Cortez comments: “The big disadvantage to the leading indicator approach is that it has not historically worked because relationships between inputs are not static. One major advantage to the econometric approach is quantitative estimates of the effects on the economy of changes in exogenous variables.”
Q. Cortez’s comment with regard to the two different approaches to economic analysis is most likely:
- incorrect because of the statement regarding leading indicators.
- incorrect because of the statement regarding econometrics.
- correct.
这是一道官网题目 ，我的问题是leading indicator has not historically worked 这句话对吗
我笔记是has not consistently worked，as relationships between inputs are not static，如果一直不管用也就没有所谓的leading indicator了吧，我觉得只能说不是一直有效
另外笔记还有一句leading indicator优点：a literature exist on the effective use of various third party indicators，这句话怎么翻译？
