Price and control elasticities of demand for savings

A Philippine bank tested sensitivity to interest rates and account ownership requirements in 10,000 randomized door-to-door solicitations for a commitment savings account. Take-up is substantial (23%), but price elasticity of saving in this account is not significantly different from zero in either the full sample or sub-groups of plausibly marginal savers. The upper bound is less than 0.5 in the full sample, and exceeds 1.0 in only 1 of 22 sub-groups. Nor do we find sensitivity to ownership requirements.
