This paper explores the introduction of collective risk-reallocation elements in defined contribution pension contracts. We consider status-contingent, age-contingent and asset-contingent arrangements to reallocate risk among participants. Eliminating asset market risk for the retired raises...

In this paper, we consider the multi-period joint capacity allocation and job assignment problem. The goal of the … planner is to simultaneously decide on allocating resources across the J different supply nodes, and assigning of jobs of I … test our model against state-of-the-art models that focus solely on the capacity allocation or job assignment decisions, in …

Unlike classic risk sharing problems based on expected utilities or convex risk measures, quantile-based risk sharing games exhibit two special features. First, quantile-based risk measures (such as the Value-at-Risk) are often not convex, and second, they ignore some part of the distribution of...

We extend the Rothschild and Stiglitz (1970, 1971) notion of increasing risk to families of random variables and in this way link their approach to the concept of stochastic processes which are increasing in the convex order. These processes have been introduced in seminal work by Strassen...

We revisit Machina's local utility as a tool to analyze attitudes to multivariate risks. Using martingale embedding techniques, we show that for non-expected utility maximizers choosing between multivariate prospects, aversion to multivariate mean preserving increases in risk is equivalent to...

As societies are increasingly concerned with risks, it is important to evaluate risks not only from an individual, but also from a societal perspective. This paper analyzes preferences of impartial spectators over different types of risk allocations across a group of individuals. We consider...
