This paper describes an economy where incomplete information regarding the default penalty can result in an upward-sloping supply of credit.We evaluate the role of partial information and other related factors in determining the elasticity of supply of credit and the credit ceiling facing the...

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 purpose of this paper is to explain price and output dynamics in an open economy characterized by a monopolistic 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,...

This paper derives the dependency of optimal tariff and inflation tax on tax collection and enforcement costs. The analysis is done for a small, open economy. The existence of such costs can justify tariff and inflation tax policies as optimal revenue-raising devices. This paper suggests that...

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 studies the optimal use of distortive policies aimed at raising a given real revenue, in a general equilibrium framework in which lump-sum taxes are absent. The policies analyzed are an inflation tax,commercial policy, and an implicit tax on capital inflows implemented by capital...

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...

The purpose of this paper is to study analytically how the presence of transportation costs in a model of deviations from PPP affects the testing procedure of the PPP hypothesis The analysis shows that in the presence of transportation costs traditional regression analysis will tend to reject...

The purpose of this paper is to compare the behavior of an economy subject to labor contracts with an economy where the labor market clears in an auction manner. Such a comparison is intended to reveal the information content of real wages in a flexible economy. The analysis reveals two distinct...

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...
