Conserving Spatially Explicit Benefits in Ecosystem Service Markets: Experimental Tests of Network Bonuses and Spatial Targeting
通过实验室和实地实验，检验了反向拍卖中网络奖金和空间定位两种机制对实现最优地块连续性的效果，发现单独使用空间定位能改善环境和社会福利，而单独使用网络奖金效果更差，两者结合则能减少福利损失。
Conserving contiguous areas often enhances environmental benefits. However, most conservation efforts are incentive‐based and voluntary, and neither reward landowners for contiguity nor do they select based on contiguity. Thus, achieving optimal contiguity of conserved parcels is unlikely. Using lab and artefactual field experiments, this paper evaluates two mechanisms in the context of reverse auctions for achieving optimal contiguity: network bonuses and spatial targeting. Results suggest that spatial targeting alone improves the aggregate environmental and social welfare outcomes, while network bonuses alone result in worse outcomes. The interaction of the bonus effect and the targeting effect is positive. If a program was already using a competitive auction environment with bonuses, adding spatial targeting could reduce welfare loss.
