A large literature on ex ante moral hazard in income insurance emphasizes that the individual can affect the probability of an income loss by choice of lifestyle and hence, the degree of risk-taking. The much smaller literature on moral hazard ex post mainly analyzes how a ?moral hazard...

In this paper we treat an individual's health as a continuous variable, in contrast to the traditional literature on income insurance, where it is regularly treated as a binary variable. This is not a minor technical matter; in fact, a continuous treatment of an individual's health sheds new...

Several empirical studies provide evidence that their actual health state affects people's attitudes towards health and medical care in hypothetical health states. In the tradition of behavioural economics this paper considers the actual health state as a point of reference and builds a model...

The standard economic analysis of the insured-insurer relationship under moral hazard postulates a simplistic setup that hardly explains the many features of an insurance contract. We extend this setup to include the situation that the insured was facing at the time of the accident and the...

Public disability insurance (DI) programs in many countries face pressure to reduce their generosity in order to remain sustainable. In this paper, we investigate the welfare effects of giving a larger role to private insurance markets in the face of public DI cuts. Exploiting a unique reform...

This paper studies the propensities of the U.S. population to seek a full dose of vaccinations against the COVID-19 pandemic. Beyond the consideration of vaccine dissemination at the disaggregated or the local level, the main focus of this study is on determining whether a lack of health...

We provide novel evidence of how an innovative market-based solution using remote-sensing technology can mitigate conflict. Droughts are a major driver of conflict in Africa, particularly between nomadic pastoralists and sedentary farmers, and climate change is predicted to intensify this...

This paper uses stochastic simulations on calibrated models to assess the optimal degree of reliance on fun ded pensions and on a particular type of unfunded (PAYG) pension. Surprisingly little is known about the optimal split between funded and unfunded systems when there are sources of...

Socio-economic differences in longevity have fuelled a debate whether pension systems have a regressive bias favouring groups with a high life expectancy. We show that the distributional implications of such pooling depend critically on the benefit profile across age/time, which in turn is...

We model natural disaster insurance in France. We explicitly take into account the main institutional features of the system, such as the uniform premium rate in both high and low risk regions and the existence of a state reinsurance company. Our model indicates that the institutional set-up is...
