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 implications of uncertain policy preferences for the targeting and contracting approaches to monetary policy are investigated. It is shown that, in the presence of uncertain preferences, a linear incentive contract in the sense of Walsh performs better than an explicit inflation target as...

This paper examines the relationship between inflation and inflation 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 from...
