macroeconomic impacts of oil price shocks in asian economies abstract this paper analyzes the macroeconomic impact of structural oil shocks in four of the top oil consuming asian economies using a var model we identify three different structural oil shocks via sign restrictions an oil supply shock an oil demand shock driven by global economic activity and an oil specific demand shock the main results suggest that economic activity and prices respond very differently to oil price shocks depending on their types in particular an oil supply shock has a limited impact while a demand shock driven by global economic activity has a significant positive effect in all four asian countries examined our finding also includes that policy tools such as interest rates and exchange rates help mitigating the effects of supply shocks in japan and korea however they can be more actively used in response to demands shocks

job displacement and financial outcomes abstract using two proprietary datasets on earnings and credit outcomes this paper finds that both high and low earners take a significant and persistent hit to income after job displacement but these losses only translate into worse credit conditions higher credit card utilization lower fico scores and a pick up in the rate of card accounts that are delinquent or over limit among low earners we observe no negative implications among higher income households providing novel empirical evidence of the economically disparate impact of job loss

income dynamics and life cycle inequality mechanisms and controversies this study focuses on the transmission of inequality over the working life a model of constrained intertemporal choice is used to provide structure to the distributional dynamics of wages earnings income and consumption the mechanisms used to insure labour market shocks are examined in a partial insurance setting where the manner and scope for insurance depends on the access to credit the information available to consumers and the durability of income shocks drawing on recent research family labour supply the credit market and the tax system are all shown to play a key role these mechanisms vary in importance across different points of the life cycle and the business cycle 2014 the author s the economic journal published by john wiley sons ltd on behalf of royal economic society

when do long run identifying restrictions give reliable results many recent articles have identified behavioral disturbances in vector autoregressions by imposing restrictions on the long run effects of shocks this article demonstrates that this approach will be unreliable unless the underlying economy satisfies three types of strong restrictions although many aspects of these issues have been raised before this article draws out and illustrates the implications for inferences under the long run scheme furthermore it provides strategies for dealing with the problems

prices output and the balance of payments in an open economy with rational expectations abstract the paper outlines an open economy version of the lucas competitive equilibrium rational expectations model it analyses the determination of output prices exports imports and the exchange rate under fixed and floating exchange rate regimes where information on the current exchange rate is used to infer the current values of foreign and domestic monetary shocks output is influenced by both foreign and domestic monetary shocks but independent of systematic foreign and domestic monetary growth under both exchange rate regimes flexible exchange rates insulate the domestic economy from systematic foreign monetary growth

consumption in the shadow of unemployment abstract by how much do employed households reduce their consumption when the aggregate unemployment rate rises in spain during the great recession a one point increase in the unemployment rate was related to a strong reduction in household consumption of more than 0 7 per equivalent adult this reduction is consistent with forward looking agents responding to downward revisions of their expectations on future income growth rates the shadow of unemployment using consumption panel data that include information on physical quantities we show that the drop in consumption expenditure was truly a reduction in quantities and not a switch to cheaper alternatives

price formation and liquidity in the u s treasury market the response to public information the arrival of public information in the u s treasury market sets off a two stage adjustment process for prices trading volume and bid ask spreads in a brief first stage the release of a major macroeconomic announcement induces a sharp and nearly instantaneous price change with a reduction in trading volume demonstrating that price reactions to public information do not require trading the spread widens dramatically at announcement evidently driven by inventory control concerns in a prolonged second stage trading volume surges price volatility persists and spreads remain moderately wide as investors trade to reconcile residual differences in their private views how do financial markets form prices and provide liquidity when information arrives efforts to address this issue have led to an extensive microstructure literature on equity markets and to a lesser extent on the foreign exchange fx market relatively little work has focused on the u s treasury market however in spite of its importance in its own right and the advantages it offers as an alternative testing ground for microstructure hypotheses

regime switching in the reactions of stock markets in saudi arabia to oil price variations the study revisits the stock oil nexus by examining the reactions of equity markets to oil price shocks at national and sectoral levels for saudi arabia in a time varying framework by employing the markov switching egarch model developed by henry 2009 journal of banking and finance 33 405 based on weekly data the findings reveal that the behaviour of all stock markets switches between an expansion regime and a recession regime with more persistence for the expansion state additionally influential international events associated with stock market drops are clearly identified in the recession regime furthermore there is evidence of asymmetric reactions of the equity index returns and the probabilities of transition from one state to another to oil price variations with heterogeneous impacts across sectors and regimes the stock markets are more sensitive to oil price decreases than to oil price increases although the evidence of relatively slight differences in some findings across weekdays the study allows investors and policymakers to understand well the interactions of stock sector markets vis a vis the world oil market in a regime switching framework in order to make the right decision as regards portfolio diversification and regulation of the stock markets

volatility spillovers between oil prices and stock sector returns implications for portfolio management abstract in this article we take a recent generalized var garch approach to examine the extent of volatility transmission between oil and stock markets in europe and the united states at the sector level the empirical model is advantageous in that it typically allows simultaneous shock transmission in the conditional returns and volatilities insofar as volatility transmission across oil and stock sector markets is a crucial element for portfolio designs and risk management we also analyze the optimal weights and hedge ratios for oil stock portfolio holdings with respect to the results our findings point to the existence of significant volatility spillover between oil and sector stock returns however the spillover is usually unidirectional from oil markets to stock markets in europe but bidirectional in the united states our back testing procedures finally suggest that taking the cross market volatility spillovers estimated from the var garch models often leads to diversification benefits and hedging effectiveness better than those of commonly used multivariate volatility models such as the ccc garch of bollerslev 1990 the diagonal bekk garch of engle and kroner 1995 and the dcc garch of engle 2002

understanding the costs of consumer durable adjustments this article examines whether adjustment frictions help account for the patterns of household consumption expenditures observed in the consumer expenditure survey namely that the variance of log durable expenditure is four times larger than that of log nondurable expenditure for annual data and this gap substantially widens for quarterly data estimating a structural model of household consumption with nondurable and durable goods with the simulated method of moments i find that the fixed costs associated with durable adjustments are important in matching the cross sectional moments using the estimated model i also examine the response of nondurable and durable expenditures to income shocks jel d12 d91 e21

saving and portfolio allocation before and after job loss we investigate the development of household labor income financial wealth and asset holdings over a 9 year period around job loss using unique administrative panel data from norway consistent with predictions from theory the data show additional saving and a shift toward safer assets in the years leading up to unemployment and depletion of savings after job loss in the years after job loss the households after tax labor income is reduced by about usd 12 500 over the same time period households deplete usd 3 000 of their financial assets of which one third is accumulated prior to the job loss this suggests that at least some households can foresee and prepare for the upcoming unemployment which indicates that private savings can to some extent serve as a substitute for publicly provided unemployment insurance

compensatory inter vivos gifts parents transfer motives are important for understanding e g macroeconomics income re distribution savings and public finance using data from six biennial waves of the health and retirement study 1992 2002 we estimate censored regression models with nested multilevel error components first we interpret our findings that inter vivos transfers from parents to children are gifts rather than temporary help to overcome liquidity constraints second inter vivos gifts are compensatory in the sense that lifetime poorer children will receive higher transfers than their lifetime richer siblings third inter vivos gifts do not however make up the entire difference in lifetime incomes copyright 2009 john wiley sons ltd

structural change and the macroeconomic effects of oil shocks empirical evidence from the united states and japan abstract this paper investigates whether the usa and japan have become better insulated from oil price disturbances due to more favorable structural conditions new production technologies allowing greater energy substitution the development of energy commodity markets reduced energy intensity of production more market oriented energy policies and so on we decompose the influences of oil shocks on real gnp growth and inflation movements in the context of a simultaneous equation model where identification is partly achieved by restricting the long run dynamics we find that oil shocks accounted for a greatly reduced fraction of real gnp growth and inflation variance in both countries primarily because of superior insulation characteristics rather than reduced importance of oil disturbances our estimates suggest that a similar percentage oil price hike would have exerted about one quarter the contractionary effect on real gnp and upward push in inflation in the 1980s compared with the previous two decades jel e31 e32 f30

empirical evidence on the insulation properties of fixed and flexible exchange rates abstract this paper investigates whether japanese output stability since the mid 1970s is attributable to the change in exchange rate regime or to the changing nature of underlying disturbances we decompose foreign and domestic influences on output movements using restrictions on the long run dynamics to identify the disturbances we find that the flexible exchange rate regime is more effective in insulating the economy from foreign disturbances than is the fixed rate regime however in the case of japan it is primarily the changing nature of the fundamental disturbances to the economy that is responsible for greater output stability since the mid 1970s

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

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

crude oil and the macroeconomy tests of some popular notions a note perhaps no other economic events in the post world war ii era have generated as much attention as the series of crude oil price shocks that have jolted the world economy since the opec boycott of 1973 a tremendous amount of space in the popular and professional literature has been devoted to analyzing the impacts of these shocks on the developed economies and the adjustments these shocks have induced one residual of this literature has been a general impression that since 1973 the functional relationship between crude oil prices and the developed macroeconomies has been dramatically and fundamentally altered yet to our knowledge no one has formally tested this impression recent evidence of hamilton 1983 suggests that crude oil prices had a strong impact on the u s business cycle well before 1973 further while textbook treatments of oil price shocks tend to highlight cost push inflationary effects the research of berndt and wood 1975 1979 and wilcox 1983 indicates the net complementarity between energy and capital in the u s economy is quite strong both before and after 1973 thus oil price shocks may have stronger real effects than generally believed in this paper we formally test three popular notions associated with the so called

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

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

commitment risk and consumption do birds of a feather have bigger nests abstract consumption commitments goods like housing for which adjustment is costly change the relationship between risk and consumption commitment provides a motive to reduce consumption when possible future losses are too small to warrant adjustment but not when losses are large enough that adjustment would be worthwhile this implies conditions under which mean preserving increases in risk can increase housing consumption our empirical evidence exploits the interaction of these conditions with a novel proxy for unemployment risk couples sharing an occupation consistent with our model same occupation couples consume more housing only when adjustment costs are high and potential losses are sufficiently large

the linkage between oil price shocks and economic growth with inflation in the presence of technological advances a cge model abstract this study examines whether oil price shocks are inflationary in the us we increase the price of oil in the year 2000 in a manner consistent with the oil price shock of 1973 74 and let the economy experience a hicksian technological change then using a dynamic computable general equilibrium cge model we conduct our analyses under two separate cases 1 regular economic growth and 2 low economic growth we also run three technological scenarios 1 no technology change 2 technological advances in the manufacturing and refining sectors and 3 technological advances in the manufacturing refining chemical and service sectors the effects of these changes are analyzed over the next 20 years until the year 2020 our results suggest that while a shock of the magnitude experienced in the 1970s will have a fairly severe effect on such things as gasoline and refinery prices the aggregate price changes will be largely dissipated over time at the aggregate level furthermore the aggregate level of prices cpi and ppi will fall over time as the level of technological advances rise under both growth scenarios there are several reasons why we would obtain such results first of all the structure of the us economy has changed remarkably since the early 1970s rather than being a manufacturing based economy the us is largely a service based economy today and hence it is more protected form raw materials shortages second the economy has had a steady history of strong growth and the faster an economy grows the quicker disruptions to that economy are dissipated finally our economy is experiencing rapid technological advances in information systems which have served to reduce costs and maintain output in a wide number of economic sectors

imperfect insurance and differing propensities to consume across households abstract this paper extends previous tests of consumption insurance by splitting the sample to examine whether the marginal propensity to consume mpc out of idiosyncratic income shocks is larger for low wealth households than it is for high wealth households using data from the psid i find 1 the mpc of low wealth households is higher than that of high wealth households there are indications that both precautionary savings behavior and liquidity constraints contribute to this difference 2 splitting the data using two different measures of wealth indicates that households perceive housing equity as illiquid 3 when low wealth households are split into two subgroups the mpc of the very low wealth group is smaller reflecting the insurance aspects of means tested safety net programs

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

intertemporal nonseparability or borrowing restrictions a disaggregate analysis using a u s consumption panel we propose a method to test for liquidity constraints which relies on using the within period marginal rate of substitution condition as a benchmark to evaluate the intertemporal euler equation if spot markets for nondurable goods exist but financial markets either do not exist or are imperfect we show how the comparison of first order conditions involving the relevant spot and intertemporal prices can be used to detect the imperfection we apply our methodology to a large sample of u s households drawn from twelve years of the consumer expenditure survey allowing for a general nonseparable preference structure our estimates of first order conditions do not indicate the presence of liquidity constraints with the possible exception of young households

asymmetries in the response of economic activity to oil price increases and decreases abstract it has been common to assume that the relationship between economic activity and oil prices is asymmetric theoretical underpinnings for this asymmetry include costly sectoral reallocation partial equilibrium models of irreversible investment and some version of precautionary savings yet recent studies that use new methodologies to test for asymmetries in u s data have cast some doubts on that premise in this paper we use state of the art techniques to evaluate the presence of asymmetries for a set of oecd countries containing both oil exporters and oil importers we find very little support for the hypothesis that the response of industrial production to oil price increases and decreases is asymmetric our results have important implications for theoretical models of the transmission of oil price shocks they point towards the importance of direct supply and direct demand transmission channels as well as indirect transmission channels that imply a symmetric response

partial insurance and investments in children this article studies the impact of permanent and transitory shocks to income on parental investments in children we use panel data on family income and an index of investments in children from the children of the national longitudinal survey of youth we find that there is partial insurance of parental investments against permanent income shocks but the magnitude of the estimated responses is small we cannot reject the hypothesis of full insurance against temporary shocks another interpretation of our findings is that insurance possibilities are limited but the fact that skill is a non separable function of parental investments over time results in small reactions of these investments to income shocks especially at later ages

the effects of lottery prizes on winners and their neighbors evidence from the dutch postcode lottery each week the dutch postcode lottery pcl randomly selects a postal code and distributes cash and a new bmw to lottery participants in that code we study the effects of these shocks on lottery winners and their neighbors consistent with the life cycle hypothesis the effects on winners consumption are largely confined to cars and other durables consistent with the theory of in kind transfers the vast majority of bmw winners liquidate their bmws we do however detect substantial social effects of lottery winnings pcl nonparticipants who live next door to winners have significantly higher levels of car consumption than other nonparticipants

world business cycles under fixed and flexible exchange rates this paper studies the behavior of monthly industrial production indices during the recent periods of fixed and flexible exchange rate s the central conclusions are as follows industrial production indices are subject to stochastic trend growth the variances of the monthly growth rates are higher in the flexible exchange rate period than in the fixed exchange rate period and are related to the degree of openness and to national income more open economies tend to experience more variability while richer more diversified economies experience less and output movements have been correlated across countries under both exchange rate regimes and there is evidence of a world business cycle copyright 1988 by ohio state university press

international business cycles world region and country specific factors the paper investigates the common dynamic properties of business cycle fluctuations across countries regions and the world we employ a bayesian dynamic latent factor model to estimate common components in macroeconomic aggregates output consumption and investment in a 60 country sample covering seven regions of the world the results indicate that a common world factor is an important source of volatility for aggregates in most countries providing evidence for a world business cycle we find that region specific factors play only a minor role in explaining fluctuations in economic activity we also document similarities and differences across regions countries and aggregates jel f41 e32 c11 c32

consumption dynamics during recessions when will durable expenditures respond strongly to economic stimulus we build from micro evidence and show that in a heterogeneous agent business cycle model with xed costs of durable adjustment responsiveness is substantially dampened during recessions our model estimates imply that during the great recession durable expenditures were half as responsive to additional stimulus as during the boom in the 1990s this procyclical responsiveness is driven by changes in the distribution of households desired durable holdings over the cycle we directly test our model by estimating this distribution empirically using psid micro data and nd that the distribution in the data moves cyclically as predicted in addition to this micro evidence we also provide support for our model s procyclical responsiveness using aggregate time series data and we show this time series evidence is inconsistent with simpler models featuring smooth adjustment costs

real exchange rate effects of monetary shocks under fixed and flexible exchange rates abstract we analyze how the real exchange rate effects of monetary and real shocks depend on the exchange rate regime within a two country rational expectations model with confusion about money and real shocks the model demonstrates that the real exchange rate effect of unanticipated monetary shocks is negatively related to the variance of the domestically created money supply growth and that the effects of increasing domestic money variance on the real exchange rate are less under a fixed rate regime than under a flexible rate regime

tourism participation and expenditure by spanish households the effects of the economic crisis and unemployment abstract this paper examines household tourism participation decisions and tourism expenditure across the business cycle microdata is used from the spanish household budget survey for the years 2006 2010 facilitating an analysis of the consequences of the economic crisis and unemployment on tourism consumption decisions by households by estimating a heckman model the effects of households socioeconomic determinants on participation and expenditure decisions can be identified taking the year 2008 the beginning of the crisis as a reference the stability of the tourism expenditure model is tested identifying variables whose effects alter in times of crisis one important aspect of the study is how household unemployment affects tourism participation and expenditure decisions the effect of unemployment takes into account whether it is the main breadwinner his or her spouse or another member of the household who is unemployed concentrating on those households whose main breadwinner was employed at the time an analysis is also made of how job insecurity affects tourism consumption decisions from the results the unemployment variables can be seen to have a significant explanatory power suggesting that unemployment information does help to explain the evolution of tourism expenditure across the business cycle

realized volatility transmission between crude oil and equity futures markets a multivariate har approach this paper differs from extant literature because it studies volatility co movements with a multivariate orthogonalized har model a flexible specification for the time series of realized volatility which is able to identify short mid and long term spillover effects we examine volatility transmission mechanisms using high frequency data of the stock index futures on s p 500 nikkei 225 ftse 100 and the futures on the west texas intermediate crude oil during the period from september 2002 to september 2012 considering the full sample the short term volatility of the equity futures contains information about future oil volatility incremental to the information inherent in the time series of oil volatility on the other hand weekly and monthly volatilities do not exhibit a significant spillover effect breaking the whole sample into three subsamples no significant granger causalities are observed in the pre crisis period while in the crisis time and its aftermath we document that the us and uk equity market volatilities to granger cause the oil futures volatility which itself leads the japanese market in terms of magnitude we observe an increase in the short term volatility spillover over time studying the residuals of the har transmission models within a ccc dcc garch framework reveals increasing instantaneous correlation between the energy and equity volatilities in the course of time

oil price shocks and stock markets in the u s and 13 european countries abstract oil price shocks have a statistically significant impact on real stock returns contemporaneously and or within the following month in the u s and 13 european countries over 1986 1 2005 12 norway as an oil exporter shows a statistically significantly positive response of real stock returns to an oil price increase the median result from variance decomposition analysis is that oil price shocks account for a statistically significant 6 of the volatility in real stock returns for many european countries but not for the u s increased volatility of oil prices significantly depresses real stock returns the contribution of oil price shocks to variability in real stock returns in the u s and most other countries is greater than that of interest rate an increase in real oil price is associated with a significant increase in the short term interest rate in the u s and eight out of 13 european countries within one or two months counter to findings for the u s and for norway there is little evidence of asymmetric effects on real stock returns of positive and negative oil price shocks for oil importing european countries

crisis and consumption smoothing the dramatic impact of the current crisis on performance of businesses across sectors and economies has been headlining the business press for the past several months extant reconciliations of these patterns in the popular press rely on ad hoc reasoning using historical data on currency crisis episodes across the world we show that the impact of the crisis on a firm s business is best understood by focusing on the impact of the crisis on the behavior of consumers our analyses show that consumer behavior in a crisis is characterized by consumption smoothing at various levels intertemporal intercategory and intracategory these behavioral adjustments result in significant reallocation of consumption expenditures more importantly the smoothing decisions because of a crisis are distinct and independent of the impact of changes in income and prices that accompany a crisis interestingly there is marked variation in the patterns of consumption smoothing across different types of economies taken together these results have important and interesting implications for managers policy makers and academics

mode locking and international business cycle transmission abstract we investigate international business cycle synchronization business cycles in many countries have a tendency to synchronize with one another in what appears to be a world business cycle yet researchers find that trade and capital linkages are not strong enough for one country to drive business cycles in another country how is this world business cycle formed this study suggests that the world business cycle results from a mode locking phenomenon a nonlinear process by which weak coupling between oscillating systems tends to synchronize oscillations in the systems simulations and econometric analyses are performed to attempt to verify this hypothesis

measuring consumption smoothing in cex data this paper proposes and implements a new method of measuring the degree of consumption smoothing using data from the consumer expenditure survey the structure of this survey is such that estimators previously used in the literature are inconsistent simply because income is measured annually and consumption is measured quarterly we impose an ar 1 structure on the income process to obtain a proxy for quarterly income through a projection on annual income by construction this proxy gives rise to a measurement error which is orthogonal to the proxy itself as opposed to the unobserved regressor leading to a consistent estimator we contrast our estimates with the output of two estimators used in the literature we show that while the flrst ols estimator tends to overstate the degree of risk sharing the second iv estimator grossly understates it

the effects of male and female labor supply on commodity demands we examine the effects of male and female labor supply on household demands and present a simple and robust test for the separability of commodity demands from labor supply using data on individual households from six years of the uk fes we estimate a demand system for seven goods which includes hours and participation dummies as conditioning variables allowance is made for the possible endogeneity of these conditioning labor supply variables we find that separability is rejected furthermore we present evidence that ignoring the effects of labor supply leads to bias in the parameter estimates

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

business cycles and the exchange rate system some international evidence this paper investigates the differences in time series behavior of key economic aggregates under alternative exchange rate systems we use a postwar sample of 49 countries to compare the behavior of output consumption trade flows government consumption spending and real exchange rates under alternative exchange rate systems pegged floating and cooperative systems such as the ems we then examine evidence from two particular episodes involving canada and ireland of changes in the exchange rate system aside from greater variability of real exchange rates under flexible than under pegged nominal exchange rate systems we find little evidence of systematic differences in the behavior of macroeconomic aggregates or international trade flows under alternative exchange rate systems these results are of interest because a large class of theoretical models implies that the nominal exchange rate system has important effects on a number of macroeconomic quantities

exogenous oil supply shocks how big are they and how much do they matter for the u s economy abstract the paper proposes a new measure of exogenous oil supply shocks the timing the magnitude and the sign of this measure may differ greatly from current state of the art estimates it is shown that only a small fraction of the observed oil price increases during oil crisis periods can be attributed to exogenous oil production disruptions exogenous oil supply shocks cause a sharp drop of u s real gdp growth after five quarters rather than an immediate and sustained reduction in economic growth and a spike in cpi inflation after three quarters overall exogenous oil supply shocks made remarkably little difference for the evolution of the u s economy since the 1970s although they did matter for some historical episodes

consumption responses to a large shock to financial wealth evidence from italy we estimate marginal propensities to consume from wealth shocks for italian households early in the great recession large asset price shocks in 2007 2008 underpin instrumental variables a euro fall in risky financial wealth resulted in cuts in annual total non durable consumption of 8 5 9 5 5 5 7 cents we find small effects on food spending counterfactuals indicate financial wealth effects were relatively important for consumption falls in italy in 2007 08 the estimated effects are consistent with a simulated lifecycle model that captures the wealth shock also consistent with the model are findings of stronger wealth effects for agents who were pessimistic about stock returns

risk sharing in private information models with asset accumulation explaining the excess smoothness of consumption we study testable implications for the dynamics of consumption and income of models in which first best allocations are not achieved because of a moral hazard problem with hidden saving we show that in this environment agents typically achieve more insurance than that obtained under self insurance with a single asset consumption allocations exhibit excess smoothness as found and defined by campbell and deaton 1989 we argue that excess smoothness in this context is equivalent to a violation of the intertemporal budget constraint considered in a bewley economy with a single asset we also show parameterizations of our model in which we can obtain a closed form solution for the efficient insurance contract and where the excess smoothness parameter has a structural interpretation in terms of the severity of the moral hazard problem we present tests of excess smoothness applied to u k microdata and constructed using techniques proposed by hansen roberds and sargent 1991 to test the intertemporal budget constraint our theoretical model leads us to interpret them as tests of the market structure faced by economic agents we also construct a test based on the dynamics of the cross sectional variances of consumption and income that is in a precise sense complementary to that based on hansen roberds and sargent 1991 and that allows us to estimate the same structural parameter the results we report are consistent with the implications of the model and are internally coherent

social insurance and consumption an empirical inquiry the main stated purposes of social insurance programs have been the maintenance of consumption by people suffering from misfortunes and the stabilization of employment despite this most recent research on unemployment insurance ui and old age insurance has focused on secondary labor market effects with only a few studies looking at stabilization and none considering effects on consumption in this study we examine how ui will affect the consumption of recipients for some individuals ui will help remove the constraints on consumption during periods of reduced income that arise from insufficient savings and imperfect capital markets while for others the ui benefits merely augment the entire lifetime consumption stream the model enables us to estimate what fractions of the population fall into these two categories if individuals are also constrained in the allocation of their reduction consumption consumption propensities out of ui will differ from those out of nonrecipients income the model is tested on aggregate time series data covering 41 consumption categories for 1959 1978 ii and on over 14 000 individuals from the 1972 73 consumer expenditure survey in both data sets we find no more than half of ui benefits are consumed as if the recipients consumption were constrained during times of unemployment in both samples spending out of ui benefits is disproportionately on luxuries though ui recipients spend greater shares of their income on necessities the results imply that a large part of social insurance payments does not go to prevent serious imbalances in individuals lifetime consumption profiles this abstract was borrowed from another version of this item

energy capital substitution wage flexibility and aggregate output supply abstract this paper analyzes the relationship between factor substitution labor market conditions and aggregate output supply in order to study the transmission mechanism of energy price change to the rest of the economy it shows that the energy capital complementarity vs substitutability issue may turn out to be crucial in shaping the direction of the adjustment of aggregate output supply following energy price changes how crucial it is it is shown to depend on the beliefs of firms regarding the stock of capital on the degree to which labor markets clear and on the wage elasticity of labor supply some empirical evidence is presented about the relationship between energy price changes and output supply

intertemporal consumption and credit constraints does total expenditure respond to an exogenous shock to credit there is continuing controversy over the importance of credit constraints this paper investigates whether total household expenditure and debt is affected by an exogenous increase in access to credit provided by a credit market reform that enabled danish house owners to use housing equity as collateral for consumption loans we find that the magnitude of the response is correlated with the amount of equity released by the reform and that the effect is strongest for younger households even for this group the response was moderate the aggregate effect of the reform was significant but small

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

supply contraction and trading protocol an examination of recent changes in the u s treasury market we investigate liquidity and trader behavior in the u s treasury market during recent supply contractions as in the precontraction period dealers employ expandable order strategies to achieve greater than posted depth at the posted price and use expandable orders more often when expected information asymmetry is greater overall however dealers are less likely to discover greater than quoted depth during the supply contraction regimes we find that even after substantial losses in their market share of coupon treasury trading brokers reporting voice brokered trading through govpx provide an important protocol for depth discovery we investigate liquidity and trader behavior in the u s treasury market during recent supply contractions as in the precontraction period dealers employ expandable order strategies to achieve greater than posted depth at the posted price and use expandable orders more often when expected information asymmetry is greater overall however dealers are less likely to discover greater than quoted depth during the supply contraction regimes we find that even after substantial losses in their market share of coupon treasury trading brokers reporting voice brokered trading through govpx provide an important protocol for depth discovery

job loss credit constraints and consumption growth we use direct evidence on credit constraints to study their importance for household consumption growth and for welfare we distentangle the direct effect on consumption growth of a currently binding credit constraint from the indirect effect of a potentially binding credit constraint which generates consumption risk our data is focused on job losers we find that less than 5 of job losers experience a binding credit constraint but for those that do they experience significant welfare losses and consumption growth is 24 higher than for the rest of the population however even among those who are currently unconstrained and who are able to borrow if needed consumption responds to transitory income

new evidence on excess sensitivity of household consumption the monthly salaries and allowances of korean government employees are known in advance but vary greatly throughout the year using a korean monthly panel data set the present study examines how nondurable consumption expenditures in households headed by government employees respond to predictable income changes the study finds a moderate excess sensitivity in consumption that can be attributed to about 9 of the households further analysis shows that these 9 of the households have lower committed expenditures and are likely inattentive consumers

shocks stocks and socks smoothing consumption over a temporary income loss we investigate how households in temporarily straitened circumstances due to an unemploy ment spell cut back on expenditures and how they spend marginal dollars of unemployment insurance ui benefit our theoretical and empirical analyses emphasize the importance of allowing for the fact that households buy durable as well as non durable goods the theoretical analysis shows that in the short run households can cut back significantly on total expenditures without a significant fall in welfare if they concentrate their budget reductions on durables we then present an empirical analysis based on a canadian survey of workers who experienced a job separation exploiting changes in the unemployment insurance system over our sample period we show that cuts in ui benefits lead to reductions in total expenditure with a stronger impact on clothing than on food expenditures our empirical strategy allows that these expenditures may be non separable from employment status the effects we find are particularly strong for households with no liquid assets before the spell started these qualitative findings are in precise agreement with the theoretical predictions jel d11 d12 d91 j65 2009 by the european economic association

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

chinese trade price and yuan s valuation this paper studies how the major economic events would have affected chinese yuan s nominal exchange rate against us dollar from 1989 to 2013 the traditional average treatment effect estimation methods cannot be used to consistently estimate yuan s pegged exchange rate we develop a new estimation strategy by combining a novel panel data method proposed by hisao ching and wan and the purchasing power parity theory based on this new estimation strategy we find that during the period of pegging to us dollar chinese yuan were undervalued before the 1997 asian financial crisis the pegged exchange rate regime starting from january 1994 made the yuan undervalued by 2 62 china s accession to wto caused yuan undervalued by 36 60 after the reform of chinese exchange rate policy in july 2005 the undervaluation of the yuan was reduced to only 0 76 yuan was undervalued again by 20 43 because of 2008 china s economy stimulus package the policy reform in june 2010 made yuan overvalued by 14 40 we conclude that chinese fixed exchange rate policy indeed undervalued the yuan especially after its accession to wto the recent reforms of chinese exchange rate policy made progresses in re evaluating the yuan

oil and the macroeconomy when prices go up and down an extension of hamilton s results in an important paper hamilton 1983 demonstrated a strong correlation between oil price changes and gross national product growth in u s data however his study pertained to a period in which all the large oil price movements were upward and thus it left unanswered the question whether the correlation persists in periods of price decline moreover the price variable he used was somewhat distorted by price controls in the 1970s this note investigates whether hamilton s results continue to hold when the sample is extended to include the recent oil market collapse and the oil price variable is corrected for the effects of price controls particular attention is given to the possibility of asymmetric responses to oil price increases and decreases as suggested in the structural employment literature loungani 1986 davis 1987 hamilton 1988 like hamilton i based my investigation on the gnp equation in sims s 1 980b six variable quarterly vector autoregressive model
