Talk:Bilateral monopoly

Bilateral Oligopoly?
There a similar definition? Can add here?

Big hypermarket groups, with local domination, like WalMart, TESCO or Carrefour, are examples of bilateral oligopolies? They have both, "buy and sell big power".

No. Bilateral monopoly is a situation where the buyer and seller in a market both have market power to weild against the other. An example would be School Districts and Teacher Labor Unions. School Districts would be a near monopoly (in absence of private and charter schools) in the labor market for teachers. They face a teacher's union that would also have market power as the sole provider of labor to the school districts.

Wal-Mart is NOT a bilateral monopoly in the labor market. They work hard to keep their work force union free and free of market power. It could be argued that in certain rural areas they may be a monopsony for the labor market. For product markets, it is less clear. If your example of Wal-Mart still has strong market power, they would probably be deemed a near monopoly (If they are a seller) or a monopsony (if they are the sole buyer). More than likely they would face suppliers that do not have monopolistic / monopsonistic power. So, Wal-Mart would not be a good example of bilateral monopoly. — Preceding unsigned comment added by 76.174.204.144 (talk) 03:10, 30 August 2011 (UTC)
