非线性需求下三种市场二度价格歧视的比较

在一类典型非线性需求函数条件下,就一个垄断厂商、二个寡头厂商和三个寡头厂商3种市场情形在实施二度价格歧视时的总收益、总收益增长率、消费者剩余和获取的消费者剩余率进行了比较分析.结果表明:在这类非线性需求函数条件下实施二度价格歧视,垄断性强的市场总能提高生产者利润,而竞争性强的市场总能提高消费者剩余.

Comparison of Three Kinds of Markets on Second Degree Price Discrimination under Nonlinear Demand Functions

Under the condition of a sort of typical nonlinear demand functions,we analyzed and compared total revenue,growth rate of total revenue,consumer's surplus and rate of consumer's surplus gained under second degree price discrimination in case of three kinds of markets: one monopoly enterprise,two oligarchic enterprises,three oligarchic enterprises.The conclusions show that the markets that have more monopoly can always raise producer's profit while the highly competitive markets can always raise consumer's surplus if second degree price discrimination is enforced under this sort of typical nonlinear demand functions
