Nash Equilibrium Search for the Best Alternative

Abstract

In a recent paper, Weitzman (1979) described a policy of "optimal search for the best alternative." The present paper is concerned with the development and characterization of a policy of "Nash equilibrium search for the best alternative." Specifically, it is shown that, under certain monotonicity assumptions, and under the assumption that firms have incomplete information regarding the results of rivals' search behavior, a Nash equilibrium search policy exists and has the same form as Weitzman's optimal search policy.
