An examination of the Fisher Hypothesis: the case of Turkey

This study examines the famous Fisher Hypothesis (FH) for Turkey. FH asserts that nominal interest rates adjust on a one-to-one basis to expected changes in inflation rates. Using the Johansen cointegration method for the Turkish monthly interest rate and inflation rate data, we find that it is possible to determine the long-run relationship—but not the one-to-one basis—between nominal interest rates and inflation. Our findings suggest that full FH does not hold but there is a very powerfull Fisher effect in the case of Turkey from 1990 to 2003.     

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.     

Central bank inability and Taylor rule in developing countries

This paper seeks to adjust Taylor rule to mimic an environment that has central bank inability (losses). Moreover, the current paper is aiming at investigating the effect of the new features of Taylor rule within a context of a New-Keynesian model on a developing economy. The current paper concludes that we can utilize Taylor rule within a New-Keynesian model to introduce the influence of the central bank inability on the economy. Central bank inability decreases both expected future real interest rate and expected future real output. On the contrary, it increases expected future nominal interest rate and expected future inflation rate. Moreover, we prove that the effect of central bank inability has larger effect on the expected inflation rate more than the influence of targeted inflation rate.     

The Fisher effect: new evidence and implications

Using monthly data in the 1980s and early 1990s, our results do not support the short-run Fisher effect since short-term interest rates are associated with negligible changes in expected inflation. However, inflation and nominal interest rates exhibit common stochastic trends in the long run. Consequently, the correlation between nominal interest rates and inflation rates increases with maturity until they move in a one-to-one relation at long horizon. This is evident by the correlation coefficients of the Johansen test for cointegration that increase with the maturity of US government securities from 2 to 5 years.     

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.     

Interest rates,inflation, and taxes: The foreign connection

In this note it is shown that the existence of taxes on nominal interest receipts in an international setting introduces a non-neutrality in that a change in expected inflation in one country must change at least one expected real interest rate or the path of the real exchange rate.     

Monetary deregulation and inverting the inverted fisher effect

We find evidence that deregulation allowing interest payments on checkable deposits decreased (increased) the sensitivity of the real (nominal) rate of interest to expected inflation. Our results provide further confirmation of the Inverted Fisher Effect.     

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.     

On some neglected implications of the Fisher effect

Following the lead of Fama [American Economic Review 65 (1975) 269–282] and of other influential articles, such as Mishkin [Journal of Monetary Economics 30 (1992) 195–215], it has become standard to interpret the Fisher effect as the ability of short-term interest rate to predict future inflation. However, in this article we demonstrate that by restricting to zero the instantaneous response of expected inflation to an interest rate shock, one can identify a disturbance that economic agents, according to the Fisherian framework, should evaluate as transitory. An important implication of this result is that short-term nominal interest rates cannot be interpreted as predictors, at least not long-run predictors, of inflation. We illustrate this result with an empirical application to US postwar data.     

Evaluating the Fisher effect in long-term cross-country averages

This article uses long-term cross-country data to examine the Fisher hypothesis that nominal interest rates respond point-for-point to changes in the expected inflation rate. The analysis employs bounded-influence estimation to limit the effects of hyperinflation countries such as Brazil and Peru. Contrary to the results in Duck (1993), the present evidence does not support a full Fisher effect. By extending the empirical model to account for cross-country differences in sovereign risk, we find evidence consistent with the idea that interest rates fail to fully adjust to inflation due to variation in the implicit liquidity premium on financial assets.     

Nominal term structure and term premia: evidence from Chile

The downwards trend exhibited in Chile’s nominal term structure since 2003 has been a common pattern shared by other developed and developing economies. To understand the behaviour of the nominal yield curve in Chile, we rely on an affine dynamic term structure model which allows the term structure to decompose into the expected short-term interest rate (related to the monetary policy expectation) and the term premium. We show that most of the fall of long-term interest rates as well as its dynamics are related to the term premium rather than the expected short-term interest rate. Moreover, we find evidence that term premium is driven primarily by the US term premium and domestic nominal uncertainty derived from expected inflation.     

Correct cointegration tests of the long-run relationship between nominal interest and inflation

The Fisher (1930) hypothesis suggests that a long-run equilibrium relationship exists between the non-stationary series: nominal interest and expected inflation. Testing such a cointegrating relationship is complicated by the presence of the unobserved ex antereal rate of interest in residuals from the cointegrating regression. Assumptions concerning the stochastic properties of the expected real rate of interest are examined, and two proxies for the ex antereal rate are employed in multivariate cointegration tests of the Fisher hypothesis.     

The inflationary bias of real uncertainty and the harmonic Fisher equation

Summary. We argue that real uncertainty itself causes long-run nominal inflation. Consider an infinite horizon cash-in-advance economy with a representative agent and real uncertainty, modeled by independent, identically distributed endowments. Suppose the central bank fixes the nominal rate of interest. We show that the equilibrium long-run rate of inflation is strictly higher, on almost every path of endowment realizations, than it would be if the endowments were constant.Indeed, we present an explicit formula for the long-run rate of inflation, based on the famous Fisher equation. The Fisher equation says the short-run rate of inflation should equal the nominal rate of interest less the real rate of interest. The long-run Fisher equation for our stochastic economy is similar, but with the rate of inflation replaced by the harmonic mean of the growth rate of money.Received: 25 February 2005, Revised: 26 May 2005, JEL Classification Numbers: C7, C73, D81, E41, E58.An earlier version of this paper “Inflationary Bias in a Simple Stochastic Economy,” as a 2001 Cowles Foundation Discussion Paper No. 1333.     

Asymmetric monetary policy and the effective lower bound

We use the canonical New Keynesian model to study optimal discretionary policy when the nominal interest rate is constrained by the effective lower bound (ELB). We show that policymakers who seek to minimize a (symmetric) quadratic loss function involving deviations of inflation and output from targets will achieve an average inflation rate below target due to the contractionary effects associated with hitting the ELB. We also characterize optimal discretionary policy for policymakers who view output losses as asymmetric: they place weight on the output gap when output is below potential but place little or no weight on the gap when output is above potential. In comparison to optimal policy using the symmetric loss function, the average inflation rate is higher and closer to the central banks target. Moreover, in response to contractionary demand shocks that push the nominal interest rate to the effective lower bound, policymakers with an asymmetric loss function adopt a policy rate path that remains at the ELB longer but eventually rises more quickly than the path adopted by a policymaker with a symmetric loss function.     

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.     

Macroeconomic Control in the Transforming Chinese Economy: An Analysis of the Long‐Run Effect

This paper analyzes the issue of macroeconomic control in the Chinese economy where there is a dual structure (consisting of a state sector and a non‐state sector) and the financial sector is still under tight control by the government. Given the dual structure and financial repression, when inflation is a severe problem, the authors investigate whether it is possible for the government to bring inflation under control without hampering long‐term economic growth performance. The investigation is conducted within the context of an endogenous growth model that incorporates the two major institutional features of the transforming Chinese economy. The paper evaluates the long‐run effects of changes in government monetary and fiscal policies on the major macroeconomic aggregates. The analysis suggests that increasing in the interest rate on government bonds will reduce inflation without affecting the growth rate of output; while increasing the nominal interest rate on bank deposits will exert a stagflationary effect on the economy: raising the inflation rate but reducing the growth rate of output.     

Determinants of fiscal multipliers revisited

We generalize a simple New Keynesian model and show that a flattening of the Phillips curve reduces the size of fiscal multipliers at the zero lower bound (ZLB) on the nominal interest rate. The factors behind the flatting are consistent with micro- and macroeconomic empirical evidence: it is a result of, not a higher level of price rigidity, but an increase in the degree of strategic complementarity in price-setting – invoked by the assumption of a specific instead of an economy-wide labour market, and decreasing instead of constant-returns-to-scale. In normal times, the efficacy of fiscal policy and resulting multipliers tends to be small because negative wealth effects crowd out consumption, and because monetary policy endogenously reacts to fiscally-driven increases in inflation and output by raising rates, offsetting part of the stimulus. In times of a binding ZLB and a fixed nominal rate, an increase in (expected) inflation instead lowers the real rate, leading to larger fiscal multipliers. Conditional on being in a ZLB-environment, under a flatter Phillips curve, increases in expected inflation are lower, so that fiscal multipliers at the ZLB tend to be lower. Finally, we also discuss the role of solution methods in determining the size of fiscal multipliers.     

Budget deficits,short-term real interest rates and the specification of expected inflation: an empirical investigation

The purpose of this paper is to illustrate whether empirical estimates of the effects of budget deficits on short-term real interest rates are sensitive to the choice of the expected inflation variable. Survey data on expected inflation and the rational expectations method described by Mishkin (1981) are used to construct two measures of the short-term real interest rate. Results for two previous studies on this deficit-interest rate relationship are re-estimated using these measures of expected inflation and the interest rate variables. Additional results reported in this paper further indicate that empirical estimates of the interest rate effects of budget deficits are sensitive to the choice of the expected inflation variable. In addition to the choice of the inflation variable, a number of other robustness tests are included. We are able to conclude that (1) increases in budget deficits do not generally raise short-term real interest rates and (2) short-term real interest rates are not independent of the expected inflation variable.

The rate of interest is always based upon expectation, however little this may be justified by realization. Man makes his guess of the future and stakes his action upon it … Our present acts must be controlled by the future, not as it actually is, but as it appears to us through the veil of chance (Fisher, 1907, p. 213).     

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.
