This paper examines the degree to which the learning by doing externality [LBD] calls for an undervalued exchange rate, a policy suggested by recent empirical studies which concluded that mildly undervalued real exchange rate may enhance growth. We obtain mixed results. For an economy where LBD...

This paper deals with the design of optimal monetary policy and with the interaction between the optimal degrees of wage indexation and foreign exchange intervention. The model is governed by the characteristics of the stochastic shocks which affect the economy and by the information set that...

This paper develops an analytical framework for the analysis of targeting rules for monetary policy. We derive the optimal money supply rule and analyze the implications of other monetary rules including rules that target nominal GNP, the price level, the monetary growth rate and the...

The purpose of this paper is to determine whether a two-tier exchange rate regime is more effective than a fixed rate regime in increasing acountry's ability to pursue an independent monetary policy in the short run.The analysis compares adjustment to a monetary policy and to a devaluation in...

Consider a multi-sector economy subject to an exogenous demand shock that alters the equilibrium structure of relative prices. How should the structure of sectorial wages adjust in response to such a shock? This question is addressed in the context of a multi-sector model of an open-economy...

The volatility of the exchange rate under floating rates can be interpreted in terms of approaches that allow for short term price rigidity as well as in terms of models that consider the magnification effect of new information. This paper combines the two approaches into a unified...

The purpose of this paper is to explain deviations from PPP in an economy charaterived by a mononolistic competitive market structure in which pricing decisions incur costs. That lead producers to pre-set the price path for several periods. The paper derives an optimal pricing rule, including...

This paper develops a unified framework for the analysis of wage indexation and monetary policy in the presence of supply shocks. We first present simple formulae for the optimal wage indexation rule and for the optimal money supply rule. In order to set the stage for an evaluation of departures...

This paper analyzes the role of relative prices in the conduct of wage indexation and monetary policy in a small economy producing traded and non-traded goods under a flexible exchange rate regime. It is shown that the beneficial effect of using relative prices in addition to aggregate prices as...
