摘要
在线性需求函数条件下,就一个垄断厂商、二个寡头厂商、三个寡头厂商3种市场情形,用完全信息静态博弈的方法对实施二度价格歧视时产量和价格的确定进行了研究,并就3种市场情形在实施二度价格歧视时的歧视价、总产量、总收益、总收益增加率、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:实施二度价格歧视时,垄断总能提高生产者利润,而竞争总能提高消费者剩余.
Under the condition of linear demand function, we studied the determination of output and price of products by using the method of complete information static game while second - degree price discrimination is enforced in case of three kinds of markets： one monopoly enterprise, two oligarchic enterprises, three oligarchic enterprises. We also analyzed and compared the discriminating price, total output, 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 these markets. The conclusions show that monopoly can always raise producer＇ s profit while competition can always raise consumer＇s surplus when second degree price discrimination is enforced.
