Time Aggregation in Health Insurance Deductibles

Working Paper: NBER ID: w28430

Authors: Long Hong; Corina Mommaerts

Abstract: Health insurance plans increasingly pay for expenses only beyond a large annual deductible. This paper explores the implications of deductibles that reset over shorter timespans. We develop a model of insurance demand between two actuarially equivalent deductible policies, in which one deductible is larger and resets annually and the other deductible is smaller and resets biannually. Our model incorporates borrowing constraints, moral hazard, mid-year contract switching, and delayable care. Calibrations using claims data show that the liquidity benefits of resetting deductibles can generate welfare gains of 3-10% of premium costs, particularly for individuals with borrowing constraints.
