好的市场设计能让个人激励与社会效率保持一致。

The secret of living is to own a convertible and a lake...If the sun is shining, you can rid around in your convertible and be happy...If it starts to rain, it won't spoil your day because you can just say, 'Oh, well, the rain will fill up my lake!'"”

Only if we understand, can we care. Only if we care, will we help. Only if we help, shall all be saved.

我不认为你可以准备得太多。
