外資交易行為是否誤導散戶投資行為下單? / Do foreign investors' trading behavior mislead individuals' investment?

姜珮瑜 Unknown Date (has links)
本研究主要目的是檢視外資的買賣超資訊是否能為散戶投資人帶來有用資訊,進行跟隨買賣而獲利? 再者,以34家公司樣本為例,觀察外資對某股欲大量買賣超時,經由買賣單的下單積極性分布情形,是否有藉此誤導散戶投資人投資行為的嫌疑?實證結果發現,跟隨外資買進金額買超最大的標的股,確實能為散戶投資人帶來獲利,但若跟隨買超張數最大而買入標的股,獲利幅度會下降。而跟著外資大量賣超而殺出的標的股,不論賣出張數最大或賣出金額最大,散戶投資人未有較高獲利可以獲得。最後,實證發現外資對在欲大量買超或賣超的標的股中,均會以積極性高的下單價格來使其買單或賣單快速成交。但外資大量買超下的賣單比例以及大量賣超下的買單比例下單於積極度最差的價格區間均有高於正常樣本期間的情況發生。 / The main purpose of this study is to examine Taiwan's 34 major companies trading over information for retail investors is to bring useful information to profit following foreign investors’ buy-sell information. Furthermore, this observation of 34 companies to buy-sell ultra -volume, the order distribution of buy and sell would give wrong information to mislead retail investors? The result shows if retail investor follow foreign investors’ step to buy the maximum market share and volume underlying stock can bring abnormal return than market return and industry return, But if retail investors follow foreign investors’ selling behavior not to take extra return from mimic trading behavior. Next, analysis of foreign investors’ trading behavior is consistent or not? We find if foreign investors really want to buy or sell the underlying stock, their buy-order and sell –order will set at the best price to make it a deal quickly , but one the other hand, we find their sell-order and buy-order will set the price which less possible to make this transaction.

外資買賣短期市場衝擊與長期績效之研究

田慧琦 Unknown Date (has links)
本研究主要討論外資買賣對市場短期衝擊及外資長期績效的評估。在短期市場衝擊部分,利用VAR模型檢定外資買賣超對股市報酬率的影響,並以GARCH模型,檢定外資買賣超波動是否顯著影響股市波動。在評估外資投資表現方面,本文不僅就外資額著增減所投資個股持股比率時,觀察買入與賣出個股前、後的平均累積報酬率變動情形,對應外資可能的投資期長衡量其擇股及擇時能力,同時,亦針對外資投資對象的規模加以區分,檢測外資的投資表現是否因個股規模而異。 目前媒體相當重視外資在股市活動,雖然不論外資就匯入金額占股市市值比重或外資在股市買賣金額占市值比重,均有日益上升的趨勢,但在股市的規模仍然偏低,比重尚不及5%,惟外資或有指標效果,藉由帶動投資人買賣,對股市造成衝擊。本文VAR及GARCH模型檢定獲得一致結果:前期外資買賣對股市報酬率及股市報酬率波動的影響顯著。既有短期市場衝擊投資人似乎頗重視外資訊息,對於外資交易的參考價值有必要進一步檢測。本文觀察外資買、賣股個股前、後的累積報酬率,發現外資表現優於市場表現。其績效不僅為經濟顯著,亦為統計顯著。本研究利用相關係數及Treynor與Mazrya模型檢定發現外資具顯著擇時、擇股能力,對投資決策,具有參考價值。分析不同規模個股外資表現的結果顯示,外資似乎較擅長投資規模較大的股票,對規模小的股票表現較差。

國際商品買賣有關品質條件之研究

黃文龍, HUANG, WEN-LONG Unknown Date (has links)
鑒於一般國際商品買賣的索賠糾紛中,以品質不良或不符合的索賠被認為是關鍵問題 ,且亦佔最大比例,故本文乃針對國際商品買賣有關品質條件諸問題作一重點式探究 ,惟文中未涉及有關『製品責任』問題。文分六章,共十萬餘言,茲列各章內容如左 : 第一章:緒論。說明研就動機、目的、範圍及方法。 第二章:決定品質條件的基本事項。說明品質與品質條件的意義,並對決定品質條件 的標準與時地作一介紹。 第三章:出賣人有關品質的暇疵擔保責任。說明暇疵擔保責任成立的要件與範圍。 第四章:出賣人有關品質暇疵擔保責任的排除與限制。詳述中、美、英等國法律之規 定,並探討有關品質之免責條款在國際貿易上之應用。 第五章:商品的檢查、受領與品質習疵的救濟。分析買受人商品檢查權的性質及檢查 時地、方法、費用等問題;並針對品質暇疵買受人所能獲得的救濟方法做一概述。 第六章:結論與建議。以預防品質糾紛之道作本文結論。 本文探討主要以買賣契約品質條件的訂定,由此而引發出買賣雙方權利、義務的關係 ,惟在國際買賣通常都有第三者(如船公司、保險公司等)的介入,益使買賣雙方權 利、義務關係更形複雜,本文為求簡化,對於第三者的介入皆視為買方或賣方之履行 輔助人,其實任直接歸宿到買賣雙方當事人,故未作進一部探究,尚有待學者先進補 充指正。

從傳統民法解除權到特種買賣解約權

游楨德 Unknown Date (has links)
傳統的民法理論與規範架構中,得以解除契約或行使撤銷權,乃基於立法者對於傳統私法體系下,擬欲維持私法自治原則及契約制度嚴格遵守之例外,其要件限制多較嚴苛。然則,在現代社會之消費關係,隨著大量生產下的經濟發展等演變,消費者與企業經營者間,其專業知識、經濟力及交涉力則常處於不均衡之地位,在消費者面對無店舖銷售及業者強力新穎勸誘的行銷衝擊下,傳統民法解除權之機制,似乎很難有效彌補消費者於交易中弱勢地位,使得消費者的權利受到完整的保障。 因之,本文擬先以民法上解除權及撤銷權之相關規範作探討,並進一步檢討消費者無條件解約權之法理、進展及其相關重要規定。此外,消費者之解除權立法後之執行成效及若干問題,亦值得關注。例如,消費者解約權之期間長短、起算期間、數位化商品及企業經營者違反告知義務之法律效果等,似有若干問題仍困擾著消費者與企業經營者,本文擬一併討論之。 最後,本文亦擬透過詳細的分析與檢討,針對消費者無條件解約權的法規範,提出改善建議。並嘗試對現行民法與消費者保護法之立法模式,提出建議,期能對現行相關問題,尋找更佳之解決途徑。

訪問買賣規範及爭議問題之探討 / The statutory issues on door- to- door sales

呂惠珍 Unknown Date (has links)
訪問買賣之消費糾紛有逐年增加之趨勢,然而國內研究文獻卻相當稀少。本論文嘗試以較宏觀之角度,整理歸納學說理論及實務見解,並與外國法進行比較分析,藉以檢討現行法規範及提出修正建議。 第一章「緒論」:本論文之研究動機與目的在於探討實務上訪問買賣常見之糾紛類型,並依消費者保護法規範之體系,從定義、適用範圍、企業經營者之告知義務、消費者之解除權逐次展開,檢討現行法是否足以預防或解決問題?主管機關或司法判決對於訪問買賣有何發展性之見解?外國法制對於類似行銷方式之規範,是否有值得我國借鏡之處?期本文之初步探討能拋磚引玉。   第二章「訪問買賣之規範」:介紹我國消費者保護法及其施行細則、定型化契約應記載事項與範本、地方消費者保護自治條例等有關訪問買賣相關規範;外國法部分主要介紹與我國法制淵源較深之德國及日本相關規範,其餘主要國家法規範摘要則列為附錄。   第三章「訪問買賣定義及適用範圍之檢討」:由於消費者保護法對於訪問買賣之定義及適用範圍不夠清淅,具體個案是否可適用訪問買賣易形成爭議。就訪問買賣之定義:「指企業經營者未經邀約而在消費者之住居所或其他場所從事銷售」而言,其簡短之文字並無法清楚勾勒那些情形符合訪問買賣。實務上常見業者主張其到宅銷售係先以電話聯繫,經過消費者事先同意,不屬「未經邀約」之情形,另有主張消費者成立契約係在展覽會場或業者之營業場所,故不屬訪問買賣。究竟何種行銷方式符合消費者保護法所定義之「訪問買賣」?在法律定義曖昧不明之情況下,主管機關於函釋中所表示之見解及司法判決實務所承認之類型,即顯重要,故除了學說之外,本論文將實務見解納為主要觀察對象,並嘗試將觸角伸展至外國法規範,尋求解答。其次,在訪問買賣之適用主體上,金融商品結合訪問買賣之行銷方式為實務所常見,而多層次傳銷參加人亦有購買傳銷商品自用之情形,是否可適用消費者保護法訪問買賣之規定?學說及實務見解存有極大之爭議,本論文就此爭點加以整理並提出解釋意見;在適用之客體上,外國法對於訪問買賣多有除外適用之標的,我國法並未有排除之規定,全國工業總會對此曾提出修正建議,是否應適當調整無條件解除權之適用客體,本論文嘗試從客觀之角度加以分析。   第四章「告知義務及解除權規範之檢討」:為保護消費者於訪問買賣過程中處於弱勢之地位,要求業者應盡買賣條件等資訊提供義務及賦予消費者猶豫期間以重新考量,為比較法上所常見,惟我國之規範內容與外國法相較,除了告知內容顯得不夠充分外,亦欠缺違反告知義務之法律效果,造成許多業者未遵守告知義務,而消費者亦不瞭解自己權利所衍生之糾紛;另外,有關契約解除後,雙方當事人如何回復原狀,亦屬實務上常見之爭議,依現行法制,雖可適用民法第259條等相關規定加以補充,惟若能針對訪問買賣之特性,考量作特別之規範,應較能定分止爭。   第五章「訪問買賣常見消費糾紛類型及實務發展」:經歸納司法院網站所公布最近10年(2000年至2009年)與訪問買賣相關之裁判,發現其契約標的以涉及教材及各類學習課程最多,其次為度假村會員權。此外,訪問買賣銷售人員於行銷時,經常對於資金不足之消費者宣稱可分期付款,惟實際上卻讓不知情之消費者簽下金融機構貸款申請書,一旦發生業者停業、倒閉之情形,消費者不但無法繼續受領商品或服務,反而成為金融機構訴追貸款之對象,形成大量「假分期 真貸款」之爭訟案件。本章針對上述三種消費糾紛類型,探討如何解決類似爭議。   第六章「法制上之建議-代結論」:現行法有關訪問買賣之規範難以符合時代之需求,非但學說存有爭議,主管機關之見解亦常瞹眛不明。實務判決依個案事實,或有引用外國立法例作為法理,依誠信原則調整企業經營者與當事人間之法律關係,然檢討現行法規範,適當地修正或增訂,為釜底抽薪之道。本章綜整前面各章節之議題,就未來修法可思考之方向提出建議。 / The disputes over” door- to- door sales” are increasing year after year. However, the related dissertations are rare. This thesis is trying to generalize theories and rules in order to review current laws and bring up some suggestions. The first chapter “preface” states about the motive and objective of this thesis which is aiming to find the dispute types. Meanwhile, in compliance with the article order of Consumer Protection Act, from definition, application, information notification to rescission, review if current laws could prevent or resolve disputes. Furthermore, observe foreign legislation which is worth imitating. The second chapter ”the statute of door- to- door sales” which is introducing related national statutes and local ordinances; meanwhile, introducing German and Japanese codes, etc. The third chapter “review on definition and application of door- to- door sales”: Since the legal definition “door- to- door sales means a sale completed through trader’s solicitation at the consumer's premises or other locations without any invitation” is not specific enough, there are lots of controversial issues such as- (a) If a consumer shall be considered to have made an express request for a visit by the trader by reason only that the consumer consented to the visit by the trader after an initial contact at which the trader indicates expressly or by implication that the trader is willing to visit the consumer? (b) If a consumer agreement that is concluded at the trader’s place of business or the trade fair could be considered “door- to- door sales”? In addition to discussing above-mentioned issues, who and what subjects are applicable to “door- to- door sales” articles in CPA is a question, too. If an investor or a participant in multi-level sales may apply to them? If the supply of goods which, by reason of their nature, are liable to deteriorate or expire rapidly, or the supply of audio or video recordings or computer software which were unsealed by the consumer shall render the consumer the right of withdrawal? This thesis is trying to analyze foregoing issues objectively. The fourth chapter” review on obligation of providing information and withdrawal of contract”: The consumer is often unprepared in contracts made at the doorstep; therefore it is necessary to provide the consumer a right of cancellation over a period of days and adequate information to enable him to understand the contract. However, the CPA is too simple to protect consumers when comparing with foreign laws. In case we could aim at the characteristics of “door- to- door sales” to regulate individually, the disputes would decrease. The fifth chapter” familiar disputes and legal opinion development”:To sum up the cases filed during last ten years, the most related contract subjects are learning materials including encyclopedias, language books or on-line lessons, etc.;The second is time-sharing membership which is usually touted by taking advantage of human vulnerability;Besides, “linked credit agreement” is also regularly seen. This chapter would make a study of how to resolve the similar problems. The sixth chapter “legal suggestions-instead of conclusion”:Domestic “door- to- door sales” statutes are not able to meet time steps. Not only is there discrepancy between theories, but the opinion of the competent authority is not clear. Some court cases cited foreign laws as jurisprudence to revise the right or obligation between the trader and consumer; Nevertheless, if the competent authority could overhaul the current statutes, the problem-solving methods may be found and established.

台灣期貨市場買賣價差估計值與實際交易成本之研究 / Are spread estimators consistent with transaction cost of Taiwan Futures Exchange?

鄧君祈, Chun Chi,Teng Unknown Date (has links)
This paper focuses on if common effective spread estimators are appropriate for the proxy of Taiwan Futures Exchange. I use public available time and sales data, apply three methods, Roll’s (1984), Thompson and Waller’s (1988), and Smith and Whaley’s (1994) to assess effective spread, and then, compare them with the measured transaction costs proposed by Demsetz (1968). My results indicate that the latter two estimators not only are highly correlated with true transaction costs, but also provide good estimates, while Roll’s estimator appears to be inappropriate applied.

社會網路、買賣、與中介 / The Buyer-Seller-Intermediary Network

許修懷 Unknown Date (has links)
在網路架構下的 first-price 買賣,加入了中介,這裡建構買家二階段的決策,並且探討買家的 連結數、 valuation 、連結成本、 bid 之間的關係。在本文中,中介對想要向中介連結的買家收取費用,接著找出最適的費用以及與其他變數之間的關係,接著在一些額外的假設下找出其配對方法。最後在不同買家 valuation 分配下發現變數間的關係是一致的。 / In buyer-seller network, on empirical premise, each buyer and seller must have a relationship, that is "link," to exchange a good. Each buyer should choose whether to link or not and choose how many links he or she should have. In this paper, we introduce an intermediary in the buyer-seller network. Buyers can construct links by themselves, or they can exchange through an intermediary. On the other hand, the intermediary also charges an entrance fee for its service. We then discuss the intermediaries' behavior and define the allocation rule. We find the intermediary allocation rule achieves maximal profit for the intermediary but this rule cannot reach the maximal total surplus. We also characterize the relationship between link cost, buyers' valuation, the optimal number of links, and the payoff of the buyer and intermediary.
