This paper extends a useful property of the increasing convex order to the multivariate orthant convex order. Specifically, it is shown that vectors of sums of comonotonic random variables dominate in the orthant convex order vectors of sums of random variables that are smaller in the increasing...

In this letter, we show that the results presented by Jindapon and Neilson (2007) for changes in risk à la Ekern (1980) can be generalized to mean-preserving stochastic dominance changes, with appropriate and simple additional conditions on the utility function.

Marginal Conditional Stochastic Dominance (MCSD) developed by Shalit and Yitzhaki (1994) gives the conditions under which all risk-averse individuals prefer to increase the share of one risky asset over another in a given portfolio. In this paper, we extend this concept to provide conditions...

The present work complements the recent paper by Barz and Müller (2012). Specifically, upper and lower bounds are derived for the force of mortality when one-year death probabilities are given, assuming a monotonic, convex or concave shape. Based on these bounds, worst-case scenarios are...
