We study the design of optimal monetary policy under uncertainty in a dynamic stochastic general equilibrium models. We use a Markov jump-linear-quadratic (MJLQ) approach to study policy design, approximating the uncertainty by different discrete modes in a Markov chain, and by taking...

A slanted-L curve is well-suited to represent the non-linearity of the celebrated Phillips curve. We show this using cross-country data of major industrialized economies since 2009, including the inflationary surge of the 2020s. At high unemployment rates, an increase in demand reduces...

This paper asks whether a textbook Phillips curve can explain the behavior of core inflation in the euro area. A critical feature of the analysis is that we measure core inflation with the weighted median of industry inflation rates, which is less volatile than the common measure of inflation...

Three large current account imbalances -- one deficit (the United States) and two surpluses (Japan and the Euro area) -- are subjected to a minimalist structural interpretation. Though simple, this interpretation enables us to assess how much of each of the imbalances require a real exchange...

In most European countries, the prevailing terms of employment, including the nominal wage, can only be changed by mutual consent. I show that this feature implies that workers have a strategic advantage in the wage negotiations when they try to prevent a cut in nominal wages. If inflation is so...

We provide evidence on the fit of the New Phillips Curve (NPQ for the Euro area over the period 1970-1998, and use it as a tool to compare the characteristics of European inflation dynamics with those observed in the U.S. We also analyze the factors underlying inflation inertia by examining the...

U.S. macroeconomic evidence shows a negative relation between the rate of change of wages and unemployment. In contrast, most theories of wage determination imply a negative relation between the level of wages and unemployment. In this paper, we ask whether one can reconcile the empirical...

We show that a fiscal expansion by the core economies of the euro area would have a large and positive impact on periphery GDP assuming that policy rates remain low for a prolonged period. Under our preferred model specification, an expansion of core government spending equal to one percent of...

We revisit time-variation in the Phillips curve, applying new Bayesian panel methods with breakpoints to US and European Union disaggregate data. Our approach allows us to accurately estimate both the number and timing of breaks in the Phillips curve. It further allows us to determine the...

We study a sequential experimentation model with endogenous feedback. Agents choose between a safe and risky action, the latter generating stochastic rewards. When making this choice, each agent is selfishly motivated (myopic). However, agents can disclose their experiences to a public record,...
