ICT and Productivity in Developing Countries: New Firm-Level Evidence from Brazil and India
利用巴西和印度制造业企业的新数据集，估计包含信息通信技术（ICT）的生产函数，发现ICT资本与生产率正相关，并探讨制度环境对ICT投资和生产率的影响。
This paper uses a unique new data set on manufacturing firms in Brazil and India to estimate production functions, augmented by information and communications technology (ICT). We find a strong positive association between ICT capital and productivity in both countries that is robust to several different specification tests. The paper also breaks new ground when using the Indian data to investigate the effect of the institutional and policy environment on ICT capital investment and productivity. We find that poorer infrastructure quality and labor market policy are associated with lower levels of ICT adoption, while poorer infrastructure is also associated with lower returns to investment.
