Estimating the Supply of Conservation Goods in Britain: A Comparison of the Financial Efficiency of Two Policy Instruments
比较英国环境敏感区协议与特殊科学兴趣点谈判管理协议在获取公共保护性产品上的财务效率，发现SSSI比ESA更具成本效益。
Rapid uptake of agreements in Environmentally Sensitive Areas (ESAs), compared with negotiated management agreements on Sites of Special Scientific Interest (SSSI), has lead to renewed interest in obtaining public conservation goods through agreements in the U.K. Economic comparisons between these two instruments are made using a simple supply model. The paper reviews the legal/administrative basis for management agreements, states relevant theory, and compares these two means of securing conservation goods. Conclusions regarding the difference in public expenditure on these mechanisms are established and information on transactions costs presented. The conclusion is that SSSI are more cost-effective than ESAs.
