你有没有过这样的经历:当电影放到一半时,你发现它很不好看,而此时你的电影票钱已不能收回了。这时你有两个选择:一是忍受着看完,二是退场。两种情况,时间和金钱都已付出,这是一种沉没成本。所谓覆水难收,它们应不再是重点考虑的事。一个理性的经济人,如果继续看完意味着受罪,不如退场做其他事情。 Have you ever had such an experience: When the movie is halfway, you find it very unpleasant, and your movie ticket money can no longer be recovered. At this point you have two options: one is to endure reading, the second is to exit. In both cases, time and money have been paid, which is a sunk cost. The so-called overwhelmed water, they should no longer be the key consideration. A rational economic man, if you continue to read meant to suffer, it is better to do other things than exit.
