This paper studies revenue-maximizing mechanisms for a monopolist who expects her buyers to resell in a secondary market. We consider two modes of resale: the first is to a third party who does not participate in the primary market; the second is inter-bidders resale, where the winner in the...

Multinational enterprises (MNEs) have started to populate also regulated sectors. Their linked international activities and credible threats to relocate are then new concerns for regulators. We study a multiprincipal model in which a privately informed MNE (the agent) produces for two countries...

In this paper we analyse a common agency model in which agents can choose with how many principals they want to work, while principals cannot condition contracts on the agent's decision to accept other contracts. In this case of "non-intrinsic" common agency we characterise the equilibrium....

We study international trade of innovative goods subject to scientific uncertainty on consumers' health effects. Trade of these goods is often at the centre of international disputes. We show that a new trade protectionism may arise because of the scientific uncertainty. A free riding effect is...

This paper analyses in a hidden characteristic set-up the design of the optimal price for a firm which is a monopolist at home but competes abroad against foreign firms. As long as diseconomies of scope are not too strong, the optimal price is identified. The price rule depends on the sign of...

We study the regulation of a firm which supplies a regulated service while also operating in a competitive, unregulated sector. If the firm conducts its activities in the two markets jointly, it enjoys economies of scope whose size is the firm's private information, unknown either to the...

We examine the relationship between competition and innovation in an industry where production is polluting and R&D aims to reduce emissions ("green" innovation). We present an n-firm oligopoly where firms compete in quantities and decide their investment in "green" R&D. When environmental...

This paper shows that the introduction of a minimum quality standard can have repercussions on market structure, opening the possibility of predatory behaviour. The predatory equilibrium exists independently of whether or not adjustment costs are present. Moreover, whenever predation is an...
