英文文献：Dynamics of Human Capital Accumulation, IPR Policy, and Growth-人力资本积累、知识产权政策和增长的动态
英文文献作者：Bharat Diwakar,Gilad Sorek
英文文献摘要：
We study the effect of IPR (Intellectual Property Rights) policy on growth, in a closed overlapping-generations economy, which undergoes transitional development phase of human capital accumulation. We show that the growth-maximizing policy is stage-dependent: in the early development phase, during which innovation cost is high relative to worker productivity, weak IPR protection can expedite economic growth and may be necessary to escape long run stagnation. Weaker IPR protection erodes monopolistic deadweight loss and, thereby, increases aggregate output and saving. However, it also shifts investment away from R&D activity towards the formation of physical capital. We show that the former (positive) effect is dominant during the early development phase. However, as human capital is further accumulated, and labor productivity correspondingly increases, economic growth is maximized with stronger IPR protection.
摘要在封闭的代际交叠经济中，经历人力资本积累的过渡发展阶段，研究了知识产权政策对经济增长的影响。我们表明，增长最大化政策是阶段性的:在创新成本相对于工人生产力较高的早期发展阶段，知识产权保护薄弱可以加快经济增长，可能是避免长期停滞的必要条件。较弱的知识产权保护侵蚀了垄断的无谓损失，从而提高了总产出和总储蓄。然而，它也将投资从研发活动转向物质资本的形成。我们表明，前一种(积极的)影响在早期发育阶段占主导地位。然而，随着人力资本的进一步积累，劳动生产率相应提高，知识产权保护力度加大，经济增长才能最大化。
