文章在一个引入租金要素和异质性代理人的一般化动态均衡模型下研究了财富分配的长期演化问题。资本边际产出的分配对于长期财富分配演化结果具有关键意义。在忽略资本差异性影响的条件下,租金的平均分配将带来长期演化下财富分配的平均化;在考虑资本差异性影响的情况下,生产函数的参数特征对租金的正义性分配具有关键作用;在忽略租金差异性影响的情况下,资本的平均分配对长期演化下财富分配的平均化具有决定性作用。文章最后结合现实经济讨论了模型的假设和结果,提出新古典主义生产函数与现实经济情况不符,应该使资本相对稀缺方得到较多租金来推动长期分配结果的平均化。
The paper studies the long-term evolution of wealth distribution under a generalized dynamic equilibrium model that introduces rent elements and heterogeneous agents. The distribution of the marginal product of capital is crucial for the evolution of long-term wealth distribution. Under the condition of ignoring the influence of capital difference, the average distribution of rent will bring about the averaging of wealth distribution under long-term evolution. Considering the impact of capital difference, the parametric features of production function play a key role in the distribution of rent justice ; Neglecting the effect of rent variability, the average distribution of capital is decisive for averaging the distribution of wealth over time. At the end of the paper, the assumptions and results of the model are discussed in combination with the real economy. It is suggested that the neoclassical production function does not match with the real economy, and more rent should be given to the relative scarcity of capital to promote the long-term distribution averaging.
