本論文為探討台灣國際觀光旅館產業的實證文章，除第一章的緒論外，三篇相關的文章依序撰寫於二至四章。第二章的實證結果指出在第一階段的未考量準固定與調整後投入的資料包絡分析模型會高估技術與純技術效率值，但會低估規模效率值，因此，驗證考量準固定投入的必要性；第二階段使用隨機邊界分析模型排除外在因素與隨機干擾的影響，實證結果顯示外生變數對投入差額與純技術效率存在顯著的影響，其中，市場集中度與旅館規模對勞動、餐飲支出與其他支出的投入差額存在正向的影響，對純技術效率存在負向的影響；位於風景區對所有的投入差額有負向的影響，對純技術效率有正向的影響；加入國際與/或國內連鎖對勞動與餐飲支出投入差額有正向影響，但對其他支出投入差額有負向影響；SARS對勞動與餐飲支出投入差額有正向影響，對純技術效率有負向影響；金融海嘯對勞動與其他支出投入差額有正向影響，對純技術效率有負向影響；第三階段的效率評估結果顯示技術無效率的主要原因是來自不適當的生產規模，且國際觀光旅館對於技術與規模效率仍有改善空間，此外，傳統的資料包絡分析模型會高估技術與規模效率值，但會低估純技術效率值，因此，驗證使用三階段方法的適當性，最後，以服務團體旅客為主的國際觀光旅館的績效最差。第三章的實證結果顯示：在第一階段，未考量準固定與調整後投入要素的Malmquist生產力指數會低估生產力的變動，因此，驗證考量準固定投入的必要性；第三階段的生產力指數顯示前期的生產力成長已被後期的生產力惡化所取代，生產力的成長或惡化主要來自技術的進步或退步與規模效率的改善或惡化，此外，實證結果亦顯示僅考量準固定投入但未考量調整後投入的Malmquist生產力指數會低估生產力的變動，且是否考量調整後投入會造成所評估的Malmquist生產力指數其背後的因素有所不同，因此，驗證使用三階段方法的適當性；最後，以服務團體旅客為主的國際觀光旅館的生產力有較佳的改善，且雖然服務對象的不同使得生產力變動的背後因素有所不同，但規模效率的變動皆扮演重要的角色。第四章的實證結果顯示：規模效率假說在台灣國際觀光旅館產業中是被支持的；以服務個人旅客為主與同時服務團體與個人旅客對獲利率有負向的影響；SARS與金融海嘯對獲利率有負向的影響。 / The dissertation is a collection of three separate but related papers which are devoted to the empirical studies of the international tourist hotel industry in Taiwan. In addition to the introduction in chapter 1, three papers are presented in chapters 2 to 4, respectively. The empirical results in chapter 2 indicate that, in the first stage, the data envelopment analysis (DEA) models without the quasi-fixed and adjusted inputs overestimate the technical and pure technical efficiencies, but underestimate the scale efficiency of international tourist hotels so that the necessity of considering the existence of the quasi-fixed input is justified. The second stage uses the stochastic frontier analysis (SFA) model to purge the effects from exogenous variables and statistical noise. The SFA results show that the exogenous variables have significant influences on input slacks and pure technical efficiency. The degree of market concentration and hotel size have positive impacts on labor, food and beverage (F&B) expense and operating expense input slacks, as well as have negative impacts on pure technical efficiency. An international tourist hotel in the resort area has negative relationships with all input slacks and a positive relationship with pure technical efficiency. An international tourist hotel participating in the international and/or domestic hotel chain has positive relationships with labor and F&B expense input slacks, but has a negative relationship with other expense. Severe acute respiratory syndrome (SARS) has positive effects on labor and F&B expense input slacks and has a negative effect on pure technical efficiency. The financial tsunami has positive effects on labor and other expense input slacks and has a negative effect on pure technical efficiency. After adjusting the variable input data from the SFA results in the second stage, the efficiency-evaluation results in the third stage show that the technical inefficiency mainly results from the inappropriate production scale. In addition, international tourist hotels have an ample space to improve their technical and scale efficiencies. The efficiency-evaluation results also show that the conventional DEA models overestimate the technical and scale efficiencies, but underestimate the pure technical efficiency of international tourist hotels so that the usage of the three-stage approach is justified. Finally, international tourist hotels which mainly receive group visitors have the worst performance. In chapter 3, the empirical results show that, in the first stage, the Malmquist index without the quasi-fixed and adjusted inputs underestimates the productivity change so as to justify the necessity of considering the existence of quasi-fixed input. After adjusting the variable input data from the SFA results in the second stage, the productivity index in the third stage shows that the initial increase in productivity has been compensated by a decrease. The productivity growth or deterioration mainly results from the technological progress or regress and the scale efficiency improvement or deterioration. The results also show that the Malmquist index with the quasi-fixed input and without adjusted inputs underestimates the productivity change. The key factors of the productivity changes estimated by the Malmquist productivity index with the quasi-fixed and adjusted inputs are significantly different from those estimated by the Malmquist productivity index with the quasi-fixed input and without adjusted inputs so as to justify the usage of the three-stage approach. Finally, international tourist hotels with mainly receiving group visitors have the better improvement of productivity. The sources of productivity changes among receiving different types of visitors are different, but the scale efficiency change plays an important role in all types. In chapter 4, the empirical results indicate that the scale efficiency hypothesis is supported in Taiwan’s international tourist hotel industry. An international tourist hotel that mainly receives individual visitors and an international tourist hotel that simultaneously receives group and individual visitors have negative impacts on profitability. SARS and financial tsunami have negative effects on profitability.

目前全球的金融衍生性商品市場中，利率衍生性商品占了全球衍生性商品交易量的一半以上，其次為匯率衍生性商品。市場上的結構型商品，有的連結數個標的，有的報酬型態複雜，不易為一般投資人所了解，且投資人容易被商品條款上的高配息或最高報酬率吸引，而忽略了對投資人不利的條款。 本文針對目前金融市場上已發行的利率及匯率連結金融商品，進行個案評價與分析，希望能讓一般投資人更了解市面上結構型商品的報酬型態，以及潛在的投資風險，並站在發行商的角度，進行商品利潤分析及發行策略的探討。 本文所評價的兩個商品為英國勞埃德銀行(Lloyds TSB Bank Plc.)所發行的「每日計息雙區間可贖回債券」和中國農民銀行所發行的「觸及失效匯率連結債券」，分別以LIBOR Market Model (Brace, Gatarek and Musiela,1997，也稱為BGM模型)和三元樹模型(Ritchken,1995)對其進行評價。最後針對評價結果分析發行商的發行策略以及投資人需注意的投資陷阱。

本文採用Lognormal Forward LIBOR Model (LFM) 利率模型，針對可贖回雪球式債券進行相關的評價與避險分析，而由於此商品的計息方式為路徑相依型態，價格沒有封閉解，故必須利用數值方法來進行評價。過去通常使用二元樹或三元樹的方法來評價具有可贖回特性的商品，但因為LFM是屬於多因子模型，所以不容易處理建樹的過程。而一般路徑相依商品的評價是使用蒙地卡羅法來進行，但是標準的蒙地卡羅法不易處理美式或百慕達式選擇權的問題，因此，本研究將使用由Longstaff and Schwartz(2001)所提出的最小平方蒙地卡羅法，來處理同時具有可贖回與路徑相依特性的商品評價並進行實證研究。 / 此外，關於可贖回商品的避險參數部分，由於商品的價格函數不具有連續性，若在蒙地卡羅法之下直接使用重新模擬的方式來求算避險參數，將會造成不準確的結果，而Piterbarg (2004)提出了兩種可用來計算在LFM下可贖回商品避險參數的方法，其實証結果發現所求出的避險參數結果較準確，因此本研究將此方法運用至可贖回雪球式利率連動債券，並分析各種參數變化對商品價格的影響大小，便於進行避險工作。

近年來知名公司面臨起訴或遭到定罪的消息層出不窮，然而在公司定罪的相關研究中，多數文獻著重於探究遭受定罪之事實對公司價值的影響，較少研究聚焦於定罪事實對公司所參與之聯貸案契約條件的影響，有鑑於此，本篇文章旨在探討犯罪公司於定罪前後其聯貸借款條件之借款利率是否有顯著差異。本篇研究發現事件前後犯罪公司之借款利率差異並不顯著。當我們試以修正資料庫登錄與犯罪新聞時間差的問題後，結果顯示犯罪公司之借款利率於犯罪相關新聞發布後顯著上升，除此之外，考量交乘作用後發現犯罪公司間，犯罪罪刑為詐欺類以及受判罰金較高的犯罪公司於事件後，相較於其他犯罪公司，該類公司更傾向面臨較高的借貸成本。 / A number of well-known corporate prosecutions have been raised in recent years. Previous literature focuses more on the valuation impact of corporate convictions. Empirical evidence on how corporate convictions affect the contract terms of syndicated loan is sparse. We examine how corporate misconducts affect the pricing of bank debt after corporate convictions. We find that the difference of loan spreads between facilities initiated before and after conviction are insignificant. Taking potential lag of initial announcement time into consideration, we find significant evidence that the effect of corporate conviction is positively associated with the increases of loan spreads. Moreover, interaction terms with conviction variable show that firms with large fines or convicted of fraud-related crimes tend to face higher loan spread after convictions.

近年來，政府會計之改革為各國探討之議題，本研究探討當政府公部門財務報告採用國際會計準則編製，並且經過獨立審計機關查核後，對其發行公債之殖利率利差之影響。本研究從英國債務管理辦公室及倫敦證券交易所之資料庫，蒐集英國中央政府發行公債之資訊，以 2006 年至 2014 間有交易行為之公債為樣本，進行迴歸分析。結果顯示，公債殖利率利差與採用國際會計準則呈現顯著負相關，意即政府報表採用國際財務報導準則，會使市場投資人獲得更透明之財務資訊，而預期公債之無法償還風險降低，且更加願意投資公債。除此之外，當政府提供依國際財務報導準則編製之政府財務報告，再經過會計師查核，審計效果與殖利率利差亦呈現負相關。敏感性測試則指出，當不考慮金融危機的非常規狀況時，同樣可以顯示出相同結果。 / The reform of government accounting systems has become a trend in many countries during recent decades. This study investigates the effect on sovereign bond yield spread of adopting IFRS in government sector, and how yield spreads might be affected after financial reports are audited. Data of tradable UK sovereign bonds are collected from UK Debt Management Office and London Stock Exchange for the period of 2006-2014. Based on the results of regression analysis, the adoption of IFRS by UK governments is negatively associated with gilt bond yield spreads, which means sovereign risk is perceived to be lower by the investors after the adoption of IFRS by central government. When the IFRS-based government financial reports are audited, negative connections between audited reports and yield spreads provide further evidence that investors show higher faith in the sovereign bonds. Additionally, the results remain the same when data of 2009, an abnormal year because of world financial crisis are added back to the regression.

借款公司與銀行間彼此往來關係以及議價能力是否是決定聯合貸款契約中依績效調整利率條款內容的重要因素? 本研究嘗試利用1993至2010美國聯貸案之資料來檢視此一關係是否確實存在。 實證結果發現，當借款公司與銀行已有往來關係且公司之籌資選擇較少時，會比較傾向簽訂利率向上調整之績效條款。此外，由於單一主辦行於聯貸案中無法向借款公司剝削所有利益，因此對於已和借款公司有往來關係的主辦行來說，其較不傾向簽訂利率向上之調整績效條款。最後，本研究發現，對於主辦行排名較後面的銀行來說，其更傾向簽訂利率向下之調整績效條款來吸引客戶(借款公司)。 / It is shown in this thesis that long-term banking relationships and bargaining power are important determinants of performance-pricing covenants (PPC) inclusions in syndicated loan contracts. Using a large sample of syndicated loans data (1993-2010), I find that syndicated loans tend to include more interest-increasing PPC when a long-term banking relationship exists and when borrowers have fewer financing alternatives. The presence of banking relationship with lead arrangers reduces the odds of using interest-increasing PPC, because lead arrangers might not be able to capture all rents from holding-up borrowers. Finally, I find lenders with lower league table ranking are likely to use more interest-decreasing PPC to attract borrowers, which again is consistent with the hold-up hypothesis.

財務報表為制訂授信決策之重要資訊來源，而穩健會計可增加公司財務報表的資訊品質。本研究實證探討當公司採行穩健會計時，是否可降低銀行融資超貸之可能性，使銀行願意為了穩健財務報表的效益，而降低公司需支付的債務融資成本。 本研究以1997至2008年之5,507筆觀察值為研究樣本，依Beaver and Ryan（2005）之分類，將穩健會計衡量指標分為非條件式穩健會計與條件式穩健會計，分析公司會計穩健程度對銀行融資利率的影響，並探討公允價值會計是否會影響條件式穩健會計與銀行融資利率之關聯性。 本研究之主要實證結果顯示，非條件式穩健會計與條件式穩健會計皆與銀行融資利率呈負向關係；公允價值會計之採用與銀行融資利率呈負向關係，且正向影響條件式穩健會計與銀行融資利率之關聯性。非條件式穩健會計與銀行給予融資超貸之風險呈負向關係，但條件式穩健會計與銀行給予融資超貸風險之關聯性並不一致。額外之測試顯示，主要實證發現不因改採其他方式衡量銀行融資利率，或以稅前息前淨利取代稅前息前折舊前淨利衡量超貸風險而有改變。 / Financial statement is one of important resources to credit decisions making. Conservatism increases the quality of financial statement. Based on the definition of types of accounting conservatism, unconditional and conditional, proposed by Beaver and Ryan (2005), and the use of a sample of 5,507 firm-year financial data from 1997 to 2008, this study investigates conservatism effects on the over-loan risks from borrowers through bank loan pricing. The primary empirical findings indicate that a significantly negative association exits between unconditional (conditional) conservatism and bank loan pricing. In addition, a significantly negative association exits between fair-value accounting and bank loan pricing, and the adoption of fair-value accounting affect the association between conditional conservatism and bank loan pricing. Moreover, the result also shows that a significantly negative association exits between unconditional conservatism and the over-loan risks. The analysis of additional tests indicates that the primary findings held when alternative measurements of interest rates are used for proxy variables for bank loan pricing and EBIT is used for proxy variables for EBITDA.

本文考量於Excel介面下設計一「壽險公司現金流量模型」，透過保險財管、精算理論的採用與大量隨機模擬亂數的應用，欲建構一結合理論基礎與實務運用的動態財務分析系統雛形。 模型中，資產面的模擬項目共有七項：1.債券與放款：採用CIR或Vesicek兩利率模型供選擇進行利率期間結構生成，以模擬出各到期期限的債券及放款價格。2.股票：以資本資產訂價模型(CAPM)來模擬各類股股票價格的變動與股票投資報酬。3.不動產：使用幾何布朗運動模擬不動產價值與租金收入。4.國外投資：利用幾何布朗運動模擬匯率的變動。5.現金及銀行存款。6.應收款項，考量壞帳情況下，逐年比率攤回殘餘金額。7.其他資產。 負債面採用定期險、終身生死合險與遞延年金險模擬壽險公司業務經營的現金流量情況。藉由資產與負債的整合，可模擬出公司未來十年內各年度的損益情況，讓使用者了解於承受總體經濟各項不確定風險下，壽險公司資產面、負債面與業主權益的現金流量情況。 文末引用個案範例，進行實務操作的說明，示範如何應用本模型來進行最適資產配置決策與敏感度分析，以證明本系統的合理可行性。最後，並對此系統提出檢討與展望，期待後續研究可加入程式語言的應用而建構出一完備的動態財務分析系統。 / The main purpose of this study is to construct a dynamic cash flow testing for the life insurance company by using Excel. Through the adoption of financial and actuarial theories and the application of stochastic method, we want to provide a rudiment analysis framework of life dynamic financial model that combines theoretical basis and practical application. This analysis framework includes seven categories of assets. The simulation models or related issues for each category will be discussed accordingly. – 1. Bonds and mortgage loans: providing CIR and Vesicek interest rate model for users to generate the interest term structure. 2. Stocks: applying CAPM method to simulate the stock prices and stock returns. 3. Real estate and rental income: using Geometric Brownian Motion to simulate the price of real estate and the rental income. 4. Foreign investment assets: using Geometric Brownian Motion to simulate the movement of exchange rate. 5. Cash and Deposits. 6. Account Receivable: after considering bad loans, we amortize the residual account receivables for a specific period. On the liability side, we use three types of products - term life, whole life endowment, and deferred annuity - to generate the business profile as well as the cash flows patterns of the life insurance company. By integrating the asset and liability sides of the model, we can simulate the revenue of the company for the following ten years and enable the users to predict the future cash flows under uncertain financial conditions. Finally, applications of this model are presented as thoroughly as possible to educate the users about how to make the optimal asset allocation decisions and sensitive scenario analysis. The application results show that the model reasonably fits the desired results. Since the model presented here is not a complete DFA model, future researches may consider adding more refined component into the analysis framework like using programming language.

連動式債券已成為目前市場上最熱門的投資工具，標榜著高受益的條款下，常隱含著投資人所不瞭解的風險，利用理論的模型套用在實務商品上，可以令人更清楚認識複雜化的金融衍生性商品。本文在Libor市場模型與Hull-White利率模型的架構下，利用數值方法評價分析最常見的兩種連動式債券－固定期限利率交換利差連動債券與信用連結債券。 Libor市場模型直接拿取市場上可觀察到的遠期Libor利率做為模型的標的，有良好配適目前利率期間結構的優點。利用此模型為出發，校準出波動度期間結構，以蒙地卡羅模擬法來評價固定期限利率交換利差連動債券。由評價結果可量化分析出連動式債券內含的選擇權與零息債券價值為何，探討發行商的發行策略與投資人的風險來源。 繼股權、利率連動式商品之後，未來金融商品的連動標的將進入信用風險的階段。以公司債的市場資料建立出一條信用風險曲線(Credit Curve)，最能夠反映出當時市場上大多數人對於未來發生違約事件的預期。在假設利率市場風險和標的公司信用風險是獨立的前提下，將這條曲線和以Hull-White利率模型為基礎建立的利率三元樹與路徑函數結合，便可以適當地評價信用連結債券的價值。最後，求算債券內含的信用違約交換價值，對發行機構的策略與投資人的風險作分析。

經由愈來愈多的實證研究發現，的確在利率的變動過程中，除了包含連續性行為，即遵循”擴散”模式(diffusion process)，亦包含了不連續性行為，也就是有著跳躍(jump)的情形發生。因此顯示出假設利率隨機過程僅為連續性的擴散模型已是不足夠的，跳躍-擴散模型(Jump-diffusion model)顯然會比純粹擴散模型有著更好的解釋能力。而市場模型(LIBOR market model)的提出，則說明了遠期LIBOR利率模型較能描述市場實際的利率型態，並且可方便使用市場資訊，進行模型參數校準。 所以本研究旨在以LIBOR market model 加上跳躍過程，即遠期LIBOR利率的跳躍-擴散模型，分別針對歐洲美元期貨與利率結構型債券中的滾雪球式累息債券建立評價方法。由於所選用動態模型的複雜度，使得封閉解的求出不易，因此在文中，最後是採用蒙地卡羅模擬法，求兩商品的數值解。在後續研究上，本文還挑出了幾個最直接影響商品價值的因素，如殖利率、波動度、跳躍幅度等，進行各種情境下商品價值的敏感度分析，以提供投資人與發行商在考量風險因子所在時的一個參考。
