论文主要内容如下：This study identifies overoptimism of farmers as an important cause of factor misallocation and inefficiency in agriculture. Annual deviation of rainfall from the local normal is exogenous, unanticipated, and transitory, but we find that farmers substantially adjust labor and land allocation in response to a lagged positive rainfall shock. By examining the response of more than 10,000 farmers in China over 11 years, we show that a lagged positive rainfall shock significantly reallocates labor from high-income off-farm work to low-income farm work, reallocates farmland from high-productivity farmers to low-productivity farmers, and reduces the average rural income by 8.1 percent. We also found that these effects are primarily driven by the irrational responses of low-productivity farmers and that farms with good irrigation conditions are generally not damaged.

 

黄开兴研究员的主要研究方向为环境经济学、农业经济学、人口与经济增长等，论文主要发表于JAERE、JEEM、Journal of Economic Surveys、Oxford Economic Papers、Journal of Agricultural Economics等20余本期刊，并主持自科面上项目、国家重点研发计划专题等课题。
