Proceedings of 5th European Business Research Conference 10 - 11 September 2015, St. Regis Hotel, Rome, Italy, ISBN: 978-1-922069-83-2 Advancing the Base-of-the-Pyramid (BoP) Concept Simon Joncourt Brief statement of Research question or objective or statement of problem: The Base-of-thePyramid (BoP) concept advocates the involvement of private companies in order to improve the lives of the approximately four billion people living on less than 2000 Dollars a year. Despite the prominent role it plays among the market-based perspectives for poverty alleviation, it has not reached maturity as a research field. There is still a need for theoretical and empirical advancement. Period of study, methodology or model used: We update and complement the recent review of the BoP concept by reviewing scientific contributions published between 1999 and 2014. We also integrate complementary research domains such as Corporate Social Responsibility, Inclusive Business, Microfinance, Non-profit Expansion, Social Entrepreneurship, and Subsistence Marketplaces into the BoP concept. We use the problematization method to identify in-house assumptions and field assumptions shared across research domains, and test them through critical empirical and theoretical interrogation. We also develop field assumptions for a broader BoP concept. A brief statement of findings: On the empirical level it became evident, that the academic discussion is still not strongly embedded in research institutions from low-income countries. Case studies are fairly spread among low-income and newly-industrializing countries, with a large cluster from India. Financial and communication services dominate the type of products and services investigated empirically. Most case studies derive from qualitative research with interviews as the main method of data collection. Such data is seldom triangulated between data from the organization and the consumers and/or entrepreneurs. All research domains under review have similar in-house assumptions, which can be aggregated into six general field assumptions: business eco-systems, financial viability, innovativeness, resource constraints, role of the poor and scalability. These assumptions inform a framework for management research in BoP markets. ____________________________________________________________ Simon Joncourt, Swiss Federal Institute of Aquatic Science and Technology, Switzerland.
