Price vs Quantity in a Repeated Di¤erentiated Duopoly1
نویسندگان
چکیده
We investigate the choice of market variable, price or quantity, of an optimal implicit cartel. If the discount factor is high, the cartel can realize the monopoly pro...t in both cases. Otherwise, it is optimal for the cartel to rely on quantities in the collusive phase if goods are substitutes and prices if goods are complements. The reason is that this minimizes the gains from deviations from collusive play.

Endogenous Choice of Capacity and Product Innovation in a Di¤erentiated Duopoly¤
We model a symmetric duopoly where ...rms choose whether to be quantity setters or price setters by deciding the optimal capacity; undertake R&D activity to determine the degree of di¤erentiation; and ...nally compete in the market. Two games are proposed, where investment decisions follow di¤erent sequences. We assess price and quantity decisions, ...nding a set of equilibria where the choice ...

This research presents a futuristic framework for Quality of Service (QoS) mapping between practically categorized packet video and relative di erentiated service (Di Serv) network employing uni ed priority index and adaptive packet forwarding mechanism under a given pricing model (e.g., Di Serv level di erentiated price/packet). Video categorization is based on the relative priority index (RPI...
متن کاملHome Market E¤ect and its Extensive and Intensive Margins: The Role of Factor Endowments
This paper develops a factor proportions driven monopolistic competition model of trade to examine how home-market e¤ects (HME) vary across countries and industries. I extend the multi-sector framework of Hanson and Xiang (AER 2004) to a two factor case where xed cost of starting a business is more capital intensive than the marginal cost. Countries with di¤erent factor endowments have di¤eren...
متن کاملProduct perishability and multistore grocery shopping
Perishability, a largely unconsidered characteristic of consumer goods, is shown to play an important role in planned multistore shopping behavior. We present a model of consumers as cost minimizing inventory managers, who choose between two stores di!erentiated on location and price, and who purchase perishable and nonperishable goods. We show that the interaction between perishability of good...
متن کاملParis Metro Pricing: The minimalist di erentiated services solution
Di erentiated services for the Internet are undergoing intensive development. It is widely accepted that they will require usage sensitive pricing. The Paris Metro Pricing (PMP) proposal is to rely on pricing alone to provide di erentiated services. PMP is the simplest di erentiated services system in terms of complexity.
