On the existence of Cournot equilibrium

Full text - MIT Libraries
W Novshek - The Review of Economic Studies, 1985 - restud.oxfordjournals.org
Abstract This paper examines the existence of n-firm Cournot equilibrium in a market for a
single homogeneous commodity. It proves that if each firm's marginal revenue declines as
the aggregate output of other firms increases (which is implied by concave inverse ...

Fulfilled expectations Cournot duopoly with information acquisition and release

W Novshek… - The Bell Journal of Economics, 1982 - JSTOR
This article studies the fulfilled expectations equilibrium for a Cournot duopoly model in
which firms acquire information about uncertain linear demand. Several propositions are
established concerning the incentives to acquire and release information in this duopoly ...

Cournot equilibrium with free entry

[PDF] from nyu.edu
Full text - MIT Libraries
W Novshek - The Review of Economic Studies, 1980 - JSTOR
Despite the fact that the assumptions underlying perfect competition never actually hold, the
use of the competitive model, as an idealization, is justified if the predictions of the model
approximate the outcomes of situations it is used to represent. In partial equilibrium ...

Cournot and Walras equilibrium

[PDF] from princeton.edu
W Novshek… - 1978 - books.google.com
This paper unifies the two leading classical concepts of equilibrium for an economy: Walras
equilibrium and Cournot equilibrium. The theory pro-vides a fresh setting for the study of
competitive markets, and leads to a description of economic equilibrium which differs in ...

General equilibrium with free entry: A synthetic approach to the theory of perfect competition

Full text - MIT Libraries
W Novshek… - Journal of Economic Literature, 1987 - JSTOR
The essay is dedicated to the memory of Tjalling Koopmans (1910-1985). Our purpose has
been to communicate to the nonspecialist an aspect of mathematical economics that has
been developed since Koopman's masterful exposition of general equilibrium theory ( ...

Marginal consumers and neoclassical demand theory

[PDF] from princeton.edu
W Novshek… - The Journal of Political Economy, 1979 - JSTOR
We extend the neoclassical theory of demand so that marginal consumers play a significant
role in the determination of the elasticity of aggregate demand. Price-induced demand
changes are decomposed into three effects: an aggregate substitution effect, an ...

Finding all n-firm Cournot equilibria

Full text - MIT Libraries
W Novshek - International Economic Review, 1984 - JSTOR
Industrial organization models commonly employ the Cournot equilibrium concept but often
only the symmetric equilibria are considered. This is unsatisfactory when performing
comparative statics unless it can be shown that no other (stable) equilibria exist. Problems ...

Perfectly competitive markets as the limits of Cournot markets

W Novshek - Journal of Economic Theory, 1985 - Elsevier
Abstract A perfectly competitive, partial equilibrium market for a single homogeneous good
with a (bounded) continuum of infinitesimal firms is considered. Cost functions are
essentially unrestricted and are allowed to vary smoothly across firms. A sequence (net) of ...

Walrasian equilibria as limits of noncooperative equilibria. Part II: pure strategies

W Novshek… - Journal of Economic Theory, 1983 - Elsevier
Abstract We examine the connection between Walrasian equilibria of a limit economy (with
infinitesimal firms) and noncooperative (Cournot) equilibria of approximating finite
economies (with significant firms). Nonconvex production sets, decreasing returns in the ...

[BOOK] Small efficient scale as a foundation for Walrasian equilibrium

[PDF] from princeton.edu
W Novshek… - 1979 - princeton.edu
We are concerned with a formal description of perfect competition in which small efficient
scale and the entry of firms occupy a central role. The set of aggregate technological
possibilities for the economy is obtained by summing the production sets of a very large ...

Equilibrium in a simple price-location model

Full text - MIT Libraries
E Kohlberg… - Economics Letters, 1982 - Elsevier
Abstract In a spatial model with endpoints we show that when consumers have downward
sloping (rather than perfectly inelastic) demand, a price-location equilibrium (with price
undercutting barred) exists if the market is sufficiently long relative to the number of firms.

Bertrand equilibria with entry: limit results

Full text - MIT Libraries
W Novshek… - International Journal of Industrial …, 2003 - Elsevier
We study the limiting behaviour of Bertrand equilibria (where firms must supply the whole of
the demand coming to them) for two different cases, first when entry is exogenous, and
second when it is free. The limit equilibrium set is characterised for both cases for a large ...

Information disaggregation and incentives for non-collusive information sharing

Full text - MIT Libraries
W Novshek… - Economics Letters, 1998 - Elsevier
When shocks to demand intercepts are not perfectly correlated, we show by example that
sharing non-anonymous, disaggregated information is sometimes a Nash equilibrium. It also
improves consumers' surplus and total welfare. This contradicts conclusions based on ...

Money-back guarantees and market experimentation

We study the use of money-back guarantees as a form of market experimentation in a
market for experience goods with repeat purchases. We show that extending the customer
base in the second-period by using a money-back guarantee can be optimal only if a ...

Supply and marginal firms in general equilibrium

Full text - MIT Libraries
W Novshek… - Economics Letters, 1979 - Elsevier
Abstract For economies with a large number of small firms, price induced changes in supply
are decomposed into substitution and entry effects. Marginal firms (those earning zero profit)
play a significant role in the determination of the slope of aggregate supply.

We examine a three-stage game in which duopolists face a random-demand intercept. Firms
first choose capacities, then decide whether to commit to share the private information they
will receive about the intercept. After the private information is observed, firms choose ...
