CAN A RULE‐BASED MONETARY POLICY FRAMEWORK WORK IN A DEVELOPING COUNTRY? THE CASE OF YEMEN

Monetary policy in Yemen is largely rudimentary and ad hoc in nature. The Central Bank of Yemen's (CBY) approach has been based on discretionary targeting of broad money without any clear target to anchor inflation expectations. This paper argues in favor of a new formal monetary policy framework for Yemen emphasizing a proactive and rule‐based approach with a greater direct focus on price stability in the context of a flexible management of the exchange rate. Although, as in many developing countries, institutional capacity is a concern, adopting a more formal framework could impel the kind of changes that are required to strengthen the ability of the CBY in achieving low and stable rates of inflation over the medium term.     

Will the Sarb always Succeed in Fighting Inflation with Contractionary Policy?

The conventional view is that a monetary policy shock has both supply‐side and demand‐side effects, at least in the short run. Barth and Ramey show that the supply‐side effect of a monetary policy shock may be greater than the demand‐side effect. We argue that it is crucial for monetary authorities to understand whether an increase in expected future inflation is due to supply shocks or demand shocks before applying contractionary policy to forestall inflation. We estimate a standard New Keynesian dynamic stochastic general equilibrium model with the cost channel of monetary policy for the South African economy to show that whether the South African Reserve Bank should apply contractionary policy to fight inflation depends critically on the nature of the disturbance. If an increase in expected future inflation is mainly due to supply shocks, the South African Reserve Bank should not apply contractionary policy to fight inflation, as this would lead to a persistent increase in inflation and a greater loss in output. Our estimation results also show that with a moderate level of cost‐channel effect and nominal rigidities, a New Keynesian dynamic stochastic general equilibrium model with the cost channel of monetary policy is able to mimic the price puzzle produced by an estimated vector autoregressive model.     

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.     

LOUD AND CLEAR? CAN WE HEAR WHEN THE SARB SPEAKS?

Inflation targeting is a forward‐looking framework for monetary policy that has brought unprecedented transparency to the process of monetary policy. This paper aims to assess the degree to which the South African Reserve Bank's (SARB) Monetary Policy Committee (MPC) has, since the introduction of inflation targeting, successfully communicated to the public its policy analysis, and, in particular, the expected future policy changes. It follows international literature in constructing a numerical index that is used to reflect the information content of the SARB's communications, specifically the monetary policy statements that accompanied each of the MPC meetings since 2000. This method allows us to judge, systematically, the degree to which the MPC has communicated successfully, and the evolution of that success over the past nine years. We find evidence that the MPC has succeeded in signalling their likely future policy decision with consistency over this period.     

Causes of Inflation in China： Inflation Expectations

This paper argues that the main causes of inflation in China since the early 21st century are changes in the public's inflation expectations. The conventional wisdom, the quantity theory of money, may not be adequate to capture the relationship between price changes and money supply growth, as the economic system evolves and people's income and wealth grow. An examination of China's GDP deflator and broad money supply relative to nominal GDP shows that the relationship between the two series is relatively weak. A further examination of China's monthly CPI series over the period 2001–2010 reveals that the autoregressive models are a better fit than the moving average models, which suggests that the role of CPI expectations has been significant and important. Because of the importance of inflation expectations in CPI movement, we believe the Central Bank's monetary policy that targets CPI inflation should emphasize the use of policy instruments that have direct and strong communication links with the public. Quantitative measures would have their own use, but their effectiveness would be unlikely to match that of interest rate measures, especially from a short‐term perspective.     

The exchange rate and monetary conditions in the Euro area

The Exchange Rate and Monetary Conditions in the Euro Area. — Using information from a variety of sources, this paper suggests that the exchange rate will play an important role in the transmission of the impact of monetary policy on the real economy and inflation in the euro area. As a first approximation it would be reasonable to assume that an increase in the real 90-day interest rate of 100 basis points would have the same effect on demand two years later as a 3.5 percent fall in the real euro exchange rate. This implies that the euro area will tend to behave like a large open economy rather than a closed economy and hence that it would be helpful in informing monetary policy to construct a Monetary Conditions Index (MCI).     

A nonnormative theory of inflation and central bank independence

A Nonnormative Theory of Inflation and Central Bank Independence. — The authors study monetary policy under different central bank constitutions when the labor-market insiders set the minimal wage so that the outsiders are involuntarily unemployed. If the insiders are in the majority, the representative insider will be the median voter. The authors show that an independent central bank, if controlled by the median voter, does not produce a systematic inflation bias, albeit equilibrium employment is too low from a social welfare point of view. A dependent central bank, in contrast, is forced by the government to collect seigniorage and to take the government’s re-election prospects into account. The predictions of their theory are consistent with the evidence that central bank independence decreases average inflation and inflation variability, but does not affect employment variability.     

A STOCHASTIC ESTIMATION FRAMEWORK FOR COMPONENTS OF THE SOUTH AFRICAN CONSUMER PRICE INDEX

Under inflation targeting in South Africa, it is important to monitor and forecast changes in prices, not only for aggregate measures of the consumer price index, but also its underlying sub-components. Hypotheses about sectoral transmission of policy and shocks are often more specific than hypotheses about overall transmission. This study employs a stochastic framework to estimate richly specified equilibrium correction models, four-quarters-ahead, for the 10 sub-components of the first targeted measure of the consumer price index, CPIX. The stochastic trends are estimated by the Kalman filter, and interpreted as capturing structural breaks and institutional change, a frequent cause of forecast failure. The trends suggest the design of deterministic split trends for use in recursive forecasting models, towards more accurate overall inflation forecasting. This research also has practical use for monetary policy in allowing identification of sectoral sources of inflation.     

Inflation Targeting as a Coordination Device

The paper analyses inflation targeting when two independent policy authorities (a central bank and a National Government) have divergent preferences for the optimal policy mix. We demonstrate that the main advantage of inflation targeting, as a policy regime, is that it represents a simple proxy for full coordination between policy authorities. Inflation targeting therefore helps because it reduces the conflicts between fiscal and monetary policy, expecially where there are strong spillovers between the two policies. These results are then tested, and largely validated, in a simulation framework using a small open economy calibrated model.     

Inflation targeting in Indonesia, 1999–2012: an ex-post review

Around the end of 1999, Bank Indonesia (BI) adopted inflation targeting as part of its approach to monetary policy. This article reviews the experience up to 2012, examines BI's performance in hitting its inflation targets and considers certain broader indicators of success. Overall, inflation targeting in Indonesia has been a messy, evolutionary process, and BI's implementation record compares unfavourably with that of its peers. Yet Indonesia recorded a significant downward trend in inflation during this period and maintained strong economic growth. Also, almost all of its inflation-targeting arrangements are now in line with common international practice. Looking ahead, this article offers suggestions for sustaining progress in inflation targeting, such as setting more ambitious targets in the outer years and implementing strong policies to reduce inflation further, including after large administrative price shocks.     

Inflation Targeting and Relative Price Variability: What Difference Does Inflation Targeting Make?

This article studies the effects of inflation targeting (IT) on relative price variability (RPV) using a data set of twenty countries comprising both targeters and nontargeters. We find that a decline in mean inflation after IT adoption is not necessarily associated with a similar fall in RPV and that what matters most for the structural changes in RPV is the initial inflation regime prior to the adoption of IT rather than IT adoption itself. IT adoption impacts the shape of the underlying relationship between inflation and RPV in countries with initially high inflation rates, moving it from monotonic to the U‐shaped profile observed consistently for countries with low‐inflation regimes. The minimum point of this U‐shaped curve is indicative of the public's expectations of inflation and is very close to the announced target for inflation in most of the countries we study.
