We consider a firm acting strategically on behalf of its shareholder. The price normalization problem arising in general equilibrium models of imperfect competition can be overcome by using the concept of real wealth maximization. This concept is based on shareholders´ aggregate demand and does...

We consider the issues of endogenous timing and first versus second-mover advantage in differentiated-product Bertrand duopoly with asymmetric linear costs. First, we provide a thorough set of results in the cases where prices are either strategic substitutes and/or complements, dispensing with...

We analyze informational lobbying in the context of multi-member legislatures. We show that a single decision maker and a decentralized majoritarian legislature provide widely different incentives for interest groups to acquire and transmit policy relevant information. The paper also shows a...

Interest groups can influence political decisions in two distinct ways: by offering contributions to political actors and by providing them with relevant information that is favorable for the group. We analyze the conditions under which interest groups are more inclined to use one or the other...

This paper studies competition between a small number of suppliers and a single buyer, (or an auction with a small number of bidders and a single seller) when total demand (supply) is uncertain. It is well known that when a small number of suppliers compete in supply functions the service is not...

We compare simultaneous versus sequential moves in R&D decisions within an asymmetric R&D/Cournot model with linear demand (for differentiated products), general R&D costs, and spillovers. Simultaneous play and sequential play (with and without a specified leader) can emerge as appropriate...

In this paper we analyze the welfare properties of the set of Drèze equilibria for economies with incomplete markets and firms. The well known fact that a Drèze equilibrium need not be constrained Pareto optimal is often attributed to a lack of coordination between firms. We show that there...

This paper studies different explanations given for the "price decline anomaly" in sequential auctions, a phenomenon also known as the "afternoon effect". It surveys the dedicated theoretical models and then explores the influence of the institutional or market characteristics (of the sale) on...

We model a two period monopoly market with two-sided quality uncertainty. In first period, seller gathers information about consumers´ tastes upon observing its sales. In second period, seller may or may not deliver the information. If monopolist must commit either to reveal or conceal...

Antitrust practitioners and consumers protectionists often argue that market transparency should be improved to allow consumers to shop around for bargain prices thereby putting pressure on oligopolists´ pricing. We model how transparency, interpreted as the comparability from the point of view...
