a) Suppose Windhoek Municipality, a monopolist in water supply can segregates the water consumer into two market groups based on their ability to pay. The inverse demand curves for the two segregated markets are given by: Q 1
​
=120−P 1
​
and Q 2
​
=120−2P 2
​
. Its total cost for both markets is given as TC=10000+4Q i) Find the price equilibrium quantity and price charge in each of the two markets and total profits under the two price policy of third degree price discrimination ii) Calculate the deadweight losses/excess burden incurred in each market [2 marks] ​
[4 marks] iii) If the Namibian government make price discrimination illegal, find the output, price charged and deadweight loss under a single price policy iv) Find the output, price charged, profit and deadweight loss, if Windhoek Municipality provide water under perfect competition [2 marks] v) What economic implication can be deduced from your answers in ai) to iv)?
