舍得,不舍不得,小舍小得,大舍大得。这是一句妇孺皆知的名言。在舍与得之间,似乎存在着函数般的投入产出关系。有所得,必有所舍。现实中,这是天经地义的。但是,经济学最基本的原理告诉我们,资源有限,欲望无穷。在舍得之间最优的组合是“不舍大得”。 Reluctant, reluctant to give up, little room too small, big house big. This is a well-known saying of women and children. Between homes and things, there seems to be a functional input-output relationship. Have income, there must be homes. In reality, this is perfectly justified. However, the most basic principle of economics tells us that resources are limited and desire is endless. The best combination between the best and the worst is “big”.
