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.     

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.     

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.     

Learning about fundamentals: The widening of the French ERM bands in 1993

Learning about Fundamentals: The Widening of the French ERM Bands in 1993. — The authors incorporate a Bayesian learning model into a fairly general model of exchange rate determination in discrete time. The model is applied to the period following the widening of the French-German ERM bands in August 1993, in which a systematic underprediction of the franc can be observed until February 1994. A (substantial) part of these forecast errors can be mimicked by a Bayesian learning process. Simulations with our model show that, after the widening of the bands, agents, contrary to their initial expectations, gradually learned that the true process driving monetary conditions in France had not changed notably.     

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 DEMOCRATIC DEFICIT AND INFLATION TARGETING

There is widespread consensus that a goal dependent, but instrument independent central bank solves the democratic deficit. However, the standard solution to the democratic deficit risks reintroducing the biases of political control over monetary policy through the power of politicians to change the monetary policy rule. This paper considers the problem as an instance of the paradox of power in the sphere of monetary policy and proposes a solution drawing on criteria for the rule of law and the principles of constitutional economics. Finally a normative test of inflation targeting is proposed, again drawing on the constitutional economics literature.     

Aggregate price shocks and financial stability: the United Kingdom 1796-1999

This paper investigates aggregate price shocks on financial stability in the United Kingdom. We construct an annual index of UK financial conditions for 1790-1999 and use a dynamic probit model to estimate the effect of shocks on the index. We find evidence that price level shocks contributed significantly to financial instability during 1820-1931 and that inflation rate shocks contributed to instability during 1931-1999. While affecting the stability of the financial system, both the nature of aggregate price shocks and their impact depend on the existing monetary and financial regime.     

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.     

PROPOSALS FOR STRENGTHENING THE SARB'S INFLATION TARGETING REGIME

This paper proposes a set of criteria for efficient institutions derived form the New Institutional Economics literature and the IMF's Code of Good Practices on Transparency in Monetary and Financial Policie. These criteria are used to evaluate the institutional framework of South Africa's inflation targeting regime. A test for measuring the comprehensiveness of South Africa's inflation targeting regime is used to verify the results of the institutional evaluation. Finally, a matrix of proposed institutional reforms is constructed to address weaknesses identified by the institutional evaluation.
