Marketed Surpluses of Agricultural Households in Sierra Leone
利用塞拉利昂农户数据，估计农产品和劳动的市场剩余对价格及非价格变量的弹性，发现低支出家庭与高支出家庭的反应同样显著。
Abstract An agricultural household model is used with household level data from Sierra Leone to estimate elasticities of marketed surplus for several outputs and for labor with respect to price and nonprice variables. Positive own‐price elasticities are found, with magnitudes considerably above own‐price output elasticities. Changes in household characteristics and production technology also affect marketed surpluses but not always in anticipated directions. Elasticities are reported for households when grouped by their total expenditure, not just for the sample mean. The differences are important, showing that low expenditure households respond as much as high expenditure households.
