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.     

ESTIMATING MONETARY POLICY RULES FOR SOUTH AFRICA

The paper combines the estimation of the Monetary Conditions Index (MCI) with the theoretic modelling of optimal monetary policy in South Africa. The idea that monetary policy is not only interested in optimal monetary conditions but also in external stability, provides the basis for the analysis. The paper introduces the concept of the MCI and estimates the relative influence of interest rates and exchange rates on the output gap. The estimated weights are 1.9:1. This estimation results is used to specify operating target rules for South African monetary policy.     

Did the underlying behaviour of inflation change in the 1980s? A study of 17 countries

Did the Underlying Behaviour of Inflation Change in the 1980s? A Study of 17 Countries. - Have the ERM member countries experienced a regime change to a lower degree of persistence for inflation in the 1980s compared to the 1970s? Some results give the impression that deflationary policies associated with ERM membership may have reduced the mean level of inflation, but did not reduce the persistence parameter over the last decade. However, other results show that the persistence parameter does decline for a majority of ERM members. Surprisingly, the results also show stronger evidence of a fall in inflation persistence for some non-ERM countries who adopted a strong anti-inflationary stance over the same period.     

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.     

INTERNATIONAL LESSONS FOR THE PROPERTY PRICE BOOM IN SOUTH AFRICA

South Africa appears to share some of the characteristics (property price boom, easing of monetary policy, strong domestic demand growth) of asset price booms in industrial countries that were followed by a period of weak growth. The international experience suggests that a number of practical obstacles need to be overcome before a more proactive role for monetary policy is warranted. However, a larger variety of available mortgage contracts, including longer‐term fixed‐rate contracts, should allow for a more efficient allocation of interest rate risks. Also, a more systematic nationwide collection of property price data, including data on commercial property price developments, would provide a more representative basis for analysis.     

Too Many Cooks? Committees in Monetary Policy

How many people should decide monetary policy? In this article, we take an empirical perspective on this issue and analyze the relationship between the number of monetary policy decision makers and monetary policy outcomes. Using a new data set that characterizes central bank monetary policy committees (MPCs) in more than 30 countries from 1960 through 2006, we find a U‐shaped relationship between MPC size and inflation; our results suggest that the lowest level of inflation is reached at MPCs with an intermediate size of about five to nine members. Similar results are obtained for inflation variability. Other MPC characteristics also matter for monetary policy outcomes, though to a smaller degree. For instance, the membership composition of the MPC as well as the frequency of MPC membership turnover appears to affect economic variables.     

ON INFLATION

There is currently much more common sense in the South African inflation debate than a few decades ago. In particular, the South African Reserve Bank exhibits a pragmatic, eclectic approach to inflation (as reflected in its bi‐annual Monetary Policy Reports). This is in stark contrast to the narrow, monetarist‐type thinking that tended to dominate during the 1980s. This paper is an attempt to contribute to the debate by highlighting a few issues, including the widespread substitution of the CPI by the CPIX, the fact that inflation is a process, the need to combat inflation, the causes of the decline in inflation in South Africa and the essential features of an inflation‐targeting framework for monetary policy.     

P-Star as a link between money and prices in Germany

P-Star as a Link between Money and Prices in Germany. — The equilibrium price levelP-Star is defined as money per unit of potential output at equilibrium velocity. Deviations betweenP-Star and the actual price level (price gap) serve as an indicator of future price movements. To measure equilibrium velocity and to take into account its downward trend in Germany, a long-run money demand function is integrated into theP-Star approach. According to the empirical results, the constructed measure ofP-Star provides a stable link between M3 and the price level. However, comparable evidence could not be established for Ml and M2.     

Financial repression, money growth, and seignorage: The Polish experience

Financial Repression, Money Growth and Seignorage: The Polish Experience. — A small analytical framework is developed to analyze the relation between reserve requirements, base money growth and seignorage revenues. From the analysis, the authors can derive of steady-state seignorage revenues as a function of the rate of money growth and the intensity of financial repression. The framework is applied to the case of Poland that has undertaken a rapid transition to a market economy and implemented a substantial financial sector reform. The process of financial sector reform in Poland is discussed and estimates of the currency demand and deposit demand functions are undertaken to derive the seignorage Laffer curve.
