本研究目的在於探討Put-Call Parity（PCP）所隱含的買權、賣權與標的資產間的價格變動關係。藉由探討PCP偏差程度的動態行為，推論若PCP的偏差為隨機漫步過程，則無法達到長期穩定，隱含PCP的廣義關係無法成立；反之，若PCP的偏差具有回歸平均特性，表示長期會達到穩定狀態，則PCP的廣義關係成立。 在研究方法上本文以變異數比率法檢定指數選擇權的PCP偏差是否為隨機漫步過程，採用隱含利率和實際無風險利率的差代表PCP的偏差程度，利用馬可夫轉換模型描繪PCP偏差的動態行為，並使用Gibbs Sampling演算法說明參數的不確定性。 本文以S&P500和DAX為研究標的，並探討股利不確定性是否影響PCP廣義關係，得到下列結論： 1、 對於S&P 500指數選擇權而言，不論是以日資料或週資料估計VR，S&P 500的PCP偏差都無法提供回歸平均的證據，隱含S&P 500的PCP廣義關係無法成立。 2、 對於DAX指數選擇權而言，檢定日資料的結果發現，DAX之PCP偏差在長期時（40~50日）有明顯的回歸平均的證據；而在檢定週資料時，使用原始資料法在90%信心水準下，不論取任何lag都可拒絕虛無假設，使用標準化資料則無法提供明顯的回歸平均證據。 3、 比較S&P 500和DAX，檢定日資料與週資料的結果都發現，DAX的p-value都比S&P 500小，並且S&P 500的PCP偏差都無法提供回歸平均的證據，而DAX有明顯回歸平均現象，隱含在消除股利的不確定性後，指數選擇權PCP的廣義關係式成立之證據較強烈。

La mondialisation de l’économie, le développement des moyens de transport et de communication et l’émergence des paradis fiscaux rendent la connaissance de la fiscalité d’autres pays indispensable, tant par le fiscaliste praticien que par le chercheur.La France et la Belgique ont une communauté de langue et de culture en plus de la proximité géographique. Connaître sa fiscalité et la comparer à la fiscalité française est utile à tout fiscaliste qui pourra alors se faire sa propre idée sur le statut de paradis fiscal qu’on lui attribue. Nous avons choisi de comparer l’imposition des revenus étrangers car, ceux qui changent de pays pour éviter la pression fiscale, sont souvent des personnes ayant une forte activité internationale. En l’absence de convention préventive de double imposition, l’imposition de tels revenus est plus favorable en France, quand ils sont encaissés par des personnes morales. En revanche, lorsqu’ils sont encaissés par des personnes physiques, l’imposition est plus avantageuse en Belgique.Mais les deux pays ont conclu beaucoup de conventions préventives de double imposition de sorte qu’il est difficile de trouver un pays qui ne leur est pas lié par une convention fiscale. Or, il s’avère que la Belgique, à travers ses conventions, adopte des mesures fiscales nettement plus favorables que la France et ce, afin de favoriser l’expansion économique de ses résidents et attirer aussi des capitaux étrangers.A cette situation, s’ajoute le fait que ce pays autorise des montages fiscaux qui seraient sanctionnés en France sous l’angle de l’abus de droit.On comprend alors pourquoi certains hommes d’affaires n’hésitent pas à s’y domicilier. / According to several factors such as the economy globalization, the development of transportation and communication supplies and the rising of tax heavens, tax lawyers have to reach a high expertise and knowledge of foreign tax systems.Belgium and France share common roots of language and culture in addition to the geographical proximity. To be especially aware of the Belgium tax law scheme is absolutely necessary for every tax lawyer in particular in a view to compare and have an opinion about the heaven nature of the Belgian system.As far as it is impossible to compare every point of the two systems, we decided to focus only on the taxation of foreign income, because of the international activity of the taxpayers willing to lower the tax pressure. Without an international tax treaty, foreign incomes are less taxed in France when they are received by a company but the situation is different when the receiver is a person. However it has to be noticed that Belgium and France have developed a huge international tax treaty network. The Belgium one is analyzed as being more attractive for foreign investments and national economic expansion. Besides, Belgium has a tax system which authorizes tax schemes seen sometimes as an abuse of right in France. As a consequence the exile of business men can be understood.

It is justified by the economic importance that this sector is assuming in Brazil with respect to investments in infrastructure that have already been and are going to be made. The highway concession segment in Brazil has expanded since the second half of the 1990s. Until this date there are more than 50 highway concession companies throughout the country, responsible for investment commitments of more of them R$ 10 billion related to improving and expanding the brazilian highway network. The highway concessions are specific purpose entities with a defined service life and holders of a concession right that permits them to commercially exploit segments of highways through charging tolls from the users, in exchange for assuming commitments to provide determined services and to implement investments for improvement and expansion during the concession agreement. In some cases the concession also assumes the commitment of payment of a right of concession to a Granting Authority. In this dissertation the application of valuation methods for companies, based on discounted cash flows, dividend flows, internal rate of return, payback and value multiples such as the ratio between enterprise value and its EBITDA are considered. These methods were used in the valuation of the five highway concessions granted by the Government of the State of São Paulo in the public auction that took place in October 2008. The results of this valuation as well as a critical analysis of the adequacy of the above-mentioned valuation methods are presented in chapter V and the conclusions are presented in chapter VI of this dissertation / Este trabalho tem por objetivo estudar os problemas relativos a aplicação de métodos de avaliação de empresas em concessões de rodovias no Brasil, e justifica-se pela importância econômica que esse setor vem assumindo no país no que tange aos investimentos de infraestrutura realizados e a realizar. O setor de concessões de rodovias no Brasil tem se expandido desde a segunda metade da década de 90. Existe até esta data mais de 50 empresas de concessões de rodovias em todo o país, responsáveis por compromissos de investimentos de mais de R$ 10 bilhões relativos a melhoria e expansão da malha viária brasileira. As concessões de rodovias são Sociedades de Propósito Específico com vida útil definida. Detentoras de um direito de concessão que lhes permite explorar comercialmente trechos de rodovias por meio da cobrança de tarifas de pedágio dos usuários, em contrapartida, assumem o compromisso de prestar determinados serviços e implantar investimentos de melhoria e de expansão ao longo do contrato. Em alguns casos, a concessão encarrega-se do encargo de pagar direito de outorga a algum Pode Concedente. Este trabalho considerou a aplicação dos métodos de avaliação de empresas baseados em Fluxos de Caixa Descontados, Fluxos de Dividendos, Taxa Interna de Retorno, Payback e Múltiplo de Valor como, por exemplo, a relação Valor da Empresa / EBITDA. Os métodos acima foram aplicados na avaliação das cinco concessões de rodovias outorgadas pelo Governo do Estado de São Paulo no leilão público ocorrido em outubro de 2008. Os resultados dessas avaliações, assim como a análise crítica da adequação dos referidos métodos de avaliação, são apresentados no Capítulo V e as conclusões, no Capítulo VI deste trabalho

台灣發行量加權股價指數在編製時並未調整現金股利的影響，不僅會低估實際的投資報酬率，以其作為標竿指標，在評估共同基金績效時，亦會產生標竿錯誤的問題。因此，本文將現金股利的再投資報酬納入，重新編製加權股價指數。實證結果發現，若自民國75年起調整現金股利之影響，則在民國89年10月31日時，股價指數由5544.18點調整為6419.83點，約增加1.16倍。以新指數重新衡量基金績效的結果，發現績效排名並無大幅度的改變，而且基金績效是否擊敗大盤的情形，受新指標的影響亦不大，此乃因近年來上市公司配息少，而且基金績效非常極端。但基於理論上的正確性，在計算投資報酬率及評估共同基金績效時，仍應以納入現金股利之加權股價指數為基礎，以降低因標竿指標錯誤所造成研究結果的偏誤，否則未來我國股票配息的情況及基金報酬率的特性若改變之後，以過去的方式評估績效將可能造成極大之偏差。 / The Taiwan Stock Exchange Market Weighted Index (TAIEX) is not adjusted for cash dividend. Since the TAIEX is commonly used for calculating the investment return of the Taiwan’s market and as the benchmark index for mutual fund performance evaluation, the investment return in Taiwan is underestimated and there is benchmark error in the evaluation of mutual fund performance. This paper adjusts the TAIEX by incorporating the effect of the reinvestment of cash dividend in the TAIEX. The beginning date of our adjustment is January 4, 1986. Since then until the end of October 2000, the adjusted TAIEX grew to 1.16 times of the unadjusted index. However, The mutual fund performance evaluated based on the adjusted index is insignificantly different from that based on the un-adjusted index. This is because mutual funds have extreme performance. Due to the small cash dividend paid out by the listed firms on the Taiwan Stock Exchange, the adjustment effect is not enough to overturn the evaluation of

本論文探討兩稅合一制所增設的兩個機制，即稅額扣抵比率及加徵保留盈餘稅對上市公司股利發放、資本結構以及公司租稅規劃的影響。首先以數學模式推導出兩稅合一制下這兩個機制與股利發放率及負債權益比率之間的關係，再據以建立研究假說，而後進行兩步驟多變量程序之實證測試。研究所獲致的結果包括： 　　一、兩稅合一制實施後，上市公司稅額扣抵比率與總（盈餘）股利發放率呈正相關，且上市公司稅額扣抵比率愈高者，其總（盈餘）股利發放率、現金股利發放率及盈餘配股發放率皆較兩稅合一制實施前高。由於公積配股並不受兩稅合一制實施的影響，故本文也發現兩稅合一制實施前後公積配股率並無顯著差異。整體而言，兩稅合一制實施後，總（盈餘）股利發放率、盈餘配股發放率及公積配股率較實施前減少，而現金股利發放率較實施前增加。進一步的分析顯示現金股利發放率的增加係受到健全股利政策的推行影響，而盈餘配股發放率的減少可能是受到股票股利緩課取消的影響。 　　二、兩稅合一制實施後，符合促進產業升級條例第八條及第九條規定之投資方案，選擇股東投資抵減之公司並無顯著多於選擇五年免稅之公司，可能原因為選擇五年免稅有利於公司現金流量及每股盈餘的金額。此一結果雖與預期方向相反，但也顯示政府原先擔心公司會選擇股東投資抵減而造成鉅額稅收流失的疑慮並未獲得實證支持。但從兩稅合一實施後公司股權結構的變動分析顯示，公司法人持股比率較實施前增加，而僑外投資持股率較實施前減少，支持公司在不同股東身分稅負差距的考量下，會有股權結構移轉之租稅規劃，以降低股東所負擔的稅負。 　　三、兩稅合一制實施後，上市公司稅額扣抵比率愈高者，股東所享扣抵權愈多，則舉債租稅利益愈少，因而總負債權益比率將降低；而上市公司保留盈餘比率愈高者，所課徵的保留盈餘稅愈高，舉債利息的租稅利益反而增加，會造成總負債權益比率增加。本文的實證結果也顯示，兩稅合一制實施後，上市公司稅額扣抵比率愈高者，其總負債權益比率較實施前低；而上市公司保留盈餘比率愈高者，其總負債權益比率較實施前高。 　　綜合本論文實證結果顯示，兩稅合一制實施後，稅額扣抵比率的機制確實其有消除股利所得重複課稅的效益，進而提高公司股利發放的意願，並且有助於公司資本結構的改善。但是，政府對於未分配盈餘加徵 10％營利事業所得稅的規定卻不利於公司資本的累積，反而提高舉債的租稅誘因，也可能抵銷稅額扣抵比率降低舉債的效果，值得政府深入檢討對公司未分配盈餘課稅的不利影響。 / Enacted in 1998, the Integrated Income Tax System has two important features, i.e., the imputation tax credit to shareholders and the 10% surtax levied on undistributed earnings. Using two-step multivariate regression, this study exmines the impacts of these two features on corporations' dividend payout, tax planning, and capital structure. The findings of this study are as follows : 　　1. After implementation of the Integrated Income Tax System, the imputation tax credit ratio is positively related with total dividends payout ratios. Companies with higher imputation tax credit ratios tend to pay out more cash dividends and earnings stock dividends, ceteris paribus. However, there appears no significant relation between the imputation tax credit ratio and capital stock dividends. On average, after implementation of the Integrated Income Tax System, stock dividend payout ratios, including earning stock dividends and capital stock dividends, are decreased, but cash dividend payout ratios are increased. The increase in cash dividend payout may be affected by the balance dividend policy by the SEC, which require corporations to pay out greater proportions in cash dividends. The decrease in earning stock dividends may be due to the cancellation of the deferral of tax on stock dividends. 　　2. After implementation of the Integrated Income Tax System, inconsistent with the expectation, companies still prefer the five-year tax exemption to the investment tax credits. The results suggest that companies' choices are affected more by such factors as corporate cashflows and earnings per shares. However, after implementation of the Integrated Income Tax System, there is a significant change in stockholder structures, with the ratios of corporation stockholders being increased while the ratios of oversea stockholders being decreased. The opportunity of tax arbitrage will have a significant impact on corporations' stockholder structures. 　　3. After implementation of the Integrated Income Tax System, for companies with higher imputation tax credit ratios, their stockholders will have greater tax benefits, and, hence, the tax benefit for companies to use debt financing is decreased. Conversely, companies with higher ratios of retained earnings will bear more tax burdens on the 10% surtax levied on undistributed earnings; therefore, the tax benefit of debt financing is increased. The empirical results support that, ceteris paribus, companies with higher imputation tax credit ratios tend to have lower debt-to-equity ratios, while companies with higher ratios of retained earnings tend to have greater debt-to-equity ratios. 　　In summary, after implementation of the Integrated Income Tax System, the imputation tax credits reduce the double taxation on stockholders' dividend income and, hence, improve corporations' capital structure. However, the 10% surtax on undistributed earnings may result in opposite effect on corporations' capital structure. The findings of this study have important implications for the government to take into account the potential adverse impacts resulted from taxes levied on corporations' retained earnings.

2008年1月1日起員工分紅之會計處理，將與IFRS國際財務報告準則接軌，即員工分紅不再是盈餘分配，而是作為當期的費用；此外，公司以股票作為員工獎酬，原則上亦須以公平價值衡量，並以費用認列入帳。預計此一會計處理之變革，將對公司、股東及員工均產生重大衝擊。而公司為減緩這些衝擊，會產生何種因應措施，即為本研究探討之對象。 由於太陽能產業在近兩三年之EPS及股價高漲。因股價為影響股票獎酬的重要因素之一，因此受員工分紅費用化之衝擊較大，故選擇兩家太陽能電池之上櫃公司為分析及訪談研究之對象，係因獎酬制度的變革對其影響較可明顯觀察。 獎酬員工之態樣甚多，經訪談兩家樣本公司後，兩家公司之管理當局均不希望政策的改變對公司的EPS造成太大的影響，然以2006年度為例，在維持員工原獲配股數不變的假設下，設算修法後對兩家公司在獲利方面分別下降了32%及15%，股東所得亦呈等額下降，員工個人綜合所得稅總稅負有可能最高分別增加161,893千元及29,383千元；而在公司分配之帳列盈餘不變的假設下，兩家公司之EPS分別減少1.5元及0.5元，股東所得降幅分別為9％及3％，員工總所得減少輻度分別為97.2%及97.4%。綜上可見在不做任何因應的情形下，其對樣本公司的EPS影響甚鉅，故兩家樣本公司勢必在此間尋求一個均衡點，修正其目前的獎酬措施，即可能會降低股票的分配比例，相對增加現金分紅的比例。 又以2005年度兩家公司員工紅利實際分配之情形分析，兩家公司員工紅利配股中分別有27％及44％，分配給公司重要管理當局，所以在此波獎酬制度的變格中，公司的管理當局也是重要的受衝擊者。另董事會及高階經理人通常是公司擬訂員工獎酬計畫的重要決策者，如公司利益與其個人利益相衝突時，是否會影響其決定員工獎酬制度的獨立性，是值得深入探討的問題。 在考量各獎酬制度之特性後，及分析整理員工分紅費用化及適用39號公報對個案公司之影響，本研究彙總結論如下: 一、公司應設算決定固定的員工分紅比例，以免超過公司章程所訂定的配比，同時可控制此對公司EPS的衝擊。 二、降低分紅配股之比重，增加現金股利之比重。 三、透過發放現金及發行員工認股權憑證或限制性股票方式，取代部分員工分紅配股。 四、在公司股價較低的時候買回庫藏股再轉讓給員工，以減少對原股東權益的稀釋程度。 本研究對實務提出下列建議： 一、法令規定員工分紅費用化後，應依費用性質列於營業成本或營業費用項下，惟該費用之估列時點與實際員工分紅分配時點可能差距一年半載，其費用性質分類如涉及有資本化之問題時，是否有操弄損益的空間？建議法令規定有更明確之規範。 二、公司的管理當局，尤其是董事會及高階經理人，為擬訂公司員工獎酬制度重要的決策者。在多數董事又身兼公司重要職務的情形下，為避免董事個人與公司、員工或股東的利益相衝突，建議應制訂法令，規範兼任員工之董事於擬訂公司員工獎酬制度時，應予利益迴避，或委由獨立董事來代表研討及擬訂新的員工獎酬制度。 三、39號公報的適用屬估計變動或會計原則變動，依目前對外公告的39號公報版本看，以估計變動的方式來處理，即不追溯調整以前年度的財務報表，此規範適切與否值得探討。 / In order to converge with International Financial Reporting Standard, the accounting treatment for distribution of employee bonus should be considered as current expense and not be deemed as part of earnings distribution starting from January 1, 2008. Besides, share compensation also has to be recognized as current expense using it’s fair value to measurement. This accounting process changed will result in significant impact on the enterprise, shareholders and employee. This study will discuss what kind of approach might be adopted by those enterprises to mitigate this huge challenge. The EPS and share price for those solar energy related industry are increasing dramatically recently. This study decided to select two solar cell IPO companies as sample to interview and analysis the impact on employee compensation scheme changed, due to the impact will be more observable compare with other industries. There are variety types of employee compensation programs. After interviewed, the management of these two sample companies stated that they are not expecting to impact the company’s EPS significantly. By using these two sample companies’ 2006 financial figures as a base, to understand the effect after amendment of the regulation. Under the assumption of non-amended employees’ distributed shares recalculating

The study focussed on the research question namely: “How will the introduction of new ecological taxes impact the South African agricultural sector?” To answer the question, eight international eco-taxes were selected and further investigated. The nature and history of each eco-tax was examined. The effects or expected effects (where implementation have not yet taken place) of the eco-taxes on the agricultural sectors of the foreign countries, were then considered. The study continued by considering the possible impact on South African agriculture, should these taxes be implemented in South Africa. This was accomplished by extrapolating the foreign effects previously investigated. Mindful of findings, recommendations were then made of what eco-taxes could be implemented which will not impede South African agriculture. It was concluded that the British Climate Change Levy and Climate Change Agreement scheme, Australian Carbon Farming Initiative and Swedish meat consumption tax could be considered for implementation. / Financial Accounting / M.

La tesi si propone di rintracciare all’interno dell’ordinamento italiano una regola giuridica, quanto più generale possibile, suscettibile di applicazione al maggior numero di ipotesi in cui un atto giuridico determina l’alterazione di un ordine dato di priorità applicabile a pretese di azionisti e creditori di una società di capitali. Si rileva, infatti, che il diritto vivente delle garanzie reali possa spesso trovarsi in contrasto con un fondamentale principio di diritto dei contratti: quello di relatività dei loro effetti. Vengono, quindi, isolate, due classi di garanzie reali che, al contrario, risultano essere compatibili con il principio richiamato. Una più ampia regola viene, di seguito, proposta, basata sulla stessa logica che fonda l’istituto dei vantaggi compensativi, funzionale a regolare i fenomeni di alterazione di un ordine di priorità, a prescindere dalla natura della pretesa coinvolta. Essenzialmente, quest’ultima regola costituisce la trasposizione nel linguaggio e nel sistema giuridico del criterio di efficienza di Kaldor-Hicks. Dal lato dei diritti patrimoniali e nel prisma dei problemi “ordinali”, vengono individuate decisive somiglianze tra le pretese a titolo di debito e quelle a titolo di capitale di rischio, cosicché viene proposta l’applicazione di istituti classici del diritto azionario (ad es., il diritto di recesso) alla materia dei rapporti di credito. Definito l’ambito di applicazione dei diritti reali di garanzia e riconosciuta la maggior efficienza di strutture del passivo costruite prevalentemente sullo schema della subordinazione invece che su quello della preferenza, si propone di attuare un netto passaggio di sistema dal secondo schema al primo. Lo studio si conclude misurando i risultati ottenuti sugli analoghi fenomeni che si verificano nell’ambito della disciplina del sistema finanziario. / This thesis aims at finding in the Italian legal system a general rule able to provide a guidance for the modification of the order of priority of claims against limited liability corporations. It is argued that the applicable legal approach to security interests could often be in contrast with a basic principle of contract law: relativity. Therefore, firstly, two classes of security interests that proved to be coherent with the aforementioned principle are described. Secondly, a wider rule based on a logic of compensation is put forward and tested on some particular cases. Basically, this rule is a transposition into legal terms of the well-known Kaldor-Hicks criterion. On the economic rights side, similarities are founded between credit claims and equity claims about order issues, so that the compensation rule is thought as applicable, almost equivalently, to both types of claims. Application to a certain class of creditors of “organizational rules” (for example, right of withdrawal) typically provided by law for shareholders is also suggested. Defined the scope of application of security interests and considered the efficiency gains that are achievable by subordination structures instead of priority ones, it is proposed to pursue the same goal of modifying a given order of priority, through subordination agreements. Finally, these results are discussed taking into account some financial law topics.
