This paper presents a cash-in-advance framework, with variable income velocity, where the domestic effects, as well as the international transmission, of financial innovation can be analyzed. In particular, the discussion emphasizes the role of currency substitution and of cross-border transfers...

The choice of assigning monetary or fiscal policy to external balance is complicated when the authorities are concerned with both the current account balance and the exchange rate. A strategy of using monetary policy to control the current account via the exchange rate may fail, because the...

This paper discusses the scope, methods, and effects of international coordination of economic policies. In analyzing the scope for and of coordination, the paper addresses the rationale for coordination, barriers to coordination, the range and specificivity of policies to be coordinated, and...

This paper constructs and analyzes an optimizing model of a highly-indebted small open economy. An important innovation in the model is the incorporation of sovereign risk through the specification of an upward-sloping foreign debt supply function. The model is used to examine the interaction...

This paper analyzes the main conceptual issues that arise in assessing external sustainability with a view toward developing operational criteria for the purposes of multilateral surveillance. The main contribution of the analysis is to show how conditional forecasts of external imbalance may be...

The introduction of a new currency has often occurred as part of a program to fight hyperinflation. In this context, non-uniform conversion rates for different types of assets and liabilities have been used as a means of reducing an initial “excess” stock of liquidity. The paper examines the...

The observation that collection lags combine with inflation to erode fiscal revenues has long been a strong argument against seigniorage (Tanzi (1978)). However, with the exception of Dixit (1991), who used a general equilibrium model to reject this argument, the optimal tax literature has not...

The paper proposes a new welfare-based measure to evaluate the distributive effects of public programs. The proposed measure differs from traditional approaches in two important ways: first, it is based on life-cycle considerations, since most public expenditure programs have an intertemporal...

In designing policy measures, including possible social safety nets, targeted to the poor, it is important to fully understand the efficiency implications of these measures. There is abundant macroeconomic literature on their negative effects on the poor’s work effort. The literature, however,...

We survey the literature on the two main views of exchange rate determination that have evolved since the early 1970s: the monetary approach to the exchange rate (in flex-price, sticky-price and real interest differential formulations) and the portfolio balance approach. We then go on to discuss...
