This paper proposes forward convergence as a model refinement scheme for linear rational expectations (LRE) models and an associated no-bubble condition as a solution selection criterion. We relate these two concepts to determinacy and characterize the complete set of economically relevant...

This paper argues against determinacy as a guide to interpret rational expectations solutions, using an example in which a determinate solution exists but differs sharply in dynamic behavior from that implied by the model considered on a sector-by-sector basis.

Markov-switching rational expectations (MSRE) models can bring out fresh insights beyond what linear rational expectations models have done for macroeconomics, as noted and predicted by Davig and Leeper (2007) and Farmer, Waggoner and Zha (2009), among others. However, a lack of tractable...

Under reduced-form learning, agents are endowed with an aggregate model, and rational expectations are then replaced with subjective expectations. This paper demonstrates that the reduced-form learning approach may be arbitrary in that a particular representation of aggregate dynamics has...

A New-Keynesian macro-model is estimated accommodating regime-switching behavior in monetary policy and macro-shocks. A key to our estimation strategy is the use of survey-based expectations for inflation and output. Output and inflation shocks shift to the low volatility regime around 1985 and...

This article contributes to the Permanent Income Hypothesis (PIH) and excess consumption smoothness debate in the context of fractional integration. We show that the excess consumption smoothness result is a consequence of the quarterly data frequency commonly employed in the empirical work. In...
