伯南克的宏经是这么说的（原文如下）
In Okun's original work,the "Okun's law coefficient" was about 3 rather than 2, so each percentage point of cyclical unemployment was associated with a difference between actual output and full-employment output of 3 percentage points. Current estimates put the Okun's law coefficient closer to 2.
还有 ... described by Okun's law, a rule of thumb 经验法则(靠经验估计), rather than a law. 就是说奥肯定律其实是根据经验估计的，严格地说不能算法则、定律。

好，解释的很详细
