Which of the following statement is most likely about NAIRU?
选项：
A. It assumes that all labor is alike.
B. This rates are the same for different country.
C. Under NAIRU condition, the infation rate is stable.
解释：
C is correct.
NAIRU assumes the labor are different, also the rate are different between one country and another.
考点： NAIRU
解析： NAIRU 认为不同国家地区劳动力情况的差异很大，所以A选项错误。
因为劳动力差异巨大，所以不同国家地区的 NAIRU 也各不相同。所以B选项错误。
NAIRU是非加速通胀下的失业率，这种情况下经济本身就是稳态均衡的，所以算得的失业率也是稳定的，所以C选项正确。
这是哪个Reading的知识点？
