1. Start 

228: Networking III  This video proves that Counot’s networking theory is self destructive. 
2. Cournot 

103: Cournot Competition IV  This video works out Cournot’s quantity reaction functions. 
100: Cournot Competition I  This video proves that Cournot competition ends up with part of the market wasted. 
101: Cournot Competition II  This video proves that Cournot’s pricing policy is very erratic 
102: Cournot Competition III  This video proves that Cournot used only reduction to fight the price war. 
3. Hotelling 

109: Hotelling Games  This video shows how to play the Hotelling spatial competition games. 
080: Location Choice I  This video works out the first round of Hotelling’s spatial competition game. 
081: Location Choice II  This video works out the second round of Hotelling’s spatial competition game. 
082: Location Choice III  This video works out the equilibrium after interaction of Hotelling’s spatial competition game. 
083: Location Choice IV  This video proves the first theorem of Hotelling’s spatial competition game: equidistance. 
094: Location Choice IX  This video shows how two duopolists take over the whole market, not just half of it. 
108: Hotelling & Cournot V  This video works out the quantity reaction functions that cover the whole market. 
084: Location Choice V  This video disproves AGT’s claim that sellers do not move toward the center. 
4. AntiHotelling 

087: Maximum Differentiation III  This video confirms the conclusion by AGT that sellers do not move toward the center. But, … 
085: Maximum Differentiation I  This video works out the first round of AGT’s spatial competition game with quadratic commuting cost. 
086: Maximum Differentiation II  This video works out the second round, and the equilibrium after interaction, of AGT’s spatial competition game with quadratic commuting cost. 
092: Circular Location II  This video proves that Salop’s model is just Hotelling’s model. 
093: Circular Location III  This video works out a solid circular spatial competition model. 
5. Cost 

088: Location Choice VI  This video disproves the conclusion by both Hotelling and AGT that it pays to make consumers miserable. 
095: Location Choice X  This video proves that commuting cost reduces a monopolist’s profit. 
097: Location & Production Cost I  This video introduces production cost into the Hotelling model. 
098: Location & Production Cost II  This video proves that production cost does not raise Hotelling’s profit. 
6. Oligopoly 

110: Kinked Demand I  This video proves that the kinked demand model has too many optimal points. 
111: Kinked Demand II  This video proves that the monopolist demand curve in the kinked demand model is redundant. 
099: Location & Production Cost III  This video proves that externally imposing a cost curve to the kinked demand model is arbitrary. 
091: Circular Location I  This video proves that the socalled kinked demand model is arbitrary. 
226: Networking I  This video disproves the networking demand curve by Katz and Shapiro. 
7. Price War 

116: G&P Competition I  This video proves that the Green & Porter competition is shortsighted. 
117: G&P Competition II  This video proves that the Green & Porter competition is too naive. 
104: Hotelling & Cournot I  This video proves that, contrary to Cournot’s theory, a competitor will not stay on the opponent’s demand curve. 
105: Hotelling & Cournot II  This video proves that, contrary to Cournot’s theory, competition does not lead to erratic prices. 
106: Hotelling & Cournot III  This video shows that reduction is not the only strategy in fighting the price war. 
107: Hotelling & Cournot IV  This video works out the duopoly price reaction functions. 
113: Kinked Demand IV  This video shows the third possible competition strategy: namely shifting the demand curve. 
8. Competition in Reality 

114: Stackelberg Competition I  This video reduces the Cournot competition to a Stackelberg one. 
115: Stackelberg Competition II  This video combines the Cournot and the Stackelberg competition into a prisoner’s dilemma. 
136: Game #7  This video shows that neither the Maximin nor the Nash method can solve the Prisoner’s dilemma of competition. 
118: Final Competition  This video integrates Cournot, Stackelberg and Hotelling Competition. 
090: Location Choice VIII  This video proves that the Hotelling’s demand curve is not a demand relation of consumers, but a pricing policy line of a firm. 
356: Marginalism IX  This video disproves the existence of monopoly demand.
