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...

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 model investments in capacity in a homogeneous product duopoly facing uncertain demand growth. Capacity building is achieved through adding production units that are durable and lumpy and whose cost is irreversible. There is no exogenous order of moves, no first-mover or second-mover...

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...
