我们提出了一个简单的人力资本积累模型，它产生库兹涅茨曲线作为均衡结果。在模型中帮助生成库兹涅茨曲线的核心成分是我们在学习技术中称之为短期增长的规模回报。学习技术的规模回报是递增的，但只是在短期内，因为生产要素之一的时间是受禀赋限制的。我们证明了短期规模收益递增是获得库兹涅茨曲线的必要条件，但不是充分条件。
We present a simple model of human capital accumulation which generates the Kuznets curve as an equilibrium outcome. The central ingredient that helps generate the Kuznets curve in the model is what we call short-run increasing returns to scale in the learning technology. The learning technology exhibits increasing returns to scale, but only in the short run, since one of the factors of production, time, is bounded above by the endowment. We show that short-run increasing returns to scale is necessary to obtain the Kuznets curve, but not sufficient.
