Hyperbolic Discounting and Uniform Savings Floor
AbstractI develop a general equilibrium model populated by agents with varying degrees of hyperbolic discounting who vote for a uniform savings floor. Although partial equilibrium intuition suggests that all individuals will prefer to have some constraint on their consumption/savings decision, I find that even the smallest amount of heterogeneity in preferences leads to very large differences in preferred policies. In fact, policy preferences are extreme: each individual either prefers having no floor imposed on the population or having a floor so high that it eliminates all borrowing and lending. I demonstrate that both endogenously determined prices and dynamically inconsistent preferences are necessary for this result. Finally, I consider how the equilibrium savings floor depends on the average amount of self-control in the population.
