In a recent paper, Alipranti et al. (2014, Price vs. quantity competition in a vertically related market, Economics Letters, 124: 122-126) show that in a vertically related market Cournot competition yields higher social welfare compared to Bertrand competition if the upstream firm subsidises...

We analyze the competitive effects of backward vertical integration when firms exert market power upstream and compete à la Cournot downstream. Contrasting with previous literature, a small degree of vertical integration is always procompetitive because efficiency gains dominate foreclosure...

This paper studies commodity taxation in a model featuring heterogeneous consumers, imperfect competition, and tax salience. We derive new formulas for the incidence and marginal excess burden of commodity taxation highlighting interactions between tax salience and market structure. We estimate...

This paper provides a comprehensive analysis of welfare effects under multiple policy interventions and non-governmental external changes. Specifically, in relation to multi-dimensional pass-through, we provide “sufficient statistics” formulas for welfare measures under a fairly general...

This paper analyses a model of vertical product differentiation with one incumbent and one entrant firm. It is shown that if firms can produce only one quality level welfare in this entry game can be lower than in monopoly. This is the case if qualities are strategic complements because the...

Retailers act as intermediaries between manufacturers and consumers. When retailers sell their own products alongside those of manufacturers, what is the effect on competition? Further, how does this effect hinge on market power? In this paper, I theoretically and empirically study the effect of...
