We examine aspects of how new technology may be transferred to firms that use it in a final product market. Should technology transfer take place to a single firm or to more than one, and should it happen gradually or at once? How do the incompleteness of contracts and the nature of product...

We propose a two-sided model with two competing Internet platforms, and a continuum of Content Providers (CPs). We study the effect of a net neutrality regulation on capacity investments in the market for Internet access, and on innovation in the market for content. Under the alternative...

We examine price competition under product-specific network effects, in a duopoly where the products are differentiated horizontally and vertically. When consumers' expectations are not affected by prices, firms may share the market equally, or one firm (possibly the low-quality one) may capture...

We examine a linear city duopoly where firms choose their locations to maximize expected profits, uncertain about how consumers will assess the relative quality of their products. Equilibrium locations depend on the ratio of the expected quality superiority to the strength of horizontal...

We explore the nature of two-part tariff competition between duopolists providing a homogeneous service when consumers differ with respect to their usage rates. Competition in only one price component (the fixed fee or the rate) may allow both firms to enjoy positive profits if the other price...

We analyse a set of simple dynamic models where sellers are capacity constrained over the length of the model. Buyers act strategically in the market, knowing that their purchases may affect future prices. The model is examined when there are single and multiple buyers, with both linear and...

We examine oligopolistic markets with both intrabrand and interbrand competition. We characterize equilibrium contracts involving a royalty (or wholesale price) and a fee when each upstream firm contracts with multiple downstream firms. Royalties control competition between own downstream firms...

We study informative advertising within a random-utility, non-localized competition model of product differentiation. In a symmetric equilibrium, advertisement is sub-optimal when product differentiation is small, and excessive otherwise. Increasing the number of firms may increase or decrease...
