Does money have a role in the inflation process? Evidence from Australia

Inflation, defined as a sustained increase in the price level, is considered a monetary phenomenon, as it can be explained within the framework of money‐demand and money‐supply relationships. In the extant literature, money growth is shown to remain causally related to inflation across countries and over time, irrespective of the exchange rate regime and stability of the money‐demand function. Nevertheless, emerging literature suggests a diminishing role of money in the conduct of monetary policy for price stability, especially under inflation targeting. Monetary policy in Australia under inflation targeting since 1993 is an example of policy that denies a relationship between money growth and inflation. The proposition that money does not matter insofar as inflation is concerned seems odd in both theory and the best‐practice monetary policy for price stability. This paper uses annual data for the period 1970–2017 and quarterly data for the period 1970Q1–2015Q1. It deploys both the Johansen cointegration approach and the autoregressive distributed lag (ARDL) cointegration approach to investigate for Australia whether money, real output, prices and the exchange rate (non‐stationary variables) maintain the long‐run price‐level relationship that the classical monetary theory suggests in the presence of such stationary variables as the domestic and foreign interest rates. As expected, the empirical findings for Australia are consistent with the classical long‐run price‐level relationship between money, real output, prices and the exchange rate. The error‐correction model of inflation confirms the presence of a cointegral relationship among these variables; it also provides strong evidence of a short‐run causal relationship between money supply growth and inflation. On the basis of a priori theoretical predictions and empirical findings, the paper draws the conclusion that the monetary aggregate and its growth rate matter insofar as inflation is concerned, irrespective of the strategy of monetary policy for price stability.     

ARDL bounds tests and robust inference for the long run relationship between real stock returns and inflation in Australia

This paper conducts an empirical investigation into the long run relationship between real stock returns and inflation in Australia by employing the ARDL bounds tests. There exists a stock return–inflation long run relationship, and the long run parameters are non-linear functions of those of the conditional error correction model. The OLS estimates of the latter model constitute the long run parameter estimates and their standard errors are estimated by delta methods. The long run model estimates so constructed can be biassed and inconsistent, and the delta method is derived assuming asymptotic normality, which does not hold in this investigation. In this paper, to overcome these limitations of the traditional methods, we employ the bias-corrected bootstrap method. As a consequence, the robust and reliable statistical inference can be made on the long run return–inflation relationship. The empirical results show that the expected inflation had no significant effect on real stock returns, while the observed inflation had a significant and negative effect. Furthermore, the data generating process of the returns–inflation relationship was not affected by the change in monetary policy regime in the early 1990s. These findings imply that Australian stocks have been very effective instruments for hedging against expected inflation. Because of the resilience of Australian economy to the current global financial and economic crisis, this finding has implications for long term domestic and foreign investors in Australia.     

通货膨胀、汇率波动与货币政策——基于符号约束的贝叶斯VAR模型实证研究

通过构建通货膨胀形成的理论模型,本文运用符号约束的贝叶斯VAR方法探讨通货膨胀和汇率波动对产出增长的影响。结果发现：实际利率对通货膨胀和人民币升值冲击均有较大的响应,且受通货膨胀的影响更大,即稳定价格的货币政策比稳定汇率的政策更加有效;通货膨胀冲击下,实际利率在长期有所上升,但并未达到控制通货膨胀的效果,实际利率偏低阻碍了货币政策效果的发挥;人民币升值对产出增长具有较大的负面影响,对通货膨胀具有负向）中击,但由于油价上涨的原因,人民币升值并没有降低通货膨胀水平。     

中国经济的最优通货膨胀

制定一个适宜的长期通胀目标对于提高社会经济福利具有重要意义。本文构建了一个代表性的DSGE模型,用贝叶斯方法对模型进行了参数估计,并估算了在各种不同的货币政策规则下,中国经济所应选择的最优通胀目标。研究结果表明从短期看3%左右的通胀目标是最优的,而从中长期看低通胀目标(0.5%—1%)是最优的。本文的政策建议是盯住低通胀目标有利于长期社会经济福利,管住货币,看紧通胀仍应是中国央行货币政策制定的首要考量。     

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.

Inflation and output in the long and short run in Turkey

This paper firstly discusses the impact of inflation on real output in different theoretical models and then investigates this impact empirically in an economy facing persistent high inflation. We find some evidence of Sidrauski’s (Am Econ Rev 57:534–544, 1967) superneutrality of money for Turkey in the long run. However, it seems that inflation affects real output negatively in the short run. These results are more compatible with a class of utility functions in which real money balances and consumption are perfect complements as Asako (Econometrica 51(5):1593–1596, 1983) elucidates.

MODELLING DEMAND FOR BROAD MONEY IN AUSTRALIA*

The existence of a valid long‐run money demand function is still important for the conduct of monetary policy. It is argued that previous work on the demand for money in Australia has not been very satisfactory in a number of ways. This paper examines the long‐ and short‐run determinants of the demand for broad money employing the Johansen cointegration technique. Using quarterly data for the period 1976:3–2002:2, this paper finds, inter alia, that the demand for broad money is cointegrated with real income, the rate of return on 10‐year Treasury bonds, the cash rate and inflation. It appears that a disequilibrium in the demand for money can affect the efficacy of interest rate policy in the long run via its impact on future output growth and output gap.     

Determinants of bank credit in Pakistan: A supply side approach

This study empirically identifies the factors which explain the bank credit to the businesses in varying financial environments and emerging global challenges. With the major focus on supply side this study uses the ARDL econometric approach using annual data from the period 1971 to 2010 for Pakistan. The empirical results indicate that the foreign liabilities, domestic deposits, economic growth, exchange rate, and the monetary conditions are significantly associated with bank credit to the private sector in Pakistan, particularly in the long run. Whereas the inflation and money market rate does not affect the private credit. Moreover, in the short run the domestic deposit does not influence private credit. The results also infer that the financial health and liquidity of the banks play a significant and vital role in the determination of loan. Results also indicate that the long run relationship is stable and any disequilibrium formed in the short run will be temporary and get corrected over a period of time with a high speed of 53.5% per year. This study does not statistically distinguish the behavior of bank credit during non-financial (1971–1989) and financial reform periods (after 1990) in Pakistan.     

Assessing the effectiveness of monetary policy in Kenya: Evidence from a macroeconomic model

This paper examines the effectiveness of monetary policy in Kenya based on policy simulations from a structural macroeconometric model. The analysis is conducted using the policy rate, i.e. the central bank rate (CBR) and the cash reserve ratio (CRR) with respect to the interest rate and bank lending channels, respectively. The results indicate that whereas a change in the policy rate is effective in influencing short term rates, the long term lending rates respond marginally. Consequently, the transmission to the real economy and the overall impact on inflation is minimal. However, a change in CBR has a comparatively higher impact on inflation while a change in CRR has a relatively larger impact on aggregate demand. Enhancing the effectiveness of the CBR and strengthening of the interest rate channel have the potential of anchoring inflation expectations and boosting the effectiveness of monetary policy in Kenya.     

On the Effects of Inflation Shocks in a Small Open Economy

The effects of monetary policies remain always an important topic in macroeconomics. In the literature (closed and open economy), there is no theoretical as well as empirical consensus regarding the effects of monetary policies. In this paper we examine the real effects of inflation in an open economy. Australia is a classic example of a small open economy and is known to exercise inflation targeting. Using quarterly data from Australia and employing vector autoregressive (VAR) analysis, we provide evidence that inflation, both in the short and long run, negatively affects durable and non‐durable consumption and investment, and has a positive effect on the current account. Further, we show that consumption of durable goods is more sensitive than the consumption of non‐durables during the initial periods following inflationary shocks.     

A structural model of price and exchange rate dynamics in a small open economy

Conclusions A major result following from the analysis of ourstructural model of inflation under flexible exchange rates is that there is no such thing asstructural inflation in the long run. Long-run inflation rather becomes a purely monetary phenomenon if exchange rates are flexible and if on an international level functioning capital markets are postulated. While, in the light of the assumptions made in Part III, this finding is not nearly as paradoxical as it may appear at first sight, it can hardly be overemphasized considering the ongoing theoretical discussion and the empirical research on the Scandinavian approach to inflation and recalling that the Scandinavian model is basically intended to picture equilibrium dynamics.The results concerning equilibrium price and exchange rate dynamics also apply to the equilibriumlevels of prices and the exchange rate, i. e., the equilibrium price level depends exclusively on monetary factors while the equilibrium exchange rate is determined by a purchasing power parity element and the structural productivity gap component.Turning to the results of our analysis of disequilibrium dynamics, the overall picture does not change very much. Here the qualitative pattern of adjustment of both prices and the exchange rate is again completely independent of structural variables, but is exclusively determined by four adjustment coefficients. However, the particular quantitative values assumed by prices and the exchange rate during the adjustment process do indeed reflect the impact of the productivity gap.No conclusions can be derived from our model on the amount of time it takes to return to the neighbourhood of equilibrium once the economy has been subjected to some kind of external shock. A casual examination of post-1973 developments and especially the Swiss experience suggest, however, that in the case of a disturbance as, e. g., in the form of a monetary contraction (relative to the rest of the world), the economy may take so long to return to the neighbourhood of long-run equilibrium that the negative real consequences of the overvaluation of the domestic currency during the adjustment process provide a momentous rationale for short-run stabilization interventions in the foreign exchange market.We should like to thank Peter Bernholz and an anonymous referee for helpful comments on a previous version of this paper.     

Monetary policy and exchange rate dynamics in the Spanish economy

As the Spanish economy gets more integrated in international markets, the real exchange rate becomes a key determinant of the monetary transmission. In this paper we trace out the dynamic response of prices, output and the exchange rate following a monetary policy shock. We estimate a structural VAR model whose identification scheme is based on the long run properties common to a large class of models. The results suggest that a small model with efficient asset markets plus nominal inertia and long run monetary neutrality, captures the essential features of the monetary transmission mechanism in Spain. The interest rate shock is well identified and the exchange rate overshoots its long run value. There are no signs of liquidity puzzle nor of price puzzle or exchange rate puzzle either.     

NOMINAL WAGE INDEXATION,QUASI‐EQUILIBRIA AND REAL WAGE DYNAMICS

In contrast to the traditional static approach to indexation, this paper analyses the dynamic consequences for real wages of the mechanism that links nominal wages to inflation. Revisiting a contribution by Dehez and Fitoussi on macroeconomic fluctuations , I analyse a monetary overlapping generations small open economy in which full indexation is interpreted as the occurrence of a dynamic ‘quasi‐equilibrium’. In the suggested framework, the nominal wage is linked to the inflation rate by a specific indexation formula whose shape relies on unions' bargaining positions. Assuming a constant peg for the real interest rate and the superneutrality of money, I show that the economy has a unique long‐run quasi‐equilibrium allocation whose stability depends only on the behaviour of the monetary authority. Moreover, I show how the operating of a ‘wage‐aspiration effect’ might lead to the persistence of involuntary unemployment.     

Exchange Rate Determination: An Application of a Monetary Model for Brazil

The goal of this paper is to test a variant of the monetary exchange rate determination model, described by Obstfeld and Rogoff (1996), for the Brazilian economy in the recent period. The model starts with the Cagan (The Journal of Political Economy, 66(4):303–328, 1958) money demand, which is complemented by the hypotheses of purchase power parity (PPP) and uncovered interest parity (UIP). We used monthly data of exchange rate, GDP, interest rate for Brazil, and U.S. interest rate and inflation as proxies for international variables. We applied cointegration tests to identify a long run relationship among the variables. The estimated error correction model offers an exchange rate determination model in the short run. Due to potential endogeneity of some variables, GMM was applied to estimate a long-run model of exchange rate determination. The forecasting results of both estimatives were compared with a random walk approach. The results point to the existence of a long and short run equilibrium Real/dollar exchange rate using the structural model, which may be the achievement of this paper.     

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.     

Monetary Policy in Australia: The Conflict between Short-Term and Medium-Term Objectives

This article argues that the recent implementation of monetary policy in Australia has been dominated by the response to a large range of unanticipated shocks. In the process of trying to minimise the adverse effects of such shocks, considerable uncertainty has been created about likely outcomes in the medium term. This makes medium-term objectives harder to achieve. Taking the reduction of inflation as an example of an appropriate medium-term objective, simulations are presented using the Murphy model of the Australian economy. The simulations demonstrate that a tightening of monetary policy will reduce inflation more slowly if private agents believe that the tightening is unlikely to be sustained for long. Under uncertainty, monetary policy will have to be tighter and real GDP significantly lower to achieve a given reduction in inflation. A confingency rule of medium complexity is suggested as one way in which appropriate medium-term objectives might be achieved while allowing some flexibility to react to unexpected outcomes in the short run.     

Price Rigidities, Inflationary Finance and Long-run Growth*

The paper considers a monopolistically competitive intertemporally optimizing monetary economy featuring long-term growth. Inflation is generated through sluggish price-setting and contributes to budgetary finance through seignorage. This setup permits exploration of the interaction between inflation and growth in a tractable way. Superneutrality holds in the long but not the short run. The budget deficit fuels inflation with a hysteresis. Growth and inflation are negatively correlated in the long run, with causality running from the former to the latter, and positively correlated in the short run regardless of the origin of shocks. Price flexibility precipitates adjustment but appears also to destabilize output.     

Inflation bias and markup shocks in a LAMP model with strategic interaction of monetary and fiscal policy

This paper investigates the effects generated by limited asset market participation on optimal monetary and fiscal policy, where monetary and fiscal authorities are independent and play strategically. It shows that: (i) both the long run and the short run equilibrium require a departure from zero inflation rate; (ii) in response to a markup shock, fiscal policy becomes more aggressive as the fraction of liquidity constrained agents increases and price stability is no longer optimal even under Ramsey; (iii) overall, optimal discretionary policies imply welfare losses for Ricardians, while liquidity constrained consumers experience welfare gains with respect to Ramsey.
