Stochastic dominance conditions are given for n-variate utility functions, when k-variate risk aversion is assumed for k = 1, 2, ..., n. These conditions are expressed through a comparison of distribution functions, as in the well-known univariate case, and through a comparison of random...

Stochastic comparisons of Markov processes have mostly been in terms of transition functions or infinitesimal generators. For Itô processes, that is, solutions of stochastic differential equations, it is possible to obtain very intuitive comparisons in terms of three deterministic functions...

We consider dynamic cooperative games, where the worth of coalitions varies over time according to the history of allocations. When defining the core of a dynamic game, we allow the possibility for coalitions to deviate at any time and thereby to give rise to a new environment. A coalition that...

We consider the optimization problem of a decision maker facing a sequence of coin tosses with an initially unknown probability Θ for heads. Before each toss she bets on either heads or tails and she wins one euro if she guesses correctly, otherwise she loses one euro. We investigate the effect...
