这样公司2的产量会,导致价格下降直到成本价格

So if I'm Firm 1, if I produce any more quantity, what's going to happen to the price?

如果我是公司1,我要是再生产,价格会怎么变动呢

I won't bother to write it separately for Firm 2, it's going to be the quantity it sells times the price it gets for that quantity, minus that quantity it sells times the cost it incurs in producing that quantity.

我不用另外写公司2的收益了,收益是销量,乘以对应的价格,减去销量乘以产品,的生产成本

So they're going to P1, will the price of Firm 1, and P2 will be the price of Firm 2.

所以P1代表,公司1的价格,而P2代表公司2的价格

So if P1 is less than P2--so if they're the low price firm-- if Coke is the low price firm, only Coke sells in the market.

如果P1小于P2,公司1的价格较低,如果可口可乐的价格较低,市场上将只销售可口可乐

Best price for Firm 1 to choose given that Firm 2 is choosing P2.

公司2选择P2时,公司1的最佳定价是多少

Well it's going to 1 -P1 if they're the low price firm.

如果公司1的价格较低,它是1-P1

So again, for Firm 1 it's the quantity it sells times the price, This is its revenue, minus the quantity it sells times C, the cost, this is his cost.

再次,公司1的收益是其销量乘以价格,即,收入,减销量乘以C,它的成本

This strategy set--formally, Let's just simplify it here-- let's assume that for each Firm i they can set their price anything bigger than 0 and anything less than 1, just to keep life simple.

至于策略集合,我们把它简化成,假设每个公司i能,将它们的价格设定为,大于0并且小于1,仅仅为了简化处理

If Firm II is charging C, Then a best response for Firm 1 is to set price equal to marginal costs, and if Firm 1 is pricing at marginal cost, then conversely a best response for Firm 2 is to price at marginal cost.

如果公司2选择了C,公司1的最佳对策是,定价在边际成本,如果公司1定价在边际成本,同样的,公司2的最佳对策,也是定价在边际成本
