What are the welfare effects of a policy that facilitates for insurance customers to privately and covertly learn about their accident risks? We endogenize the information structure in Stiglitz's classic monopoly insurance model. We first show that his results are robust: For a small information...

We study the political determination of the level of social long-term care insurance when voters also choose private insurance and saving amounts. Agents differ in income, probability of becoming dependent and of receiving family help. Social insurance redistributes across income and risk...

In a model where patients face budget constraints that make some treatments unaffordable, we ask which treatments should be covered by universal basic insurance and which by private voluntary insurance. We argue that both cost effectiveness and prevalence are important if the government wants to...

This paper introduces a tractable model of health insurance with both moral hazard and adverse selection. We show that government sponsored universal basic insurance should cover treatments with the biggest adverse selection problems. Treatments not covered by basic insurance can be covered on...

Consumers, when buying health insurance, do not know the exact value of each treatment that they buy coverage for. This leads them to overvalue some treatments and undervalue others. We show that the insurance market cannot correct these mistakes. This causes research labs to overinvest in...

We study a monopoly insurance model with endogenous information acquisition. Through a continuous effort choice, consumers can determine the precision of a privately observed signal that is informative about their accident risk. The equilibrium effort is, depending on parameter values, either...

We evaluate the effect of active labour market programs on the duration of unemployment in a reward or punish system. In Switzerland, unemployment benefits are conditional upon program attendance after 7 months of unemployment duration. In the evaluation we allow for selectivity affecting the...

The share of immigrants in the German social assistance program exceeds their population share and continues to grow. This study evaluates the causes of this phenomenon and tests for the effects of assimilation, cohort, age at migration, and country of origin on immigrant behaviour. It uses...

The single most likely way to leave the unemployment insurance (UI) register in Hungary is not by getting a job but by exhausting entitlement to benefit. Two questions follow. First, what are the implications of the cessation of UI for living standards? Second, does UI exhaustion have much...

Despite increasingly large scale social protection programs in Africa, we have limited evidence on the local political economy of their allocation. We investigate community-based processes for food aid allocation and the role of political and social networks, using the case of Ethiopia in the...
