New-Keynesian models are characterized by the presence of expectations as explanatory variables. To use these models for policy evaluation, the econometrician must estimate the parameters of expectation terms. Standard estimation methods have several drawbacks, including possible lack of...

The link between monetary policy and asset price movements has been of perennial interest to policy makers. In this Paper we consider the potential case for pre-emptive monetary restrictions when asset price reversals can have serious effects on real output. First, we provide some historical...

The inertia found in econometric estimates of interest rate rules is a continuing puzzle. Many reasons for it have been offered, though unsatisfactorily, and the issue remains open. In the empirical literature on interest rate rules, inertia in setting interest rates is typically modelled by...

Using a general-equilibrium simulation model featuring nominal rigidities and monopolistic competition in product and labour markets, this Paper estimates the macroeconomic benefits and international spillovers of an increase in competition. After calibrating the model to the euro area vs. the...

This Paper shows that price rigidity evolves in an economy populated by imperfectly rational agents who experiment with alternative rules of thumb. In the model, firms must set their prices in the face of aggregate shocks. The payoff depends on the level of aggregate demand, as well as on their...

Rational expectations are often used as a strong argument against policy activism, as they may undermine or neutralize the policymaker’s actions. Although this sometimes happens, rational expectations do not always imply policy invariance or ineffectiveness. In fact, in certain circumstances...

We develop an estimated model of the US economy in which agents form expectations by continually updating their beliefs regarding the behaviour of the economy and monetary policy. We explore the effects of policy-makers' misperceptions of the natural rate of unemployment during the late 1960s...

This survey essay considers how rational expectations have changed our evaluation of monetary policy. In the first section, various underpinnings of the "Phillips curve" relation between inflation and output are reviewed. All are concluded to be products of particular institutional set-ups whose...

This Paper evaluates alternative designs of indicator regimes for monetary policy in a small stochastic macromodel of the small open economy with rational expectations. The paper first derives methods for deriving optimal control rules and optimal simple feedback rules in rational expectations...

The potential instability of a fixed monetary rule combined with automatic fixed stabilisers is a well-established feature of closed economy IS/LM models with wealth effects and asset accumulation. This paper examines the stability issue in a general open economy macromodel with alternative...
