''A generalization of the Dorfman-Steiner Formula: Advertising spillovers under imperfect competition'' |
( 2020, Vol. 40 No.2 ) |
|
|
By using Weyl and Fabinger's (2013) conduct parameter approach, this note generalizes the Dorfman-Steiner formula to include the case of imperfect competition and advertising spillovers, and thereby extends Forbes' (1986) analysis of quantity competition. Furthermore, this generalization also allows the possibility of coordinated/collusive pricing by introducing Edgeworth's (1881) “coefficient of sympathy” as its micro-foundation, and generalizes Lambin's (1970) and Schmalensee's (1972) expressions of the Dorfman-Steiner formula in oligopoly. |
