Steven Cheung 张五常在《卖橘者说》says vote by money is the best. My intuition is he is wrong. But I didn't know how to argue. A few days ago, I finally have a theory. :)
I read Karl Popper is against social science. certainly i disagree. but the argument is subtle. i remember when i first read Karl Popper quite a few years ago, i agree with him on this. i study game theory these days. in BusinessWeek, there was an editorial on this year's Nobel economics. the article blasts game theory ``not testable''. i agree. but i can make some change. :)
books by 吴思 are the best economics books i was reading so far. it's deep but it lacks mathematization. contemporary game theorists' work are good mathematics. but often bad economics. this is echoed by S Cheung and 杨小凯. it's interesting time for an economist.
i remember Knuth once said the 60s and 70s were golden times for computer scientists. it's like that for economists now.
