2 Imperfect competition (2022)
Two companies, Thomas Inc and Edison Inc, are the only producers of electrical vehicles. The demand for
electrical vehicles is given by P=200-2gr-2gr. where qr is the quantity Thomas Inc produces and qeis the
quantity Edison Inc. produces. Both Thomas Inc and Edison Inc produce electrical vehicles at a constant
marginal and average cost of $20 per vehicle.
2.0p a
Find the total quantity of electrical vehicles produced in the Cournot equilibrium!
2.0p b Suppose that (for this subquestion only) the (marginal and average) cost per vehicle changes to $50. How
does this affect total quantity and price in Cournot equilibrium? For both total quantity and price, state
whether it goes up, down, or stays the same (no further explanations are required).
The total quantity produced
and the price
2.0p c Suppose that (for this subquestion only) a third company enters the market for electrical vehicles and
competes with Edison Inc and Thomas Inc. This company has exactly the same cost of production as
Thomas Inc and Edison Inc and consumers perceive its electrical vehicles as identical. How does this entry
affect total quantity and price in a Cournot equilibrium? For both total quantity and price, state whether it
goes up, down, or stays the same (no further explanations are required).
Following the entry of a third country, total quantity produced
and the price
2.0p d Suppose that (for this subquestion only) the nature of competition changes to a Stackelberg competition
where Thomas Inc first announces its production targets publicly. Assume for this subsection that the
reaction function of Edison Inc is qe=45-0.5g7. Determine Thomas Inc's output in the Stackelberg
equilibrium, still assuming that firms compete by setting quantities!
