Productivity in Indonesian agriculture: Impacts of domestic and international research
研究了1970年代中期至2000年代中期印尼农业全要素生产率增长中，国内和国际农业研究的贡献，发现国内公共研究几乎解释了全部增长，边际回报率达27%。
Abstract Total factor productivity growth contributed 38% of Indonesia's agricultural output growth from the mid‐1970s to the mid‐2000s. This study uses time series data analysed with an error correction mechanism to examine the contribution that Indonesian publicly funded agricultural research made to this outcome, allowing for other possible determinants of productivity growth, including international agricultural research, extension, government price policy and weather. The results imply a 27% real annual rate of return from a marginal increase in Indonesian agricultural research expenditure. Indonesia's public agricultural research explains virtually all of its agricultural total factor productivity growth between 1975 and 2006.
