WebThe key technical result underlying our analysis of the Scalable Actor Critic algorithm is a ﬁnite-time analysis of a general stochastic approximation scheme featuring inﬁnite-norm contraction and state aggregation (Theorem 3.1). We apply this result to networked MARL using the local neighborhood of each agent to provide state aggregation (SA). WebGorman’s (1981) theorem implies that higher order polynomials in log income will have a linear relationship to the lower-order terms since the matrix of coefﬁcients is at most of …

"WebI This is because of the Gorman Aggregation Theorem. I If the indirect utility function is in the Gorman form v i(p;W i) = a i(p) + b(p)W i; where p is the price vector and W i is the wealth. From Roy’s identity, the Walrasian demand function is c i(p;W i) = g i(p) + h(p)W i; and thus the aggregate demand C(p;W i) = X i g i(p) + h(p) X i W i; " - Gorman's aggregation theorem
