Question
What would be the shape of the demand curve so that the total revenue curve is
(a) a positively sloped straight line passing through the origin?
(b) a horizontal line?
Solution
(a) If the total revenue curve is a positively sloped straight line passing through the origin, then the slope of the demand curve will be a horizontal line parallel to the x-axis.
(b) If the total revenue curve is a horizontal line, then the demand curve will be downward sloping.

List the three different ways in which oligopoly firms may behave.
If duopoly behaviour is one that is described by Cournot, the market demand curve is given by the equation q = 200 − 4p and both the firms have zero costs, find the quantity supplied by each firm in equilibrium and the equilibrium market price.
What is meant by prices being rigid? How can oligopoly behaviour lead to such an outcome?
