Growth Dynamics: The Myth of Economic Recovery [PDF]

American Economic Review, 2005
Using panel data for a large set of high-income, emerging market, developing, and transition countries, we find robust evidence that the large output loss from financial crises and some types of political crises is highly persistent. The results on financial crises are also highly robust to the assumption on exogeneity.
