企業購併策略之研究-以賽局理論分析

胡漢之 Unknown Date (has links)
本文透過特定之賽局設計,欲觀察廠商在相互整合之現象與原因。內文中之賽局有以下玩家:上游有一獨佔之中間財供應商,而下游有兩種不同類型共三家之最終財生產廠商,而其中一間下游廠商之技術優於其他兩家,其生產最終財之邊際成本較低。賽局之設計為一動態賽局,上游先決定是否進行垂直整合,下游將會觀察到上游垂直整合之意願,並將水平整合視為對上游釋放之友善信號,接著上游廠商將對水平整合之廠商,進一步進行垂直整合;若下游未因上游之意願而進行水平整合,則上游廠商將隨機選擇一間下游廠商進行垂直整合。 廠商於互動時,我們加入不確定性並加以計算並分析;首先是廠商間整合時存在不確定性,由於下游廠商之技術水準為一不透明資訊,換言之,無論是上游觀察下游,或者下游廠商間,皆不了解對方之技術水準,僅知技術水準佳與較差的下游廠商之比例與數量,因此在廠商整合時將面臨整合綜效與技術衰退之風險性;另外,在模型中,加入一整合失敗之懲罰額,當技術較差之兩間下游廠商相互水平整合時,將面臨整合失敗之風險。 經試算後發現,根據這樣的模型設定,若下游未水平整合,或者水平整合之雙方生產技術相異,將會排擠技術較差之下游廠商進行生產;此外,我們亦發現,若進一步分析均衡結果,我們發現,不同技術類型之下游廠商,水平整合之成功(失敗)率,以及兩間技術較差之下游廠商整合後之懲罰金額,皆將影響下游廠商水平整合之意願,若下游廠商不願意進行水平整合,上游廠商經衡量後,將不對下游釋放垂直整合之意願信號,此時廠商間之結構將維持原狀。 本文欲透過加入不確定性,試圖找出與前人研究之異同處;而透過本文之模型設定,我們發現了與前人相似之結論,亦即存在上下游之廠商結構中,將有可能出現廠商間完全分離(沒有任何水平或垂直整合發生)之現象。 / This thesis tries to find out the interaction between firms, especially when these firms face the decision of merging. We also try to figure out the reason why these firms try to merge than stay separation. Here we design a game with some specific conditions for firms to observe the process they merge and the outcomes. In this dynamic game, we design 2 layers, 3 kinds, total 4 firms to be the players of the game. Upstream firm has to make decision whether to merge the downstream firms. Then downstream firms try to merge horizontally after they receive the signal that they knows that upstream firm’s willingness to vertical merge. Here we have to kinds of downstream firms, the one who has better technology has lower marginal cost, in this thesis we assume the marginal cost to be zero. The game have 3 downstream firms totally, so the other 2 downstream firms have the same technology and have the marginal cost above zero. While the downstream firms merge horizontally, they face the uncertainty of the marginal cost changes and the rise of fixed cost, recognized as the failure of integrations. Then the upstream stick to its promise to vertical merge, it will tend to merge the downstream firm which had horizontal merge previously. The result is far beyond the expectation we had before we run this model. The inferior downstream firms will not join the game, even they won’t produce any when the superior downstream firms is vertically merge by upstream firm, no matter the downstream firms merge each other. More, the probability of success in horizontal merge will affect upstream firm to make the decision of vertical merge. The game has only two equilibriums in the end, one is all firms stay separately, and the other outcome is one inferior downstream firm will rule out from the game, and other firms will be merge to one firm and become the monopoly firm in the entire market.

國際多元經貿體系下之政策協調分析-以動態賽局對金融相互依存性之研究

鄧介偉, DENG, JIE-WEI Unknown Date (has links)
隨著世界經貿交通的日益頻繁,國際社會相互依存程度日益增高,各國間任何政策的 推行,往往會牽一髮而動全耳地波及於其他各國造成彼此經濟利益的衝突。於是在各 國規劃及制定財經政策上就必須考慮到此種多元多層面總體經濟體系的干擾。 本論文之目的即在於考慮到目標衝突下的總體經濟政策計畫之有效性,尤其是在有金 融相互依存性下,運用賽局理論(THEORY OF GAME)以及連結賽局理論和最適控制理 論(OPTIMAL OCNTROL THEORY)的動態賽局理論(DYNAMIC GAME THEORY )結合國際 經濟學理論尋求能建立出國際多元總體經濟的模型以作為下列四種方面的應用: (1)國際多元經貿連結理論之分析。 (2)國際經貿組織及區域組織集團中彼此間策略行為之分析比較。 (3)國際政策協調方法的效果分析比較。 (4)國際多元化總體經濟模型之模擬及評估。 以上分析與前賢之不同在於嘗試建立並模擬出有多重元的國際總體經貿賽局模型。換 言之,即是考慮到一國可加入國際經貿組織及區域組織集團中和另外的國際經貿組織 及區域組織集團進行賽局後,再在國際經貿組織或區域組織集團中彼此間進行賽局。 更進一步的話還可以再考慮到一國自己國內各個不同利益團體彼此間再進行賽局。這 即是所謂的層級式多元賽局(此為三重多元賽局)。此種模型可提供作開放經濟體系 在國際間多元經貿關係的簡單模擬,用於解釋並分析該國在國鄉際多元經濟貿易體系 上適當可行的政策方法和效果評估。進而分析該國受到外國經貿政策波及後的影響程 度以及在追求最大或不損及國家利益上協調國際經貿失衡問題的地位和能力。

台北市連鎖便利商店展店行為的動態分析 / An Entry Analysis of Convenience Stores in Taipei

黃伊平, Hwang, I Pyng Unknown Date (has links)
臺灣的連鎖式便利商店密度居世界之冠,為數眾多的門市使得便利商店與臺灣人 民的生活息息相關,就直覺來說,便利商店門市的數量也影響了廠商設立新門市 的決策。本研究建構了一離散選擇的動態賽局,分析臺北市各個行政區便利商店 門市數量對不同廠商設立新門市的影響。實證結果顯示當競爭對手門市數量剛開 始增加時,門市數量對便利商店的利潤有正向的影響,但是當對手門市數量太多 時,此數量的增加對便利商店的利潤產生負向影響。這結果表示一開始門市之間 的互補效果大於替代效果,但是門市數量太多造成過度競爭,此時門市之間的替 代效果大於互補效果。而同品牌的門市數量對於廠商的總利潤也有類似的影響。 另外,本研究也估計便利商店歷年來在臺北市各行政區展店的機率,其中大安區 和中山區是便利商店廠商最想展店的行政區,相對而言,南港區、大同區和萬華 區則是展店機率較低的行政區。 / The density of convenience stores (CVS) in Taiwan is ranked as number one in the world. The highly concentrated market of convenience stores has dramatically changed the lifestyle of Taiwanese people. The number of existing outlets in a region is also an important factor in regard to the entry decisions of new outlets. In this study, we construct a model of the dynamic discrete game, and examine the influence of the rival outlet number on CVS entry decisions in Taipei, Taiwan. The empirical evidence we find is that the CVS profits first rise and then decline as the own or rival outlet number increases. This result implies that the complement and substitution effects vary with the number of the CVS outlets in a specific region. Furthermore, we estimate the probabilities that the CVS companies will set up additional outlets in any district of Taipei during the data period. The results show that it is most likely for the companies to enter the Da’an and Zhongshan districts, while Nangang, Datong and Wanhua are districts with low entry probabilities.
