In this chapter we study stochastic orders that compare the “variability” or the “dispersion” of random variables. The most important and common orders that are studied in this chapter are the convex and the dispersive orders. We also study in this chapter the excess wealth order (which is also called the right spread order) which is found to be useful in an increasing number of applications. Various related orders are also examined in this chapter.
