This work shows how long-term investors can benefit from adding volatility as an asset class to their portfolio. Two types of "structural" exposure – long implied volatility and long volatility risk premium – are now simple to implement. Implied volatility exposure can be used to...

We consider a life-cycle model with bequest motives, and assume that the individual does not know his/hersurvival probability and has maxmin utility preferences; we show that it is optimal not to annuitize but to purchase pure life insurance policies instead.

In the Rothschild and Stiglitz model, assuming differences in risk aversions may lead to unusual equilibrium configurations like multiple equilibria, equilibrium positive profits, or random contracts. We characterize the various types of equilibria and give results on the determinants of the...

This paper investigates the impact of chronic diseases on insurance contracts with adverse selection. We use a bi-dimensional utility function (wealth and health status). We prove that the introduction of chronic diseases influences the equilibrium of insurance market. We characterize conditions...

This paper studies efficient risk-sharing rules for the concave dominance order. For a univariate risk, it follows from a comonotone dominance principle, due to Landsberger and Meilijson (1994) [27], that efficiency is characterized by a comonotonicity condition. The goal of the paper is to...

The purpose of this paper is to study the effect of operational, and market risks disclosures on investors’ disagreements about French firms’ value. The paper provides evidence on risks reporting efficiency in reducing investors’ disagreements about the implication for firm’s value of...
