First, there is the clear existence of seasonal slack periods in rural areas covering much of the year, combined with varying degrees of underutilized land resources (Ruthenberg 1971; Cleave 1974; Delgado and Ranade 1987). This situation is supported in the chapters in this report on Burkina Faso, Niger, and Zambia. Second, the binding constraints on farm exportables are typically those other than the supplies of land and labor that constrain nontradable foods in much of Africa, allowing food production to expand without necessarily causing the export crop production to contract.

In what follows, total household expenditure and income will be used synonymously. This does not alter the conclusions, provided that savings are a constant share of income across households. Even if this assumption is violated, low average savings ratios in rural Africa suggest that any distortion arising from using total expenditures as a conceptual proxy for income is low. 33 To mitigate potential heteroskedasticity problems, the model is estimated in share form. Dividing (1) by E gives, S i = bi + ai / E + ci log E + ∑ (µ ij Z / E + λ ij Z j ), (4) j where Si = Ei / E is the share of commodity i in total expenditure.

What evidence is there of underused resources in rural Africa? While this question has not been conclusively studied, strong anecdotal evidence suggests the existence of such resources. There are two main arguments. First, there is the clear existence of seasonal slack periods in rural areas covering much of the year, combined with varying degrees of underutilized land resources (Ruthenberg 1971; Cleave 1974; Delgado and Ranade 1987). This situation is supported in the chapters in this report on Burkina Faso, Niger, and Zambia.
