Trust, Happiness, and Pro-social Behavior
结合大规模调查和实证策略，研究发现最大化主观幸福感的信任水平高于最大化收入的水平，且更高信任与更多合作及亲社会行为（如应对气候变化）相关，支持了亲社会行为的“暖光”理论。
Abstract This paper combines several large-scale surveys and empirical strategies to shed new light on the determinants of cooperative behavior. We provide evidence indicating that the level of trust maximizing subjective well-being tends to be above the income maximizing level. Higher trust is also linked to more cooperative and pro-social behaviors, including the private provision of global public goods such as climate change mitigation. Consistent with “warm glow” theories of pro-social behavior, our results indicate that individuals may enjoy being more cooperative than what would lead them to maximize income, which can be reflected in higher levels of subjective well-being.
