In this paper, I develop a new identification method to solve the problem of simultaneous equations, based on heteroskedasticity of the structural shocks. I show that if the heteroskedasticity can be described as a two-regime process, then the system is just identified under relatively weak...

This paper reviews the empirical literature on international spillovers and contagion. Theoretical models of spillover and contagion imply that the reduced form observable variables suffer from two possible sources of bias: endogeneity and omitted variables. These econometric problems in...

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...
