Recent research has found that the dynamic properties of the New Keynesian model can be very different when the nominal interest rate is zero. Improvements in technology and reductions in the labor tax rate lower economic activity, and the size of the government purchase output multiplier can be...

The paper examines how the long-run inflation-unemployment tradeoff depends on the degree to which wage-price decisions are backward- versus forward-looking. When economic agents, facing time-contingent, staggered nominal contracts, have a positive rate of time preference, the current wage and...

This paper takes a new look at the long-run dynamics of inflation and unemployment in response to permanent changes in the growth rate of the money supply. We examine the Phillips curve from the perspective of what we call "frictional growth," i.e. the interaction between money growth and...

This paper contributes to the policy evaluation literature by developing new strategies to study alternative policy rules. We compare optimal rules to simple rules within canonical monetary policy models. In our context, an optimal rule represents the solution to an intertemporal optimization...

Using randomized control trials (RCT) applied over time in different countries, we study how the economic environment affects how agents learn from new information. We show that as inflation has risen in developed economies, both households and firms have become more attentive and informed about...

We explore the role of real wage dynamics in a New Keynesian business cycle model with search and matching frictions in the labor market. Both job creation and destruction are endogenous. We show that the model generates counterfactual inflation and labor market dynamics. In particular, it fails...

This paper studies the effect of mandated severance pay in a matching model featuring wage rigidity for ongoing, but not new, matches. Mandated severance pay matters only if binding real wage rigidities imply inefficient separation under employment at will. In such a case, large enough severance...

We demonstrate the possibility of indeterminacy and non-existence of equilibrium dynamics in a standard business cycle model with search and matching frictions in the labor market. Our results arise for empirically plausible parametrizations and do not rely upon a mechanism such as increasing...
