[原创]MWG高级微观经济学13：逆向选择、信号传递及甄别

3# 猫爪


公式13.B.3的分段函数中，出现了[0,∞]的形式.....Intuitively it means that when the average of the productivity (firm's belef) equates the wage, any # of workers between zero to infinite can be an equilibium, since the profit is the same, 0 . I don't think there is any maths  tricks here.
