Agricultural supply response and poverty in Mozambique

What factors effect farmers' marketing decisions in Mozambique?

This paper identifies the key causal factors behind farmers’ marketing decisions in Mozambique. A two-step decision making process is modelled. Farmers decide, first, whether or not to participate in the market and, second, how much to market. The model is estimated using a Heckman switching regression approach. Marginal effects are calculated for the poor and the non-poor and broken down into a market participation component and a quantity (sales value) component.


  • the key importance of non-price factors such as technology, transport infrastructure, farm environment and area characteristics come out clearly
  • the marginal effects for the poor are not substantially different from those of the non-poor, suggesting that differences in assets and area characteristics are more important than differences in underlying behaviour
  • inducing farmers previously not in the market appears more important for total sales than focussing economic policy on those already in the market
  • to achieve pro-poor rural growth it is therefore essential to address explicitly the conditions of high-risk, low productivity and low capital endowments of poor farmers
