109: Hotelling Games This video shows how to play the Hotelling spatial competition games. Here is the : Excel File.
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: equi-distance.
084: Location Choice V This video disproves AGT’s claim that sellers do not move toward the center.
Location Choice in Mountain
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.
087: Maximum Differentiation III This video confirms the conclusion by AGT that sellers do not move toward the center. But, …
Commuting 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.
Location Choice in Inland
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 so-called kinked demand model is arbitrary.
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.
Monopoly
089: Location Choice VII This video proves that, contrary to traditional wisdom, a monopolist faces a more elastic demand curve.
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.
096: Location Choice XI This video shows that a traditional monopolist may not have exactly half of the market.
Duopoly
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.
108: Hotelling & Cournot V This video works out the quantity reaction functions that cover the whole market.
094: Location Choice IX This video shows how two duopolists take over the whole market, not just half of it.
Rent
068: Rent I This video disproves Ricardo’s rent theory by invoking “monopoly has no supply".
069: Rent II This video proves that it is the Central bank that has to be taxed, not the land owner.
070: Rent III This video proves that land supply in not perfectly inelastic.
071: Urban Density I This video shows Beckmann’s failed attempt to reproduce the population density function.
072: Urban Density II This video disproves Edwin Mills’ urban building density function.
073: Urban Density III This video shows Edwin Mills’ failed attempt to reproduce a housing supply density function.
077: Urban Density VII This video disproves Poterba’s housing supply function.
078: Urban Density VIII This video disproves Poterba’s housing demand function.
074: Urban Density IV The video works out the whole population density gradient function.
075: Urban Density V This video works out the rent gradient function.
076: Urban Density VI This video produces a more realistic urban skyline.
Others
008: The Monstrous Trade Model This video proves that the traditional trade model tries to combine an elephant and a giraff together.
143: Wrong Supply II This video shows how traffic congestion is created.
154: Triple Tax This video proves that pollution tax encourages pollution.
372: Crime V This video further proves that punishment is promoting crimes.
