on the link between exchange rate regimes capital controls and monetary policy autonomy in small european countries 1979 2000 we investigate international monetary policy transmission under different exchange rate and capital account regimes in eleven small open economies during the 1980s and 1990s we find no systematic link between ex post monetary policy autonomy and exchange rate regimes capital controls appear to have provided a degree of temporal insulation from foreign monetary policy shocks though not strict autonomy the results are consistent both with short term autonomy for small countries even under fixed exchange rates and an open capital account and with long term dependence under flexible exchange rates and an independent stability target results also indicate that euro area market interest rates are significantly more responsive to the development of the corresponding us rate than were the previous national rates

u s european interest rate linkage a time series analysis for western germany switzerland and the united states the authors investigate whether there was an international linkage of interest rates between the united states west germany and switzerland during the period of flexible exchange rates 1974 84 euro market rates and bond market rates are considered during the two subperiods of falling and increasing u s dollar dm exchange rates 1974 to 1978 and 1979 to 1984 spectral analysis and granger causality tests are applied and trivariate autoregressive models are estimated it is shown that a strong linkage exists during the second period but during the first subperiod there was no or only a weakly pronounced linkage copyright 1987 by mit press

the federal funds rate and the channels of monetary transmission the authors show that the interest rate on federal funds is extremely informative about future movements of real macroeconomic variables then they argue that the reason for this forecasting success is that the funds rate sensitively records shocks to the supply of bank reserves that is the funds rate is a good indicator of monetary policy actions finally using innovations to the funds rate as a measure of changes in policy the authors present evidence consistent with the view that monetary policy works at least in part through credit i e bank loans as well as through money i e bank deposits copyright 1992 by american economic association

does right or left matter cabinets credibility and fiscal adjustments abstract this paper tests the widely held assumption that left wing cabinets favor higher public spending and examines whether cabinet ideology affects the persistence of major fiscal adjustments in a panel of large fiscal adjustments in oecd countries during the last 40 years we find evidence that left wing and right wing cabinets are partisan the left tends to reduce the deficit by raising tax revenues while the right relies mostly on spending cuts our testable hypothesis is that cabinets can signal commitment by undertaking fiscal adjustments in ways that are not favored by their constituencies in other words the left gains credibility when it cuts spending while the right becomes more credible when it increases tax revenues probit estimates of the determinants of persistence in fiscal adjustments confirm that spending cuts by the left and tax increases by the right are associated with persistent adjustments the effect is significant for cuts in public spending public consumption wage or nonwage increases in total revenues direct taxes on businesses and other taxes we test for the role of several other determinants of persistence confirming that coalition and majority cabinets are associated with less persistence while periods of high or rising levels of indebtedness favor persistence the estimates of the impact of ideology and other variables on gdp and its components show that it is the size of the spending cut rather than cabinet ideology that is most important

employment policies wage formation and trade union behavior in a small open economy a model of trade union determined wages is developed which provides an explanation of underemployment based on optimizing behavior it is shown that fiscal policy will in general affect employment under perfect foresight and immediate wage flexibility future consequences of short run stabilization policies are discussed ratchet effects with respect to government expenditure and game theoretic interdependence between government and trade union behavior are emphasized if the trade union takes short run policy measures in order to increase employment as an indication of an employment stabilization rule the future behavior of the trade union changes and the result may be a decrease in long run employment

german dominance in the ems evidence from interest rates abstract the paper presents an empirical analysis of german dominance and asymmetries in the ems based on a dynamic system of equations explaining national money market interest rates the hypothesis of strict german dominance of the ems is rejected however there are some noticeable asymmetries in the ems germany is a relatively strong player and has been the least dependent country in the early phase of the system since 1983 german independence has diminished in contrast france throughout and italy in the early phase of the ems have been relatively weak players in the system

why the middle is unstable the political economy of exchange rate regimes and currency crises the contribution of sticky exchange rates to the rash of currency crises over the past decade has become a major topic of international monetary analysis and policy discussion while there is widespread agreement among economists that the middle of the exchange rate spectrum adjustable pegs is highly crisis prone in a world of substantial capital mobility jeffrey frankel has recently argued that surprisingly we lack a clear theoretical rationale for why this is so this paper attempts to fill that void it argues that frankel is correct in terms of economic analysis alone but that when political economy considerations are introduced then a satisfactory explanation is at hand key aspects of this political economy perspective are laid out and implications for exchange rate policy are considered the analysis suggests that for promoting currency stability the traditionally debated distinctions between crawling bands and managed floats are likely less important than the political environments in which they are operated

international transmission of inflation among g 7 countries a data determined var analysis abstract we investigate the international transmission of inflation among g 7 countries using data determined vector autoregression analysis as advocated by swanson and granger swanson n granger c 1997 impulse response functions based on a causal approach to residual orthogonalization in vector autoregressions journal of the american statistical association 92 357 367 over the period 1973 2003 we find that unexpected changes in us inflation have large effects on inflation in other countries although they are not always the dominant international factor similarly shocks to some other countries also have a statistically and economically significant influence on us inflation moreover our evidence indicates that us inflation has become less vulnerable to foreign shocks since the early 1990s mainly because of the diminished influence from germany and france

interpreting econometric evidence the behaviour of consumers expenditure in the uk abstract the dynamic models of consumers expenditure proposed by davidson et al 1978 and hendry and von ungern sternberg 1979 are re appraised in the light of hall s 1978 analysis of the empirical implications of the life cycle permanent income hypothesis in particular that the series for consumption should obey a random walk apart from trend in an attempt to reconcile the conflicting findings monte carlo experiments are used to demonstrate that if the davidson et al model were actually correct the hall model would appear to give a good description of the data and would probably not be rejected all the models are re estimated with new data for the uk and these data do reject a modified random walk specification in conclusion we discuss the issue of income exogeneity and comment on questions of model selection and interpretation

unit roots and granger causality in the ems interest rates the german dominance hypothesis revisited abstract the aim of this paper is twofold first it shows that a sufficient conditions for unit roots found in ar systems to persist in var systems amount to granger non causality in any direction among the variables involved this implies that a necessary condition for the disappearance of one unit root in a var system implies granger causality in at least one direction b for first order models with non explosive variables granger causality is also sufficient for cointegration and c causality and cointegration inference are strongly affected by the omission of an important causing variable second our new analytical framework allows us to formulate and test several new variations of the so called german dominance hypothesis in a unified cointegrating framework which we define as strong semi strong and weak types 1 and 2 german dominance in addition we allow for the possibility that the dominant player may lie outside the ems so that we introduce and test the us dominance hypothesis

dynamics of intra ems interest rate linkages anumber of previous studies have questioned the dominant role of germany within the european monetary system ems these conclusions are often based on empirical findings that the interest rates of ems member countries are not affected by german interest rates even in the long run in this study we demonstrate that intra ems interest rate differentials vis a vis germany exhibit mean reverting behavior characterized by long memory dynamics in a system incorporating six ems countries and one non ems country the u s a estimates from a fractional error correction model suggest the presence of short run intra ems monetary policy interdependencies but validate the german dominance hypothesis in the long run

the collapse of purchasing power parities during the 1970 s one of the striking facts concerning the relationship beiveen prices and exchange rates during the 1970 s has been the dismal performance of the predictions of the simple versions of the purchasing power parity doctrine ppp that doctrine in its absolute version states that the equilibrium exchange rate between domestic and foreign currencies equals the ratio of domestic to foreign price levels the relative version of the doctrine relates equilibrium changes in exchange rates to changes in the ratio of domestic to foreign prices during the 1970 s short run changes in exchange rates bore little relationship to short run differentials in national inflation rates and frequently divergences from purchasing power parities have been cumulative this paper reviews and analyzes the empirical record of exchange rates and prices during the 1970 s and the analysis is based on the experience of the dollar pound the dollar frecch franc and the dollar dm exchange rates section 2 presents the evidence on ppp during the 1970 s and contrasts it with the evidence from the 1920 s a period during which the doctrine held up reasonably well this analysis is relevant for assessing whether the flexible exchange rate system was successful in providing national economies with an added degree of insulation from foreign shocks and whether it provided policymakers with an added instrument for the conduct of macroeconomic policy the evidence regarding devia tions from purchasing power parities is also relevant for determining whether there is a case for managed float section 3 attempts to explain what went wrong with

interpreting the macroeconomic time series facts the effects of monetary policy existing theory and evidence on the effects of monetary policy are reviewed substantial room for disagreement among economists remains new evidence based on multivariate time series studies of several countries is presented while certain patterns in the data consistent with effective monetary policy are strikingly similar across countries others particularly the tendency of interest rate increases to predict high inflation are harder to reconcile with effective monetary policy

resistance to reform status quo bias in the presence of individual specific uncertainty comment why do governments so often fail to adopt policies which economists consider to be efficiency enhancing our answer to this question relies on uncertainty regarding the distribution of gains and losses from reform we show that there is a bias towards the status quo and hence against efficiency enhancing reforms whenever some of the individual gainers and losers from reform cannot be identified beforehand there are reforms which once adopted will receive adequate political support but would have failed to carry the day ex ante the argument does not rely on risk aversion irrationality or hysteresis due to sunk costs jel d72 f13 why do governments so often fail to adopt policies that economists consider to be efficiency enhancing this is one of the fundamental questions of political economy the answer usually relies on what may be

beyond spreads measuring sovereign market stress in the euro area abstract we develop a novel composite indicator to measure sovereign bond market stress in the euro area the indicator integrates yield and liquidity spreads along with volatility into an overall measure of sovereign market stress an application to the spillover literature suggests that stress mainly originates from a few countries but that spillover patterns also vary over time

interest rate linkages within the european monetary system further analysis j costas karfakis and demetrios m moschos 1990 examine the interest rate linkages within the european monetary system ems concluding that the german interest rate plays a dominate role within the ems the authors reexamine the interest rate linkages within the ems with the addition of the interest rate of the united states their results suggest that both the united states and german interest rates play an important but not dominant role in ems interest rate linkages copyright 1993 by ohio state university press

learning while voting determinants of collective experimentation this paper combines dynamic social choice and strategic experimentation to study the following question how does a society a committee or more generally a group of individuals with potentially heterogeneous preferences experiment with new opportunities each voter recognizes that during experimentation other voters also learn about their preferences as a result pivotal voters today are biased against experimentation because it reduces their likelihood of remaining pivotal this phenomenon reduces equilibrium experimentation below the socially efficient level and may even result in a negative option value of experimentation however one can restore efficiency by designing a voting rule that depends deterministically on time another main result is that even when payoffs of a reform are independently distributed across the population good news about any individual s payoff increases other individuals incentives to experiment with that reform due to a positive voting externality

interest rate linkages in the eurocurrency market contemporaneous and out of sample granger causality tests abstract this paper examines linkages among major eurocurrency interest rates during 1994 2002 eurocurrency interest rate causal linkages are found to be much stronger with additional allowance for contemporaneous causality test results than the inference based solely on granger causality tests the impact of u s interest rates is clearly not dominant in the eurocurrency markets while the japanese interest rates are found to be quite influential german interest rates both cause and are caused by several other eurocurrency interest rates by contrast interest rates on the new currency the euro do not have a substantial influence on other eurocurrency interest rates which underscores its emerging status

mundell s trilemma policy trade offs within the middle ground abstract mundells s trilemma makes strong categorial predictions on monetary policy trade offs where a small economy either has to adopt floating exchange rates or a closed capital account to establish interest rate autonomy however the trilemma is silent about a functional description of respective trade offs for intermediate middle ground policies accounting for the entire space of such policies we study monetary autonomy in an unrestricted and continuous manner for 20 mostly developed economies evidence suggests that interest rate dependence almost linearly increases with the fx stability indicator under financial openness thereby full independence would require an intensity of fx volatility which policymakers might hardly accept however this strong trade off can be relaxed efficiently by a moderate reduction of financial openness hence such a policy might offer some protection against the global financial cycle and leaves a considerable scope to combine a domestic monetary policy with a reduced fx rate variability

the effects of monetary policy using structural factor analysis the traditional vector autoregression var method is widely used to trace out the effects of monetary policy innovations on the economy however this method suffers from the curse of dimensionality so that in practice vars are estimated on a limited number of variables leading to a potential missing information problem in this article we use the method of structural factor analysis to evaluate the effects of monetary policy on key macroeconomic variables in a data rich environment this methodology allows us to extract information on monetary policy and its impact on the economy from a much larger data set than is possible with the traditional var method we propose two structural factor models one is the structural factor augmented vector autoregressive sfavar model and the other is the structural factor vector autoregressive sfvar model compared to the traditional var both models incorporate information from hundreds of data series series that can be and are monitored by the central bank in

do euro exchange rates follow a martingale some out of sample evidence abstract traditional autocorrelation and variance ratio tests are based on serial uncorrelatedness rather than martingale difference as such they do not capture potential nonlinearity in mean which could lead to misleading inferences in favor of the martingale hypothesis this paper employs various parametric and nonparametric nonlinear models as well as several model comparison criteria to examine the potential martingale behavior of euro exchange rates in the context of out of sample forecasts the overall evidence indicates that while martingale behavior cannot be rejected for euro exchange rates with major currencies such as the japanese yen british pound and us dollar there is nonlinear predictability in terms of economic criteria with respect to several smaller currencies

intertemporal speculation shortages and the political economy of price reform price controls often focus on commodities that are storable and can thus be used in intertemporal speculation second opposition to dismantling of controls is often based on claims of low supply response and greatly bolstered if a strong supply response fails to materialise this is especially relevant in eastern europe where experience with markets is limited we show the difficulties that these two factors create for gradual decontrol of prices we endogenise the probability of a collapse of the reform programme and show that such endogeneity in the presence of intertemporal speculation leads to a strong case against gradualism the smaller the initial price increase the lower the observed supply elasticity and the greater the probability that the programme of reform will be abandoned this implies that the policy that makes most sense from a microeconomic point of view decontrol immediately is also advisable from a macroeconomic point of view credibility problems which are at the core of the transitional output losses that characterise most stabilisation programmes will be much less under a cold turkey approach and so will therefore transitional unemployment

linkages among interest rates in the united states germany and norway the johansen multivariate cointegration methodology is used to analyze relationships among short term and long term interest rates in the united states germany and norway a variance decomposition approach is applied to estimate the proportion of each interest rate s forecast error variance attributable to innovations in the other interest rates impulse response functions are plotted to illustrate the speed with which interest rate events are transmitted between capital markets the analyses illustrate that us interest rates have a significant influence on both german and norwegian interest rates while the reverse effect is modest norway is also strongly exposed to german interest rate movements which reflects the consequences of a small country linking its currency to the value of european currencies

price level co movements within currency unions an alternative integration metric this paper analyses currency union integration by testing whether price levels in member countries possess a common stochastic trend the trace statistic test for cointegration proposed by johansen 1995 demonstrates the presence of such a trend for most unions a disaggregated analysis identifies a common stochastic trend for several though fewer than half of country pairs within a union some unions such as the eurozone have small shares of cointegrated country pairs yet the share of cointegrated country pairs is large relative to countries outside currency unions comparison to a control group country pairs where one country belongs to a given union and the other country does not indicates that the cointegration found within a currency union is a union specific trait and not a feature of the individual countries within the union these results provide an alternative metric to intraunion trade for gauging the extent of currency union integration

exiting a lawless state an earlier paper showed that an economy could be trapped in an equilibrium state in which the absence of the rule of law led to asset stripping and the prevalence of asset stripping led to the absence of a demand for the rule of law highlighting a coordination failure this paper looks more carefully at the dynamics of transition from a non rule of law state the paper identifies a commitment problem as the critical feature inhibiting the transition the inability under a rule of law to forgive theft this can lead to the perpetuation of the non rule of law state even when it might seem that the alternative is pareto improving

a model of rationing and labour supply theory and estimation a number of authors most prominently clower 1965 and leijonhofvud 1968 have interpreted keynes s theory of unemployment as a disequilibrium model nominal price and wage rigidity prevent the labour market from clearing the actual level of employment is given by the minimum of the effective demand for labour and the effective supply general disequilibrium models of income and employment determination have been developed by barro and grossman 1976 and malinvaud 1977 the model has been extended to the open economy by dixit 1978 and to a two period rational expectations context by neary and stiglitz 1979 the econometric implications of the disequilibrium approach have been developed by goldfeld and quandt 1972 maddala and nelson 1974 and rosen and quandt 1978 among others in summary the disequilibrium approach has provided a fruitful context for analysing macroeconomic behaviour in a competitive walrasian system the notional supply of labour is defined as the amount of labour a worker wishes to provide when he can buy and sell as much as he would like in all markets subject only to his budget constraint and given prices and wages the notional supply of labour then is given by l where 1 c attains the indirect utility function

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

wage inflation expectations and indexation abstract the study uses a direct measure of inflation expectations in testing the expectations augmented phillips curve with finnish data the impact of actual changes in prices is also analyzed in particular before and after the abolishment of idexation of wages in 1968 the results suggest that actual price changes dominated the wage formation prior to 1968 whereas after the abolishment of indexation the rate of unemployment and inflation expectations determined changes in money wages it seems that the expectations augmented phillips curve with unit coefficient for inflation expectations may be a good description of wage formation for the period after 1968

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

exchange rate stabilization in the erm identifying european monetary policy reactions abstract we develop the structural var models for european countries france denmark and germany during the erm period to examine the monetary policy reactions especially the within erm exchange rate stabilization in addition to analyzing the impulse responses and variance decomposition we present the full monetary reaction function in an interpretable manner without introducing additional assumptions the results suggest some asymmetry in exchange rate stabilization non german exchange rate stabilization is stronger than german exchange rate stabilization but do not support the hypothesis that german monetary policy was independent of the erm

a note on euroyen and domestic yen interest rates abstract this study examines interest rate transmission between the london euroyen market and the japanese domestic cd market the results which span 1984 through the beginning of 1993 indicate that these two interest rate series are cointegrated in the earlier part of the sample period causality is strongest from the euroyen market to domestic yen interest rates however strong feedback effects are observed in both directions in more recent years the use of both vector autoregressive modeling and cointegration analysis for forecasting is supported over random walk models

the interdependence of the term structure of eurocurrency interest rates abstract this paper investigates the interdependence of the term structure of eurocurrency interest rates our results suggest that when the central banks of switzerland and west germany increased their intervention in foreign exchange markets after the october 1979 monetary policy regime change in the usa a significant relationship developed between short term eurodollar interest rates and long term euromark and swiss eurofranc interest rates common cross country exchange rate expectation errors are exploited to improve the efficiency of the estimates using zellner s seemingly unrelated regressions

modelling the dynamic relationship between wages and prices in finland the purpose of this paper is to discuss finnish wage price dynamics with emphasis on the collective wage bargaining mechanism the results indicate that the dynamics of the system can be adequately described by means of a linear difference model with a rather sparse amount of lags completed by error correction mechanisms to ensure proper long term behavior specification of the collective wage bargaining procedure turns out to be a very important part of the model building another noteworthy feature is the stabilization period in 1968 69 during which a different data generating mechanism was in operation the results do not provide any evidence in favor of the argument that wage indexation prior to stabilization would have had a sizeable effect on the wage price mechanism in finland

the real time predictive content of money for output abstract data on monetary aggregates are subject to periodic redefinitions presumably in part to improve their link to measures of output money data are also revised on a regular basis taking these data imperfections into account we reassess the evidence on the marginal predictive content of m1 and m2 for real and nominal output in particular first by using the latest version of the data that is available and then using sequences of historical time series that would have been available to forecasters in real time we are able to provide a comprehensive assessment of whether money is useful for predicting output we conclude that the generally significant marginal predictive content of m1 or m2 for output that is found using a recently revised data set is not duplicated in a real time setting although m2 is shown to remain useful when 1 year ahead forecasts are constructed using fitted vector autoregressive models

economic reform and dynamic political constraints in this paper we examine the impact of political constraints on economic reform plans with special reference to the transition from centrally planned to market economies we analyse the problem of an agenda setting reform minded government facing a bureaucracy or industrial sector for which allocative efficiency requires redundancies and an increase in work intensity the government also tries to minimize the rents conceded to its heterogeneous workforce we examine two types of political constraints unanimity rule and majority rule both in a one period and a two period horizon the main results are the following first of all we show how adverse selection and time consistency may generate the widely observed feature of gradualism as an ingredient of an optimal reform second under a majority rule it is shown to be possible for the government to obtain a majority vote for a reform scheme that intertemporally hurts majority interests indeed the government can improve rent extraction through the strategic use of the threat of future proposals the group which expects to be in the minority tomorrow may accept concessions while its votes can be used to extract rents from another group these results suggest that in a dynamic context democratic constraints should not be overestimated as an obstacle against efficiency enhancing economic reforms the results of this paper may throw some light on the political economy of current reforms in eastern europe governments and political decision makers in general always face political constraints when elaborating reform proposals they know that the need to overcome potential opposition from various groups of the population constrains proposals for change political constraints vary depending on the specific institutional structure of society and are clearly different under a military dictatorship than under a parliamentary democracy the role of political constraints seems particularly important in eastern europe today where new democratic governments face the huge task of achieving the transition to a market economy while the introduction of democracy may have removed some important obstacles to economic change namely the veto power of a powerful nomenclatura under communist one party rule fears are expressed that it could potentially jeopardize economic reforms which may during the transition period hurt a majority of the population what can economic theory tell us about optimal economic reform under political constraints this paper starts addressing this ambitious question by looking at structural reform focusing on a restructuring of economic sectors which requires massive redundancies and a significant rise in labour productivity our model illustrates the case of planning

the multiscale causal dynamics of foreign exchange markets abstract this paper relies on wavelet multiresolution analysis to investigate the dependence structure and predictability of currency markets across different timescales it explores the nature and direction of causality among the exchange rates with respect to the us dollar of the most widely traded currencies namely euro great britain pound and japanese yen the timescale analysis involves the estimation of linear nonlinear and spectral causal relationships of wavelet components and aggregate series as well as the investigation of their out of sample predictability moreover this study attempts to probe into the micro foundations of across scale causal heterogeneity on the basis of trader behavior with different time horizons the examined period starts from the introduction of the euro and covers the dot com bubble the financial crisis of 2007 2010 and the eurozone debt crisis technically this paper presents an invariant discrete wavelet transform that deals efficiently with phase shifts dyadic length and boundary effects it also proposes a new entropy based methodology for the determination of the optimal decomposition level and a wavelet based forecasting approach overall there is no indication of a global causal behavior that dominates at all timescales in the out of sample analysis wavelets clearly outperform the random walk for the volatility series moreover the synergistic application of wavelet decomposition and artificial neural networks provided with an enhanced predictability in many forecast horizons for the returns these results may have important implications for market efficiency and predictability

transmission of u s monetary policy to europe and asymmetry in the european monetary system abstract this paper deals with the issues of the transmission of interest rates changes from the united states to europe and of the degree of asymmetry of the european monetary system i e of the extent of german leadership in determining the monetary policy of the ems zone if the transmission from the u s and the asymmetry of the ems are strong countries like france have almost no degree of freedom since both the short term and long term interest rates result from foreign influences and policies the authors try to answer those questions by estimating a model for the determination of the short term and long term interest rates in france and germany and of the dm exchange rate it appears that the assumption of asymmetrical functioning of the ems is confirmed that the dependence of long term rates on short term rates is weak in european countries and that the overall impact of changes in u s interest rates on european rates is limited

does the dm dominate the euro market an empirical investigation starting point is the german dominance hypothesis according to which germany has a dominant position within the ems this makes it impossible for other member countries to pursue their own monetary policies using monthly data of three month euro market rates from 1980 to 1988 for the u s germany the u k the netherlands france and italy we test this hypothesis in a multivariate cointegration framework we find that germany has a strong position in europe which is not restricted to the ems concerning long run development one might speak of a dominant position however there are short run relations between european countries which are not linked to relations with germany copyright 1993 by mit press

does the euro dominate central and eastern european money markets the so called german dominance hypothesis gdh claimed that bundesbank policies were transmitted into other european monetary system ems interest rates during the pre euro era we reformulate this hypothesis for the central and eastern european cee countries that are on the verge of accessing the eurozone we test this euro dominance hypothesis edh in a novel way using a global vector autoregressive gvar approach that combines country specific error correction models in a global system we find that euro area monetary policies are transmitted into cee money market rates providing evidence for monetary integration between the eurozone and cee countries our framework also allows for introducing global monetary shocks to provide at least tentative empirical evidence regarding the effects of the recent financial crisis on monetary integration in europe

gradualism versus big bang speed and sustainability of reforms a beneficial reform may be blocked by a majority if it is implemented by a big bang but the same reform may succeed with an optimally designed gradualist approach a gradualist approach can sometimes split opposition force and is in this sense more politically sustainable on the other hand if both approaches are politically preferred to no reform a big bang is often preferred to gradualism in terms of both political support as well as economic efficiency

a multivariate cointegration analysis of interest rates in the eurocurrency market abstract a multivariate cointegration methodology is utilized to analyze relations among interest rates on us dollars uk pounds german marks french francs and japanese yen in the eurocurrency market over a period with major capital market deregulations and increasingly globalized money market trading three major results appear it is appropriate to model these interest rates as a multivariate cointegrated system no interest rate may be excluded from the cointegrating relations a recursive cointegration approach indicates that the number of cointegration vectors increases in the later part of the sample period consequently this study supports the hypothesis of a substantial increase in euromarket interest rate comovements jel e40 f02 1997 elsevier science ltd

dominant interest and inflation differentials within the ems abstract this paper investigates nominal interest and inflation behavior in the ems between march 1979 and september 1989 using a modified version of principal components analysis neither over the whole period nor after march 1983 has the ems functioned as a dmark zone deviating movements in inflation and interest rates between ems countries still persist most important is the division between germany the netherlands and the united kingdom on the one hand and belgium france and italy on the other differences in deflationary policies between countries inside and outside the ems appear to be the most important determinant of this result

trade connections and interest rate linkages among asean japan and the usa an empirical analysis in the existing literature there have been only a limited number of efforts at empirically evaluating the degree of economic connections among asean countries the present study intends to fill this gap the study is conducted through an investigation of regional trade connections and interest rate linkages the results indicate that both the degree of trade interdependence and the interest rate linkages among asean nations are comparable to those among eec and nafta countries singapore plays a key role in asean economic relations different from eec and nafta asean appears to be heavily dependent on japan and the usa the two super economic powers outside the association

dynamics and causality in industry specific volatility abstract this paper presents comprehensive empirical evidence on the dynamics and causality within 30 us industry specific volatilities during july 1963 and june 2008 we find that linear trends are present in 17 of the 30 industry volatilities granger causality tests reveal that the industry of business supplies and the industry of finance are the most important lead indicators of industry volatilities to uncover contemporaneous causal relationships in the market we implement an emerging data driven method of directed acyclic graphs the results suggest that volatility shocks originating from business supplies machinery and consumer goods industries are sources of risks that affect most other industries by contrast volatilities in the two traditionally important industries oil and autos do not appear to have a substantial influence on other large industries in the contemporaneous time finally business equipment and services both containing information technology components are the most important driving forces of the industry volatility surge in the late 1990s

financial integration of east asian economies evidence from real interest parity in this article we investigate the financial linkages between the east asian economies with japan and the united states we test for long run real interest rate parity rip using an array of panel data techniques including recent techniques developed by breuer et al 2002 and carrion i silvestre et al 2005 this study offers two important results first the failure to account for structural breaks in the industrialized countries and asian emerging economies is likely to provide evidence of nonstationary series that are stationary second we found strong evidence that the parity condition holds in all the asian countries the failure of earlier studies to confirm mean reversion of real interest rate differential rid may reflect the choice of estimation testing procedure rather than any inherent deficiency in the rip

european integration and asymmetry in the ems abstract the empirical literature offers conflicting views of german dominance in the european monetary system we examine the validity of the german dominance hypothesis gdh by analyzing the responses of european central banks and money markets to monetary innovations originating both in europe european asymmetry and abroad international asymmetry our results reconcile the conflicting views in the literature the gdh is confirmed when the analysis is conducted with intervention rates before german unification results support european asymmetry with short rates before 1990 but not international asymmetry after 1990 the gdh is not supported by either set of rates

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

dynamic linkages among real interest rates in international capital markets abstract short run and long run dynamic linkages among weekly real interest rates for g 10 countries are examined using a variety of time series tests these tests give special attention to the time series properties of nominal interest rates ex ante expected rates of inflation and real interest rates term structure information is used to recover a theoretically consistent measure of ex ante expected inflation in sample and out of sample granger causality tests are also examined to evaluate lead lag relationships among real interest rates the results provide strong support for well integrated markets particularly in the long run the results imply leadership roles for the us in international asset markets
