Rewards can be surpluses and taxes can be punishments.
Through price collusion, each firm would achieve higher profits.
When competing businesses agree to cooperate, such as by raising prices in order to increase profits, this is called collusion. Collusion is a strategy used by businesses to increase profits at the expense of customers and lowers market competition.
Lower consumer surplus, higher prices, and more profits for the colluding businesses are the results of collusion. It may enable oligopolists to exercise monopoly power and increase their group earnings. In an oligopoly, businesses have a strong incentive to work together.
Collusion may be a tactic used in times of unproductive economic circumstances to try and rescue the industry and save companies from going out of business, which would not be for the long-term benefit of consumers.
