Does the focus on financial versus social performance affect the efficiency of double bottom line firms? The case of microfinance institutions.
Unlike purely profit oriented firms, double bottom line firms care about both financial and social performance. Some firms prioritize profits, while other give higher importance to social and environmental impact. Depending on their preferences, double-bottom line firms will choose different output mixes, inputs and production methods. Nevertheless some of these choices might be suboptimal and create inefficiencies.
In this ECCE Webinar, researcher Matteo Millone discusses how focusing on financial versus social performance affects the efficiency of microfinance institutions. More efficient institutions will be able to lend more and therefore will have larger financial and social impact. We will show whether microfinance institutions that focus on richer more profitable borrowers are indeed more efficient or whether it is possible to efficiently lend to the poor. Our analysis offers a tool for microfinance investors to screen microfinance institutions and maximize the impact of their investment.

MFIs differ strongly given differences in their legal status
There is indeed a non-linear trade off between mission
drift and number of clients served
Targeting richer borrowers reduces efficiency
Lending to the very poor is efficient, but not affordable
(for the clients): MFIs with higher outreach charge higher
interest rates
Lending exclusively to women reduces efficiency

Measuring preferences
MFIs have heterogenous preferences (goals), that need to be taken
into account when assessing performance.
Decompose output into 3 measures:
Yield - Price of the Loans
Average Loan Size - Mission Drift(Depth of Outreach)
Number of Loans - Outreach(Breadth of Outreach)
Value Added of Gross Loan Portfolio (Total Output) =
Yield x Average Loan Size x Number of Loans

Circumvents limitations of rating agencies (CGAP, 2010):
Diversity of products and lack of clarity
Duality between assessment for the MFI and service for the
investor
Emphasis placed by MFIs on professional and interpersonal
relationships with rating agencies may jeopardize neutrality of
agencies
