本篇文章旨在探討外匯市場風險溢酬與兩國間的權益報酬之間的關聯性。以Chiang (1991)主張外匯市場的風險溢酬是與兩國間的股票市場之風險溢酬差異息息相關為架構，檢驗美國與印尼、韓國、馬來西亞、菲律賓、新加坡、台灣、泰國間的未拋補股價平價(Uncovered Equity Parity)條件是否成立，結果發現國際熱錢的效應，使得樣本新興國家的匯險溢酬與股市風險呈現正向關係。
我們主要利用OLS法、工具變數法及TSLS-GARCH (1,1)-X 三種方法來探討變數之間的關聯性。此外，為了更能準確的捕捉到外匯市場風險溢酬的特性，我們特別將兩國股市報酬與資本流量三個變數放入條件異質變異數方程式中，以檢驗因時而異的風險溢酬之存在性和波動特性，以及波動間之相關性等問題。實證結果發現此三個變數因子對條件變異數的確有各種顯著及不同的影響。

This paper investigates how the relative performance of the domestic and the foreign equity markets affect the excess returns of foreign exchange returns for seven Asian Emerging stock markets. In all cases, higher average returns appear to be associated with a higher level of volatility. Testing the relationship between exchange rate premiums and relative equity returns by using OLS method, we find that the exchange rates tend to appreciate when the corresponding equity markets rise, implying massive of international “hot money” has been flowing into these emerging capital market. Using instrumental variable method and TSLS-GARCH (1,1)-X model, the testing results show that the exchange rate premium are significantly correlated with economic fundamentals such as the relative equity premium between the domestic and foreign equity markets, and capital flows.
