Since the rational expectations revolution in macroeconomics, the subject has changed massively, adopting the principles behind the revolution and building on them in a spectacular way. In this accessible and informative book, the authors guide the student through what has become the conceptual...

A model of profits switches between four regimes with fixed probabilities; the rationally expected profits stream implies the stock market value. This efficient market model is not rejected by UK post-war time-series behaviour of either profits or the FTSE index.

The purpose in this letter is first to review briefly the empirical results on the relationship between real interest rates and real exchange rates; this empirical literature provides little support for the hypothesis of Roll that expected real interest rates are equal in general. Our second aim...

The Calvo contract Phillips Curve is widely indexed for general inflation, using either core inflation or other backward-looking formulae. Such a Phillips Curve implies a high and persistent degree of nominal rigidity. It is argued here that optimal indexation would by contrast use the rational...

We examine whether inflation targeting should be regarded as optimal. Targeting inflation implies (undesirably) that price level variance tends to infinity: we produce some evidence from both a representative agent model and a long-used forecasting model that, once an endogenous indexation...
