还是economic profit的问题 positive, economic, ability, profit, return

Kiakaha

有同学问过了，但我还是不太明白。当时的回答是：
经济利润是总收益减总成本，包括显性成本和隐性成本，隐性成本就包括normal profit

return to entrepreneurial ability就是normal profit

The return to entrepreneurial ability is greater than normal in a firm that makes a positive economic profit.
比起一般有经济利润的公司，return to entrepreneurial ability is greater

The return to entrepreneurial ability is less than normal in a firm that makes a negative economic profit - a firm that incurs an economic loss.
比起一般经济利润为负的公司，return to entrepreneurial ability is less



那么，对于“return to entrepreneurial ability就是normal profit”这句话，我的理解就是二者相等。何来的大与小，怎么理解“The return to entrepreneurial ability is greater than normal ”一说。能解释一下么
