the fisher hypothesis and the forecastability and persistence of inflation abstract for the period 1860 to 1939 the simple correlation of the u s commercial paper rate with the contemporaneous inflation rate is 0 17 the corresponding correlation for the period 1950 to 1979 is 0 71 this paper attributes this apparent change in the fisher relation to differences in the stochastic process of inflation rather than a change in any structural relationship between interest rates and expected inflation contrary to recent claims in the literature there is little evidence of inflation non neutrality in data from the pre world war i period

a note on nonstationarity structural breaks and the fisher effect abstract we find empirical evidence that inflation nominal and real interest rates in the us are trend stationary with a structural break in both the unconditional mean and the drift rate of a deterministic trend which occurs shortly after the change in operating procedures of the fed in september 1979 this finding casts some doubts on cointegration tests of the long run fisher effect conducted in recent studies since the results of these tests can be affected by the existence of common structural breaks in the series we propose an alternative test of the fisher effect based on a var representation in appropriately detrended variables we find strong support for the fisher effect both in the medium term and in the long term

tips from tips the informational content of treasury inflation protected security prices treasury inflation protected securities tips are frequently thought of as risk free real bonds using no arbitrage term structure models we show that tips yields exceeded risk free real yields by as much as 100 basis points when tips were first issued and up to 300 basis points during the 2007 2008 financial crisis this spread predominantly reflects the poorer liquidity of tips relative to nominal treasury securities other factors including the indexation lag and the embedded deflation protection in tips play a much smaller role ignoring this spread also significantly distorts the informational content of tips break even inflation a widely used proxy for expected inflation

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

the effects of inflation uncertainty on interest rates a nonlinear approach in this article we investigate the effects of inflation variability on short term interest rates within a nonlinear smooth transition regression framework the test results suggest that only the conditional mean of the inflation is a nonlinear process whereas the conditional variance is time variant but linear using the square root of conditional variance as a proxy for inflation risk we estimate fisher equation augmented with inflation risk although the estimated fisher equations suggest that inflation risk reduces short term interest rates we find that the effects of inflation risk on interest rates are regime dependent particularly we find that the negative effects of inflation variability on nominal rates are greater in low inflationary regimes when compared to high inflationary regimes on the other hand it is found that both inflation and inflation uncertainty raise the expected inflation effect

network effects software provision and standardization in this paper we examine the software provision decision of software firms the provision decision by software firms determines the value and hence the market share of competing hardware technologies we show how the provision decision by software firms determines whether multiple hardware technologies are supported in equilibrium or whether there is de facto standardization with only one hardware technology supplied with software in equilibrium we show that when consumers place a high value on software variety there is a suboptimal amount of standardization by the market

a new approach to decomposition of economic time series into permanent and transitory components with particular attention to measurement of the business cycle abstract this paper introduces a general procedure for decomposition of non stationary time series into a permanent and transitory component allowing both components to be stochastic the permanent component is shown to be a random walk with drift and the transitory or cyclical component is a stationary process with mean zero the decomposition methodology which depends only on past data and therefore is computable in real time is applied to the problem of measuring and dating business cycles in the portwar u s economy we find that measured expansions and contractions are of roughly equivalent duration and that our dating of cyclical episodes tends to lead the traditional nber dating and to a lesser extent the growth cycle chronology of zarnowitz and boschan 1977

trend inflation and monetary policy regimes in japan abstract this paper examines the dynamics of trend inflation in japan over the last three decades based on the smooth transition phillips curve model we find that there is a strong connection between the trend inflation and monetary policy regimes the results also suggest that the introduction of the inflation targeting policy and quantitative and qualitative easing in the beginning of 2013 successfully escaped from the deflationary regime but were not enough to achieve the 2 inflation target finally our results indicate the significance of exchange rates in explaining the recent fluctuations of inflation and the importance of oil and stock prices in maintaining the positive trend inflation regime

inflation dynamics when inflation is near zero this paper discusses the likely evolution of u s inflation in the near and medium term on the basis of 1 past u s experience with very low levels of inflation 2 the most recent japanese experience with deflation and 3 recent u s micro evidence on downward nominal wage rigidity our findings question the view that stable long run inflation expectations and downward nominal wage rigidity will provide sufficient support to prices such that deflation can be avoided we show that an inflation model fitted on japanese data over the past 20 years which accounts for both short and long run inflation expectations matches the recent u s inflation experience quite well while the model indicates that u s inflation might be subject to a lower bound it does not rule out a prolonged period of mild deflation going forward in addition our micro evidence on wages suggests no obvious downward rigidity in the firm s wage costs downward rigidity in individual wages notwithstanding as a consequence downward nominal wage rigidity may provide little offset to deflationary pressures in the current u s situation despite some circumstantial evidence that this channel might have been at work in the past

mean reversion in interest rates new evidence from a panel of oecd countries previous studies show that the standard univariate unit root tests cannot reject the hypothesis that interest rates follow integrated processes in this paper the authors pool interest rate data of twelve oecd countries and implement a multivariate test it is found that the unit root hypothesis can be decisively rejected copyright 1996 by ohio state university press

is inflation sticky abstract new keynesian sticky price models predict that monetary policy can affect real variables however they also predict that inflation can be reduced without depressing output or employment in fact bringing down inflation is costly presenting a challenge to the new keynesian model two departures from the new keynesian model predict costly disinflation one assumes sticky inflation rather than sticky prices while the other assumes less than perfectly rational expectations taking into account information from surveys of inflation expectations i find the evidence suggests that inflation is not sticky and that inflation expectations are less than perfectly rational

learning from trading the incorporation of diverse information into asset prices is empirically examined in an actual securities market with multiple rounds of trade using prices of israeli index and nominal bonds of equal maturity we calculate implied expectations of inflation that has already occurred butfor which the official statistic has not yet been announced learning is defined as the convergence of these expectations to the actual level of infzation in the period after the end of the month but before the announcement of the official statistic wefind that the variance of the injiation expectation errors decreases with trading days in this period the decline in the variance suggests that investors learn by repeatedly observing prices about the distribution of other investors information we also find a positive relation between the dispersion of relative price changes and the size of the inflation expectation errors on thefirst round of trade the correlation diminishes as

are oil shocks inflationary asymmetric and nonlinear specifications versus changes in regime this paper identifies a structural break in core u s inflation phillips curves such that oil prices contributed substantially before 1981 but since that time pass through has been negligible this characterization is robust to a variety of re specifications and fits the data better than asymmetric and nonlinear oil price alternatives evidence does not support the hypotheses that declining energy intensity or deregulation of energy producing and consuming industries played an important role monetary policy did not itself become less accommodative of oil shocks but may have helped create a regime where inflation is less sensitive to price shocks more generally

pirated for profit this paper explains why a software manufacturer may permit limited piracy of its software piracy can be viewed as a form of price discrimination in which the manufacturer sells some of the software at a price of zero in the presence of significant network externalities for the software it may be profit maximizing for the software manufacturer to tolerate piracy by home consumers most of whom have a low willingness to pay this can increase the demand for the software by business users

the effects of expected inflation on real returns in the argentine indexed bond market abstract a relatively unrestricted market in goverment indexed bonds operated in the high inflation argentine economy from 1975 through 1982 the indexed bond yields from this period provide an interesting opportunity to examine the relation between real interest rates and expected inflation the test results support the hypothesis that expected inflation is a significant source of variation in real interest rates depressing the real yields on indexed bonds

conditional funding costs of inflation indexed and conventional government bonds abstract this paper employs the predictability of monthly excess returns of uk conventional and index linked gilts to study the risk premiums of nominal and real bonds the estimates of a single latent variable model suggest that indexed gilts of medium and long maturities require half the risk compensation of conventional gilts the government can significantly reduce its long run borrowing costs through issuing inflation index linked debt however the inflation indexation of bonds with maturities less than 3 years does not significantly reduce their risk compensation membership in the exchange rate mechanism did not significantly change the risk compensation of conventional and indexed gilts

inflation and real stock returns revisited i introduction this article empirically reinvestigates the relationship between real stock returns and inflation according to fisher 1930 1 in an efficient market real stock returns should reflect expectations only about real factors such as growth in output and time preference of savers such that real stock returns and inflation should vary independently in other words on average investors are fully compensated for erosions in purchasing power over time however this so called generalized fisher hypothesis has received little empirical support while kaul 1990 boudoukh and richardson 1993 solnik and solnik 1997 madsen 2005 and ryan 2006 find positive or weakly positive correlation between stock returns and inflation most empirical studies including nelson 1976 fama 1981 1983 geske and roll 1983 gultekin 1983 kaul 1987 and solnik 1983 uncover a negative effect of inflation anticipated and or unanticipated on real or nominal stock returns these apparent inconsistencies between the data and the predictions of economic theory have been termed as the stock return inflation puzzle and cited as evidence of monetary nonsuperneutrality or irrationality and market inefficiency 2 to reconcile the seemingly conflicting contributions danthine and donaldson 1986 provide a rational expectations equilibrium model in which a negative relation between stock returns and inflation arises from non monetary sources e g a real output shock and a positive relation is driven by purely monetary sources stulz 1986 marshall 1992 and bakshi and chen 1996 also assert that stock returns may be negatively correlated with inflation especially when the source of inflation is related to nonmonetary factors evidently hess and lee 1999 khil and lee 2000 and lee 2003 find that while monetary shocks drive a positive correlation real fiscal or real output shocks result in a negative correlation between stock returns and inflation from a different perspective kaul 1987 1990 argues that the relation between these two variables depends on both the money demand and the money supply specifically while the combination of money demand effects with a countercyclical monetary response accentuates a negative correlation money demand shocks along with a procyclical monetary response lead to a neutral or positive correlation between real stock returns and inflation similar arguments can be found in day 1984 kaul and seyhun 1990 boudoukh richardson and whitelaw 1994 and gallagher and taylor 2002 and are supported by compelling empirical evidence see e g kim 2003 lee 1992 as an alternative this article models the real stock return inflation relationship as intrinsically dynamic explicitly distinguishing between the short run and the long run such a distinction is crucial because imperfect information rigidity and or contractual obligations are more prevalent in the short run than in the long run in that sense the response of real stock returns to inflation could differ in the short run versus long run moreover we assess the long and short run impacts of inflation uncertainty on real stock returns as argued the real costs of inflation are associated with its uncertainty greater inflation uncertainty resulting from higher inflation may lead to economic inefficiency lower real investment and unemployment thereby reducing economic growth thus it is interesting to see if there are independent effects of inflation uncertainty on real stock returns both in the short run and in the long run in so doing this article uses an innovative econometric technique to explore the long and short run relationships between real stock returns and inflation both anticipated and unanticipated and the relationships with inflation uncertainty it departs from earlier work and complements recent evidence in at least three aspects

portfolio selection with inflation linked bonds and indexation lags abstract we derive the price of inflation indexed bonds of which the payments are linked to a lagged price index and solve for the optimal bond portfolio under both inflation and indexation lags in closed form we show that indexation lags increase the number of state variables characterizing both the bond prices and the optimal portfolio the lag induced state variables affect the future investment opportunity and hence further arm investors with the tools for hedging inflation risk that is however unhedgeable if there is no indexation lag we find that the optimal portfolio accounts for the indexation lags by also exploring the historical information and increases investors welfare therefore we document a positive effect of the indexation lags that are typically considered as a type of market friction

inflation risk premia in the term structure of interest rates this paper estimates the size and dynamics of inflation risk premia in the euro area based on a joint model of macroeconomic and term structure dynamics information from both nominal and index linked yields is used in the empirical analysis our results indicate that the inflation risk premium on euro area 10 year nominal yields was approximately equal to 20 basis points on average over the 1999 2007 period the inflation premium has also been subject to moderate but statistically significant fluctuations for the post 2003 period in which reliable index linked bond prices are available our results suggest that increases in the raw break even inflation rate above 2 the upper bound of the european central bank s definition for price stability have mostly reflected variations in the inflation risk premium while long term inflation expectations have remained well anchored

tracking u s inflation expectations with domestic and global indicators abstract are foreign variables important for tracking u s inflation expectations this paper estimates a reduced form model that takes both domestic and global indicators of economic slack and inflationary pressures into account our main findings point towards the instability of the estimated parameters over the last four decades in particular global indicators appear to have played a statistically significant role in shaping forecasters expectations until the mid 1980s by contrast the u s monetary policy stance turns out to be relevant in the 1980s and 1990s we relate this finding to the more aggressive monetary policy conduct implemented by the fed since the end of the volcker experiment

inflation real returns and capital investment we find evidence for the hypothesis of mundell 1963 and tobin 1965 that the expected real return component of interest rates is negatively related to the expected inflation component in the mundell tobin model the variation in expected real returns is caused by the variation in expected inflation our evidence suggests however that the variation in expected real returns is more fundamentally an outcome of the capital expenditures process equilibrium expected real returns vary directly with capital expenditures in order to induce equilibrium allocations of resources between consumption and investment this positive relation between expected real returns and real activity which comes out of the real sector combines with a negative relation between expected inflation and real activity which is traced to the monetary sector thus inducing the negative relation between expected inflation and expected real returns predicted by mundell and tobin but explained in terms of a model much different from theirs

real and nominal effects of central bank monetary policy abstract we examine the impact of monetary policy using israeli data on nominal and indexed bonds which allow us to decompose nominal interest rates into inflation expectations and ex ante real interest rates we find that a monetary policy shock introduced by raising the overnight rate the bank of israel charges member banks raises real interest rates but lowers inflation expectations long term real interest rates are less impacted than short term rates lastly monetary shocks affect the exchange rate between the israeli currency and the us dollar our estimates are robust to numerous modifications to the basic var model

information aggregation inflation and the pricing of indexed bonds using daily prices of indexed bonds between 1970 and 1979 we test whether announcements of the israeli cpi contain information that is not already reflected in bond prices the results indicate that bond prices reflect about 85 percent of the new information about inflation as it occurs i e when the central bureau of statistics samples prices the announcement of the cpi 15 days after the end of the sampling period causes the remaining 15 percent adjustment in bond prices this evidence raises questions about the empirical importance of misperceptions about inflation as a source of nonneutrality in monetary policy

the real thing a dynamic profile of the term structure of real interest rates and inflation expectations in the united kingdom 1982 89 this article estimates real interest rates and inflation expectations from market observable data without assuming anything about the form of agents expectation formation mechanism by examining prices of index linked and conventional gilt edged securities form the u k bond market real interest rates and inflation expectations are computed quarterly beginning 1982 2 for up to fourteen maturities ranging from 1988 to 2024 copyright 1990 by the university of chicago

expected inflation unexpected inflation and relative price dispersion an empirical analysis abstract using inflation expectations extracted from index bond prices we examine the relations between expected inflation unexpected inflation and relative price dispersion in stable and volatile monetary regimes we find that expected inflation is positively related to relative price dispersion in the high inflation period and that inflation shocks are positively related to relative price dispersion in the low inflation period

inflation and real interest rates on assets with different risk characteristics given the importance of ex ante real interest rates to economic decision making it is no surprise that much empirical research focuses on them 1 several recent studies find that the ex ante real returns for short term u s treasury securities are not constant and are negatively correlated both with inflation and with nominal interest rates this paper examines the extent to which these findings hold for assets of longer maturity are robust with respect to the choice of price index and are stable over time we expand the set of assets studied to include those of longer maturity both publicly and privately issued for two reasons first their ex ante real returns may differ substantially from that of a short term nominally riskless security second because longer maturity assets have risk characteristics closer to capital their ex ante real returns are potentially more relevant for investment and savings decisions we explore the use of various price indices because the index used in most studies the consumer price index severely overstates inflation during the 1970s as a result of its inappropriate treatment of residential housing costs 2 this overstatement casts doubt on an important finding of previous studies that there are long stretches of time during the 1970s when ex ante real rates are significantly negative given the existence of holding costs for the goods relevant to most price indices and the absence of a riskless real return no arbitrage conditions are violated by a negative ex ante real rate however its persistence is problematical because asset holders are typically assumed to have a positive rate of time preference which ensures a positive ex ante real rate in the long run we find that before 1979 a negative relationship of ex ante real rates both with inflation and with nominal interest rates appears for the longer maturity assets as well as the short term nominally riskless asset indeed the relationship grows

real interest rates and inflation an ex ante empirical analysis we develop a method of measuring ex ante real interest rates using prices of index and nominal bonds employing this method and newly available data we directly test the fisher hypothesis that the real rate of interest is independent of inflation expectations we find a negative correlation between ex ante real interest rates and expected inflation this contradicts the fisher hypothesis but is consistent with the theories of mundell and tobin darby and feldstein and stulz we also find that nominal interest rates include an inflation risk premium that is positively related to a proxy for inflation uncertainty

real and nominal interest rates under uncertainty the fisher theorem and the term structure this paper examines the relation between nominal and real interest rates and the nominal and real term structure under uncertainty we show that two separate risk terms cause the fisher theorem to fail one risk term is related only to the variability of money prices while the other is related to the purchasing power riskiness of the nominal bond monetary policy can affect the value of both these risk terms we also show that the pure expectations hypothesis of the term structure fails for both real and nominal bonds because of risk premia even if the economy is neutral with respect to monetary policy monetary policy can alter the nominal term structure

interest rates and monetary policy uncertainty abstract this paper analyzes a model in which optimizing households are uncertain about monetary policy and learn about it over time in this model the variance of changes in nominal and ex post real interest rates increases with the variance of the household s predictive distribution over money growth a positive relation between unexpected changes in nominal interest rates and the money stock results from monetary policy uncertainty finally if money growth covaries negatively with real wealth an increase in monetary policy uncertainty increases the expected real rate of interest and decreases the nominal rate of interest

do expected shifts in inflation affect estimates of the long run fisher relation recent empirical studies suggest that nominal interest rates and expected inflation do not move together one for one in the long run a finding at odds with many theoretical models this article shows that these results can be deceptive when the process followed by inflation shifts infrequently we characterize the shifts in inflation by a markov switching model based upon this model s forecasts we reexamine the long run relationship between nominal interest rates and inflation interestingly we are unable to reject the hypothesis that in the long run nominal interest rates reflect expected inflation one for one

long term real interest rates evidence on the global capital market the steady removal of capital controls and the consequent increase in international capital flows has led to a growing belief that there is now one global capital market with a single world real interest rate at its core we review the evidence on international real interest rate behaviour using alternative measures of real interest rates including those obtained from the growing set of inflation adjusted government bonds using a range of statistical tests we find that it is hard to argue that real interest rates are converging to single world rate though international factors are important moreover the large and persistent differences in real interest rates across countries cannot be explained in terms of real exchange rate expectations macroeconomic indicators from the countries concerned appear to play some role in accounting for these differences copyright 1999 by oxford university press

the benefits of relationship lending in a cross country context a meta analysis relationship lending may create benefits for borrowers by reducing information asymmetries however empirical evidence is mixed we conduct a meta analysis to summarize and explain the heterogeneity in the results in the literature using hand collected information from 101 studies in the united states europe asia and latin america from 1970 to 2010 we find that strong relationships are generally beneficial for borrowers but lending outcomes differ across the relationships dimensions long lasting exclusive and synergy creating bank relationships are associated with higher credit volume and lower loan rates these benefits are more likely in the united states and in countries where bank competition is high they are not related to the importance of small and medium sized enterprises in an economy suggesting that prevalence of relationship lending does not necessarily come along with borrower benefits our inferences are robust when we control for observed systematic heterogeneity in the original

short term interest rates as predictors of inflation on testing the hypothesis that the real rate of interest is constant in an innovative and provocative paper in this review eugene fama presents evidence which appears to be consistent with the joint hypothesis that the real rate of interest ignoring taxes is a constant and that the market for u s treasury bills is efficient in the sense of embodying rational expectations those findings are strikingly at variance with a long list of previous studies which seemed to support the view that the real rate of interest varies over time and can be related to economic variables such as real output monetary policy and so forth 2 the methodologies which lead to these contradictory conclusions are quite different previous studies had followed the lead of irving fisher by relating nominal interest rates to distributed lags on past rates of inflation 3 these distributed lags are generally interpreted as approximations to the market s expected rate of inflation and thus any remaining variation is attributed to variation in the real rate 4 fama s methodology on the other hand draws on the fact that the difference between the market interest rate and the subsequently observed rate of inflation the ex post real interest rate consists by definition of the ex ante real interest rate plus a pure forecasting error 5 the hypothesis of market efficiency implies that these forecasting errors must be serially random thus observing ex post real rates is equivalent to observing ex ante real rates with random measurement error these errors of course confound the problem of identifying variation in the ex ante real rate in this paper we will argue that the relative magnitude of these measurement errors is such that the tests carried out by fama were not powerful enough to reject the joint hypothesis that the ex ante real rate is a constant and expectations are rational more powerful tests which are presented in this paper using the same data do lead to rejection of that hypothesis of course rejection
