We examine how increased competition among motivated microfinance institutions (MFIs) impacts the poorest borrowers' access to microfinance. We find that competition depends on inequality, technology, and the possibility of double-dipping (borrowing from several sources). Without competition, even a motivated MFI may lend to the not-so-poor in preference to poor borrowers. If double-dipping is feasible, competition may encourage lending to the poor. The presence of double-dipping is critical for MFI competition to have a positive effect. When double-dipping is feasible, MFI coordination may worsen borrower targeting whenever inequality is intermediate. We discuss policy implications dealing with double-dipping, MFI coordination, and competition.
