Abstract
We compare and contrast business networks at the Base of the Pyramid (BOP) and at the Top of the Pyramid (TOP), and analyze their implications for multinational enterprises (MNEs). We first identify the specificities of BOP environments in terms of competitive environment and institutions. Building on this analysis, we develop a series of propositions regarding the impact of these specificities on the structural characteristics of BOP networks, their boundaries, the characteristics of their ties, the diversity of their partners, and their evolution over time, as compared to TOP networks. Our analysis suggests that major differences exist between both types of networks along all dimensions and that these differences have important implications for MNEs active in BOP environments.
