Abstract:
This study investigates how economic scarcity influences third-party punishment, a costly and non-self-interested behavior that plays a critical role in maintaining social norms and cooperation. In real-world contexts, individuals often operate under resource constraints that may systematically alter their cost-benefit calculations; however, it remains unclear whether and how scarcity affects the willingness to punish unfairness. Across two experiments, we examined whether scarcity reduces individuals' propensity to engage in third-party punishment. Experiment 1, involving 70 participants, showed that individuals under scarcity allocated significantly fewer resources to sanction unfair dictators than those in a control condition. Experiment 2, with 41 participants, replicated this design across two time points separated by 2 months. The results further confirmed the suppressing effect of scarcity on punishment and demonstrated a similar pattern of results across time points. These findings offer important theoretical and practical implications for promoting cooperation and effective norm enforcement under resource-limited conditions.

Punishment
Punishment can be positive or negative. Positive punishment involves adding an undesirable stimulus, such as scolding, to decrease a behavior. Negative punishment involves removing a desirable stimulus, such as taking away a favorite toy, to decrease behavior.
Timing and Consequences on Behavior
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant factor...
