We revisit the issue of multiplicity of equilibria when monetary policy is conducted with either the interest rate or the money supply as the sole instrument of policy. We show that in standard monetary models there are interest rate feedback rules, and also money supply rules, that implement a unique global equilibrium. This is a contribution to a literature that either concentrates on conditi...

economic development plans normally contain some policy objectives, especially for the most important macroeconomic variables. governments are expected to take best policies to achieve these objectives, although due to some structural or other impediments they may fail to touch the objectives. we have attempted to uncover the determinants of private consumption and investment as the objectives ...

In repeated games with di®erential information on one side, the labelling \general case" refers to games in which the action of the informed player is not known to the uninformed, who can only observe a signal which is the random outcome of his and his opponent's action. Here we consider the problem of minimizing regret (in the sense ̄rst formulated by Hannan [8]) when the information available...

We study interactions between monetary policy, which sets nominal interest rates, and …scal policy, which levies distortionary income taxes to …nance public goods, in a standard, stickyprice economy with monopolistic competition. Policymakers’inability to commit in advance to future policies gives rise to excessive in‡ation and excessive public spending, resulting in welfare losses equivalent t...

We study the monetary instrument problem in a model of optimal discretionary fiscal and monetary policy. The policy problem is cast as a dynamic game between the central bank, the fiscal authority, and the private sector. We show that, as long as there is a conflict of interest between the two policy-makers, the central bank’s monetary instrument choice critically affects the Markov-perfect Nas...

This paper characterises optimal monetary policy in an economy with endogenous …rm entry, a cash-in-advance constraint and preset wages. Firms must make pro…ts to cover entry costs; thus the markup on goods prices is e¢cient. However, because leisure is not priced at a markup, the consumption-leisure tradeo¤ is distorted. Consequently, the real wage, hours and production are suboptimally low. D...
