全球金融危機期間台灣標的股與美國存託憑證連動關係之結構性改變

Structural Breaks in Dynamic Relationships Between Taiwan’s Stock and ADRs During Global Financial Crisis

指導教授 : 陳婉淑

摘要


從美國本土次級房貸違約案,演變成全球的金融危機之世界金融市場連動,已是近年來最受關注之全球金融議題,本文以台灣標的股與美國存託憑證之連動關係為例,探討金融危機期間所造成之連動關係改變,進而探討風險管理的議題。過去文獻已證實標的股與美國存託憑證具有密切之連動關係,但此連動關係於2008-2009年金融危機中是否產生結構性之改變,可由本文提出之具有結構性改變之迴歸模式得到驗證,並且經由貝氏估計方法,觀察到台灣股票市場之五個標的股與其美國存託憑證之關係強度於金融風暴發生後,產生了結構性的改變,並且本研究方法也合理的估計出兩個改變之時間點,結果顯示兩個改變點為2007年金融危機開端與2009年金融危機期間。

並列摘要


During the financial crisis of 2008-2009, the effect of U.S. subprime mortgage has spread from the U.S. local market to the global market. We are interested to know the relationship between some technology stocks in Taiwan stock market and their American Depositary Receipt (ADRs) whether they have Granger Causality. An autoregression with exogenous variables and heteroskedastic dynamics model for daily stock returns subject to the presence of structural breaks is proposed. We identify the locations of structural breaks for technology stocks in Taiwan market during the financial crisis. It strongly supports that ADRs have significant impacts for technology stock returns. We find two structural breaks during the financial crisis .
