Abstract Pro-environmental behaviour (PEB) is known to reflect people's social preferences, time preferences and risk preferences. Previous research has tended to consider these in isolation, which means they may proxy for omitted ones, leading to biased estimates. Moreover, it has not considered ambiguity preferences, which for some PEBs is conceptually more relevant than risk preferences. Using a survey module from the Global Preference Survey (GPS), we investigate the role of a large range of preferences for PEB in a sample of 900 middle class households in Lima, Peru. The PEBs we consider are habitually saving energy, avoiding the use of plastics, and limiting expenditures on electricity. We find that social preferences matter mainly for saving-energy behaviour; time, risk and ambiguity preferences matter mainly for the consumption of plastics; and time and ambiguity preferences matter for expenditures on electricity. The insight that particular preferences matter for particular PEBs has important policy implications.

秘鲁城市中产阶级家庭环保行为偏好的作用

摘要 众所周知，亲环境行为（PEB）反映了人们的社会偏好、时间偏好和风险偏好。以前的研究倾向于孤立地考虑这些，这意味着它们可能代表遗漏的那些，导致估计有偏差。此外，它没有考虑模糊偏好，对于一些 PEB 来说，它在概念上比风险偏好更相关。使用全球偏好调查 (GPS) 中的调查模块，我们在秘鲁利马的 900 个中产阶级家庭样本中调查了大范围的 PEB 偏好的作用。我们考虑的 PEB 习惯性地节约能源，避免使用塑料，并限制电力支出。我们发现社会偏好主要影响节能行为；时间，风险和模糊偏好主要与塑料消费有关；时间和模糊偏好对电力支出很重要。特定偏好对特定 PEB 很重要的见解具有重要的政策含义。
