Discretionary policymakers cannot manage private-sector expectations and cannot co- ordinate the actions of future policymakers. As a consequence, expectations traps and coordination failures can occur and multiple equilibria can arise. To utilize the explanatory power of models with multiple...

Central banks pay close attention to inflation expectations. In standard models, however, inflation expectations are tied down by the assumption of rational expectations and should be of little independent interest to policy makers. In this paper, we relax the assumption of rational expectations...

This paper examines a recent shift in the dynamics of the term structure and interest rate risk. We first use standard … then estimate dynamic, affine, no-arbitrage models, which exhibit a significant difference in behavior that can be largely … attributed to changes over time in the pricing of risk associated with a “level” factor. Finally, we suggest a link between the …

The simplest tests of capital market efficiency are tests of the fair game model: conditional expected returns less the interest rate are equal to zero. The fair game model is thought to obtain only when markets are perfectly liquid. We show that this conjecture is false. In a model of the...
