There are two sources of inefficiency of strategic equilibria (SE) in market mechanisms. The first is the oligopolistic effect, which occurs when an agent can single-handedly influence prices. With a continuum of agents we get "perfect competition" and this effect is, of course, wiped out. But...

This is a survey of the economic principles that underlie antitrust law and how those principles relate to competition policy. We address four core subject areas: market power, collusion, mergers between competitors, and monopolization. In each area, we select the most relevant portions of...

This paper demonstrates how, by introducing a generic version of its previously-patented product, a branded firm can influence the equilibrium in the generic segment of the market for the product. This in turn can increase the firm’s profits from selling the branded version. We then use...

We look at an industry of Cournot oligopolists each of which consists of production facilities which enjoy some degree of freedom in deciding their output quantities and that way influence the total output of a firm. This structure can be motivated e.g. the existence of profit centers or by the...

This paper develops a simultaneous-equations panel data econometric model to obtain point estimates of market power and pricing conduct in a representative product-differentiated, oligopolistic food market. The importance of this class of markets is recognized given its prevalence in the food...

This experiment demonstrates principles of decision-making in dynamic oligopolies, especially the difficulties in forming and maintaining cartels. As an illustration of firm behavior under imperfect competition, the game distinguishes between procedurally rational choices and substantively...

This paper is based on the previous work of Appelbaum (Journal of Econometrics, 1979, 9, pp. 283-94; 1982, 19, pp. 287-99). Iwata (Econometrics 1974, 42, pp. 947-66) and Rogers (PhD Dissertation, GeorgeWashington University, 1983).We estimate the degree of market power of an oligopolistic...
