High uncertainty is an inherent implication of the zero lower bound, while deflation is not because of inflationary pressure due to uncertainty about how debt will be stabilized. We show that policy uncertainty empirically accounts for the absence of deflation in the US economy. Announcing...

We develop methods to solve general equilibrium models in which forward-looking agents are subject to waves of pessimism, optimism, and uncertainty that turn out to critically affect macroeconomic outcomes. Agents in the model are fully rational, conduct Bayesian learning, and they know that...

We develop and estimate a general equilibrium model to quantitatively assess the effects and welfare implications of central bank transparency. Monetary policy can deviate from active inflation stabilization and agents conduct Bayesian learning about the nature of these deviations. Under...

We develop a theoretical framework to account for the observed instability of the link between inflation and fiscal imbalances across time and countries. Current policy makers behavior influences agents ' beliefs about the way debt will be stabilized. The standard policy mix consists of a...

We construct and estimate a model that features endogenous growth and technology diffusion. The spillover effects from research and development provide a link between business cycle fluctuations and long-term growth. Therefore, productivity growth is related to the state of the economy. Shocks...

The evolution of the U.S. economy over the last 55 years is examined through the lens of a micro-founded model that allows for changes in the behavior of the Federal Reserve and in the volatility of structural shocks. Agents are aware of the possibility of regime changes and their beliefs matter...

Under the Globalization Hypothesis for inflation, as globalization increases, global economic slack should progressively replace the domestic gap in driving inflation. In order to assess the empirical support for this theoretical prediction, we use impulse response functions of inflation to...

We reinterpret post World War II US economic history using an estimated microfounded model that allows for changes in the monetary/fiscal policy mix. We find that the fiscal authority was the leading authority in the ‘60s and the ‘70s. The appointment of Volcker marked a change in the...
