sets the tacit constraints invoked by maximum likelihood also involve inequality restrictions on slutsky terms the empirical work presented in this study supports the contention that these implicit constraints play a major role in explaining the discrepancies in estimates found in the literature on men s labor supply

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

the relative impact of inheritance and other factors on economic inequality an empirically grounded micro simulation of saving with bequests related negatively either in total to average children s income or separately to individual children s incomes is constructed for a single generation in a steady growth economy behavioral parameters are set so that predicted bequests to the next generation are consistent with both the scale and assignment of inheritances taken from a real world source for the simulation generation the relative impact of inheritance and other factors on different aspects of economic inequality is assessed while inheritance is a major cause of wealth inequality its influence on annual income and lifetime resources is small and in the latter case ambiguous inheritance perpetuates and may intensify inequalities arising originally from other causes in that sense it is a secondary cause of inequality but that is not of course to say that it is of secondary importance the extent of its influence on distribution remains an open question which cannot be decided merely by theoretical reasoning but requires in addition something in the nature of a quantitative analysis of the relevant facts wedgwood 1929 pp 60 61

bequest and wealth accumulation are some pieces of the puzzle missing the lively debate between laurence j kotlikoff and franco modigliani presented in the spring 1988 issue of this journal concerns an old question what is the main motivation for saving and therefore for the accumulation of wealth more specifically what are the respective contributions to aggregate wealth of 1 saving for retirement also known as hump saving 2 precautionary savings and unintended bequests due to uncertainty about the length of life and 3 planned bequests of course other wealth holding motives are possible but let us follow kotlikoff and modigliani in setting them aside for now if modigliani s life cycle hypothesis is to be viewed as a close to approximation of reality then the bulk of existing wealth should have resulted from some combination of hump and precautionary saving our comment on this dispute attempts to advance two issues first the controversy involves an enormous gap between empirical estimates of the share of inherited wealth in total accumulation even though the estimates are often based on the same data we hope to clarify why the estimates vary so widely second the kotlikoff modigliani dispute is presented as an american issue with little extension abroad we will present some results from other countries that bear on the controversy some of the estimates from kotlikofi s paper originated in a 1981 paper he wrote with lawrence summers which is why we sometimes refer to his position as the kotlikoff summers argument in this comment the problem of conceptualizing the contribution of bequest to aggregate savings can be summarized with a thought experiment assume all bequests were confiscated

on the long run evolution of inheritance france 1820 2050 this paper attempts to document and account for the long run evolution of inheritance we find that in a country like france the annual flow of inheritance was about 20 25 of national income between 1820 and 1910 down to less than 5 in 1950 and back up to about 15 by 2010 a simple theoretical model of wealth accumulation growth and inheritance can fully account for the observed u shaped pattern and levels using this model we find that under plausible assumptions the annual bequest flow might reach about 20 25 of national income by 2050 this corresponds to a capitalized bequest share in total wealth accumulation well above 100 our findings illustrate the fact that when the growth rate g is small and when the rate of return to private wealth r is permanently and substantially larger than the growth rate say r 4 5 vs g 1 2 which was the case in the 19th century and early 20th century and is likely to happen again in the 21st century then past wealth and inheritance are bound to play a key role for aggregate wealth accumulation and the structure of lifetime inequality contrarily to a widely spread view modern economic growth did not kill inheritance

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

the role of intergenerational transfers and life cycle saving in the accumulation of wealth he purpose of this paper is to review what economists know at present about the following question how large a portion of the existing wealth is the result of a bequest motive that is of accumulation for the specific purpose of leaving bequests i will also endeavor to clarify why an answer to this question is of interest in the early keynesian period when the study of national saving first attracted wide interest relatively little attention was paid to what led people to save though it was generally understood that the main systematic reason was to leave bequests j m keynes in the famous chapter 9 of the general theory of employment interest and money 1936 had listed seven distinct motives for saving besides the leaving of bequests but five of these which include to increase one s future income or to insure one s independence and power implied that all or nearly all the accumulation would finally wind up as bequeathed wealth this in turn meant that most private wealth originated through bequests that is it either had been received through bequests or was destined to be bequeathed and indeed how else could society accumulate wealth however keynes 1936 p 107 also mentioned two further motives precaution that is to build up a reserve against unforeseen contingencies and foresight that is to provide for an anticipated future relation between the income and the needs of the individual or his family different from that which exists in the present as for example in relation to old age family education or the maintenance of dependents these motives in contrast to most of the previous ones have the

competitive conditions and sectors productive efficiency a conditional non parametric frontier analysis abstract the scope of this paper is to build an appropriate nonparametric frontier framework by using time dependent conditional efficiency estimators to investigate how competition and time affect the process of technological change and technological catch up our empirical analysis utilizes a sample of 462 u s 6 digit manufacturing sectors over the period 1958 2009 contrary to the existing studies we apply the probabilistic approach of efficiency measurement to evaluate the dynamic effects alongside with the effects of competition on the sectors technological change and technological catch up levels moreover we estimate the sectors idiosyncratic efficiencies which are an approximation of solow s residual representing the unexplained part of the time dependent conditional measures the empirical results shed new light on the topic and signify that the dynamic effect of competitive conditions has a nonlinear effect on the sectors estimated performance specifically we unveil a u shaped curve between market concentration and technological change implying that the sectors higher concentration levels enhance their technological change levels e g innovation capacity having however a downsize effect on their technological catch up ability moreover the relationship between the sectors market concentration and technological catch up although non linear exhibits an n shaped curve with two turning points lastly the above findings remain robust when we limit our analysis to the capital intensive sectors

how inheriting affects bequest plans we present and test the idea that bequest planning is linked with the experience of inheriting we consider a family tradition of bequeathing as a channel through which the intention to bequeath is moulded by and is positively correlated with the experience of inheriting using data from the survey on health ageing and retirement in europe share we find that the experience of inheriting enhances the intention to bequeath independently of the positive impact of wealth we also find that the expectation of inheriting has a positive impact on the intention to bequeath controlling for the expected increase in wealth on account of future inheritances

does market structure affect labour productivity and wages evidence from a smooth coefficient semiparametric panel model this paper investigates the impact of market structure on labour productivity and wages using a panel data set of us manufacturing industries over the period 1958 2007 to account for nonlinear effects we employ a smooth coefficient semiparametric model scsm we find evidence in support of a nonlinear relationship between market concentration and labour productivity and wages lastly our empirical findings shed new light on the competition labour productivity nexus

is the effect of competition on price dispersion nonmonotonic evidence from the u s airline industry we investigate the effect of competition on price dispersion in the airline industry using panel data from 1993 to 2008 we find a nonmonotonic effect of competition on price dispersion an increase in competition is associated with greater price dispersion in concentrated markets but with less price dispersion in competitive markets an inverse u relationship our empirical findings are consistent with an oligopolistic second degree price discrimination model and encompass contradictory findings in the literature

risk aversion and expected utility theory a calibration theorem within the expected utility framework the only explanation for risk aversion is that the utility function for wealth is concave a person has lower marginal utility for additional wealth when she is wealthy than when she is poor this paper provides a theorem showing that expected utility theory is an utterly implausible explanation for appreciable risk aversion over modest stakes within expected utility theory for any concave utility function even very little risk aversion over modest stakes implies an absurd degree of risk aversion over large stakes illustrative calibrations are provided

life cycle individual thrift and the wealth of nations this paper provides a review of the theory of the determinants of individual and national thrift that has come to be known as the life cycle hypothesis lch of saving applications to some current policy issues are also discussed part i deals with the state of the art on the eve of the formulation of the lch some 30 years ago part ii sets forth the theoretical foundations of the model in its original formulation and later amendment calling attention to various implications distinctive to it and sometimes counter intuitive it also includes a review of a number of crucial empirical tests both at the individual and the aggregate level part iii reviews some applications of lch to current policy issues though only in sketchy fashion as space constraints prevent fuller discussion this abstract was borrowed from another version of this item

intergenerational transfers and savings in recent years the role of intergenerational transfers in the process of wealth accumulation has been the subject of substantial empirical and theoretical analysis the key question stimulating this research is what is the main explanation for savings is it primarily accumulation for retirement as claimed by albert ando richard brumberg and franco modigliani in their celebrated life cycle model of savings is it primarily intentional accumulation for intergenerational transfers or is it primarily precautionary savings much of which may be bequeathed because of imperfections in annuity markets this paper examines a range of findings on the importance of intergenerational transfers the strong conclusion that emerges from this evidence is that intergenerational transfers play a very important if not a key role in aggregate wealth accumulation while intergenerational transfers figure very large in savings the precise motivation for such transfers is unclear intergenerational altruism might appear the most likely candidate but at least sane stylized facts such as the equal allocation of bequests among children are strongly at adds with the altruism model other explanations involving imperfect insurance arrangements or payments for child services do not appear capable of explaining the substantial amounts of transfers actually observed sorting cut the relative contributions of different models to intergenerational transfers and the precise role of intergenerational transfers in the process of wealth accumulation remains an intriguing and exciting enterprise this abstract was borrowed from another version of this item

the effect of marginal tax rates on taxable income a panel study of the 1986 tax reform act this paper uses a treasury department panel of more than 4 000 taxpayers to estimate the sensitivity of taxable income to changes in tax rates on the basis of a comparison of the tax returns of the same individual taxpayers before and after the 1986 tax reform the analysis emphasizes that the response of taxable income involves much more than a change in the traditional measures of labor supply the evidence shows an elasticity of taxable income with respect to the marginal net of tax rate that is at least one and could be substantially higher the implications for recent tax rate changes are discussed

the role of intergenerational transfers in aggregate capital accumulation this paper uses historical u s data to directly estimate the contribution of intergenerational transfers to aggregate capital accumulation the evidence presented indicates that intergenerational transfers account for the vast majority of aggregate u s capital formation only a negligible fraction of actual capital accumulation can be traced to life cycle or hump savings a major difference between this study and previous investigations of this issue is the use of more accurate longitudinal age earnings and age consumption profiles these profiles are simply too flat to generate substantial life cycle savings this paper suggests the importance of and need for substantially greater research and data collection on intergenerational transfers life cycle models of savings that emphasize savings for retirement as the dominant form of capital accumulation should give way to models that illuminate the determinants of intergenerational transfers

the effect of income taxes on household income research on the distribution of income during the 1980s has identified a trend towards increasing inequality which may be the continuation and acceleration of trends spanning several decades this paper explores to what extent behavioral responses to the tax changes during the 1980s may also explain the rising inequality the 1986 tax reform act is used as a natural experiment to explore the roles played by both taxes and a variety of nontax factors our principal finding is that both tax rates and nontax factors appear to have had significant effects on relative income growth during the late 1980s

economists views about parameters values and policies survey results in labor and public economics specialists in labor economics and public economics at 40 leading research universities provided opinions of policy proposals quantitative best estimates and 95 percent confidence intervals for economic parameters and answers to values questions regarding income redistribution efficiency versus equity and individual versus social responsibility their positions on policy are more closely related to their values than to their estimates of relevant economic parameters average best estimates of the economic parameters agree well with the relevant literature but individual best estimates are usually widely dispersed the individual 95 percent confidence intervals are much narrower than the substantial cross respondent variation in estimates would warrant

developments in non expected utility theory the hunt for a descriptive theory of choice under risk this article reviews recent developments in the economic theory of individual decision making under risk since the 1950s it has been known that individual choices violate the standard model of expected utility in predictable ways considerable research effort has now been devoted to the project of developing a superior descriptive model following an overview of non expected utility theories which distinguishes between conventional and non conventional approaches the paper seeks to assess these alternative models in terms of empirical success using laboratory and field data and theoretical usefulness the closing sections reflect on some new directions emerging in this literature

a simple test of consumption insurance are consumers effectively insured against idiosyncratic shocks to income or wealth either by formal institutions such as charities private insurance and government programs or by informal mechanisms such as gifts and loans from relatives friends and neighbors under full insurance consumption growth should be cross sectionally independent of idiosyncratic variables that are exogenous to consumers this proposition is tested by cross sectional regressions of consumption growth on a variety of exogenous variables full insurance is rejected for long illness and involuntary job loss but not for spells of unemployment loss of work due to strike and an involuntary move

children and household economic behavior this paper looks at some of the methodological issues that arise in modeling the effects of children on household behavior and presents some estimates for selected areas for our purposes household behavior will be taken to refer to household decisions on labor supply the allocation of expenditure to different periods and the decision as to what to do with the difference between income and expenditure i shall be concerned mainly with the effects of dependent children and i restrict attention largely to western societies excerpt

what accounts for the variation in retirement wealth among u s households even among households with similar socioeconomic characteristics saving and wealth vary considerably life cycle models attribute this variation to differences in time preference rates risk tolerance exposure to uncertainty relative tastes for work and leisure at advanced ages and income replacement rates these factors have testable implications concerning the relation between accumulated wealth and the shape of the consumption profile using the panel study of income dynamics and the consumer expenditure survey we find little support for these implications the data are instead consistent with rule of thumb mental accounting or hyperbolic discounting theories of wealth accumulation jel di d91 e21

choice under uncertainty problems solved and unsolved ffifteen years ago the theory of choice under uncertainty could be considered one of the success stories of economic analysis it rested on solid axiomatic foundations it had seen important breakthroughs in the analytics of risk risk aversion and their applications to economic issues and it stood ready to provide the theoretical underpinnings for the newly emerging information revolution in economics 1 today choice under uncertainty is a field in flux the standard theory is being challenged on several grounds from both within and outside economics the nature of these challenges and of our profession s responses to them is the topic of this paper

tax avoidance and the deadweight loss of the income tax traditional analyses of the income tax greatly underestimate deadweight losses by ignoring its effect on forms of compensation and patterns of consumption the full deadweight loss is easily calculated using the compensated elasticity of taxable income to changes in tax rates because leisure excludable income and deductible consumption are a hicksian composite good microeconomic estimates imply a deadweight loss of as much as 30 of revenue or more than ten times harberger s classic 1964 estimate the relative deadweight loss caused by increasing existing tax rates is substantially greater and may exceed 2 per 1 of revenue

productivity growth and factor prices in east asia the industrial revolution in several east asian countries over the last three decades is one of the most important economic events in the postwar era several recent growthaccounting exercises have found that their extraordinary rate of output growth was due primarily to an equally impressive rate of factor accumulation with little due to technological progress see alwyn young 1992 1995 jong il kim and lawrence lau 1994 susan collins and barry bosworth 1996 since these studies suggest that factor accumulation has been the lead actor in east asia s growth many economists have reached the conclusion that the industrial revolution in east asia can largely be explained in terms of transition dynamics in a neoclassical growth framework see e g paul krugman 1994 n gregory mankiw 1995 if this view is correct the lesson from east asia s experience is that there are no easy solutions for a poor country that seeks to join the league of wealthy nations low levels of investment and education may be the result of bad policies but once proper policies are enacted a poor country faces the grim prospect of a further decline in its already low standards of living as it devotes more resources to investment and education the central point of this paper is that if east asia s growth was largely driven by capital accumulation with little technological progress the return to capital should have fallen dramatically as capital accumulation encounters diminishing returns for example the capital output ratio for korea computed from the national accounts has increased at an average rate of 3 4 percent per year from 1966 to 1990 while that of singapore has increased at an average rate of 3 7 percent per year from 1968 to 1990 by dividing the share of payments to capital in total income by the capital output

family transfers involving three generations most models of family transfers consider only two generations and focus on two motives altruism and exchange they also assume perfect substitution between inter vivos downward transfers and bequests based on french evidence we show that parent to child transfers belong to three distinct categories investment in child s education financial assistance wealth transmission and advocate a three generation framework thus transfer behavior of parents toward their children is strongly influenced by the behavior of their own parents there is also some evidence of the cox and stark demonstration effect parents help their own parents expecting to receive comparable support from their children such behavior can be regarded as indirect reciprocity the beneficiary does not give back to the initial giver but to a third person of another generation jel classification d10 d31 d63 d64

insuring consumption against illness one of the most sizable and least predictable shocks to economic opportunities in developing countries is major illness we investigate the extent to which families are able to insure consumption against major illness using a unique panel data set from indonesia that combines excellent measures of health status with consumption information we find that there are significant economic costs associated with major illness and that there is very imperfect insurance of consumption over illness episodes these estimates suggest that public disability insurance or subsidies for medical care may improve welfare by providing consumption insurance

uncertain lifetime consumption and dissaving in retirement this paper asks whether the continued accumulation or mild dissaving observed among the retired can be explained by uncertain lifetime in the absence of annuities after an initial period influenced by borrowing constraints under constant relative risk aversion uncertain lifetime depresses consumption by a proportion increasing with age if the elasticity of intertemporal substitution in consumption is small illustrative computations based on actual income and survival data show that plausible elasticities are sufficiently small to give this effect the reduction in consumption is large enough to explain much of the lack of decumulation by the elderly

the labor supply effects of the social security earnings test the social security earnings test taxes away benefits at a 33 50 rate once earnings pass a threshold amount i investigate the response to three past changes in the earnings test rules each applying to some age groups and not others i find that beneficiaries bunch in substantial numbers just below the earnings threshold and the bunching shifts when the earnings test rules change these shifts in the budget constraint are incorporated into an econometric model to identify income and substitution effects the estimation yields significant elasticities that suggest considerable deadweight loss suffered by working beneficiaries

social norms and gift behavior theory and evidence from romania in many developing and transitional countries with limited public income redistribution inter household transfers in general and gifts in particular are sizable and very important we use unique romanian survey data that enables us to isolate pure gifts from other private transfers we explicitly focus on the importance of community wide social norms and find that they indeed play a major role for both the occurrence and the values of gifts more exactly our results suggest that the overall predominant gift motive among romanian households is a norm of reciprocity moreover this norm seems to be dominating for gifts to middle and high income households even though poor households receive to the same extent norms of both impure altruism and reciprocity tend to be important hence although the poor may not reciprocate gifts to the same extent as the rich they still receive since there is a social norm to give especially to the poor

intergenerational transfers and the accumulation of wealth h t ouseholds acquire wealth from two sources they save out of income they have earned and they receive transfers from other people the first method of wealth accumulation goes under the name of life cycle saving in which people save during their working lives and dissave after retirement the second involves either an inter vivos transfer that is a transfer between living people or a bequest a transfer that occurs at the death of the donor while inter vivos transfers and bequests will arise in dynastic models where preferences include a taste for the well being of one s descendents few empirical life cycle models reflect these concerns indeed a sharp debate has arisen over the ability of the simple life cycle model to explain observed wealth accumulation understanding the relative sizes of these sources of wealth accumulation affects a variety of issues for example the effects of government debt social insurance public transfer programs estate taxes and incentives for charitable giving depend to some extent on the magnitude and nature of private saving and transfers of wealth analyses of the inequality of wealth may depend on whether most of wealth is earned or received as transfers appropriate policies for encouraging private saving may look rather different depending on whether most saving is to be consumed later in life or passed along to the next generation finally evidence on transfer patterns relates to more fundamental

unemployment insurance benefit levels and consumption changes abstract we use a canadian survey of the unemployed to examine how household expenditures after a job loss respond to the level of income replacement provided by ui we isolate a liquidity constraint or transitory income effect from the permanent income shock of job loss and from the costs of working we find significant effects of varying the replacement ratio among the third of the sample who did not have assets at the job loss we conclude that the consumption smoothing benefit of ui is concentrated wholly on a sub group of the unemployed

the elasticity of taxable income evidence and implications abstract a central tax policy parameter that has recently received much attention but about which there is substantial uncertainty is the overall elasticity of taxable income we provide new estimates of this elasticity which address identification problems with previous work by exploiting a long panel of tax returns to study a series of tax reforms throughout the 1980s this identification strategy also allows us to provide new evidence on both the income effects of tax changes on taxable income and on variation in the elasticity of taxable income by income group we find that the overall elasticity of taxable income is approximately 0 4 the elasticity of real income not including tax preferences is much lower we estimate small income effects of tax changes on reported income implying that the compensated and uncompensated elasticities of taxable income are very similar we estimate that this overall elasticity is primarily due to a very elastic response of taxable income for taxpayers who have incomes above 100 000 per year who have an elasticity of 0 57 while for those with incomes below 100 000 per year the elasticity is less than one third as large moreover high income taxpayers who itemize are particularly responsive to taxation our estimates suggest that optimal tax structures may feature tightly targeted transfers to lower income taxpayers and a flat or even declining marginal rate structure for middle and high income taxpayers

consumption versus expenditure previous authors have documented a dramatic decline in food expenditures at the time of retirement we show that this is matched by an equally dramatic rise in time spent shopping for and preparing meals using a novel data set that collects detailed food diaries for a large cross section of u s households we show that neither the quality nor the quantity of food intake deteriorates with retirement status we also show that unemployed households experience a decline in food expenditure and food consumption commensurate with the impact of job displacement on permanent income these results highlight how direct measures of consumption distinguish between anticipated and unanticipated shocks to income whereas measures of expenditures obscure the distinction
