I present a game-theoretic model where economic competition and attention competition are interdependent. On the one hand the effort to attract consumer attention depends on the value of attention to the firm which depends on the grade of price competition among all perceived firms. On the other...

In the economic literature on market competition, firms are often modelled as individual decision makers and the internal organization of the firm is neglected (unitary player assumption). However, as the literature on strategic delegation suggests, one can not generally expect that the behavior...

This paper reconsiders the literature on the irrelevance of privatization in mixed markets, addressing both quantity and price competition in a duopoly with differentiated products. By allowing for partially privatizing a state-controlled firm, we explore competition under different timings of...

This paper studies the welfare consequences of a vertical merger that raises rivals costs when downstream competition is à la Cournot between firms with constant asymmetric marginal costs. The main result is that such a vertical merger can nevertheless improve welfare if it involves a...

We model duopoly competition between two platforms. They operate in a two-sided market where agents are heterogeneous on both sides of the market and are allowed to multihome. Network effects are captured within a vertical differentiation framework. Under single-homing there exists an interior...

This paper studies the welfare consequences of a vertical merger that raises rivals' costs when downstream competition is a la Cournot between firms with constant asymmetric marginal costs. The main result is that such a vertical merger can nevertheless improve welfare if it involves a...

This paper investigates the strategic effect of bundling when a multi-product firm producing two complements faces competition in both markets. I consider a demand structure where both Cournot and Bertrand competition can be evaluated. Bundling is completely ineffective when firms compete in...
