agriculture production versus biodiversity protection the impact of north south unconditional transfers the purpose of this paper is to explore whether international income transfers can improve or worsen the global level of biodiversity and global social welfare by changing the relative contributions to biodiversity protection and to agricultural production because of the public good nature of biodiversity warr s neutrality theorem suggests that such transfers may have no effects at all warr 1983 a model is developed based on the simplifying assumption that northern countries have little biodiversity whereas southern countries are endowed with natural capital in the form of generally unspoilt biodiversity rich land southern countries allocate optimally land and capital to two competing productive activities agriculture and eco tourism when transfers are organized from the north to the south we show that warr s neutrality theorem collapses transfers can either reduce or increase the natural capital in the south depending on some empirically verifiable hypotheses concerning the characteristics of the eco tourism and agricultural production functions in addition we demonstrate that welfare improvements can be obtained even with reductions in the level of biodiversity research highlights could international income transfers improve the levels of biodiversity and welfare a model is developed with a biodiversity poor north and an ecosystem rich south we show that north south transfers can either reduce or increase the natural capital and that welfare improvements can be obtained even with reductions in biodiversity

inflation and income inequality in a variety expansion growth model with menu costs abstract this study explores the effect of inflation on income inequality in a growth model with variety expansion and menu costs inflation is found to determine income inequality via both asset value and interest rates effects our numerical analyses show that higher inflation turns these effects negative stifling economic growth and mitigating income inequality

has consumption inequality mirrored income inequality we revisit to what extent the increase in income inequality since 1980 was mirrored by consumption inequality we do so by constructing an alternative measure of consumption expenditure using a demand system to correct for systematic measurement error in the consumer expenditure survey our estimation exploits the relative expenditure of high and low income households on luxuries versus necessities this double differencing corrects for measurement error that can vary over time by good and income we find consumption inequality tracked income inequality much more closely than estimated by direct responses on expenditures jel d31 d63 e21

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

a financial macro network approach to climate policy evaluation abstract existing approaches to assess the economic impact of climate policies tend to overlook the financial sector and to focus only on direct effects of policies on the specific institutional sector they target neglecting possible feedbacks between sectors thus underestimating the overall policy effect to fill in this gap we develop a methodology based on financial networks which allows for analyzing the transmission throughout the economy of positive or negative shocks induced by the introduction of specific climate policies we apply the methodology to empirical data of the euro area to identify the feedback loops between the financial sector and the real economy both through direct and indirect chains of financial exposures across multiple financial instruments by focusing on climate policy induced shocks that affect directly either the banking sector or non financial firms we analyze the reinforcing feedback loops that could amplify the effects of shocks on the financial sector and then cascade on the real economy our analysis helps to understand the conditions for virtuous or vicious cycles to arise in the climate finance nexus and to provide a comprehensive assessment of the economic impact of climate policies

a unified measure of fed monetary policy shocks abstract we develop a u s monetary policy shock series that stably bridges periods of conventional and unconventional policymaking is largely unpredictable and contains no significant central bank information effect we attribute differences between our measure and often used alternatives to our econometric procedure a partial least squares approach and our using the full maturity spectrum of interest rates in estimating the shock we find that shocks to our monetary policy series have particularly large effects on maturities in the middle of the term structure and produce conventionally signed impulse responses of output and inflation

measuring uncertainty and its impact on the economy we propose a new framework for measuring uncertainty and its effects on the economy based on a large var model with errors whose stochastic volatility is driven by two common unobservable factors representing aggregate macroeconomic and financial uncertainty the uncertainty measures can also influence the levels of the variables so that contrary to most existing measures ours reflect changes in both the conditional mean and volatility of the variables and their impact on the economy can be assessed within the same framework moreover identification of the uncertainty shocks is simplified with respect to standard var based analysis in line with the favar approach and with heteroskedasticity based identification finally the model which is also applicable in other contexts is estimated with a new bayesian algorithm which is computationally efficient and allows for jointly modeling many variables while previous var models with stochastic volatility could only handle a handful of variables empirically we apply the method to estimate uncertainty and its effects using us data finding that there is indeed substantial commonality in uncertainty sizable effects of uncertainty on key macroeconomic and financial variables with responses in line with economic theory

durable goods an explanation for their slow adjustment at the microeconomic level durable purchases are often discontinuous and relatively large this feature has the potential to explain why aggregate expenditure on durables responds only slowly relative to the frictionless permanent income model to wealth and other aggregate innovations in this paper i develop new results on the problem of dynamic aggregation of stochastically heterogeneous units which help to characterize the connection between microeconomic behavior and aggregate dynamics in the presence of nonconvex adjustment costs using these results and splitting postwar u s aggregate durable purchases into different subcategories and time periods i provide further support for the view that lumpy microeconomic purchases play an important role in explaining the time series behavior of aggregate expenditure on durable goods

who bears aggregate fluctuations and how the consumption of high consumption households is more exposed to fluctuations in aggregate consumption and income than that of low consumption households in the consumer expenditure cex survey the exposure to aggregate consumption growth of households in the top 10 percent of the consumption distribution in the cex is about five times that of households in the bottom 80 percent given real aggregate per capita consumption growth about 3 percentage points less than its historical mean during the past year these figures predict that the ratio of consumption of the top 10 percent to the bottom 80 percent has fallen by about 15 percentage points relative to trend using income data from piketty and saez 2003 we show that the income especially the wage income of rich households is more exposed to aggregate fluctuations so their higher income exposure is a likely contributor to their higher consumption exposure finally we find a striking change in the exposure of the incomes of high income households prior to the early 1980 s the incomes of high income households were not more exposed to aggregate fluctuations thus while high income households currently bear an inordinately large share of aggregate fluctuations this is a recent occurrence this abstract was borrowed from another version of this item

interest rate prominence in consumer decision making variations in consumers responsiveness to interest rates across households and over time have important implications for monetary transmission responses from the michigan survey of consumers provide an indication of the degree to which interest rates are a prominent consideration in spending decisions news recollection and financial situations prominence is strongest in housing attitudes increases with income education and homeownership and declined in the great recession rate prominence is associated with stronger responsiveness of consumption attitudes to monetary policy jel d84 d91 e21 e40 e50

monetary policy and wealth inequality over the great recession in the uk an empirical analysis abstract we use detailed micro information at household level from the wealth and assets survey to construct measures of wealth inequality from 2006 to 2018 at the monthly frequency we investigate the dynamic relationship between monetary policy and the evolution of wealth inequality measures our findings suggest that expansionary monetary policy shocks lead to an increase in wealth inequality and contributed significantly to its fluctuations this effect is heterogenous across the wealth distribution with the monetary shock affecting the median household relative to the 10th and 20th percentile by a larger amount than the right tail our results suggest that the shock is transmitted through changes in net property and financial wealth

are consumers forward looking evidence from fiscal experiments how changes in current and future income affect consumer spending is a perennial question in macroeconomics and public finance theoretical constructs such as the permanent income hypothesis are of limited assistance in resolving this issue because they neglect borrowing constraints and other market imperfections that can significantly affect the marginal propensity to spend out of current income recent empirical work has also proven inconclusive since whether consumption responds to income fluctuations by more or less than the permanent income hypothesis predicts turns critically upon whether disposable income follows a random walk or is stationary around a longrun trend see john campbell and angus deaton 1987 this controversy is unlikely to be resolved conclusively because it is notoriously difficult to distinguish a stationary but highly persistent time series from one that is nonstationary these difficulties suggest the importance of searching for natural experiments income shocks with predictable and well understood effects on future income to test models of consumer behavior changes in federal tax and transfer policy during the last two decades provide several episodes of this type analyzing the effects of these tax changes is also central to understanding the role of fiscal policy in affecting national saving this paper examines two aspects of consumer response to tax changes section i argues that consumption responds to temporary income tax shocks by more than the permanent income hypothesis would suggest results from the 1975 tax rebate in particular suggest that a 1 increase in transitory income raises spending by about 20 cents section ii examines consumption responses to tax announcements although the results are not conclusive they suggest that some consumers do not adjust consumption in anticipation of tax changes the final section sketches some implications for analyzing fiscal policy

what can survey forecasts tell us about information rigidities a lot we derive common and conflicting predictions from models in which agents face information constraints and then assess their validity using surveys of consumers firms central bankers and professional forecasters we document that mean forecasts fail to completely adjust on impact to shocks leading to statistically and economically significant deviations from the null of full information the dynamics of forecast errors after shocks are consistent with the predictions of models with information rigidities the conditional responses of forecast errors and disagreement among agents can also be used to differentiate between some of the most prominent models of information rigidities

social security benefits consumption expenditure and the life cycle hypothesis this paper examines the impact of changes in social security benefits on aggregate consumption expenditure under the null hypothesis there should be no contemporaneous effect at the monthly frequency because increases in benefits have always been announced at least 6 weeks prior to payment the paper develops overwhelming evidence contrary to the null that benefits have affected aggregate spending the results have strong implications for several important issues including ricardian equivalence government policy irrelevance and the excess sensitivity of consumption to changes in income

did japan s shopping coupon program increase spending abstract in march 1999 31 million shopping coupons worth 20 000 yen each were distributed to japanese families with children and to the elderly the coupons expired after six months and could only be used within the recipient s local community we use variation in the number of children across families and in the number of recipients across prefectures to measure the effect of the coupons on spending we find that coupons had a positive effect on spending on semi durables but no effect on spending on nondurables or services the marginal propensity to consume on semi durables was 0 1 0 2 when the coupons were distributed in march the results using regional variation provide stronger evidence that spending did not fall after the coupons had been redeemed

the sensitivity of consumption to transitory income estimates from panel data on households we investigate the stochastic relation between income and consumption specifically consumption of food within a panel of about 2 000 households our major findings are 1 consumption responds much more strongly to permanent than to transitory movements of income 2 the response to transitory income is nonetheless clearly positive 3 a simple test independent of our model of consumption rejects a central implication of the pure life cycle permanent income hypothesis the observed covariation of income and consumption is compatible with pure life cycle permanent income behavior on the part of80 percent of families and simple proportionality of consumption and income among the remaining 20 percent as a general matter our findings support the view that families respond differently to different sources of income variations in particular temporary income tax policies have smaller effects on consumption than do other more permanent changes in income of the same magnitude this abstract was borrowed from another version of this item

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 drivers of income inequality in rich countries rising income inequality has recently come centre stage as a core societal concern for rich countries the diagnosis of the forces driving inequality upwards and their relative importance remains hotly contested notably with respect to the roles of globalization versus technology and of market forces versus institutions and policy choices this survey provides a critical review and synthesis of recent research the focus is on income inequality across the entire distribution rather than only on what has been happening at the very top we pay particular attention to including what has been learned from the analysis of micro data to ensuring that the coverage is not unduly us centric and to analyses of the interrelations between the different drivers of inequality the marked differences in inequality trends across countries and time periods reflect how global economic forces such as globalisation and technological change have interacted with differing national contexts and institutions major analytical challenges stand in the way of a consensus emerging on the relative importance of different drivers in how income inequality has evolved in recent decades

fiscal policy with heterogeneous agents and incomplete markets i undertake a quantitative investigation into the short run effects of changes in the timing of proportional income taxes for model economies in which heterogeneous households face a borrowing constraint temporary tax changes are found to have large real effects in the benchmark model a temporary tax cut increases aggregate consumption on impact by around 29 cents for every dollar of tax revenue lost comparing the benchmark incomplete markets model to a complete markets economy income tax cuts provide a larger boost to consumption and a smaller investment stimulus when asset markets are incomplete copyright 2005 wiley blackwell

inflation and income inequality in a schumpeterian economy with menu costs abstract this study incorporates heterogeneous households into a monetary schumpeterian growth model via menu costs to explore the effect of inflation on income inequality the source of income inequality stems from the unequal distribution across households assets given that households face the same wage rate inflation that leads to a monotonically decreasing effect on economic growth helps mitigate income inequality by weakening the contribution of asset income relative to wage income

monetary policy inequality and political instability voters in the industrialised countries are increasingly expressing dissatisfaction by dissenting from the established political parties and candidates based on the concepts of justice by hayek rawls and buchanan we argue that the growing dissatisfaction is rooted in the asymmetric pattern of monetary policies since the mid 1980s for two reasons first the structurally declining interest rates and the unconventional monetary policy measures have granted privileges to specific groups second the increasingly expansionary monetary policies have negative growth effects which have reduced the scope for compensation of the ones excluded from the privileges as a result the acceptance of the prevailing economic and political order is undermined and political instability increases

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

in praise of inequality public good provision and income distribution abstract it is shown that if all individuals contribute towards the provision of a public good their utilities are equalised even if the income distribution is unequal it may seem that there is then no role for redistributive policy but it is proved that social welfare can be raised by creating sufficient income inequality that only the rich provide public goods

how quantitative easing works evidence on the refinancing channel we document the transmission of large scale asset purchases by the federal reserve to the real economy using rich borrower linked mortgage market data and an identification strategy based on mortgage market segmentation we find that central bank qe1 mbs purchases substantially increased refinancing activity reduced interest payments for refinancing households led to a boom in equity extraction and increased aggregate consumption relative to qe ineligible jumbo mortgages qe eligible conforming mortgage interest rates fell by an additional 40 bp and refinancing volumes increased by an additional 56 during qe1 we estimate that households refinancing during qe1 increased their durable consumption by 12 our results highlight that the transmission of unconventional monetary policy to the real economy depends crucially on the composition of assets purchased and the degree of segmentation in the marke

robust determinants of income inequality while economic theory suggests a wide range of potential determinants of income inequality there is little consensus regarding the most relevant ones such a lack of consensus reflects to an important extent the impact of model uncertainty using model averaging techniques specifically wals weighted average least squares to get at a robust set of determinants our results underscore the multiplicity of factors behind rising national level inequalities in the cross section the level of development and demographics as well as unemployment and globalization seem to be key drivers trade and financial globalization have asymmetric effects with trade integration associated with lower inequality and financial globalization with higher inequality financial deregulation and technological change seem to be important drivers of inequality particularly in advanced economies

requiem for the representative consumer aggregate implications of microeconomic consumption behavior macroeconomists pursuing microfoundations for aggregate consumption have generally adopted one of two approaches either to model microeconomic consumption behavior carefully and then to aggregate or to thoroughly understand the behavior of a representative consumer in general equilibrium then to introduce microeconomic risk and heterogeneity the broad conclusion from the bottom up approach has been that precautionary saving and microeconomic heterogeneity can profoundly change behavior stephen p zeldes 1989 angus s deaton 1991 christopher d carroll 1992 the broad conclusion from the top down approach has been that precautionary saving is of little importance in determining the aggregate capital stock s rao aiyagari 1994 per krusell and anthony a smith 1998 leading some economists to conclude that heterogeneity is unimportant for macroeconomic purposes this paper shows that while general equilibrium effects do imply that the aggregate magnitude of precautionary saving is modest nevertheless when a model with uninsurable idiosyncratic risk is modified so that it can match the key micro facts it produces behavior very different in important respects from that produced by the representative agent economy this leads to the conclusion that for many purposes the representative consumer model should be abandoned in favor of a model which matches key microeconomic facts this abstract was borrowed from another version of this item

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

inequality leverage and crises the paper studies how high leverage and crises can arise as a result of changes in the income distribution empirically the periods 1920 1929 and 1983 2007 both exhibited a large increase in the income share of the rich a large increase in leverage for the remainder and an eventual financial and real crisis the paper presents a theoretical model where these features arise endogenously as a result of a shift in bargaining powers over incomes a financial crisis can reduce leverage if it is very large and not accompanied by a real contraction but restoration of the lower income group s bargaining power is more effective

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

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

changes in the federal reserve s inflation target causes and consequences this paper estimates a new keynesian model to draw inferences about the behavior of the federal reserve s unobserved inflation target the results indicate that the target rose from 1 1 4 percent in 1959 to over 8 percent in the mid to late 1970s before falling back below 2 1 2 percent in 2004 the results also provide some support for the hypothesis that over the entire postwar period federal reserve policy has systematically translated short run price pressures set off by supply side shocks into more persistent movements in inflation itself although considerable uncertainty remains about the true source of shifts in the inflation target jel e31 e32 e52

common and country specific factors in the distribution of real wages abstract we use a dynamic factor model to consider if real wage growth in the us uk and germany at different percentiles of the distribution can be explained by factors that are common across countries or specific to each country our results suggest that common factors explain a large proportion of the movement in wages when considering the left tail of the distribution indicating that shocks that are common across countries are important for low wage households

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

the heterogeneous impact of monetary policy on the us labor market abstract we empirically investigate the role of central banks in the context of heterogeneous labor markets jobless recoveries and job polarization specifically we estimate the effect of monetary policy on the us labor market using disaggregated time series based on large scale survey data the impact of interest rate changes on unemployment in 32 occupation groups is explored in a bayesian factor augmented vector autoregression framework the results suggest largely heterogeneous impacts across various occupation groups this heterogeneity can be explained by differential task profiles of the workers in their respective occupations workers with tasks that are easily automated or offshored as well as workers at the bottom of the skill distribution are disproportionately affected following a monetary policy shock this implies that labor market participants that are highly vulnerable to structural developments such as skill biased technological change and the globalization of labor markets are also most sensitive to conventional monetary policy measures from a policy perspective we conclude that central banks are unlikely to be able to take on a stabilizing role in the context of labor market polarization

banks leverage behaviour in a two agent new keynesian model abstract we study the distributive effects of a negative shock to banks assets in a saver capitalist model we analyze how this kind of heterogeneity affects macroeconomic variables and the distribution between savers and capitalists through banks leverage procyclicality the distributive effects are non favourable to savers and long lasting lower risk aversion of capitalists strengthens and lengthens the procyclicality of leverage leading to a lower decrease of savers income and consumption whilst stricter regulatory requirements are favourable to savers a tougher inflation targeting is unfavourable to savers the model is robust to the combined introduction of labour market frictions and hysteresis which together generate an amplification and lengthening of the recessionary and distributive effects unfavourable to savers

how prudent are consumers using data from the consumer expenditure survey this paper presents a simple test that provides an explicit estimate of the parameter in the utility function that reflects the strength of the precautionary saving motive the coefficient of relative prudence the test yields a fairly precise estimate of a small precautionary motive in fact the estimate is too small to be consistent with widely accepted beliefs about risk aversion the presence of liquidity constrained households does not appear to explain this finding and there is some evidence that self selection of households into risky environments also cannot explain the results

price stickiness along the income distribution and the effects of monetary policy abstract monetary shocks have distributional consequences if they affect relative prices across goods consumed by different households we document that the prices of the goods consumed by high income households are stickier and less volatile than those of the goods consumed by middle income households following a monetary policy shock the estimated impulse responses of high income households consumer price indices are about one third smaller than those of the middle income households we evaluate the implications of these findings in a quantitative multi sector new keynesian model featuring heterogeneous households the distributional consequences of monetary policy shocks are large and similar to those in the econometric model

unanticipated aggregate disturbances and tests of the life cycle consumption model several recent studies have used data on food consumption from the panel study of income dynamics psid to test t he rational expectations life cycle hypothesis against the alternative of prevalent liquidity constraints these tests invoke the rational expectations restriction that income forecast errors are independent of lagged information this restriction however applies only in a time series context it is possible that unanticipated macroeconomic disturbances cause forecast errors to be correlated with lagged information in a cross section of families the authors present evidence of such a correlation in the psid data show that this correlation biases previous tests of the life cycle model toward rejection and derive a proper test of the life cycle model using pa nel data copyright 1993 by mit press

consumer response to the reagan tax cuts abstract this paper uses micro data from the consumer expenditure survey to estimate the response of household consumption to the second and third phases of the reagan tax cuts since these phases were pre announced they allow for an unusually clean test of the canonical life cycle permanent income model consumption is found to be excessively sensitive to the tax cuts counter to the model liquidity constraints and other standard explanations do not appear to explain this excess sensitivity the consumption response is larger than previously estimated for tax refunds and more concentrated in nondurables these differences have important implications for the structure of tax changes in particular for choosing between varying withholding rates versus varying lumpy final tax payments and refunds

the distributional effects of conventional monetary policy and quantitative easing evidence from an estimated dsge model abstract this paper compares the distributional effects of conventional monetary policy and quantitative easing qe within an estimated open economy dsge model of the euro area the model includes two groups of households i wealthier households who own financial assets and are able to smooth consumption over time and ii poorer households who only receive labor and transfer income and live hand to mouth we use the model to compare the impact of policy shocks on constructed measures of income and wealth inequality net disposable income net asset position and relative per capita income except for the short term expansionary conventional policy and qe shocks tend to mitigate income and wealth inequality between the two population groups in light of the coarse dichotomy of households that abstracts from richer income and wealth dynamics at the individual level the analysis emphasizes the functional distribution of income

comparative statics by adaptive dynamics and the correspondence principle the intuition behind comparative statics results is usually dynamic in nature the economic explanation for why differences in endogenous variables result from variations in exogenous variables often takes the form of some sequential adjustment process for example consider the account by milgrom qian and roberts 1991 of technological and organizational changes in modern manufacturing the falling costs of high speed data communication data processing and flexible multitask equipment lead to increases in the directly affected activities which through a web of complementarities then lead to increases in a set of related activities as well despite the prevalence of dynamic economic explanations the formal analysis is static in games of strategic complementarities gsc topkis 1979 vives 1990 parameterized by a variable that is complementary to the choice variables the existing results on monotone comparative statics of equilibria are summarized by a theorem of milgrom and roberts 1990 mr hereafter the largest and smallest equilibria in a parameterized gsc

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

dyke maintenance and other stories some neglected types of public goods the orthodox summation model of a pure nonexcludable public good assumes that each individual consumes a quantity of public good defined as the sum of all individuals contributions to that good recently hirshleifer 1983 1985 has analyzed models that do not fall within this class at one extreme is the weakestlink in which the total quantity available to each consumer equals the smallest individual contribution at the other is the best shot in which the total quantity available equals the largest individual contribution hirshleifer s example of the weakest link case concerns a circular region of which each citizen owns a pie shaped slice the perimeter is marked by a dyke floods may penetrate the weakest point of the dyke and cause damage equally throughout the region each citizen decides the height and state of repair of that section of the dyke adjoining his piece of land its maintenance constituting his contribution to the public good thus the level of protection enjoyed by all is determined by the least well maintained section of the dyke an example of the best shot case concerns a number of antimissile batteries ringing a city firing at an incoming icbm all that matters is the accuracy of the best shot bliss and nalebuff 1984 discuss dragon slaying as another example of a best shot situation section ii of this paper introduces a class of functions of which the summation weakest link and best shot are examples section iii analyzes the properties of equilibrium when consumers have identical tastes and incomes section iv analyzes the implications of income redistribution in the summation case the equilibrium is unaffected by the initial redistribution over a range and outside that range transfers help the recipient and hurt the donor within the broader class of models however the invariance property does not generally hold and there may be opportunities for paretoimproving income redistribution i give an example similar to the weakest link case in which a pareto improving redistribution is

testing for liquidity constraints in euler equations with complementary data sources previous tests for liquidity constraints using consumption euler equations have frequently split the sample on the basis of wealth arguing that low wealth consumers are more likely to be constrained we propose alternative tests using different and more direct information on borrowing constraints obtained from the 1983 survey of consumer finances in a first stage we estimate probabilities of being constrained which are then utilized in a second sample the panel study of income dynamics to estimate switching regression models of the euler equation our estimates indicate stronger excess sensitivity associated with the possibility of liquidity constraints than the sample splitting approach

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

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

monetary policy natural resources and federal redistribution can monetary policy shocks induce redistribution across natural resource rich and poor states within a federation we conjecture that resource rich states are capital intensive hence their investment is more responsive to changes in monetary policy consequently contractionary monetary policy shocks e g increases in the interest rate may induce redistribution from resource poor states to resource rich ones via an equalizing federal transfer scheme because investment is reduced more strongly in the latter we test these hypotheses using a panel of u s states covering several decades and find that 1 resource rich states are significantly and persistently more capital intensive 2 contractionary monetary policy shocks induce a relative drop increase in investment federal transfers in resource rich states over the course of four years 3 these patterns are driven by resource induced differences in the capital share in the economy we estimate that a one standard deviation contractionary monetary shock induces within the first year federal redistribution of approximately 2 5 billion from the resource poor to the resource rich states representing about 11 of the total average annual federal transfers received by the latter states

on inflation as a regressive consumption tax abstract evidence on the portfolio holdings and transaction patterns of households suggests that the burden of inflation is not evenly distributed we build a monetary growth model consistent with key features of cross sectional household data and use this framework to study the distributional impact of inflation at the aggregate level our model economy behaves similar to standard monetary growth models within the representative agent abstraction inflation has however important distributional effects since it is effectively a regressive consumption tax thus neglecting the distributional consequences of inflation may prove misleading in assessing the effects of inflation in our economy

is consumption growth consistent with intertemporal optimization evidence from the consumer expenditure survey in this paper we show that some of the predictions of models of consumer intertemporal optimization are in line with the patterns of nondurable expenditure observed in u s household level data we propose a flexible specification of preferences that allows multiple commodities and yields empirically tractable equations we estimate preference parameters using the only u s micro data set with complete consumption information we show that previous rejections can be explained by the simplifying assumptions made in previous studies we also show that results obtained using good consumption or aggregate data can be misleading

finance inequality nexus the long and the short of it financial development affects income inequality differently in the short and in the long term investigating oecd countries from 1870 2011 we find in the short run an improvement in financial development tends to reduce inequality while in the long run more finance contributes to more inequality the short run effect concurs with theories advocating financial development increases the availability of financial services primarily for the poor however this effect becomes nil within a few years results thus imply that policies aimed at reducing inequality through improving access of the poor to finance need to be carefully designed to ensure longevity of impact

central bank policies and income and wealth inequality a survey this paper reviews recent research on the relationship between central bank policies and inequality a new paradigm which integrates sticky prices incomplete markets and heterogeneity among households is emerging which allows for the joint study of how inequality shapes macroeconomic aggregates and how macroeconomic shocks and policies affect inequality the new paradigm features multiple distributional channels of monetary policy most empirical studies however analyze each potential channel of redistribution in isolation our review suggests that empirical research on the effects of conventional monetary policy on income and wealth inequality yields mixed findings although there seems to be a consensus that higher inflation at least above some threshold increases inequality in contrast to common wisdom conclusions concerning the impact of unconventional monetary policies on inequality are also not clear cut to better understand policy effects on inequality future research should focus on the estimation of general equilibrium models with heterogeneous agents

impure public goods and transfers in a three agent model abstract this paper extends previous models of non cooperative private funding of pure public goods by allowing for impure public goods the analysis is developed in the context of international public goods under certain conditions the consequences of transfers on utility are paradoxical if the preferences are divergent a country may gain by giving a transfer the receiver may lose and these two phenomena may appear at the same time

no job no money no refi frictions to refinancing in a recession we study how employment documentation requirements and out of pocket closing costs constrain mortgage refinancing these frictions which bind most severely during recessions may significantly inhibit monetary policy pass through to study their effects on refinancing we exploit a federal housing administration policy change that excluded unemployed borrowers from refinancing and increased others out of pocket costs substantially these changes dramatically reduced refinancing rates particularly among the likely unemployed and those facing new out of pocket costs our results imply that unemployed and liquidity constrained borrowers have a high latent demand for refinancing cyclical variation in these factors may therefore affect both the aggregate and distributional consequences of monetary policy

heterogeneous consumers segmented asset markets and the real effects of monetary policy this paper proposes a novel mechanism by which changes in the distribution of money holdings have real effects specifically i develop a flexible price model of segmented asset markets that generates real aggregate effects of monetary policy through the dependence of optimal markups on the heterogeneity of money holdings because varieties of consumption bundles are purchased sequentially newly injected money disseminates slowly throughout the economy via second round effects the model predicts a short term inflation output trade off a liquidity effect countercyclical markups and procyclical wages after monetary shocks among other correlations of financial variables it also reproduces the empirical negative relationship between changes in the money supply and markups

bounded rationality lifecycle consumption and social security abstract this paper explores an overlapping generations model of bounded rationality in which consumers only foresee the future over a subset of their life span we focus in particular on whether the model can in general equilibrium produce a hump shaped lifecycle consumption profile with a peak that matches data for the average u s consumer for a simple four period model we show that an increasing income profile along with exogenously imposed retirement are sufficient to induce a hump with no other mechanism that can account for a hump besides bounded rationality the model best fits the salient features of consumption data with a planning horizon of 20 years which is well supported by the behavioral evidence found in surveys on retirement planning finally we show that the age of the consumption peak is robust to the introduction of social security mortality risk and another species of bounded rationality quasihyperbolic discounting moreover social security can be welfare improving with a short planning horizon we can calibrate the model to jointly explain the timing of the consumption hump and the optimality of the current social security system with quasihyperbolic discounting instead we can calibrate the model so the current social security system is optimal but we cannot also account for the timing of the consumption hump if we add quasihyperbolic discounting in addition to a short planning horizon the present bias has a negligible effect in equilibrium

the price effects of monetary shocks in a network economy abstract empirical evidence shows monetary shocks have two temporary effects on the distribution of prices one the dispersion of cross section of prices increases in response to monetary shocks two some prices change in the wrong direction some prices decrease in response to positive monetary shocks and increase in response to negative monetary shocks we present a model that generates the two effects of monetary shocks on the distribution of prices as an out of equilibrium phenomena firms are related to each other through a production network monetary shocks change the working capital of a subset of firms and percolate to other firms through buyer seller linkages price dispersion increases because the percolation of a monetary shock through the production network causes prices to differentially deviate from their steady state values some prices change in the wrong direction because a shift in one firm s demand causes a shift in another firm s supply and vice versa thereby generating complicated chains of bi directional price changes monetary shocks can significantly disturb relative prices even when all prices are fully flexible

innocent bystanders monetary policy and inequality abstract we study the effects of monetary policy shocks on and their historical contribution to consumption and income inequality in the united states since 1980 as measured by the consumer expenditure survey contractionary monetary policy systematically increases inequality in labor earnings total income consumption and total expenditures furthermore monetary policy shocks account for a non trivial component of the historical cyclical variation in income and consumption inequality using detailed micro level data on income and consumption we document some of the different channels via which monetary policy shocks affect inequality as well as how these channels depend on the nature of the change in monetary policy

permanent income current income and consumption evidence from two panel data sets in this article i estimate euler equations that is the first order conditions of the consumers maximization problem using data from two data sets consumption data are taken from the consumer expenditure survey income data are taken from the panel study of income dynamics because the data for the estimation come from two samples i use a generalization of the instrumental variables estimator the two sample instrumental variables estimator i find evidence that consumption is excessively sensitive to predictable income growth the estimates of the coefficient of excess sensitivity for three consumption measures range from 2 to 5

has u s monetary policy changed evidence from drifting coefficients and real time data despite the large amount of empirical research on monetary policy rules there is surprisingly little consensus on the nature or even the existence of changes in the conduct of u s monetary policy three issues appear central to this disagreement 1 the specific type of changes in the policy coefficients 2 the treatment of heteroskedasticity and 3 the real time nature of the data used this paper addresses these issues in the context of forwardlooking taylor rules with drifting coefficients the estimation is based on real time data and accounts for the presence of heteroskedasticity in the policy shock the findings suggest important but gradual changes in the rule coefficients not adequately captured by the usual split sample estimation in contrast to orphanides 2002 2003 i find that the fed s response to the real time forecast of inflation was weak in the second half of the 1970s perhaps not satisfying taylor s principle as suggested by clarida gali and gertler 2000 however the response to inflation was strong before 1973 and gradually regained strength from the early 1980s onward moreover as in orphanides 2003 the fed s response to real activity fell substantially and lastingly during the 1970s

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

perhaps the 1970s fomc did what it said it did briefing forecasts prepared for the federal open market committee fomc are used to estimate changes in the design of us monetary policy and in the implied policy target for inflation from 1970 through 1997 both estimated policy rate responses and fomc transcripts are consistent with intermediate targeting of monetary aggregates throughout the great inflation of the 1970s the unpublished fomc targets for m1 growth are tabulated empirical results support an effective inflation target of roughly 7 in the 1970s and 3 thereafter a notable difference in the 1970s monetary policies of the us and germany is the absence of explicit public objectives for us long run inflation

limited asset market participation and the euro area crisis an empirical dsge model we estimate a medium scale dynamic stochastic general equilibrium model for the euro area with limited asset market participation lamp our results suggest that in the recent european monetary union years lamp is particularly sizable 39 during 1993 2012 and important to understand business cycle features the bayes factor and the forecasting performance show that the lamp model is preferred to its representative household counterpart in the representative agent model the risk premium shock is the main driver of output volatility in order to match consumption correlation with output in the lamp model this role is played by the investment specific shock because non ricardian households introduce a keynesian multiplier effect and raise the correlation between consumption and investments we also detect the contractionary role of monetary policy shocks during the post 2007 years in this period consumption of non ricardian households fell dramatically but this outcome might have been avoided by a more aggressive policy stance jel c11 c13 c32 e21 e32 e37

consumer response to tax rebates many households received income tax rebates in 2001 of 300 or 600 these rebates represented advance payments of the tax cut from the new 10 percent tax bracket based on a survey of a representative sample of households this paper finds that only 22 percent of households receiving the rebate would spent it instead they would either save it or use it to pay off debt this very low rate of spending represents a striking break with past behavior which would have suggested a much higher rate of spending the low spending rate implies that the tax rebate provided a very limited stimulus to aggregate demand this abstract was borrowed from another version of this item

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

inequality and the business cycle evidence from u s survey data we study the effects of macroeconomic shocks on measures of economic inequality obtained from u s survey data to identify aggregate supply aggregate demand and monetary policy shocks we estima

employment prospects and the propagation of fiscal stimulus abstract this paper studies a mechanism that amplifies the effects of a rise in government purchases through private consumption fiscal stimulus increases aggregate demand boosts job creation and as a consequence improves job finding rates this in turn reduces individual unemployment risk faced by households decreases precautionary motives and crowds private spending in additionally higher job finding rates affect aggregate labor market flows which raises the ratio between employed and unemployed workers as the former feature higher spending than the latter then mechanically aggregate consumption increases a calibrated model with uninsured idiosyncratic risk frictional labor market and sticky prices is used to isolate and to quantify the joint impact of these two forces the so called employment prospects channel i find that when it is shut off the drop in the values of both impact and cumulative multipliers is substantial and ranges from 32 to 38 under various monetary and fiscal policy rules

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 respond to future income shocks evidence from social security reform in taiwan abstract a prediction of the basic permanent income hypothesis life cycle model is that an unexpected increase in future income produces an immediate increase in current consumption this paper tests that prediction using data from taiwan the 1985 labor standards law granted all employees in covered industries a windfall retirement severance benefit my results indicate that consumption did not increase immediately for those who were granted the windfall relative to those who received no windfall moreover consumption for those receiving a greater windfall did not increase relative to those who were granted less

the savers spenders theory of fiscal policy the macroeconomic analysis of fiscal policy is usually based on one of two canonical models the barro ramsey model of infinitely lived families or the diamond samuelson model of overlapping generations this paper argues that neither model is satisfactory and suggests an alternative in the proposed model some consumers plan ahead for themselves and their descendants while others live paycheck to paycheck this model is easier to reconcile with the essential facts about consumer behavior and wealth accumulation and it yields some new and surprising conclusions about fiscal policy

intertemporal choice and consumption mobility the theory of intertemporal consumption choice makes sharp predictions about the evolution of the entire distribution of household consumption not just about its conditional mean in the paper we study the empirical transition matrix of consumption using a panel drawn from the bank of italy survey of household income and wealth we estimate the parameters that minimize the distance between the empirical and the theoretical transition matrix of the consumption distribution the transition matrix generated by our estimates matches remarkably well the empirical matrix both in the aggregate and in samples stratified by education our estimates strongly reject the consumption insurance model and suggest that households smooth income shocks to a lesser extent than implied by the permanent income hypothesis jel d52 d91 i30

the role of automatic stabilizers in the u s business cycle most countries have automatic rules in their tax and transfer systems that are partly intended to stabilize economic uctuations this paper measures how eective they are at lowering the volatility of u s economic activity we identify seven potential stabilizers in the data and include four theoretical channels through which they may operate in a business cycle model calibrated to the u s data the model is used to compare the volatility of output in the data with counterfactuals where some or all of the stabilizers are shut down our rst nding is that proportional taxes like sales property and corporate income taxes contribute little to stabilization our second

assessing international commonality in macroeconomic uncertainty and its effects this paper uses a large vector autoregression var to measure international macroeconomic uncertainty and its effects on major economies using two datasets one with gdp growth rates for 19 industrialized countries and the other with a larger set of macroeconomic indicators for the u s euro area and u k using basic factor model diagnostics we first provide evidence of significant commonality in international macroeconomic volatility with one common factor accounting for strong comovement across economies and variables we then turn to measuring uncertainty and its effects with a large var in which the error volatilities evolve over time according to a factor structure the volatility of each variable in the system reflects time varying common global components and idiosyncratic components in this model global uncertainty is allowed to contemporaneously affect the macroeconomies of the included nations both the levels and volatilities of the included variables in this setup uncertainty and its effects are estimated in a single step within the same model our estimates yield new measures of international macroeconomic uncertainty and indicate that uncertainty shocks surprise increases lower gdp and many of its components adversely affect labor market conditions lower stock prices and in some economies lead to an easing of monetary policy
