Understanding how health care utilization responds to cost-sharing is of central importance for providing high quality care and limiting the growth of costs. We study whether the framing of cost-sharing incentives has an effect on health care utilization. For this we make use of a policy change in the Netherlands. Until 2007, patients received a refund if they consumed little or no health care; the refund was the lower the more care they had consumed. From 2008 onward, there was a deductible. This means that very similar economic incentives were first framed in terms of smaller gains and later as losses. We find that patients react to incentives much more strongly when they are framed in terms of losses. The effect on yearly spending is 8.6 percent. This suggests that discussions on the optimal design of cost-sharing incentives should also revolve around the question how these are presented to patients., Competing Interests: Declaration of Competing Interest There are no conflicts of interest., (Copyright © 2021 The Author(s).

We examine sources of regional variation in ambulatory care utilization in Germany. We exploit patient migration to examine which share of regional variation in ambulatory care utilization can be attributed to demand factors and to supply factors, respectively. Based on administrative claim-level data we find that regional variation can be overwhelmingly explained by patient characteristics. Our results contrast with previous results for other countries, and they suggest that institutional rules in Germany successfully constrain supply-side variation in ambulatory care use between German regions for most patients. Furthermore, we find that both demographics and other patient characteristics substantially contribute to regional variation and that causes of regional variation vary when comparing different regions within Germany., Competing Interests: Declaration of Competing Interest There are no conflicts of interest., (Copyright © 2019 Elsevier B.V.

We examine the effect of retirement on healthcare utilization in China using longitudinal data. We use a nonparametric fuzzy regression discontinuity design, exploiting the statutory retirement age in urban China as a source of exogenous variation in retirement. In contrast to previous results for developed countries, we find that in China retirement increases healthcare utilization. This increase can be attributed to deteriorating health and in particular to the reduced opportunity cost of time after retirement. For the sample as a whole, income is not a dominating mechanism. People with low education, however, are more likely to forego recommended inpatient care after retirement., (Copyright © 2018 The Authors. Published by Elsevier B.V. All rights reserved.)
