We study the strategic disclosure of demand information and product-market strategies of duopolists. In a setting where both firms receive information with some probability, we show that firms selectively disclose information in equilibrium in order to influence their competitorś product-market...

Vertical integration followed by quantity competition is studied. In the first stage of the game downstream firms simultaneously decide whether to integrate with one of the upstream suppliers. If firms are not able to observe whether their vertically integrated competitor enters the...

This paper analyzes vertical integration incentives in a bilaterally duopolistic industry where input market outcomes are determined by bargaining. Vertical integration incentives are a combination of horizontal integration incentives up- and downstream and depend on the strength of...

We study mass customization in a duopoly game in which the firms' products have different qualities. Whether customization choices are made simultaneously or sequentially is endogenously determined. Specifically, the customization stage of the game involves two periods. Each firm either selects...

We prove that a sufficient condition for the core existence in a n-firm vertically differentiated market is that the qualities of firms' products are equally-spaced along the quality spectrum. This result contributes to see that a fully collusive agreement among firms in such markets is more...

We develop a model of vertical innovation in which firms incur a market entry cost and choose a unique level of quality. Once established, firms compete for market shares, selling to consumers with heterogeneous tastes for quality. The equilibrium of the pricing game exists and is unique within...

Conjectural variation models are popular in empirical research as they infer the degree of market power from real data. IO-theorists, however disapprove it for lack of theoretical foundation arguing that dynamic reactions are forced into a static model with the strategy space and time horizon...
