bounded price variation and rational expectations in endogenous switching model of the u s corn market a model that includes bounded price variation and rational expectations by producers is estimated for the u s corn market the resulting model specification is highly nonlinear though since the probability of market equilibrium must be determined endogenously unlike previous research the cross equation restrictions implied by the rational expectations hypothesis are incorporated in the bounded prices model by using fair and taylor s 1983 procedure for obtaining maximum likelihood estimates of nonlinear rational expectations models the resulting model is compared against a standard equilibrium model with naive expectations the results show the bounded prices model is a superior specification copyright 1989 by mit press

optimal discretionary monetary policy in a model of asymmetric central bank preferences this paper considers optimal monetary policy in the context of the central bank adopting an asymmetric objective function our results show that under asymmetric preferences many of the extant results on the time consistency problem need no longer hold

testing for the absence of expected real profits from forward market speculation abstract this paper tests for the absence of expected real profits from forward market speculation it contrasts with the literature that has considered opportunities for expected nominal profit from speculation that is profits denominated in one of the currencies these studies assume money illusion on the part of market participants but this paper does not empirical results fail to find evidence of unexploited real profit opportunities

switching regression models with imperfect sample separation information with an application on cartel stability an exogenous switching regression model with imperfect reginme classificationi information is specified and applied to a study of cartel stability an efficient estimation method is proposed which takes this imperfect information into account the consequences of misclassification are analyzed the direction of the least squares bias is derived an optimal regime classification rule is obtained and compared theoretically and empirically with other classification rules we then examine the joint executive committee a railroad cartel in the 1880 s the econometric evidence indicates that reversions to noncooperative behavior did occur for the firms in our sample and these reversions involve a significant decrease in market price this article is concerned with the possibility of estimating a switching regression model and its application to a study on cartel stability the switching regression model is the exogenous switching model proposed by quandt 24 which generalized a problem of mixture distributions day 4 the sample in this model is generated from distinct regression equations or regimes for each time period if the investigator has a priori information on how the sample is partitioned into the underlying regimes it is a switching regression model with known sample separation otherwise it is a model with unknown sample separation estimation of these latter models has been considered by quandt 24 goldfeld and quandt 8 and kiefer 14 16 among others a switching regression model is appropriate for the study of cartel behavior when there are price wars as firms will revert from cooperative to noncooperative behavior and so the industry supply function shifts occasionally this model will allow us to exploit the fact that there will be periodic stochastic switches or reversions between cooperative and noncooperative conduct in order to identify collusive episodes

uncovering financial market expectations of inflation this paper seeks to uncover market expectations of inflation from the joint dynamics of nominal interest rates and observed inflation i postulate 1 the existence of a stable vector autoregression in unobserved variables and 2 efficient financial markets the estimation procedure requires no further structural assumptions the econometrician need not observe all the information used by agents in forming forecasts or all the variables that influence real interest rates i find no empirical evidence that economic recessions are correlated with inflation forecast errors however postwar recessions are associated with ex ante real interest rates that are twice the postwar average

monetary policy regimes and the reduced form for interest rates this study investigates whether the recent poor performance and inst ability of reduced form interest rate equations can be accounted for by changes in monetary policy regimes the results imply that reduced form coefficients move by statistically significant and economically meaningful amounts in response to such policy parameter shifts both in sample and out of sample predictions from the models that allow f or the endogeneity of the money stock outperform those produced by the conventional specification copyright 1987 by ohio state university press

the federal reserve s new operating procedures a post mortem abstract although money stock targeting has been the strategic focus of federal reserve policy since the mid 1970 s operating policy the tactics whereby the longer run strategy is implemented over short term intervals has been changed by the federal reserve at least twice over this period a particularly dramatic change in operating policy was announced by the federal reserve in october 1979 this paper provides empirical evidence that settles questions about the nature of this change and suggests that the new operating procedures may have contributed to the heightened interest rate volatility experienced over the 1979 to 1982 period

internal and external habits and news driven business cycles in many applications of habit persistence to macroeconomics it is of little significance whether habits are internal or external in this paper it is shown that the distinction between internal and external habits is important in a situation wherein a shock is news about the future an internal habit can be a source of news driven business cycles positive comovement in consumption labor investment and output from the news about the future whereas an external habit cannot

a simple account of the behavior of long term interest rates recent empirical research on the term structure of interest rates has shown that the long term interest rate is well described by a distributed lag on short term interest rates but does not conform to the expectations theory of the term structure it has been suggested that the long rate overreacts to the short rate this paper presents aunified taxonomy of risk premia or deviations from the expectations theory this enables the hypothesis of overreaction to be formally stated it is shown that if anything the long rate has underreacted to the short rate however the independent movement of the long rate is primarily responsible for the failure of the expectations theory

government expenditure and the dynamics of high inflation abstract this paper develops a dynamic model of inflation where the money supply is determined by the government s use of newly created money to finance its budget deficit in turn the government s deficit is influenced by past inflation rates that reduce the real value of tax receipts while the money supply and the budget deficit are modeled as endogenous government expenditure is assumed to be exogenously determined by the policymaker changes in fiscal policy are allowed by modeling expenditure as an autoregressive process subject to discrete switches in regime agents are conjectured to have access to a larger set of information than the researcher this additional information is incorporated in the rate of inflation through the agents money demand decision the econometrician constructs probability assessments concerning the regime of the spending process at every point in time and refine his her inferences by exploiting the structural relationship between inflation money growth and government expenditure

inflation targeting under asymmetric preferences this paper develops and estimates a game theoretical model of inflation targeting where the central banker s preferences are asymmetric around the targeted rate specifically positive deviations from the target can be weighted more or less severely than negative ones in the central banker s loss function it is shown that some of the previous results derived under the assumption of symmetry are not robust to this generalization of preferences estimates of the central banker s preference parameters for canada sweden and the uk are statistically different from the one implied by the commonly used quadratic loss function

bias in federal reserve inflation forecasts is the federal reserve irrational or just cautious abstract inflation forecasts of the federal reserve seem to have systematically under predicted inflation from the fourth quarter of 1968 until volcker s appointment as chairman and to systematically over predict it afterwards until the second quarter of 1998 furthermore under quadratic loss commercial forecasts seem to have information not contained in those forecasts to investigate the cause of this apparent irrationality this paper recovers the loss function implied by federal reserve s inflation forecasts the results suggest that the cost of having inflation above an implicit time varying target was larger than the cost of having inflation below it for the period since volcker and that the opposite was true for the pre volcker era once these asymmetries are taken into account the federal reserve s inflation forecasts are found to be rational

high and volatile real interest rates where does the fed fit in the federal reserve s new procedures for the conduct of monetary policy introduced on october 6 1979 have been the subject not only of considerable academic and political interest but also of intense debate b friedman 1982 roley 1982 walsh 1982 1984 mascaro and meltzer 1983 among others the fed s new operating procedures generally are perceived to have resulted in abnormally high and volatile real interest rates and thus to have contributed to if not been totally responsible for the deepest recession in postwar history in this paper we address the following question was the advent of the increased volatility and level of the real rate of interest concurrent with the fed s october 1979 change in operating procedures that is was the real rate of interest high and more volatile immediately after the october 1979 change in policy procedures in which case we might infer a connection between the fed s change in policy procedures and the increased volatility and level of the real rate or did the real rate become high and more volatile some time following the policy change which might lead us to conclude that the increased volatility and the increased level of the real rate was connected to some other event s occurring after the october 1979 policy change

the price consumption puzzle of currency pegs abstract a defining stylized fact associated with exchange rate based stabilization programs is that their initial phase is characterized by several years of continuous expansion in private consumption and a gradual appreciation of the real exchange rate this paper shows that a large class of standard optimizing models is unable to account for this empirical regularity in particular models in this class predict that a gradual appreciation of the real exchange rate must necessarily be accompanied by a declining path of consumption the paper suggests several possible solutions to this problem and develops one in detail namely the relaxation of the assumption of time separability in preferences specifically it shows that under habit formation currency pegs induce a positive comovement between consumption and the real exchange rate the paper also establishes that habit formation provides an explanation for why in failed currency pegs a contraction in aggregate demand sets in before the collapse of the program

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

canadian inflation targeting this paper examines the intellectual environment in canada that led to the adoption of inflation targets starting in 1991 reviews some of the canadian contributions to the vast literature on inflation targeting and presents evidence in support of the view that the implementation of inflation targeting in canada has been particularly successful when compared with the experiences of other inflation targeting countries and the us

fiscal news and macroeconomic volatility abstract this paper analyzes the contribution of anticipated capital and labor tax shocks to business cycle volatility in an estimated new keynesian business cycle model while fiscal policy accounts for about 15 of output variance at business cycle frequencies this mostly derives from anticipated government spending shocks tax shocks both anticipated and unanticipated contribute little to the fluctuations of real variables however anticipated capital tax shocks do explain a sizable part of inflation fluctuations accounting for up to 12 of its variance in line with earlier studies news shocks in total account for about 50 of output variance further decomposing this news effect we find permanent total factor productivity news shocks to be most important when looking at the federal level instead of total government the importance of anticipated tax and spending shocks significantly increases suggesting that fiscal policy at the subnational level typically counteracts the effects of federal fiscal policy shocks

are economic time series asymmetric over the business cycle it has long been argued that major cyclical variables such as the unemployment rate display an asymmetric behavior over various phases of the business cycle the paper provides a statistical test for this hypothesis using the framework of finite state markov processes i implement a test to see if the behavior of the unemployment rate is characterized by sudden jumps and slower drops it is argued that the framework provided in the paper can also be used to test other sample path properties of economic time series

are expectations of inflation rational or is variation of the expected real interest rate unpredictable abstract the joint hypothesis developed and tested in this paper is that the nominal interest rate is a rational expectation of the real interest rate plus the inflation rate and that variation of the expected real interest rate is unpredictable on the basis of information used in the test this test is applied to quarterly data on three month united states treasury bills of 1954 to 1973 the information used in the tests includes besides past interest rates and inflation rates past growth rates of the source base the money supply and real gnp some of the tests allow for a positive marginal tax rate which changes the results little the hypothesis is generally consistent with the data which provides support for the proposition that predictable changes of the money supply do not affect expected real interest rates over periods as short as a quarter

inflation targeting a new framework for monetary policy he world s central bankers and their staffs meet regularly in venues from basle to washington to share ideas and discuss common problems perhaps these frequent meetings help explain why changes in the tactics and strategy of monetary policymaking such as the adoption of money growth targets in the 1970s the intensification of efforts to reduce inflation in the 1980s and the recent push for increased institutional independence for central banks tend to occur in many countries more or less simultaneously whatever their source major changes in the theory and practice of central banking are of great importance for both individual countries and the international economy in this article we discuss a new strategy for monetary policy known as inflation targeting which has sparked much interest and debate among central bankers and monetary economists in recent years this approach is characterized as the name suggests by the announcement of official target ranges for the inflation rate at one or more horizons and by explicit acknowledgment that low and stable inflation is the overriding goal of monetary policy other important features of inflation targeting include increased communication with the public about the plans and objectives of the monetary policymakers and in many cases increased accountability of the central bank

rational expectations econometric analysis of changes in regime an investigation of the term structure of interest rates abstract this paper is of interest both for its methodological contribution of new tools for analyzing rational expectations models and for its substantive conclusions concerning the term structure of interest rates during the monetary experiment of october 1979 the paper studies systems subject to changes in regime interpreted here as occasional discrete shifts in the parameters governing the time series behavior of exogenous economic variables the specification is shown to be quite tractable both theoretically and empirically the technique is used to analyze yields on three month treasury bills and ten year treasury bonds during 1962 to 1987 a constant parameter linear model for short term rates is shown to be inconsistent both with the univariate time series properties of short rates and with the observed bivariate relation between long and short rates under the expectations hypothesis of the term structure an alternative nonlinear model that admits the possibility of changes in regime affords a much better description of the univariate process for short rates moreover the cross equation restrictions implied by the expectations hypothesis of the term structure are consistent with the nonlinear specification indeed the residuals of the restricted relation have a standard error of only 0 8 basis points this is a third less than that of a completely unrestricted linear regression of long rates on short rates and compares with an unconditional standard deviation of long rates of 142 basis points i conclude that once the recognition by bond traders of changes in regime is taken into account the expectations hypothesis of the term structure of interest rates holds up fairly well for these data

credibility and changes in policy regime this paper addresses the issue of credibility from an econometric perspective it develops a rational expectations model of inflation in which the dynamics are driven by the level of government spending and by the effect of past inflation rates on the value of real taxes government expenditure is modeled as an exogenous autoregressive process subject to discrete changes in regime the regimes are defined by whether the level of spending is or is not consistent with the rate of inflation targeted by the government as part of a stabilization program in making their money demand decision the agents need to construct probability inferences regarding the state of the expenditure process credibility is quantified by the agents inferred probability that the joint observation of inflation the nominal interest rate and government spending is generated by the reformed expenditure regime in an application to israel results indicate that the failed stabilization program of november 1984 was less than fully c

fiscal dependence on trade taxes and economic development additional results and a reconciliation of the empirical evidence using brazilian data spanning the period 1910 75 new evidence is presented on the hypothesis that a country s fiscal dependence on trade taxes is inversely related to her level of economic development at least once the latter passes a certain threshold unlike previous studies this study uses methods which highlight the dynamic and temporal nature of the underlying relationships the results indicate strong support for the hypothesis and also suggest that the conflicting time serious evidence can be reconciled

uncovering financial markets beliefs about inflation targets this paper exploits the term structure of interest rates to develop testable economic restrictions on the joint process of long term interest rates and inflation when the latter is subject to a targeting policy by the central bank in an empirical application to the canadian inflation target zone results indicate that financial markets perceive the band to be of approximately the same width as announced but asymmetrically distributed around the official target this finding suggests that in practice the monetary authority might attach different weights to positive and negative inflation deviations from the target copyright 2000 john wiley sons ltd

news about aggregate demand and the business cycle abstract the plausibility of expectations driven cyclical fluctuations in an otherwise standard one sector real business cycle model with variable capital utilization and mild increasing returns to scale in production is examined due to a dominating wealth effect our model is able to generate qualitatively as well as quantitatively realistic aggregate fluctuations driven by news impulses to future consumption demand or government spending on goods and services when the economy is subject to anticipated total factor productivity or investment specific technology shocks the relative strength of the intertemporal substitution effect needs to be enhanced for our model to exhibit positive macroeconomic co movement and business cycle statistics that are consistent with the data

optimal prediction of cyclical downturns abstract in the conventional way of visualizing economic time series the prediction problem does not dichotomize into predicting turning points and predicting conditional means yet the prediction of turning points has always been considered a separate issue in business cycle literature the paper first discusses these issues and then describes a model where the prediction of turning points does separate from the prediction of conditional means using the model an optimal way of predicting turning points is derived and applied to u s data the paper uses time series methodology and the theory of optimal stopping times

new techniques to extract market expectations from financial instruments this paper is a selective survey of new or recent methods to extract information about market expectations from asset prices for monetary policy purposes traditionally interest rates and forward exchange rates have been used to extract expected means of future interest rates exchange rates and inflation more recently these methods have been refined to rely on implied forward interest rates so as to extract expected future time paths very recently methods have been designed to extract not only the means but the whole risk neutral probability distribution from a set of option prices

what does the term structure tell us about future inflation abstract this empirical analysis indicates that for maturities of six months or less the term structure of nominal interest rates provides almost no information about the future path of inflation but does provide information about the term structure of real interest rates however as maturities lengthen to nine and twelve months the nominal term structure begins to contain information about future inflation but ceases to provide information about the real term structure these results are explained by differences in the relative variability of expected future inflation changes and real term structure slopes at different points in the term structure

fiscal dependence on trade taxes and trade policy reform the article focuses on fiscal implications of structural adjustment loans sals from an a priori standpoint and by reference to the experience of five countries three of these countries have had revenue enhancement after trade policy reforms and the other two cases experienced revenue depletion the central point which emerges from the study is that it is not clear that trade liberalisation leads to fiscal enhancement or fiscal depletion both a priori the orising and country analyses demonstrate that a range of outcomes is possible depending upon initial conditions and the components of any reform package

analysis of exchange rate target zones using a limited dependent rational expectations model with jumps this article examines the exchange rate determination in a target zone regime when the bounds can be fixed for an extended period but are subject to occasional jumps in this case the behavior of the endogenous variable is affected by the agents expectations about both the occurrence and the size of the jump empirical results using data for the franc mark exchange rate provide support for the nonlinear model with time varying realignment probability and indicate that the agents correctly anticipated most of the observed changes in the central parity

stochastic processes for interest rates and equilibrium bond prices default free bonds represent in essence money sold forward the investor gives dollars say to the government now in exchange for a contract which promises to pay with probability one a given number of dollars at maturity and possibly a stream of intermediate coupon payments prior to maturity only recently have financial economists begun to examine the pricing of those bonds in a portfolio context in that framework nominal liquidity premiums or risk premiums on long term default free bonds are attributable to uncertainty about taste technological and price level changes which may occur prior to maturity of the bonds and prior to each coupon payment if any to the extent that the investor is unable to diversify away that uncertainty there is a systematic risk attached to the marginal utility which he or she can derive from the use in consumption or investment of the dollar payoffs on the bonds in some term structure models the instantaneous or short term rate of interest denoted here as a function of time t by r t in nominal terms and r t in real terms can be taken as a sufficient statistic1 for the source of systematic uncertainty about the marginal utility of the proceeds to be derived from defaultfree bonds maturing beyond the next instant e g merton 1974 vasicek 1977 cox ingersoll and ross 1977 specific assumptions about tastes technology and utility functions lead to specific equilibrium stochastic processes for the instantaneous short term riskless rate and longer term bond prices which are modelled as functionally dependent upon maturity and that short term riskless rate if a closed form solution exists for the long term bond price as a function of maturity and the short term interest rate it will be conditional inter alia on the parameters of the stochastic process for that short term rate marsh 1981 proposed that the closed form solutions could be tested in terms of the restrictions implied cross sectionally on the parameters of the time series process for the returns or prices of longer term bonds each with a given term to maturity for an analogy outside the term structure literature think of the closed form solution given by black and scholes 1972 for the price of an option on a nondividend paying stock with lognormal price dynamics given the model the cross section of time series for the changes in prices for each of the several options written on the same stock are not unrestricted their dispersion is functionally linked to the same volatility parameter for the stock price thus the option model including
