Slutsky's theorem proof assignment
WebbNote that the requirement of a MGF is not needed for the theorem to hold. In fact, all that is needed is that Var(Xi) = ¾2 < 1. A standard proof of this more general theorem uses the characteristic function (which is deflned for any distribution) `(t) = Z 1 ¡1 eitxf(x)dx = M(it) instead of the moment generating function M(t), where i = p ¡1.

Hence, thesign of \A\isthesame as (―I)""1 and our theorem holds. Proof of Lemma 1. In thisproof, we abbreviate (p,m) and x fornotational sim-

Webb3 nov. 2015 · We now have enough machinery to give a quick proof of the central limit theorem: Proof: (Fourier proof of Theorem 8) We may normalise to have mean zero and variance . By Exercise 25, we thus have. for sufficiently small , or equivalently. for sufficiently small . Applying , we conclude that. as for any fixed . WebbExercise 1. Slutsky (Cobb-Douglas) The utility function is u = x 1 x 2 , and the budget constraint is m = p 1 x 1 + p 2 x 2. a) Derive the optimal demand curve for good 1, x 1 (m,p 1 ), and good 2, x 2 (m, p 2 ). b) Assume m=160, p 1 =8 and p 2 =1.

WebbThe Slutsky conditions are abstract, without a straightforward interpretation, but they are equivalent to more easily interpretable revealed preference axioms. Slutsky negative semidefiniteness is equivalent to a weak version of the weak axiom, cf. Kihlstrom, et al. (1976). Slutsky symmetry is equivalent to Ville's axiom, i.e.
