Pricing Information Goods in the Presence of Copying

The effects of (private, small-scale) copying on the pricing behavior of producers of information goods are studied within a unified model à la Mussa-Rosen (1978). When the copying technology involves a marginal cost and no fixed cost, producers act independently. In this simple framework, we highlight the trade-off between ex ante and ex post efficiency considerations (how to provide the right incentives to create whilst limiting monopoly distortions?). When the copying technology involves a fixed cost and no marginal cost, pricing decisions are interdependent. We investigate the strategic pricing game by focussing on some significant symmetric Nash equilibria.Information goods, Piracy, Copyright, Pricing

Coordination on Formal vs. de facto Standards: A Dynamic Approach

Formal standards arise out of deliberations of standards-writing organizations, while de facto standards result from unfettered market processes. Therefore, the formers are of a higher quality and legitimacy, but are slower to develop than the latters. To address this trade-off, we analyze a dynamic game where two players choose between one evolving formal standard and one mature de facto standard. The outcome of the game relies on the coordination mechanism used by the players, on the relative value they attach to successful coordination, and on the formal standard's performance at the end of the game.Standardization, Negotiation, Bandwagon

R&D Cooperation or Competition in the Presence of Cannibalization

R&D cooperation is reconsidered in situations where firms direct R&D activities towards a new product that cannibalizes the firms' existing products. For soft cannibalization, the welfare-maximizing arrangement between firms involves, for low R&D costs, the formation of a separate entity that independently chooses both the output level of the new good and the level of R&D expenditures and otherwise, joint decisions about R&D but independent decisions about production. Yet, as cannibalization increases, firms find it unprofitable to market the new good unless they collaborate more narrowly. Merger should then be permitted for the socially desirable introduction of the new good.R&D cooperation, Joint ventures, Cannibalization

Product Differentiation in Successive Vertical Oligopolies

This is a successive oligopoly model with two brands. Each downstream firm chooses one brand to sell on a final market. The upstream firms specialize in the production of one input specifically designed for the production of one brand, but they also produce the input for the other brand at an extra cost. We show that when more downstream firms choose one brand, more upstream firms will specialize in the input specific to that brand, and vice versa. Hence, multiple equilibria are possible and the softening effect of brand differentiation on competition might not be strong enough to induce maximal differentiation. The existence of equilibria and their welfare performance are also examined.Product differentiation, Vertical relationships, Oligopoly

Digital piracy : theory

This article reviews recent theoretical contributions on digital piracy. It starts by elaborating on the reasons for intellectual property protection, by reporting a few facts about copyright protection, and by examining reasons to become a digital pirate. Next, it provides an exploration of the consequences of digital piracy, using a base model and several extensions (with consumer sampling, network effects, and indirect appropriation). A closer look at market-structure implications of end-user piracy is then taken. After a brief review of commercial piracy, additional legal and private responses to end-user piracy are considered. Finally, a quick look at emerging new business models is taken.information good, piracy, copyright, IP protection, internet, peer-to-peer, software, music

Yardstick Competition and Political Agency Problems

This paper analyzes the role of yardstick competition for improving political decisions. We examine how performance comparisons across jurisdictions affect the agency problem resulting from uncertainty about politicians (adverse selection) and their policies (moral hazard). We study two forms of inefficiency: the provision of non-valuable programmes (over-provision) and the failure to provide valuable programmes (under-provision). We find a general neutrality result: yardstick competition does not affect the chance that at least one type of politician in one jurisdiction will take inefficient decision, nor does it affect the risk of underproviding good programmes. However, performance comparisons reduce the risk of providing bad programmes in both jurisdictions.Electoral competition, Yardstick competition

Market Sharing Agreements and Collusive Networks

This paper analyzes the formation of market sharing agreements among firms in oligopolistic markets and procurement auctions. The set of market sharing agreements defines a collusive network, and the paper provides a complete characterization of stable and efficient collusive networks when firms and markets are symmetric. Efficient networks are regular networks, where firms have the same number of market sharing agreements. Stable networks are formed of complete alliances, of different sizes, larger than a minimal threshold. Typically, stable networks display fewer market sharing agreements than the optimal network for the industry and more market sharing agreements than the socially optimal network. When firms or markets are asymmetric, incomplete alliances can form in stable networks, and stable networks may be underconnected with respect to the social optimum.Market sharing, Collusion, Economic networks, Oligopoly, Auctions

Asymmetric Information and Overinvestment in Quality

In a standard adverse selection world, asymmetric information about product quality leads to quality deterioration in the market. Suppose that a higher investment level makes the realization of high quality more likely. Then, if consumers observe the investment (but not the realization of product quality) before purchase, they can infer the probability distribution of high and low quality that may be put on the market. We uncover two effects that may lead the firm to overinvest in quality compared to a market with full information: first, an adverse selection effect according to which a sufficiently large investment can avoid adverse selection and, second, an efficiency effect according to which a larger investment reduces the probability of socially inefficient, low quality products in the market.asymmetric information, product quality

Competitive Imperfect Price Discrimination and Market Power

Two duopolists compete on price in the market for a homogeneous product. They can “profile” consumers, that is, identify their valuations with some probability. If both firms can profile consumers but with different abilities, then they achieve positive expected profits at equilibrium. This provides a rationale for firms to (partially and unequally) share data about consumers or for data brokers to sell different customer analytics to competing firms. Consumers prefer that both firms profile exactly the same set of consumers or that only one firm profiles consumers as this entails marginal cost pricing (so does a policy requiring list prices to be public). Otherwise, more protective privacy regulations have ambiguous effects on consumer surplus
