Suppose that wealth, w, is a continuous random variable on [0, 1]. Let F and G denote two distribution functions (lotteries) over w€ [0, 1] where F first order stochastically dominates G. Let EF[w] and Ec[w] denote the expected value of the lotteries F and G respectively. (a) Show both mathematically and graphically that Er[w]> EG[w]. (b) Show both mathematically and graphically that the converse is not true, i.e. EF[w]> EG [w] does not imply that F first order stochas- tically dominates G.
