Final answer:
In the presented game theory scenario, the optimal strategy for both corn growers is to cooperate and lower output, thus increasing their earnings. The analysis is based on the strategic thinking within the framework of the Prisoner's Dilemma.
Step-by-step explanation:
The scenario presented involves a strategic interaction between two corn growers, Mary and Raj, which can be analyzed using game theory, specifically the concept of the Prisoner's Dilemma. The best choice for Raj, assuming that Mary will cooperate, is to also cooperate and lower output, as this will result in both of them earning $150. If Mary believes that Raj will cheat, then her best response is to work independently to ensure she earns $100 instead of risking earning $0. The Prisoner's Dilemma outcome is that each player has an incentive to cheat regardless of the other's action, often leading to both players cheating and ending up with a lower payoff ($100 each) than if they had cooperated ($150 each). However, if they could ensure cooperation, their preferred choice would be to both cooperate and lower output to earn the higher amount.
