- Slides: 33
Oligopoly Theory 5. Endogenous Timing in Mixed Oligopoly 今日の講義の目的 (1)混合寡占の文脈でEndogenous Timing Gameの メカニズムを再確認する (2)Endogenous Timing Gameの文脈で混合寡占の 特徴を再確認する OT: Mixed Oligopoly 1
Outline of Fifth Lecture 5 -1 5 -2 5 -3 5 -4 5 -5 5 -6 Stackelberg Duopoly in Mixed Markets Observable Delay in Mixed Duopoly Observable Delay in Mixed Oligopoly Action Commitment in Mixed Oligopoly Two-Production Period Model in Mixed Duopoly Competition against Foreign Competitors OT: Mixed Oligopoly 2
Sequential Move simultaneous-move (Cournot), exogenous number of firms →公企業の過大生産 sequential move gameなら? 公企業がleaderなら? →私企業の反応まで読み込んでより効率的な生産 パターンが実現 (公企業はCournotの時より生産量を減らす・増やす) OT: Mixed Oligopoly 3
Endogenous Timing in Mixed Oligopolyの文脈でEndogenous Timing Gameを分 析 (1)CournotかStackelbergか(Pure Oligopolyと同じ関心) (2)公企業と私企業のどちらが leaderになるのか? (Mixed Oligopoly特有の問題) OT: Mixed Oligopoly 4
Observable Delay in Mixed Duopoly Revisited Matsumura and Ogawa (unpublished) 線形の需要関数、限界費用一定、公企業の方が 限界費用が高い(結果)公企業がLeaderになる均衡とFollowerになる均 衡が存在(複数均衡)→どっちの均衡がrobust? OT: Mixed Oligopoly 11
Observable Delay in Mixed Duopoly Revisited (1) Private Leadershipがrisk dominant (2) Partial Privatizationを考えたとき、Public Leadershipが均衡になるときには必ずPrivate Leadershipも均衡になるが、逆は真ではない OT: Mixed Oligopoly 12
Degree of Privatization and Equilibrium Outcome Private Leadership Public Leadership 0 θ Cournot OT: Mixed Oligopoly 13
Pareto Risk Dominance, Payoff Dominance 2 1 C D C (3,3) (ー100,ー1) D (ー1,ー100) (1,1) Payoff Dominant →(C, C) Risk Dominant →(D, D) OT: Mixed Oligopoly 14
Action Commitment in Mixed Oligopoly Pure Oligopolyと同じ。 n-1ないしn企業がleaders. OT: Mixed Oligopoly 15
Two-Production Period Model in Mixed Duopoly (Matsumura, 2003) 需要関数一般、限界費用一定、公企業の方が限界 費用が高い(が私企業の独占価格よりは低い) OT: Mixed Oligopoly 16
