This paper presents a model of price screening for goods with network effects, by a monopoly seller, and by an entry-deterring monopolist. These products are used in variable quantities by heterogeneous customers, the magnitude of network effects is influenced by gross consumption, rather than...

This paper considers the possibility that a seller can contract with one uninformed buyer prior to an auction involving two potential buyers. In a more general setting than previous literature, strategic ex-ante contracts not only extract rent from entrants, but could also mitigate the...

Received literature have shown that if competing networks are restricted to linear and uniform pricing, high access charges can facilitate collusion; a result that breaks down if we allow for non-linear and discriminatory pricing, however. We show that by adding unbalanced calling pattern to the...

This paper examines the dynamic pricing problem of a durable-good monopolist when product quality is endogenous. It is shown that the relationship between the firm's quality choice and the time-inconsistency problem crucially depends on how the unit production cost varies with quality. The...

New technology is usually expensive and it takes time for manufacturers to make the technology more accessible. In the stereo industry, the first Super Audio Compact Disk (SACD) player made by Sony, SCD-1, sold for $5,000 in 1999; in 2002 the cheapest of Sony's new SACD players, SCD-CE775, had a...

In this paper we develop a formal model of the optimal financing of research projects, when the projects differ in both their success probability and the cost of undertaking. We show that in the benchmark case of publicly observable costs the first best can be achieved. If the costs are private...

A modern firm often employs multiple production technologies based on distinct engineering principles, causing non-convexities in the firm's unit cost as a function of product quality. Extending the model of Mussa and Rosen (1978), this paper investigates how a monopolist's product line design...

In this paper I describe group theoretic methods that can be used for analyzing the boundary problems, which arise when the Hamiltonian method is applied to solve the relaxed problem for the multidimensional screening problem. This technique can provide some useful insights into the structure of...

The Spence model (1975) is extended so that customers’ utility depends on their disposition to the firm in addition to quantity and quality of the good consumed. Disposition is determined by customers’ perception of firm’s pricing and quality decisions, which perception is...
