Previous work with survey data on inflationary expectations casts doubt on the Rational Expectations Hypothesis. In this paper, we develop a model of expectation formation where agents form their forecasts of inflation by selecting a predictor function from a set of costly alternatives whereby...

This article considers the interaction of optimal monetary policy and agents' beliefs. We assume that agents choose their information acquisition rate by minimising a loss function that depends on expected forecast errors and information costs. "Endogenous inattention" is a Nash equilibrium in...

Sargent's (1999) model of inflation is amended to include real oil prices and used to study the impact of exogenous supply shocks on the inflation time-series. We analyse whether these shocks can trigger escape-like episodes. We consider unobserved permanent shocks to the natural rate of...
