財務三大決策：投資、融資與股利政策一直是學術界研究探討的主題，也是實務界關心的重要課題。過去有關融資與股利支付宣告的文章不少，但投資支出相關研究則一直被視為股權結構下的控制變數，鮮少學者探討有關投資宣告對公司價值的影響。 本研究嘗試從資訊不對稱的角度，探討首度上市上櫃公司管理當局為傳遞公司經營績效及未來成長機會給予外部投資人，透過自身的持股與投資規模進行初次投資宣告，藉以傳遞公司真正價值予投資人，以追求公司與自身財富的最大化。本研究在訊號放射理論的架構下，透過完美貝氏的分離均衡解，經過模式推導獲致三個研究命題，並以此研究命題、個案訪談與文獻整理推衍出可驗證的八個假說。 在假說驗證方面，以民國80年至89年共225家新上市上櫃公司的初次投資宣告為研究樣本，並依未來前景看佳與否、股權集中度高低與初次宣告投資規模大小來分類，將研究樣本區分為八個子樣本，利用事件研究法對宣告公司事件日的平均異常報酬率反應以及累積異常報酬率反應進行假說的檢驗。並且，以產業類別、高階主管持股、高階主管持股的二次方、投資規模、初次投資支出類型為自變數，公司規模、市場景氣與負債比率為控制變數，對事件窗口(-1,+1)的累積平均異常報酬率進行橫斷面迴歸分析，探討宣告事件對股票異常報酬率反應的影響。經由上述的實證過程，本研究獲得以下主要結論： 1.初次投資宣告具有資訊內涵，當股權集中度越高的高科技股公司，若進行大規模的初次投資支出宣告，則公司股票異常報酬率的正面反應訊號越強。 2.投資人對高科技股與非高科技股公司的初次投資宣告有不同的評價，屬於未來前景看佳的高科技股，進行初次投資宣告的股票異常報酬率反應顯著為正，且顯著高於未來前景不佳的非高科技股公司。 3.屬於資本支出類型的初次投資宣告有利於公司價值的提升。 目錄 第壹章 緒論…………………………………………... 1 第一節 研究動機與研究目的……………………………… 3 第二節 研究範圍與研究限制……………………………… 8 第三節 研究流程與論文架構……………………………… 11 第貳章 文獻探討與個案訪談整理…… ……………. 17 第一節 代理理論與資訊不對稱…………………………… 18 第二節 股權結構與公司價值之關係……………………… 23 第三節 資本支出與公司價值之關係……………………… 28 第四節 股權、資本支出與公司價值相關實證文獻……… 31 第五節 文獻評述與個案訪談整理………………………… 50 第參章 理論模式建立…………………… …………. 59 第一節 模式背景……,,…………………………………… 60 第二節 模式架構與模式條件設定………………………… 63 第三節 模式推導與命題建立……………………………… 72 第肆章 研究設計… ………………………………… 81 第一節 實證架構與研究假說……………………………… 82 第二節 資料來源與樣本選取……………………………… 93 第三節 變數操作性定義…………………………………… 96 第四節 實證分析方法……………………………………… 102 第伍章 實證結果分析…… ………………………… 113 第一節 樣本資料統計分析………………………………… 114 第二節 全體樣本初次投資支出宣告的效果分析………… 121 第三節 研究假說的驗證……………………………………. 132 第四節 投資支出宣告異常報酬率影響因素分析………… 150 第五節 實證結果與涵義……………………………………. 154 第陸章 結論與建議…… …………………………… 163 第一節 結論………………………………………………… 164 第二節 建議………………………………………………… 166 參考文獻 中文部分……………………………………………………… 171 英文部分……………………………………………………… 173 表目錄 表2-1 國外其他股權結構與公司價值關係實證文獻整理… 36 表2-2 國外其他資本支出與公司價值關係實證文獻整理… 43 表2-3 個案訪談發現與對本研究的涵義……………………. 56 表3-1 研究模式的前提設計…………………………………. 67 表3-2 研究模式符號說明……………………………………. 68 表4-1 研究範疇的分類情形…………………………………. 86 表4-2 研究範疇的分類情形與對應的假說…………………. 90 表4-3 市場景氣劃分……………………………………… 101 表5-1 整體上市上櫃公司的分配狀況……………………… 115 表5-2 研究樣本按初次投資支出宣告年度分類…………… 116 表5-3 研究樣本按產業類別分類…………………………… 117 表5-4 研究樣本按高科技類股與市場景氣分類統計……… 118 表5-5 各研究變數的樣本統計量…………………………… 119 表5-6 全體樣本初次投資支出宣告的平均異常報酬率…… 122 表5-7 全體樣本事件窗口累積異常報酬率………………… 123 表5-8 高科技股公司初次投資支出宣告的平均異常報酬…. 125 表5-9 非高科技股公司初次投資支出宣告的平均異常報酬率126 表5-10 高科技股公司事件窗口累積異常報酬率…………… 127 表5-11 非高科技股公司事件窗口累積異常報酬率………… 127 表5-12 投資規模大的公司初次投資支出宣告的平均異常報酬129 表5-13 投資規模小的公司初次投資支出宣告的平均異常報酬130 表5-14 投資規模大的公司事件窗口累積異常報酬率……… 131 表5-15 投資規模小的公司事件窗口累積異常報酬率……… 131 表5-16 研究樣本交叉分類分布情形(n=225) ……………… 132 表5-17 第一種情況公司初次投資支出宣告的平均異常報酬率134 表5-18 第一種情況公司事件窗口累積異常報酬率 135 表5-19 第二種情況公司初次投資支出宣告的平均異常報酬率136 表5-20 第二種情況公司事件窗口累積異常報酬率……………137 表5-21 第三種情況公司初次投資支出宣告的平均異常報酬率138 表5-22 第三種情況公司事件窗口累積異常報酬率……………139 表5-23 第四種情況公司初次投資支出宣告的平均異常報酬率140 表5-24 第四種情況公司事件窗口累積異常報酬率……………141 表5-25 第五種情況公司初次投資支出宣告的平均異常報酬率142 表5-26 第五種情況公司事件窗口累積異常報酬率……………143 表5-27 第六種情況公司初次投資支出宣告的平均異常報酬率144 表5-28 第六種情況公司事件窗口累積異常報酬率……………145 表5-29 第七種情況公司初次投資支出宣告的平均異常報酬率146 表5-30 第七種情況公司事件窗口累積異常報酬率……………147 表5-31 第八種情況公司初次投資支出宣告的平均異常報酬率148 表5-32 第八種情況公司事件窗口累積異常報酬率……………149 表5-33 累積異常報酬率的橫斷面多元迴歸分析………………153 表5-34 各研究假說實證結果……………………………………158 圖目錄 圖1-1 研究流程………………………………………………. 12 圖3-1 初次投資支出宣告的信號放射………………………. 63 圖3-2 研究模式與觀念架構………………………………... 65 圖3-3 初次投資出宣告的樹狀機率分析…………………… 71 圖4-1 實證架構…………………………………………………82 圖4-2 實證分析方法與流程……………………………………102 圖4-3 事件研究的各時間參數的關係……………………… 105 / Previous foreign studies on corporate investment impact on market prices have revealed that investors react positively to the announcement of increases in capital expenditure. But, the few papers study the topic in Taiwan. This study applies the agency theory, the signaling theory which reduce the asymmetric information and agent problems between the management and external investors and the perfect Baysian Equilibrium to construct the theoretic model to analyze the effect of the initial investment announcement. Following the theoretical model, case interview and literature review, the study derives the three propositions and eight hypotheses. We test these hypotheses for the publicly traded corporations in Taiwan considering a sample composed of the initial investment announcement. The period of the study was January 1991 to December 2000, and the firms selected were all companies listed on the Taiwan Security Exchange or the OTC. The number of the initial investment announcements initially collected was 365 for publicly traded corporations. Nevertheless, the final sample was reduced to 225 after excluding the confounding events and other screen. Finally, we separated the full sample to eight sub-samples by corporate type, ownership and investment scale and used the event study and regression analysis to test the information effect of the initial investment announcement. Our empirical results are not hold in the full sample since no significant market reaction, but are supported in the sub-samples grouped by high-tech. Moreover, the initial investment announcements of high-tech, high ownership, and high scale companies lead the significant positively abcdrmal rate of return at the announcement day. In addition, the investors significantly positively react to the initial investment announcements belong to the capital investment.

本文考慮當資訊不對稱下的逆向選擇問題存在時,如何遵循Myerson(1979)提出的揭露原則 (the revelation principle)來設計一套具備誘因相容性 (incentive compatibility)的存款保險契約,契約中的自有資本比率為要保機構的自我選擇變數 (self-selection variable),而保險費則為存保公司用來控制要保機構決策行為的控制變數(control var iable),依此可以建立一套自我選擇機能(self-selection mechanism),來促使要保機構誠實揭其風險類型的私有訊息(private information),進而將要保機構依風險高低正確分類,徹底解決訊息不對稱下的逆向選擇問題。

租賃是使用權與所有權分離的一種企業或個人取得資產使權的方式。但是租賃市場中卻隱含二種潛在的訊息不對稱問題--逆向選擇與道德機問題。本文首先導出存在逆向選擇問題時之最適租約，並與充分訊息時之最適租約相比較。隨後我們也導出道德危機與逆向選擇問題並存時之最適租約。 　　有鑑於租賃對企業與個人的重要性，本文希望利用機制設計的方式來設計出存在訊息不對稱問題下的最適租約，以幫助租賃市場更有效地運作。針對逆向選擇問題，我們希望能利用誘因相容的直接控制機制，透過契約的設計，由承租人自己選擇租約，來幫助出租人分辦承租人之類型，並依此決定最適的租賃契約。針對道德危機問題，探究其成因主要是由於租約到期時資產的殘值完全不影響承租人報酬所致，所以我們希望能設計一組能使作維護努力的承租人得到充分獎勵的租約，也就是透過讓承租人作努力決策時將資產殘值納入考量的方式，使承租人的努力決策對出租人也是最適的。

本論文為關於營利與非營利機構之營運管理策略之兩篇理論性質的文章。 第一篇文章旨在探討營利機構之實質盈餘管理策略。本研究檢驗在產品市場競爭下，公司如何透過實質盈餘管理策略來滿足盈餘目標之要求以及公司之實質盈餘管理動機會如何影響市場競爭對手之行為。本文考慮一個兩期非合作之R&D競爭寡占模型。本文假設存在資訊不對稱；具有私人資訊的廠商為追求獲利最大亦或追求盈餘目標達成兩種類型。本文透過完美貝氏均衡 (perfect Bayesian equilibrium) 解出分離均衡 (separating equilibrium) 與混和均衡 (hybrid equilibrium)。 本研究指出追求獲利最大類型之廠商可以藉由影響競爭對手之猜測來進一步左右追求盈餘目標達成類型之目標達成之可能性。在分離均衡中，當外在成本衝擊未超過預期時，追求獲利最大類型之廠商無誘因藉由R&D 投資水準之提升來規避負向成本衝擊以影響市場對手猜測並且進一步提升其產品市場競爭力。因此，追求盈餘目標達成類型之盈餘目標無法達成。 在混和均衡中，當外在成本衝擊超過預期時，追求獲利最大類型之廠商有誘因採取混合策略以誤導市場對手之猜測;該類型之廠商可以藉由部分模仿盈餘目標達成類型之R&D 投資策略以混淆競爭對手之信念並且提升其產品產出、獲利水準。在此，追求盈餘目標達成類型之盈餘目標能夠達成。本研究之結果有別於傳統R&D盈餘管理實證文獻中，公司內部當局有誘因透過R&D支出的減少用以滿足公司短期之盈餘目標 (Barber et. al., 1991; Bushee, 1998; Graham, 2005) 。本研究指出公司可以藉由R&D 投資水準之提升，以創造“cookie jar” 並且有助於公司獲利提升與盈餘目標之達成。此外，本研究與盈餘奇異現象之實證研究 (earnings kinky) 結論一致: 公司可以藉由盈餘管理策略來達成盈餘目標，但是盈餘目標之達成不盡然是透過盈餘管理策略 (Dechow, Richardson and Tuna, 2003)。 第二篇文章旨在探討非營利機構提供非獲利性質服務之策略性之影響。本研究指出非獲利性質服務之提供不僅有助於非營利機構於獲利性質服務之競爭優勢的提升，相對於營利機構。當所有權與經營權分離時，若市場需求彈性為不具彈性時，非獲利性質服務之提供對非營利機構之經理人而言，可以做為一個策略工具藉以促使該機構之所有人提供一個於獲利部分過分補償之薪酬水準。此外，隨著非獲利性質服務之外生價格的提升，當非營利性質服務之外生價格的提升對於非營利機構之所有人與經理人利益衝突影響之間接效果大於對獲利性質服務價格影響之直接效果時，非營利機構之所有人仍然會提供一個獲利部分過分補償之薪酬水準。這會有助於非營利機構於獲利性質服務之競爭優勢的提升。 / This dissertation consists of two theoretical studies on the operation strategies of for-profit and non-profit firms. Chapter 1 addresses how firms use real earnings management to meet or beat their earnings targets, and how this influences sequential product market competition. We study this issue in a two-period non-cooperative R&D competition with one-sided asymmetric information in which the informed firm could be either the maximizing type or the target-meeting type (or target-beating). We show that the maximizing type of the informed firm’s R&D investment level could influence rival firm’s conjecture about the informed firm’s type which in term affects the success of meeting or beating the target for the target-meeting type of the informed firm. We find that the privately informed firm can increase its R&D investment in the first period to meet or beat the earnings target. This can help the firm increase profits in a sequential product market competition. More precisely, once the cost uncertainty realized is realized to exceed expectations, the maximizing type of the informed firm could hide its identity by adopting a mixed strategy and setting its R&D investment and output level higher than in the separating equilibrium. Contrary to popular claims that meeting or beating short earnings targets induces an R&D investment reduction (Barber et. al., 1991; Bushee, 1998; Graham, 2005), we show that R&D overinvestment can give an opportunity to create some reserves, i.e., a cookie jar, to be used later to earn a higher profit and reach later targets. Our result is also supporting the observation of firms meeting or beating the earnings target, but not necessarily using earnings management (Dechow, Richardson and Tuna, 2003). Chapter 2 shows that the provision of not-for profit service would not only give not-for-profit organizations a competitive advantage over for-profit organizations. Under the separation of control and ownership, we illustrate that once market demand is inelastic, the provision of not-for-profit service serves as a strategic device for the manager of a not-for-profit organization and thus induces the owner of a not-for-profit organization to overcompensate his manager regarding the margin of profit. Moreover, as the regulated price of not-for-profit service increases, a not-for-profit organization could still over-compensate his manager in regard to profit, when the indirect effect on increasing preference difference between the owner and manager of the not-for-profit organization dominates the direct effect on market price. Thus, a not-for-profit organization could charge more in for-profit service.

本研究提出UIP、PPP、 MF、TR及TRa五種匯率預測模型，以新台幣兌美元即期匯率、遠期匯率進行避險準確率及避險成效的實證分析。資料期間為1996年12月到2012年10月的新台幣兌美元即期匯率月資料，資料來源為資料庫Datastream。 實證結果發現UIP、PPP、 MF、TR及TRa五種匯率預測模型比較分析中，若以相對購買力平價模型(PPP)進行選擇性避險，再搭配適當避險比率，其報酬率可能由負報酬轉為正報酬；避險績效衡量方面，以相對購買力平價模型搭配完全避險的績效最好。若以不對稱泰勒模型(TRa)進行選擇性避險，再搭配適當避險比率，報酬率明顯由負轉為正；衡量避險績效衡量方面，完全避險在風險降幅及下方動差避險績效衡量下，以不對稱泰勒模型搭配完全避險的績效最好。 / This study provides five exchange rate models to predict future exchange rate (UIP,PPP,MF,Taylor rule and asymmetric Taylor rule). We illustrate these methods by assessing the forecasting performance of five exchange rate models using monthly returns on TWD/US dollar exchange rate. The data are monthly exchange rates ranging from December 1996 to October 2012, using spot and one-month forward exchange rates form Datastream. We find that empirical models based on purchase power parity (PPP) and the asymmetric Taylor rule(TRa) outperform the other models in out-of-sample forecasting using the appropriate hedging ratio. Comparing the hedging performance between PPP and models, we find that the hedging performance by the PPP will get the higher return. However, the hedging performance by the will get the lower volatility.

本研究主要探討股權重組活動對公司治理的影響，以及股權重組與公司治理程度是否會影響經營績效。多角化原為企業增強經濟效率、發揮綜效的策略，但近年來發現，企業多角化有折價的現象。又諸多折價現象中，發現企業產生了內部價值衝突的狀況。推敲折價現象的發生，可能與管理者能力有關，當組織越廣大而多層下，管理能力不堪負荷企業的經營效率將因為業務種類越廣而降低。 從臺灣的個案訪談中，了解到小股東對分割宣告的態度多為保守而疑慮的，未若歐美文獻所探討的對股東財富具有正面的激勵。因此，本研究探討股權重組所欲達成的目的是否對公司治理有正面的幫助，並進一步以子公司的上市為基準點，討論上市前管理能力、公司治理與股權重組目的之前是否具備關聯性，並研究上市後股權重組目的、公司治理與經營績效之前是否具備關聯性。 主要貢獻如下: 1. 股權重組是企業從多角化走向分權、業務單純化的程序，股權重組有 利於讓外部投資人減少資訊不對稱的困境，在分別評價不同性質企業下，有助於回復多角化折價所失去的價值。 2. 管理能力隨著企業的發展，會提高或降低。管理者表現不佳未必要以撤換管理者為唯一手段，且要提高管理者努力程度也不盡然是以設計良好的獎酬制度，原因可能是內部資源配置不佳，而股權重組是協助企業改善內部資本市場缺乏效率性的重要手段。 3. 股權重組是讓單一實體企業創建兩個獨立的企業個體，他會引進新得股東、外部專家與讓管理者更可直接接受外部市場評價，股權重組是否可讓企業更進一步地改善公司治理結構或減少盈餘管理現象，仍有賴企業分割的真實目的。在臺灣，資產分割對股東財富的影響為負效果，有別於歐美資本市場；權益分割雖為正的財富效果，但反應也不如歐美市場的表現。 4. 管理能力與公司治理表現會影響股權重組的推動，股權重組的目的與公司治理的表現會影響經營績效。 / 1.Ownership Restructuring Relationships Equity Carveouts and Spin-offs were called “Ownership Restructuring Relationships”. Equity Carveouts are usually followed by spin-offs. Spin-offs are more often associated with controlled subsidiaries. In a spin-off, a company distributes on a pro rata basis all the shares it owns in a subsidiary to its own shareholders. Two separate public corporations with the same proportional equity ownership now exist where only one existed before. Equity Carveouts means “ A company sells up to 20% of the stock of a segment to raise funds followed by a tax-free spin-off. Spin-offs are distinguished from equity carveouts, in which some of a subsidiariy’s shares are offered for sale to the general public, bringing an infusion of cash to the parent firm without loss of control. In any cases, management may seek to split the company into small pieces through a series of restructuring techniques. Including initial equity carveouts and subsequent spin-offs. 2.Wants Taiwan listed Companies have incurred on conflict between subsidiaries in recent years. They usually take the step of Restructuring ownership relationship to approach their strategy, we exploring the cause and consequence among financial strategy, corporate governance and performance. The purpose of this paper is to explore the decision whether can impact on ability of manager or not. First, to develop a new path is main contribution in Corporate Governance. Second, to enhance the diversified field referred as Governance. Third, Which can increasing wealth of owner at the issue of spin-offs and carveouts in Taiwan. Fourth, After enacted the decision, What effect are their needs and the relationship between strategy and performance? 3.Literature Review (1)Restructure Several studies have examined the market reaction to the announcement of carve-outs (Schipper and Smith, 1986) and spin-offs (Hite and Owers,1983;Miles and Rosenfeld,1983; and Schipper and Smith,1983) These studies demonstrate that the announcement of a corporate spin-off or carve-out is associated with positive stock price movements in the parents’ stock. The continuity of ownership in a spin-off implies that any subsequent changes in value from the reorganization accure to the existing shareholders of the parent corporation. Galai and Masulis claim spin-offs may erode the position of the bondholders causing a wealth transfer from bondholders to stock holders while leaving the value of the firm unchanged. Schipper and Smith also contend that the creation of publicly-traded firms results in new information sources which enable shareholders to more closely monitor the activities of managers, thereby reducing agency costs and enhancing shareholder wealth. The asset focus explanation has viewed spin-offs as improving the focus of a firm, thus serving to remedy the loss of focus inherent in a diversified conglomerate. (2)Restructure and owners wealth A significant positive stock price reaction was surrounding spin-off announcements. The source of the gains in spin-offs, however, is difficult to identify and validate. Authors have argued that spin-offs:  Mitigate an unwieldy organizational structure by increasing focus.  Enhance contracting efficiency  Reduce regulatory or tax constraints  Reduce information asymmetries regarding the operatons of parent firms  Are possible corrections of acquisition mistake.  Improve managers’ incentives to maximize shareholder wealth in spun-off firms. Allen et al(1995)also document an inverse relation between the gains to spin-offs and losses associated with prior takeovers of those units by the parent firm. Krishnaswami and Subramaniam(1999) find that information symmetries in parent firms are positively related to the excess stock returns around spin-off announcements. While Daley, Methrotra, and Sivakumar(1997)report that focus-increasing spin-offs earn higher announcement-period excess stock returns relative to spin-offs that do not increase focus. Cusatis, Miles, and Woolridge(1993)find that the market for corporate control has historically played a major role in the wealth gains to shareholders of firms involved in spin-offs. The sources of the increasing in shareholder wealth which accompanying the announcement of a corporate spin-off. However, are not apparent. Hite and Owers(1983) and Schipper ;and Smith(1983) document that shareholder gains are related to neither wealth transfer from other financial claimants nor to the beneficial resolution of inefficient legal to regulatory contractual relationships. (3) Information Asymmetry and Restructuring Practitioners and the popular press usually propose an information-related motivation for spin-offs. CEO of most firms involved in spin-offs claim that the spin-off improves the firm’s market value because investors are able to perceive value more clearly after the spin-off. As information asymmetry hypothesis that a spin-offs increasing value. because it mitigates the information asymmetry in the market about the profitability and operating efficiency of the different divisions of the firm. Several studies have empirically analyzed the source of shareholder gains around spin-offs. We may be classified as follow: (i) transfer of wealth from bondholders to shareholders. (ii) tax and regulatory advantages, (iii)restructuring of incentive contracts synergies hypothesis has received broad empirical support. As spin-offs transform a shingle firm into many firms that have separate stock market listings, they increase the number of traded securities and make the price system more imformative. (4) Internal Capital Market The relative efficiency of internal and external capital market transactions is a critical element in defining the boundaries of the firm. Mackie-Mason(1990) says that internal capital markets are an empirically important mechanism by which capital is allocated across and within lines of business. Alchian(1969) and Williamson(1970) argue that internal capital markets are more efficient than external markets because corporate headquarters is likely to be better informed than external suppliers of capital about investment opportunities. Meyer, Milgrom and Roberts (1992), Wulf(1997), Rajan et al(2000) and Scharfstein and Stein(2000) argue that rent seeking by division al managers can distort the functioning of internal capital markets, inducing corporate headquarters to allocate excessive capital to divisions with poor investment opportunities where rent-seeking incentives are strongest. Shin and Stulz(1998) evidence that when capital is reallocated across divisions, it does not seem to go in any systematic way to the divisions with the better investment opportunities. (5) Governance and Restructuring While a well-functioning system of corporate governance and control should contribute to the development of competitive advantage, internal control practices may not always operate effectively. The restructuring of the U.S. economy that followed this century’s fourth merger wave can be seen as inefficiencies associated with firms’ pursuit of financial self-sufficiently and conglomerate diversification. Having said this, the work on internal control is limited in two ways. First, there have been few studies that consider director attributes, as well as the identity and compensation of CEOs simultaneously. Most work considers each as a topic worthy of its own investigation. Of course, these CEO and director attributes all comprise interrelated aspects of internal corporate control. And second, While Walsh and Seward (1990) acknowledged that a voluntary corporate restructuring could be seen as an attribute of internal control. Relatively little empirical work has been done on the topic within a governance and control framework. Our goal is to examine the relationship between a voluntary corporate restructuring and the more traditional internal corporate control mechanisms identifies by Walsh and Seward (1990). 4. Research Design (1)Hypothesis H1: The Goal of Restructuring Ownership Relationship is positive related with enhancing Degree of Corporate Governance; also is positive related with reduce Earning Management. H1-1: A predictable variable is reducing diversification which has positive related with the share-hold-ratio increasing in institutional investor. H1-2: The more forecast error from analysts, the less do add-up share hold-ratio from institutional investor; also the more is earning management from managers. H1-3: Earning quality increasing is positive related with institutional investor add-up their holds; also is positive related with manager decreasing their earning management. H1-4: Capital Expenditure decreasing is positive related with institutional investor add-up their holds; also is positive related with manager decreasing their earning management. H2: Restructuring Ownership Relationship can enforce the structure of subsidiaries’ governance, also loft the ability of top management. H2-1: If Insider Trading Index is lower at the subsidiaries after restructuring, the relationship with reducing agency cost is positive. H2-2: Board is positive related with reducing the agency cost. H2-3: The more influence power index is, the less agency costs are at subsidiaries’ restructuring. H3: Announcement is positive related with wealth effect. H3-1: announcement has positive abnormal return during event window. H3-2: Spin-off has negative accumulate abnormal return during announcement. Carveout have positive accumulate abnormal return during announcement. H3-3: the long-term in wealth effect which after restructure is superior to before restructure. H4: Among governance, restructuring and performance have positive relationship. H5: the performance means after restructure is superior to before restructure. (2)Event study The original sample consisted of 101 firms parent companies had spun-off subsidiary common stock to their shareholders over the period 1990 to 2005, and either sample consisted of 79 firms parent companies had carved-out subsidiary common stock to outsiders. The mean adjusted return approached was used to compute abnormal returns. Recent evidence by Masulis(1994) as well as the more sophisticated market models in detecting abnormal performance when it is present. To determine the adjusted daily returns of a security, the average daily return over specified interval, the comparison period return(CPR), it taken as an estimate of the expected daily return for the period under study, the observaton period adjusted returns are then computed by subtracting the CPR from the daily return over the observation period. The CPR for the current study is based upon the average daily return from day –210 through day –21, the observation period extends from day –10 through day +10 using the following formula: a. Average standard abnormal return:ASR= 。 b. Accumulated standard abnormal return: CASR= 。 (3) Logistical regress model We will test the relationship between goal of restructuring and governance to use the method in logistical model. Because the binary variables can catch add or deduct from institutional investor. Institutional investor may be proxy variable of enforce structure of Corporate governance that is depended variable by us. In addition to proxy of governance, We select another depend variable which is transparency on finance to be a proxy variable of earning management in stead of agency cost. If hold-stock-ratio is adding means the structure is better in the wholly year. And if transparency-on-finance is deducting means the cost is saver in the wholly year. Through binary variable to test the relationship is worse than multi-regression model, we only want to know the meaning whether restructuring of owner relationship is function of corporate governance to find the effect on financial decision. Suppose that the strong relationship is existed between restructuring and governance, hence, we will explore relationships among governance, restructuring and performance in advance. (4) Simultaneous Equation model If ability can impact on financial decision and producing effect indirectly on governance, how do governance and performance can impact on financial decision? There are many papers to discuss the efficient of internal capital market where were related with governance and performance from inference. The evidence-paper is scarcity and also non-suitable on Taiwan. We Seemingly see the consequence is well between variables, their relationship may be interact to display on cause and consequence. 5. Conclusion (1) We get a strong evidence to support the goal can influence on governance. Institutional investors need the sign to adjust their stock and join the better governance. (2) To approve the refocusing hypothesis those improve the performance and manager’s ability. Their purpose of taking the corporate restructure is not only owner wealth but also to modulate the internal resource on conglomerate. (3) Spin-offs is difference from carve out on wealth effect from announcement period. But they also have the common effect is positive on announce day. Spin-offs have negative abnormal return prior to announcement and carve out have positive abnormal return through announce day. Our conclusion is different from west papers. (4) Ownership structure have influence on performance, Suppose that highly controlled parent company get more inflow than lower controlled parent company, in the meaning of controlling shareholder or block holders will influence on performance and ability of manager through corporate restructure.

在保險市場中，保險商品主要透過保險經紀人、保險代理人以及保險人所掌握的直接通路予以販售，特別是在大型商業財產及責任保險的行銷通路上，保險經紀人扮演了舉足輕重的角色。本論文主要是以商業財產及責任保險市場為研究重心，並由經濟觀點探討保險經紀人的仲介角色、市場競爭態勢、報酬結構以及業務安排方式等，同時以保險監理的角度檢討保險經紀行業存在的誠信自律、利益衝突以及客戶公平對待等問題。 不同於保險代理人，保險經紀人係基於保單持有人之利益為其安排保險。因此，保險經紀人必須透過多家保險人提供報價的方式，從中選擇價格及條件最佳者做為保險業務安排之對象；換言之，誠實的報價程序，方足以保障客戶之利益並維繫保險市場的健全。然而國外近年發生的大型保險經紀人與部分保險人共謀提供不實之報價事件，不僅嚴重影響到保單持有人的權益，更引發了對於保險經紀人不當市場力量運用以及或有佣金（contingent commissions）制度存廢的廣泛討論。2004年10月14日紐約州總檢察官Eliot Spitzer向紐約州最高法院針對全球最大保險經紀商Marsh & McLennan及部分保險人所涉及的投標詐欺、操縱價格、收受保險公司或有佣金等三大罪狀提出了民事訴訟。此案例不僅使得涉案公司付出鉅額賠償，更暴露出大型保險經紀人公司存在已久的市場壟斷、價格操控、利益衝突等問題。 對照於英、美等國在保險經紀人制度方面的成熟與發達，我國在此方面尚屬新興發展階段，所謂他山之石可以攻錯，借重先行者的經驗，不僅可以避免重蹈覆轍，更可加快成長的腳步；在全球化的浪潮衝擊之下，保險經紀市場唯有與國際充分接軌，並健全相關制度，才能為國內保險市場的業務成長，帶來蓬勃生機，並立下永續發展的堅固磐石。 / In the insurance market, policies are sold through direct channels controlled by insurance companies or intermediaries, such as brokers and agents. Brokers play a vital role in the property & casualty insurance market and serving commercial clients with complex and large exposures. This report focusing on the commercial property & casualty insurance market, we look at the economic performance by brokers, the competitive structure of the marketplace, the compensation arrangements for brokers, and the placement with insurers. Furthermore, we also from regulators’ point of view to study and review a variety of issues, such as the ethics and conduct , conflict of interest, treating customers fairly, which are raised from insurance brokers industry. In contrast to captive agents, brokers act on behalf of the insured, for this circumstance, the role of the brokers is to increase price and coverage competitiveness, by providing the customers access to a wider range of possible insurers. Clearly the integrity of the bidding process is very important to protect the interest of customers and to the health of the insurance brokers market. Unfortunately, the integrity of the placement process by brokers has been questioned due to the allegations of bid rigging in which one or more global brokers and a few insurers appear to have conspired to submit non-competitive bids. This anti-competitive practice is not only detrimental to the customers but also cause public concerned that too much market power lead to abuses by brokers and that contingent commissions should be abolished. On October 14, 2004, New York Attorney General Eliot Spitzer filed suit against Marsh & McLennan alleging that the insurance brokers engaged in bid rigging and received widespread kickbacks from insurance companies. On January 31, 2005, Marsh agreed to pay $850 million in restitution to buyers as part of an agreement to settle the suit, but lawsuits still in progress. The above-mentioned case has revealed conflict of interest, anti-competitive and market manipulation for meg-brokers, in fact, these problems existed for a long time. Comparing with US and UK insurance brokers market, Taiwan is belong to emerging market, to gain knowledge of pioneer’s developing experience, we could shorten the time to get more progress. When we deal with the globalization challenge, local insurance broker market should be complied with international practices, improve relative rules and regulations is also necessary, once above situations are available, it could help domestic insurance market rapid and healthy growth.

第一篇文章係利用Meltzer and Richard (1981)所建構之中位數投票者模型，衡量政府進行所得重分配產生公共基金邊際成本大小。有別於過去研究公共基金邊際成本的文獻，假設租稅制度之現況為任意的或是在最適的均衡下，文章的主要貢獻在利用現存租稅制度本身代表著一個政治均衡的前題，推導出公共基金邊際成本之公式，故可以視為是將實證經濟學的特性應用在規範經濟學的領域之研究。有趣的是公式中以標準化後平均所得與中位數所得差距所衡量的所得不均度，可以用來衡量租稅的效率損失及重分配水準是否足夠。 第二篇文章係利用 Laffont and Tirole(1986)的最適廠商管制機制模型，加入Raith(2003)誘因給付契約模型，建構較符合實際社會狀況的雙層不完全資訊模型。文章的貢獻在發現廠商最適管制機制，除Laffont and Tirole（1986）指出受廠商工作努力誘因及資訊淨租之影響外，還受到員工風險厭惡程度、生產成本風險及工作努力邊際負效用增加速度等因素的影響。當生產成本風險愈高，或是員工風險厭惡程度愈大及工作努力邊際效用增加速度愈快，使得廠商與員工間道德冒險的成本愈大時，廠商最適管制機制愈偏向成本加成契約，而非Laffont and Tirole(1986)指出偏向固定價格契約。此結論可廣泛應用於包括國防採購、政府部門與公有、公用事業之管控等問題，例如，航太、軍火、高速鐵路等生產成本風險較高產業，廠商最適管制機制愈偏向成本加成契約；但電力、自來水等生產成本風險較低產業，廠商最適管制機制愈偏向固定價格契約。 第三篇文章討論過去文獻未分析的廠商最適利潤稅問題。廠商的實際利潤除有生產技術的差異外，還受員工工作努力及隨機變數等因素的影響。一方面，政府僅能觀察廠商事後利潤，並無法觀察其生產技術差異；另一方面，廠商也無法觀察員工工作努力及隨機變數等，兩者均存在不完全資訊的問題，因此，建構政府與廠商之間，以及廠商與員工之間的雙層不完全資訊架構，分析不同生產技術廠商的最適利潤稅對逆選擇、道德冒險及風險分攤的影響，是一個有趣且重要的課題。 本篇發現廠商最適利潤稅有兩種情況，當政府觀察廠商事後利潤不會產生替代效果下，應課徵定額稅(lump-sum taxes)；除此之外，若存在逆選擇的問題，透過模擬數值分析結果發現，廠商最適利潤稅邊際稅率與員工風險厭惡程度及生產風險成正比。此外，隨著廠商生產技術愈高，利潤稅邊際稅率則逐漸下降，而且廠商生產技術愈高，不同風險厭惡程度及風險下的利潤稅邊際稅率差異也逐漸減少。 當生產技術分配為柏拉圖(Pareto)分配時，最適廠商利潤稅邊際稅率較均等(Uniform)分配及對數常態(Lognormal)分配為低。當工作努力邊際效用與工作努力間為凸函數時，最適廠商利潤稅邊際稅率較兩者間為線性函數時為低。

本研究顯著地發展時間轉換Lévy過程在最適投資組合的運用性。在連續Lévy過程模型設定下，槓桿效果直接地產生跨期波動度不對稱避險需求，而波動度回饋效果則透過槓桿效果間接地發生影響。另外，關於無窮跳躍Lévy過程模型設定部分，槓桿效果仍扮演重要的影響角色，而波動度回饋效果僅在短期投資決策中發生作用。最後，在本研究所提出之一般化隨機波動度不對稱資產報酬動態模型下，得出在無窮跳躍的資產動態模型設定下，擴散項仍為重要的決定項。 / This study significantly extends the applicability of time-changed Lévy processes to the portfolio optimization. The leverage effect directly induces the intertemporal asymmetric volatility hedging demand, while the volatility feedback effect exerts a minor influence via the leverage effect under the pure-continuous time-changed Lévy process. Furthermore, the leverage effect still plays a major role while the volatility feedback effect just works over the short-term investment horizon under the infinite-jump Lévy process. Based on the proposed general stochastic asymmetric volatility asset return model, we conclude that the diffusion term is an essential determinant of financial modeling for index dynamics given infinite-activity jump structure.

俄羅斯聯邦是一個多民族國家，共有一百多個不同的民族生活在俄羅斯這塊土地上。這些少數民族有著自己的語言與文化，一有機會即想脫離俄羅斯獨立。尤其是車臣與韃靼斯坦這類文化差異較大的民族，一心渴望擁有自己主權。除了少數民族的獨立要求外，俄羅斯聯邦仍必須應付境內的地方主義聲浪。主要是因為俄羅斯的聯邦體制是由民族聯邦與區域聯邦結合而成的，境內有以民族為基礎的聯邦主體，同時也有以行政區域為劃分基礎的主體。 蘇聯晚期，俄羅斯總統葉爾欽為了與戈巴契夫爭權，喊出「你能夠拿多少主權就拿多少」的口號，各加盟共和國紛紛通過國家主權宣言，俄羅斯聯邦境內亦興起分離獨立氣氛。為了解決問題，葉爾欽於1992年3月與各聯邦主體分別簽署了3個聯邦條約，開始對中央與地方的權利義務關係作了說明。隨著政治情勢的變化，俄羅斯聯邦於1993年12月12日通過新憲法，明確的規範了中央與地方各自的權力，自此權力的行使有了依循的標準；1994年發生車臣戰爭，突顯出憲法無法解決所有問題，於是依據各主體需要簽訂的雙邊條約出現了，首先是俄韃條約，謂之「韃靼模式」。至此俄羅斯的聯邦體制大致完成。 俄羅斯聯邦體制的運作仍然存在許多問題，不論是在政治方面、經濟方面，甚或法律制度方面尚有不夠完善的地方。再加上地方主體的種類繁多，經濟條件、政治情況及文化取向差異甚大，影響著主體對聯邦關係的看法。因此要解決聯邦問題，就必須從制度上的缺陷及地方主體的態度來著手進行。 / Russian federation is a multi-national state, there are more than one hundred kinds of races. These minority races have their own culture and language, they desire to be independent from Russian federation, especially Chechenya and Tarstan. Besides independent demand, there still have localism in Russian federation. In Russian federation, there are two kinds of federal subject. One is ethno subject which based on races different from Russian, the other is territorial subject. Late years in Soviet Union, Russian president Yeltsin in order to struggle with Gorbachev, he said：“swallow what you can get”. Meanwhile, the Union Republics declare their sovereignty. The atmosphere in Russian federation is chaotic. To solve the problem, Yeltsin sighed three federal treaty with all subjects and define the right between center and subjects. Then 1993 passed the Russian Constitution, 1994 Chechen war exploded, that means constitution not suitable for every subject. Yeltsin decided to sign bilateral treaty with subjects, first one is Tartarstan Republic, called “Tartarstan Model”. Russian federal system still has several problems in politic, economic, and law, institution. Besides 89 subjects are so distinguished, their political condition, economic situation, culture are so different, all this affect their perception about federal relation.
