问题如下：

The team then discusses what the long-term growth path for U.S. GDP should be in the aftermath of exogenous shocks due to the financial crises that began in 2008. They examine several reports from outside sources and develop a consensus view of 10-year annual growth expectations for the items in Exhibit 1.



Using the data in Exhibit 1 and the simplest approach to analyze aggregate trend growth for U.S. GDP, the most likely estimate for the 10-year annual GDP growth (in %) is:

选项：

A.

3.0

B.3.5

C.

3.6

解释：

Correct answer: A

中文解析：

变化带来的增长:(%)=
潜在劳动力就业增长+1.9
劳动力参与率增长-0.3
劳动生产率增长1.4%
= GDP增长率预测值=3.0

嗨，努力学习的PZer你好：


这个为什么不考虑阿尔法的事

这里有劳动生产率增长1.4%

劳动生产率就包含了技术（同学说的阿尔法)和资本。

因此这里是考虑了阿尔法的，只是隐藏在劳动生产率增长这个数据里。
