Many competitive health insurance markets adjust payments to participating health plans according to their enrollees' risk - including based on diagnostic information. We investigate responses of German health plans to the introduction of morbidity-based risk adjustment in the Statutory Health...

For policy reforms to increase a society's welfare, reliable information on people's prefer-ences and expectations is crucial. Representative opinion polls, often involving simplified questions about the complex topics under debate, are an important source of information for both policy-makers...

Advances in information technology have improved the administrative feasibility of redistribution based on lifetime earnings recorded at the time of retirement. We study optimal lifetime income taxation and social insurance in an economy in which redistributive taxation and social insurance...

We examine the impact of a policy reform that gave employees in a municipality extended rights to self-declare sickness absence. To identify the effect of bypassing the physician as an absence certifier we contrast the development of absence in the reform municipality with absence in similar...

We investigate the impact on work absence of a massive reduction in paid sick leave benefits. We exploit a policy change that only affected public sector workers in Spain and compare changes in the number and length of spells they take relative to unaffected private sector workers. Our results...

Competition among physicians is widespread, but compelling empirical evidence on the impact on service provision is limited, mainly due to lack of exogenous variation in the degree of competition. In this paper we exploit that many GPs, in addition to own practice, work in local emergency...

In 1996, statutory sick pay was reduced for private sector workers in Germany. Using the empirical observation that trade union members are dismissed less often than non-members, we construct a model to predict how absence behaviour will respond to the sick pay reform. We show that union members...

Purchasing life insurance is for the welfare of young children, par-ticularly preteens, who are liquidity constrained. In this paper, we present a life cycle model of life insurance that takes into account the ages of these young beneciaries. We show that, as the child ages, the need for...

In this paper we address the question how the generosity of the benefit rule of the German public pension system has changed during the past three decades and how this development can be explained by demographic changes. Firstly, we illustrate the political risk of benefit rule changes for...

The traditional approach to flexible retirement (e.g. NDC) neglects the impact of asymmetric information on actuarial fairness (neutrality). The mechanism design approach (e.g. Diamond, 2003) gives up the requirement of neutrality and looks for a redistributive second-best benefit-retirement-age...
