Effect of modern rice varieties and irrigation on household income distribution in Nepalese villages
研究了尼泊尔村庄中高产现代水稻品种的差异化采用对家庭收入分配的影响，发现其并未显著恶化收入不平等，因为该技术提高了土地回报但减少了家庭劳动收入。
ABSTRACT Since high‐yielding modern rice varieties (MVs) are adopted only in favorable production environments, significant regional productivity differentials have emerged in Nepal. This study explores the distributional consequences of such differential MV adoption based on an intensive survey of favorable and unfavorable villages. We found that MV adoption increased returns to land but decreased family labor earnings from rice production, as it facilitated the substitution of hired for family labor. As a result, the differential MV adoption did not significantly worsen the household income distribution according to the results of the counterfactual Gini decomposition analysis.
