The present paper is concerned with providing a core model to address the issue of firms simultaneously competing in both prices and quantities (capacity levels) within a simple duopoly market setting where products are asymmetrically differentiated by endogenous quality location. A three-stage...

This paper considers the optimal public ownership policy of an upstream firm which competes with a foreign private rival. Both firms supply a produced input to the domestic and foreign downstream firms that compete in an export market. The paper shows that complete privatization of the domestic...

Italian Abstract: Dopo aver definito la differenziazione verticale come una caratterizzazione oggettiva della qualità che da luogo ad una indiscutibile utilità o produttività marginale crescente nella qualità, utilizzando il modello classico di Shaked e Sutton vengono determinati prezzi e...

The unprecedented access of firms to consumer level data not only facilitates more precisely targeted individual pricing but also alters firms' strategic incentives. We show that exclusive access to a list of consumers can provide incentives for a firm to endogenously assume the price leader's...

We consider the issue of first- and second-mover advantages in a vertically related market. First, we show that the standard conclusions about sequential-move games under Bertrand and Cournot competitions can change in the context of a vertically related market. This is because an upstream...

We investigate the endogenous choice of strategic variable (a price or a quantity) by downstream firms in a two-tier industry in which an upstream firm performs the R&D investment. We show that when the upstream firm offers either linear discriminatory or uniform input price, it is a dominant...

We examine that each manufacturer decides on whether or not to delegate to its retailer in the presence of network externalities. In this paper, we show a trade-off between competition and network size. Vertical separation has the advantage of softening a retailing competition, but has the...

The unprecedented access of firms to consumer level data facilitates more precisely targeted individual pricing. We study the incentives of a data broker to sell data about a segment of the market to three competing firms. The segment only includes a share of the consumers in the market around...

The unprecedented access of firms to consumer level data not only facilitates more precisely targeted individual pricing but also alters firms' strategic incentives. We show that exclusive access to a list of consumers can provide incentives for a firm to endogenously assume the price leader's...

We review the economics of superstars, originally developed for stars in traditional media, and discuss whether they are applicable for the (allegedly) novel phenomenon of stars in social media (influencer, micro-celebrities). Moreover, we analyse potentially new factors for creating social...
