The effects of a large discrete maize price increase on the distribution of household welfare and poverty in rural Kenya1
研究了肯尼亚农村玉米价格大幅上涨对家庭福利和贫困的影响，发现总体影响不大，但区域差异显著，生产区受益而净购买区受损。
This study estimates the effects of a large discrete maize price increase on the welfare of a sample of rural Kenyan households. The usual first-order welfare approximation formula is extended to a second-order formula that allows for supply and demand responses to the price change. Results show that many rural households are not affected greatly by the price change, and there are about as many gainers as losers. However, these full sample results mask important differences across regions. Welfare gains generally take place in major production areas while losses are in areas where most households are net buyers of maize. Semiparametric methods are used to investigate the relationship between income and the size of the welfare effect, and poverty dominance techniques are applied to study the impacts of the maize price increase on rural poverty.
