the relative forecasting performance of the divisia and simple sum monetary aggregates this paper provides direct evidence on the forecasting performance of the divisia monetary aggregates relative to the traditional simple sum monetary aggregates it is shown that forecasts of u s real gdp from a four variable vector autoregression var are most accurate when a divisia aggregate is used rather than a simple sum aggregate particularly at broad levels of aggregation further the two m1 aggregates relative to the broader aggregates are superior predictors of the gdp deflator with a slight edge going to divisia m1 over simple sum m1

analysts interim earnings forecasts evidence on the forecasting process existing empirical evidence indicates that analyst forecasts of corporate earnings do not meet the strict rationality standards prescribed by econometric tests of the rational expectations hypothesis 1 in this paper we address the question of whether the expectation formation process underlying analyst forecasts is adaptive or whether these forecasts are influenced by noninformational factors such as incentives arising from the market for their forecasts o brien 1988 lin and mcnichols 1993 francis and philbrick 1993 and dugar and nathan 1992 and interaction between judgmental and or statistical forecasting methods bunn and wright 1991 fan 1990 and hoerl and kennard 1970 the rejection of rational expectations gives rise to two views of the forecasting process of analysts the first based on an informational argument is that the forecasting process is adaptive marcet and sargent

the empirical relationship between money prices and income revisited this article investigates the relationship between sum divisia and monetary velocity money prices and income using the notion of granger 1969 causality this is achieved by evaluating empirically using dickey fuller unit root tests whether the macroeconomic time series under consideration are trend stationary or difference stationary and by conducting tests using three different ad hoc lag lengths 8 6 and 4 quarters as well as a statistically determined using akaike s 1969a b final prediction error criterion lag structure

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

directional preferences information processing and investors forecasts of earnings this paper investigates the effects of preferences on judgments in an investing context where investors should be motivated to interpret information objectively yet have clear preferences with respect to what the information they are evaluating conveys i e a gain or a loss on their investment the results of the experiment are consistent with theories of motivated reasoning that predict when and in what manner directional preferences affect how information is processed specifically investors are motivated to agree unthinkingly with information that suggests they might make money on their investment but disagree with information that suggests they might lose money in disagreeing long investors expect earnings to be relatively high and short investors expect earnings to be relatively low these results have implications not only for understanding investor behavior but also for understanding the biased behavior of market participants who face conflicts of interest such as analysts managers and auditors by providing direct evidence that such behavior can arise for purely psychological reasons

rules and discretion with noncoordinated monetary and fiscal policies the time inconsistency of optimal monetary policy is due to the effects of tax distortions thus the issue of how to improve upon the time consistent suboptimal monetary policy is related to that of the coordination of monetary and fiscal policy we present a model with three players the central bark the fiscal authority and wage setters in which distortionary taxes are explicitly modelled we show that binding commitments to monetary rules are not necessarily welfare improving if monetary and fiscal policy are not coordinated we also examine the effects of different degrees of independence of the central bank

corruption a review as is increasingly recognised in academic literature and by international organisations corruption acts as a major deterrent to growth and development the aim of this survey is to organise and summarise existing theoretical and empirical work on corruption with a view to identifying opportunities for further research the paper begins with a brief overview of key definitions of corruption and then turns to a review of the factors that favour or deter the growth of corruption together with a brief look at related models this is followed by an examination of the consequences of corruption for society and the consideration of measures that might help to reduce corruption the paper ends with suggestions for future research and includes summaries of data sources and key variables for use in this research

central bank independence and public debt policy the various proposals for the institutional design of the european monetary union have drawn fresh attention to the link between monetary and public debt policies this paper explores the strategic interaction between fiscal authorities setting public debt and the central bank controlling monetary policy in the absence of political distortions an optimally designed conservative independent central bank is sufficient to establish the second best in the presence of political distortions or with coordination of monetary and fiscal policy however also a debt target is needed

exchange rates financial innovation and divisia money the sterling dollar rate 1972 1990 in this paper we examine the usefulness of divisia money relative to simple sum money for exchange rate modelling in a period of rapid financial deregulation this comparison is conducted using as a convenient framework the monetary model of the exchange rate we demonstrate inter alia that for the sterling us dollar exchange rate over the period 1972 q1 to 1990 q2 that the use of divisia money makes a significant difference to both the long and short run modelling of the exchange rate

who wants an independent central bank monetary policy making and politics the costs and benefits of cooperative monetary and fiscal policy are analysed in the framework of a partisan business cycles model it is shown that political parties with different ideologies prefer to choose different arrangements for macroeconomic policy making more specifically right wing parties favour independent central banks more than left wing parties an independent central bank is also the generally preferred option from a social welfare point of view in addition the form of policy making arrangements between the fiscal and monetary authorities is shown to influence the extent of partisan cycles

analyst forecasting errors and their implications for security analysis a comparison of 66 100 consensus estimates of wall street analysts with reported earnings for a large sample of nyse amex and otc companies demonstrates that their forecasts differ significantly from actual reported earnings a minority of estimates fall within a range around reported earnings considered acceptable to many professional investors the error rates are not meaningfully affected by the business cycle or industry groupings the average error also appears to be increasing over time these findings question the use of finely calibrated earnings forecasts that are integral to the most common valuation models and indirectly question the valuation methods themselves

which road leads to stable money demand this paper denies that the demand for money function is any more unstable than other demand functions and maintains that the controversies regarding unstable money demand are produce by poor methodology that is not shared by other areas of the field of economics when investigating demand function properties this abstract was borrowed from another version of this item

investors reactions to management earnings guidance the joint effect of investment position news valence and guidance form we report the results of an experiment that shows that investors earnings and investment related judgments are jointly influenced by their investment position long versus short the news valence of guidance issued by management and the amount of ambiguity in the guidance prior research indicates that guidance form point versus range has no effect on investors earnings estimates made in reaction to management guidance we extend this research by showing that guidance form matters conditional on investment position and news valence similarly prior research indicates that investors who hold long short positions in a stock are more optimistic pessimistic about the company s prospects we extend this research by showing that the effect of investment position documented in prior studies is conditional on news valence and guidance form we contribute to prior literature on the effects of investment position and guidance form by delineating boundary conditions for each of these effects

the disposition effect and investor experience we examine whether investing experience can dampen the disposition effect that is the fact that investors seem to hold on to their losing stocks to a greater extent than they hold on to their winning stocks to do so we devise a computer program that simulates the stock market we use the program in an experiment with two groups of subjects namely experienced investors and undergraduate students the inexperienced investors as a control procedure we consider random trade decisions made by robot subjects we find that though both human subjects show the disposition effect the more experienced investors are less affected

an alternative monetary policy target for most of the period since the mid 1970s the federal reserve has expressed its monetary policy intentions by announcing the target growth rates of three principal monetary aggregates the simple sum m1 m2 and m3 however the sweeping changes and the deregulation in the financial industry have greatly affected the relevance of these traditional monetary aggregates the unusual behaviour of the simple sum monetary aggregates has forced the federal reserve to stop setting target range for m1 the measuring of monetary aggregates has become a controversial question this paper constructs the new benchmark divisia monetary indexes which reflect moneyness more accurately than the old divisia indexes i demonstrate that the historical trends of the divisia monetary indexes are sensitive to the brenchmark rates chosen in constructing these indexes in addition i compare the forecasting performance of the new benchmark divisia monetary indexes with the simple sum and the old divisia monetary indexes in the

fiscal decentralization central bank independence and inflation abstract we develop earlier cross sectional studies of inflation rates by adding the degree of tax centralization as another explanatory variable this makes central bank independence perform appreciably better as an explanatory variable also we find that centralized countries have higher inflation

new concepts of aggregated money the federal reserve board s recent redefinition of its monetary aggregates followed three years of intensive board staff research on monetary aggregation while the new aggregates ultimately were selected along conventional lines some of the staff s research was oriented towards more fundamental changes in monetary aggregation methods this paper reviews such proposals which are based upon the rigorous application of index number and aggregation theory and of principal components analysis in the construction of economic monetary aggregates the usefulness of aggregation and index number theory in acquiring price indices is widely known the theory of the true cost of living index is an application of aggregation theory examples of applied index number theory include the commerce department s implicit price deflator which is a paasche index and the labor department s consumer price index which is a laspeyres index somewhat less well known is the fact that dual to the theory of economic price aggregates and indices is a theory of economic quantity aggregates and indices an example of a highly reputable quantity index is the divisia quantity index the monetary aggregates traditionally are thought to measure the supplied quantity of an economic good called money whenever monetary aggregates are used in the context of economic theory rather than as simple accounting identities the theory of economic quantity aggregation is specifically applicable however published monetary aggregates in all countries have always been computed as simple sums but as fisher 1922 p 29 observed in the conclusion to his classic treatise on index number theory the simple arithmetic average produces one of the very worst of index numbers and if this book has no other effect than to lead to the total abandonment of the simple arithmetic type of index number it will have served a useful purpose with an example of the simple sum index fisher 1922 p 363 found that the bias alone reaches 36 percent although index number theory has not yet found its way into the monetary theory literature all of the literature on index number theory and aggregation theory for the past half century supports the result long ago deduced by fisher 1922 p 361 that the simple arithmetic index should not be used the views expressed herein are solely those of the authors and do not necessarily represent the views of the board of governors of the federal reserve system this research was partially supported by national science foundation grant soc 76 84459 we are deeply indebted to the conference session s discussant of this paper w erwin diewert for volunteering to cede his allocated journal space to us so that the paper could take its current extended form federal reserve board washington d c

shrinking money the demand for money and the nonneutrality of money abstract we evaluate the macroeconomic implications of post world war ii money demand changes in two business cycle models the limited participation model and the sticky price model the sticky price model is invariant to changes in money demands however the limited participation model predicts the effect of a money shock on output rose by 100 percent between 1952 and 1980 and subsequently fell 65 percent this prediction is hard to reconcile with evidence that suggests the effects of monetary shocks are stable over time and suggests that goods market imperfections rather than asset market imperfections may be the driving force behind postwar u s monetary nonneutrality

cointegration and structural change an application to the u s demand for money wankeun oh i perform the cointegration tests for the trivariate model of real monetary aggregates real personal income and short term interest rate i find the existence of a long run relationship among these three variables to check the stability of a long run money demand relationship i implement a rank constancy test and cusum test the test results show that real mi is relatively more stable than other aggregates but structural change occurred during the 1970s and early 1980s this is consistent with prior research on money demand jel e41 i introduction incorporating structural change when performing tests on the properties of stochastic processes is important because structural breaks may cause misspecification problems most tests of structural change consider the stability of the parameters over time tests for structural breaks and parameter stability have been studied extensively a partial list includes chow 1966 brown et al 1975 harvey and collier 1977 king 1987 ploberger et al 1989 in the context of unit root processes perron 1989 showed that the presence of a one time change in the level or slope of the trend function can severely distort the results of unit root tests and it is natural to ask how structural change can distort the results of cointegration tests 1 traditional tests of parameter stability ask if the parameters of the model are constant in contrast quintos 1993 proposed a test for stability of the long run relationship s in a cointegrating regression the test is based on johansen s 1988 framework and the test statistic is simply the weighted sum of the likelihood ratio test as given in johansen 1988 quintos s rank test is very different from the traditional cusum and chow tests for parameter stability because her rank test checks for stability of the cointegrating relationship between variables in other words the rank test checks whether cointegration holds for the full period the traditional cusum and chow tests assume that cointegration holds for the full period or does not hold for the full period and tests simply whether the cointegration vector changes for example if there is cointegration from 1960 1990 between revenues and expenditures with cointegrating vector 1 1 then the cusum and chow tests check whether the cointegra ting vector 1 1 is stable throughout the period the rank constancy test checks whether the cointegration rank is stable throughout the period not whether the cointegrating vector is stable at 1 1 in other words the rank test will check whether for example there is cointegration from 1960 1980 and no cointegration from 1980 onward the chow and cusum tests are not designed to check for this the structural stability of money demand relationships has been the issue of a substantial number of empirical studies 2 in general structural stability means stability of the underlying behavioral equations 3 this term includes parameter stability and stability of functional form friedman s 1990 research on the money demand function assumes that a long run equilibrium relationship exists between real money balances real income or real wealth and the opportunity cost of holding real money balances recently there has been strong evidence of cointegration between real income real money balances and a nominal interest rate for instance engle and granger 1987 dickey et al 1991 hafer and jansen 1991 hoffman and rasche 1991 mehra 1993 miller 1991 fischer and nicoletti 1993 and baba et al 1992 report on cointegration among variables in u s aggregate money demand jain and moon 1994 report on cointegration in u s sectoral money demand yashiv 1994 and engsted 1993 on money demand in a high inflation country and hoffman et al 1995 report on international money demand comparison this article asks if long run money demand relationship is stable and if so for which measure of money is it stable over time

the choice among monetary aggregates as targets and guides for monetary policy difficulties in meeting its monetary targets led the federal reserve in october 1979 to adopt a new operating procedure to achieve firmer control over monetary aggregates yet the inflationary environment has fostered financial developments that affect the behavior of the traditional monetary aggregates and that raise questions whether different aggregates may not be better this paper compares the various monetary aggregates for their usefulness as guides for monetary policy in the light of recent financial developments the criterion of usefulness is the ability to influence and predict gnp growth this ability is tested in two ways first by the stability of the velocities of the monetary aggregates and second by the advance information they provide of gnp growth it is presumed that the aggregates with the most stable velocities make the best targets for monetray policy and that those containing the most advance information make the best guides for policy the paper has three main sections the first discusses the criteria for using monetary aggregates as targets and guides the second two sections describe and report tests of the various monetary aggregates as targets and guides a summary of findings is presented as a final section

the effect of central bank independence on inflation in developing countries abstract ismihan and ozkan ismihan m ozkan f g 2004 does central bank independence lower inflation economics letters 84 305 309 provide theoretical support for prior studies empirical findings of positive or no significant relationship between central bank independence cbi and average inflation performance the present paper argues that these findings are spurious because the studies use an econometric methodology that does not account for the measurement error in their proxies for cbi this paper employs an econometric methodology that does account for this measurement error and finds a strong negative relationship between cbi and inflation even though the sample is limited to developing countries

tests of different monetary aggregates for the monetary models of the exchange rate in five asean countries this study examines the usefulness of divisia money relative to simple sum money for exchange rate modelling in a period of rapid financial deregulation this comparison is conducted using the monetary model of the exchange rate in the long run modelling the divisia money is significantly superior to simple sum money in the case of malaysia and the philippines while indifferent for indonesia singapore and thailand

endogenous overconfidence in managerial forecasts abstract we examine whether attribution bias leads managers who have experienced short term forecasting success to become overconfident in their ability to forecast future earnings importantly this form of overconfidence is endogenous and dynamic we also examine the effect of this cognitive bias on the managerial credibility consistent with the existence of dynamic overconfidence managers who have predicted earnings accurately in the previous four quarters are less accurate in their subsequent earnings predictions these managers also display greater divergence from the analyst consensus and are more precise lastly investors and analysts react less strongly to forecasts issued by overconfident managers

microfoundations for a stable demand for money function scientific revolutions seldom occur when the prevailing theories appear to be performing well it is only when the accepted theory fails to offer a satisfactory explanation of events that new and more robust theories are proposed of these new theories the one which can explain the successful performance of the previous theory and also the events which led to its demise becomes the replacement so it is in the history of modern monetary economics the failure of the partial adjustment model in the mid s is well documented in the united kingdom and the united states and the search for a replacement has been the main point on the agenda since that time there are many contending theories some of which are advocated by the other contributors to this controversy but the mark of a truly better theory which can be claimed to supersede the partial adjustment model is one that can explain the success and the breakdown of the previous theory as well as the events subsequently central to the argument of this paper is the importance of individual behaviour in the context of a market for monetary assets only by means of careful investigation of the microeconomic behaviour underpinning monetary economics at the individual and the market level can the stability of the money demand function be restored it is the purpose of this paper to suggest that the buffer stock approach has gone further than other approaches in dealing with the fundamental micro foundations of the demand for money it does not suggest that other approaches have no microfoundations but they tend to concentrate exclusively on specific aspects of the micro structure such as separability and ignore others relating to the behaviour of individual optimisers in a monetary market the buffer stock model has firm micro foundations which can explain the events both before and after the breakdown of the partial adjustment model section i provides an historical background to the debate and section ii gives a brief overview of buffer stock models which shows that unlike other approaches they have been able to reconcile the past success of the partial adjustment model with its present failure the nature of the microfoundations of buffer stock models are the source of the success and are discussed in more detail in section iii the final section evaluates the buffer stock approach in the light of the other alternatives

the own price of money and a new channel of monetary transmission traditionally the effects of monetary policy actions on output are thought to be transmitted via monetary or credit channels real business cycle theory by contrast highlights the role of real price changes as a source of revisions in spending and production decisions motivated by the desire to focus on the effects of price changes in the monetary transmission mechanism this paper incorporates a direct measure of the real own price of money into an estimated vector autoregression and a calibrated real business cycle model consistent with the rbc view of the monetary transmission mechanism both approaches reveal that movements in the own price of money are strongly related to movements in output

the new monetary aggregates comment in a recent paper published in this journal berkman 10 disputed the usefulness of the new chained tornquist theil divisia quantity indexes of the economy s flow of monetary services which just have begun to become available within the federal reserve system l while a few of his comments have some merit his criticisms are largely based upon a faulty understanding of aggregation theory and he thereby fails to see the forest for the trees

central bank independence and macroeconomic performance some comparative evidence this note uses information on a sample of sixteen oecd countries to assess the relationship between central bank independence and macroeconomic performance as previous work suggests politically controlled central banks are more likely to pursue policies that lead to high and variable inflation however the authors find little evidence that political control of central bank policy has any impact on measures of the level or variability of growth unemployment or the ex ante real interest rate copyright 1993 by ohio state university press

differential interpretation of public signals and trade in speculative markets most models of trade in speculative markets assume that agents interpret public information identically we provide empirical evidence on the relation between the volume of trade and stock returns around public announcements and we argue that the evidence is inconsistent with this assumption we then develop a model of trade around public announcements that incorporates differential interpretations and is consistent with the observed volume return relation then we test the standard model of belief revision underlying most models of trade using stock brokerage research analysts earnings forecasts the hypthesis of identical interpretations seems inconsistent with the forecast revisions in these data

the empirical reliability of monetary aggregates as indicators 1983 1987 the empirical reliability of monetary aggregates as indicators 1983 1987 i introduction it is widely believed that monetary aggregates have failed to predict real growth and inflation over 1983 87 this presumed breakdown of previously reliable linkages between money growth and future output and inflation has been variously attributed by the present authors among others to changes in money demand induced by regulatory change and to parameter instability due to structural change this paper observes that these disputations may be moot since the traditional definition of money currency plus demand deposits shows no evidence of structural change and yields nearly as low or lower prrediction root mean square errors for both real gnp growth and inflation over 1983 87q2 than the standard errors of estimate obtained for 1961 82 part of the so called breakdown in the monetary indicators especially in the case of m1 may be explained by the fact that current m1 or m1b is defined much like the old m2 and current m1a is defined much like old m1 thus it is probably not too surprising that use of m1 as a monetary indicator does not yield consistent predictive power over a period of time in which it experienced redefinition if there is a mystery in the 1980 it is not why m1a has done so well but why economists abandoned it for broader m1b currency demand deposits and other checkable deposits or ocds 1 with the nationwide introduction of negotiable order of withdrawal now accounts on january 1 1981 m1a fell by 5 5 percent a 22 1 percent per annum rate in the first quarter while m1b rose at a 3 1 percent per annum rate at the time the federal reserve system expected m1a demand to shift down as households chose to substitute from demand deposits to the newly available in most states ocds accordingly the sharp drop in m1a was expected to be reflected in a once for all upward shift in its velocity with no effect on nominal income or its components 2 however consistent with the shock absorber view of money demand even if the long run demand for m1a was unchanged a sharp decrease in its quantity would induce an equal contemporaneous increase in its velocity 3 contrary to the federal reserve s expectation the shock absorber view would thus predict that the actual value of velocity would temporarily exceed its long run equilibrium level so that nominal income would tend to fall or grow less rapidly as m1a velocity adjusted to the money shock figure 1 shows that compared to a relatively small drop in m1 velocity the contemporaneous velocity of m1a moved sharply in the first quarter of 1984 4 the shock absorber hypothesis suggests that contemporaneous velocity movements would be dominated by money supply shocks and thus attributes the different movements of m1a and m1 velocity to differences in magnitude and signs of the shocks in m1a and m1 what milton friedman 1983 calls leading velocity is a crude way of allowing nominal gnp to adjust to past money shocks panels a and b in figure 2 illustrate leading velocity for lags between money and gnp of one and four quarters respectively the longer the adjustment lag the more leading velocity becomes a smooth trend dominated series for m1a 5 however m1b continues to display a sizeable break from its historical pattern this observation suggests that the recent behavior of the economy may be consistent with that indicated by movements in m1a and that the choice to switch to m1b as the standard definition of the narrow money supply was unfortunate and a major source of recent forecasting failure 6 this paper runs a race among m1a m1 and m2 by comparing out of sample forecasting performance and tests of structural stability 7 an explanation is also offered for the observed departure of m1 velocity from its historical trend based on a large battery of conventional tests the results are remarkably favorable to the continued reliability of m1a as a useful indicator of future economic performance and for its relevance as a tool in monetary policy

fractional monetary dynamics we test for fractional dynamics in us monetary series their various formulations and components and velocity series using the spectral regression method we find evidence of a fractional exponent in the differencing process of the monetary series both simple sum and divisia indices in their components with the exception of demand deposits savings deposits overnight repurchase agreements and term repurchase agreements and the monetary base and money multipliers no evidence of fractional behaviour is found in the velocity series granger s journal of econometrics 25 1980 aggregation hypothesis is evaluated and implications of the presence of fractional monetary dynamics are drawn

pre announcement and event period private information abstract pre announcement information is private information gathered in anticipation of a public disclosure event period information is private information useful in conjunction with the announcement itself typically rational models of trade are based exclusively on one type of information such models are less descriptive of real market settings and misspecified empirically therefore we introduce a model of rational trade with both features and discuss its implications

does central bank independence lower inflation this paper provides a potential explanation for the recent findings of no significant relationship between central bank independence cbi and lower inflation we argue that although cbi delivers lower inflation in the short term it may reduce the scope for productivity enhancing public investment and so harm future growth potential we also argue that the effects on growth make cbi less likely to achieve lower inflation in the long term

a reexamination of analysts earnings forecasts for takeover targets abstract we examine analysts earnings forecasts for a sample of takeover targets and document that the announcement month forecasts are systematically revised upward supporting the hypothesis that a takeover announcement conveys favorable information about the target firm in addition we find that abnormal forecast revisions of future stand alone earnings are significantly greater for targets with low tobin s q ratios relative to targets with high q ratios lending further support to the information hypothesis finally we provide evidence that managerial resistance to the takeover does not destroy value our results are in direct contrast to pound 1988

measures of money and the monetary model of the canadian us dollar exchange rate abstract although the measurement of money is central to an empirical monetary modelof exchange rates existing empirical studies rely on official aggregates as a measure of money this paper uses superlative monetary aggregates in the context of a monetary model to explain the exchange rate between canada and the united states the parameters of the model are estimated using two stage least squares with quarterly data for the period 1972 1985 the paper applies davidson mackinnon tests to establish whether superlative and official monetary aggregates areobservationally equivalent in a monetary model of the canadian u s dollar exchange rate

competitive interest payments on bank deposits and the long run demand for money reply this paper tests two assumptions made in previous demand for money studies the first assumption concerns the role assigned to the interest rate in the demand for money function common practice identifies the rate of interest with the opportunity cost of holding money in section i this formulation is shown to blur an important distinction between the price of money and the price of money substitutes and to implicitly assume that the relevant price variable is the difference between these two distinct prices a second assumption is that the current ban on interest payments on demand deposits is fully effective in section ii i operationally define these price variables and estimate perfectly competitive interest payments on commercial bank deposits this is done by crudely measuring commercial bank marginal costs and assuming that all excess profit is passed on to depositors in indirect ways section iii presents estimates of a more complete longrun demand for money relationship which explicitly includes an own price and a cross price as separate influences and assumes that the prohibition of the payment of interest on deposits is totally ineffective although no firm conclusion is reached concerning the proper functional specification of the demand function the results significantly improve upon previous demand for money estimates which assumed that the interest payment prohibition is totally effective in section iv the results are summarized and implications of the analysis for monetary theory are presented my competitive demand for money formulation leads to a reinterpretation of the existing evidence on what is generally referred to as the interest elasticity of demand for money this estimate is shown to be significantly biased downward it also implies that the demand for and supply of money are more interdependent than is usually assumed

the translog utility function and the demand for money in the united states in recent years considerable effort has been directed towards establishing the nature of the relationship between money and nearmonies but with mixed success the approaches vary from multi interest rate single equation studies to the careful simultaneous equations studies summarized and amended by feige and pearce 1977 and extended recently by donovan 1978 offenbacher 1979 and barnett 1980 the empirical results also vary with numerous studies favoring only one interest rate see the surveys in fisher 1978 1983 some claiming that a variety of entities are close substitutes for money e g chetty 1969 and others showing that weak substitution or even complementarity may be the result of the measurement of elasticities of substitution between money and a number of other assets e g feige and pearce 1977 offenbacher 1979 and barnett 1980 the debate seems to have overshadowed a second and equally intriguing issue which centers on the establishment of an acceptable definition of money the basic idea of this study is to take an approach that takes account of the different degrees of moneyness possessed by the various monetary assets this paper produces quantitative estimates of the degree of substitutability of other monetary assets for money in the context of a flexible functional form model with a

currency substitution and economic monetary aggregates abstract existing analyses of currency substitution rely on the assumption that domestic monetary assets are perfect substitutes for each other the present paper examines empirically the currency substitution hypothesis using divisia monetary aggregates which relax the perfect substitutability assumption used in earlier work the empirical results support the hypothesis of currency substitution for the united states

financial analysts forecasts of earnings a better surrogate for market expectations abstract the specification of the market expectation of accounting numbers is a common feature of many empirical studies in accounting and finance givoly and lakonishok 1979 found that financial analysts forecasts have information content this study evaluates the quality of analysts forecasts as surrogates for the market expectation of earnings and compares it with that of prediction models commonly used in research results indicate that prediction errors of analysts are more closely associated with security price movements suggesting that analysts forecasts provide a better surrogate for market expectations than forecasts generated by time series models the study also identifies factors that might contribute to the performance of the financial analysts forecasts the broadness of the information set employed by analysts and to a lesser extent their reliance on information released after the end of the fiscal year appear to be important contributors to their performance

the disposition effect in securities trading an experimental analysis the disposition effect is the tendency to sell assets that have gained value winners and keep assets that have lost value losers disposition effects can be explained by the two features of prospect theory the idea that people value gains and losses relative to a reference point the initial purchase price of shares and the tendency to seek risk when faced with possible losses and avoid risk when a certain gain is possible our experiments were designed to see if subjects would exhibit disposition effects subjects bought and sold shares in six risky assets asset prices fluctuated in each period contrary to bayesian optimization subjects did tend to sell winners and keep losers when the shares were automatically sold after each period the disposition effect was greatly reduced

inefficiency in analysts earnings forecasts systematic misreaction or systematic optimism a rational analysis of analyst behavior predicts that analysts immediately and without bias incorporate information into their forecasts several studies document analysts tendency to systematically underreact to information underreaction is inconsistent with rationality other studies indicate that analysts systematically overreact to new information or that they are systematically optimistic this study discriminates between these three hypotheses by examining the interaction between the nature of information and the type of reaction by analysts the evidence indicates that analysts underreact to negative information but overreact to positive information these results are consistent with systematic optimism in response to information the literature on financial analysts defines the phrase forecast inefficiency to mean forecasts that fail to accurately incorporate new information on a timely basis and or that are biased these forecasts have also been described as irrational or suboptimal prior studies report inefficiency in analysts forecasts finding that they are upwardly biased and inaccurately reflect available information some studies conclude from this that analysts underreact to information other studies conclude that analysts overreact if markets treat analysts forecasts as both rational and statistically optimal then inefficient forecasts could have important implications for the efficiency of pricing in securities markets in this paper we reexamine the apparent tendency of analysts to misinterpret earnings information the intent of this study is to discriminate between three hypotheses 1 that analysts systematically underreact to new earnings information 2 that analysts systematically overreact to new earnings information and 3 that analysts are systematically optimistic in their reactions for hypotheses 1 and 2 the direction of the misinterpretation i e underor overreaction is independent of the nature of the information received in contrast hypothesis 3 predicts that analysts are optimistic in interpreting

measuring the average marginal tax rate from the individual income tax the economic effects of taxation depend on the configuration of marginal tax rates we consider here the appropriate measure of a marginal tax rate for the federal individual income tax which has a graduated rate structure and allows for numerous legal and illegal deductions from total income our conclusion is that the explicit marginal rate from the tax schedule is the right concept for many purposes hence we construct approximately weighted averages of these marginal tax rates for 1916 80 when weighted by adjusted gross income the arithmetic average of marginal tax rates is 5 in 1920 2 in 1930 6 in 1940 20 in 1950 23 in 1960 24 in 1970 and 30 in 1980 we also discuss the dispersion of marginal tax rates as well as the behavior of average tax rates and deductions from taxable income one noteworthy result concerns the fraction of adjusted gross income that accrues to families that face a marginal tax rate of at least 35 this fraction quadruples from 1964 to 1980 this abstract was borrowed from another version of this item

contagion of wishful thinking in markets prior research provides only weak and controversial evidence that people overestimate the likelihood of desirable events wishful thinking but strong evidence that people bet more heavily on those events wishful betting two experiments show that wishful betting contaminates beliefs in laboratory financial markets because wishful betters appear to possess more favorable information than they actually do as a consequence market interaction exacerbates rather than mitigates wishful thinking this phenomenon contagion of wishful thinking could be problematic in many settings where people infer others beliefs from their behavior

sweep programs and optimal monetary aggregation abstract this paper examines the admissibility of monetary aggregate groupings for the us over 1993 2001 based upon weak separability we investigate the impact of retail and commercial demand deposit sweep programs on the separability of monetary asset groupings weak separability is tested using the swofford whitney and fleissig whitney tests we use varian s measurement error adjustment procedure to eliminate violations of the generalized axiom of revealed preference garp when funds from both retail and commercial demand deposit sweep programs are placed within checkable deposits all groupings narrow and broad pass garp and weak separability for groupings based on conventional money measures tests tend to favor broad aggregates

relative prices in the uk personal sector money demand function nonparametric demand analysis is used in order to establish admissible monetary aggregates and also to establish a potential role for relative prices in the money demand function a conventional money demand specification is then contrasted with a money demand function which contains the relative prices of durables nondurables and services as additional regressors evidence from long run cointegration analysis short run error correction models and nonnested testing all confirm a role for relative prices in the u k personal sector s money demand function copyright 1996 by royal economic society

a new empirically weighted monetary aggregate for the united states i introduction this article uses an approach to long run econometric modeling proposed by pesaran et al 2001 hereafter pss to develop an empirically weighted broad monetary aggregate for the united states and to demonstrate the advantages of this type of aggregate from a monetary policy perspective in particular we examine the ability of this type of approach to deal with periods of significant financial innovation and money demand instability a key requirement for monetary aggregates to provide a useful role in guiding monetary policy is that they should be stably related to the objectives of policy such as inflation or nominal income growth in this context the united states has exhibited periodic evidence of significant money demand instability most notably these have been goldfeld s 1976 case of the missing m1 in 1973 74 and the missing m2 episode of the early 1990s feldstein and stock 1996 in both cases the aggregate in question experienced a significant velocity increase and as a consequence previously established and apparently stable money demand relationships began to seriously overpredict the growth in these aggregates the missing m1 episode in 1973 74 together with subsequent evidence that m2 was more predictable than m1 led many economists to use m2 as an indicator of nominal activity hence during the 1980s m2 became the primary intermediate target of monetary policy furthermore the primacy of m2 appeared to be well supported by the available empirical evidence feldstein and stock 1994 for example established that the rate of change of m2 was a statistically significant predictor of the rate of change of nominal gross domestic product gdp over the period 1959 92 furthermore m2 remained statistically significant when short term interest rates were added to the relationship subsequent research such as miyao 1996 and estrella and mishkin 1997 however cast doubt on the robustness of this result carlson et al 2000 p 34 for example summarize the current situation by arguing that the promising empirical conclusions of feldstein and stock 1994 that established predictive content for m2 in a vector error correction setting do not seem to find support in data that extend through the mid 1990s the key factor behind the breakdown in the m2 relation appears to have been the substitution away from time deposits and into mutual funds particularly stock and bond mutual funds in the low interest rate environment of the early 1990s although the definition of m2 has been expanded by the federal reserve in the past to include money market mutual funds mmmfs and money market deposit accounts mmdas for example a number of analysts duca 1995 darin and hetzel 1994 orphanides et al 1994 have advocated that m2 should be expanded further to include these stock and bond mutual funds m2 significantly these studies typically use the simple sum aggregation approach in which all component assets are given equal and constant weights over time this approach does not seem consistent however with the accumulating evidence of a significant shift in wealth holders preferences sometime in the early 1990s carlson et al 2000 for example add to the empirical evidence that had accumulated during the 1990s by suggesting that the instability was associated with a permanent upward shift in m2 velocity between 1990 and 1994 furthermore they argue that our results support the hypothesis that households permanently reallocated a portion of their wealth from time deposits to mutual funds p 381 clearly simple sum aggregation is not able to take account of these changes in preferences more significantly however simple sum aggregation cannot take account of any changes in the relationship between component assets and nominal income over time although carlson et al 2000 do manage to reestablish a stable money demand relationship for the mzm money at zero maturity and m2m m2 minus small time deposits aggregates through the 1990s this is only possible by specifically accounting for the financial innovation that occurred in the early 1990s
