A fundamentals-based monetary policy rule, which would be the optimal monetary policy without commitment when private agents have perfectly rational expectations, is unstable if in fact these agents follow standard adaptive learning rules. This problem can be overcome if private expectations are...

We consider a simple general equilibrium model for the determination of asset prices together with full equilibria in the commodity and money markets. In this way portfolio aspects are introduced into a dynamic macro model which has many features from growth theory. Money holdings are modelled...

Commitment in monetary policy leads to equilibria that are superior to those from optimal discretionary policies. A number of interest rate reaction functions and instrument rules have been proposed to implement or approximate commitment policy. We assess these optimal reaction functions and...

We review the recent work on interest rate setting, which emphasizes the desirability of designing policy to ensure stability under learning. Appropriately designed expectations-based rules can yield optimal rational expectations equilibria that are both determinate and stable under learning....

Monetary policy is sometimes formulated in terms of a target level of inflation, a fixed time horizon and a constant interest rate that is anticipated to achieve the target at the specified horizon. These requirements lead to constant interest rate (CIR) instrument rules. Using the standard New...

We consider the impact of anticipated policy changes when agents form expectations using adaptive learning rather than rational expectations. To model this we assume that agents combine limited structural knowledge with a standard adaptive learning rule. We analyze these issues using two...

Inflation and financing of public expenditure by are analysed in an OLG model where the deficit is constrained to be less than a given fraction of intergenerational savings. Even if there may be multiplicity of steady-state equilibria, we show that, with such a constraint, the dynamics with...

We investigate both the rational explosive inflation paths studied by McCallum (2001), and the classification of fiscal and monetary policies proposed by Leeper (1991), for stability under learning of the rational expectations equilibria (REE). Our first result is that the fiscalist REE in the...

In this paper we develop a stochastic monetary growth model with exogenous productivity shocks to consider the effects of changes in the financing structure of government deficits on the key variables of the economy. We study how the presence of supply-side uncertainty affects the equilibrium of...

This paper shows that the Ricardian Equivalence proposition can continue to hold when expectations are not rational and are instead formed using adaptive learning rules. In temporary equilibrium, with given expectations, Ricardian Equivalence holds under the standard conditions for its validity...
