analyst forum 都上不去了。又记起几道北美题。

 

quants: 1) why is it not a good time series model? 选了autocorrelation 还有一题和time series 相关的,我记得和ARCH 有关,但不记得题干了。

 

econ:1) regulation on emission: social regulation for market failure, econ regulation for lemon problem, econ regulation for assymetric information? I picked B, but now I think it should be A

2) dealer 1 has bigger spread than dealer 2. I picked expectation on FX volatility.

3) how much foreign currency for 1 dollar using dealer 2?

4) if future rate is higher than expected future rate (I calculated it based on int rate), borrow or lend $?

我选的“符合要求”,因为第一他不是分析师而是money manager;第二那些客户都是风险帐户,不存在suitability的问题

我也选的“符合要求”,没看出和公司建议反向操作不一样来。唉,估计错了。
