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

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

is everything neutral in his well known analysis of the national debt robert barro introduced the notion of a dynastic family this notion has since become a standard research tool particularly in the areas of public finance and macroeconomics in this paper we critique the assumptions on which the dynastic model is predicated and argue that this framework is not a suitable abstraction in contexts in which the objective is to analyze the effects of public policies we reach this conclusion by formally considering a world in which each generation consists of a large number of distinct individuals as opposed to one representative individual we point out that family linkages form complex networks in which each individual may belong to many dynastic groupings the resulting proliferation of linkages between families gives rise to a host of neutrality results including the irrelevance of all public redistributions distortionary taxes and prices since these results are not at all descriptive of the real world we conclude

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

the perverse effects of partial labour market reform fixed term contracts in france we argue that the effects of a partial reform of employment protection by allowing firms to hire workers on fixed term contracts may be perverse the main effect may be high turnover in entry level jobs leading to higher not lower unemployment even if unemployment falls workers may be worse off going through many spells of unemployment and entry level jobs before obtaining a regular job considering french data for young workers since the early 1980s we conclude that the reforms have substantially increased turnover without a substantial reduction in unemployment duration if anything the effect on their welfare appears to have been negative

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

returns to education a further international update and implications this paper updates evidence on the returns to investment in education by adding estimates for new countries and refining existing estimates to bring the total number of country cases to over 60 the new cross country evidence confirms and reinforces earlier patterns namely that returns are highest for primary education the general curricula the education of women and countries with the lowest per capita income the findings have important implications for directing future investment in education which for efficiency and equity purposes should concentrate on these priority areas

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

deficits explicit debt implicit debt and interest rates some empirical evidence author affiliation zijun wang private enterprise research center allen building room 3028 texas am e mail z wang neo tamu edu corresponding author andrew j rettenmaier private enterprise research center allen building room 3028 texas am e mail a rettenmaier tamu edu acknowledgment we are grateful to kent kimbrough editor and two anonymous referees for their comments which significantly improved the paper financial support from the lynde and harry bradley foundation and the national center for policy analysis ncpa is acknowledged 1 introductionthe effect of government borrowing on interest rates has been a controversial issue for about three decades the federal deficits of the 1980s and the early 1990s caused speculation as to whether higher interest rates would follow the current deficits have renewed interest in the link to higher interest rates since the influential work of barro 1974 much of the discussion has focused on whether the ricardian equivalence hypothesis holds bernheim 1987 barth et al 1991 seater 1993 elmendorf and mankiw 1999 and engen and hubbard 2005 provide excellent reviews of the literature on the topic recent contributions include cebula 1997 gale and orszag 2003 laubach 2003 and ardagna caselli and lane 2004 among others although empirical evidence obtained in earlier studies is mixed as argued by gale and orszag 2003 major macroeconometric models imply an economically significant connection between changes in deficits and long term interest rates empirical evidence assembled by recent studies seems to lean toward the existence of the relationship but there is still no consensus about the magnitude of the effect a missing piece in the debate is a formal investigation of the effect of the implicit debt as embodied in unfunded obligations of social security and medicare theoretically it could be argued that because the ricardian equivalence proposition assumes that households are rational and make decisions for long horizons then like the often discussed public debt explicit debt the implicit debt computed based on 75 year 100 year or infinite horizons might also have a role to play in the determination of interest rates the point we raise here is not new in his 1996 paper reflections on ricardian equivalence barro writes t he basic invariance proposition for intergenerational transfers is that the government s transfers implied by budget deficits or pay as you go social security would be fully undone if family members were connected through voluntary transfers based on altruism p 2 more recently gokhale and smetters 2005 also note that social security s pay as you go financing may crowd out private saving and hence increase interest rates p 12 1 therefore it is problematic to test the ricardian equivalence hypothesis without considering the effect of the implicit debt empirically the explicit debt although large in absolute amount about 4300 billion by the end of 2004 is only a part of the federal government s total obligations according to the office of the chief actuary of the social security administration the social security program alone carries unfunded obligations ranging from about 3700 to 11 200 billion in present values at the beginning of 2004 under various assumptions these numbers are even larger if the trust fund balances are subtracted in particular projected old age survivors and disability insurance payroll tax income will begin to fall short of outlays in 2017 which means that social security will require transfers from general revenues in the next decade social security trustees 2005 while previous studies have investigated the effect of social security wealth on saving and consumption e

pay equality and industrial politics personnel managers often argue that equitable pay treatment manifested as wage compression is useful because it reduces disharmony among workers but it is far from obvious that a compressed salary structure is morale improving since better workers may feel disenchanted by this scheme however when workers rewards are based on relative comparisons salary compression reduces uncooperative behavior that is detrimental to the firm relative comparisons imply that some reference group must be selected the major result is that within the relevant groups some wage compression is efficient

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

the design of reform packages under uncertainty the authors present a model of large scale economic reforms modeled on the transition process in eastern europe with aggregate and individual uncertainty concerning the outcome of reforms the government is assumed to choose the speed and sequencing of reforms the authors compare big bang strategies with gradualist reform packages they show that gradualist reform packages may be easier to get started optimal sequencing of reforms should aim at creating constituencies for further reforms and gradualism may generate a higher investment response because of a lower option value of waiting than would a big bang approach copyright 1995 by american economic association

institutions and performance in european labour markets taking a fresh look at evidence this paper presents a selective survey of the recent literature on labour market institutions and offers new empirical eu based evidence on the impact of labour market reforms on employment and labour market adjustment although the literature traditionally treats labour market institutions as exogenous attention shifted recently towards understanding the underlying causes of specific institutional arrangements as a consequence the literature highlights the great importance of an efficient policy design exploiting these interactions wisely and identifies general principles for achieving an efficient policy design at both macro and micro levels although empirical evidence does not show a major change in terms of intensity of labour market reform after the setting of the economic and monetary union and the creation of the euro the reforms aiming at strengthening the labour market attachment of vulnerable groups tend to have been successful both in raising their employment and increasing labour market adjustment

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 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

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

estimating a household production function heterogeneity the demand for health inputs and their effects on birth weight the household production literature emphasizes that technical or biological processes condition input selection by households in their production activities along with prices and income exogenous variations in health to the extent that they are perceived by individuals heterogeneity lead to correlations between inputs and health outcomes that cannot be used to derive causal conclusions therefore estimates of health technology must be obtained from a behavioral model in which health inputs are themselves choices consistent estimates are reported of the effect of endogenous inputs such as medical care smoking and fertility on birth weight and fetal growth in the presence of health heterogeneity

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

risks and rewards gary becker s contributions to economics gary becker is one of the most original and influential economists of our age his originality lies in extending the frontiers of economics and broadening the range of important social science problems that are amenable to economic analysis he has gone against the grain of establishment thinking in the economics profession invariably choosing to work on problems that were considered beyond the boundaries of modem economics yet this work made close contact with many of the great economists of the past and many of the concepts he invented and developed are now widely if not routinely used in modem economics several of the approaches to problems he pioneered have evolved into fields and specialities in their own right that becker has had an immense intellectual impact and influence in the economics profession is supported empirically by the voluminous citations to his work over the years and in other ways obviously citation counts have well known difficulties and cannot prove anything by themselves but if used in conjunction with more fundamental evidence they do have the virtue of being quantifiable marshall medoff s 1989 1 recent citation study is one of the best available because citations are weighted by the importance of the journals in which articles appear among non nobel prize economists working in u s universities under 65 years of age becker ranks first in total citations over the 1971 85 period to which medoff s study refers and he is first by a very wide margin though the study is limited to economists in the united states it is clear that becker would rank at or very close to the top of any worldwide list furthermore becker s work is virtually all substantive economic analysis hardly any of it is devoted to the development of methodological tools or to surveys both of which gamer citations more easily and many concepts

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

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

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
