Distorted Technology Adoption
研究了企业层面的制度扭曲如何影响跨国技术采用差异，发现规模相关的扭曲阻碍高生产率企业采用新技术，解释了约一半的跨国采用滞后差异，且扭曲导致的生产率损失是静态错配的两倍以上。
Abstract To what extent do firm-level institutional distortions drive cross-country technology differences? I develop a quantitative model of technology adoption in which heterogeneous firms adopt technology depending on their underlying productivity and institutional environment. The institutional environment is represented by size-dependent firm-level wedges on revenues that distort firm decisions. The model is calibrated to match the US firm employment distribution and the average adoption length of new technologies. In less developed countries, measured size-dependent distortions hinder highly productive firms, delaying the adoption of new technologies as these firms are (otherwise) early adopters. Measured differences in size-dependent distortions explain around half of the observed cross-country variation in adoption lags. Additionally, distorted technology adoption over doubles the aggregate productivity loss compared to static misallocation alone.
