Technological Innovation, Demand Saturation and the Labour Market Puzzle under the Continuous-time Markov Process

在本研究中，我们通过使用多部门模型来分析收入分配和就业的演变，其中新产品的出现遵循称为Yule过程的随机过程。此外，我们假设需求饱和的速度随着产品的出现而变得更快。结果表明，快速的需求饱和加速了就业的增长，但减缓了实际工资率的增长。我们表明，快速的需求饱和加速了利润份额的增长，至少在早期是这样。本文还对我们所使用的多部门模型的理论问题进行了探讨。

In this study, we analyse the evolution of income distribution and employment by using the multisectoral model in which the emergence of new products follows the stochastic process termed the Yule process. Moreover, we assume that the speed of demand saturation becomes faster as the products emerge later. As a consequence, we show that the rapid demand saturation accelerates the growth of employment but decelerates that of real wage rate. And we show that the rapid demand saturation accelerates the growth of profit share at least at the early period. The theoretical subjects concerning the muilsectoral model that we use are also investigated.
