Recently, a new class of macroeconomic business cycle models has emerged. Stochastic dynamic general equilibrium models with rational expectations originally employed by RBC researchers are combined with nominal rigidities and imperfect competition traditionally highlighted by New Keynesian...

This paper analyzes the period-to-period changes that occur in an optimizing monetary model with uncertainty and sticky prices. Money is incorporate in its role as a medium of exchange through a time-cost transactions techonolgy. Another important characteristic of the model is that both capital...

Curiously and in spite of its name, very few business cycle theories actually treat it as a cycle. Mainstream economics, for example, models all macroeconomic fluctuations as a function of exogenous forces. In their view, the economy remains at full employment indefinitely unless impacted by...

I start with income and wealth inequality data from the Congressional Budget Office (CBO) and Thomas Piketty, and propose approaches taken from science (for example, behavioral evolution theory,) that might be useful in explaining the data and forecasting future economic events. Using a modified...

La crise mondiale et celle, plus récente, dans la zone euro ont eu tendance à raccourcir l’horizon prévisionnel et décisionnel de nombreux agents économiques. Dans le même temps, les incertitudes (sur l’emploi, les retraites…) poussent plutôt à la remontée du taux d’épargne des...

A gravidade da crise económica actual tem justificado o apelo à instituição de uma nova ordem económica. De facto, parte daquela gravidade pode ser atribuída ao desconhecimento (ou à falta de reconhecimento) das relações que se estabelecem entre variáveis económicas chave, quer ao...

Overly optimistic expectations concerning productivity and consequent downward revisions are commonly viewed as a key determinant of U.S. investment during the boom-bust cycle of 1995–2003. This view is formalized and evaluated in a general equilibrium model with news shocks about future...

In this paper we develop a mixed frequency dynamic factor model featuring stochastic shifts in the volatility of both the latent common factor and the idiosyncratic components. We take a Bayesian perspective and derive a Gibbs sampler to obtain the posterior density of the model parameters. This...
