title = "The response to dynamic incentives in insurance contracts with a deductible: Evidence from a differences-in-regression-discontinuities design",
abstract = "We develop a new approach to quantify how patients respond to dynamic incentives in health insurance contracts with a deductible. Our approach exploits two sources of variation in a differences-in-regression-discontinuities design: deductible contracts reset at the beginning of the year, and cost-sharing limits change over the years. Using rich claims-level data from a large Dutch health insurer we find that individuals are forward-looking. Changing dynamic incentives by increasing the deductible by €100 leads to a reduction in healthcare spending of around 3% on the first days of the year and 6% at the annual level. We find that the response to dynamic incentives is an important part of the overall effect of cost-sharing schemes on healthcare expenditures—much more so than what the previous literature has suggested.",
