電子化服務傳遞之協同式定價模式研究 / iPrice: A Collaborative Pricing Model for e-Service Bundle Delivery

張瑋倫, Chang,Wei-Lun Unknown Date (has links)
Information goods pricing is an essential and emerging topic in the era of information economy. Myriad researchers have devoted considerable attention to developing and testing methods of information goods pricing. Nevertheless, in addition; there are still certain shortcomings as the challenges to be overcome. This study encompasses several unexplored concepts that have attracted research attention in other disciplines lately, such as collaborative prototyping, prospect theory, ERG theory, and maintenance from design, economic, psychological, and software engineering respectively. This study proposes a novel conceptual framework for information goods pricing and investigates the impact of three advantages: (1) provides collaborative process that could generate several prototypes via trial and error in pricing process, (2) deliberates the belief of consumer and producer by maximizing utility and profit, and (3) offers an appropriate service bundle by interacting with consumer and discovering the actual needs. Due to the unique cost structure and product characteristics of information goods, conventional pricing strategies are unfeasible, and a differential pricing strategy is crucial. Nevertheless, few models exist for pricing information goods in the e-service industry. This study proposes a novel collaborative pricing model in which customers are active participants in determining product prices and adopt prices and services that meet their changing needs. This study also shows that the collaborative pricing model generates an optimal bundle price at equilibrium with optimal profit and utility. Theoretical proofs and practical implications justify this pricing model, which is essential for future information goods pricing in information economy. Moreover, we apply iCare e-service delivery as an exemplar and scenario for our system. The objective of iCare is to provide quality e-services to the elderly people anywhere and anytime. The new pricing method will go beyond the current iCare e-service delivery process which furnishes personalized and collaborative bundles. iPrice system for pricing information goods fills the gap among previous literatures which only considers consumers or providers. Different from existing works, iPrice system is novel in integrating distinctively important concepts yielding more benefits to consumers and profits to more providers. Thus, iPrice also guides and provides a roadmap for information goods pricing for future research. / Information goods pricing is an essential and emerging topic in the era of information economy.

利差交易新風險因子:無風險實質利率 / Risk Free Real Rate as a New Risk Factor to Carry Trades

林品傑 Unknown Date (has links)
未拋補利率平價說的不成立,衍伸出平均報酬大於零的利差交易(carry trades)。 過去基於風險解釋的文獻,提出各種風險因子欲歸因此套利策略的不尋常超額報酬,實為承擔不同風險的額外補償,亦即風險溢酬(risk premium)。 不同的風險因子可略分為兩派:一為有經濟理論根據,卻在實證上未獲支持的「消費成長因子」;二為在實證上具顯著解釋力的「外匯相關因子」, 卻無理論依據而難以賦予利差交易報酬經濟意義。 本文主張以無風險實質利率作為風險因子。此想法源於隨機貼現因子(stochastic discount factor)之定義式以及現實環境中的觀察。 我們的實證發現,實質化的美國公債利率對於利差交易的報酬有顯著的定價能力。 本文更進一步驗證,本因子甚至比起文獻上的外匯波動度因子,更具顯著的定價能力。另外,本因子亦能解釋動能利差交易之報酬,此為高減低因子所不能定價的報酬。

效用無差異價格於不完全市場下之應用 / Utility indifference pricing in incomplete markets

胡介國, Hu,Chieh Kuo Unknown Date (has links)
在不完全市場下,衍生性金融商品可利用上套利和下套利價格來訂出價格區間。我們運用效用無差異定價於此篇論文中,此定價方式為尋找一個初始交易價,會使在起始時交易商品和無交易商品於商品到期日之最大期望效用相等。利用主要的對偶結果,我們證明在指數效用函數下,效用無差異定價區間會比上套利和下套利定價區間小。 / In incomplete markets, prices of a contingent claim can be obtained between the upper and lower hedging prices. In this thesis, we will use utility indifference pricing to nd an initial payment for which the maximal expected utility of trading the claim is indierent to the maximal expected utility of no trading. From the central duality result, we show that the gap between the seller's and the buyer's utility indierence prices is always smaller than the gap between the upper and lower hedging prices under the exponential utility function.

在HJM模型下使用遠期定價法評價或有求償權 / Pricing Contingent Claims under HJM Model using Forward Pricing Method

張佳沛, Chang,Chia-Pai Unknown Date (has links)
我們使用一個新方法來評價美式或歐式的或有求償權,其受到本地利率和權益價值的影響。我們使用標的資產的遠期價格的樹狀圖,進而對或有求償權作定價。其中我們評價了美式與歐式的股票選擇權,以及利率期貨和利率期貨選擇權。 / We introduce a methodology for pricing American or European style contingent claims, influenced by domestic interest rates, and equity prices. Instead of using trees of short-term interest rate, bond price or forward interest rate, this tree method will use the forward prices of underlying assets to derive implied binomial spot-price tree and in turn price long term American or European options, and interest rate futures and interest rate futures options.

A pricing approach to improve QoS and increase provider revenue in UMTS/WLAN network / 雙網環境下藉由價格機制改善服務品質與廠商收益之研究

呂柏翰, Lu,Bohan Unknown Date (has links)
在未來異質網路的整合環境中,QoS的問題益形重要,而以現今的網路環境而言,最有可能的異質網路整合是UMTS與WLAN。在本計畫中,我們將以UMTS與WLAN的異質網路整合環境作為基礎,提出Pricing-Improved QoS的觀念,結合Non usage-based pricing、Usage-based pricing、Static pricing和Dynamic pricing的優點以及DiffServ (Differentiated Services)劃分服務等級(service level)的機制,實際設計出使用者效用函數(utility function)與網路成本函數(cost function),並以分級訂價方式訂定價格。藉著價格機能,讓使用者表達其對服務等級的需求或期望,並使網路資源適當地分配給各種服務,避免資源浪費或錯置的情形,以符合QoS的需求並提高整體社會福利及增加廠商收益。 / The issue of QoS is getting more and more important in the future integration of heterogeneous networks, and the most feasible integration is UMTS and WLAN as for present network environment. In our research, we would propose the concept of pricing-improved QoS combined with the advantage of usage-based, non usage-based, static, and dynamic pricing schemes and the mechanism of differentiated service classess of DiffServ (Differentiated Services) based on the integration of UMTS and WLAN. We would propose the utility function and cost function in detail, and price by differentiated service classes. By the affection of price, a user could express the service class he actually needs and expects. Network resources would be allocated appropriately to each service class avoiding the inappropriate allocation and wastage. This would meet the requirement of QoS and improve the providers’ revenue and overall social welfare.

女性獨立董事對會計師選擇與審計定價影響之研究 / The impact of female independent directors on auditor choice and audit pricing

黃瑩茲 Unknown Date (has links)
近年來,女權意識逐漸抬頭,女性在商業所扮演的角色也漸受重視,根據《第三期中國婦女社會地位調查主要數據報告》,中國女性的就業率及教育程度已逐年提升,女性在工作上的表現也不亞於男性。由於獨立董事與外部審計同為重要的治理機制,且在中國,獨立董事就有權對會計師事務所的聘任及審計公費的決定程序發表意見,因此,為了解性別多元化對董事會決策之影響,本研究以中國2006年-2011年的A股上市公司為研究對象,來探討女性獨立董事對會計師選擇及審計定價之影響。在控制其他變數之後,本研究發現,當公司有女性獨立董事且女性獨立董事比例越高時,越不傾向選擇國際四大或中國國內十大會計師事務所進行審計;另外,本研究也發現,女性獨立董事比例越高之公司,其審計公費越低。 / Independent director and external audit are both important corporate governance mechanisms. In China, independent directors are authorized to provide suggestions on auditor choice and the decision process of audit fees. Considering gender diversity of the board may affect the monitoring role performed by independent directors and the decision made by independent directors, we conduct a study using a sample of China A-shares over the period 2006 to 2011 to realize the relationship between female independent director and external audit, including auditor choice and audit fees. After controlling other variables, we find that corporations with female independent directors are less likely to choose Big4 and China local 10 as their audit firm than those without female independent directors. Furthermore, there is a significant negative relationship between female independent director ratio and audit fees. This may indicate that female independent directors can partly substitute the governance function of external audit and thus reduce audit fees and the possibility of choosing bigger audit firms.

兩段迴歸結合蒙地卡羅模擬對可轉債定價之研究 / Pricing Convertible Bonds by Piecewise Regression and Monte Carlo Simulation

董恆元, Tung, Heng Yuan Unknown Date (has links)
可轉換公司債兼具了選擇權以及債券的性質,價值又會受到股價之影響,以傳統的方法定價十分不易。由於蒙地卡羅模擬能解決定價問題上狀態變數或許為多維度及路徑相依的問題,Kind 與Wilde 在2004 年提出以蒙地卡羅模擬對可轉債定價,且以最小平方迴歸法估計繼續持有價值,並在僅考慮轉換及還本兩種選擇權及沒有違約風險之下,以數值範例呈現單一迴歸模式無法適當估計繼續持有價值。然而,他們並未進行實證。本研究乃以民國99 年台灣發行的可轉債為研究對象,除考慮發行時的合約條件外,另加上信用評等的考量以將違約機率透過現金流量套入定價過程中,並分別以兩段迴歸及單一迴歸估計繼續持有價值以結合蒙地卡羅模擬,實證結果顯示就可轉債之起始定價的偏差比而言,兩段迴歸得到的結果優於單一迴歸。惟在兩段迴歸之下,超過八成的可轉債其模擬價格依然高於市場價格。實證結果也顯示價性(moneyness)及擔保狀況與定價的偏差有關。 / Convertible bonds (CBs) possess features of both bonds and options, and their prices are affected by the underlying stocks, which make the pricing problem an uneasy task for traditional methods. Since Monte Carlo simulation can handle the problems of path-dependence and multivariate dimensions faced by pricing, Kind and Wilde (2004) suggested to price CBs via least-squares Monte Carlo simulations (LSM), which estimate the continuation values by least squares regression. They also demonstrated that a single regression line could not appropriately estimate the continuation value even only conversion and redemption were allowed and the CB was free of default. So the idea of piecewise regression was recommended to improve the estimation process. However, they didn’t apply piecewise regression to real data. Therefore, piecewise regression together with Monte Carlo simulation were employed to investigate the pricing issue of Taiwan’s CBs. CBs issued on 2010 were selected, besides reviewing the contents of CB’s contracts, default risks based on credit ratings were taken into account to evaluate the discounted cash flows in the pricing procedure. Comparing the estimated model prices of LSM with initial selling prices, the mispricing rates of single regression model and piecewise regression model were obtained for further analysis. Result shows that the modified piecewise regression method performs better in mispricing rate. However, similar to previous findings, 80% of the estimated model prices based on piecewise regressions are still higher than market prices. It also shows that moneyness and guaranteed condition will relate to mispricing rate.

可轉換公司債定價研究

吳佩倫, WU,PEI-LUN Unknown Date (has links)
我國目前的證券市場過份偏重於股票市場,忽略了債券市場,使得市場上彌漫著投機 氧氣,養成社會大眾不勞而獲的心理,為了改正這種氣習,需要加強債券市場的發展 ,使股票市場與債券市場齊頭并進。 而我國一般民眾對債券市場并不熟悉及熱衷,為了發展債券市場及吸引投資人的注意 ,可引進一新工具,那就是可轉換公司債。所謂可轉換公司債為一公司債訂有一轉換 比率,使得可轉換公司債之擁有者可將其債券轉換成該公司的股票。 由於轉換公司債的特殊性質,同時兼顧了債券與股票的雙重特性,使得其成為證券市 場上極具吸引力的一項商品,可抓住投資人的興趣,使得投資人逐步邁進債券市場。 由於可轉換公司債的特殊性質,使得判斷其價格是否合理,較判斷股票及公司債困難 許多。因為其較一般公司債多了一轉換權利而增加了資本利得的機會,也較股票多了 一最低保值額,所以可轉換公司債的訂價方式也就顯得較復雜,而不易判斷其價值。 本文除了介紹可轉換公司債的基本性質之外,還特別著重於可轉換公司債的訂價研究 ,希望藉此研究,可得出一結論對於投資大眾及發行公司都有所助益。

新產品上市活動對競食效果之影響

鄭竹君, Cheng Chu-Chuan Unknown Date (has links)
本篇論文主要探討新產品上市行銷活動中的新舊產品定價相近程度、新產品上市促銷努力程度、與新產品預告時間對競食效果之影響,並瞭解在不同市場競爭強度下,這些變數對競食效果之影響程度有何差異。若確認市場競爭強度對競食效果具有干擾性的影響,則廠商在新產品上市時就可以此為依據,選擇不同的上市行銷活動以達成其策略目標。 本研究以天下雜誌2001年一千大企業調查光碟旗艦版中『製造業』部分為研究對象,用問卷調查方式收集資料,以瞭解在不同市場競爭強度下,新產品上市活動對競食效果之關係。研究結果發現如下: 1.『在高市場競爭強度下,新舊產品間定價相近對競食效果的正向關係越強』在研究中獲得支持,但新舊產品間定價相近與競食效果間存在正向關係則未獲證實。 2.『在高市場競爭強度下,新產品上市預告時間對競食效果的正向關係越強』在研究中獲得支持,但『新產品上市預告時間越早,則競食效果越大』之關係並不顯著。 3.『在高市場競爭強度下,新產品上市促銷努力程度對競食效果的正向關係越弱』在研究中獲得支持,但新產品上市促銷努力程度與競食效果間的正向關係則並不明顯。
