ANDE and the International Growth Centre at the London School of Economics released the report A Research Agenda for the SGB Sector in November 2018. Hundreds, if not thousands, of programs exist to help drive business growth in emerging markets. But what does the evidence actually tell us about whether these programs help businesses grow? And what can practitioners learn from this evidence to design more effective interventions? This knowledge synthesis summarizes the current evidence, identifies gaps in the academic research, and proposes a practitioner-oriented research agenda for the sector.
