The burden of low-quality diets and childhood undernutrition is widespread in rural areas in Sub-Saharan Africa, where households rely mostly on agriculture. Various empirical studies have shown the relative importance of the market, and hence food purchases, compared with farm diversification in raising dietary diversity.

Potato (Solanum tuberosum L.) is known for its efficiency in converting resources into high-quality food, which can aid in poverty reduction. However, the potato yield in Rwanda has been declining, leading to farmer dissatisfaction with trading terms and a reliance on low prices in the value chain.

Understanding rice farmers’ responses to market prices is essential for policy makers to design effective policies to better manage input demand and rice supply. This paper applies duality theory to derive the elasticities of input demand and output supply for Vietnamese rice production using a translog profit function approach.

Willingness-to-pay (WTP) studies for traditional food products are plausibly affected by unobserved decisions and strategic collusion between the experimenter and respondents. Similarly, WTP estimates in developing countries using a one-time survey might be inconsistent, as the acceptance of new products likely varies with exposure to product attributes.
