Seems like Ph.D. economics programs like to get students from Mathematics,
Physics most. That is why you can see a lot of economists from other majors.
You know how they do economic research? I once saw one, Ping Chen, now in
Center of Chinese Economic Research(CCER), gave a seminar in Academy of
Social Sciences, using Browny movement(?, not sure how to say it in English)
to explain U.S. stock market, crazy! I just don't know if that works. The
latest seminar he gave in Peking univ. is called La

I did not say anything like economics has a lot in same with mathematics.
What I said is Ph.D. economics programs in U.S. enroll a lot of students
from other departments, especially mathematics. And you know why. That's
all.
Another physicist & economist? If yes, who?
Cool! I am not familiar with this field, so I can not go further. To be
accurate,
I should say what he did(using Brownian motion to explain U.S.stock market)
SOUNDED crazy to me. After I came to U.S., I see similar methods every n

90年代初的时候用数理模型炒股很是热了一阵,华尔街招了很多数理专业的
Ph.D,我们学校很多中国人毕业后就去干了这个,我们这的教授有时还说起,
中国学生对科学的热爱远比不上美国学生,读了Ph.D居然去的是华尔街,
大摇其头不止,hehe.
我最赞成的就是刘说的交流方面,华人确实应该全方位地努力进入美国社会
的各个阶层,包括从政.我个人认为于人于己最差的一招就是一直拿绿卡
不入籍.我实在无法理解这种选择背后的逻辑.华人,特别是大陆来的留学生,
要不就学成回国,要不就入籍,越快越好.

shiya, that's the way economists work;
that's long time ago; like Liu said: at his time; life is much easier; more
opportunities. and he is comparetively better than other chinese i bet.

of course; after all economics is analyzing society and
human behavior; i believe math and logic are closer to
economics than physics is;【在 Leo (最受不了是骟情) 的大作中提到: 】
sure it is normal; probably s/he does not know the literature about pricing
theory, which is forgivable even if s/he is an economics student; not
everyone
is focusing on financial analyzing.

well, perhaps LONG TERM CAPITAL has set up an example
for everybody: MATH (OR PHYSICS) IS NOT THE SECRET OF SUCCESS.
what about the PHDs in physics and math they hire;
merton and sharlods(not sure of the spelling) r "ox" enough le ba;
even Samuelson said:"for others the question of winning
NOBEL prize is a question of if or not; for merton t is
a question of sooner or later"(not exactly like this, but the idea
is here) they lost their faces in front of the all world le ba;
in stock market, i be
