Extending recent theoretical contributions on sources of inflation inertia, we argue that monetary uncertainty accounts for sluggish expectations adjustment to nominal disturbances. Estimating a model in which rational individuals learn over time about shifts in U.S. monetary policy and the...

The Taylor Principle is often used to explain macroeconomic stability (see, e.g., Clarida et al. 2000). The reason is that this simple principle guarantees determinacy, i.e., local uniqueness of rational expectations equilibrium, in many New Keynesian models. However, analyses of determinacy are...

In the presence of firm-specific capital the Taylor principle can generate multiple equilibria. Sveen and Weinke (2005b) obtain that result in the context of a Calvo-tyle sticky price model. One potential criticism is that the price stickiness which is needed for our theoretical result to be...

With sticky prices, optimizing agents and money in the utility function, I derive the exact analytical solution for optimal monetary policy given a zero lower bound (ZLB) on the interest rate. The Phillips curve is Neo-Classical, and the ZLB is then not a constraint on optimal policy. Optimal...
