　　报告主题：A theory of multi-tier ecolabel competition

　　摘要：Certification schemes for credence goods like environmental attributes continue to grow in popularity. The literature has focused on labels that are binary in structure, but we present a theory in which the choice between multi-tier and binary labels is made strategically by competing label sponsors. We show that allowing for multi-tier labels can qualitatively change the nature of equilibria in ecolabel competition. Our theory explains how standard-setting organizations choose between these two forms, and compares the differing incentives of industry trade associations and non-governmental organizations (NGOs) in setting standards. For either type of organization in autarky, multi-tier labels are more attractive when the number of producers with a low cost of quality is small and the cost gap between low-cost and high-cost firms is large. When the two types of organization compete using binary ecolabels, multiple equilibria may exist and the NGO may offer either the more ambitious label or the basic label; competition may provide either more or less environmental protection depending upon industry structure. When competition occurs using multi-tier labels, however, there exists a unique equilibrium pair of standards, and competition always provides less environmental protection than would the NGO in autarky.
