a. Show the output, price and profits of a monopoly in a well-labeled diagram.
b. Suppose the government imposes a lump-sum tax of $200,000 on this monopoly in (a). In words, explain whether this will affect your answers to (a).
a) Q is quantity produced
OP is the price charged
equilibrium is determined where MR= MC at point E and price is determined by AR curve at this output level Q
profits will be area below price line and abova the avarage cost which isequal to OM = QN at level of output Q
profits=PRNM
b) when the government imposes a lump-sum tax of $200,000 on this monopoly
fixed cost of this firm will increase by $200,000 and AC will shift upward but not parallely as ouput increases change in AC due to this lumpsum tax goes on decreasing because its Fixed Cost
new AC = old AC+ FC/q
as q, quantity increases FC/q will decrease
MC will not get affected as it is fixed cost whereas MC is affected by Variable cost
after this
Q and P will remain at same level but profits will decrease due to increase AC
profits will decrease to shaded region which is samller than area PRNM
