spurious volatility in historical unemployment data this paper shows that the stabilization of the unemployment rate between the pre 1930 and post 1948 eras is an artifact of improvements in data collection procedures prewar methods are used to construct postwar unemployment data that are consistent with the historical data the constructed postwar series is nearly as volatile as the pre 1930 unemployment data the constructed postwar data are systematically more volatile than the actual postwar data because the cyclical behavior of the labor force and productivity are misspecified in the construction procedures the relationship between the actual and constructed postwar unemployment series is used to construct new historical data

what explains recent changes in international monetary policy attitudes toward inflation evidence from developed countries abstract this paper identifies source s contributing to the recent international shift in monetary policy attitudes toward inflation data from 18 developed countries suggests that this shift is connected to the universal increase in policy responses to economic openness in the 1990s

the phillips curve the persistence of inflation and the lucas critique evidence from exchange rate regimes comment we present evidence from the united states and the united kingdom that the persistence of price inflation is significantly higher under managed exchange rate regimes than under gold based fixed exchange rate regimes these differences are also reflected in expectations augmented phillips curves we use a two country macro model with forward looking price setters to demonstrate that higher monetary accommodation of inflation and exchange rate accommodation of inflation differentials increase inflation persistence the evidence does not contradict this hypothesis it supports the hypothesis of forward looking price setters and highlights the empirical significance of the lucas critique jel e31 e42 f33

monetary integration and economic reform recent research in contract theory views ownership as a substitute for complete contracts here this approach is applied to monetary integration countries face a coordination problem conducting monetary policy negative spillovers ensure uncoordinated policy generates too high inflation ex ante policy makers can undertake politically costly economic reform this has a positive spillover because it improves the outcome of the monetary policy game ex post contracting over policy may be possible but it supposed that ex ante contracting over reform and monetary policy is not this paper analyses when monetary union is a good substitute for this inability to commit

asymmetric transmission mechanisms and the rise in european unemployment a case of structural differences or of policy failures abstract recent literature has emphasised how asymmetries in the relationship between inflation and unemployment make it more difficult to stabilise prices or reach full employment the same problem arises in europe due to large disparities in the rates of unemployment this time because of the integration of product markets coupled with imperfect factor mobility are these unemployment disparities due to an inappropriate choice of policies or to structural differences in market fundamentals we show that it is the latter which imposes the bulk of the inefficiencies in europe and that during the new ems period the european economies were characterised by a centering tendency in labour costs but a two speed regime has emerged since 1991

harvests and business cycles in nineteenth century america most major american industrial business cycles from around 1880 to the first world war were caused by fluctuations in the size of the cotton harvest due to economically exogenous factors such as weather wheat and corn harvests did not affect industrial production nor did the cotton harvest before the late 1870s the unique effect of the cotton harvest in this period can be explained as an essentially monetary phenomenon the result of interactions between harvests international gold flows and high powered money demand under america s goldstandard regime of 1879 1914

speculative bubbles in the ff dm parity during the 1980s it is often argued that exchanged rates volatility during the 1980s was too excessive to be attributed only to market fundamentals this paper investigates for speculative bubles in the franc mark exchange rate applying direct tests for determinate bubbles and indirect ones according to the issues of integration and cointegration for stochastic bubbles in the context of a sticky price monetary model no clear cut conclusions can be drawn from these tests although all of them indicate that the no bubble hypothesis cannot be easily accepted however any evidence for bubbles should be interpreted with caution since a possible misspecification of the model may produce misleading inferences

real exchange rates under the recent float unequivocal evidence of mean reversion standard multivariate tests of long run ppp may reject nonstationarity when a single real exchange rate series is stationary we apply a test where the null hypothesis is violated only when all series are stationary and reject nonstationarity for real dollar rates

monetary union and labor market reform abstract policy makers incentives to undertake costly labor market reform depend on the international monetary system a regime of noncooperative monetary policy is compared with monetary union we find that noncooperative policy leads to more reform of factors that affect the inflation bias which regime leads to more reform of factors affecting labor market flexibility depends on the size of monetary policy spillovers and the degree of correlation of supply shocks we show that monetary union produces higher expected inflation but a lower variance of inflation welfare can be higher or lower with monetary union

the lucas critique and the volcker deflation this paper examines in light of the lucas critique the behavior of the phillips curve and of the term structure of interest rates after october 1979 it starts with an informal account of the policy change and then discusses how we might expect these two relations to shift after such a change it finds little evidence of a direct effect of the policy change on the phillips curve at least until 1982 it finds substantial evidence of a direct effect on term structure this abstract was borrowed from another version of this item

international monetary regimes and incidence and transmission of macroeconomic shocks evidence from the bretton woods and modern floating periods this paper investigates the relationship between international monetary regimes and incidence and transmission of macroeconomic shocks within the context of an open economy macro model empirical results confirm monetary interdependence and lower incidence of monetary discretion under fixed exchange rates the average magnitude and dispersion of supply shocks in bretton woods and the subsequent float is comparable however the average magnitude and dispersion of real demand shocks under bretton woods seems higher overall the international monetary regime may pose important constraints to policymakers in open economies economists have long recognized the role of a flexible exchange rate regime in insulating economies and allowing independent pursuit of monetary policy however experience with floating rates in the post bretton woods period led many to question the merits of flexible rates with increased volatility in nominal and real exchange rates and the implied effects of this volatility on international trade flows although fixed rates reduce uncertainty and transaction costs compared with flexible rates these benefits may be outweighed by increased output volatility due to sticky prices and increased international interdependence if countries face idiosyncratic shocks independent monetary policy is needed to stabilize the domestic economy theoretical work on the effects of international monetary regimes has been inconclusive helpman 1981 dornbusch 1983 turnovsky 1983 and others provide evidence that exchange rate arrangements cannot be ranked unambiguously in terms of their impact on macroeconomic stability or domestic welfare instead several studies have analyzed macroeconomic performance under different historical exchange rate arrangements using macroeconomic data from the bretton woods and the subsequent floating regime baxter and stockman 1988 found no clear relationship between exchange rate flexibility and output stability or synchronization of the business cycle using bivariate vector autoregressions vars bayoumi and eichengreen 1994 analyzed the standard

budgetary policy and unemployment dynamics in an olg model with collective bargaining we consider a dynamic general equilibrium model with capital accumulation and collective wage bargaining and investigate how unemployment responds to structural shocks under two stylised budgetary policies under balanced budgets tax adjustments lead to higher unemployment on impact but enable a quick recovery of employment by contrast unbalanced budgets mitigate unemployment effects on impact but dynamics are more persistent due to weaker capital accumulation and future fiscal consolidations these results are consistent with empirical evidence on a positive cross country relationship between government borrowing and unemployment persistence this paper starts out from the well known fact that many european countries have suffered from persistently high unemployment over the past two decades there is a large literature which attempts to explain this development as resulting from a combination of structural shocks and mechanisms which make the effects of any such shifts more persistent one prominent branch of this literature stresses that adverse structural shocks tend to induce a slowdown in capital accumulation which reinforces the employment losses and adds to unemployment persistence bean 1989 benassy 1997 blanchard 1997 burda 1988 caballero and hammour 1998 daveri and tabellini 2000 similarly these studies point out that when the shock is over the recovery of employment depends critically on the speed with which investments in capital respond to the new situation the purpose of this paper is to reconsider this capital shortage hypothesis by linking it explicitly to the stance of fiscal policy to see the importance of fiscal policy in this context consider a government which faces an adverse structural shock such as a drop in employment due to a wage setting shock and decides whether it should keep its budget balanced or not this decision will affect the overall structure of assets in the economy i e the mix between capital and government bonds and this mix will in turn be an important determinant of the speed with which the economy can create employment once the shock is over in particular according to the capital shortage hypothesis the recovery in terms of employment is likely to take longer under a policy which temporarily accepts structural budget deficits particularly when crowding out effects have been substantial

exchange rate rules and macroeconomic stability this paper discusses exchange rate rules in their role as macroeconomic instruments we abstract throughout from the trend part of exchange rate behaviour a crawling peg necessitated by differences in trend inflation and emphasise instead the implications of exchange rate rules in providing flexibility of real wages or in affecting the stability of output or prices

evaluating the uncertainty in estimates of the economic impacts of bovine leukosis virus in u s dairy cows an examination of the economic impacts of bovine leukosis virus indicated that reduced milk production attributed to the presence of bovine leukosis virus in dairy cows reduced consumer surplus by 2 7 2 3 billion us bus and resulted in a total partial equilibrium loss of 720 560 million us mus to the u s economy in 1996 most of the economic surplus lost by consumers was transferred to producers whose economic surplus increased by 2 0 1 8 bus as a result of reduced milk production attributed to the presence of bovine leukosis virus in dairy cattle uncertainty analysis showed that an estimate of the milk production decline per percent increase in the prevalence of bovine leukosis virus in dairy cows accounted for most of the uncertainty in the economic impact estimates if bovine leukosis virus had not been present in u s dairy cows then milk production would have increased by 2 0 billion 1 5 billion kg the price would have fallen by 3 8 3 2 cents kg and the value of the milk produced would have decreased by 2 1 1 9 bus guidelines delineated by the international organization for standardization for evaluating and expressing uncertainty in measurement are discussed and proposed for use in the context of broad national estimates for which the economic impacts of bovine leukosis virus serve as an example the principal advantages of the methodology are the clarity and transparency of results and the ability clearly to identify major uncertainty contributors

regional inequalities and the business cycle an explanation of the rise in european unemployment demertzis m and hughes hallett a 1996 regional inequalities and the business cycle an explanation of the rise in european unemployment reg studies 30 15 29 the introduction of a system of fixed exchange rates in europe has succeeded in inducing price convergence amongst its participants but at the same time has increased the divergence between their rates of unemployment in this paper we attempt to measure the level of the inefficiency imposed on the labour markets as a result of having different labour market structures under one monetary policy and then use these results to provide a new explanation for the secular rise in european unemployment based on the degree of labour market heterogeneities and the asymmetries in wage settings in each market as a closer monetary union of its own regions the uk is used as a comparison for the europe wide results demertzis m et hughes hallet a 1996 les inegalites regionales et le cycle economique une explication de la montee du chomage en europe

the effects of supply shifts on producers surplus changes in the supply curve caused by technological improvements in production or changes in national policy may or may not benefit producers as a whole depending on the type of shift in the supply curve a structured analysis of different changes in the supply curve that model this situation is given and the change in producers surplus is examined depending on quantitative aspects of the supply and demand curves for supply and demand curves that are linear or power functions a small downward pivot of the supply curve will increase producers surplus only if the equilibrium point is far enough into the elastic region of the demand curve and any downward pivot of the supply curve will decrease producers surplus if the equilibrium point is in the inelastic region of the demand curve similar results are obtained for the more general case of convex supply and demand curves

the phillips curve parameter instability and the lucas critique empirical estimation of phillips curve relationships typically indicates the presence of parameter instability this is argued to be due to the fact that the parameters of these equations are reduced form rather than structural parameters estimation of a phillips curve model by methods which allow for time varying parameters permits investigation of the nature and timing of the structural breaks which generate instability this paper estimates such a model by the kalman filter using quarterly data over the period 1972 4 to 1993 3 we find evidence of a gradual decline in the private sector s assessment of the steady state inflation rate during the 1980s but little evidence of the sort of dramatic regime shift predicted by some of the more extreme rational expectations models

price changes supply elasticities industry organization and dairy output distribution long run price elasticities of milk supply are decomposed into price elasticities of yield herd size and farm population for northeastern u s dairy farms these elasticities are shown to vary with farm size because of size related differences in capital intensity specialization yield and herd size variability and rates of entry exit into dairy in the short run price responsiveness is shown to decrease with farm size in the long run large farms are shown to be most price responsive results suggest that lower milk prices could make revenue distribution less equal in both the short and long run by altering output and population distributions

common stochastic trends in international stock markets abstract this paper presents evidence concerning the number of common stochastic trends in the equity markets of the u s japan england germany and canada monthly and quarterly data from january 1974 through august 1990 on morgan stanley s capital international indices are used to compute johansen 1990 tests for common trends the results indicate the presence of a single common trend driving these countries stock markets estimates of the factor loadings suggest that this trend is most important in the japanese market and least important in the canadian market to interpret this evidence the paper demonstrates that under weak conditions the unit root and cointegration structure of stock prices should mirror the unit root and cointegration structure of their dividend payments the paper tests this prediction by constructing national dividend series from capital international s dividend yield data as well as by using gnp data as with stock prices the evidence points to a single common trend although the stochastic properties and relative importance of this trend differs somewhat from the trend in stock prices

european monetary unification a tour d horizon this article takes stock of the literature and debate over european monetary unification in contrast to other papers where it is argued that the issues and prospects remain shrouded in uncertainty i argue that in a number of important areas a reasonable degree of consensus now exists as the result of a decade of scholarship the subsequent stock taking concentrates on areas where significant questions remain starting with the implications of surrendering the exchange rate and an independent national monetary policy as instruments of adjustment the conduct of fiscal policy under the excessive deficit procedure and the stability pact and how quickly the european union is likely to develop an eu wide system of fiscal federalism to accompany its monetary union turning from fiscal to monetary issues i ask whether the european central bank ecb will be as inflation averse as the bundesbank what exchange rate policy the ecb will pursue and whether the euro will be a leading reserve currency i conclude with what may be the most contentious issue of all namely whether europe s monetary union could collapse after it begins

financial interdependence and the state international monetary relations at century s end as the twentieth century draws to a close one can find sharply contrasting views among leading scholars on almost every key issue in positive international political economy how strong are international as opposed to domestic influences on policy how important are issues of national security high politics versus economic considerations low politics what role do institutions international and domestic play in influencing and constraining the behavior of governments why is international cooperation rare but not unheard of the list goes on and on

empirical analysis of macroeconomic time series var and structural models abstract var and structural econometric models have complementary roles in the modelling of macroeconomic time series a constant parameter var provided it is statistically well specified constitutes a valid basis for testing hypotheses of dynamic specification exogeneity and a priori structure thus facilitating model evaluation as well as suggesting a potentially efficient model development strategy deterministic e g trends and regime shifts and stochastic e g integrated variables non stationarities are analysable within this framework and the johansen maximum likelihood procedure for cointegrated systems is used in an analysis of the determination of earnings prices productivity and unemployment in the u k

recent developments in macroeconomics underlying the existence of macroeconomics as a separate field of study are the phenomena of economy wide fluctuations of output and prices and sometimes persistent high levels of unemployment two basic views of macroeconomic behavior have persisted even as conceptual innovati ons and the application of more powerful analytic and empirical techn iques have brought significant changes in understanding of the macroe conomy copyright 1988 by royal economic society

how will emu affect inflation and unemployment in europe this paper explores how european monetary union will change the wage setting behavior of national labor unions we derive the impact of national inflation aversion and labor militancy on the performance of national labor markets under different monetary arrangements a common central bank raises inflation and unemployment if it acts as conservatively as national central banks however unemployment falls in countries that previously tied their monetary policy to the bundesbank we also examine the composition of emu and the influence of national labor market legislation jel classification e24 f02 f33

the new keynesian phillips curve from sticky inflation to sticky prices the new keynesian phillips curve nkpc model of inflation dynamics based on forward looking expectations is of great theoretical significance in monetary policy analysis empirical studies however often find that backward looking inflation inertia dominates the dynamics of the short run aggregate supply curve this inconsistency is examined by investigating multiple structural changes in the nkpc for the u s between 1960 and 2005 employing both inflation expectations survey data and a rational expectations approximation we find that forward looking behavior plays a smaller role during the high and volatile inflation regime to 1981 than in the subsequent period of moderate inflation providing empirical support for sticky price models over the last two decades a break in the intercept of the nkpc is also identified around 2001 and this may be associated with u s monetary policy in that period

correlations in price changes and volatility across international stock markets the short run interdependence of prices and price volatility across three major international stock markets is studied daily opening and closing prices of major stock indexes for the tokyo london and new york stock markets are examined the analysis utilizes the autoregressive conditionally heteroskedastic arch family of statistical models to explore these pricing relationships evidence of price volatility spillovers from new york to tokyo london to tokyo and new york to london is observed but no price volatility spillover effects in other directions are found for the pre october 1987 period article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

the political economy of the neoliberal transformation of french industrial relations the author advances the literature on the role of the state in the decentralization of industrial relations in france by providing a political economic analysis of right and left backed governments in recent decades while both have pursued reforms to reduce regulation and to increase labor market flexibility they have used the state apparatus in different ways to achieve these goals the right has reformed labor law by obtaining partial support from employers associations and unions the social partners the left by contrast has relied on decentralized bargaining with the social partners because its political base would not have accepted flexibility increasing legal reforms the author examines critical episodes of reform in collective bargaining unemployment insurance and employment protection laws to show how the state has intervened in different ways depending on the political identity of the governing coalition

causality links between consumer and producer prices some empirical evidence this paper reexamines the relationship between consumer and producer prices in the g7 countries united states canada germany france italy united kingdom and japan and it improves on the existing literature in two ways first it takes into account causality links arising from the transmission mechanism of monetary policy which are generally overlooked second it employs the causality testing method for unstable systems recently introduced by toda and yamamato 1995 which results in standard asymptotics thereby obtaining valid statistical inference the empirical results are consistent with the conventional wisdom according to which there is unidirectional causality running from producer to consumer prices bidirectional causality or even no significant links only being found when the causality links reflecting the monetary transmission mechanism are ignored

long memory and nonlinear mean reversion in japanese yen based real exchange rates abstract the extraordinary difficulty in uncovering parity reversion in yen based real exchange rates has often been ascribed to a missing trend variable this study identifies an alternative explanation and shows that the puzzling behavior of real yen rates may stem from long memory dynamics which undermine unit root tests in their ability to detect mean reversion the long memory findings are consistent with the long swings in yen exchange rates during the current float further analysis also reveals evidence of non monotonic reversion toward parity

does exchange rate pegging enhance credibility evidence from the european monetary system the european monetary system ems has been credited with immediately enhancing the credibility of onetary policy among its member countries however there is little empirical evidence to support this view this study provides evidence from exchange rate data that political actions taken to support the ems enhanced rate arangement further empirical results were sensitive to the specification of the estimating equations and varied dramatically if risk premia discounts were absent from estimating equations

monetary policy for inattentive economies we offer a contribution to the analysis of optimal monetary policy we begin with a critical assessment of the existing literature arguing that most work is based on implausible models of inflation output dynamics we then suggest that this problem may be solved with some recent behavioral models which assume that price setters are slow to incorporate macroeconomic information into the prices they set a specific such model is developed and used to derive optimal policy in response to shocks to productivity and aggregate demand optimal policy is price level targeting base drift in the price level which is implicit in the inflation targeting regimes currently used in many central banks is not desirable in this model when shocks to desired markups are added optimal policy is flexible targeting of the price level that is the central bank should allow the price level to deviate from its target for a while in response to these supply shocks but it should eventually return the price level to its target path optimal policy can also be described as an elastic price standard the central bank allows the price level to deviate from its target when output is expected to deviate from its natural rate

a critique of latent variable tests of asset pricing models abstract latent variable tests of asset pricing models make assumptions about the joint distribution of observable returns and unobservable benchmark returns these tests can falsely accept models when a mean variance efficient portfolio other than the benchmark satisfies the distributional assumptions imposed on the benchmark portfolio also because the assumptions are untestable there is no way to discover whether a model is being rejected because the assumptions are false without these assumptions however latent variable tests can be viewed only as tests of distributional hypotheses about mean variance efficient portfolios of unknown composition

on non uniqueness in rational expectations models an attempt at perspective abstract many macroeconomic models involving rational expectations give rise to an infinity of solution paths even when the models are linear in all variables some writers have suggested that this non uniqueness constitutes a serious weakness for the rational expectations hypothesis one purpose of the present paper is to argue that the non uniqueness in question is not properly attributable to the rationality hypothesis but instead is a general feature of dynamic models involving expectations it is also argued that there typically exists in a very wide class of linear rational expectations models a single solution that excludes bubble or bootstrap effects one that occur only because they are arbitrarily expected to occur a systematic procedure for obtaining solutions free from such effects is introduced and discussed in addition this procedure is used to interpret and reconsider several prominent examples with solution multiplicities including ones developed by fischer black and john b taylor

chronicle of a deflation unforetold suppose the nominal money supply could be cut literally overnight by say 20 what would happen to prices wages output the answer can be found in 1720s france where just such an experiment was carried out repeatedly prices adjusted instantaneously and fully on one market only that for foreign exchange prices on other markets such as commodities as well as prices of manufactured goods and industrial wages fell slowly over many months and not by the full amount of the nominal reduction coincidentally or not the industrial sector as represented by manufacturing of woolen cloths experienced a contraction of 30 when the government changed course and increased the nominal money supply overnight by 20 prices responded much more and the woolen industry rebounded

the adjustment of expectations to a change in regime a study of the founding of the federal reserve the founding of the federal reserve system in 1914 led to a substantial change in the behavior of nominal interest rates the authors examine the timing of this change and the speed with which it was effected they then use data on the term structure of interest rates to determine how expectations responded their results indicate that the change in policy regime was rapid and that individuals quickly understood the new environment they were facing copyright 1987 by american economic association

purchasing power parity in the long run a test of the dollar pound exchange rate 1890 1978 this paper tests the purchasing power parity ppp hypothesis by analyzing t he long run tendency of the dollar pound exchange rate using data sin ce 1890 two different models are considered 1 a na ive model and 2 a modified monetary model the conditions of propor tionality and symmetry cannot be rejected when using the naive model the final results using the monetary model however indicate that t he existence of permanent deviations from ppp cannot be ruled out copyright 1987 by ohio state university press

inflation and wage indexation in the postwar united states this paper examines the relationship between inflation and wage indexation in the postwar united states using data on the prevalence of cost of living adjustments in major collective bargaining agreements the author finds that increases in inflation precede increases in wage indexation but reductions in inflation do not precede reductions in wage indexation there is virtually no evidence that wage indexation affects inflation copyright 1995 by mit press

persistence in real variables under alternative exchange rate regimes some multi country evidence abstract in this paper we try to establish empirically whether a different degree of persistence is found in real variables under alternative nominal exchange rate systems the measure of persistence employed is the modified rescaled range statistic proposed by lo econometrica 1991 59 1279 1313 which tests for the presence of long range dependence after having accounted for a wide class of short memory processes the empirical results indicate a systematic increase in persistence in real variables under floating

the re emergence of ppp in the 1990s abstract in this paper we investigate purchasing power parity ppp in a panel with 17 countries for the period 1972 through 1996 the novel feature of our panel methodology is that results are invariant to the choice of a benchmark on numeraire currency in the panel we allow individual country effects in the relation between prices and exchange rates in this way we can identify the currency pairs for which ppp holds or does not hold we conclude that there is substantive evidence for ppp although not to the same extent for every currency evidence in favor of ppp is strongest for many exchange rates relative to the dmark and weakest for the japanese yen for this currency a trend like variable like productivity growth is missing

international transmission of stock market movements this paper investigates the international transmission mechanism of stock market movements by estimating a nine market vector autoregression var system using simulated responses of the estimated var system we i locate all the main channels of interactions among national stock markets and ii trace out the dynamic responses of one market to innovations in another generally speaking a substantial amount of multi lateral interaction is detected among national stock markets innovations in the u s are rapidly transmitted to other markets in a clearly recognizable fashion whereas no single foreign market can significantly explain the u s market movements also the dynamic response pattern is found to be generally consistent with the notion of informationally efficient international stock markets

interest rate seasonals and the federal reserve it is widely believed that one of the federal reserve s first important monetary policy achievements was the deseasonalization of interest rates the federal reserve supposedly accomplished this by introducing appropriate seasonal movements into the supplies of currency and high powered money this view implicitly assumes that there was no interaction between american and foreign financial markets two findings are reported that challenge this conventional view first interest rate seasonals disappeared in the united states and other countries at approximately the same time second interest rate seasonal ended approximately 3 years before the seasonal movements of currency and high powered money changed

the structure of interdependence in international stock markets abstract this study investigates the dynamic structure of nine major stock markets using an error correction model and directed acyclic graphs dag the dag representation provides a structure of causality among these markets in contemporaneous time building on this contemporaneous structure and the estimated error correction model innovation accounting techniques are applied the results show that the japanese market is among the most highly exogenous and the canadian and french markets among the least exogenous in our nine market study the us market is highly influenced by its own historical innovations but it is also influenced by market innovations from the uk switzerland hong kong france and germany the us market is the only market that has a consistently strong impact on price movements in other major stock markets in the longer run

inflation target shocks and monetary policy inertia in the euro area the euro area as a whole has experienced a marked downward trend in inflation over the past decades and concomitantly a protracted period of depressed activity can permanent and gradual shifts in monetary policy be held responsible for these dynamics to answer this question we embed serially correlated changes in the inflation target into a dsge model with real and nominal frictions the formal bayesian estimation of the model suggests that gradual changes in the inflation target have played a major role in the euro area business cycle counter factual exercises show that had monetary policy implemented its new inflation objective at a faster rate the euro zone would have experienced more sustained growth than it actually did

financial integration in european equity markets the final stage of economic and monetary union emu and its impact on capital markets this paper examines the extent of financial integration in european equity markets before during and after the adoption of the single currency on 1 january 1999 two groups of european economies are examined the first set comprises the member states of the european union eu that participated in the euro the euro 11 austria belgium finland france germany ireland italy luxembourg netherlands portugal and spain the second set consists of the remaining members of the euro 15 denmark greece sweden and the united kingdom along with norway and switzerland multivariate cointegration procedures granger causality tests and generalised variance decomposition analyses based on error correction and vector autoregressive models are conducted to examine long and short run relationships among these markets the results indicate that there is a stationary long run relationship and significant short run causal linkages between the equity markets of both the euro and non euro currency areas however while the large equity markets remain the most influential the lower causal relationships that exist between these and at least some middle belgium spain and netherlands and small ireland luxembourg finland and norway equity markets suggests that opportunities for international portfolio diversification in european equity markets may still exist

the rules of the game international money in historical perspective no world central bank issues a separate currency for commerce across national boundaries instead a system of national monies works more or less well in providing a medium of exchange and unit of account for current international transactions as well as a store of value and standard of deferred payment for longer term borrowing and lending how do national governments and banking institutions interact to provide international money for merchants and investors by necessity this monetary interaction changes with time place political circumstances and financial technology to better understand its historical evolution let us follow robert mundell and distinguish between a monetary system and a monetary order

new keynesian economics and the phillips curve models with sticky prices are an important part of new keynesian economics the author shows that several of the new keynesian models imply a formulation that is similar to the expectations augmented phillips curve of milton friedman and edmund phelps he then presents new estimates of the new keynesian phillips curve the author uses two proxies for price expectations survey based measures and an econometric based measure originally developed by bennett mccallum 1976 overall the results are consistent with the model but the survey based results are more precise suggesting that the surveys may be better measures of actual expectations copyright 1995 by ohio state university press

exchange rate regimes and inflation only hard pegs make a difference abstract using data from a large sample of developing countries from 1985 to 2001 we confirm that hard pegs currency boards or a shared currency reduce inflation and money growth there is no evidence that soft pegs confer any monetary discipline after other factors are controlled for inflation triggers regime switches under hard pegs monetary growth is unaffected by fiscal deficits or by inflation shocks under soft pegs as under floats increased fiscal deficits and positive inflation shocks are associated with higher monetary growth the apparently slower per capita output growth under hard pegs is explained by their geographical distribution jel classification f41

the advantage of tying one s hands ems discipline and central bank credibility abstract it is often argued that the ems is an effective disciplinary device for inflation prone countries in europe since it forces the respective policy makers to pursue more restrictive monetary policies than they would otherwise it is not clear however why these countries should submit themselves to such discipline this paper argues that to answer this question appropriately one must consider that ems membership brings potentially large credibility gains policy makers in inflation prone countries the reason is that not only it attaches an extra penalty to inflation in terms of real appreciation but makes the public aware that the policy maker is faced with such penalty and thus helps to overcome the inefficiency stemming from the public s mistrust of the authorities

changing inflation dynamics and uncertainty in the united states garch estimation we investigate recent changes in the level persistence and uncertainty of u s inflation despite the great strides in lowering inflation in the 1980s and 1990s we find that uncertainty has risen palpably in the current decade this is disturbing given the aforementioned findings of the negative impact of inflation uncertainty on output moreover analyzing both the standard consumer price index cpi and the cpi minus energy our results suggest that volatile energy costs contribute to the higher inflation uncertainty in the united states in the current decade

twin deficits apparition or reality this paper uses cointegration and multicointegration analysis to explore the issue of twin deficits for the usa in the post world war ii period the results suggest that prior to 1974 the systems of fiscal and foreign sector variables exhibit multicointegration these results do not rule out short run correlations between government deficits and external deficits however they do preclude the possibility that the twin deficit phenomenon describes a long run structural relationship in the post world war ii bretton woods era in the more recent period 1974 forward neither system exhibits evidence of multi cointegration but weak evidence of cointegration is present between fiscal deficits and trade deficits error correction models suggest that causality runs from internal to external deficits in the dynamic adjustment process this evidence provides some support for the notion that more recently fiscal deficits may have contributed to external deficits in combination with the results from the early s

the international price transmission in stock index futures markets i introduction numerous studies have investigated market linkages and price transmission mechanisms in major international equity markets employing the analytical framework of the vector autoregression var or its variant the error correction model ecm 1 studies such as von furstenberg and jeon 1989 eun and shim 1989 and koch and koch 1991 focus on the short run dynamic pattern of price transmission others like taylor and tonks 1989 and francis and leachman 1998 are primarily interested in the long run pattern of price transmission more recently an increasing number of studies explore both long and short run patterns of price transmission included in this last set are the works of malliaris and urrutia 1992 arshanapalli and doukas 1993 masih and masih 2001 and bessler and yang 2003 among others this study extends the examination of international price transmission to stock index futures markets the article contributes to the existing literature in three aspects first a relatively new empirical framework is applied to allow for inferences of price transmission at three different time horizons instantaneous the short run and the long run building on recent advances in statistical analysis of causal modeling using directed acyclic graphs dags as in spirtes et al 2000 pearl 1995 2000 and swanson and granger 1997 this study is able to explore the contemporaneous causal pattern underlying the correlations among market innovations the existence of strong contemporaneous correlations among market innovations has been well documented in the united states and international stock markets by agmon 1972 eun and shim 1989 koch and koch 1991 housbrouk 1995 and bessler and yang 2003 it is also well recognized by agmon 1972 849 and eun and shim 1989 246 that contemporaneous correlations among market innovations reflect the phenomenon that new information in one market is transmitted and shared by other markets in contemporaneous time due to immediate response to price changes between markets however more in depth analysis on exactly how instantaneous price transmission among market innovations is conducted in international equity markets has not yet been well addressed in the existing literature although bessler and yang 2003 touch on the issue the necessity of imposing constraints in the spirit of the block recursive structure noted by koch and koch 1991 in the dag analysis of var innovations is proposed and discussed thoroughly in this study second innovation accounting analysis is more thoroughly explored in the study innovation accounting tools i e impulse response analysis and forecast error variance decomposition have been commonly used to summarize the dynamic pattern of price transmission among international financial markets the importance of the factorization of innovations i e var residuals in yielding sound inference has been well acknowledged theoretically by bernanke 1986 sims 1986 and swanson and granger 1997 the application of the dag technique as discussed in swanson and granger 1997 and explained in the next section is further key to innovation accounting analysis in this study the instantaneous price transmission pattern between market innovations as identified by the dag analysis provides a data determined solution to the basic problem of orthogonalization of residuals from the ecm and thus is critical to impulse response analysis or forecast error variance decompositions swanson and granger 1997 argue that compared to the choleski decomposition the dag based structural decomposition is sensible but not subjective because it allows for the properties exhibited by the data although several recent studies such as those by bessler and yang 2003 bessler et al 2003 haigh and bessler forthcoming and yang 2003 have used the dag based structural decomposition in a similar setting the study is the first attempt responding to the suggestion by swanson and granger 1997 364 of investigating the empirical implications of the dag based contemporaneous causal modeling

the importance of composition of fiscal policy evidence from different exchange rate regimes abstract we study the macroeconomic effects of fiscal policies in an open economy we emphasize two transmission mechanisms the cost channel by which wage government spending and labor taxes raise the real wage firms must pay and the exchange rate channel by which the nominal exchange rate shifts induced by fiscal policy have real effects if some prices and wages are sticky the latter channel implies that changes in wage government spending or in labor taxation should have different effects under flexible than under fixed exchange rates in a 1964 93 panel of oecd countries we find significant evidence for both channels moreover we find that the real product wage and profitability are more responsive than quantities employment and output to fiscal policy innovations

testing monetary policy intentions in open economies 1 introductionthis article examines the relationship between economic openness and inflation performance among the most prominent research on this topic is the work by romer 1993 he demonstrates a negative relationship between economic openness and the inflation level his finding has also been viewed as supportive albeit indirectly of time consistency theory kydland and prescott 1977 1 romer 1993 argues that policymakers in more open economies have less incentive to adopt an expansionary monetary policy his argument is based on the assumption that monetary surprises in more open economies result in higher inflation for a given increase in output romer s finding that more open economies have lower inflation levels leads him to infer that this is evidence of time consistency in monetary policy practices however romer s work has not been generally accepted temple 2002 provides evidence that the openness inflation correlation does not stem from time consistency theory because the inflation level may not properly reveal the monetary authorities policy intentions temple questions this inference because it starts from a strong but unjustified assumption more open economies possess a relatively steeper phillips curve consequently temple proposes that the examination of the positive relationship between openness and the slope of the phillips curve is a fundamental condition for romer s argument he however finds little support for the positive relationship between economic openness and the slope of the phillips curve further work on the relationship of openness and monetary policy intentions comes from clarida gali and gertler 2001 2002 hereafter cgg in cgg 2001 the authors present a simple open economy model with a taylor type interest rate policy rule taylor 1993 the article concludes that the optimal monetary policy in an open economy has the same solution as that in a closed economy derived in cgg 1999 the authors also suggest that there is a direct link between the degree of economic openness and the aggressiveness of monetary policy they state that o penness does affect the parameters of the model suggesting a quantitative implication h ow aggressively a central bank should adjust the interest rate in response to inflationary pressures depends on the degree of openness cgg 2001 p 248 in subsequent work cgg 2002 revisit the issue based on a dynamic open economy new keynesian model and the role of monetary policy in open economies is refined consistent with the argument in cgg 2001 they find that the optimal monetary policy rule in an open economy is isomorphic to that in a closed economy in the nash equilibrium they also suggest that openness does not affect the optimality of a policy rule in such a scenario on the other hand economic openness does affect optimal monetary policy when the foreign optimal policy is endogenous in the domestic country s objective function this effect however is ambiguous in direction because the relationship between the degree of economic openness and the aggressiveness of monetary policy is determined by the relative size of trade and wealth effects of changes in foreign output this line of theoretical literature is limited and does not offer a definitive conclusion on the relationship between economic openness and monetary policy intentions our article provides an alternative empirical evaluation of the relationship based on prior literature we use inflation variability and persistence as the measures of monetary policy intentions one branch of the literature such as taylor 1999 cgg 2000 and owyang 2001 argues that aggressive monetary policy reduces the volatility of inflation for instance cgg 2000 estimate a forward looking taylor rule for the period between 1960 i and 1996 iv they use paul volcker s appointment as chairman of the federal reserve system as a regime shift to a more aggressive anti inflation policy stance

superexogeneity and the dynamic linkages among international equity markets abstract in this article we combine the johansen procedure for cointegration testing with tests of weak exogeneity and invariance in order to ascertain whether a system of equity markets is characterized by superexogeneity superexogeneity is rejected for the system comprised of stock indices of the us uk germany and japan this finding implies that agents participating in these financial markets are forward looking all markets are endogenous in our system and the assumption of stability of the asset demand function is questionable

european inflation dynamics abstract we provide evidence on the fit of the new phillips curve npc for the euro area over the period 1970 1998 and use it as a tool to compare the characteristics of european inflation dynamics with those observed in the u s we also analyze the factors underlying inflation inertia by examining the cyclical behavior of marginal costs as well as that of its two main components namely labor productivity and real wages some of the findings can be summarized as follows a the npc fits euro area data very well possibly better than u s data b the degree of price stickiness implied by the estimates is substantial but in line with survey evidence and u s estimates c inflation dynamics in the euro area appear to have a stronger forward looking component i e less inertia than in the u s d labor market frictions as manifested in the behavior of the wage markup appear to have played a key role in shaping the behavior of marginal costs and consequently inflation in europe

the logic and limits of desinflation competitive how could it be that starting with a keynesian marxian economic programme the socialists decided in 1983 two years after coming to power in france to adopt a diametrically opposed economic policy the desinflation competitive which has been maintained for fifteen years comprises an almost classic conservative policy substituting nominal stability wage restraint and public finance discipline for increased consumption nationalizations and devaluations this major shift in fact corresponds to the acknowledgement by the socialists of the new rules of opened and internationalized economies the desinflation competitive was certainly necessary in the early 1980s to correct severe imbalances however it appeared more and more irrelevant and counterproductive as inflation disappeared and unemployment kept on rising the failure of the desinflation competitive either to bring about disinflation other than through brutal market adjustments or to stop the rise in unemployment reveals the inability of the french socialists to build up genuine social democratic institutions and policies copyright 1998 by oxford university press

a test of price sluggishness in the simple rational expectations model u k i950 i980 a recurrent feature of the empirical output and price equations derived from simple rational expectations models is that the effects of nominal shocks persist for a long period of time in barro s i977 a unemployment equation unanticipated monetary growth influences unemployment with lags of up to 2 years in his price equation barro i 98 i unanticipated money has a lag of up to 5 years in the price equation fitted to uk data by attfield et al i 98i real money balances influence prices with a one year lag and unanticipated monetary growth influences them with a 2 year lag of course the existence of lags is neither necessary nor sufficient for the negation of the neutrality proposition of rational expectations models lucas i975 sargent 1979 and blinder and fischer i98i have provided rationales for the existence of lags in the supply equation and demonstrated their consistency with the neutrality proposition similarly the work of attfield et al i98i has indicated that lagged adjustments in the demand for money are also consistent with neutrality in both cases the combination of lagged adjustments with perfectly flexible market clearing prices yields all the neutrality propositions of the models of lucas and others however it is also the case that traditional keynesian type models with sluggish price adjustment imply lags in output and price equations the final equations with keynesian type lags may look very similar to the equations derived by lucas barro and others but their implications about the effectiveness of policy may be very different in the model with sluggish price adjustment supply is not equal to demand so some other rule will have to be found to determine employment and output anticipated monetary policy may be able to influence real economic variables if the employment and output rules are not specifically designed to offset the effects of anticipated policy for this reason a strong test of the neutrality proposition should be able to differentiate between different sources of lags and be able to identify them empirically if the test consists merely of a reduced form equation that identifies the lags and a rationalisation of them that is consistent with the neutrality proposition it can provide only weak evidence which may also be consistent

spillover effects in energy futures markets price discovery in crude oil and refined oil products has been extensively undertaken in organised futures markets for over a decade now there are two dominant such markets today the first one in the new york mercantile exchange and the second in london s international petroleum exchange with the demise of opec as the leading price setter for crude and products nymex light sweet crude and brent crude have usurped the role of benchmark grades for price setting to date considerable work has been done to scrutinise the degree to which these two markets price efficiently but little with regard to the way the two markets interact participants in these markets move with relative ease from one market to the other and usually take positions in both of them it is of interest therefore to investigate the information transmission mechanism by looking at spillover effects and perhaps identify which market is the true price leader this paper is a first attempt to look at such a problem in the energy market although similar studies have been done on stock market indices it is found that substantial spillover effects do exist when both markets are trading simultaneously although ipe morning prices seem to be considerably affected by the close of the previous day on nymex q 2001 elsevier science b v all rights reserved

nominal exchange rate regimes and the real exchange rate abstract two assumptions about the real exchange rate are common in the literature on international finance 1 the real exchange rate is a random walk 2 the time series properties of the real exchange rate depend on the nominal exchange rate regime this paper presents evidence that indicates that the random walk behavior of the real exchange rate is only a characteristic of the post world war ii period moreover our findings also suggest that what is crucial to the real exchange rate behavior is the particular historical period rather than the nominal exchange rate arrangement

capital accumulation and unemployment a tale of two continents in contrast to much recent work regarding the causes of european unemployment in this paper we emphasize the importance of capital accumulation but unlike the few previous studies which have examined the relationship between capital accumulation and unemployment we argue that what matters for the evolution of employment and the unemployment rate is not the absolute growth rate of a country s capital stock but its evolution relative to other countries capital stock the empirical validity of the above statement is demonstrated for almost all oecd countries using quarterly time series data for the period 1961 1995 more detailed evidence is also presented for germany japan and the united kingdom

nominal exchange rate regimes and the stochastic behavior of real variables abstract this paper examines the behavior of some key macroeconomic variables under alternative exchange rate regimes by looking at persistence volatility and the relative importance of symmetric worldwide versus asymmetric nation specific shocks as a driving force of business cycles the empirical evidence is not supportive of the nominal exchange rate neutrality hypothesis unemployment and real interest rates are more persistent under floating whereas industrial production and real exchange rates are less persistent also the conditional variance of the two latter variables and of the unemployment rate exhibits higher variability in the post bretton woods era furthermore principal components analysis shows that the flexible rate regime is characterized by increased international correlation of business cycles and that cyclic movements have become less country specific

functional forms exogenous shifts and economic surplus changes conditions for exact welfare measures in equilibrium displacement modeling are examined these relate to the functional form of supply and demand the nature of the exogenous shift and the definition of percentage changes approximation errors when these conditions are not met in empirical applications are investigated and analytical expressions for the errors derived significant errors are possible when a proportional shift is assumed the assumptions underlying alston and wohlgenant s empirical findings are identified the restriction that supply must be elastic is shown to be unnecessary

how the gold standard functioned in portugal an analysis of some macroeconomic aspects portugal was the first country in europe to join great britain in the gold standard in 1854 having abandoned the principle of free gold convertibility in 1891 by elucidating the historical choice of the gold standard by the portuguese authorities and analysing its macroeconomic behaviour we prove that it is a mistake to compare different monetary systems with the same indicators our examination of demand supply and monetary shocks in the context of a vector autoregression var model confirm the idea of appropriate application of the principles of classical economics to the gold standard in portugal we also prove that the principles of demand management were not compatible with the functioning of the gold standard

demand for farm output in a complete system of demand functions demand interrelationships for farm outputs that are theoretically consistent with consumer demand and marketing group behavior provide important linkages between retail and farm prices a conceptual model based on reduced form specifications for retail and farm prices is formulated and applied empirically to a set of eight disaggregated food commodities this approach circumvents the need for retail quantities which are frequently unavailable for disaggregated food commodities the results are consistent with theory and generally indicate significant substitution between farm and marketing inputs except for poultry derived demand elasticities are at least 40 larger compared to those derived assuming fixed proportions

competitiveness through disinflation an assessment of the french macroeconomic strategy france olivier jean blanchard and pierre alain muet over most of the last decade france has followed increasingly rigorous policies the hard franc approach has meant that external competitiveness is no longer sought through devaluation instead the new policy is to achieve a lower inflation rate than abroad in principle the competitiveness through disinflation approach should work and eventually bring down the unemployment rate which has remained broadly unchanged at a high level for many years while maintaining external balance this article investigates whether the policy is working inflation is lower than in germany profits have steadily increased and trade balance has been reestablished but unemployment is higher than in 1983 the policy has been more successful at bringing down inflation than at returning the economy to lower unemployment the adjustment process has been protracted credibility effects have not been fulfilled but nor however have fears that the drastic change of policy might prove unusually disruptive it simply turns out that the policy is working very slowly it would take an improbable 30 accumulated competitiveness gain to bring unemployment down by 3 which does not seem acceptable to france s trading partners

understanding the empirical literature on purchasing power parity the post bretton woods era abstract this paper argues that the empirical failure of statistical tests of ppp in post bretton woods data is largely due to the low power of the tests employed this result is demonstrated using monte carlo experiments on the size and power of different testing procedures a new procedure based on horvath and watson econometric theory 11 pp 984 1014 1995 has greater power than previous approaches using the horvath watson procedure we find moderate evidence in favor of ppp in the post bretton woods era

price inertia and policy ineffectiveness in the united states 1890 1980 this paper introduces a new approach to the empirical testing of the lucas sargent wallace lsw policy ineffectiveness proposition which compares the lsw hypothesis with an alternative that states that prices respond fully in the long run but only gradually in the short run to nominal aggregate demand disturbances the empirical equations estimated for a new set of quarterly data extending back to 1890 exhibit uniformly high responses of real output and low responses of price changes to anticipated changes in nominal gnp the paper compares and tests three alternative methods of introducing persistence effects into the lsw framework

testing long run purchasing power parity under exchange rate targeting abstract the present paper exploits the idea that empirical estimates of the long run ppp relationship may compound two distinct influences coming from the behavior of market participants and policy makers when the latter are targeting the exchange rate this tends to bias tests of long run ppp against its acceptance the validity of the theoretical arguments is assessed by drawing on the experience of two european union countries greece and france for the post bretton woods period estimation biases due to the omission of policy effects are found to be significant only in the case of greece for france our test results provide evidence bearing on the effectiveness of the competitive disinflation strategy pursued by the french authorities
