Does monetary policy affect the long-run expectations of non-stationary real interest rates?

In this article, we analyse whether the monetary policy affects the long-run expectation of the non-stationary real interest rate. The analysis is conducted through Beveridge–Nelson trend decomposition within a cointegrated vector autoregressive model based on the New Keynesian framework. We suggest an augmented test of the conventional co-integration test on the non-stationarity of the real interest rate, which checks whether the co-integration coefficient of inflation is one and the output gap affects the co-integration equilibrium of the nominal interest rate. We further suggest decomposing the long-run expectation of the non-stationary real interest rate into three trends: the interest rate shock (including the monetary shock), inflation shock and output gap shock. According to empirical analyses using monthly US data after the Korean War, the long-run expectation of the non-stationary real interest rate contains an interest rate shock trend and the impulse of the federal fund target rate induces a significant response of the interest rate shock trend. However, the interest rate shock trend has a very small portion of the long-run expectation of the non-stationary real interest rate, which may explain why the monetary policy was not particularly effective in the economic recovery after the global financial crisis.     

Long-run estimates of money demand: new evidence from East Asian countries and the presence of structural breaks

Conventionally, the money demand function is estimated using a linear regression of the logarithm of money demand on a number of variables. In this article, we aim to estimate the long-run properties of money demand specification for a number of East Asian economies and within a panel framework with the presence of structural breaks. Various country-specific coefficients are allowed to capture inter-country heterogeneities. Consistent with theoretical postulates, it is found that (a) the demand for money in the long-run positively responds to real income and inversely to the interest rate spread, inflation, the real effective exchange rate and the US real interest rate; (b) the long-run income elasticity is greater than unity; and (c) both the currency substitution and capital mobility hypotheses hold. The empirical findings in this article can provide useful policy guidelines to the East Asian countries’ central banks in their quest for price stability. If one of the primary objectives of these countries is to minimize price instability, they should avoid creating unnecessary disequilibrium in the money market, while the employment of cointegration with the presence of structural breaks clearly recommends to central banks to use the supply of money to attain price and macroeconomic stability.     

Revisiting the US money demand function: an application of the Lagrange multiplier structural break unit root test and the bounds test for a long-run relationship

In this article, we examine the issue of a levels relationship and stability of the US money demand function over the period 1959:01 to 2004:02. We use the Lagrange multiplier structural break unit root test and the bounds testing approach to a long-run relationship in levels of the variables, namely real money demand, nominal interest rate and real income. We find greater evidence for a long-run relationship in levels and stability of the US money demand function when we use M2 as a proxy for money demand. However, we find little evidence for a long-run relationship between M1 and M2 with their determinants for the recent period, spanning the last decade or so.     

Real interest rate parity in Asian countries: evidence from the quantile unit root test

This article studies the real interest rate parity (RIP) for several Asian countries. This is done by examining the stationarity in the real interest rate differentials (rids) with respect to the US using the quantile unit root test. Our results show that rids exhibits unit-root behaviours in the lower quantile levels, and mean reversion in the upper quantile levels. Furthermore, large positive shocks tend to induce strong mean reversion and the adjustment towards the long-run equilibrium level is faster as rids gets larger, with shorter half-lives in the extreme quantile levels.     

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.     

Monetary policy effectiveness and stock market cycles in ASEAN-5

This article examines the asymmetric effects of monetary policy on real output in bull and bear phases of stock market in five ASEAN economies (Malaysia, Singapore, Indonesia, the Philippines and Thailand) using the recently developed pooled mean group (PMG) technique. Stock market cycles are identified by employing Markov switching models and the rule-based nonparametric approach. Estimating the models using monthly data from 1991:1 to 2011:12, the results show that monetary policy (measured by short-term interest rate) has a negative and statistically significant long-run effect on real output in bull and bear market periods while the effects are stronger in bear periods than bulls. In the short run, there is no statistically significant relationship between monetary policy and real output. These results are consistent with finance constraints (capital market imperfection) models that predict that monetary policy is more effective during bear periods than bulls.     

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.     

Estimation of a German money demand system – a long-run analysis

This study presents a multivariate analysis of the stability of long-run relationships between variables that influence the conduct and transmission process of the German monetary policy. The initial VAR comprises the variables real money M3, real GNP, the inflation rate, a long-term and a weighted short-term interest rate. A multivariate approach has been chosen, as this allows for more than one cointegration relationship and to test restrictions on the cointegration space. In contrast to most other studies on German monetary policy, three stable and economically plausible cointegration relationships are obtained simultaneously within the framework of the Johansen procedure: a money demand relationship, a long-run Fisher effect and a long-run relationship between the short- and the long-term interest rate. It is apparent that the structural break of German reunification can be modelled incorporating dummy variables in the model.

The Political Economy of Real Exchange Rate Behavior: Theory and Empirical Evidence for Developed and Developing Countries, 1960–2010

Empirical results of testing the PPP hypothesis have constantly shown that relative prices do not converge to the same level, either in the short or the long run. Therefore, the PPP explanation of the real exchange rate does not provide a reasonable measure of competitiveness at the international level. This article puts forth a different approach based on the works of Ricardo, Marx, Harrod and Shaikh. It argues that the real relative unit labor cost is the main factor explaining the long-run behavior of the real exchange rate. The second section of the article explains the theoretical underpinnings of our approach. The third section analyzes the role of the real interest rate differential in explaining real exchange rate misalignments. In the fourth section, we present a graphical analysis of the interrelation among the real effective exchange rate, the real unit labor cost ratio, the short-run real interest rate differential and the trade balance for 16 OECD countries, Taiwan and three developing countries for the period 1960–2010. The fifth section investigates the long-run relationship between the latter three indexes through co-integrating and error correction models using the ARDL–ECM framework. The last section provides our conclusions.     

Does oil price variability affect ASEAN exchange rates? Evidence from panel cointegration test

Using panel data, this article investigates the long-run relationship between real oil prices and real exchange rates for selected ASEAN countries by utilizing quarterly data from 1973:Q1 to 2013:Q4. The modelling implementation starts with the determination of the stationarity condition of the variables which are found to be integrated of order one. Using Maddala and Wu’s (1999) panel cointegration test, the article finds evidence of cointegration among the variables. The fully modified OLS (FMOLS) and dynamic OLS (DOLS) are then used to estimate the long-run relationship between the variables, followed by applying Toda–Yamamoto causality test. The findings exhibit bidirectional causality between real oil prices and real exchange rates in the long run, where it is highly significant.     

Stability of money demand function revisited in China

As China's economic reforms have undergone significant structural changes after 1979, it has been rather difficult to formulate a stable money demand function over the period following that year. While previous literature on the long-run relationship of money demand in China shows the existence of stable money demand, this article revisits the stability of the China money demand function over the period after 1979. To employ the unit root tests and the cointegration tests with structural break, the empirical evidence demonstrates that economic and financial deregulation did affect the stability of demand for money in China over the period 1977 to 2002. Moreover, the estimated long-run income and interest elasticity are respectively 1.01 (1.11) and ?0.14 (?0.08) using the real M1 (M2) equation. In addition, real income and the interest rate are found to be weakly exogenous. We overall do find structural breakpoints mainly in 1980 and 1993, and they look to match clearly with corresponding critical financial and economic incidents.     

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 stable demand for money despite financial crisis: the case of Venezuela

The demand for broad money in Venezuela is investigated over a period of financial crisis and substantial exchange rate fluctuations. The analysis shows that there exist a long-run relationship between real money, real income, inflation, the exchange rate and an interest rate differential, that remains stable over major policy changes and large shocks. The long-run properties emphasize that both inflation and exchange rate depreciations have negative effects on real money demand, whereas a higher interest rate differential has positive effects. The long-run relationship is finally embedded in a dynamic equilibrium correction model with constant parameters. These results have implications for a policy-maker. In particular, they emphasize that with a high degree of currency substitution in Venezuela, monetary aggregates will be very sensitive to changes in the economic environment.     

Long-run impact of increased wage pressure

An unanticipated permanent increase in wage pressure is analyzed in a dynamic general-equilibrium model combining standard theory of capital accumulation and monopolistic wage setting. The long-run (steady-state) implications are identical percentage reduction in employment, consumption, and capital stock whereas wages and the real interest rate are unchanged. The reduction in employment on impact is larger than the steady-state reduction whereas wages rise and the real interest rate declines on impact.     

The effectiveness of monetary policy and output fluctuations: An asymmetric analysis

Previous studies have investigated asymmetries in the effects of monetary policy on the real economic activity by using either vector autoregressive (VAR)-based regime-switching models with smooth transition technique or Gaussian functions to parameterise the dynamic effects of structural shocks on the economy. These kinds of VAR models assume asymmetry as a short-run relationship between the series since the long-run neutrality hypothesis of money states that monetary policy can only affect productive capacity of the economy in the short run, but not in the long run. The recent theoretical literature shows that this hypothesis is not quite right. Thus, this paper examines the extent to which monetary policy has a long-run asymmetric effect on output in a number of Organisation for Economic Co-operation and Development countries by using a nonlinear hidden cointegration analysis within a likelihood-based panel framework. The findings indicate that there is a long-run relationship between the real interest rate as an indicator of monetary policy and the growth rate of real output in five countries out of nine under review. This gives support for the view that output has responded asymmetrically to the real interest rate changes. The economic implication of our results is that monetary policy affects positive and negative output fluctuations differently.     

Central Bank's interventions and the Fisher hypothesis: a threshold cointegration investigation

The long-run relationship between nominal interest rates and inflation is examined, allowing for structural breaks and asymmetric mean reversion. From a Threshold AutoRegressive (TAR) test applied to the residuals of the cointegration relationship (while allowing for both a break in the mean of the long-run equation and a smooth regime-transition), there is strong evidence for non-linear mean reversion properties for the real interest rates of the US Treasury Bill market. This suggests asymmetric changes to inflation shocks in the Central Bank's reaction function. The existence of different regimes is consistent with some interpretations of the monetary policies run by the Fed, such as credibility and opportunism.     

Has M2 demand in the USA become unstable? evidence from an error-correction model

The purpose of this paper is to estimate an appropriate broad-money demand function for the United States and to examine its stability after 1987, when the Federal Reserve System began using M2 as a policy guide. Special attention is paid to the model specification, its dynamic structure, and to its cointegration properties. The results from various dynamic error-correction models suggest that: (i) the money demand relationship is stable; (ii) most previously estimated models have undoubtedly misspecified the interest rate variable; (iii) interest-rate variability is another important determinant of real money demand; and (iv) in contrast of previous studies, the long-run scale variable is real GDP, whereas real consumer spending is the short-run scale variable. The sample period examined is 1953:1 to 1991:4.     

Financial reforms and credit growth in Nigeria: empirical insights from ARDL and ECM techniques

In the last 37 years, Nigeria has undergone several stages of financial reforms with different impacts on the economy. This paper analyses the impact of these financial reforms on credit growth in Nigeria using annual data from 1980 to 2016. The research work hinges on the theoretical underpinning of McKinnon-Shaw hypothesis on the relevance of financial reforms in a lagging economy. Analysing the data with autoregressive distributed lag error correction representation and bounds testing techniques, we find evidence supporting this hypothesis, and specifically that at higher real interest rates there is increased financial intermediation evidenced by credit growth. Other findings are that in the long-run, financial system deposits, inflation rate and per capita GDP are strong asymmetrical predictors of credit growth and real interest rates (the financial reform indicator), while the short-run relationships are indicator-specific. We further show that a long-run cointegration relationship exists between domestic credit and other covariates and likewise between the real interest rate and its regressors.     

The demand for money in Austria

In this paper, the demand for real money M1, M2, and M3 is estimated for Austria over the time period 1965–96. The modelling takes place within the framework of a small vector autoregression. To estimate the demand for money, two-equation error-correction models are constructed, which contain the short-run dynamics and the long-run economic equilibrium. It is found that a stable money demand exists for all monetary aggregates. The long-run equilibrium of M1, after accounting for a structural break in 1979, can be characterised as a classical type of money demand, with no interest rate effects and an elasticity of one for real GDP. In the case of M2 and M3, we find a unit coefficient on income and a significantly negative influence of a long-term interest rate. The statistical properties of the estimated short-run money demand equations – considering in-sample and out-of-sample tests – are generally very good.

Stock prices and long-run demand for money: evidence from Malaysia

This paper investigates the money demand function for Malaysia in the 1971-1996 period using the multivariate cointegration and error correction model methodology. The results suggest that a stable long-run relationship exist between real M2, the interest rate differential, income and stock prices. Stock prices have a significant negative substitute effect on long-run as well as short-run broad-money demand (M2) and its omission can lead to serious misspecification in the money demand function. The analysis from the vector error correction model (VECM) and the Toda & Yamamoto (1995) causality tests find that money is endogenous and that there is at least a unidirectional relationship between stock prices and real M2. Stock prices Granger cause real M2 indirectly through income between interest rates and stock prices and stock prices and money stock. This paper comes to the conclusion that due to the endogeneity of money, M2 cannot be completely controlled by Malaysia's central bank. Therefore, in formulating future monetary policy, the response of money demand to stock prices should be considered.
