The impact of prices and macroeconomic policies on agricultural supply: a synthesis of available results
综述了农业价格和宏观经济政策对农业供给影响的研究，特别关注撒哈拉以南非洲，指出对供给反应定量维度的理解仍薄弱。
Abstract This paper reviews the literature dealing with the link of agricultural prices and macroeconomic policies to agricultural supply with particular emphasis on Sub‐Saharan Africa. Although the study echoes the stylized facts on price elasticities underlined in previous literature reviews, the paper points out that our understanding of the quantitative dimensions of agricultural supply response is weak given the importance of this assumed response for growth, poverty alleviation, and the environment. Indeed, issues such as simultaneity of variables, data pooling, omission of variables, and asymmetry in supply responses to price changes have not been adequately addressed in many instances.
