information about the role assumed by the other.

Oligopole represents the situation of a market where there is a small number of bidders (at least two)
of a non-substitutable good and a sufficiently large number of consumers. Oligopole composed of two
producers is called duopoly.
Considering two competing companies A and B that produce the same normal good, we propose to
analyze each of them in response to the activity of the other firm.
Each of them when determining their production level and selling price will consider the production
and price of the other. If one of the two companies first establishes the price or the quantity produced,
the other one adjusting for it, then it will be called the price leader, respectively the production leader,
the second firm called the price satellite or the production satellite.
2. The Analysis
Companies A and B have incomplete information about each other. They will consider the other firm
as a production leader or satellite.
Consider for the beginning that the company A is considered to be leader of quantity. If it produces QA
good units, then B, considered by A as a satellite, will adjust its output after A producing QB=f(QA)
units of good. The sales price is dependent on the total quantity of products placed on the market. So
let's say: p=p(QA+QB) the price per unit of product.
