外資進入與金融風暴對於亞洲各國本土銀行業績效表現之影響 / The Effects of Foreign Bank Penetration and Financial Crisis

劉信芝, Liu, Hsin Chih Unknown Date (has links)
本文研究外資進入與亞洲融風暴對於本土銀行業的影響,在所選取的樣本中,我們發現國際化會提升銀行的獲利但不見得改善營運的效率性與穩定性。實証結果也不支持亞洲金融風暴對於亞洲銀行業有顯著影響的假說。同時發現市場的集中程度對於銀行業的獲利有些微影響,主要是關於銀行的訂價能力。最後,就所選取的十一個亞洲國家中討論,本文顯示在樣本時間點內,外資進入本土市場設立分行對於本土的效率性與穩定性的影響並不顯著。 / This research examines the effect of foreign banks penetration and financial crisis on the banking sectors in Asian countries. We find that internationalization improves the profitability of banks in our sample countries, but not necessarily improve their operational efficiency and financial stability. Our empirical results do not support the hypothesis that Asia Financial Crisis has a significant impact on Asian banking sectors. We also show that, bank concentration has little effect on the profitability of banks, and it was related to the pricing ability of banks. Lastly, our research shows that there is insignificant effect of foreign bank penetration on the efficiency and stability over these eleven Asian countries during our sample period.

匯率危機預警模型 : 東亞地區實證研究

蔡蘭馨, Tsai, Lan-Shin Unknown Date (has links)
1997年亞洲匯率危機的發生,引發學者對於危機發生原因的論戰。對於亞洲匯率危機發生的國家而言,究竟那些匯率危機理論具有解釋能力?又匯率危機是否是可以透過基本面的指標來預測的?假使可以效力又是如何?本文中為了回答這些問題,於是使用東亞六國包含印尼、韓國、馬來西亞、菲律賓、新加坡、泰國六個開發中國家1971-1998年的收據資料,並運用Probit的計量模型來進行實證研究。 本文實證結果發現,在匯率危機理論的解釋上,第一代匯率危機理論的論述,並不足以完全解釋東亞地區的發展中國家匯率危險的發生,必須再加上第二代的匯率危機理論的論述,才能完整找出東亞發展中國家匯率危機發生的決定因素。再者,在東亞地區發展中國家的匯率危機發生前,其基本面情況的確是程現亞化的趨勢。但是基本面惡化程度,並不足以單獨決定匯率危機的發生,必預加入除了基本面惡化程度,並不足以單獨決定匯率危機的發生,必須加入除了基本面以外,其它會影響投資人的行為和預期因素,如市場資訊不完全而造成群眾的盲從效果以及跨國的漫延效果......等等,綜合起來最後才會導致投機性攻擊而引發危機。換句話說,當政府在進行施政決策或者是投資人在進行經濟決策時,基本面因素或許不是政府或投資人唯一的考量,但卻是重要的考量之一。 另外,針對東亞地區匯率危機是否是可以預警以及預警效力如何的問題。經由實證結果,我們認為答案是肯定的,不論是從樣本內或樣本外來看這組解釋變數的指標的預測效力,都有超過百分之七十的預測水準。

亞洲金融風暴對東亞國家效率及生產力分析–資料包絡分析法之應用

潘思翰, Pan, Zsu-han Unknown Date (has links)
摘要 1980年代至90年代初期,東亞各國成為全球經濟重要的發展區域之一,泰國、馬來西亞、印尼、菲律賓等繼亞洲四小龍之後成為亞洲地區成長迅速的新興開發中國家。然而,自1995年起,東南亞各國經濟開始出現衰退現象,1997年7月泰國更出現泰銖貶值,匯價劇跌,造成泰國股市的崩盤,傳染性的匯率貶值壓力延伸至菲律賓、馬來西亞、印尼與新加坡,甚至連東北亞的韓國,日本、台灣與香港也受波及,使得整個東亞地區幾乎都遭受到金融風暴的衝擊。 因此本研究針對1984至2002年的東亞國家,採用資料包絡分析法探討亞洲金融風暴對東亞各國效率的影響,利用Malmquist指數計算分析生產力變動的來源,以研究東亞各國在歷經金融風暴後如何調整其生產力及效率。 本研究依東亞各國受金融風暴影響的程度分為金融風暴國以及非金融風暴國兩大群組,實證結果顯示,東亞地區國家之整體技術效率值以及純技術效率值於金融風暴發生後有提升的現象,相較於金融風暴國於風暴前後之整體技術效率值以及生產力變動有顯著差異,非金融風暴國則未發生此一現象。本研究利用國內固定資本形成毛額作為投入要素與實質國內生產毛額作為產出項所構成的效率前緣曲線圖,分析解釋前述現象,發現金融風暴國在風暴前確實有投資過剩的問題,風暴後金融風暴國效率的提升來自於調整其生產規模、減少不當投資。 此外,本研究發現中國大陸的生產力在金融風暴後有逐年衰退的趨勢,其主要原因是來自於規模變動的不利影響,意味著中國大陸在展現高度經濟成長的同時,似乎已產生供給過剩的現象,是否會為日後的經濟發展帶來隱憂,甚至成為二次亞洲金融風暴的起源,值得注意。 / Abstract From the1980s to early 1990s, East Asia became one of the most important areas in developing the global economy. Thailand, Malaysia, Indonesia, and Philippine’s economy grew up fast and became the newly developing country following the Four little Dragons in Asia. However, since 1995, the economy of various countries in Southeast Asia began to decline. In July 1997 Thailand’s Thai Baht and exchange rate depreciated dramatically and crash of the Thai stock market. Then the Tai Baht currency depreciation rapidly spread to Philippine, Malaysia, Indonesia and Singapore; even South Korea, Japan, Taiwan and Hong Kong were involved in the crisis. As a result, the whole East Asia nearly all suffered this financial storm. Today, most of Asian countries are recovered from the Asia crisis. In order to analyze how East Asian countries to overcome the Asian financial crisis and adjust their productivity and efficiency, this study uses a panel data of 15 East Asian countries through 1984 to 2002 to apply data envelopment analysis (DEA) to assess the effects of the Asia financial crisis and measure the Malmquist productivity index to analyze the sources of the change in efficiency. The study breaks down the East Asian countries into two groups, Asian-crisis countries and non-Asian-crisis countries, depending on the extent to which they were affected by the Asian financial crisis. The major findings of this paper are as follows. The full samples denote that after crisis era the overall technical efficiency and the pure technical efficiency are higher than that of before crisis era. The further analysis demonstrates that such phenomenon only can be found in Asian-crisis group. This study constructs a two dimensions efficiency frontier curve graph by using gross fixed capital formation and gross domestic product as input and output proxy to analyze the efficiency change to help to explain the above phenomenon. The frontier efficiency curves find that the Asian-crisis countries indeed have over investment problem before the crisis, and the improvement of efficiencies after crisis is due to successful downsizing, such as reducing production scale and improper investments. In addition, this study illustrates that the productivity change in China has a tendency of declining over the last couple of years. The main reason comes from the unfavorable change in scale efficiency. The high economic growth accompanies over supply in China which reveals the similar phenomenon in Asia-crisis countries before the crisis. Therefore, it is worth to take a notice that whether the growth phenomenon in China becomes the source of the second Asian financial crisis in the future.

股市價量關係的分量迴歸分析 / A Quantile Regression Analysis of Return-Volume Relations in the Stock Markets

莊家彰, Chuang, Chia-Chang Unknown Date (has links)
第一章 台灣與美國股市價量關係的分量迴歸分析 摘要 本文利用分量迴歸來觀察台灣和美國股市報酬率和成交量的價量關係。實證結果發現兩地股市的價量關係截然不同。台灣股市的報酬率與成交量之間具有正向關係,呈現「價量齊揚」和「價跌量縮」的現象,而前者效果通常較顯著;但報酬率接近最大漲幅限制時,報酬率與成交量之間並無顯著關係,報酬率接近最大跌幅限制時,「價跌量縮」的現象甚至更強。相對於台灣,美國股市的報酬率與成交量則出現「價量齊揚」與「價量背離」互相對稱的 “V” 字關係。就實證方法而言,傳統以 OLS 方法估計的迴歸模型並無法得到上述的實證結果。進一步的分析顯示,融券成數的高低以及平盤以下不得放空等規定都是造成台灣股市出現「價跌量縮」的可能原因。 第二章 股市價量關係的分量迴歸分析 (二) 摘要 本章利用分量迴歸觀察包括台灣在內的亞洲新興工業國家與成熟股市的價量關係。實證結果顯示,亞洲新興工業國家和日本股市「價量齊揚」的效果較強,其中香港、南韓和新加坡呈現較弱的「價量背離」現象,因此價量之間有不對稱的 “V” 字關係;而日本股市則呈現「價跌量縮」,與第一章分析的台灣股市價量關係相似。在成熟股市的價量關係中,英國金融時報指數、美國道瓊工業指數和德國股價指數皆呈現對稱的 “V” 字關係,與美國US指數的價量關係相似。亞洲地區的國家在1997下半年到1998上半年普遍經歷了一場金融風暴,本文進一步的分析發現在這場風暴期間,亞洲地區除了台灣以外,日本、香港、南韓與新加坡都出現較強的「價量齊揚」與「價量背離」,這種現象可能肇因於投資人認為風暴期間的股價報酬率風險較高,遂使得股價報酬率對成交量的反應較為敏銳。相對而言,歐美地區的國家,受到亞洲金融風暴的影響較小,所以整體的價量關係在亞洲金融風暴期間並無重大改變。本章的結果都是透過分量迴歸所獲得。 第三章 股市價量因果關係的分量迴歸分析 摘要 本文依據分量迴歸設計 Granger 因果關係的新檢驗方法,並依此方法來檢驗幾個股市價量之間的因果關係。本文分析的股市包括日本、英國與美國等世界前三大股市,以及合稱亞洲四小龍的台灣、香港、南韓與新加坡等新興工業國家或地區的股市。實證結果顯示:除了台灣股市以外,其他的股市皆呈現 “V” 字的跨期價量關係。其中英國、美國、香港和新加坡股市的跨期價量關係大體呈現正向「價量齊揚」與負向「價量背離」互相對稱的 “V” 字關係,而日本和南韓股市則是「價量齊揚」較強的不對稱 “V” 字關係。此一結果表示這些股市的價量之間都存在分配上的 Granger (1969) 因果關係。但若以均數迴歸來衡量跨期價量關係,則所有股市都呈現不顯著的跨期價量關係,也就是傳統文獻上所謂價量之間沒有 Granger 因果關係。本文所提出的 Granger 因果關係之分量迴歸分析,可以觀察到整個條件分配中各分量的因果關係,為分配上的 Granger 因果關係提供一個較完整的檢驗方法。 / We examine the relationship between the stock return and trading volume in the Taiwan and U.S. Stock Exchanges using quantile regression. The empirical results show that the return-volume relations in these two exchanges are quite different. For Taiwan data, there are significant positive return-volume relations across quantiles, showing that a large positive return is usually accompanied with a large trading volume and a large negative return with a small trading volume, yet the effect of former is stronger. However, such relations change when returns approach the price limits. We also find that for U.S. data, return-volume relations exhibit symmetric V-shapes across quantiles, showing that a large return (in either sign) is usually accompanied with a large trading volume. On the other hand, linear regressions estimated by the ordinary least square method are unable to reveal such patterns. Further investigation shows that various restrictions on short sales in the Taiwan Stock Exchange may explain the difference between the return-volume relations in Taiwan and U.S. data.
