| Tiivistelmä: | The authors introduce firm heterogeneity into the standard monopolistically competitive real business cycle model. The funfamental equilibrium path is derived and the time-series properties of aggregate GDP are studied analytically. Although firms' productivities are subject to temporary shocks, the aggregate process displays a novel form of nonlinearity and long memory which has not been built into the model at the outset. This aggregate GDP turns out to have very different properties from log-linear time-series models such as auto-regressive models and their extensions. It displays very strong persistence, which ends abruptly with a sudden change of tendency, giving its autocorrelation function an S-shape. |
