Abstract We study the interplay between the decision of firms to innovate and human capital. Based on a dynamic evolutionary model, we show that in the presence of a high stock of human capital, an advanced economy can remain caught in an “innovation trap”. Following the literature on endogenous growth, R&D investments and human capital are modeled as strategic complements. Skilled workers increase productivity and enjoy a wage premium if they are employed in the R&D sector, while they receive the same wage as unskilled workers if they are employed in the production sector. We model the evolutionary dynamics of the share of innovative firms and human capital to determine the conditions under which an economy converges to a high, low or mixed state of innovation.

创新均衡和陷阱的宏观动力学建模

摘要 我们研究了企业创新决策与人力资本之间的相互作用。基于动态演化模型，我们表明，在人力资本存量较高的情况下，发达经济体可能仍会陷入“创新陷阱”。根据关于内生增长的文献，研发投资和人力资本被建模为战略补充。如果技术工人受雇于研发部门，他们可以提高生产力并享受工资溢价，而如果他们受雇于生产部门，他们将获得与非技术工人相同的工资。我们对创新公司份额和人力资本的演化动态进行建模，以确定经济收敛到创新的高、低或混合状态的条件。
