The Economic Value of Biodiversity Preservation
研究了在生物多样性价值不确定甚至模糊的情况下，投资者和政策制定者如何做出保护决策，发现模糊厌恶会加速低价值物种灭绝，建议通过稳定透明的政策环境降低模糊厌恶。
Abstract We study the decision to preserve diverse species when the value of biodiversity is uncertain, or even affected by ambiguity. Optimal decisions are derived both from the perspective of the producer/investor and the policy regulator (ecosystem planner). We find that while calculated risk creates a scope for biodiversity preservation, the presence of ambiguity aversion reduces it, thus accelerating the extinction of species with lower value. Our results suggest that effective conservation strategies would involve a reduction of ambiguity aversion by creating a stable and transparent policy environment. Furthermore, they may involve a two tier strategy, with one tier addressing output targets and the other conservation targets.
