The sluggish supply response in most developing countries to the apparently favourable agricultural market situation of the past few years can be explained by the limited ability of price incentives to bring about an increase in production and marketed surplus in the presence of binding non-price constraints. This article characterises farm household heterogeneity in access to assets, markets and infrastructure drawing on household survey data from 15 developing countries. We relate this heterogeneity in access to household ability to engage successfully in agricultural output markets and find consistent supporting evidence for the hypothesis that this lack of access is significantly constraining their potential to engage successfully in agriculture.Dans la plupart des pays en de´veloppement, la re´action de l 0 offre a`la situation des marche´s agricoles -depuis quelques anne´es favorable -est lente, et ce en raison de la capacite´limite´e des incitations en termes de prix a`ge´ne´rer une augmentation de la production et des exce´dents commercialise´s, en pre´sence d 0 importantes contraintes non tarifaires. S 0 appuyant sur des donne´es d 0 enqueˆtes sur les me´nages recueillies dans 15 pays en de´veloppement, cet article de´crit l 0 he´te´roge´ne´ite´des me´nages agricoles en matie`re d 0 acce`s aux actifs, marche´s et infrastructures. Nous montrons la relation qui existe entre cette he´te´roge´ne´ite´et la capacite´des me´nages a`s 0 engager avec succe`s sur les marche´s de produits agricoles, et trouvons des preuves solides soutenant l 0 hypothe`se selon laquelle ce manque d 0 acce`s limite fortement leur potentiel a`s 0 engager dans l 0 agriculture de manie`re profitable.
Context: Assets, Markets, Agriculture and Poverty ReductionDuring the recent spikes in world agricultural prices, several observers noted with concern that despite the improved terms of trade and overall incentives framework for farmers, agricultural supply response in developing countries was very limited. That observation raises the question of what is constraining the ability of farmers in these countries to take advantage of apparently favourable market conditions (FAO, 2009). One explanation is to be found in the importance of non-price factors in determining farmers' marketed surplus, r
