Abstract
Abstract We study Butters’s (1977. “Equilibrium Distributions of Sales and Advertising Prices.” The Review of Economic Studies 44 (3): 465–91) model under concave advertising costs, and determine a class of cost functions such that each seller sends the same finite number of ads in equilibrium. Then we consider the limit economy where the number of buyers and sellers grow indefinitely, and show that the equilibrium of the finite economy does not converge to an equilibrium in the limit economy.
期刊介绍：
We welcome submissions in all areas of economic theory, both applied theory and \"pure\" theory. Contributions can be either innovations in economic theory or rigorous new applications of existing theory. Pure theory papers include, but are by no means limited to, those in behavioral economics and decision theory, game theory, general equilibrium theory, and the theory of economic mechanisms. Applications could encompass, but are by no means limited to, contract theory, public finance, financial economics, industrial organization, law and economics, and labor economics.
