One smart agent
TL;DR: In this article, the authors propose an equilibrium concept for a class of games in which players make irreversible costly decisions, which is weaker than perfect Nash equilibrium, and involves combining a form of "survivor principle" with an assumption regarding entry.

Competition and the Efficiency of Markets for Technology
TL;DR: In this article, a condition for the equilibrium timing of licensing and examine how factors such as the intensity of competition between potential buyers influence it, showing that a wide array of different explanations, based on differences in information, beliefs or risk profiles, lead to the same qualitative results.

The Herfindahl-Hirschman Index and the Distribution of Social Surplus
Yossi Spiegel,Yossi Spiegel +1 more
TL;DR: In this article, the authors show that in a broad range of oligopoly models where firms have (not necessarily identical) constant marginal cost, HHI is an increasing function of the ratio of producers' surplus and consumers' surplus.

On the Microfoundation of Linear Oligopoly Demand
Iwan Bos,Dries Vermeulen +1 more
TL;DR: In this article, the authors present an alternative microeconomic foundation by deriving the same demand system directly from a population of heterogeneous buyers, which can be easily adapted to different demand specifications.

The Theory of Industrial Organization
TL;DR: The Theory of Industrial Organization as discussed by the authors is the first primary text to treat the new industrial organization at the advanced-undergraduate and graduate level Rigorously analytical and filled with exercises coded to indicate level of difficulty, it provides a unified and modern treatment of the field with accessible models that are simplified to highlight robust economic ideas.

Monopolistic competition and optimum product diversity
Avinash Dixit,Joseph E. Stiglitz +1 more
TL;DR: In this article, Pettengill tests whether there is an excessive number of firms in a monopolistically competitive equilibrium by a device of considerable expository merit, and redistributes the resources thus released equally over the remaining firms in the sector, to see if welfare can be improved.

Price and quantity competition in a differentiated duopoly
Nirvikar Singh,Xavier Vives +1 more
TL;DR: The authors analyzes the duality of prices and quantities in a differentiated duopoly and shows that if firms can only make two types of binding contracts with consumers, the price contract and the quantity contract, it is a dominant strategy for each firm to choose the quantity (price) contract, provided the goods are substitutes (complements).

Discrete Choice Theory of Product Differentiation
TL;DR: This important study shows that an understanding of product differentiation is crucial to understanding how modern market economies function and that differentiated markets can be analyzed using discrete choice models of consumer behavior.
