The economists Tyler Cowen and Robert Gordon, on the other hand, argue that the problem is on the supply side. In their view, the years following World War II were an aberration, with industrial countries’ growth helped by post-war reconstruction, rising education levels, higher workforce participation rates (owing to the entry of women), restored global trade, increasing investment, and the diffusion of technologies such as electricity, telephones, and automobiles.
另一方面，经济学家泰勒·柯文（Tyler Cowen）和罗伯特·戈登（Robert Gordon）认为问题出在供给端。在他们看来，二战后的时期是失常期，工业国增长受战后重建、教育水平提高、劳动参与率增加（因为妇女加入了劳动力大军）、全球贸易重启、投资增加以及电、电话和汽车灯技术的普及的推动。
