The Greens’ proposals encounter two problems. First, the theory. They argue that the reduced hours worked by some could be redistributed to others in order to lower underemployment. They thus fall prey to the “lump of labour fallacy”, the notion that there is a fixed amount of work to be done which can be shared out in different ways to create fewer or more jobs. In fact, if people worked fewer hours, demand would drop, and so fewer working hours would be on offer.
但是绿党的提议碰到两个问题。第一个是理论方面,有的人提出一些人减少的工作时长将会被重新分配给其他人,以此来降低不充分就业。这些人是深受“劳动力臃肿谬论”这一观点困扰;其含义是,需要完成的工作总量是固定的,不过这可以通过不同的方式增加或减少就业机会。但事实上,如果人们的工作时间变短,那么对劳动力的需求也会减少,所以劳动力提供的总工作时长也会减少。
