The two conflicting tendencies that a firm has in an oligopolistic industry are the incentive to

cooperate in a joint aggrement to maximize profit as well as the incentive to cheat to have increaseed share of the profit.

Explanation:

Since oligopolistic market has a joint decision making interdepency on each other to ensure that each firm in the industry has its own share of the market, there can only be conflicting behaviours amongst the firms to either make profits togtehr or make profit at the detriment of tthe other firms

work together in a collusive agreement that will maximize the profits for the supplying firms in the oligopolistic industry versus the temptation to cheat on that agreement in order to increase the company's profit.

Explanation:

A collusive agreement is a secret non competitive agreement made between competing firms in order to gain market advantage. Sometimes firms in an oligopolistic industry agree to not compete with each other, that leads to a collusive oligopoly.

The problem is that a cheater will always want more, and first they cheat on customers, but eventually they end up cheating their own collusive agreement.
