Some observations are made on the future directions of research in game theory that are to be expected in the next decade.

In a competitive marketplace, the effectiveness of any element of the marketing mix is determined not only by its absolute value, but its relative value with respect to the competition. For example, the effectiveness of a price cut in increasing demand is critically related to competitors'...

The paper provides a general analysis of the types of models with E-Perturbations which have been used recently to discuss the evolution of social conventions. Two new measures of the size and structure of the basins of attraction of dynamic systems, the radius and coradius, are introduced in...

This paper offers a systematic exploration of online feedback mechanism design issues in trading environments with opportunistic sellers, imperfect monitoring of a seller's effort level, and two possible transaction outcomes (corresponding to "high" and "low" quality respectively), one of which...

Online feedback mechanisms harness the bi-directional communication capabilities of the Internet in order to engineer large-scale word-of-mouth networks. Best known so far as a technology for building trust and fostering cooperation in online marketplaces, such as eBay, these mechanisms are...

Online reputation mechanisms are emerging as a promising alternative to more established mechanisms for promoting trust and cooperative behavior, such as legally enforceable contracts. As information technology dramatically reduces the cost of accumulating, processing and disseminating consumer...

This is a preliminary version of a chapter of a prospective book which springs from concerted effort among several researchers in the field of industrial economics. This chapter is devoted to recent development in research on strategic investment. We start with a brief overview on the past...

In an oligopoly supergame, firms' actions in prices and quantities are subject to non-negativity constraints. These constraints can obstruct the practicability of optimal punishment (a la Abreu (1986), Lambson (1987), and Hackner (1996)) in sustaining tacit collusion. Noting that the prospect of...

It has been shown that if buyers have zero search cost and the remainder a common positive search cost, and sellers post prices, then there is a unique symmetric Nash equilibrium-sellers choose a price distribution. We show that increasing the number of search cost types results in another...
