Question
5. The demand for cement is given by P=40-8Q, where P is the unit price in kroner
(SEK) and Q is quantity demanded (measured as tons of cement per day). A cement industry
characterized by perfect competition has a short-run supply function given by P=4+Q.
(Note that 4+ Q is the industry's marginal cost)
5a
Calculate price and quantity traded in equilibrium.
5b
Calculate the industry's producer surplus and consumer surplus in equilibrium.
Illustrate the surpluses and the equilibrium from subtask 5a in a figure.
5c
Now suppose that the manufacture of cement creates environmentally hazardous
waste that is discharged into the immediate area and causes other actors costs (denoted by
MCE). These amount to
SEK 1,8 per ton of cement produced (so MCE= 1,8). Calculate it socially
optimal equilibrium.
5d
Calculate the size of the unit tax that when paid by the producers leads
until the socially optimal level of production is reached.
