test of the adjustment process and linear homogeneity in a stock adjustment model of money demand stock adjustment models of money demand have employed either the nominal or real adjustment process but they have not been tested statistically due to their nonnestedness this paper formulates a general stock adjustment model which includes both nominal and real adjustment processes as its nested subsets each process is then tested against the general specification the paper also examines the homogeneity of money demand with respect to price level and income in the general model

interest rate expectations and interest parity abstract this paper examines an hypothesis for explaining divergences from interest parity that is based on interest rate expectations if interest rates are expected to rise significantly within the arbitrage oppurtunity implies riskless profit waiting in ths way has been noted in the historical literature seems to make sense theoritically if portfolio adjusment cost in the capital market outweigh any costs of being out of long term equilibrium and explains a significant portion of us uk interest parity divergences using onshore assets in a recent floating preiod

instability of the u s money demand function this paper surveys the two major episodes of instability of the u s money demand function known respectively as the mystery of missing money and the great velocity decline it also assesses the recent literature on open economy money demand models and their usefulness in explaining the puzzling behavior of money demand manifested shortly after the transition to floating exchange rates copyright 1991 by blackwell publishers ltd

the long and short of money short run dynamics within a structural model empirical examinations into aggregate money demand functions generally incorporate a monetary aggregate as the dependent variable while this custom may be inefficient it does not create any new difficulties for estimating the demand function s long run parameters as money supply would equal money demand the short run estimates however are not as fortunate as the monetary aggregate is a measure of supply and not demand one needs to tease out the short run responses associated with money demand changes with those which are associated with monetary supply shocks the present article therefore proposes a more complete representation of monetary sector behaviour and in doing so finds significant support for the so called buffer stock money demand models

monetary anticipations and the demand for money reply to mackinnon and milbourne abstract mackinnon and milbourne 1984 in an extended comment on carr and darby 1981 claim that money supply shocks do not enter the money demand function for the united states this reply discusses the economic and econometric errors which led to this conclusion and presents further empirical evidence in support of our approach

estimating money demand functions the question of which functional forms of money demand regression equations are useful for empirical work is addressed here specifically it is argued that a functional form that focuses attention on the ability of the growth rate of nominal money to predict the inflation rate is a useful way of summarizing empirical evidence on the existence of a stable money demand function the results of estimating and simulating this functional form as well as standard functional forms are presented in the final part of this paper a typical equation expressing the public s demand for real money balances m is as follows

measuring the opportunity cost of holding money more evidence on the term structure of interest rates abstract this paper tests the statistical importance and forecasting performance of a term structure money demand equation relative to two competing specifications the evidence indicates that the term structure specification is preferred to one using a long term interest rate but not a short term rate forecasts for 1981 1982 reveal that the term structure model is preferable to both alternatives

money and prices evidence from the g7 countries this paper examines the exogeneity of money and prices within a money demand vector error correction model the exogeneity of the variables is central to several buffer stock models however the paper makes two modifications to the traditional approach the first is to explicitly acknowledge the importance of the supply of money function by including the function alongside its demand counterpart the second is to estimate the behaviour of the nominal sector and real sector simultaneously overall the results from the g7 countries suggest that the concerns raised by buffer stock models are relevant

a probability based stress test of federal reserve assets and income to support the economy the federal reserve amassed a large portfolio of long term bonds we assess the fed s associated interest rate risk including potential losses to its treasury securities holdings and declines in remittances to the treasury unlike past examinations of this interest rate risk we attach probabilities to alternative interest rate scenarios these probabilities are obtained from a dynamic term structure model that respects the zero lower bound on yields the resulting probability based stress test finds that the fed s losses are unlikely to be large and remittances are unlikely to exhibit more than a brief cessation

when does a central bank s balance sheet require fiscal support abstract using a simple general equilibrium model we argue that it would be appropriate for a central bank with a large balance sheet composed of long duration nominal assets to have access to and be willing to ask for support for its balance sheet by the fiscal authority otherwise its ability to control inflation may be at risk this need for balance sheet support a within government transaction is distinct from the need for fiscal backing of inflation policy that arises even in models where the central bank s balance sheet is merged with that of the rest of the government

costly portfolio adjustment and the short run demand for money in many empirical studies the short run demand for money includes a lagged dependent variable this is usually attributed to some cost of adjusting money balances toward their desired level this short run money demand equation is sometimes used as a structural equation in models in which market clearing is also assumed in the sense that money supply equals short run money demand in this paper a theoretical counterexample demonstrates that this use of a short run money demand equation is not generally valid this finding challenges the usual interpretation of the lagged dependent variable

buffer stock money interpreting short run dynamics using long run restrictions time series techniques are used to assess the quantitative importance of buffer stock money the short run response of real money holdings to nominal money supply shocks the empirical model a vector autoregression of real and nominal money balances captures general dynamic properties of the time series but requires theoretical restrictions for sensible interpretation the authors just identify the system by imposing a long run neutrality restriction nominal money shocks have no permanent effects on real money they find that buffer stock effects play an important role in the evolution of real m1 in the short run the evidence for m2 is less conclusive copyright 1994 by ohio state university press

conditional euro area sovereign default risk we propose an empirical framework to assess the likelihood of joint and conditional sovereign default from observed cds prices our model is based on a dynamic skewed t distribution that captures all salient features of the data including skewed and heavy tailed changes in the price of cds protection against sovereign default as well as dynamic volatilities and correlations that ensure that uncertainty and risk dependence can increase in times of stress we apply the framework to euro area sovereign cds spreads during the euro area debt crisis our results reveal significant time variation in distress dependence and spill over effects for sovereign default risk we investigate market perceptions of joint and conditional sovereign risk around announcements of eurosystem asset purchases programs and document a strong impact on joint risk

the impact of industrial policy on japan s trade specialization recent research has demonstrated the possibility of welfare enhancing industrial policy this paper analyzes the impact of industrial policy on japan s trade pattern and explores the possibility that it has been welfare enhancing econometric results indicate that industrial policies have had an impact on japan s trade specialization these results are obtained contemporaneously and when the explanatory variables are lagged suggesting either that policymakers have been forward looking or that policy interventions have had persistent long lasting effects although some cases of successful targeting are uncovered welfare enhancing interventions appear to have been the exception not the rule copyright 1993 by mit press

the mystique surrounding the central bank s balance sheet applied to the european crisis abstract a central bank s resource constraint bounds the dividends it can distribute by the present value of seignorage which is a modest share of gdp this is in spite of the mystique behind a central bank s balance sheet moreover the statutes of the federal reserve or the ecb make it difficult for it to redistribute resources across regions in a simple model of sovereign default where multiple equilibria arise if debt repudiation lowers fiscal surpluses the central bank may help to select one equilibrium the central bank s main lever over fundamentals is to raise inflation but otherwise the balance sheet gives it little leeway

uk competitiveness policy vs japanese industrial policy it is often claimed that japanese industrial policy targeted high growth or high productivity growth sectors see inter alia johnson i982 carliner i986 nester i99i tyson 1992 it is then argued that because both the targeted industries and the japanese economy have prospered it follows that japanese industrial policy must have been successful hence britain and other advanced nations either are justified in emulating or should hasten to follow the japanese example this raises the question of whether the united kingdom s competitiveness policy is the appropriate response or is a completely different animal the purpose of this paper is to explore the main areas in contention but before doing so it is important to be clear about what one means by industrial and competitiveness policies

the mystery of the printing press monetary policy and self fulfilling debt crises we study the mechanism by which unconventional balance sheet monetary policy can rule out self fulfilling sovereign default in a model with optimizing but discretionary fiscal and monetary policymakers by purchasing sovereign debt the central bank e ectively swaps risky government paper for monetary liabilities only exposed to inflation risk thus yielding a lower interest rate we characterize a critical threshold for central bank purchases beyond which absent fundamental fiscal stress the government strictly prefers primary surplus adjustment to default since default may still occur for fundamental reasons however the central bank faces the risk of losses on sovereign debt holdings which may generate ine cient inflation this risk does not undermine the credibility of a backstop nor the ability of a central bank to pursue its inflation objectives when the latter enjoys fiscal backing or fiscal authorities are su ciently averse to inflation

the effects of protection on the factor content of japanese and american foreign trade data on pre tokyo round tariffs and ad valorem approximations of nontariff barriers are used in the michigan computational model of world production and trade to calculate changes in commodity trade attributable to protection in japan and the united states data on factor requirements in production are then used to calculate the factor contents of these computed changes in trade results indicate that japanese protection is more distortionary of factor markets in japan and the united states than is american protection and that u s manufacturing labor would be the least likely to gain from trade liberalization in japan and or the united states copyright 1988 by mit press

an evaluation of factor endowments and protection as determinants of japanese and american foreign trade we consider the relationship between the factor content of japanese and american foreign trade and examine empirically whether discrepancies between the heckscher ohlin theoretical predictions and the observed patterns of trade can be attributed to protection the michigan model of world production and trade is used for computational purposes we find some evidence of discrepancies between predicted and observed trade patterns but removal of protection either worsens these discrepancies or reduces them by only a small amount some possible reasons for the empirical shortcomings of the heckscher ohlin theory are offered in conclusion

a dynamic multivariate heavy tailed model for time varying volatilities and correlations we propose a new class of observation driven time varying parameter models for dynamic volatilities and correlations to handle time series from heavy tailed distributions the model adopts generalized autoregressive score dynamics to obtain a time varying covariance matrix of the multivariate student t distribution the key novelty of our proposed model concerns the weighting of lagged squared innovations for the estimation of future correlations and volatilities when we account for heavy tails of distributions we obtain estimates that are more robust to large innovations we provide an empirical illustration for a panel of daily equity returns

are price equations really money demand equations on their heads it is often argued that the dependent variable in money demand functions is really the price level the money stock itself being exogenous a recent approach which stresses the theme is the buffer stock hypothesis in which money supply shocks explicitly appear in the demand for money function because prices and interest rates do not adjust rapidly enough to bring about short run equilibrium in the money market although this approach has been adopted by a number of authors it is not been subjected to much econometric testing in this paper we outline the economic and econometric issues involved in testing the exogenous money buffer stock hypothesis and subject it to a variety of tests using three different data sets none of our results supports the hypothesis fundamental restrictions are rejected at very high levels of significance and a reasonably good money demand equation is seen to be badly misspecified if interpreted as a price equation this abstract was borrowed from another version of this item

the liquidity effects of official bond market intervention to ensure depth and liquidity the european central bank intervened in sovereign debt markets through its securities markets programme smp providing a unique opportunity to estimate the effects of large scale asset purchases on sovereign bond liquidity premia from reduced form estimates we find robust economically significant impact and lasting reductions in sovereign bonds liquidity premia in response to official purchases we develop a search based asset pricing model to understand our empirical results the theory implies that bond liquidity premia fall in response to both official purchases and rising sovereign default probabilities as seen in the data

disequilibrium buffer stock models a survey abstract this paper surveys the growing literature on buffer stock models of the monetary transmission process the first part indicates the basic issue of how assumed exogenous changes in the money supply work their way through the economic system via disequilibrium in the money market after a brief historical development buffer stock models are divided into four types depending upon whether the disequilibrium arises in stocks and or flows and to whether changes in the money stock are purely exogenous the empirical implications including how buffer stock models explain the recent behaviour of money demand functions are given theoretical and empirical criticisms of the models are presented in terms of the classification system the survey concludes that whilst the buffer stock notion is an interesting idea the current models do not lend themselves to empirical testing and those models which do have performed poorly

welfare enhancing export subsidies this paper shows that export subsidies on marginal goods and those on nonmarginal goods have opposite welfare effects for the country imposing these subsidies where marginal goods are the ones that would be exported by only a small amount or not at all under free trade but whose export can be promoted considerably by export subsidies the former enhances the imposing country s welfare while the latter worsens it the paper also throws light on related issues such as industrial targeting policy

coordination failures and the lender of last resort was bagehot right after all the classical doctrine of the lender of last resort lolr elaborated by bagehot 1873 asserts that the central bank should lend to illiquid but solvent banks under certain conditions several authors have argued that this view is now obsolete in modern interbank markets a solvent bank cannot be illiquid this paper provides a possible theoretical foundation for rescuing bagehot s view our theory does not rely on the multiplicity of equilibria that arises in classical models of bank runs we built a model of banks liquidity crises that possesses a unique bayesian equilibrium in this equilibrium there is a positive probability that a solvent bank cannot find liquidity assistance in the market we derive policy implications about banking regulation solvency and liquidity ratios and interventions of the lender of last resort furthermore we find that public bailout and private bail in involvement are complementary in implementing the incentive efficient solution and that bagehot s lender of last resort facility must work together with institutions providing prompt corrective action and orderly failure resolution finally we derive similar implications for an international lender of last resort ilolr jel g21 g28

a high frequency assessment of the ecb securities markets programme policy impact studies often suffer from endogeneity problems consider the case of the european central bank ecb securities markets programme if eurosystem interventions were triggered by sudden and strong price deteriorations looking at daily price changes may bias downward the correlation between yields and the amounts of bonds purchased simple regressions of daily changes in yields on quantities often give insignificant or even positive coefficients and therefore suggest that securities markets programme smp interventions have been ineffective or worse counterproductive we use high frequency data on purchases of the ecb securities markets programme and sovereign bond quotes to address the simultaneity and endogeneity issues we propose a vector autoregressive var framework estimated at several frequencies to better measure the smp impact and its persistence our results show that smp interventions have been effective in reducing yields of government bonds for the countries under the program

the buffer stock notion in monetary economics not the least of harry johnson s contributions to our discipline was the series of survey papers on aspects of monetary economics which he produced during the 1960s and 1970s it is no exaggeration to say that the way in which the literature of monetary economics is organised even now follows the design which johnson first set out in 1962 and built on in the subsequent decade nevertheless the subject has not stood still and one of the more interesting developments of the last few years has involved the introduction of what has been variously described as the disequilibrium money shock absorber or as i prefer to call it the buffer stock notion into monetary economics the development of this line of thought was getting underway before johnson s untimely death much of it indeed under the auspices of his own research programme at the lse even so this did not happen early enough for the relevant ideas to be put in their proper niche by johnson himself and the buffer stock approach is not yet fully integrated into the mainstream of monetary economics much of the relevant literature is empirical concerned with modelling particular aspects of the monetary experience of specific countries hence it is fragmented and contains few papers which attempt a coherent account of just what this approach is and how it relates to other approaches to monetary analysis although essays by goodhart 1982a b and judd and scadding 1982a contain important discussions of these issues to the best of my knowledge only jonson 1976a and knoester 1979a have devoted entire papers solely to this central issue and these are relatively inaccessible and hence less widely known than they deserve to be in this lecture i shall attempt to give a brief account of the essentials of this approach first i shall sketch out its microeconomic background and then i shall discuss those theoretical characteristics which differentiate it from the neo austrian analysis of robert e lucas jr and his associates as well as from the conventional keynesian approach to monetary economics last but by no means least i shall argue that it yields simple theoretical insights into important empirical and policy related issues which are troublesome for alternative approaches in short my tribute to harry

international price behavior and the demand for money oil prices commodity prices and american monetary policy the last operating through a variety of channels have all figured prominently in explanations of the international inflation process in the late 1960s and early 70s out major purpose in this paper is to test these various hypotheses we do so in the context of a reduced form rational expectations price equation which we estimate for the united states and seven other industrial countries using quarterly data for the period 1955 through 1976 the principal conclusion that emerges from this exercise is that movements in domestic money in these countries served as the key link in the inflation process the factors that produced these monetary changes however differed among countries price shocks of various sorts were clearly of secondary importance the other important set of conclusions concerns the demand for money in place of a traditional stock adjustment model we used gls with a second order correction for autocorrelation we believe this produced more plausible estimates of the parameters of the long run demand function and of the adjustment process itself

modeling financial sector joint tail risk in the euro area we develop a novel high dimensional non gaussian modeling framework to infer measures of conditional and joint default risk for numerous financial sector firms the model is based on a dynamic generalized hyperbolic skewed t block equicorrelation copula with time varying volatility and dependence parameters that naturally accommodates asymmetries heavy tails as well as non linear and time varying default dependence we apply a conditional law of large numbers in this setting to define joint and conditional risk measures that can be evaluated quickly and reliably we apply the modeling framework to assess the joint risk from multiple defaults in the euro area during the 2008 2012 financial and sovereign debt crisis we document unprecedented tail risks between 2011 2012 as well as their steep decline following subsequent policy actions jel classification g21 c32

risk endogeneity at the lender investor of last resort abstract to what extent can a central bank influence its own balance sheet credit risks during a financial crisis through unconventional monetary policy operations to study this question we develop a risk measurement framework to infer the time variation in portfolio credit risks at a high weekly frequency focusing on the eurosystem s experience during the euro area sovereign debt crisis between 2010 and 2012 we find that the announcement and implementation of unconventional monetary policy operations generated beneficial risk spill overs across policy portfolios this caused overall risk to be nonlinear in exposures in some instances the eurosystem reduced its overall balance sheet credit risk by doing more in line with bagehot s well known assertion that occasionally only the brave plan is the safe plan

who borrows from the lender of last resort understanding why banks borrow from the lender of last resort lolr during a nancial crisis is crucial to understanding the macroeconomic impact of such largescale interventions we document a strong divergence among banks take up of lolr assistance during the nancial crisis in the euro area as banks which borrowed heavily also used increasingly risky collateral we propose four explanations for this divergence
