Farmers' Perceived Costs of Wetlands: Effects of Wetland Size, Hydration, and Dispersion
通过调查农民，发现湿地分散会增加耕作不便成本，而水合频率的影响非线性且不规则；农民对环保的态度和人口特征也影响感知成本，提示整合分散湿地可能同时惠及农民和增加湿地面积。
Abstract We survey landowners to investigate the costs associated with the presence of permanent or seasonal wetland areas in cropland. We find, as predicted by our conceptual model, that dispersion of wetland areas imposes substantial inconvenience costs for producers but that costs respond nonlinearly and irregularly to changes in the frequency of hydration. Producer attitudes toward conservation and environmental regulation have a significant impact on perceived costs, as do some demographic attributes. The analysis suggests that incentives to aggregate dispersed wetlands into larger contiguous areas could benefit landowners and at the same time provide a net increase in wetland area.
