購屋者房價預期分析

陳佳甫 Unknown Date (has links)
價格預期是影響市場價格波動的重要因素,但過去房價預期的研究多半以客觀的市場與環境因素取代購屋者實際的預期,缺乏購屋個體實際的預期研究。股價與物價預期相關研究已從個體預期的角度發現價格預期具有高度的異質性,隱含多元豐富的資訊。故本研究希望釐清個體購屋者預期,是否因身分屬性、搜尋行為、動機與認知產生不同的預期?房價預期的差異與股價預期、民生消費品價格預期有何不同與類似之處?在不同的景氣狀況之下預期之異質性是否因此而改變? 由於購屋者預期為類別變數,本研究使用多項羅吉特模型。實證結果顯示,購屋者身分、行為、動機與認知使房價預期產生差異,其中女性購屋者看漲機率較男性高與消費市場預期差異結果相同,加上住宅投資消費目的皆較投資者多,推測購屋者對住宅商品之看法仍偏向消費市場。此外,從在不同景氣階段,房價預期之異質性會因此改變,主因是住宅投資與消費價比例發生變化。當市場投資比例增加時,購屋者房價預期差異較大,反之預期差異較小。

論巴代耶的獻祭觀 / Bataille's Conception of Sacrifice

田家源 Unknown Date (has links)
這篇論文的主要面在於探討巴代耶對於獻祭的闡釋。巴代耶以獻祭的觀點,繼續承接尼采對於「上帝之死」的闡述。再者,巴代耶在黑格爾人學的基礎上展開他對於「人」的批判﹔以及針對涂爾幹的集體決定論和神聖與世俗的二分法重新檢討,對神聖與世俗的二分法發生之前有更為根本的認識論。 巴代耶認為獻祭經驗所帶出的異質性在於:獻祭不包含任何功利性,獻祭是要將獻祭即是要將死亡與生命帶入和諧之境,給予死亡生命的湧現,給予生命瞬間性以及令人感到未知的死亡的昏眩。在此生命與死亡交融為一,但同時死亡又是生命的象徵,指向無限的道路。

Background Internet industry grows rapidly. According the Internet report of Mogan Stanley company, new businesses that are created by or for Internet marketplace will grow very rapidly, at an estimated CAGR of 38% from now until ths year 2000. One of the important factor in the Internet's on-going growth is that there are many original innovations in the Internet. One person or a small company can create high innovative value by their own knowledge through the World Wide Web. Innovation becomes an important ubject i2. Purpose According to the research background ,the research objective of this study are four points: (1) To find the innovation on the World Wide Web and the categorization of innovation on the World Wide Web.(2) To explore the characteristic of knowledge with the innovation on the World Wide Web. (3) To explore the relationship between the characteristic of knowledge and categorization of innovation. (4) To explore the relationship between the characteristic of knowledge and the mechanism of integration knowledge?3. Conceptual FrameworkThe literature on organization knowledge and learning has explored the role of organizations in the acquisition, processing, storage, and application of knowledge(Argyris and Schon 1978,Levitt and March 1988,Ribertwon and Swan and Newell 1996). Demsetz(1991) proposes that efficiency in the acquisition of knowledge requires that individuals specialize in specific areas of knowledge, while the application of knowledge to produce goods and services requires the bringing together of many areas of specialized kGrant's(1996) observations of mechanism of integrating knowledge imply that the difference of knowledge characteristic will influence the method of knowledge management and Lyles and Zander(1992) propose the structure of organization knowledge would play an important role in searching the strategic opportunity. Based on the literature review in the preview paragraph, this study proposes the following framework (shown in figure 1), which is made up of two dimensions: knowledge heterology and knowledge complexity as the variables and in order to discussing the company how to integrate different individual's knowledge and to produce innovation on the World Wide Web. 4. MethodologyThe data were collected through research in both primary and secondary sources. Primary data were then collected about the web site project by contacting directly one of the members of web site team and requesting an interview. Search engine is considered the representative product in the Internet and so six project was picked through the recommendation of search engine to show the operation of successful companies on the World Wide Web5. Conclusion(1) The categorization of innovation in Internet industry included incremental innovation and radical innovation. (2) Organizations are more likely to adopt incremental innovation when the degree of knowledge heterology is low and adopt radical innovation when the degree of knowledge heterology is high. (3) Organization will take different mechanism to integrate knowledge when the characteristic of knowledge with Web innovation is different. 3.1 Organizations take "Rules and Directives, Routines, Sequencing, problem solving, dialogue/meeting, multiskilled individual " as the mechanism of integrating knowledge. These mechanisms can be categorized by four mechanism patterns-Organization mechanism, Team mechanism, Individual mechanism and Communication mechanism. 3.2 Organizations will take Team mechanism, Individual mechanism and Communication mechanism, when the degree of knowledge complexity is high and the degree of knowledge heterology is high. The degree of common language is more complex. 3.3 Organizations will take Organization mechanism and Team mechanism, when the degree of knowledge complexity is low and the degree of knowledge heterology is high. 3.4 Organizations will take Organization mechanism and ndividual mechanism, when the degree of knowledge omplexity is high and the degree of knowledge heterology is low. 3.5 Organizations will take Individual mechanism and Communication mechanism, when the degree of knowledge complexity is low and the degree of knowledge heterology is low. The degree of common language is less complex.

新創企業創業團隊關係研究 / A study of relationship of startup company partners

吳梓川, Wu, Zi Chuan Unknown Date (has links)
隨著全球越來越多人和資源投入到新創企業的活動中,創業活動逐漸成為一個國家發展的助力,不僅對經濟發展和社會成長有幫助,對提升就業力和國家創新能力也至關重要。創業過程中關鍵因素之一的創業團隊成員,也越來越受到世界各地學者的重視和研究。但作為一個新的研究領域,依然有很多的不足。如何讓創業者能準確挑選適合自己的創業團隊并維繫團隊成員之間的關係是創業過程中的核心問題。團隊成員關係直接影響了創業團隊的表現,而創業團隊的表現直接影響新創企業的績效。 本研究對已有研究和文獻進行了梳理,總結和評論,針對創業團隊成員的個人特質,挑選因素,成員間的異質性,團隊組成因素,創業團隊成員關係維持,特殊合夥人關係,股權分配以及退出策略八個層面,開展了探討台灣創業環境下創業者及創業團隊成員關係維繫為主題的研究。研究發現以下幾點對關係維繫是正向作用的:創業前確認彼此的信任關係,創業團隊成員具有優秀的特質,創業前明確職責和權利,團隊成員之間願景一致且能力互補,合理分配股權。未來,在本研究的基礎上,還可繼續探究優秀個人特質之間的關係,創業團隊成員的溝通方式,成員的異質性對彼此關係的影響,以及產業細分后的創業團隊成員關係。希望對創業團隊成員關係的研究,能補充現有創業研究的不足,擴大創業理論的研究範圍,給創業者和投資人更多的指導性建議。 / With more and more startups around the globe, entrepreneurship has become a key to the national development, not only to economic development and social growth, also to improving the employment and national innovation capability. One of the key factors of entrepreneurship is the business partner matching. Partner matching has drawn more and more scholars’ attention and research around the world. But as an emerging research area, there are still some theoretical and practical questions worth investigating. How to make sure that an entrepreneur can accurately select a partner that is suitable for the business and how to maintain the relationship between the partners are the core issues in an entrepreneurial practice. In this study, I conducted a comprehensive analysis of the existing literature related to the relationships of business partners. Drawn lights from the literature, this study discussed 8 key variables such as the individual characteristics of the partners, the selection of the partners, heterogeneity among the partners, the factors of the partnership team, the relationship maintenance of partners, the special partner relationship, the distribution of the shares and the withdrawal strategy of the partners. This research grounds itself on the relationship maintenance between entrepreneurs and partners in Taiwan's entrepreneurial environment. The study found that the following aspects are positive for the maintenance of partner relationships: mutual trust among the partners before the partnership, the constructive characters of partners, the clear sense of liability and rights before the partnership, the accordant of the vision and the complementary ability, and the rational allocation of equity. In the future, we will continue exploring the relationship among individual characters, the communication among partners, the impact of partners’ heterogeneity on partnership, and the partnership after industry segmentation. By studying the partner relationship, this study casts light on supplementing the existing research of entrepreneurship, expanding the scope of research on entrepreneurial theory, and giving more practical guidance to entrepreneurs and investors.

教育報酬、工資不均與異質性人力資本的研究

賴偉文 Unknown Date (has links)
隨著理論與實證方法的發展,人力資本報酬的異質性已被國內外學者所重視,因此,本論文採取將人力資本視為異質性的觀點,首先以分量迴歸模型估計不同工資分配下教育的邊際報酬率,呈現人力資本投資在不同工資水準下的異質性,並進一步探討台灣地區工資不均的成因。實證結果發現,若增加對教育的投資將有助於降低勞動市場的工資不均度,而工作經驗的累積則將會擴大工資的不均度。此外,若增加勞動市場高教育程度與(或)女性工作者的比例,將有助於改善工資的不均度,但若勞動市場上高經驗年數之工作者所占的比例愈高,則對工資不均度將有不利的影響。 而為了避免因選擇橫斷面資料分析時所可能產生的偏誤與不一致,本論文以年群世代的資料進一步描述學校教育品質的時間變化,體現教育的品質與內涵。發現過去較年長世代所接受之教育的效果,乃在於加強個人的能力,深化個人專業能力進而表現在工資水準上。而年輕世代所接受之現代教育的效果,則在於補足個人能力的不足之處,表示在年輕的世代中,教育乃做為培養多元或多樣化能力的途徑,彌補先天能力的異質性,更突顯教育於二十一世紀之人力資本投資的重要性。 另外,本論文並考慮人力資本投資的內生性,以工具變數法呈現特殊群組的異質性教育報酬率,並解決可能產生的內生性偏誤估計。結果發現,以工具變數法所估計教育報酬率,均高於傳統OLS所估計的教育報酬率。且透過不同工具變數的選擇與結合,經由多重判斷標準,可得到對平均教育報酬率較有效的一致性估計。我們發現男性與女性教育報酬率分別為5.97%與14.69%,顯示傳統OLS估計的女性教育報酬率存在嚴重的低估現象。 最後以異質性教育報酬率模型估計個人教育決策的選擇結果所造成之異質性教育報酬率。估計的結果發現,若忽略異質性與選擇偏誤的重要性,將導致估計參數的偏差與不一致。而由邊際處置效果MTE曲線發現,愈有可能進入大學就讀的人,有愈高的教育報酬,顯示勞動市場存在比較利益,而遞減的MTE曲線更進一步指明,樣本在教育選擇過程中存在未觀測到的異質性,也更確切地顯示勞動市場中人力資本的異質性與比較利益原則的存在。

異質性偏好與地方公共財之最適提供水準 / Heterogeneous Preferences and the Optimal Provision of Local Public Goods

王舒齡, Wang, Shu Ling Unknown Date (has links)
本文以Tiebout (1956) 之假說 (Tiebout Hypothesis) 為基礎,在數個轄區之經濟環境下,假設人民具有「異質性偏好」及「完全移動性」,利用模擬 (simulation) 的方式,探討人口以及地方公共財之最適配置狀況,並探討其背後所隱含之經濟意義。 本文之研究發現有以下三點。第一,對於公共財具有異質性偏好、且具有完全移動性時,個人會依據自我選擇機制 (self-selection),選擇使其效用極大化之轄區居住,產生區分 (sorting) 之效果,符合Tiebout所預期。第二,就比較靜態發現,在技術水準越高,或者私有財之偏好越高的情況下,高偏好轄區的人口越多,每人持有消費性公共財數量也越多;而當資本產出彈性增加,則高偏好地區人口越少,且每人持有消費性公共財數量越少。第三,若中央政府徵單一稅 (uniform tax) ,且定額稅與資本稅之稅額相等,則以中央政府的角度觀之,不論何種稅制,均不影響全國地方公共財之總提供水準,故異質性偏好在此未造成任何影響。但若以地方政府的角度觀之,並以「每人持有公共財數量」之角度切入,則異質性偏好不但造成區分效果,更使轄區之資源配置具有脫離對稱均衡的可能。若將社會總福利水準極大化時之定額稅定義為最適稅率,其所對應之每人持有地方公共財,定義為公共財之最適提供水準,以此作為比較基礎,則在課徵資本稅之下,生產要素使用之扭曲性,影響人民之消費行為,進而改變轄區內原來的資源配置,強化轄區間資源配置的差異。在本文以兩個轄區為例,並以消費性公共財為分析重點之模型,發現地方公共財的提供,受到轄區內個人偏好強度差異之影響,出現偏好強度高之轄區公共財提供過多,偏好強度低之轄區公共財提供不足之結果。 關鍵字:Tiebout、異質性偏好、完全流動性、自我選擇機制、區分效果。

適用於異質性無線網路之錯誤可調性TCP / Error-Adaptive TCP for Heterogeneous Wireless Networks

張碩瀚, Chang,Sol-Han Unknown Date (has links)
現今我們所住的世界不再只是一個單純的有線網路,隨著WLAN的無線區域網路的存取點越來越普遍,每個家庭使用有線網路做為後端網路然後使用無線區域網路的存取點作為最後一哩的情況也隨著變的常見了,所以現在的網路世界不再只是一個單純的有線網路而是一個有線跨無線的異質性無線網路了,TCP一個我們所常用的傳輸層的協定當遇到異質性無線網路時已經被證實會對封包遺失的原因有誤判,在無線傳輸時封包遺失的理由包括訊號品質不好以及用戶端之間在無線介質中的競爭,因此我們設計了一個具有跨層考量的EATCP-Assisted模組來幫助傳送端收集媒體存取控制層的資訊並使的傳送端在調整競爭視窗上面更有效率,在EATCP中有兩大部分:第一部份是估算階段,第二階段就是EATCP的擁塞控制機制,藉由EATCP-Assisted模組所收集到的wirelessRTT以及utilization我們可以有效的估算出wiredBW以及wirelessBW,並藉由這兩個參數我們可以準確的將封包遺失的原因從頻道衰減以及用戶端之間的競爭中分別出來,因此一個適當的競爭視窗就可以藉由這些資訊來調整出來。 / Recently, with the growth of WLAN, the world we live today is no longer a pure wired network, it’s a heterogeneous wireless network. The TCP that we commonly used has been proven to have misjudgements of packet loss in heterogeneous wireless networks. We design a cross-layer architecture called EATCP-Assisted module to help the sender collect MAC layer information, and adjust the congestion window more efficiently. In EATCP, there are two important parts: the first is estimation phase; the second is congestion control algorithm. By collecting the wirelessRTT, and utilization we can estimate the wiredBW and wirelessBW. The EATCP will distinguish the causes of packet loss from network congestion, channel fading, or contention between wireless clients. Thus, appropriate congestion window adjustment can be done accordingly. The simulation results show that our EATCP outperforms other versions of TCP.
