中文摘要

本研究應用兩階段條件機率分配計算一種新的壓力事件損失暴露測度值，此源於某一市埸的壓力事件可能對其他市埸造成兩階段式的衝擊。兩階段式的傳輸可能在外資扮演一個顯著性角色的經濟體中發生。 本文應用所導出的新測度值於台灣歷史資料，以測試兩階段傳輸假說。所得的歷史模擬結果顯示，新測度值可改進一般金融機構風險值計算中，壓力測試方法低估或高估投資組合損失的偏差。
英文摘要

In this paper we use the two-stage conditional probability distributions to compute a new loss exposure measure for stress events that may have two-stage sequential impacts on various markets. The price changes in two-stage transmission could possibly be found in economies where foreign indirect investment plays a prominent role in the domestic financial markets. We test the conjecture of two-stage transmission by applying the new technique to the historical data of Taiwan. The simulated results show that the proposed loss exposure measure improves upon the over- or under-estimation biases commonly found in stress testing conducted by financial institutions in their VaR calculations.
