ICAPM approach with currency risk

This article investigates international stock market integration in largest (based on nominal GDP and purchasing power parity GDP) four developed namely USA, EMU, Japan and UK and two Asian emerging namely China and India international stock markets over the period June 1994 to June 2009. To model stock market integration we estimate a dynamic version of international capital asset pricing model (CAPM) in the absence of purchasing power parity. Conditional variance is modeled via a multivariate GARCH specification. To investigate the evolution of integration overtime we estimate the CAPM in sub-periods. In addition, we connect our results to the timing of world financial crises. Our findings show that the stock markets tend to move in parallel after June of 2002, although from 2002 to 2006 there have not been crises events. These results, supports the increasing globalization and interdependence of both emerging and developed markets in the recent decade, reducing the benefits of portfolio diversification.
