在这项研究中，我们提出了一个理论来解释为什么收入差距持续存在。我们建立了一个简单的代际重叠经济模型，其中包含三种消费品和两种类型的工人。我们发现，高技能工人在技能密集型工作中具有比较优势，而低技能工人在技能密集度较低的工作中具有比较优势。这种比较优势模式决定了工人的职业选择。职业选择与人力资本积累相结合，扩大了家庭之间的收入差距。与此同时，由于生产率的提高，技能密集型产品的相对价格下降。这一下降阻止了收入差距的扩大。技能偏向的技术变革的影响也进行了研究。
In this study, we propose a theory to explain why income gaps persist. We model a simple overlapping‐generations economy with three consumption goods and two types of workers. We find that high‐skilled workers have comparative advantage in skill‐intensive jobs and low‐skilled workers in less skill‐intensive jobs. This pattern of comparative advantage determines occupational choices by workers. Combined with human capital accumulation, the occupational choices widen income gaps between families. At the same time, the relative price of skill‐intensive goods declines owing to productivity improvement. The decline holds back income gaps from exploding. The implications of skill‐biased technological change are also examined.
