Optimal Monetary Policy Rules and Inflation Targets: Are Australia,Canada, and New Zealand Different from the U.S.?

Outwardly, the central banks of Australia, Canada, New Zealand, and the U.S. follow somewhat different approaches to controlling inflation. The U.S. does not explicitly target inflation while the other countries do. Canada and New Zealand have target bands for inflation while Australia has a point target. Results in this paper nevertheless find broad similarities in the monetary policies of these countries. Each can be described as having pursued optimal inflation targeting (explicit or implicit), with heavy interest rate smoothing, but perhaps placing little weight on output variability. We argue that interest rate smoothing is used to introduce gradualism into the response of monetary policy to inflation. We show that given heavy interest rate smoothing, a concern for output variability is redundant.

Monetary Aggregates Targeting,Inflation Targeting and Inflation Stabilization in Ghana

The central bank of Ghana (BoG) has operated monetary aggregates targeting and inflation targeting since the 1980s, to ensure enhanced output growth, low unemployment and stable, low inflation. Under inflation targeting, the inflation rate averaged 13.26 per cent per annum between 2007 and 2015, compared with 29.22 per cent per annum under monetary aggregates targeting. The relatively lower inflation rates notwithstanding, an average inflation rate of 13.2 per cent per annum is far above the medium‐term target of 8 per cent. This paper has examined the effectiveness of monetary aggregates targeting and inflation targeting in keeping inflation at moderate levels. The autoregressive distributed lag (ARDL) model was applied to the data covering the period 1970–2015. The results show that monetary targeting has steered inflation to moderate levels only in the short run while inflation targeting has maintained low inflation rates in both short run and long run. But neither regime has kept inflation at stable levels and within the target band, due to the sluggish transmission of broad money supply and prime rate changes to inflation. We implore the monetary authorities to strengthen the institutional setup for steering short‐term interest rates in Ghana. They should also enhance the BoG Act 2002 (Act 612), to develop secondary anchors and rules around output, money supply and fiscal deficit. Finally, the monetary policy committee should monetary policy credibility and transparency through strengthening its communication framework.     

Emigration from the United Kingdom to the United States,Canada and Australia/New Zealand, 1870–1913: Quantity and quality

This paper revisits the determinants of emigration from the United Kingdom to the United States, Canada and Australia/New Zealand from 1870 to 1913. In the absence of restrictive immigration policies, the flow of emigration to these destinations responded to economic shocks and trends. Emigrants to Australia and New Zealand were more skilled on average than those heading across the Atlantic, a feature that does not correspond well with skill differentials in the manner predicted by the Roy model. While assisted passages (subsidised fares) increased the volume of emigration to Australia and New Zealand they cannot account for its higher skill content.     

New Keynesian Explanations of Cyclical Movements in Aggregate Inflation and Regional Inflation Differentials

What determines the cyclical behavior of aggregate inflation and regional inflation differentials? The answer has strong implications for monetary policy and in Europe for the Stability and Growth Pact. In the United States, inflation rates move pro-cyclically, and across the Euro Area, inflation differentials are positively correlated with growth differentials. This suggests that demand shocks are the primary determinants of the cyclical behavior of aggregate inflation and regional inflation differentials. In this paper, we discuss New Keynesian explanations of these correlations, and we argue that demand shocks are either missing or inadequately modeled in the in typical New Keynesian model.     

Targeting Rules for an Open Economy

This study extends the formal analysis of inflation targeting monetary policy using the standard New Keynesian framework to a small open economy by adding inflation and output persistence as well as a direct exchange rate channel to domestic inflation. We find that output variability is lower under CPI inflation targeting than under domestic inflation targeting. However, CPI inflation results in higher variability of the real exchange rate than domestic inflation targeting. Output and the nominal interest rate are less volatile under flexible inflation targeting than under almost-strict inflation targeting. We also find that almost-strict domestic inflation targeting cannot completely insulate domestic inflation from foreign shocks due to a direct exchange rate channel. The model is calibrated to Canadian data.     

What to Aim for? The Choice of an Inflation Objective when Openness Matters

Inflation targeting countries generally define the inflation objective in terms of the consumer price index. Studies in the academic literature, however, reach conflicting conclusions concerning which measure of inflation a central bank should target in a small open economy. This paper examines the properties of domestic, CPI, and real-exchange-rate-adjusted (REX) inflation targeting. In one class of open economy New Keynesian models there is an isomorphism between optimal policy in an open versus closed economy. In the type of model we consider, where the real exchange rate appears in the Phillips curve, this isomorphism breaks down; openness matters. REX inflation targeting restores the isomorphism but this may not be desirable. Instead, under domestic and CPI inflation targeting the exchange rate channel can be exploited to enhance the effects of monetary policy. Our results indicate that CPI inflation targeting delivers price stability across the three inflation objectives and will be desirable to a central bank with a high aversion to inflation instability. CPI inflation targeting also does a better job of stabilizing the real exchange rate and interest rate which is an advantage from the standpoint of financial stability. REX inflation targeting does well in achieving output stability and has an advantage if demand shocks are predominant. In general, the choice of the inflation objective affects the trade-offs between policy goals and thus policy choices and outcomes.     

INFLATION TARGETING AND THE FISHER EFFECT IN SOUTH AFRICA: AN EMPIRICAL INVESTIGATION

The paper analyses the relationship between expected inflation and nominal interest rates during a period of inflation targeting in South Africa, i.e. from 2000 to 2005. Specifically, it investigates the Fisher hypothesis that nominal interest rates move one‐to‐one with expected inflation, leaving the real interest rate unaffected. The analysis distinguishes between a short‐run Fisher effect and a long‐run Fisher effect. Using cointegration and error correction models (for monthly data for the period April 2000 to July 2005), it was found that the short‐run Fisher hypothesis did not hold during the relevant period under the inflation targeting monetary policy framework in South Africa. This is attributed to a combination of the South African Reserve Bank's (SARB) control over short‐term interest rates and the effects of the monetary transmission mechanism. The long‐run Fisher hypothesis could not be confirmed in its strictest form: while changes in inflation expectations move in the same direction as the nominal long‐term interest rate. This suggests that monetary policy has an influence on the real long‐term interest rate, which has positive implications for general economic activity, thus confirming the credibility of the inflation targeting framework.     

SUPPORTING AN INFLATION TARGETING POLICY WITH THE MEASUREMENT OF INFLATION CREDIBILITY

Inflation targeting anchors inflation expectations, which are not within the sphere of control of the authorities, but can only be influenced over time by consistent policy. As public distrust of inflation figures will feed through to inflation expectations, this paper highlights pilot studies measuring the credibility of inflation in terms of an inflation credibility barometer. Despite initial discouraging results, the conclusion is that knowledge and information improve the credibility of inflation, but only one inflation rate (ideally the one used for inflation targeting purposes) should be communicated. Moreover, the rate used for targeting purposes should be specified with ease of communication in mind.     

The choice of inflation targeting—an empirical investigation

A growing number of countries have anchored their monetary policy to an explicit numerical rate or range of inflation since such an inflation targeting framework was first adopted by New Zealand in 1989. This paper empirically investigates economic structure and institutional factors associated with a country’s choice of inflation targeting using a dataset of 66 countries for the period of 1980–2000. It is found that a sound fiscal position is significantly and positively associated with the choice of inflation targeting framework; the central bank is more likely to adopt inflation targeting with greater financial depth; institutional capacity including central bank autonomy and flexible exchange rate regime is important for the choice of inflation targeting.

Central bank credibility and the expectations channel: evidence based on a new credibility index

This article investigates the relationship between central bank credibility and the volatility of the key monetary policy instrument. First, we propose a time-varying measure of central bank credibility based on the gap between inflation expectations and the official inflation target. While this new index addresses the main limitations of the existing indicators, it also appears particularly suited to assess the monetary experiences of a large sample of inflation-targeting emerging countries. Second, by means of EGARCH estimations, we formally prove the existence of a negative effect of credibility on the volatility of the short-term interest rate. In line with the expectations channel of monetary policy, the higher the credibility of the central bank, the lower the need to move its instruments to effectively fulfill its objective.     

The Impact of US Uncertainty Shocks on Small Open Economies

In this paper, we investigate the impact of US uncertainty shocks on GDP growth in nine small open economies: Australia, Canada, Denmark, Finland, Iceland, New Zealand, Norway, Sweden and the United Kingdom. We compare the impact of two types of shocks: i) stock market volatility shocks and ii) policy uncertainty shocks. Using quarterly data from 1986Q1 to 2016Q1, this issue is analysed using Bayesian VAR models. Our results suggest that policy uncertainty seems to matter more than stock market volatility. Stock market volatility shocks appear to robustly have significant effects on Danish GDP growth. Policy uncertainty shocks, on the other hand, reliably lowers GDP growth in all five Nordic countries in a statistically significant manner. Statistically significant effects of policy uncertainty shocks on the Anglo-Saxon countries in our sample are harder to establish and are, in our preferred specification, only found for the United Kingdom.     

Common Stocks and Inflation: An Empirical Analysis of G7 and BRICS

In an attempt to understand the relationship between stock returns and inflation, this study proposes testing the Fisher effect in two groups of countries, the G7 (Canada, France, Germany, Italy, Japan, United Kingdom and the United States) group of low inflation industrialized countries and the BRICS (Brazil, Russia, India, China, and South Africa) group of relatively high inflation emerging countries, to examine the extent to which a one-to-one movement of stock returns and inflation relates to the country’s inflation rate and consumer price index. By using cointegration and vector error correction models, the results show that there is evidence of a long-run positive relationship in both G7 and BRICS countries.

Goods Inflation,Asset Inflation,and the Greatest Peacetime Inflation in the US

In every episode of global monetary inflation originating in the Federal Reserve, we find both asset price inflation and goods inflation. The interrelationship between these two types of inflation depends both on cycle-specific factors and more general factors which transcend the cycle and stem from essential aspects of monetary disorder. The purpose of this article is to analyse the nature of this interrelationship and elaborate on the concepts of monetary disorder, goods inflation, and asset inflation. In today’s world of monetary systems where there is no stable demand for high-powered money (which itself is no longer a highly distinct asset) monetary disorder can be hard to recognize until quite late in the inflationary process. Asset price inflation now has a popular meaning quite different from the original found in Austrian business cycle theory. Two decades of widespread inflation targeting at around 2% per annum have encouraged us to ignore an old lesson. In a well-functioning capitalist economy under a sound money order, prices would fluctuate considerably upwards and downwards with a tendency to revert to the mean over the very long run. Finally the principles and hypotheses developed here are analysed in the laboratory of history, specifically for the greatest peacetime inflation in the U.S. (1963–80).     

CAN TUNISIA MOVE TO INFLATION TARGETING?

Inflation targeting has become an alternative monetary strategy that has been followed by many industrial and emerging countries. This study considers whether the adoption of inflation targeting would be relevant for Tunisia. More specifically, this paper aims at checking whether the necessary conditions for the successful implementation of such a strategy are fulfilled or not. It is found that fiscal dominance does not constitute the main hindrance to the adoption of inflation targeting. Other impediments have been identified, especially a weak financial system in general, the unsound and fragile banking system in particular, and the glaring lack of knowledge about the monetary transmission mechanism. Furthermore, it has been pointed out that if Tunisian monetary authorities continue to carry out the present exchange rate regime, namely, the constant real exchange rate rule, an inflation targeting regime will not be sufficient to properly contain the inflation pressures caused by demand shocks.     

Inflation targeting in India: A comparison with the multiple indicator approach

The empirical literature on identification and measurement of the impact of monetary policy shocks on the real side of the economy is fairly comprehensive for developed economies, but very limited for emerging and transition economies. In this study, we propose an identification scheme for a developing economy (taking India as a case study), which is able to capture the monetary transmission mechanism for that economy without giving rise to empirical anomalies. Using a VAR approach with recursive contemporaneous restrictions, we identify monetary policy shocks by modelling the reaction function of the central bank and structure of that economy. The effect of monetary policy shocks on the exchange rate and other macroeconomic variables is consistent with the predictions of a broad set of theoretical models. This set-up is used to build a hypothetical case of inflation targeting where the monetary policy instrument is set after assessing the current values of inflation only. This is in contrast with the ‘multiple indicator approach’ currently followed by the Reserve Bank of India (RBI). The results in this study suggest that the demand effects of interest rate are stronger than the exchange rate effects. There is also evidence of the mitigation of potential conflict between exchange rate and interest rate, one of main monetary policy dilemmas of the RBI in inflation targeting.     

Direct Inflation Targeting and Nominal Convergence: The Czech Case

This study analyses the impact of direct inflation targeting (DIT) on monetary policy credibility in the Czech Republic, as evidenced by asset prices. It examines the effect of changes in the two-week repo rate (the official interest rate) on short and long–term market interest rates. It assumes the asymmetry of information and the existence of a stationary stochastic equilibrium with full knowledge of authorities reaction function. We find that at short maturities, the coefficients for changes in the official repo rate are lower in the DIT period than in the pre-crisis period. This implies that the hypothesis of no increase in the transparency of monetary policy with the introduction of DIT can be rejected. We find that bond yields and interest rate swap rates with maturities of 5 years and longer did not react significantly to official interest rate decisions in the DIT period. This is consistent with the hypothesis that monetary policy was credible both before and after introduction of DIT.     

Revisiting the Exchange Rate Pass‐Through to Inflation in Africa’s Two Largest Economies: Nigeria and South Africa

This paper revisits the exchange rate pass‐through (ERPT) to inflation in Nigeria and South Africa by incorporating structural breaks and using time series variables, namely the consumer price index, nominal effective exchange rate, gross domestic product, and crude oil price. Based on the Maki cointegration test and a flexible estimation approach of the Autoregressive Distributed Lag (ARDL) model, our empirical evidence suggests that the long‐ and short‐run ERPT to inflation is complete for Nigeria, while for South Africa it is incomplete both in the long run and short run. This result indicates that prices are stickier in South Africa compared to Nigeria. The comparison between Nigeria and South Africa confirms the role of inflation targeting and central bank credibility on the ERPT. The results divulge further that output growth in Nigeria increases inflation in the long run while it is anti‐inflationary in the short run. For South Africa, the effect of output growth is negatively insignificant. In addition, the long‐run effect of oil price is negative and significant for Nigeria, while for South Africa the short‐run effect of oil price is positive and significant. Therefore, the findings of this paper will assist the monetary authorities to achieve monetary policy objectives.     

Credibility and monetary policy in a model with growth

We examine the implications for monetary policy design of includinglearning-by-doing effects in a macroeconomic model. We showthat an inflation bias arises because monetary surprises maybe exploited to maximise potential output by temporarily raisingthe rate of human capital accumulation. Our model also providesan alternative explanation for the empirical evidence linkinginflation and growth, where the causal link goes from slow growthto high inflation. Unlike traditional credibility models, aninflationary bias can persist even when the authorities do notwish to offset labour market distortions through monetary surpriseswhich undercut the median voter's income.
