本人在国外学习,听的不是太懂,求达人帮忙...
几个定义麻烦解释下:
1.economic profit
2.normal profit
3.abnormal profit
希望不要简单的解释字面意思... 字面意思我也知道 = =!~
2. 在perfect competition market
the Long Run Equilibrium 是 price=ATC=MC这个点上(因为没法上图)
老师解释这个eqilibrium 的是 0 profit equilibrium
既然是0利益,那应该没有人会在那个market 做啊...
不知道我阐述的清不清楚.... 希望,各位大大帮忙......
最后跗上两个关于normal profit的definition
normal profit is the best profit that a firm could earn in an alternative occupation.[therefore ti is an opportunity cost]
alternatively:
normal profit is the minimum level of profit neceesary to keep a firm operating in a particular line of business in the long-run.
这两个definition把我搞的很晕很晕....>.<!~~~~~
