人口成長與產業結構的變遷，使得土地使用變更行為的產生，成為一種必然而難以避免的結果。針對有些土地由低價值變更為高價值土地，地主未曾對土地進行任何投資改良，卻獲取大部分變更利得，即所謂社會自然增值部分歸於一已之私。因此，本研究對目前台灣地區土地使用變更利得分配方式予以探究，並試圖提出土地使用變更利得分配模式，作為未來政策施行之參考。 　　為改善現況問題，本研究將土地使用計畫過程區分為四階段：1.計畫構想提出階段；2.計畫擬定階段；3.計畫審議通過階段；4.計畫實施開發階段，將法定程序之變更利得界定在第三階段，此一利得應歸屬社會大眾所有，然而由於實際估算變更後地價不易，因此藉由實際土地使用變更行為（包括開發行為），利用整地後地價反推變更後地價，其中同時考慮投資報酬觀點，透過數學模型的建立來說明土地使用變更利得分配。 　　基於對土地使用變更利得分配現況探討，利用二個個案分析現況與本研究所建立模式差異，認為土地使用變更利得分配比例應以彈性方式處理，透過給予地主（或是開發者）一合理報酬方式，計算實際可拿回可建地比例。實際上，所估算地價的不同，將影響土地分配比例。因此，建議未來應建立完善估價制度，並將土地使用變更利得分配模式予以立法加以規範，且擬訂完整具前瞻性之國土資源分派計畫，使土地使用變更利得分配更為公平合理。

第一篇論述討論處置效果於選擇權市場的實證。處置效果係指投資人在處分資產時，傾向盡快賣出有未實現利得的投資部位，並且繼續持有有未實現損失的投資部位的行為偏誤現象。文獻上有關處置效果的實證多半集中在股票市場而少有於選擇權市場的實證。選擇權市場一般認為是具有私有資訊及較具備金融知識與經驗的投資人會選擇交易的市場。本文實證處置效果在指數選擇權市場上的影響。我們認為對於選擇權投資人來說，價內外程度是最重要且顯而易見的資訊，是很直觀可以衡量可能利得及損失的參考點。相較於傳統衡量根據過去交易價格所形成的未實現損益指標，價內外程度更能吸引投資人的注意力。以本文所提出的基於價內外程度衡量之賣出傾向指標(Moneyness-based Propensity to Sell, MPS)以及根據Grinblatt and Han (2005)所形成的調整後未實現資本利得指標(adjusted Capital Gains Overhang, ACGO)，每周將買權(賣權)排序成五等分後，我們發現持有最高等分的MPS或ACGO的買權(賣權)並賣出最低等分的買權(賣權)所形成的投資組合能夠產生超額報酬，顯示處置效果在指數選擇權市場亦存在。利用雙重排序(double sorting)的方法，我們發現MPS相較於ACGO，是較能夠在選擇權市場捕捉處置效果的指標。第二篇論述討論相似度衡量策略在期貨市場獲利的可能性。文獻上對於技術交易是否能產生顯著的報酬結果並不一致，然而實務上分析過去的價格走勢並使用技術指標所產生的訊號，是廣泛被接受的。現有測試技術交易指標獲利能力的文獻，通常假設投資人在實證測試的樣本期間一致性的參考某個交易指標產生的交易訊號並依此交易。然而實務上投資人可能同時參考不同的交易指標，每次交易可能根據不同交易指標所產生的訊號，且投資人會從歷史交易價格走勢中尋找類似於現有走勢的狀況，以這些歷史走勢接續的報酬率做為現有走勢未來報酬率的預期值。本文中我們提出一個較符合實際狀況的決策過程來描述技術交易投資人的行為，並重新檢視技術交易的獲利能力。我們提出的決策過程包含三個步驟。首先投資人建立一個特徵向量，包含投資人所認為足以預測未來報酬率並足以描述現況的指標。第二個步驟，投資人從過去某段期間中尋找相似於現有特徵向量的歷史狀況，並以這些歷史狀況接續的報酬率來作為預測的根據。最後，投資人依照過去的歷史狀況與現在有多相似，作為接續報酬率的加權權重，並以相似度權重加權平均報酬來做為未來報酬率的預測值，我們將依照相似度加權報酬所產生交易訊號所形成的策略稱為相似度衡量交易策略(Similarity-based trading rules)。我們檢視相似度衡量交易策略在九個不同的期貨市場中的獲利能力，在考量data-snooping及交易成本後，每日相似度衡量交易策略仍在其中六個市場中獲得顯著的報酬率。 / The disposition effect, which refers to the tendency of investors to selling their winning investments too soon and to hold losing investments too long, has been well-documented in the extant literature. However, while empirical researches focus on examining the behavioral bias in the stock market, little attention is paid to the option market, where most informed investors and sophisticated traders gather. This essay tests for the disposition effect on the index options market. We argue that moneyness, the most salient and readily available information for option investors, is a natural reference point for potential gains and losses, which likely attracts market participants’ attention more than traditional measures that are based on past trading prices. Based on the Moneyness-based Propensity to Sell (MPS) measure that we introduce and an adjusted capital gains overhang (ACGO) measure of Grinblatt and Han (2005), we find that a strategy formed by buying calls/puts in the highest MPS or ACGO quintile and selling those in the lowest quintile would generate significant abnormal returns, suggesting the presence of the disposition effect. Using double sorting method, we find that the MPS is better as a measure in capturing the disposition effect on the options market than the ACGO. While the literature documents mixed results for the profitability of technical trading rules, the use of technical buy/sell signals based on analyzing past prices is widely accepted by practitioners. The existing literature on testing the predictive ability of technical trading mostly assumes that a technical investor consistently makes investment decisions based on the buy/sell signals according to one particular trading rule during the entire sample period. However this may be far from reality. Technical investors may simultaneously make predictions based on different technical indicators and follow different technical signals. Furthermore, they analyze historical price patterns that are similar to the current market condition and make assessment of future returns based on the subsequent returns of these similar patterns. The process is known as charting. We attempt to propose a more realistic decision-making process that incorporates the similarity-based predictors to account for technical investors’ decisions in the real world and reexamine the profitability of technical trading rules. The proposed process includes three steps. First, the investor attempts to predict future returns based on a vector of current characteristics that is sufficient for his assessment of the future returns and to depict the present scenario of the stock market. Second, the investor searches for the similar patterns in a specific time window prior to the current date and make an assessment of the future returns based on how similar these past patterns and the current pattern are and how rewarding the subsequent returns of the similar patterns are. Third, the investor is assumed to form a similarity-based indicator which is an assessment of the future returns depended on the similarity-weighted average of all previously observed values of the subsequent returns. The technical investor is then assumed to buy/sell according to the signals generated by the similarity-based trading rules (SBTR). We examine the profitability of the SBTR in nine futures markets and find significantly positive and robust returns after considering the data-snooping adjustments and transaction costs in six of the nine markets.

近年來我國屢次爆發掏空公司資產之弊案，而細究其掏空之方式，多係藉由公司之交易行為，將公司資產不法輸送予特定人士。我們不難發現這些特定人士時常某程度與公司之董事或控制股東，具有一定之利害關係，甚至這些特定人士即為董事或控制股東本身。正因如此，關係人交易在我國公司治理議題上逐漸受到重視，並引起廣泛之討論，尤其針對具有董事或控制股東身分之人。由於此兩類身分之人同時具有掌握公司資訊及影響公司經營決策之權力，更易藉此方式自公司謀取私利。 我國對於關係人交易下董事之義務，雖已有規範，然而自比較法之觀點，美國法對此部分顯然較我國完備，不僅對於關係人交易設有事前之董事行為標準，並且對於符合行為標準之關係人交易，給予董事安全港之保護。同時，配合司法實務上所發展之司法審查標準，採取寬嚴不一的審查模式，使董事得於關係人交易中合理預測訴訟風險。一方面可降低關係人交易中非常規交易發生之可能性，另一方面亦不至於全然扼殺關係人交易在現代經濟社會中產生之正面價值。我國法之董事義務既是繼受英美法上受任人義務之概念，因此本文嘗試分析美國法中關於關係人交易之相關規定，希冀做為我國修法之參考以求法制之完備。 又我國現行公司法在控制股東義務方面，似存在重大之法律漏洞。尤其在關係人交易下，有心人士為規避擔任董事可能帶來之相關義務，轉而選擇置身於幕後，成為不具董事身分卻實際掌握公司經營決策權之控制股東。此無疑對於欲利用關係人交易不法掏空公司之人，開啟方便之大門。事實上，在英國及美國法上對於控制股東在特定情況下課予如同公司董事一般之受任人義務，而本文則將其焦點限縮在關係人交易下控制股東之義務，經由整理分析英美兩國法制上之條文、學說及重要判決，以期建構出我國規範關係人交易下控制股東義務之依據。

我國經濟犯罪之範圍，係由司法機關(司法院)與行政機關(法務部) 分別以作業性之行政規則頒訂，仍以侵害個人財產法益之金融犯罪為 規範對象。 就經濟犯罪所得，由於其性質屬於準不當得利之衡平措施，自應予以 追繳或抵償(再發還被害人或充公收歸國有)以修復正義，該行為只要 與法規範對立矛盾(即具有不法構成要件該當之違法性)即足，無庸探 究行為人之罪責要件。我國將犯罪所得規定為從刑，須待行為人(即 被告)受有罪科刑判決方能併宣告沒收，緩不濟急。 建議將犯罪所得追繳後發還被害人之個別法律，移置於刑法總則一體 適用，定性為強制處分，並將沒收、追繳、追徵或抵償自從刑之規定 刪除，另於刑事訴訟法宣示判決之條文增加發還被害人或得請求損害 賠償之人，且得由法院依職權或依檢察官之聲請權單獨宣告。 我國附帶民事訴訟受請求之被告，不限於刑事訴訟進行中之被告，尚包括「其他依民法應負賠償責任之人」，刑事庭法官遇有此種情形，因對渠等並無確定刑罰權有無及範圍之權限，在刑事訴訟程序的操作上格格不入，有仿襲德國刑事訴訟法第403條規定，被請求人應以刑事被告為限。 由於附帶民事訴訟規範之目的在避免雙重工作負擔及二次裁判，惟依 現行刑事訴訟法之規定，法官除刑事判決外，另需製作一份民事訴訟 判決，如此顯違反前揭附帶民事訴訟規範之目的；故正本清源之道， 乃無庸另製作一份附帶民事訴訟之判決，就犯罪不法利得，逕於刑事 判決主文中諭知發還被害人或給付若干金額予被害人。 被害人與加害人間共同參與之修復式司法近年來在世界各國實務及 學說均肯定其實踐層面之重要性，為具體落實憲法訴訟權應保障犯罪 被害人公平且有效的權利救濟途徑及程序主體性之地位，本文建議在 審理刑事案件之前階段即擴大強制調解及和解制度之運用，由被告及 被害人共同參與決定採取何種途徑最有利於促成實質修復正義之結 果，俾利被害人程序主體性之建立及擴大紛爭解決一次性之要求。 / Economic crime in Taiwan is defined by the administrative regulations of the Judicial Yuan and the Ministry of Justice, respectively. Such regulations are aimed at financial crimes that damage personal property. Because the proceeds of economic crimes are “quasi-kondiktionelle Ausgleichsmaßnahme”, the courts should seize the profits, and then use them to either compensate victims or confiscate them in the name of serving justice. So long as this offense is contradictory to criminal law (i.e. constituting the penal code and finding no specific legal cause for that offense), the courts need not review the problem of offender's guilt. As ill-gotten gains are stipulated as “Nebenstrafe” in the Taiwan penal code, the courts cannot confiscate those gains unless there is a simultaneous conviction, which seems too slow. The following suggestions are presented. The individual laws regulating “Verfall” and compensation to the victims should be reorganized in the penal code and characterized as “maßnahme”. The legal effect of these laws as “Nebenstrafe” should be deleted. The articles relating to the compensation of criminal proceeds to the victims should be increased as well. In addition, the courts should be allowed to announce verdicts either alone by its authority or according to the prosecutor’s request. In Taiwan, defendants accused during the adhesion process are not limited to being defendants in the process of criminal litigation, but also include other persons who should bear damages in accordance with civil law. When criminal court judges face this situation, since it is not certain whether there is a right to impose criminal punishment, or what the scope of punishment should be, there are inconsistencies in the operations of the criminal litigation procedure. There have been attempts to imitate Germany’s Criminal Litigation Law Clause 403, in which the accused should be limited to criminal defendants. The purpose of the rules on the adhesion process is to prevent a double workload and multiple judgments. However, according to existing requirements for criminal litigation, in addition to criminal judgments, judges must also make civil litigation judgments. This violates the aforementioned purpose of adhesion process rules. Thus, the way to rectify this situation is to create another adhesion process judgment based on the proceeds of crime, in order to assign restitution or to pay a certain amount to the victim, inside the main text of the criminal judgment. Restorative justice, in which the victim and offender jointly participate, has recently been affirmed in its importance, both in theory and in practice, all over the world. In order to concretely realize the principle that constitutional litigation rights should protect crime victims, as well as provide fair and effective remedial paths and procedural subjectivity, this study suggested that in the stage prior to judging criminal cases, there should be expanded use of enforced arbitration and mediation systems, in which the defendant and the victim jointly participate, in order to determine the best course for promoting restorative justice, to satisfy the demand for victim procedural subjectivity, and to expand the one-time character of dispute resolutions.

在效率市場支配財務理論數十年後，市場上發現許多違反傳統訂價理論與理性假設的現象，以心理學為基礎的行為財務學因而掘起，將投資人之主觀行為及心理因素納入決策分析之考量。本研究便是以台灣股票型共同基金為研究對象，探討行為財務學中的錯置效果，了解是否台灣之股票型共同基金存在“急售利得，惜售損失”的現象。 / 本研究首先以Odean模型之概念，計算基金投資之已實現利得比率與已實現損失比率，再用兩者之差形成錯置效果之代理變數：Disposition Spread (DISP)，當DISP為正時，表示樣本基金存在錯置效果傾向，偏好實現利得。接著計算基金之Jensen’s Alpha，用以代表基金績效，利用迴歸模型觀察基金績效與錯置效果間之關聯性。最後再進一步透過DISP分成五級，觀察錯置效果是否存在持續性。 / 研究結果發現，台灣的股票型共同基金不存在錯置效果之傾向，不論是整體基金而言，或是分類觀察之，皆不存在錯置效果之傾向。但是總樣本觀察值中，有33%的比例出現正的DISP值，因此無法斷言共同基金完全不受錯置效果之影響。而錯置效果與基金績效間，則是存在顯著的負相關，即錯置效果越明顯者，其績效表現越差。普遍而言，台灣股票型共同基金錯置效果不存在顯著的持續性，每一期的基金DISP在各分級變動機率均約在20%上下。 / For several decades, financial literature was dominated by the idea of efficient market. However, we can find many phenomena which violate traditional pricing model or the hypothesis of rational investors. That’s why behavioral finance arises. Behavioral finance takes investors’ subjective and mental factors into account while talking about their decision making process. Based on behavioral finance, this study examines the disposition effect of Taiwan equity mutual funds. We want to know if Taiwan equity mutual funds appear to realize gains more readily than losses. / This study follows Odean model analyzing disposition effect by first calculating proportion of gains realized (PGR) and proportion of losses realized (PLR) of equity mutual funds. Then form the disposition effect proxy, Disposition Spread (DISP), by measuring the difference between PGR and PLR. While positive DISP existed means that sample funds exhibit a propensity to sell their winning stocks and hold on to their losers. Furthermore, we want to know whether the disposition effect influences the performance of mutual funds. Finally, separating samples in to five groups by DISP, we want to figure out if funds exists consistency in disposition ranking. / On average, mutual funds appear to realize losses more readily than gains. However, about 33% of the sample observations exhibit disposition effect. The disposition effect is negatively related to fund performance. Generally speaking, Taiwan equity mutual funds do not have consistency in disposition ranking.
