我國公司治理評等指標建立之研究

林尚志 Unknown Date (has links)
建構一套健全的公司治理評等機制,為落實公司治理相關議題的核心工作。本研究以經濟暨合作發展組織之公司治理原則、世界銀行之公司治理架構與國內外公司治理相關實證文獻作為理論基礎,透過分析量化之公司層級衡量指標,嘗試建構一套可行且適合衡量台灣企業之公司治理評等指標,以作為投資人制定投資決策與授信機構評估企業債信風險時之參考。 本研究以2002年國內523家非金融業上市公司為樣本,利用LISREL方法 (線性結構關係模式統計方法)建構台灣公司治理評等指標。分析結果共得出:股權結構構面 (盈餘股份比、專業機構投資者持股率);董事會職責構面 (盈餘席次比、外部董事席次比率、外部監察人席次數與外部董監持股率);財務透明度構面 (盈餘管理幅度、損益平穩化程度與財報重編率)等3個構面、9項衡量指標。 透過與企業當期及次期經營績效、公司價值與投資人投資風險間之關聯性實證測試,本研究發現,前項公司治理評等指標與企業之經營績效、公司價值呈顯著正相關,而與投資人投資風險呈顯著負相關。此項實證結果一方面顯示,前項公司治理評等指標愈佳,企業當期與次期之經營績效與公司價值愈高,投資人之投資風險愈低;另方面亦表示本研究所建構之公司治理評等指標對於企業之經營績效、公司價值與投資人投資風險,具有一定程度之關聯性與預測能力。 / A well-developed corporate governance ranking system is essential to implantation of corporate governance. Base on principles proposed by OECD, a framework provided by the World-Bank and empirical literature on corporate governance, this research attempts to develop a workable TCGI (herein Taiwan Corporate Governance Index or TCGI) ranking system. The purpose of provision of TCGI is to help investors and creditors to make better decisions. Using data for 523 non-banking corporations publicly traded at Taiwan Stock Exchange in 2002, and LISREL as the analytical tool, this research constructs a three-aspect (including ownership structure, responsibility of the board and financial transparency) TCGI ranking system with 9 corresponding indicators in total. The empirical results of association tests show that TCGI indicators are significantly and positively (negatively) related to operation performance and market value (the occurrence of firms encountering financial difficulties). The findings thus imply that the TCGI ranking system developed in this research may be useful in investors and creditors decision-making.

上限型股權連結保本票券之評價、避險和風險控管 / Valuation, Hedge and Risk Management of Capped, Equity-linked and Principal-protected Notes

陳芬英, Chen, Fen-ying Unknown Date (has links)
本論文含蓋三篇文章,分別從評價、避險和風險控管三方面,分析上限型股權連結保本票券。 第一篇文章為上限型股權連結保本票券之設計、評價和比較。本文考量投資人保守的投資行為與設限型股權連結票券所存在的delta跳躍(delta jump)現象,延伸Brennan and Schwartz (1976)模型,提出一個能在股價波動之際,使發行的避險部位delta呈現平滑變動且兼具保本(protected principal)功用的一般化模型(general form)。相較於一般的設限型股權連結保本模型,本模型具有以下特色。第一,加入股價成長率的調整因子(adjustable factor),當景氣低靡,股價不停下跌時,正的調整因子可減緩股價下滑之勢,進而增加投資人在票券到期日時獲取更多資本利得(capital gain)的機會。同時,調整因子縮小了當期股價成長率與股價上限成長率(capped stock growth rate)之間的差距,繼而減緩delta 跳躍的幅度,降低發行者的避險成本。並且在HJM利率模型下,delta隨股價與股價波動度的變化更顯平滑(smooth)。第二,在保本率(protection rate)和參與率 (participation rate)不變之下,本模型的期初合理價格(fair price)較低,投資人能以較低的成本取得同等的投資保障。第三,若將本票券的名目面額(notional principal)視作共同基金(mutual fund)的淨值(net value),而該淨值與股價連動,則本模型即成為股權連結的保本型基金(principal-protected fund)。 第二篇文章是路徑依賴之上限型股權連結保本模型之評價和風險測量。該文是擴展Brennan and Schwartz (1976)模型發展一個路徑依賴之上限型股權連結保本模型,並且提出一個比二元數模型更精確的封閉解。此外,也對七個時間序列進行股價波動度之精確檢定,得知AR-ARCH(1)模型對上限型股權連結保本票券而言,較其它時間序列模型,更能有效估計股價之波動度。 第二篇文章是外國資產的風險管理。目前在國內金融市場上,國外金融商品很多,大都以外幣計價,因此匯率風險是投資人不可忽視的因子。本文拓展Kupiec(1999)模型,將匯率風險加入模型中,使投資人更有效進行風險管理。 / This thesis studies valuation, hedge and risk management of capped equity-linked and principal-protected notes by means of the following essays: (1) Design, Valuation and Comparison of Capped Equity-linked and Principal-protected Notes (2) Valuation and Risk Measurement of Capped Equity-linked and Principal-protected Notes with Path Dependence (3) Risk Management of Foreign Assets Capped equity-linked and principal-protected notes are similar with barrier options. There exists delta jump as stock price or growth rate reaches the barrier. But previous studies about equity-linked and principal-protected notes with a restricted growth rate of stock price never explicitly discussed how the delta jump could be solved. In my first essay, I present a new design for capped equity-linked and principal-protected notes and add an adjustable factor to growth rate of stock price in such a way that the adjustable factor narrows the gap between the current stock growth rate and the capped stock growth rate and thus really reduces the magnitude of the delta jump and hence lowers the hedging cost for brokers. Recently, the focus of previous studies about principal-protected notes has been on either the restriction on the rate of stock return or the path dependence on the underlying asset, but not both in the same context. In my second essay, I develop a model on the capped, equity-linked and principal-protected notes with path dependence. There are two issues in this article. The first issue is valuation on the capped, equity-linked and principal-protected notes with path dependence. I find a closed-form approximation using the 2nd-order Taylor approximation and the method of Vorst (1992) that has higher accuracy than binomial tree model as maturity time or volatility becomes large. The second issue is risk measurement. I use VaR model to evaluate market risk of the principal-protected notes, and employ seven univariate time series models to forecast volatility and examine the accuracy. Additionally, investors may well encounter potential loss as the prices of financial products are reduced in the secondary market. The VaR is mainly concerned with the downside risk and becomes a standard measure of financial market risk that is increasingly used by investors. But if we want to apply 〝textbook〞formulation to risk management of foreign assets, there leaves exchange rate risk out of consideration. Therefore, I extend the work by Kupiec (1999) to present VaR formula with exchange rate risk for foreign assets and then to manage market risk usefully.

合法賭場治理之法律問題研究─以新加坡及澳門法規範為中心 / A study of the Casino's Governance─Focusing on Singapore & Macau's regimes

吳家林, Wu, Ja Lin Unknown Date (has links)
對於我國是否應開放合法賭場?在台灣已爭論十年以上。2009年1月23日修正公布《離島建設條例》增訂第10條之2,正式開啟我國於離島設置合法賭場之可能。 從中國澳門及美國開放合法賭場帶來經濟效益的經驗,加以新加坡2005年4月18日宣布,將開放成立兩處賭場度假村(Integrated Resort)以掌握賭場帶來的巨大觀光收益與稅收,似提供贊成我國引進合法賭場經營的有利論證。然對我國政府或官員而言,甚至學術研究領域,仍屬於相當陌生的新興產業;尚缺乏全盤性理解,尤其是外國法制的規範架構及內容的了解。 本論文以新加坡及澳門賭場管理法制為研究中心,採比較法學的方法,分析此二政府對賭場管理法制架構之異同,以作為我國未來建構賭場管理法制架構及內容之參考。另歸納賭場管理法的法律性質,及引進經濟學分析闡述其與賭場管理法制設計之關聯,是本論文另一重點所在。透過經濟學比較靜態的分析,提供新的法制設計思維。 本論文不辦證「開放合法賭場之利弊得失?」,而直接進入「政策已決定我國將開放合法賭場經營」之假設。就賭場管理法之法律性質,本研究歸納五項:一、是引進新興產業及增加投資的法律;二、是特許經營的法律;三、是具嚴格監控的法律;四、是慎選國家代理人的法律;五、是重視社會成本最小化的法律。此於第二章有詳細說明,並定位本論文之總論。 本論文第三章以下為各論之法制研究。分別以賭場特許執照之核發與撤銷、賭場營運之治理、賭場內部控制制度、賭場專責機關之設立等4章,作為分析新加坡及澳門賭場管理法制之架構。 最後,提出本研究之結論與建議:一、開放賭場合法化,應同時考量經濟利益與社會成本的效益;二、應建立嚴格治理的監理法制;三、設計降低社會影響衝擊的機制;四、強化股權控制與關係人之規範;五、賭場內部控制內容應提升至法律位階;六、賦予賭場專責機關較大的監理權限。
