One cornerstone of current attempts to reform the German public health care system by introducing private insurance schemes is the assumption that economic incentives play an important role in individual decision-making about using medical help. This hypothesis is examined for the case of demand...

This paper provides field evidence on (a) how price framing affects consumers' decision to switch health insurance plans and (b) how the price elasticity of demand for health insurance can be influenced by policymakers through simple regulatory efforts. In 2009, in order to foster competition...

We examine whether the sorting of differently achieving students into differently sized classes results in a regressive or compensatory pattern of class sizes for a sample of national school systems. Sorting effects are identified by subtracting the causal effect of class size on performance...

We examine the impact of family income during childhood on the type of secondary school that German children attend, a good indicator of their lifetime socioeconomic attainment. By contrast with several US child outcome studies, we find that late-childhood income is a more important determinant...

This paper evaluates general achievement effects of choice and competition between private and public schools at the nine-year school level by assessing a radical voucher reform that was implemented in Sweden in 1992. Starting from a situation where the public schools essentially were...

This paper proposes two related measures of educational inequality: one for educational achievement and another for educational opportunity. The former is the simple variance (or standard deviation) of test scores. Its selection is informed by consideration of two measurement issues that have...

Past estimates of the effect of family income on child development have often been plagued by endogeneity and measurement error. In this paper, we use an instrumental variables strategy to estimate the causal effect of income on children's math and reading achievement. Our identification derives...

The paper evaluates the German health care reform of 1997, using the individual number of doctor visits as outcome measure. A new econometric model, the Probit-Poisson-log-normal model with correlated errors, describes the data better than existing count data models. Moreover, it has an...

Pay for performance (P4P) incentives for physicians are generally designed as additional payments that can be paired with any existing payment mechanism such as salary, fee-for-service, and capitation. However, the link between the physician response to performance incentives and the existing...
