We characterize the optimal sequential choice of monetary policy in economies with either nominal or indexed debt. In a model where nominal debt is the only source of time inconsistency, the Markov-perfect equilibrium policy implies the progressive depletion of the outstanding stock of debt,...

This paper re-examines the issue of the credibility and sustainability of optimal policies derived from Pontryagin's Maximum Principle and generally regarded as time-inconsistent, in models with forward-looking rational expectations. Specifically, it considers the behaviour of such models in the...

This paper extends the work of Barro and Gordon (1983) to general linear models with rational expectations. We examine the question whether the optimal policy rule, i.e. the one that a government which could pre-commit itself would use, can be sustained as a consistent rule in the sense defined...

A classical equilibrium model is analysed of two interdependent monetary economies in which it is assumed that cash is the only asset, and which is characterized by perfect foresight, flexible exchange rates and imperfect substitution between home and foreign goods. The first-best optimum sets...

Is sovereign debt so different from corporate debt that there is no need for bankruptcy procedures to handle potential defaults? The basic tools of finance seem to confirm that, without water-tight sovereign immunity, creditors face a Prisoner’s Dilemma: litiginous creditors may be tempted to...

The effect of asymmetric information on monetary policy is investigated in the context of an overlapping wage contract model. Optimal rules with and without precommitment under full information are compared with the optimal rule without precommitment (i.e. the discretionary rule) under...

The paper investigates the sustainability of cooperative rules for the conduct of macroeconomic policy in a two-country world. The problem is set out as a supergame in which the threat strategy is to switch to a Nash non-cooperative equilibrium. A number of possible non-cooperative equilibria...

In this paper we solve for the optimal (Stackelberg) policy in a model of credibility and monetary policy developed by Cukierman and Meltzer. Unlike the (Nash) solution provided by Cukierman and Meltzer, the dynamic optimization problem facing the monetary authority in this case is not of a...

In a continuous time model of two symmetric open economies, with a floating exchange rate, we find that the pay-off to the policy coordination depends systematically on the heterogeneity of their inflation experience. While monetary policy coordination improves welfare when there is a common...
