Impact of sucrose contents and cooking time on cowpea prices in Senegal

Abstract

An alternative approach to traditional consumer behaviour and demand theory is characteristics theory, which assumes that a consumer’s utility function is generated by the characteristics, or attributes, that goods and services possess. Instead of a utility being a function of a product, it becomes a function of the attributes provided by these products. In this paper a hedonic pricing model is used to investigate the influence of sucrose level and cooking time on cowpea prices in Senegal.  Cooking time has a significant impact on price only at Tilene market in Dakar, while the sucrose contents tend to provide a premium throughout. Further investigation shows that the local varieties, AW, Matam and Ndiassiw have higher sucrose contents than the other cowpea varieties.
