Thereby we link the multiplicity of equilibria, which emerges in...

The Effect of Bank Competition on the Bank's Incentive to Collateralize

Hainz, Christa - 2007

It has been argued that competing banks make inefficiently frequent use of collateralization in situations where they are better able to evaluate a project's risk than entrepreneurs. We study the bank's choice between screening and collateralization in a model where banks do not have this...
