the role of real and monetary shocks in explaining business cycle fluctuations the essay brings empirical evidence to bear on the ability of real and monetary shocks to explain busines cycles using vector autoregressive techniques it is found that both real and monetary shoc

cyclical and causal relations between real wages and employment in the eu this paper analyses and compares the joint behaviour of real wages and employment over the business cycle in the european union eu economies using both annual and quarterly data since 1960 further investigation of the cointegrating properties and the existence of causal effects in the real wage employment relation is undertaken by employing appropriate var models the evidence suggests weak procyclical or acyclic behaviour of real wages relative to cyclical employment in the quarterly data and stronger procyclicality in the annual data thus confirming the dunlop tarshis result for the majority of the eu economies with a few exceptions no cointegrating relations were detected while the granger causality tests suggest either weak or lack of unidirectional causality finally the sensitivity analysis showed that the filtering method has not much influence on the results but the choice of deflator may overturn them in certain cases

the cyclical behavior of prices abstract the procyclical behavior of prices has been a staple of business cycle lore since the work of the early nber business cycle researchers this paper reexamines that empirical fact the aggregate data do not support procyclical price movements as a stable feature of the business cycle the only episode where it is a robust feature of the data is the period between the two world wars particularly the period of the great depression

markov switching causality and the money output relationship the causal link between monetary variables and output is one of the most studied issues in macroeconomics one puzzle from this literature is that the results of causality tests appear to be sensitive with respect to the sample period that one considers as a way of overcoming this difficulty we propose a method for analysing granger causality which is based on a vector autoregressive model with time varying parameters we model parameter time variation so as to reflect changes in granger causality and assume that these changes are stochastic and governed by an unobservable markov chain when applied to us data our methodology allows us to reconcile previous puzzling differences in the outcome of conventional tests for money output causality

does money matter in canada evidence from a vector error correction model this paper investigates the statistical properties of a set of canadian and u s economic time series and uses the data to address the question of the importance of monetary variables in canadian business cycle fluctuations the individual time series are found to contain unit roots but the data reveal the existence of several economically meaningful cointegrating vectors a multivariate vector error correction model is estimated and canadian velocity which appears as an error correction term is significant in the canadian output equation this supports the contention that monetary variables have predictive content for real output copyright 1989 by mit press

the causality relationship between energy consumption and gdp in g 11 countries revisited abstract this paper explores whether energy conservation policies can be implemented in countries with the same level of development that is is restraining energy consumption without compromising economic growth feasible in all industrialized countries a new granger non causality testing procedure developed by toda and yamamoto 1995 journal of econometrics 66 225 250 is applied to re investigate the relationship if any between energy consumption and income in 11 major industrialized countries the results clearly do not support the view that energy consumption and income are neutral with respect to each other except in the case of the united kingdom germany and sweden where a neutral relationship is found bi directional causality in the united states and uni directional running from energy consumption to gdp in canada belgium the netherlands and switzerland are found this indicates that energy conservation may hinder economic growth in the latter five countries further the causality relationship appears to be uni directional but reversed for france italy and japan which implies that in these three countries energy conservation may be viable without being detrimental to economic growth

job queues discrimination and affirmative action james r fain if employers have different becker type discrimination coefficients for different demographic groups then the implementation of affirmative action may have a differential impact on those groups we estimate two vector autoregressive models of the us economy including the unemployment rates of four demographic groups we find that a job queue existed before the implementation of affirmative action and that affirmative action changed the ordering of the job queue in manner that had a negative impact on nonwhite males we find evidence that affirmative action may have increased the unemployment rate of nonwhite males by increasing their duration of unemployment jel j71 j78 j64 j68 i introduction the relative status of demographic groups in the labor force has been undergoing significant change since the early 1960s throughout this period white females and racial minorities have experienced changes not only relative to white males but also relative to one another one such change is exhibited in relative unemployment rates figure 1 shows differentials in the smoothed unemployment rates using a 12 x 2 centered moving average for white females nonwhite males and nonwhite females for the years 1959 83 one can easily see that the relative unemployment burdens have varied over time focusing first on the two lines that are positive over the entire range one may see that prior to the late 1960s the status of nonwhite individuals especially nonwhite males relative to white females was improving however beginning in the late 1960s this trend reversed the unemployment rate differential between nonwhite males and white females increased from a low of 1 03 in july 1969 to a high of 11 12 in march 1983 similarly after declining during the 1960s the unemployment rate differential between nonwhite females and white females increased from a low of 3 49 in october 1969 to a high of 9 16 in august 1983 these reversals in trend indicate the status of white females relative to both nonwhite males and nonwhite females began improving in the late 1960s figure 1 also shows the status of nonwhite females improved relative to that of nonwhite males during the same time period the unemployment rate differential between nonwhite males and nonwhite females increased from a low of 3 13 in february 1968 to a high of 2 38 in february 1983 these three unemployment rate differentials all declined in the 1960s a time of tremendous social change and strong economic growth but all of these trends reversed direction in the 20 month period from february 1968 to october 1969 after the trend reversal the status of white females improved relative to both nonwhite males and nonwhite females and the status of nonwhite females improved relative to that of nonwhite males to put it another way nonwhite males lost ground relative to both nonwhite females and white females our goal is to examine what role if any the implementation of affirmative action in 1968 had in reversing these trends other possible explanations of the above noted reversal in trends certainly exist but several factors point to affirmative action as a potential cause of these changes first the timing is correct the trends reversed in close proximity to the implementation of affirmative action second whatever caused these reversals affected all minority groups did so within a short 20 month time span and its impact was sustained over a number of years a new federal policy designed to change the way firms hire minorities should have exactly this type of effect finally as we will argue below imposing affirmative action on discriminating employers will not benefit all demographic groups equally discriminating employers will continue to discriminate though the pattern of discrimination may change many of the traditional explanations of changes in relative unemployment rates are unlikely candidates to explain these significant and sustained reversals of longstanding trends

reconsidering the role of money for output prices and interest rates abstract new keynesian models of monetary policy downplay the role of monetary aggregates in the sense that the level of output prices and interest rates can be determined without knowledge of the quantity of money this paper evaluates the empirical validity of this prediction by studying the effects of shocks to monetary aggregates using a vector autoregression var shocks to monetary aggregates are identified by the restrictions suggested by new keynesian monetary models contrary to the theoretical predictions shocks to broad monetary aggregates have substantial and persistent effects on output prices and interest rates

lag length selection and tests of granger causality between money and income one of the most widely accepred relationships in macroeconomics is the positive relationship between the rate of growth of the money supply and the rate of growth of income a diversity of opinion arises however with the attempt to identify a causal relationship between these variables while friedman and schwartz 1963 initiated the empirical investigation of money income causality sims 1972 made the most significant contribution to this literature with a practical application of the criterion developed by granger 1969 for identifying a causal relationship since the appearance of sims s approach and an alternative one advanced by sargent 1976 many researchers have applied these techniques to the investigation of the causal relationship between money and income l with two exceptions hsiao 1981 and mcmillin and fackler 1984 these researchers have arbitrarily chosen the lengths of their distributed lags the purpose of this paper is to test for granger causality between money and income this paper differs from previous work in that considerably more attention is focused on the effect of the lag specification on the test results in particular we investigate the extent to which rules of thumb arbitrary lag specifications and

non competing persuaders abstract i study bayesian persuasion games with multiple persuaders in which the persuaders are non competing all persuaders want the decision maker to take the same action regardless of the state in the case of a single persuader it is known from previous research that the persuader optimal information design leaves the decision maker with no surplus in this paper i show that with two or more non competing persuaders and independent tests there are always equilibria in which the decision maker receives surplus if there is exogenous noise then the decision maker receives surplus in every symmetric equilibrium provided the number of persuaders is sufficiently large asymptotically the decision maker learns the true state in every pareto optimal symmetric equilibrium with infinitely many persuaders moreover with sufficient exogenous noise having more than one persuader not only improves the welfare of the decision maker but also improves the welfare of the persuaders

buying and selling attacks on fixed exchange rate systems abstract in this paper we show how rational expectations models of speculative attacks on fixed exchange rate systems can be extended to take into account the possibility that the central bank could be forced to either devalue or revalue essential to the analysis are the concepts of buying attack and selling attack by means of which we were able to describe how expectations about the future exchange rate are formed we also provide a discussion on the problem of uniqueness of the equilibrium that may arise in this kind of speculative attack models

a theory of expropriation and deviations from perfect capital mobility there are many reasons why commodity trade fails to equate the rewards to factors of production in different countries consequently there is an incentive for factor movements between countries while movements of factors especially capital are important in the world economy they have not been sufficient to equate factor returns among countries the failure of capital flows to equate returns to capital is frequently attributed to political risks and left outside the sphere of economic analysis specifically investments abroad especially in ldc s are said to be more subject to the risk of expropriation or at least to unpredictable changes in the tax and exchange control regime adopted by the host country fears of foreign investors have often been realised williams i975 estimates that about 20 of the value of foreign investments carried into or made during i956 72 in ldc s was expropriated without compensation in this period in the past researchers in disciplines other than economics have been responsible for most of the analysis of expropriations we argue that an important set of economic considerations affect the nature of these impediments to capital mobility and this paper provides a theory of expropriation based on maximising behaviour by host countries and investors we use this theory to identify industry and national characteristics increasing the threat of expropriation and implying large deviations from equal returns on capital and to examine host country and home country policies minimising distortions from the threat of expropriation three broad conclusions follow from the analysis first the threat of expropriation can significantly distort the international allocation of capital even if the act of expropriation is relatively rare in the extreme acts of expropriation would never occur in a world of perfect foresight and rational decision making yet actions by investors to ensure that countries do not expropriate would be distorting second the ability of a country s government to expropriate foreign investments may actually reduce its welfare furthermore a host may be better off if home governments can retaliate against an expropriating country indeed an increase in the penalty imposed on an expropriating country may increase its welfare a government s power to expropriate after investments are made may alasdair smith and an associate editor made numerous valuable suggestions we would also like to thank g m grossman r w jones l a sjaastad n h stern and j e stiglitz for comments much of eaton s work on this paper was completed while he was a visitor at the graduate institute for international studies geneva an earlier version of this paper appeared under the same title as rpds

balance of payments crises and devaluation the collapse of a fixed exchange rate is typically marked by a sudden balance of payments crisis in which speculators fleeing from the domestic currency acquire a large portion of the central bank s foreign exchange holdings faced with such an attack the central bank often withdraws temporarily from the foreign exchange market allowing the exchange rate to float freely before devaluing and returning to a fixed rate regime this paper links the timing of the initial speculative attack to the magnitude of the expected devaluation and to the length of the transitional period off loating an implication of the analysis is that there exist devaluations so sharp and transition periods so short that acrisis must occur the moment the market first learns that the current exchange parity will eventually be altered for sufficiently long transition periods the floating exchange rate overshoots its new peg before appreciating back toward it for shorter periods the rate depreciates monotonically to its new fixed level accordingly the central bank s return tothe foreign exchange market can occasion a capital outflow or a capital inflow this abstract was borrowed from another version of this item

money output and the expected real interest rate this paper tests the exclusion of lagged growth rates of money and output from regression equations with serially correlated disturbances for the expected real interest rate the authors empirical approach is an extension of the empirical strategies of eugene f fama 1975 and frederic s mishkin 1981 which invoke the orthogonality of the inflation forecast error to predetermined regressors under the maintained hypothesis of rational expectations they discuss the implications of their tests for simple real business cycle models copyright 1991 by mit press

money does granger cause output in the bivariate money output relation abstract a bivariate granger causality test on money and output finds statistically significant causality when data are measured in log levels but not when they are measured in first differences of the logs bootstrap simulation experiments indicate that most probably the first difference results reflect lack of power whereas the level results reflect granger causality that is actually in the data the reason for the lack of power in the first difference f statistic is that first differencing the data appears to entail a specification error by showing that money does granger cause output in the bivariate relation we remove a potential embarrassment for models that assign an important role to money in business fluctuations

breaking trends and the money output correlation this paper examines the impact on the money output correla tion of a univariate specification that allows time series to be characterized as stationary around a broken trend function though pretesting suggests that u s real output industrial production can be described as broken trend stationary this result has only limited impact on the money output correlation before 1985 there is a strong granger causal relationship between money and broken detrended output but not first differenced output even when different short term interest rates are used as regres sors however after 1985 this relationship weakens significantly whether or not one determines that output has a unit root

money market mutual fund maturity and interest rates the average maturity of money market mutual funds ranged from twenty nine to fifty three days during 1982 through 1990 according to the popular press changes in this time series provide interest rate forecasts the hypothesis is that fund managers lengthen their maturities when interest rates will be falling while the maturities are shortened when rate increases are imminent granger causality tests reject this hypothesis however there is a causal relation in the opposite direction interest rates granger cause average fund maturity indicating that on average fund managers respond to past rate changes copyright 1992 by ohio state university press

exploring the relationship between energy use and economic growth with bivariate models new evidence from g 7 countries abstract there is a rapidly growing literature on the interaction between energy use and economic development with many analysts drawing policy conclusions on the basis of granger causality tests that involve only an energy and an economic variable this paper attempts to demonstrate empirically that such studies although useful for certain applications may be of limited use for policy purposes after outlining theoretical and methodological issues associated with such approaches i apply bivariate energy economy causality tests for canada france germany italy japan the united kingdom and the united states using aggregate and sectoral data and three different modern econometric methods the results which are often contradictory or economically implausible illustrate explicitly that one should be cautious when drawing policy implications with the aid of bivariate causality tests on small samples i therefore underline the importance of utilizing as large sample sizes as possible and using multivariate models which are closer to economic theory accommodate several mechanisms and causality channels and provide a better representation of real world interactions between energy use and economic growth

government spending and taxation what causes what in the past few years as federal deficits have risen to high nominal levels economists have argued about the effect that raising taxes ostensibly to reduce deficits might have on government spending some economists including milton friedman have argued that raising taxes will simply lead to more spending others including james buchanan and richard wagner have said that the high deficits themselves have been responsible for the growth of federal spending and that if that spending had to be financed completely by direct taxes people would demand that the federal government spend less a third group led by robert barro says that increased taxes and borrowing are results of increased government spending in section ii we briefly review various hypotheses about the relationship between federal government spending and revenues section iii describes the testing procedure used to discriminate between these hypotheses the results of four tests are presented in section iv section v contains a summary and major conclusions to foreshadow what follows we find no evidence that higher real federal taxes today lead to either higher or lower federal spending tomorrow on the other hand we find strong evidence that higher spending now will lead to higher taxes later our results support a view of the world in which the political system somehow determines how much to spend and then looks for revenue sources to finance that level of spending including direct taxation borrowing and money creation we also find evidence that real federal revenues are positively affected by real gross national product gnp real federal spending also rises with real gnp but it appears to be independent of the rate of inflation

autoregressive modelling and money income causality detection abstract a step wise procedure based on granger s concept of causality and abaike s final prediction error criterion is suggested as a practical means to identify the order of lags of each variable in a multivariate autoregressive process the model seems useful because it can serve as a reduced form formulation to avoid imposing often spurious or false restrictions of the model it also provides a reasonably powerful test of causality the idea is applied to u s postwar money and income data it is found that between m1 and gnp a bivariate feedback model fits the data best between m2 and gnp a one way causal model from money to income performs better diagnostic checks applied to our model seem to indicate the adequacy of our approach

defence spending and unemployment rates an empirical analysis disaggregated by race this analysis brings u s time series evidence to bear on the relationship of defense spending and unemployment rates results indicate that defense increases during the 1970s were associated with improvements in the overall unemployment rate however during the 1980s such increases were associated with a worsening of the unemployment rate furthermore upon disaggregation into black and white unemployment rates it was found that in general whites were helped by defense spending increases while blacks were hurt this evidence offers support for the claim that an increasing complex military production process will lead to diminished employment gains particularly for minorities who are not proportionately represented in the high tech industries that serve the military copyright 1990 by oxford university press

money output granger causality revisited an empirical analysis of eu countries in this paper the evidence collected in the large literature on testing for granger causality from money to output is revisited using a broad data base of 14 eu countries plus canada the us and japan and quarterly data from the mid 1960s to mid 1990s a number of hypotheses from this literature is evaluated it is found that very few general conclusions can be sustained for instance in most countries it is not the case that the use of data in levels creates a bias in favour of finding granger causality effects of money on output compared to using differences neither does the significance of money lags decline when increasing the number of variables included in the model what appears to be robust though is that allowing for asymmetries clearly increases the likelihood of finding significant causality effects based on the granger causality test results a number of country groups are obtained using cluster analysis which are characterized by a similarly behaviour with respect to the money output

dynamics of the exchange rate in anticipation of pegging abstract this paper studies an economy in which agents expect the current floating rate regime to be interrupted on a specific future date by a transitional fixed rate policy when the new peg is not revealed in advance the path of the floating rate in anticipation of pegging is determined by the interaction between what agents perceive to be the objectives and the constraints of the central bank the paper highlights the role of the pegging date the duration of the fixed rate interval the quantity of reserves available to the authorities and the nature of policies expected after pegging is terminated

causal relationship between energy consumption and gdp growth revisited a dynamic panel data approach abstract this paper uses the panel data of energy consumption and gdp for 82 countries from 1972 to 2002 based on the income levels defined by the world bank the data are divided into four categories low income group lower middle income group upper middle income group and high income group we employ the gmm sys approach for the estimation of the panel var model in each of the four groups afterwards the causal relationship between energy consumption and economic growth is tested and ascertained we discover a in the low income group there exists no causal relationship between energy consumption and economic growth b in the middle income groups lower and upper middle income groups economic growth leads energy consumption positively c in the high income group countries economic growth leads energy consumption negatively after further in depth analysis of energy related data the results indicate that in the high income group there is a great environmental improvement as a result of more efficient energy use and reduction in the release of co2 however in the upper middle income group countries after the energy crisis the energy efficiency declines and the release of co2 rises since there is no evidence indicating that energy consumption leads economic growth in any of the four income groups a stronger energy conservation policy should be pursued in all countries

financial market variables do not predict real activity i introduction the past decade has seen an extensive empirical reassessment of the information content of financial market variables believed to be sensitive to monetary policy particularly provocative are papers suggesting that some interest rates and interest rate spreads contain more information about economic activity than monetary aggregates this paper reviews important methodological pitfalls in these studies we then show that none of the commonly employed indicators of monetary policy contain incremental information useful in forecasting real economic activity as measured by industrial production two conclusions are possible either monetary policy innovations have no significant real effects or we collectively have failed in our efforts to measure monetary policy the money income causality literature spawned by christopher sims in the 1970s has broadened in recent years to encompass a diverse set of measures of monetary policy more comprehensive and sophisticated empirical assessment strategies and a richer array of explanations for observed correlations between financial market variables and economic activity early contributors to this literature such as stock and watson 1989 friedman and kuttner 1992 and bernanke and blinder 1992 present evidence that particular interest rates and spreads not only dominate monetary aggregates as predictors of economic performance but are remarkably powerful predictors stock and watson 1989 and friedman and kuttner 1992 demonstrate that the spread between the interest rates on commercial paper and treasury bills is highly significant in explaining movements in real activity while bernanke and blinder 1992 made an equally convincing case for the federal funds rate these conclusions are qualified however in subsequent work both bernanke 1990 and stock and watson 1993 for example point out that the predictive power of the paper bill spread and interest rates more generally weakened during the second half of the 1980s and the early 1990s the results reported in these and related papers form the empirical core of the debate over the relative merits of various interest rates spreads and monetary aggregates as indicators of the stance of monetary policy subsequent empirical work has seen a shift from atheoretical to structural vector autoregressions strongin 1992 gordon and leeper 1994 and bernanke and mihov 1995 for example focus on more refined measures of monetary policy derived from explicit models of the reserve market and central bank operating procedures these papers address concerns that go beyond discriminating among variables on the basis of predictive power they grapple directly with the fundamentally difficult issue of identifying monetary policy shocks by positing and estimating structural models that take the form of identified vars the usefulness of these efforts as well as earlier efforts to measure monetary policy is in turn questioned by rudebusch 1996 who finds that the studies econometric results are fragile and at odds with other evidence on the nature of the fed s reaction function and monetary policy surprises the first part of our paper illustrates some of the methodological pitfalls common in the literature cited above and complements recent work by bernanke 1990 hess and porter 1993 thoma and gray 1995 rudebusch 1996 and emery 1996 we begin by demonstrating the advantages of rolling recursive regression techniques that directly and comprehensively address the question of sample sensitivity these techniques are used to illustrate the extreme sensitivity to sample period of the causality statistics and variance decompositions commonly used to assess the explanatory power of financial market variables indeed in the applications under review here such in sample measures of fit are sometimes heavily influenced by individual monthly observations

money and output viewed through a rolling window abstract we examine the extent to which fluctuations in the money stock anticipate or granger cause fluctuations in real output using a variety of rolling window and increasing window estimation techniques various models are considered using simple sum as well as divisia measures of m 1 and m 2 income prices and both the t bill rate and the commercial paper rate findings indicate that the relation between income money prices and interest rates is stable as long as sufficient data are used and that there is cointegration among the variables considered although cointegration spaces become very difficult to estimate precisely when smaller windows of data are used further both m 1 and m 2 are shown to be important predictors of income for the entire period from 1960 2 1996 3 based on modified versions of what we term the most damaging specifications from friedman and kuttner 1993 and thoma 1994 our new evidence is based in part on a rather novel model selection approach to examining the relationship between money and income 1998 elsevier science b v all rights reserved

causality and correlations of output and nominal variables in a real business cycle model abstract a dynamic general equilibrium economy in which output is exogenous with respect to money is calibrated and simulated following a procedure commonly used in the real business cycle literature it is then confronted with key comovement patterns of output and nominal variables in post war u s time series data the model economy performs well in matching second moment patterns involving output money and price the model economy with its embedded reverse causation from output to money also provides the means for carrying out a probabilistic appraisal of the observed money to output granger causality in u s data repeated applications of the granger causality test to simulated data lead to the rinding that money causes output more often than expected

evidence games truth and commitment an evidence game is a strategic disclosure game in which an informed agent who has some pieces of verifiable evidence decides which ones to disclose to an uninformed principal who chooses a reward the agent regardless of his information prefers the reward to be as high as possible we compare the setup where the principal chooses the reward after the evidence is disclosed to the mechanism design setup where he can commit in advance to a reward policy the main result is that under natural conditions on the truth structure of the evidence the two setups yield the same equilibrium outcome

identifying a distinctive competence forecasting ability in the money fund industry testing the causal link between a firm specific competence and its antecedents or consequences has become a key objective for strategy research over the past decade on one hand case studies can identify a competence but with their small sample size their retrospective research design and their tendency toward sampling on the dependent variable they can not reliably test the causal connection between a competence and its antecedents or its consequences on the other hand variance decomposition studies demonstrate the existence of firm specific performance differentials but have not identified which particular competencies are responsible for them the present paper avoids both of these problems by measuring a particular competence across a large sample of organizations over a long period of time so that a test of statistical causality can be applied to the relationship of this competence to both its antecedents and its consequences the particular competence studied is the ability of money market mutual funds to forecast changes in short term interest rates a competence known from prior research to be both valuable and rare in particular we test the effect of forecasting ability on the economic surplus generated by the fund and its growth conversely we also test the effect of growth on the subsequent development of forecasting ability copyright 2000 john wiley sons ltd

competition in persuasion we study symmetric information games where a number of senders choose what information to communicate we show that the impact of competition on information revelation is ambiguous in general we identify a condition on the information environment i e the set of signals available to each sender that is necessary and sufficient for equilibrium outcomes to be no less informative than the collusive outcome regardless of preferences the same condition also provides an easy way to characterize the equilibrium set and governs whether introducing additional senders or decreasing the alignment of senders preferences necessarily increases the amount of information revealed

the interactive and causal relationships involving precious metal price movements an analysis of the gold and silver markets to explain the interactive and causal relationships between gold and silver price movements time series procedures are used to identify reduced form parameters corresponding to a general arbitrage model enveloped in a framework of expectations about capital gains current price changes are conjectured to be functions of lagged and present values of the substitute precious metal prices and the interest rate plus lagged values of its own price to determine the appropriate number of lags to identify the appropriate interaction and to examine the exogeneity between the gold and silver prices and the rate of interest we use schwarz s bayesian information criterion and akaike s final prediction error criterion the resultant estimated model is simultaneous and provides information on participants average lead times in forming these expectations

beyond the purchasing power parity testing for cointegration and causality between exchange rates prices and interest rates abstract this paper reexamines the causality between the dollar and the yen in a multivariate framework with the aid of cointegration and error correcting modeling for the 1951 94 period the phillips perron tests and johansen s tests are performed while causality from interest rates to exchange rates is found in the short run no causality between prices and exchange rates is found in the short run however causality is found running from relative prices to exchange rates along with interest rates between the u s and japan in the long run which supports the long run ppp hypothesis

managing exchange rate crises evidence from the 1890s abstract this paper investigates the effectiveness of the monetary authority s borrowing policies in resolving exchange rate cises it shows why obtaining loans or lines of credit in foreign currency may avoid at least temporarily the devaluation of a fixed rate and discusses the problem of the optimal size of the loan and or the line of credit the analysis focuses on a particular episode of foreign exchange rate pressure during the troubled years between 1894 to 1896 the results suggest that the borrowing policy followed by the us treasury in those years was effective in avoiding the collapse of the united states gold standard and that the amount of the borrowing undertaken by the treasury might have been optimal

responses in output to monetary shocks and the interest rate a rational expectations model with working capital abstract empirical studies show that when the interest rate is included money loses its predictive power on output this paper explains this finding by using a rational expectations model where production decisions of firms require debt financed working capital the cost of working capital the interest rate affects the supply side monetary shocks affect the interest rate and thus affect the price and output produced by firms the model shows that this can cause the predictive power of monetary shocks on output to diminish when the interest rate is used in empirical analysis the model also alludes to the effects of monetary policy on the price level through the supply side cost push factors

money and output new evidence based on wavelet coherence abstract we reassess the relationship between money and output using quarterly data from the us economy we use several tools based on wavelets the wavelet power transform and the wavelet coherence with which we analyze this relationship in both time and frequency we find evidence of a weaker relationship within the great moderation as well as a stronger relationship during the great recession

collapsing exchange rate regimes some linear examples abstract we construct a pair of linear examples to study the collapse time of a fixed exchange rate regime the first example is a perfect foresight continuous time model which allows calculation of the exact collapse time and the tracking of reserves the second example is a discrete time stochastic model which yields an endogenous probability distribution over the collapse time and produces a forward discount of the exchange rate

a model of the demand for investment banking advising and distribution services for new issues this paper presents a theory of the demand for investment banking advising and distribution services for the case in which the investment banker is better informed about the capital market than is the issuer and the issuer cannot observe the distribution effort expended by the banker the optimal contract under which the offer price decision is delegated to the better informed banker in order to deal with the adverse selection and moral hazard problems resulting from the informational asymmetry and the observability problem is characterized the model demonstrates a positive demand for investment banking advising and distribution services and provides an explanation of the underpricing of new issues an investment banker performs three functions which may be of value to an issuer of new securities underwriting advising and distribution this paper presents a theory of the demand for investment banking advising and distribution services based on an informational asymmetry between an issuer of new securities and an investment banker ultimately a theory of the organization of the financial intermediary industry is required that would predict which firms would use which types of financial intermediaries for which purposes and which firms would raise capital without engaging the services of a financial intermediary only a limited set of such predictions are developed here in the context of a model of a fixedprice offering under a negotiated contract in which the investment banker is

borrowing to defend the exchange rate and the timing and magnitude of speculative attacks abstract the paper analyses the implications for the timing and magnitude of a speculative attack on a fixed exchange rate of government borrowing to increase the stock of international reserves it is shown that such borrowing reduces the likelihood of an early collapse and increases the likelihood of an eventual collapse the magnitude of the speculative attack also increases

does money still matter for u s output abstract in this note we use an out of sample approach to investigate whether money growth granger causes output growth in the united states we find that after the great moderation the granger causal role of money appears to have vanished completely

larger crises cost more impact of banking sector instability on output growth we propose a method for calculating the macroeconomic costs of banking crises that controls for the downward impact of recessions on banking activity in contrast to earlier research we estimate the cost of crises based on the size of banking crises the extent of a crisis is measured using banking sector aggregates the results based on our method and data from over 100 banking crises suggest that the size of a crisis matters for economic growth lower credit deposit and money growth during crises cause gdp growth to decline

more evidence on the money output relationship i introduction the empirical relationship between money and real output continues to produce conflicting evidence stock and watson 1989 using monthly u s data for the period 1960 85 report that while actual money growth m1 does not granger cause the growth of industrial production its detrended component does krol and ohanian 1990 internationalize stock and watson s study and find that both actual and detrended ml growth granger cause output growth in the u k but that neither series affects output growth in japan canada and germany friedman and kuttner 1992a 1992b 1993 question the role of money in explaining output behavior they report 1993 that even though the stock watson specification is used simply updating the sample through 1990 yields the result that detrended m1 growth no longer explains output growth friedman and kuttner also argue that the commercial paper rate or the spread between the three month treasury bill and the commercial paper rate provides a better gauge for output s reaction to monetary policy changes replacing the treasury bill rate used by stock and watson with the commercial paper rate or the spread friedman and kuttner find that m1 growth has no marginal explanatory power over output a feature of recent investigations of the money output link is the general use of a var specification based on the presumption that the series are difference stationary e g feldstein and stock 1994 several recent studies however have questioned this presumption due to the low power of unit root tests dejong et al 1992 dejong 1992 dejong and whiteman 1991a 1991b and rudebusch 1993 these studies suggest that it is difficult to distinguish between difference stationary as the null and trend stationary as the alternative hypothesis given the uncertainty about the existence of a unit root in economic time series we re examine the money output relation by specifically considering the affect of assuming that the series are trend stationary or difference stationary such an investigation is important to determine if permanent temporary changes in money and other series create permanent temporary shifts in real output for example if real output and money contain a unit root i e they are best represented by the difference stationary model permanent money shocks may produce permanent shifts in output put another way permanent money shocks may have a long run impact because they affect the stochastic trend component of output and thus change the output level for all future horizons on the other hand if output and other series are represented by a trend stationary model fluctuations around a trend level of these series are stationary mean reverting under this model a transitory money shock may only have a short run impact on output as it quickly returns to its trend level to analyze the sensitivity of results to different stationarity assumptions used we estimate two var systems one system uses the log levels of the variables along with a deterministic time trend the other uses the log difference of the series and excludes the trend term the first system represents the trend stationary specification and the second one represents the difference stationary specification there is some evidence that the money output link may be sensitive to the presence of a deterministic trend term e g eichenbaum and singleton 1986 stock and watson 1989 even so our study provides a direct comparison based on identical data sets of the effects that the two different stationarity specifications have on the money output results while testing the robustness of the money output connection is our main focus we also provide some different perspectives on the debate one is to use both long and short term data sets most studies limit the analysis to quarterly data from the post 1960 era we study the link between money interest rates and output using annual data over the extended period 1915 1993

the belmont morgan syndicate as an optimal investment banking contract this paper represents an application of theories of speculative attacks on fixed exchange rate regimes and of optimal investment banking contracts to the belmont morgan syndicate of 1895 this syndicate contracted to supply gold to the u s treasury and to bear the risk of maintaining a fixed exchange rate for six months our purpose is to determine the extend to which such simple theories can elucidate both the events of that period and the features of the belmont morgan contract

detrending and the money output link international evidence 1 introduction and background the question of whether there exists an empirical link between nominal money and real output has been subjected to a variety of modern econometric techniques producing conflicting results for example stock and watson 1989 use a vector autoregressive var model that accounts for several important economic variables and find that money exerts a statistically significant effect on real economic activity friedman and kuttner 1992 1993 on the other hand show that using the same specification as stock and watson but extending their sample through the 1980s obviates the money income link friedman and kuttner s results indicate that interest rates are relatively more useful in explaining movements in output thoma 1994 also reports that changes in money do not have a statistically significant impact on output in the united states more recent studies both theoretical and empirical also have shown money to have little or no direct effect on economic cycles rudebusch and svensson 1999 2002 for example conclude that the behavior of money real or nominal has no marginally significant impact on deviations of real output from potential the output gap once past movements in the gap and real rates of interest are accounted for such findings on the basis of what meyer 2001 refers to as the consensus macro model have achieved an influential position among macroeconomists and policymakers 2 other studies challenge the argument that money does not affect real output an early study by christiano and ljungqvist 1988 using a bivariate var model reports the existence of a statistically significant money to output relation in u s data davis and tanner 1997 using monthly u s data extending back to the mid 1800s find that even after interest rate effects are allowed for money remains statistically significant in explaining short run movements in real output using a rolling regression approach swanson 1998 reports a statistically significant relation between money measured as simple sum aggregates and as divisia measures and output even after an interest rate spread variable is added to the model hafer and kutan 1997 considered whether different stationarity properties of the data have influenced reported outcomes since most prior studies assume difference stationarity hafer and kutan demonstrate that estimating var models that include money and interest rate variables under the existence of trend stationarity can dramatically affect the conclusion indeed they find that using a trend stationarity assumption yields the finding that money significantly affects real output movements in the united states a common characteristic of this literature is its focus on the united states there are a few exceptions for example krol and ohanian 1990 apply the stock watson specification to data for canada germany japan and the uk although money actual and detrended significantly affects output in the uk krol and ohanian find no such affect in japan canada and germany they conclude that although detrending the growth rate of u s money affects conclusions about the role of money little is gained from this approach when applied to the other countries another exception to the u s focus is a recent study by hayo 1999 using data from 14 european union eu countries plus canada japan and the united states hayo shows that money output test results are not sensitive to the use of data in levels versus data in differences an obvious question to ask then is whether nominal money is relatively more useful than interest rates in explaining movements in real output across a wider variety of countries that includes industrial and developing economies although the studies of krol and ohanian and hayo represent a broader analysis they too focus on the money output relation in relatively industrialized financially developed countries
