Resumen de Extremal Dependence in International Output Growth: Tales from the Tails
Miguel de Carvalho, Antonio Rúa Vieites
This article explores the comovement of the economic activity of several OECD countries during periods of large negative and positive growth. Extremal dependence measures are here applied to assess the degree of cross-country tail dependence of output growth rates. Our main empirical findings are: (i) cross-country tail dependence is much stronger during periods of large negative growth, than during the ones of large positive growth; (ii) cross-country growth is asymptotically independent; (iii) cross-country tail dependence is considerably stronger than the one arising from a Gaussian dependence model. In addition, our results suggest that, among the typical determinants for explaining international output growth synchronization, only economic specialization similarity seems to play a role during such extreme periods.
