monetary policy and uncertainty in an empirical small open economy model this paper explores optimal policy design in an estimated model of three small open economies australia canada and new zealand within a class of generalized taylor rules we show that to stabilize a weighted objective of output consumer price in ation and nominal interest variation optimal policy does not respond to the nominal exchange this is despite the presence of local currency pricing and due in large part to observed exchange rate disconnect in these economies optimal policies that account for the uncertainty of model estimates as captured by the parameters posterior distrbution similarly exhibit a lack of exchange rate response in contrast to brainard 1967 the presence of parameter uncertainty can lead to more or less aggressive policy responses depending on the model at hand

irving fisher on the international transmission of booms and depressions through monetary standards the role of monetary standards in the international transmission of economic fluctuations particularly the role of the gold standard in the depression has attracted considerable recent attention for instance from choudhri and kochin 1980 hamilton 1988 temin 1989 1993 eichengreen 1992 and bernanke 1995 however this literature has overlooked a pioneering precursor irving fisher are booms and depressions transmitted internationally through monetary standards 1935 which has also been neglected in the literature on fisher i examine fisher s contribution in the context of later research on the topic and explore the place of fisher 1935 in fisher s work

budget constraints and time series evidence on consumption is consumption more or less variable than predicted by the permanent income hypothesis pih to answer that question i develop a procedure based on a long run restriction implied by the consumer s intertemporal budget constraint in contrast to previous work the approach here i does not require any assumptions on the stochastic properties of labor income ii does not impose restrictions on the consumer s information set and iii is robust to departures from the pih model the application of the procedure to postwar u s data suggests that consumption is smoother than the pih model predicts jel 131

wages and human capital in the u s financial industry 1909 2006 we study the allocation and compensation of human capital in the u s finance industry over the past century across time space and subsectors we find that financial deregulation is associated with skill intensity job complexity and high wages for finance employees all three measures are high before 1935 and after 1980 but not in the interim period workers in the finance industry earn the same education adjusted wages as other workers until 1990 and significantly more afterward by 2006 the premium is 40 on average and 200 for top earners and ceos earnings risk and firm size effects account for some of the premium but the majority does not appear to be sustainable

deflation and depression is there an empirical link are deflation and depression empirically linked no concludes a broad historical study of inflation and real output growth rates deflation and depression do seem to have been linked during the 1930s but in the rest of the data for 17 countries and more than 100 years there is virtually no evidence of such a link

the estimation of surprise models and the surprise consumption function in the first part of the paper we outline a method for estimating a class of models in which news or surprises appear and expectations are formed rationally the method is an extension of the errors in variables method of mccallum and wickens as a by product some of pagan s results on the circumstances under which the commonly used two step method of estimating surprise models is efficient are shown to be a consequence of well known theorems on the efficiency of sub system estimation when a subset of equations are exactly identified in the second part of the paper the method is applied to hall s random walk model of consumption which is extended to allow for stochastic interest rates and for leisure and government spending to be substitutes for private spending the extended formulation is a great deal more successful at capturing the salient features of the data we also derive approximate restrictions across the parameters of the model due to the rational expectations hypothesis but find that they are marginally rejected by the data finally we evaluate the ability of the life cycle with rational expectations model to encompass alternative models

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

aggregate employment real business cycles and superior information abstract we test whether dynamic stochastic general equilibrium artificial economies associated with several labor market structures provide an adequate characterization of aggregate employment volatility and dynamics our test is robust to possible misspecifications about the information set used by economic agents to forecast future events accounting for agents superior information we find that the divisible labor indivisible labor labor adjustment costs and labor hoarding structures replicate employment volatility in contrast to the nominal wage contracts structure also the labor hoarding structure provides a substantially better account of employment dynamics

the effect of precautionary saving on consumption in sweden uncertainty concerning future income lowers consumption this is often called the precautionary demand for savings in this paper the existence of precautionary savings in this paper the existence of precautionary saving is investigated using swedish data for the years 1973 1992 as there are no variables for consumers uncertainty a proxy is used assuming an underlying distribution of attitudinal data a variance series is derived including the proxy in different specifications of the consumption function indication of precautionary saving can be found as a result no uncertainty would raise consumption by 4 9

is consumption too smooth long memory and the deaton paradox under common arima representations of income the permanent income hypothesis predicts that the volatility of consumption should be larger than the volatility of unanticipated shocks to income this prediction is not supported by the data the authors examine whether this apparent excess smoothness of consumption is the result of the arima representation s implicit restrictions on low frequency dynamics by using a generalized long memory stochastic representation the authors construct confidence intervals for the long run impulse response of income in the absence of such low frequency restrictions these intervals are quite wide and include regions in which excess smoothness vanishes copyright 1991 by mit press

packaging liquidity blind auctions and transaction efficiencies the costs of implementing investment strategies represent a significant drag on the per formance of mutual funds and other institutional investors it is the responsibility of in stitutional investors and in the interests of the individual investors they represent to seek market mechanisms that mitigate trading costs we investigate an example of one such liquidity provision mechanism whereby liquidity demanders auction a set of trades as a package directly to potential liquidity providers a critical feature of the auction is that the identities of the securities in the package are not revealed to the bidder we demon strate that this mechanism provides a transactions cost savings relative to more traditional trading mechanisms for the liquidity demander as well as an efficient way for liquidity suppliers to obtain order flow we argue that the cost savings afforded this new mechanism are due to the potential for low cost crosses with the bidder s existing inventory positions and through the longer trading horizon and superior trading ability of the bidders this research suggests that the ability to innovate via new liquidity provision mechanisms can provide market participants with transaction cost savings that cannot be easily duplicated on more traditional exchanges

permanent and transitory movements in labor income an explanation for excess smoothness in consumption many have argued that if labor income is difference stationary the permanent income hypothesis predicts that consumption should be relatively volatile in u s aggregate data labor income is well characterized as having a unit root however consumption turns out to be relatively smooth this anomaly is known as deaton s paradox i resolve deaton s paradox by providing decompositions of labor income into permanent and transitory components these preserve the univariate dynamic properties of labor income however when agents distinguish permanent and transitory movements in their labor income as the rational expectations hypothesis asserts they should the permanent income hypothesis correctly predicts the observed smoothness in consumption

international evidence on sticky consumption growth abstract this paper estimates the degree of stickiness in aggregate consumption growth sometimes interpreted as reflecting consumption habits for thirteen advanced economies we find that after controlling for measurement error consumption growth has a high degree of autocorrelation with a stickiness parameter of about 0 7 on average across countries the sticky consumption growth model outperforms the random walk model of hall 1978 and typically fits the data better than the popular mankiw 1989 model though in a few countries the sticky consumption growth and campbell mankiw models work about equally well

a new approach to decomposition of economic time series into permanent and transitory components with particular attention to measurement of the business cycle abstract this paper introduces a general procedure for decomposition of non stationary time series into a permanent and transitory component allowing both components to be stochastic the permanent component is shown to be a random walk with drift and the transitory or cyclical component is a stationary process with mean zero the decomposition methodology which depends only on past data and therefore is computable in real time is applied to the problem of measuring and dating business cycles in the portwar u s economy we find that measured expansions and contractions are of roughly equivalent duration and that our dating of cyclical episodes tends to lead the traditional nber dating and to a lesser extent the growth cycle chronology of zarnowitz and boschan 1977

long memory in foreign exchange rates using the geweke porter hudak test we find evidence of long memory in exchange rate data this implies that the empirical evidence of unit roots in exchange rates may not be robust to long memory alternatives fractionally integrated autoregressive moving average arfima models are estimated by both the time domain exact maximum likelihood ml method and the frequency domain approximate ml method impulse response functions and forecasts based on these estimated arfima models are evaluated to gain insight into the long memory characteristics of exchange rates some tentative explanations of the long memory found in the exchange rates are discussed

finite horizons life cycle savings and time series evidence on consumption abstract this paper develops an explicitly aggregated life cycle model which allows for finite horizons and declining individual labor supply the model can generate a common upward trend in aggregate consumption labor income and nonhuman wealth without relinquishing hall s random walk at the micro level life cycle factors are shown to imply that consumption changes should be a predictable and b smoother than in the infinite horizon model econometric evidence using postwar u s data suggests that neither consumption s predictability nor its excess smoothness can be fully accounted for by life cycle considerations

limited information estimation and evaluation of dsge models we advance the proposition that dynamic stochastic general equilibrium dsge models should not only be estimated and evaluated with full information methods these require that the complete system of equations be specified properly some limited information analysis which focuses upon specific equations is therefore likely to be a useful complement to full system analysis two major problems occur when implementing limited information methods these are the presence of forward looking expectations in the system as well as unobservable non stationary variables we present methods for dealing with both of these difficulties and illustrate the interaction between full and limited information methods using a well known model copyright 2009 john wiley sons ltd

multiple bgps in a growth model with habit persistence this paper establishes multiple balanced growth paths in an otherwise standard competitive growth model without externality or distortions and with households preference dependent upon how his her consumption compares to a habit stock formed by his her own past consumption the key feature in our model is that consumption forms habits in combination with existing habits this model establishes multiple equilibria because habit persistence induces an internal intertemporal complementarity effect among consumption flows with current consumption reinforcing future consumption as a result there exist two balanced growth paths with one path exhibiting low consumption and habits and high economic growth and the other path exhibiting high consumption and habits and low growth that is not necessarily a development trap both steady states are saddles but global indeterminacy arises where a high balanced growth path co exists with a low balanced growth path where the two equilibrium paths cannot be pareto ranked and history need not matter for the selection of the equilibrium path

multicointegration in us consumption data the present study tests for the existence of multicointegration between real per capita private consumption expenditure and real per capita disposable personal income in the usa in doing so the study exploits the fact that the flows of disposable income and consumption expenditure on the one hand and the stock of consumers wealth which can be considered as cumulative past discrepancies between the flows of income and expenditure on the other hand can be thought of as a stock flow model in which multicointegration is likely to occur recently developed i 2 techniques are applied for testing for multicointegrating relations and find supporting evidence for the existence of multicointegration in us consumption data

saving and income smoothing evidence from panel data abstract in this paper we use data from a panel of dutch households to investigate the behavior of savings as in campbell 1987 we examine whether the pattern of savings is consistent with the predictions of the rational expectations permanent income model we consider one important prediction of the model whether savings anticipate future income changes we test the predictions of the permanent income model in several ways first we propose some informal tests that exploit directly the information on expected future income changes available in the data we then perform a test of the model by setting up a vector autoregression var in terms of savings and income changes and by using euler equations expressed in terms of savings the empirical evidence shows that in all the specifications used in this paper the permanent income model is rejected contrary to the evidence from u s macro data we do not find that the excess sensitivity of consumption to income is responsible for the rejection of the model

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

does buffer stock saving explain the smoothness and excess sensitivity of consumption one of the lasting contributions to modernday consumer theory is the idea that consumption is determined by the expected value of lifetime resources or permanent income the modern day specification of this concept is typically presented as a special case of intertemporalchoice theory where felicity functions are quadratic labor income is stochastic there are no restrictions on borrowing consumers have infinite horizons and expectations are formed rationally we refer to this model as the permanentincome hypothesis pih although the pih has considerable intuitive appeal a series of influential papers published after its inception revealed two notable discrepancies between the model s predictions and aggregate data first the model predicts that consumption growth should be more volatile than income growth if aggregate income growth has positive serial correlation as the quarterly data suggest it does yet aggregate consumption growth is in fact much smoother than aggregate income growth angus deaton 1987 john y campbell and deaton 1989 jordi gali 1991 second the pih predicts that consumption changes should be orthogonal to predictable or lagged income changes yet the coffelation between consumption growth and lagged income growth has been found to be one of the most robust features of aggregate data for example marjorie a flavin 1981 alan s blinder and deaton 1985 campbell and n gregory mankiw 1989 orazio p attanasio and guglielmo weber 1993 thus aggregate consumption growth has been described as exhibiting two puzzles it is both excessively smooth relative to current labor income growth and excessively sensitive to lagged labor income growth 2 in response to these and other empirical anomalies researchers have recently sought out modifications of the pih framework chief ludvigson federal reserve bank of new york 33 liberty street new york ny 10045 michaelides university of cyprus p o box 20537 1678 nicosia cyprus a previous version of this paper appeared under the title can we explain the consumption excesses yet aggregate consumption implications of buffer stock saving behavior for many helpful comments we thank orazio attanasio dave backus ben bernanke john y campbell christopher carroll todd clark angus deaton pierreolivier gourinchas bo honore james kahn martin lettau costas meghir christina paxson steve pischke andrew samwick christopher sims mark watson guglielmo weber michael woodford steve zeldes and two anonymous referees conference participants at the national bureau of economic research summer workshop on the aggregate implications of microeconomic consumption behavior july 1998 the tmr workshop on saving and pensions center tilburg university march 1999 and the new york area macroeconomics workshop october 1998 seminar participants at columbia university insead the new york federal reserve university college london london business school city university business school university of cyprus tel aviv university and jeffrey brown for excellent research assistance the views expressed are those of the authors and do not necessarily reflect those of the federal reserve bank of new york or the federal reserve system any errors or omissions are the responsibility of the authors 1 note that the important insight of danny quah 1990 that individuals may be better able than econometricians to distinguish short run from long run innovations to their income cannot resolve the excess smoothness puzzle laid out in campbell and deaton 1989 these authors show that in the context of the pih excess sensitivity and excess smoothness are the same phenomena in addition campbell 1987 demonstrates that superior information of the type emphasized by quah will show up in households saving behavior and using this information allows the econometrician to control for the agent s private information when predicting income since excess sensitivity is well established and controlling for saving does not eliminate it see campbell and deaton 1989 the observed smoothness of consumption cannot be explained by superior information on the part of permanent income consumers see deaton 1992 for further discussion 2 philippe bacchetta and stefan gerlach 1997 and ludvigson 1999 document another kind of excess sensitivity the correlation between consumption growth and predictable changes in consumer credit although we do not explore these findings here ludvigson finds that a bufferstock model with time varying liquidity constraints can replicate such a correlation

permanent income in general equilibrium abstract this paper reviews recent tests of the permanent income hypothesis this literature suggests that consumption is too sensitive to current income relative to the predictions of the usual partial equilibrium model it is then argued that in general equilibrium attempts to move along a consumption possibilities frontier exhibiting diminishing returns would naturally give rise to endogenous changes in interest rates creating a link between consumption and current income a fully specified general equilibrium example is introduced which does indeed exhibit the same excess sensitivity reported in the literature for precisely this reason

why is consumption so smooth for thirty years it has been accepted that consumption is smooth because permanent income is smoother than measured income this paper considers the evidence for the contrary position that permanent income is in fact less smooth than measured income so that the smoothness of consumption cannot be straightforwardly explained by permanent income theory the paper argues that in postwar u s quarterly data consumption is smooth because it responds with a lag to changes in income

limited disclosure and hidden orders in asset markets abstract opacity assumes at least two prominent forms in asset markets dark exchanges and over the counter markets enable expert investors to hide their orders while originators carefully control the disclosure of fundamental information about the assets they source we describe a simple model in which both forms of opacity hidden orders and limited disclosure complement one another costly investor expertise gives originators incentives to deliver assets of good quality keeping expert orders hidden generates the rents investors need to justify investing in expertise in the first place limiting disclosure mitigates the resulting adverse selection issues originators prefer to restrict the information they can convey to experts because it encourages the participation of non experts this optimal organization of asset markets can be decentralized using standard financial arrangements

fractional monetary dynamics we test for fractional dynamics in us monetary series their various formulations and components and velocity series using the spectral regression method we find evidence of a fractional exponent in the differencing process of the monetary series both simple sum and divisia indices in their components with the exception of demand deposits savings deposits overnight repurchase agreements and term repurchase agreements and the monetary base and money multipliers no evidence of fractional behaviour is found in the velocity series granger s journal of econometrics 25 1980 aggregation hypothesis is evaluated and implications of the presence of fractional monetary dynamics are drawn

limited liability contracts between principal and agent abstract the optimal strategy of the principal is examined in an environment where there are ex post limitations on the maximum penalty that can be imposed on a riskneutral agent contrary to the case in which such limitations are not imposed it is in the principal s interest to deliberately forego the opportunity to induce socially efficient behavior and to instead design a contract that induces the agent to realize an efficient outcome only in the most productive state of nature and perhaps in certain very unproductive states the properties of the contract are examined in detail

nominal wage stickiness and aggregate supply in the great depression building on earlier work by eichengreen and sachs we use data for 22 countries to study the role of wage stickiness in propagating the great depression recent research suggests that monetary shocks transmitted internationally by the gold standard were a major cause of the depression accordingly we use money supplies and other aggregate demand shifters as instruments to identify aggregate supply relationships we find that nominal wages adjusted quite slowly to falling prices and that the resulting increases in real wages depressed output these findings leave open the question of why wages were so inertial in the face of extreme labor market conditions

a silver lifeboat not silver fetters why and how the silver standard insulated china from the 1929 great depression summary we use counterfactual simulations based on an estimated dynamic stochastic general equilibrium model to demonstrate why china was affected less than other major countries during the first two years of the great depression we show that being on a silver standard insulated china from the adverse consequences of the great depression by saving the country both from a tightening of monetary conditions and from a detrimental internal deflation without the insulation of the silver standard china might have suffered from a cumulative output loss of between 11 and 23 and its inflation might have become deflation copyright 2015 john wiley sons ltd

long memory in us disaggregated petroleum consumption evidence from univariate and multivariate lm tests for fractional integration previous studies that have tested for a unit root in aggregate energy consumption have potentially reached misleading conclusions because they fail to allow for the possibility that energy consumption might be fractionally integrated and do not distinguish between different types of energy consumption this study tests for long memory in disaggregated petroleum consumption in the united states using univariate and multivariate lagrange multiplier lm tests for fractional integration the results point strongly to the need to distinguish between different forms of energy consumption and allow for a generalization of the i 0 i 1 dichotomy when considering the order of integration of energy consumption allowing for short run dynamics the univariate test suggests that less than 50 of the series are fractionally integrated consistent with expectations the non stationary series are found to have the highest mean and standard deviation the multivariate test suggests that petroleum consumption in the commercial and industrial sectors is clearly fractionally integrated when allowing for short run dynamics and as such exhibits persistent effects while petroleum consumption in the residential sector is a stationary process

consumption innovation persistence and the excess smoothness debate based on studies using us data consumption is too smooth relative to the implications of the rational expectations permanent income hypothesis repih of consumption we examine this and a number of related methodologicalissues for the uk using maximum likelihood estimation mle of an autoregressive fractionally integrated moving average arfima model of the income process we conclude that an innovation to income has a persistent effect on consumption and that in contrast to the findings from us studies consumption is too volatile compared to the repih model further mle is substantially more efficient than the semi parametric method of estimating arfima models which has previously been used in this area

consumption puzzles and precautionary savings abstract when marginal utility is convex agents accumulate savings as a precautionary measure against labor income eventualities this paper shows that precautionary savings can go a long way in making the excess growth excess smoothness and excess sensitivity features of consumption consistent with the stochastic processes of labor income observed in the u s at the microeconomic level

current account dynamics under information rigidity and imperfect capital mobility abstract the current account in developed countries is highly persistent and volatile in comparison to their output growth the standard intertemporal current account model with rational expectations re fails to explain the observed current account and consumption dynamics the re model extended with imperfect capital mobility by shibata and shintani 1998 can account for the consumption dynamics but only at the cost of the explanatory power for the volatility of the current account this paper replaces re in the intertemporal current account model with sticky information si in which consumers are inattentive to shocks to their income the si model can better explain a persistent and volatile current account than the re model but it overpredicts the persistence of changes in consumption the si model extended with imperfect capital mobility explains both the current account and consumption provided that sufficiently high degrees of information rigidity and imperfect capital mobility are considered

asset markets with heterogeneous information this paper studies competitive equilibria of economies where assets are heterogeneous and traders have heterogeneous information about them markets are defined by a price and a procedure for clearing trades and any asset can in principle be traded in any market buyers can use their information to impose acceptance rules which specify which assets they are willing to trade in each market the set of markets where trade takes place is derived endogenously the model can be applied to find conditions under which these economies feature fire sales contagion and flights to quality

the relationship between oil prices and the nigerian stock market an analysis based on fractional integration and cointegration abstract we examine the relationship between oil prices and the stock market in nigeria we focus on the degree of persistence of the series and based on the similarities observed between the two series a fractionally cointegrated framework is proposed the results indicate that the two series display a similar order of integration which is close to although above 1 testing for cointegration this is decisively rejected since the order of integration in the equilibrium relationship was similar to that of the individual series however testing for long memory with oil prices acting as a weakly exogenous regressor we obtained significant evidence of a positive relationship between the two variables though with a short memory effect this relation being significant only during the following three months

precautionary saving an explanation for excess sensitivity of consumption the permanent income hypothesis under certainty equivalence yields a martingale consumption process empirically this hypothesis is rejected because consumption is excessively sensitive to anticipated income one approach to account for excess sensitivity is to relax certainty equivalence by using utility functions that induce precautionary saving this article analyzes a hyperbolic absolute risk aversion utility function empirically some reasonable parameterizations of this specification allow one to match the excess sensitivity associated with the data these parameterizations also permit one to account for the excess smoothness problem excess sensitivity and excess smoothness however do not reflect the same phenomenon

consumption and portfolio choice under internal multiplicative habit formation this paper explores the optimal consumption and investment behavior of an individual who derives utility from the ratio between his consumption and an endogenous habit we obtain closed form policies under general utility functionals and stochastic investment opportunities by developing a nontrivial linearization to the budget constraint this enables us to explicitly characterize how habit formation affects the marginal propensity to consume and optimal stock bond investments we also show that in a setting that combines habit formation with epstein zin utility consumption no longer grows at unrealistically high rates at high ages and investments in risky assets decrease

testing the permanent income hypothesis the evidence from canadian data this paper investigates whether there are variants of the permanent income model that are consistent with seasonally unadjusted quarterly postwar canadian data the analysis is based on a misspecification test equation which nests the standard permanent income model the results obtained are somewhat unfavourable to the permanent income hypothesis the same results also apply to more general models in which the real interest rate is time varying and the utility function is non separable in consumption and the stock of durable goods un test de l hypothese du revenu permanent resultats derives a partir des donnees cana diennes ce memoire presente les resultats d une enquete pour etablir s il existe un ou des variantes du modele du revenu permanent qui soient compatibles avec les donnees trimestrielles canadiennes non desaisonnalisees pour la periode de l apres seconde guerre mondiale l analyse est fondee sur une equation qui encastre le modele de revenu perma nent standard mais qui est enrichie pour tester la specification de l 6equation les resultats obtenus sont quelque peu defavorables a l hypothese du revenu permanent les memes resultats s appliquent aussi a des modeles plus generaux dans lesquels le taux d interet reel

silver points silver flows and the measure of chinese financial integration abstract to what degree were chinese financial markets integrated with the rest of the world prior to the 1949 revolution and to what extent was the chinese foreign exchange market efficient during this period we estimate silver points for the shanghai market from 1905 to 1933 to answer these questions our inferred measures are small in value favorably match measured costs of the silver trade derived from contemporary accounts and fare well in the comparison to estimates of trans atlantic gold points this leads to the conclusion that the degree of chinese financial market integration was substantial however during and immediately after world war i our estimates of the silver points increased appreciably foreshadowing the collapse of china s linkages to world financial markets beginning in the 1930s

priors from general equilibrium models for vars abstract this paper uses a simple new keynesian dynamic stochastic general equilibrium model as a prior for a vector autoregression shows that the resulting model is competitive with standard benchmarks in terms of forecasting and can be used for policy analysis jel classification c11 c32 c53 key words bayesian analysis dsge models forecasting vector autoregressions 1 introduction dynamic stochastic general equilibrium dsge models are popular nowadays in macroeconomics they are taught in virtually every economics ph d program and represent a predominant share of publications in the field yet when it comes to policy making these models are scarcely used at least from a quantitative point of view the main quantitative workhorse for policy making at the federal reserve system is frb us a macro econometric model built in the cowles foundation tradition a style of macroeconomics that is no longer taught in many ph d programs 1 in their decision process fed policy makers rely heavily on forecasting they want to know the expected path of inflation in the next few quarters and by how much a 50 basis point increase in the federal funds rate would affect that path frb us offers answers to these questions answers that many macroeconomists would regard with suspicion given both the lucas 1976 critique and the fact that in general the restrictions imposed by cowles foundation models are at odds with dynamic general equilibrium macroeconomics sims 1980 general equilibrium models on the other hand have a hard time providing alternative answers the fact that these models are perceived to do badly in terms of forecasting as they are scarcely parameterized is perhaps one of the reasons why they are not at the forefront of policy making while progress is being made in the development of dsge models that deliver acceptable forecasts e g smets and wouters 2003 this paper proposes an approach that combines a stylized general equilibrium model with a vector autoregression var to obtain a specification that both forecasts well and is usable for policy analysis specifically the approach involves using prior information coming from a dsge model in the estimation of a vector autoregression loosely speaking this prior can be thought of as the result of the following exercise i simulate time series data from the dsge model ii fit a var to these data in practice we replace the sample moments of the simulated data by population moments computed from the dsge model solution since the dsge model depends on unknown structural parameters we use a hierarchical prior in our analysis by placing a distribution on the dsge model parameters a tightness parameter controls the weight of the dsge model prior relative to the weight of the actual sample markov chain monte carlo methods are used to generate draws from the joint posterior distribution of the var and dsge model parameters the paper shows that the approach makes even a fairly stylized new keynesian dsge model competitive with standard benchmarks in terms of forecasting real output growth inflation and the nominal interest rate the three variables that are of most interest to policy makers 2 up to this point our procedure borrows from the work of dejong ingram and whiteman 1993 and ingram and whiteman 1994 who are the first to use priors from dsge models for vars ingram and whiteman showed that prior information from the bare bones stochastic growth model of king plosser and rebelo 1988 is helpful in forecasting real economic activity such as output consumption investment and hours worked in addition to documenting the forecasting performance of a trivariate var with a prior derived from a monetary dsge model this paper makes two contributions that significantly extend the earlier work first we show formally how posterior inference for the var parameters can be translated into posterior inference for dsge model parameters

money in an estimated business cycle model of the euro area this article examines the role of money in a small scale dynamic general equilibrium model of the euro zone estimated by maximum likelihood the model allows for both intertemporal and intratemporal non separability in preferences we find first that real balances do not affect the marginal utility of consumption second money demand shocks mainly help to forecast real balances while real shocks explain the bulk of price output and interest rates fluctuations third the calculation of the natural rate of interest reveals that the evolution of the interest rate is mostly accounted for by the real sources of fluctuations

on the fit of new keynesian models this article provides new tools for the evaluation of dynamic stochastic general equilibrium dsge models and applies them to a large scale new keynesian model we approximate the dsge model by a vector autoregression and then systematically relax the implied cross equation restrictions and document how the model fit changes we also compare the dsge model s impulse responses to structural shocks with those obtained after relaxing its restrictions we find that the degree of misspecification in this large scale dsge model is no longer so large as to prevent its use in day to day policy analysis yet is not small enough to be ignored

post deregulation bank deposit rate pricing the multivariate dynamics the relationship between wholesale and retail interest rates since deregulation is of substantial interest to economists and policymakers because the predictability of the monetary aggregates and their relationship to bank reserves depend on adjustment patterns in the wholesale and retail money markets we provide evidence on the nature of wholesale retail interest rate relationships by examining the dynamic interactions among two wholesale interest rates federal funds and six month treasury bills and three retail deposit rates six month consumer certificates of deposit money market deposit accounts and super now s we perform a multivariate time series analysis with particular attention paid to causal patterns and the shapes of impulse response functions a number of stylized facts related to size of adjustment speed of adjustment and pattern of adjustment are established for the response of retail rates to unanticipated shocks in wholesale rates

international evidence on the persistence of economic fluctuations abstract this paper presents new evidence on the persistence of fluctuations in real gnp we estimate two measures of persistence nonparametrically using post war quarterly data from canada france germany italy japan the united kingdom and the united states we compare these estimates with monte carlo results from various ar 2 processes for six out of seven countries the point estimates indicate that a 1 shock to output should change the long run unvariate forecast of output by well over 1 low order arma models yield similar conclusions finally we examine the persistence in relative outputs of different countries

blanchard s model of consumption an empirical study this article derives several empirically testable implications for blanchard s consumption model which has been widely used in analytical macroeconomic research cointegration methods are applied the parameter that measures the life horizon of households is estimated and the consumption model is tested quarterly canadian data are used there is no empirical evidence against the assumption that households behave as if they live forever within blanchard s framework blanchard s model of consumption is strongly rejected by the data however

risk sharing and industrial specialization regional and international evidence the authors provide empirical evidence that risk sharing enhances specialization in production to the best of their knowledge this well established and important theoretical proposition has not been tested before the empirical procedure is summarized as follows first the authors construct a measure of specialization in production and calculate an index of specialization for each of the european community ec and non ec oecd countries u s states canadian provinces japanese prefectures latin american countries and regions of italy spain and the united kingdom then they estimate the degree of capital market integration a measure of risk sharing within each of these groups of regions the ec countries the non ec oecd countries the united states canada japan italy spain and the united kingdom and rely on another author s estimate for latin america finally they perform a regression of the specialization index on the degree of risk sharing controlling for relevant economic variables they find a positive and significant relation between the degree of specialization of individual members of a group of countries provinces states or prefectures and the amount of risk that is shared within the group the authors perform regressions using variables such as shareholder rights and the size of the financial sector relative to gdp as instruments for the amount of inter regional risk sharing these regressions confirm that risk sharing facilitated by a favorable legal environment and a developed financial system is a direct causal determinant of industrial specialization this abstract was borrowed from another version of this item

the deaton paradox in a long memory context with structural breaks this article contributes to the permanent income hypothesis pih and excess consumption smoothness debate in the context of fractional integration we show that the excess consumption smoothness result is a consequence of the quarterly data frequency commonly employed in the empirical work in fact the i 1 hypothesis is rejected for the income process with monthly data in favour of a fractional integration order lower than 1 moreover if a structural break is taken into account we observe a substantial reduction in the degree of consumption smoothness especially after the break found in 1975

is consumption too smooth the case of the united kingdom this study consider whether for the uk the restrictions of the rational expectations permanent income repi model of consumption are consistent with the data and whether consumption is too smooth given innovations in labour income some of the findings confirm those for the usa the repi restrictions are rejected however in marked contrast to the result of campbell and deaton 1989 little is found to support the view that consumption is too smooth indeed there is some support for the view that consumption is too volatile some insight is given as to how such results can arise

testing the stochastic implications of the life cycle permanent income hypothesis using uk regional time series data this paper applies exclusion tests of the pure life cycle permanent income hypothesis lcpih to time series data on each of the eleven standard regions of the uk data are annual and extend from 1975 to 1994 the results obtained suggest that there are considerable differences in consumption behaviour across the regions theory has indicated that a departure of consumption behaviour from that predicted by the lcpih can occur because of a change in unemployment consequently a comparison is undertaken of the empirical results obtained for the eleven regions and the respective unemployment movements following this comparison it is possible to conclude that the contrasting unemployment experiences of the regions of the uk have contributed significantly to yet cannot account for fully the observed differences in consumption behaviour
