Altruism, Valuation and Global Change

这是一项关于利他主义和利己主义在塑造对环境的行为方面的作用的研究。更好地理解这种关系很重要，因为气候变化、臭氧消耗和生物多样性的丧失都涉及在很大程度上是公共产品的资源。因此，大多数提出的缓解全球环境变化的机制都涉及公共政策，这些政策要求在提供环境质量时权衡个人和集体的成本和利益。结构方程模型将用于分析通过电话采访500人收集的数据。这项研究将提供公众对温室气体变暖和物种丧失等关键全球变化问题看法的基线信息。这项研究还将有助于我们理解，为旨在减少全球变暖和物种损失的公共政策买单的意愿如何取决于环境态度和价值观。

This is a study of the role of altruism and self interest in shaping behavior towards the environment. A better understanding of this relationship is important because climate change, ozone depletion and loss of biodiversity all involve resources that are in large part public goods. For this reason, most mechanisms proposed to mitigate global environmental change involve public policies that require a tradeoff between individual and collective costs and benefits in the provision of environmental quality. Structural equation models will be used to analyze data collected in phone interviews with 500 individuals. This study will provide baseline information on public views on key global change issues, such as greenhouse warming and species loss. The study will also contribute to our understanding of how willingness to pay for public policies aimed at reducing global warming and speciesloss depend on environmental attitudes and values.
