In his seminal paper, starting from the premise that productivity is heterogeneous across firms, Melitz (2003) nicely accounts for the stylized fact that the level of individual productivity is key in determining the capability of a firm to export. In this paper we build a model along Melitz's...

Expectations play a crucial role in modern macroeconomic models. We replace the common assumption of rational expectations in a New Keynesian framework by the assumption that expectations are formed according to a heuristics switching model that has performed well in earlier work. We show how...

In this paper we develop and estimate a behavioral model of inflation dynamics with monopolistic competition, staggered price setting and heterogeneous firms. In our stylized framework there are two groups of price setters, fundamentalists and naive. Fundamentalists are forward-looking in the...
