Where is the ‘Plus’ in ‘Credit-Plus’? The Case of Chiapas, Mexico

It has become common to try and increase the effectiveness of microfinance programmes by adding supplementary services to the financial product. However, the added value accruing from this ‘credit-plus’ approach has been little analysed. We hypothesise that the extent of added value from credit-plus depends on the ability of the credit supplier to cultivate trust, or social capital, amongst clients. Applying difference-in-difference estimation, we exploit a natural experiment of two ‘credit-plus’ programmes in Mexico. The findings suggest that credit-plus is not universally effective, but that it is at its most effective, especially with low-income groups, where ‘bonding’ (within-group) social capital exists.
