We investigate the extent to which misperceptions about the economy can become self-reinforcing and thereby contribute to time-varying macroeconomic dynamics. To do so, we build a New Keynesian model with long-horizon expectations and dynamic predictor selection. Because agents solve...

In this paper, we compare two approaches to modelling behaviour under non-rational expectations in a benchmark New Keynesian model. The ‘Euler equation' approach modifies the equations derived under the assumption of rational expectations by replacing the rational expectations operator with an...
