"Multiproduct Activity Matter in an Experimental Differentiated Oligopoly"
JEL codes: C72, C9, L1
Abstract: In a symmetric differentiated experimental oligopoly with multiproduct firms we test the predictive power of the corresponding Bertrand-Nash equilibria. Subjects are not informed on the specification of the underlying demand model. In the presence of intense multiproduct activity and, provided that a parallel pricing rule is imposed to multiproducts firms, strategies tend to confirm that non-cooperative multiproduct solution.
