Gender board diversity and the cost of bank loans

We examine the relationship between female board representation and the cost of lending, using a dataset of 13,714 loans from 386 banks matched with 2,432 non-financial firms from 1999 to 2013. We find that firms with female directors command lower loan spreads. In addition, female independent directors have a stronger impact on lowering spreads compared to female directors' other attributes. However, as firms build relationships with their lenders this effect becomes less potent. Finally, when we introduce firm-level heterogeneity we document that changes in gender diversity exert a stronger impact on the cost of lending in the case of bank-dependent firms, especially for relationship borrowers.
