Web3/1/2016 6 MRS and Convexity Convexity is equivalent to saying that MRS decreases with good 1 Meaning: the amount of good 2 that the person needs to compensate them for the loss of good 1 decreases the more of good 1 they have This is very reasonable: the more you have of one good, the more you’re willing to exchange for some

WebIn the theory of vector measures, Lyapunov's theorem states that the range of a finite-dimensional vector measure is closed and convex. [1] [2] [3] In fact, the range of a non-atomic vector measure is a zonoid (the closed and convex set that is the limit of a convergent sequence of zonotopes ).
