Rational Sunspots (with Guido Ascari and Hedibert F. Lopes), R&R at the American Economic Review
Abstract: The instability of macroeconomic variables is usually ruled out by rational expectations. We propose a generalization of the rational expectations framework to estimate possible temporary unstable paths. Our approach yields drifting parameters and stochastic volatility. The methodology allows the data to choose between different possible alternatives: determinacy, indeterminacy and instability. We apply our methodology to US inflation dynamics in the ‘70s through the lens of a simple New Keynesian model. When unstable RE paths are allowed, the data unambiguously select them to explain the stagflation period in the ‘70s.Thus, our methodology suggests that US inflation dynamics in the ‘70s is better described by unstable rational equilibrium paths.

Traditional and New Keynesian Dynamic Models for Potential Output and Inflation Rate, Rivista di Politica Economica, 2009, vol. 99(4). Winner of the 13th edition of the Angelo Costa Award
Abstract: This paper uses the Kalman filter to estimate potential output as a latent process. We estimate two Dynamic Linear Models, comparing the results obtained through a traditional and a New Keynesian model. We verify that the traditional measures of output gap, even if usually applied in the estimation of the New Keynesian Phillips curve, are not consistent with the theory. We propose a New Keynesian measure that overcomes this limit. We suggest it as an alternative to the use of marginal costs.
