We exploit a policy change in Sweden to estimate the effect of copayments on the demand for children's and adolescents' usage of medical care. To this end, we use population-wide registry data including detailed characteristics of individuals and their medical visits. We examine whether the...

Reference prices constitute a main determinant of patient health care reimbursement in many countries. We study the effects of a change from an "external" (based on a basket of prices in other countries) to an "internal" (based on comparable domestic products) reference price system. We find...

The common German practice of financing the renovation of municipal streets via contributions from home owners is based on the assumption of special advantages for the home owners. But there are no such special advantages. These assumed advantages are wrongly constructed by the courts, and thus...

Many countries with national health care providers and health insurances regulate the market for pharmaceuticals to steer drug demand and to control expenses. For example, they introduce reference pricing or tiered co-payments to enhance drug substitution and competition. Since 2006, Germany...

In this paper cost sharing problems are considered. We focus on problems on a rooted tree, we call these problems cost-tree problems, and on the induced transferable utility cooperative games, we call these games irrigation games. A formal notion of irrigation games is introduced, and the...

We use data on insurance deductible choices to estimate a structural model of risky choice that incorporates "standard" risk aversion (diminishing marginal utility for wealth) and probability distortions. We find that probability distortions - characterized by substantial overweighting of small...

Using SOEP panel data and difference-in-differences methods, this study is the first to empirically evaluate the effectiveness of four different health care cost containment measures within an integrated framework. The four measures investigated were introduced in Germany in 1997 to reduce moral...

Insurance contracts are often complex and difficult to verify outside the insurance relation. We show that standard one-period insurance policies with an upper limit and a deductible are the optimal incentive-compatible contracts in a competitive market with repeated interaction. Optimal group...

We use data on households' deductible choices in auto and home insurance to estimate a structural model of risky choice that incorporates "standard" risk aversion (concave utility over final wealth), loss aversion, and nonlinear probability weighting. Our estimates indicate that nonlinear...

This paper examines the role of both cost-sharing schemes in health insurance systems and entry regulation for pharmaceutical R&D expenditure, drug prices, aggregate productivity, and income. The analysis suggests that both an increase in the coinsurance rate and stricter price regulations...

In response to increasing health expenditures and a high number of physician visits, the German government introduced a copayment for ambulatory care in 2004 for individuals with statutory health insurance (SHI). Because persons with private insurance were exempt from the copayments, this...
