问题如下：
The Bureau of Labor Statistics has just reported an unexpected short-term increase in high-priced luxury automobiles. What is the most likely anticipated impact on a mean-reverting model of interest rates?
选项：
A. The economic information is long-lived
with a low mean-reversion parameter.
B. The economic information is
short-lived with a low mean-reversion parameter.
C. The economic information is long-lived
with a high mean-reversion parameter.
D. The economic information is
short-lived with a high mean-reversion parameter.
解释：
D is correct. The economic news is most likely short-term in nature. Therefore, the mean reversion parameter is high so the mean reversion adjustment per period will be relatively large.
题目说这个原本价格就很高的产品突然价格又增加了，这并不能说明这个商品回到了均值回归的水平，反而离均值更远了，所以是low mean reversion，因为是low meanreversion所以均值回归花的时间要长，long lived
