A Model of Duopoly Suggesting a Theory of Entry Barriers

Dixit, Avinash·1979·The Bell Journal of Economics

Abstract

The descriptive and empirical literature in Industrial Organization abounds with reference to economies of scale, product differentiation, and absolute advantages in cost or demand enjoyed by some firms over others. In particular, they feature prominently in Bain's list of barriers to entry in. However, textbook models of oligopoly often abstract away from all these features, and assume a homogeneous product with equal constant costs for all firms in the industry. The real-world complexities are confined to informal remarks, suggesting vague modifications of the formal results. This happens even in such outstanding treatments as those of Feller and Scherer.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
