Moral hazard and adverse selection create inefficiencies in private health insurance markets. The authors use claims data from a large firm to study the independent roles of both moral hazard and adverse selection. Previous studies have attempted to estimate moral hazard in private health...

The identification of information problems in different markets is a challenging issue in the economic literature. This paper performs tests of residual asymmetric information in the French automobile insurance market for the 1995-1997 period. This market is characterized by the presence of a...

We develop a test for adverse selection and use it to examine private health insurance markets. In contrast to earlier papers that consider a purely private system or a system in which private insurance supplements a public system, we focus our attention on a system where privately funded health...

This paper includes couples on the demand side and analyses their implications on the problem of adverse selection in the annuity market. First, we examine the pooling equilibrium for individual-life annuities and show that in the presence of couples the rate of return on individuallife...

We examine equilibria in competitive insurance markets with adverse selection when wealth differences arise endogenously from unobservable savings or labor supply decisions. The endogeneity of wealth implies that high risk individuals may ceteris paribus exhibit the lower marginal willingness to...

In funded defined benefit pension schemes, contribution and accrual rates are typically age-independent. This implies that pension contributions are front-loaded. As contributions and accruals usually relate to earned labor income, this front-loading may affect labor market efficiency. For it...

While risk selection within the German public health insurance system has received considerable attention, risk selection between public and private health insurers has largely been ignored. This is surprising since - given the institutional structure - risk selection between systems is likely...
