Two firms, VolgaBus and GMB, are competing to sell 100 buses to MetroTravel, a cityowned

bus company. They each submit a sealed bid to get the contract, with the contract

going to the lowest bid. Each firm has the option of submitting a low-price bid of $15 000

per bus, or a high-price bid of $20 000 per bus. In the event of a tie, the city will buy 50

buses from each firm.

Expert's answer

Two firms, VolgaBus and GMB, are competing to sell 100 buses to MetroTravel.

Each firm has the option of submitting a low-price bid of $15 000 per bus, or a high-price bid of $20 000 per bus. In the event of a tie, the city will buy 50 buses from each firm.

a. If one firm win the contract with low-price bid, it will receive 100*$15,000 = $1,500,000, another firm will receive $0.

In the event of a tie at low-price bid each firm will receive 50*$15,000 = $750,000.

In the event of a tie at high-price bid each firm will receive 50*$20,000 = $1,000,000.

So, a payoff matrix for this simultaneous game is:

VolgaBus\GMB Low-price bid High-price bid

Low-price bid $750,000\$750,000 $1,500,000\$0

High-price bid $0\$1,500,000 $1,000,000\$1,000,000

b. Based on our matrix from part a., the Nash equilibrium will be a tie at low-price bid, so each firm will receive 50*$15,000 = $750,000, because both firms will choose a low-price strategy to win a contract.

Each firm has the option of submitting a low-price bid of $15 000 per bus, or a high-price bid of $20 000 per bus. In the event of a tie, the city will buy 50 buses from each firm.

a. If one firm win the contract with low-price bid, it will receive 100*$15,000 = $1,500,000, another firm will receive $0.

In the event of a tie at low-price bid each firm will receive 50*$15,000 = $750,000.

In the event of a tie at high-price bid each firm will receive 50*$20,000 = $1,000,000.

So, a payoff matrix for this simultaneous game is:

VolgaBus\GMB Low-price bid High-price bid

Low-price bid $750,000\$750,000 $1,500,000\$0

High-price bid $0\$1,500,000 $1,000,000\$1,000,000

b. Based on our matrix from part a., the Nash equilibrium will be a tie at low-price bid, so each firm will receive 50*$15,000 = $750,000, because both firms will choose a low-price strategy to win a contract.
