Financial stability is an important policy objective, since crises are associated with large economic, social and political costs. Promoting stability requires preventing 'sudden stops' in capital flows, which are events in which foreign financing abruptly disappears. This paper contributes to...

This paper analyzes the relevance of external factors in average quarterly GDP growth for 1990-2006 in the seven largest Latin American countries (LAC7). Modeling the relationship between LAC7 GDP and several external factors, it is found that those factors account for a significant share of...
