Real and nominal effects of monetary policy shocks

Abstract.  We employ the identification scheme of Kahn, Kandel and Sarig (2002) to analyse the impact of Canadian monetary policy on ex ante real interest rates and inflationary expectations. First, we decompose nominal interest rates into ex ante real rates and inflationary expectations using the methodology of Blanchard and Quah (1989) . Then we estimate a recursive VAR model with innovations in a monetary aggregate and the overnight target interest rate as alternative measures of monetary policy shocks. We find that a negative policy shock raises both nominal and ex ante real interest rates, lowers inflationary expectations and real industrial output, and appreciates the Canadian dollar.     

Inflationary expectations and monetary policy: evidence from Bangladesh

This article first estimates inflationary expectations using a Blanchard–Quah VAR model by decomposing the nominal interest rate into expected inflation and the ex ante real interest rate. Then I utilize this expected inflation along with other macroeconomic variables as inputs to the monetary policy function in a recursive VAR model to identify exogenous policy shocks. To calculate inflationary expectations, I assume that ex ante real interest rate shocks do not have a long-run effect on the nominal interest rate. This article finds that the public expects lower inflation for the future during periods of high inflation. Estimated results from the recursive VAR suggest that a contractionary policy shock increases the real interest rate, appreciates domestic currency, and lowers inflationary expectations and industrial output. However, I find a lagged policy response from Bangladesh Bank to higher inflationary expectations.     

A theorem on interest rate differentials,risk and anticipated inflation

This paper develops a theorem to the effect that the difference in nominal interest rates between two securities of the same maturity but different risk is an increasing linear function of the anticipated rate of inflation. Even when society's inflationary. A preliminary attempt is made to estimate the real risk premiums that finance paper, bankers's, acceptances, commercial paper, certificates of deposit, and Eurodollar deposits command over treasury bills. It is found, for example, that the real risk premium commanded by bankers’ acceptances over treasury bills is five basis points. This means that in a non-inflationary environment, bankers' acceptances would yeild five basis points more than treasury bills. This estimate and the other estimates obtained are not implausiable, but they are probably minimum estimates because of bias in the estimate of inflationary expectations.     

A panel analysis of the fisher effect with an unobserved I(1) world real interest rate

The Fisher effect states that inflation expectations should be reflected in nominal interest rates in a one-for-one manner to compensate for changes in the purchasing power of money. Despite its wide acceptance in theory, much of the empirical work fails to find favorable evidence. This paper examines the Fisher effect in a panel of 21 OECD countries over the period 1983–2010. Using the Panel Analysis of Non-stationarity in Idiosyncratic and Common Components (PANIC), a non-stationary common factor is detected in the real interest rate. This may reflect permanent common shifts in e.g. time preferences, risk aversion and the steady-state growth rate of technological change. We therefore control for an unobserved non-stationary common factor in estimating the Fisher equation using both the Common Correlated Effects Pooled (CCEP) and the Continuously Updated (Cup) estimation approach. The impact of inflation on the nominal interest rate is found to be insignificantly different from 1, providing support of the Fisher effect.     

Monetary Policy, Nominal Interest Rates, and Long–Horizon Inflation Uncertainty

Empirical evidence presented in this paper shows that the predictability of inflation at long horizons varies considerably across countries. Both simple theory and empirical evidence suggest that the crucial factor is the extent to which systematic monetary policy succeeds in preventing a unit root in inflation. The mechanism by which it does this appears however to be complicated by strong empirical evidence that nominal as well as real interest rates have real effects, which implies that monetary policy need not be so vigorous in reactions to inflation. This helps to explain why inflation rates in the US and (especially) Germany have been relatively predictable, despite monetary policy rules which appear to have been barely stabilising. The paper also presents tentative evidence that the power of nominal interest rate effects is inversely related to long–horizon inflation uncertainty, and hence ultimately uncertainty about monetary policy.     

Future inflation and the information in international term structures

This paper extends previous work on the information content of the term structure of interest rates using a newly constructed dataset for the United States, Japan, Germany, Switzerland, France, Belgium and the Netherlands (1982–1991). Results significantly differ from Jorion and Mishkin (1991). Apparently, the relation between the term structure of interest rates and future inflation is highly period- and country-dependent. We provide new evidence that these results may be due to the inability of financial markets to accurately predict a term structure of inflation in combination with the conduct of monetary policy. This probably accounts for large variation in ex post real interest rate levels and the term structure of real interest rates. Consequently, it is unlikely that the term structure of nominal interest rates will serve as a good indicator of future inflationary developments.     

Inflation and real short-term interest rates - A Kalman filter analysis of the term structure

This paper applies the Kalman filter technique to look at the relationship among real interest rates, inflation, and the term structure of interest rate under the expectations hypothesis. Using quarterly data from 1960:1 to 1991:1 for inflation, three month nominal short term interest rates and long term yields with maturities from one to five years, this paper finds that the expectations hypothesis of the term structure holds up well for the data under the assumptions of a time-varying premium and a random-walk real interest rate. In other words, a reconciliation of the expectations hypothesis with the data is attained by assuming time-varying term premium and non-stationary real interest rate.     

Inflationary Expectations, Variable Output, and Exchange-Rate Dynamics

This paper develops a model of exchange-rate dynamics characterized by inflationary expectations held with perfect foresight, sticky wages, and sluggish output adjustment. In this framework monetary expansion initially lowers interest rates because of sluggish output and price adjustment but quite surprisingly produces exchange-rate overshooting or undershooting. Moreover, after its initial depreciation in the overshooting case, the domestic currency temporarily appreciates beyond its new long-run equilibrium level. In the undershooting case, the home currency temporarily appreciates away from its new long-run equilibrium level. Finally, the dynamic real exchange rate-real interest rate relationship at times becomes inverse.     

Government spending and the exchange rate

This paper investigates the effects of govenment spending on real and nominal exchange rates within the context of an open economy equilibrium rational expectations model. The model predicts that both real and nominal exchange rates appreciate in response to anticipated and unanticipated increases in government spending. Empirical evidence from Germany for the period 1975:2–1989:4 provides some weak support for the predictions of the model.     

Alternative passive monetary policies in an inflationary economy

This paper considers three alternative specifications of passive monetary policies in a simple dynamic macroeconomic model of an inflationary economy in which both the dynamics of wealth accumulation and the evolution of inflationary expectations play central roles. These policies include one in which the real stock of money is held fixed; one in which the rate of nominal monetary growth is held constant; and a third in which the real stock of government bonds is held fixed. We compare the dynamic behavior of the system as well as its steady state properties under these alternative policies. Two expectations hypotheses—the adaptive and perfect myopic foresight—are considered and their implications related at some length.     

The intertemporal substitution effect of government purchases on the interest rate: Empirical estimates for the Netherlands

In an intertemporal equilibrium setting, temporary government purchases may affect the real interest rate. A temporary change in the level of government spending does not affect the optimal intertemporal allocation of rational consumers, who will therefore try to maintain their consumption plans. Assuming no change in the supply of goods, there is an excess demand for goods and in a closed economy the real interest rate has to rise to maintain equilibrium at the goods market. In this paper it is examined whether predictions of intertemporal substitution models hold up to the experience of the Netherlands. We extend Barro's empirical work in three ways. First, we construct a new measure of temporary government outlays. Second, we take the time series behaviour of the data concerned into account and employ a less restrictive specification for the equation to be estimated. Third, we examine the intertemporal substitution effect of government purchases onreal interest rates. Our results provide only mixed support for the hypothesis that temporary government purchases raise real interest rates. It turns out that only temporary military outlays affect the nominal and real interest rate.     

Price level determinacy and the choice of policy targets under rational expectations

We show that in a conventional macro model with rational expectations, the government can use monetary policy to peg real interest rates, and still attain a determinate price level provided it also pegs some nominal policy variable, e.g., nominal expenditures.     

The vanishing role of money in the macro-economy: An empirical investigation for India

The recent de-emphasizing of the role of “money” in both theoretical macroeconomics as well as in the practical conduct of monetary policy sits uneasily with the idea that inflation is a monetary phenomenon. Empirical evidence has, however, been accumulating pointing to an important leading indicator role for money and credit aggregates with respect to long term inflationary trends. Such a role could arise from monetary aggregates furnishing a nominal anchor for inflationary expectations, from their influence on the term structure of interest rates and from their affecting transaction costs in markets. Our paper attempts to assess the informational content role of money in the Indian economy by a separation of these effects across time scales and frequency bands, using the techniques of wavelet analysis and band spectral analysis respectively. Our results indicate variability of causal relations across frequency ranges and time scales, as also occasional causal reversals.     

Money, expectations, and interest rates

This paper employs a model of nominal interest rate determination in a framework of rational expectations of inflation. Hypotheses are developed with respect to relative impacts of predictable and unpredictable changes in money supply. These hypotheses are tested using quarterly Italian data from 1966–1975. The nominal monetary base is the measure of money employed and one private and two government bond rates measure nominal interest rates. The results are insensitive to variations in estimation procedure and specification of adjustment processes (and even predictive functions for the monetary base). The rational expectations formulation is well supported in every case.     

The Fisher effect,survey data and time-varying volatility

In this paper we study the Fisher hypothesis using Livingston survey data on inflation expectations. We propose a simple model for the ex-ante real interest rate where the standard deviation of survey forecasts is used to correct for heteroskedasticity. The findings of this paper contradict earlier studies. We find supportive evidence for the Fisher hypothesis that the nominal interest rate and expected inflation move one-for-one both in the short and the long run. Our results also suggest that the change of US monetary policy does not have significant effect on the dynamics of the ex-ante real interest rate such as previous work assumes.     

Revisiting the interest rate–exchange rate nexus: a Markov-switching approach

In this paper the interest rate–exchange rate nexus and the effectiveness of an interest rate defense are investigated empirically. I present a reduced form evidence which characterizes the empirical relationship between interest rates and exchange rates. I use a Markov-switching specification of the nominal exchange rate with time-varying transition probabilities. Empirical evidence from six developing countries: Indonesia, South Korea, the Philippines, Thailand, Mexico, and Turkey indicates that raising nominal interest rates leads to a higher probability of switching to a crisis regime. Thus, the empirical results presented here may support the view that a high interest rate policy is unable to defend the exchange rate. Unlike other studies which consider linear models only, my findings are robust and consistent over different countries and crisis episodes (Asian 1997 crises, Mexico 1994 crisis, and Turkey 1994, 2001 crises). In order to explain the empirical findings, I construct a simple theoretical model by incorporating an interest rate rule in the model proposed by Jeanne and Rose (2002) [Jeanne, O., Rose, A.K., 2002. Noise trading and exchange rate regimes, Quarterly Journal of Economics. 117 (2) 537–569]. The model has multiple equilibria, and under plausible conditions, higher exchange rate volatility is associated with higher interest rates.     

What drives inflation in New Keynesian models?

This paper estimates variants of a small-scale New Keynesian model using observations on inflation, inflation expectations and nominal interest rates. We ask whether those variables alone can tell us something about the time series properties of real marginal costs.     

Money, capital, and real liquidity effects with habit formation

Abstract.  The money in utility model is reconsidered in the presence of endogenous labour and habits. With standard assumptions about preferences and a policy rule that sets the nominal interest rate by adjusting the growth rate of money, the model exhibits superneutrality in the steady state. Nevertheless, habits give rise to real liquidity effects in the short run. After an increase in the nominal interest rate, employment falls, resulting in a fall in capital accumulation and in the short‐ and long‐term real interest rates. The adjustment of the capital stock is non‐monotonic. Employment and the short‐ and long‐term real interest rates may also adjust non‐monotonically. JEL classification: E22, E52, E58     

Modifying Taylor reaction functions in the presence of the zero‐lower‐bound — Evidence for the ECB and the Fed

We propose an alternative way of estimating Taylor reaction functions if the zero‐lower bound on nominal interest rates is binding. This approach relies on tackling the real rather than the nominal interest rate. So if the nominal rate is (close to) zero central banks can influence the inflation expectations via quantitative easing. The unobservable inflation expectations are estimated with a state‐space model that additionally generates a time varying series for the equilibrium real interest rate and the potential output — both needed for estimations of Taylor reaction functions. We test our approach for the ECB and the Fed within the recent crisis. We add other explanatory variables to this modified Taylor reaction function and show that there are substantial differences between the estimated reaction coefficients in the pre‐ and crisis era for both central banks. While the central banks on both sides of the Atlantic act less inertially, put a smaller weight on the inflation gap, money growth and the risk spread, the response to asset price inflation becomes more pronounced during the crisis. However, the central banks diverge in their response to the output gap and credit growth.
