Both in theory and practice, capital controls and dual exchange rate systems can be part of a country's optimal tax policy. We first show how a dual exchange rate system can be interpreted as a tax (or subsidy) on international capital income. We show that a dual exchange rate system, with...

This paper develops a graphical method to determine the optimal degree of central bank conservativeness in an open economy. Unlike Rogoff (1985), the upper and lower bounds of the interval containing the optimal degree of conservativeness are expressed in terms of the structural parameters of...

The U.S. economy appears to have experienced a pronounced shift toward higher productivity over the last five years or so. We wish to understand the implications of such shifts for the structure of optimal monetary policy rules in simple dynamic economies. Accordingly, we begin with a standard...

James B. Bullard and Eric Schaling study a simple, small dynamic economy which a policymaker is attempting to control with a Taylor-type monetary policy rule. The authors wish to understand the macroeconomic consequences of the policymaker’s decision to include the level of equity prices in...

There is a considerable academic literature on the relationship between Central Bank independence and inflation but the issue of Central Bank accountability and its effect of inflation performance has received very little attention. This paper looks at the issue of accountability in a simple...

In this paper we incorporate the term structure of interest rates into a standard inflation forecast targeting framework. Learning about the transmission process of monetary policy is introduced by having heterogeneous agents – ie central bank and private agents – who have different...

In this paper we analyse disinflation policy in two environments. In the first, the central bank has perfect knowledge, in the sense that it understands and observes the process by which private sector inflation expectations are generated; in the second, the central bank has to learn the private...

This paper examines the relationship between in‡ation and in‡ation expectations of analysts, business, and trade unions in South Africa during the inflation targeting (IT) regime. We consider inflation expectations based on the Bureau of Economic Research (BER) quarterly survey observed...

South Africa's 40 years of experience with capital controls on residents and non-residents (1961-2001) reads like a collection of examples of perverse unanticipated effects of legislation and regulation. We show that the presence of capital controls on residents and non-residents enabled the...
