Models of “contagion” rely on market imperfections to explain why adverse shocks in one asset market might be associated with asset sales in many unrelated markets. This paper demonstrates that contagion can be explained with basic portfolio theory without recourse to market imperfections....

There have been several episodes of financial market ""contagion"" in the 1990s. Is contagion driven by herd behavior? Does it reflect fundamental economic linkages between countries? Or are episodes of contagion driven by investor learning and risk reassessment about a select group of...

This paper tests for evidence of contagion between the financial markets of Thailand, Malaysia, Indonesia, Korea, and the Philippines. Cross-country correlations among currencies and sovereign spreads are found to increase significantly during the crisis period, whereas the equity market...

This paper investigates empirically the degree of international integration of industrial and emerging country equity markets. It analyzes two issues: first, the extent to which equity prices have tended to move similarly across countries and regions in the long run; and second, the strength of...

The entire difference between a mild downturn and a devastating crisis is the occurrence of sharp fire sales of domestic assets and possibly foreign exchange and the ensuing collapse in the balance sheets of both the financial and nonfinancial sector. Why and how do such crises materialize? And...

Several concepts of contagion are distinguished. It is argued that only models that admit of multiple equilibria are capable of producing true contagion. A simple balance of payments model is presented to illustrate that phenomenon, and some back-of-the-envelope calculations assess its relevance...

Over the past two decades, most emerging market economies witnessed two key developments. A marked process of financial integration with the rest of the world, arguably turning these economies more vulnerable to global financial shocks; and an improvement of macroeconomic fundamentals, helping...
