Resumen
Descripción
This paper reviews the literature dealing with the link of agricultural prices and macroeconomic policies to agiicultural 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. © 1997 Elsevier Science B.V. All rights reserved.
