On the Joint Decisions of R&D and Technology Adoption
构建了一个决策理论模型，分析企业同时决定研发和技术采纳时的相互影响，发现研发成本上升会抑制研发但可能促进技术采纳，而技术采纳成本或利率上升则同时抑制两者。
This paper attempts to bridge the gap between R&D models that do not consider technology adoption decisions and technology adoption models that do not consider R&D decisions. It develops and analyzes a decision-theoretic model on the joint decisions of R&D and technology adoption of a firm. Two interesting comparative statics results are obtained. First, an increase in the cost of R&D reduces the incentive for a firm to do R&D. Secondly, an increase in the cost of technology adoption or an increase in the market interest rate reduces the incentive for a firm to adopt new technology and also reduces the incentive for a firm to do R&D. Under certain conditions, an increase in the cost of R&D increases the incentive for a firm to adopt new technology.
