- Slides: 42
Oligopoly Theory 7. Spatial Competition in Mixed Oligopoly 今日の講義の目的 (1)混合寡占の文脈でSpatial Competition Model e のメカニズムを再確認する (2)Spatial Competition の文脈で混合寡占の特徴を 再確認する OT: Mixed Oligopoly 1
Outline of the 7 th Lecture 7 -1 Shopping Model in Mixed Duopoly 7 -2 Endogenous Cost Differentials in Mixed Duopoly 7 -3 Local Public Firm and Equilibrium Location 7 -4 Elastic Demand Equilibrium Location in Mixed Duopoly 7 -5 Shipping Model in Mixed Oligopoly 7 -6 Foreign Competition and Differentiation 7 -7 Location Equilibrium in Quasi-Linear City OT: Mixed Oligopoly 2
Shopping Model OT: Mixed Oligopoly 3
Maximal Differentiation in Private Duopoly 企業1の立地 0 OT: Mixed Oligopoly 企業2の立地 1 5
Efficient Differentiation in Mixed Duopoly Cremer et al (1991) 企業1の立地 0 OT: Mixed Oligopoly 1/4 企業2の立地 3/ 4 1 10
Endogenous Cost Differentials between Public and Private Firms Matsumura and Matsushima (2004) 設定は生産費用を内生化する以外Cremer et al (1991) のDuopoly versionと同じ。 Hotelling, Shopping Model, Domestic Private Firm (Firm 2), Public Firm (Firm 1) 企業の費用内生化:企業努力によって費用下がる。 努力にはdisutilityが伴う (1)費用削減努力(2)立地選択(3)価格競争 OT: Mixed Oligopoly 11
Efficient and Equilibrium Differentiation in Mixed Duopoly at the second stage 企業1の立地 企業2の立地 0 1 費用をgivenとするとfirst bestのoutcomeが実現 均衡立地の性質は費用格差のない時と同じ OT: Mixed Oligopoly 15
脱線:Kitahara and Matsumura (unplublished) linear city, mill pricing, elastic demand, constant marginal cost, no cost asymmetry, quadratic transport →inefficient location (too close, 私企業が少し離れるとWelfareが改善) 公企業の立地 0 OT: Mixed Oligopoly 1/4 私企業の立地 3/ 4 1 18
Local Public Firm in Mixed Duopoly Inoue et al (2009) 企業1がLocal Public Firm。企業2は域外私企業。こ れ以外Cremer et al (1991)と同じ設定。 OT: Mixed Oligopoly 19
Local Public Firm 域内 0 OT: Mixed Oligopoly 域外 1 1/2 20
Behavior of Local Public Firm ライバルが実質外国企業~ more aggressiveに。 域外の消費者にはなるべく高く売りたい。でも価格 差別は出来ない。~less aggressive OT: Mixed Oligopoly 21
Behavior of Local Public Firm ライバルが実質外国企業~ more aggressiveに。 域外の消費者にはなるべく高く売りたい。でも価格 差別は出来ない。~less aggressive OT: Mixed Oligopoly 22
Shipping Model in Mixed Oligopoly OT: Mixed Oligopoly 28
Equilibrium Location (Oligopoly) 一般性を失うことなく 企業0の立地を0とする 私企業の集積 OT: Mixed Oligopoly 32
外国企業がいたら? Matsushima and Matsumura (2006) Matsushima and Matsumura (2003)の私企業のうち何 社かが外国企業なら? OT: Mixed Oligopoly 35
Equilibrium Location(外国企業3社) 外国企業間の differentiation OT: Mixed Oligopoly 一般性を失うこと なく企業0の立地 を0とする 38
General Model of Linear and Circular City ここを跨ぐ 時βの費用 0 1/2 β=0ならCircular, 十分に大きければLinear。最初の モデルと本質的には同じ。 OT: Mixed Oligopoly 39
Matsushima and Matsumura (2003) Private Firms β =0 0 9/10 Private Firms 1/10 β=1 1/2 Public Firm OT: Mixed Oligopoly delivered pricing, linear demand, constant marginal cost, no cost asymmetry, linear transport cost, Cournot, 40 domestic private
Results Private Firms β =0 0 9/10 1/10 β≧ 2/5 1/2 Public Firm OT: Mixed Oligopoly Private Firms delivered pricing, linear demand, constant marginal cost, no cost asymmetry, linear transport cost, Cournot 41
