Book excerpt: To predict the effect of economic policies on household welfare, one should first understand which characteristics of households and of the localities in which they live, enable them to raise their welfare levels. This paper outlines a simple procedure for investigating the determinants of household welfare and demonstrates its use with recent data from Cote d'Ivoire. Despite the relative simplicity, much information is obtained from its use on cross-sectional survey data. Results specific to Cote d'Ivoire include : high (low) returns to education in urban (rural) areas; high benefits from cocoa land relative to coffee land; a significant impact on economic welfare from the availability of medical services, and no apparent benefits from agricultural extension services.
