Product design and advertisement strategy have been theoretically studied as separate firms decisions. In the present paper, we look at the link between advertisement and product design and we analyze how firms' advertising decisions influence the market effect of product design. We consider a...

We analyze the effects of Geographical Indication (GI) labeling on quality choices and welfare with two vertically differentiated goods, one labelable, the other not. We consider two attributes of these goods: gustatory quality and geographical origin. We investigate two extreme cases of the...

We study competition between an incumbent Credit Rating Agency (CRA) and a sequence of entrant CRAs that are potentially more e¤ective but whose ability in appraising default risk is unproven when they enter the market. We show that free entry competition fails to select the most competent CRA...

In a two-stage game with three firms and two countries, we study the profitability of a domestic merger in the context of an international oligopoly game with differentiated products and in a strategic trade policy environment. In contrast to a completely unregulated economy, we show that the...

We develop a model of interlocking bilateral relationships between upstream manufacturers that produce differentiated goods and downstream retailers that compete imperfectly for consumers. Contract offers and acceptance decisions are private information to the contracting parties. We show that...

The recent subprime crisis and the ongoing Euro zone crisis have generated an enormous interest in the credit rating industry not only among economists but also among average citizens. As a consequence, we have seen an explosion of the economic literature on the industry. The objective of this...

This paper analyzes how the stability of the tacit cooperation within a fringe of sev- eral identical ?rms is a¤ected by the presence of a more e¢ cient ?rm which does not take part in their cooperative agreement. The model assumes that the ?rms of the fringe adopt ?stick and carrot?strategies...

Two-period Cournot competition between n identical firms producing at constant marginal cost and able to store before selling has pure strategy Nash- perfect equilibria, in which some firms store to exert endogenously a leader- ship over rivals. The number of firms storing balances market share...

We study how the presence of a news aggregator affects quality choices of newspapers competing on the Internet. To provide a microfoundation for the role of the aggregator, we build a model of multiple issues where each newspaper chooses quality on each issue. This model captures the...
