有一个笑话是这样的:一个真正的经济学人是不会俯身去拾起那掉在路旁的50块钱的;因为他坚信,在一个具有运作效率的市场里面,实时可得却并不带有风险的盈利是完全不可能的事,所以这背后一定有着其它什么的问题,只要他一拾起那50块钱,就会招惹麻烦,正当这名经济学人仍为地上的50块钱思前想后之际,路旁有小孩踩着滑板经过,一手就把钞票拿起,疾驰而去了。 One joke is this: a real economist will not lean over to pick up the 50 bucks that fell off the road; for he is convinced that in an operationally efficient market, there is real-time availability and Without risk of profitability is absolutely impossible, so there must be other problems behind this, as long as he picked up the 50 dollars, it will cause trouble, just as the economist is still on the ground 50 Qian Siqian after the occasion, a child on the road after stepping on skateboard, one hand took the banknote picked up, gallop away.
