本文通过基础研究和应用研究，提出了内生技术变革的一般均衡模型。基础研究在产生的溢出效应的性质和程度上不同于应用研究。我们提出了一种新的方法，通过经验识别这些溢出效应，并将其嵌入到私营企业和公共研究部门的框架中。在描述均衡后，我们使用法国公司研究支出的微观数据来估计我们的模型。我们的主要发现是，统一的研究补贴会因过度补贴应用研究而加剧经济中的动态错配。面向公共基础研究的政策及其与私营部门的相互作用显著改善了福利。
This article introduces a general equilibrium model of endogenous technical change through basic and applied research. Basic research differs from applied research in the nature and the magnitude of the generated spillovers. We propose a novel way of empirically identifying these spillovers and embed them in a framework with private firms and a public research sector. After characterizing the equilibrium, we estimate our model using micro-level data on research expenditures by French firms. Our key finding is that uniform research subsidies can accentuate the dynamic misallocation in the economy by oversubsidizing applied research. Policies geared towards public basic research and its interaction with the private sector are significantly welfare-improving.
