This paper seeks to advance the discussion of monetary policy strategies in several ways. One involves a comparison of targets for nominal GNP and the price level, with emphasis on specificational robustness and implications for output variability. A second pertains to various “indicator”...

This paper examines the dynamics of the foreign exchange market. The first half addresses a number of key questions regarding the forecasts of future exchange rates made by market participants, by means of updated estimates using survey data. Here we follow most of the theoretical and empirical...

In this paper we develop and test a model of a utility maximizing representative agent operating in the Belgium-Luxembourg two-tier foreign exchange market. Our tests examine and fail to reject a risk neutral representative agent utility function. When we combine a risk neutral utility function...

The paper reviews recent theoretical and empirical developments in the analysis of informal currency markets in developing countries. The basic characteristics of these markets are highlighted, and alternative analytical models to explain them are discussed. The implications for exchange rate...

This paper constructs and analyzes an optimizing model of dual exchange markets which are incompletely separated owing to the presence of fraudulent cross transactions. The model is used to examine the implications of certain shocks, including devaluation. Devaluation first leads to the...

The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and...

The paper explores the relationship between trade policy and current accounts. The effect on the current account of a change in protection at home and then abroad is analyzed, assuming that the exchange rate floats. The “savings-and-investment approach” is used. It shows that there is no...

In most macroeconomic models, the substitutability between domestic and foreign goods is calibrated using aggregated data. This imposes homogeneous elasticities across goods, and the calibration is only valid under this assumption. If elasticities are heterogeneous, the aggregate...

In View of the continuation of substantial movements in exchange rate relationships among major currencies, the recent increase in protectionist pressures, and the disappointing performance of world trade, renewed concern has been expressed about the possible adverse effects of exchange rate...

How should possible policy reforms and projects be assessed when prices give misleading signals? Revenues and costs at market prices then give distorted measures of social gains and losses and our appraisal should use social opportunity costs, or correctly defined, shadow prices. We show how...
