Final answer:
Firm 1 would pay Firm 2 to cheat by producing a higher level of output.
Step-by-step explanation:
In the scenario of collusive output in a Cournot competition, if Firm 2 commits to the collusive output, it pays Firm 1 to cheat by producing a higher level of output.
In a collusive agreement, the firms cooperate to reduce output and keep prices high, mimicking a monopoly. However, one firm can benefit by producing more and gaining a larger share of the market.
By producing a higher level of output, Firm 1 can potentially attract more customers and earn higher profits, while Firm 2 adheres to the collusive output level.
