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 explore the manufacturer's incentives to use a dual-channel supply chain rather than only a direct or an indirect channel in simultaneous price competition. We first revisit the demand formulation widely used in the context of channel analysis and introduce a different demand formulation...

In a two-firm model where each firm sells a high-quality and a low-quality version of a product, customers differ with respect to their brand preferences and their attitudes towards quality. We show that the standard result of quality-independent markups crucially depends on the assumption that...

In this paper, we tackle the dilemma of pruning versus proliferation in a vertically differentiated oligopoly under the assumption that some firms collude and control both the range of variants for sale and their corresponding prices, likewise a multiproduct firm. We analyse whether pruning...

We analyze firms' decisions to adopt a vertical integrated or decentralized structure taking into account the characteristics of both the final good competition and the R&D process. We consider two vertical chains, where R&D is conducted by upstream sectors. R&D investment determines the...

Spanish Abstract: Este artículo analiza un modelo de competencia a la Bertrand con bienes diferenciados, que permite determinar las decisiones óptimas de las empresas cuando los dueños pueden usar la integración vertical y los contratos gerenciales como herramientas estratégicas. En...

This paper first introduces an approach relying on market games to examine how successive oligopolies do operate between downstream and upstream markets. This approach is then compared with the traditional analysis of oligopolistic interaction in successive markets. The market outcomes resulting...

We study how vertical integration in a two-sided media market affects investments in premium content. We show that a content provider provides the premium content exclusively to a platform, regardless of what the vertical structure of the industry is. However, a vertically integrated content...

This paper illustrates the effect of market size on the decision of whether or not firms should vertically integrate or disintegrate. We use a model of two successive stages of production with Cournot competition in each stage. In this model, firms choose to specialize (either upstream or...
