I develop a toolbox to analyze the properties of multivariate Markov-switching models. I first derive analytical formulas for the evolution of first and second moments, taking into account the possibility of regime changes. The formulas are then used to characterize the evolution of expectations...

While high uncertainty is an inherent implication of entering the zero lower bound, deflation is not, because agents are likely to be uncertain about the way policy makers will deal with the large stock of debt arising from a severe recession. We draw this conclusion based on a standard...

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 conduct of...

Using a general-equilibrium simulation model featuring nominal rigidities and monopolistic competition in product and labour markets, this Paper estimates the macroeconomic benefits and international spillovers of an increase in competition. After calibrating the model to the euro area vs. the...

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

This Paper proposes a markedly different transmission from monetary policy to the macroeconomy, focusing on how policy changes nominal inertia in the Phillips curve. Using recent theoretical developments, we examine the properties of a small, estimated US monetary model distinguishing four...
