Entry and exit echoes

While aggregate data do not show the investment echoes predicted by vintage-capital models, echoes arise in rates of entry and exit of firms at the industry level. Moreover, industries where prices decline rapidly experience early ‘shakeouts’. The relation emerges naturally in a vintage-capital model in which exit of firms sometimes accompanies the replacement of their capital, and in which a shakeout is the first replacement ‘echo’ of the capital created when the industry is born.
