Dealing with the consequences of climate change will put an increasing burden on public and private finances. We use the example of floods in a survey experiment among 8,000 German households to elicit households' preferences for climate adaptation policies. In Germany, as in many countries, we...

Commitment devices offer an opportunity to restrict future choices. However, strict commitments may deter participation. Using a school-based commitment savings program for children to save for educational expenses in Uganda, we compare an account fully-committed to school expenses to an account...

Das Solidaritätsprinzip prägt die gesetzliche Krankenversicherung (GKV). Bislang leisten rund vier von zehn Versicherten einen Solidarbeitrag, weil sie mehr einzahlen, als es ihren alters- und geschlechtsabhängigen Durchschnittsausgaben entspricht. Andersherum ist es bei sechs von zehn...

Workers' compensation insurance provides cash payments and medical benefits to workers who incur a work-related injury or illness. Many features of the workers' compensation program parallel features of proposed mandated employer-paid health insurance plans. This paper empirically examines the...

The aging of the populations in the OECD countries has prompted various calls for reforming the existing pay-as-you-go (PAYG) pension systems. Currently, there is renewed discussion in the United States about partial privatization where a fraction of the social security payroll tax would be...

In the modern welfare state a substantial part of an individual's tax bill is transferred back to the same individual taxpayer in the form of social transfers. This provides a rationale for financing part of social insurance through mandatory savings accounts. We analyze the behavioral and...

Die bisherige Erfahrung mit der Teilprivatisierung der gesetzlichen Rente zeigt, dass die ursprünglichen Versprechen weder hinsichtlich der Leistungsfähigkeit noch der Generationsgerechtigkeit erfüllt werden. Sowohl angesichts der aktuellen Situation als auch aufgrund von theoretischen...

Solidarität bedeutet in der GKV zweierlei - auf der einen Seite ein Risikoausgleich zwischen niedrigen und hohen Risiken, die alle entsprechend einer durchschnittlichen Schadenserwartung zu gleichen Bedingungen versichert werden; auf der anderen Seite ein sozialer Ausgleich, der durch die...

The welfare associated with public insurance is often difficult to quantify. Relative to private insurance, a fundamental difficulty is that public insurance is typically compulsory, so the demand for coverage is unobserved and thus cannot be used to analyze welfare. However, in many public...

Commitment devices offer an opportunity to restrict future choices. However, if severe restrictions deter participation, weaker restrictions may be a more effective means of changing behavior. We test this using a school-based commitment savings device for educational expenses in Uganda. We...

Wie ist es möglich, dass in Deutschland - ganz anders als in den meisten anderen Ländern - seit 20 Jahren der Rentenbeitragssatz kontinuierlich sinkt, obwohl die Anzahl der Rentenbezieherinnen und -bezieher in demselben Zeitraum gestiegen ist? Welche Folgen hätte die Anhebung der...
