Put simply, cyclical unemployment is unemployment associated with business cycles- i.e. recessions and booms.

简单地讲，周期性失业是和经济周期有关的失业，也就是衰退期和繁荣期。

By breaking down the three types of unemployment into cyclical unemployment, frictional unemployment, and structural unemployment, we see that an unemployment rate of 0% is not a positive thing.

在把失业拆分成周期性失业、摩擦性失业和结构性失业之后，我们可以看出来，零失业率并不是一件好事。

Conversely, when an economy's output is lower than the level of potential GDP, resources are utilized at levels lower than normal and cyclical unemployment is positive.

反过来，如果经济体的产出低于潜在GDP，资源的利用效率就会低于正常值，那周期性失业率就会为正。
