Effectiveness and Efficacy of R&D Subsidies: Estimating Treatment Effects with One-sided Noncompliance

 計量経済学の厳密なアプローチに基づいた因果関係の識別についての、最新の議論の一つであり、エビデンスベースの政策立案において重要な知見を提供するものであった。同時に、このような豊富かつ貴重なデータセットを作り上げた取り組みの有益性を物語るものであった。(東京大学工学系研究科 吉岡 徹)

In evaluating the effectiveness of R&D subsidies, the literature so far has completely neglected the possibility of misappropriation of public funds. This paper contributes to the literature by evaluating the causal effect of R&D subsidies on R&D expenditures when monitoring is weak and misappropriation takes place due to moral hazard behavior. Our analysis is based on Chinese firm-level data for the period 2001-2011. Misappropriation is a major concern as we calculate that 42% of grantees misused R&D subsidies, corresponding to 53% of the total amount of R&D subsidies. In a setting with one-sided noncompliance to funding contract rules, we differentiate between the intention-to-treat (ITT) effect and the complier average causal effect (CACE). The ITT shows how effective the R&D policy was in practice when misappropriation exists. The CACE, in contrast, depicts how effective the policy could have been without misappropriation and thus is a measure for the efficacy of the R&D subsidy policy. Combining entropy balancing and IV methods to estimate both ITT and CACE, the ITT results show mild partial crowding out of R&D expenditures. Most strikingly, however, the CACE turns out to be more than twice as large as the ITT and confirms additionality of R&D subsidies. Thus, misappropriation of R&D subsidies considerably undermines the efficacy of Chinese R&D programs.
