Personalized pricing has become a reality through digitization. We examine firms' incentives to adopt one of the three pricing schemes: uniform, personalized, or group pricing in a Hotelling duopoly model. There are two types of consumer groups that are heterogeneous in their mismatch costs. We...

We provide a simple model to investigate decisions about vertical separation. The key feature of this model is that more than one input is required for the final product of the downstream monopolist. We show that as the bargaining powers of independent complementary input suppliers grow larger,...

We provide a simple model to investigate decisions on vertical integration/separation. The key feature of this model is that more than one input is required for the final products of the local downstream monopolists. Depending on their cost structure, downstream firms' decisions on vertical...

We propose simple dual-channel models in which an upstream manufacturer trades with a downstream retailer that is able to engage in cost-reducing activities. When the manufacturer determines whether to encroach on the downstream market after observing the retailer's effort level, the threat of...

We provide a theoretical framework to discuss the relation between firm size and vertical structures. The framework is based on a Hotelling model with three downstream and three upstream firms. Each downstream firm procures its input from each upstream firm and the procurement problems affect...

Under a simple Cournot model with vertical relations, when downstream firms engage in process R&D, the profits of upstream firms in which upstream competition exists may be larger than those in which each upstream firm has a bilateral monopoly relation with its buyer (downstream firm).

Using a simple product differentiation model with elastic demands, we investigate the relationship between differentiation strategies and vertical relations. Depending on the competitive structure in the upstream market, three differentiation patterns (maximum, minimum and partial...

We provide a simple model to investigate decisions about vertical separation. The key feature of this model is that more than one input is required for the final product of the downstream monopolist. We show that as the bargaining powers of independent complementary input suppliers grow larger,...

Under a simple Cournot model with vertical relations, when downstream firms engage in process R&D, the profits of input suppliers for which upstream competition exists may be larger than those in which each input supplier has a bilateral monopoly relation with its buyer (downstream firm). This...
