Résumé : This paper unpacks the continuum of social finance institutions (SFIs), ranging from foundations offering pure grants to social banks supplying soft loans. The in-between category includes “quasi-foundations” granting loans requiring partial repayment. In our model, SFIs maximize their social contribution arising from financing successful social projects, under a budget constraint dictated by their funders. We determine the feasibility of each SFI category. Quasi-foundations appear to be efficient and adapted to low market rates. However, reciprocity from SFI borrowers can elicit a so-called “hold-up” effect, whereby the SFI charges a high interest rate to its loyal clients.
