Exercise | Q 5 | Page 101

If the monopolist firm of Exercise 3, was a public sector firm. The government set a rule for its manager to accept the government fixed price as given (i.e. to be a price taker and therefore behave as a firm in a perfectly competitive market). And the government decide to set the price so that demand and supply in the market are equal. What would be the equilibrium price, quantity and profit in this case?
