An empirical study of the diffusion of new rice-growing practices and their economic impacts on households : The case of Indonesia

本研究的目的是利用在印度尼西亚收集的数据，确定一套新引进的改良水稻管理实践（称为水稻集约化系统（SRI））的社会经济决定因素及其对各种家庭福利措施的影响。我们严格的影响评估表明，SRI产生了显著的产量收益，但收入收益微不足道。我们还发现，家庭劳动较少的农民以及风险和模糊性厌恶的农民不太可能采用SRI。

The objectives of this research are to identify socio-economic determinants of a set of newly-introduced improved rice management practices, called the System of Rice Intensification (SRI), and its impacts on various household welfare measures, using the data collected in Indonesia. Our rigorous impact assessment shows that SRI generates significant yield gains, but negligible income gains. We also find that farmers who are less endowed with family labor as well as those who are risk- and ambiguity averse are less likely to adopt SRI.
