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： The economic information is long-lived
with a low mean-reversion parameter.
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.
