Why include the BOP in your international marketing strategy

Purpose The purpose of this paper is to test the premise that brand growth can come from targeting the poorest consumers at the bottom of the economic pyramid (BOP). This study is the first that uses quantitative marketplace data covering BOP consumer purchase records. Design/methodology/approach The study uses newly available panel data from Egypt covering 15 months and 35 categories of frequently bought consumer goods. Brand penetration rates for socio-demographic tiers are established to explore brand purchasing. The metrics are: penetration, the number of buyers a brand has; and loyalty as measured by purchase frequency and share of category requirements. Findings Buyer behaviour patterns for the poorest consumers do not differ much from those in advanced economies; all brand performance metrics vary according to brand penetration - a double jeopardy effect, and the biggest brands are those that target the whole market, including the base. Originality/value This paper extends previous research on brand buying behaviour for the first time to the vast base of poor consumers who make up around half of the world's population. This research shows that strategic approaches that emphasise increasing penetration are most likely to result in brand growth.
