Contagion in Latin America: Definitions, Measurement, and Policy Implications
NBER Working Paper No. 7885
This paper analyzes bond and stock markets in Latin America and uses these patterns to investigate whether contagion occurred in the 1990's. It defines shift-contagion' as a significant increase in cross-market linkages after a shock to one country or region. Several coin-toss examples and a simple model show that the standard tests for contagion are biased due to the presence of heteroscedasticity, endogeneity, and omitted-variable bias. Recent empirical work which addresses these problems finds little evidence of shift-contagion during a range of crisis periods. Instead, this work argues that many countries are highly interdependent' in all states of the world and the strong cross-country linkages which exist after a crisis are not significantly different than those during more stable periods. These findings have a number of implications for Latin America.
