With welfare implication, we analyze the endogenous choice of competition mode where asymmetric retailers for the cost involve in price discrimination and uniform pricing with an upstream input supplier under vertical contracts. In contrast to previous results, we find that under uniform...

We study firms' strategic delegation decisions when facing consumers with heterogeneous willingness to pay in a Cournot game. We consider a market comprising two consumer groups, with either a high or low willingness to pay. In this market, we first consider the case of symmetric marginal costs...

We examine that the bilateral supplier affects the incentive contracts that owners of retailers offer their managers. Thus, we compare the two models: (1) decentralized bargaining between manufacturers and retailers including two-part tariff contract (2) linear input pricing without bargaining....

We revisit the endogenous choice of price or quantity made by two retailers in a vertical structure with a monopolistic manufacturer under network externalities when the retailers involve in centralized Nash bargaining with the two-part tariff contracts. When comparing integration to separation...

We consider the issue of first- and second-mover advantages in a vertically related market. First, we show that the standard conclusions about sequential-move games under Bertrand and Cournot competitions can change in the context of a vertically related market. This is because an upstream...

We revisit the classic discussion on the endogenous choice of a price or a quantity contract in a vertically related duopoly with a monopolistic upstream firm. We show, from the perspective of the upstream firm, choosing the price contract is a dominant strategy regardless of the nature of...

We investigate the endogenous choice of strategic variable (a price or a quantity) by downstream firms in a two-tier industry in which an upstream firm performs the R&D investment. We show that when the upstream firm offers either linear discriminatory or uniform input price, it is a dominant...
