Acemoglu et al., NBER Working Paper, 2013) 【点评】薛涧坡  中国人民大学财政金融学院副教授 【摘要】We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A key feature is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We find industrial policy subsidizing either the R&D or the continued operation of incumbents reduces growth and welfare. This is because of a strong selection effect: R&D resources (skilled labor) are inefficiently used by low-type incumbent firms. Subsidies to incumbents encourage the survival and expansion of these firms at the expense of potential high-type entrants. We show that optimal policy encourages the exit of low-type firms and supports R&D by high-type incumbents and entry. 【主持】陈彦斌 教授
