Explaining Cooperative Behavior

Evaluating Predictions of Economic Models

Two firms in the same market face a choice: they can either cooperate by setting a high price for their product, leading to a good shared profit, or one can undercut the other by setting a low price to capture the whole market, which is better for them individually but worse for the other firm. Match each contextual factor below with its most likely impact on the firms' decision to cooperate.

According to standard economic models that assume all individuals act solely out of self-interest, the frequent observation of cooperation in situations where defection would yield a higher individual payoff is an expected and predictable outcome.

Two competing coffee shops are located next to each other. Each shop has the choice to either set a high price for their coffee or a low price. If both set a high price, they both make a moderate profit. If one sets a low price while the other sets a high price, the low-price shop captures most of the market and makes a large profit, while the high-price shop makes a loss. If both set a low price, they engage in a price war and both make a very small profit. Economic models based on pure self-interest predict that both shops will set a low price. However, in reality, both shops are observed maintaining a high price. Which of the following provides the most plausible explanation for this cooperative outcome?

Altruism as a Solution to Social Dilemmas

Consider a strategic situation involving two individuals where mutual cooperation leads to a good outcome for both, but an individual can achieve an even better personal outcome by defecting while the other cooperates. If both defect, they both end up with a poor outcome. Economic models assuming pure self-interest predict that both individuals will defect. However, in reality, cooperation is often observed. How does the presence of altruism (a genuine concern for the welfare of others) explain this cooperative behavior?
