A public finance analysis of multiple reserve requirements

Abstract

This paper analyzes multiple reserve requirements of the type that have been imposed by a number of developing countries. We show that previous theoretical work on this topic has not succeeded in providing a social welfare rationale for the existence of multiple reserve requirements: in the basic reserve requirements model, any allocation that can be supported by a multiple-reserves regime can also be supported by a single-bond reserve requirement. We go on to present extended versions of the model in which it is possible for a multiple-reserves regime to improve social welfare relative to any single-reserve (currency or bond) and/or deposit-tax regime. We demonstrate the empirical plausibility of our approach by providing a case study of Mexico, a country with extensive historical experience with multiple reserve requirementsDeveloping countries ; Finance, Public
