Characteristics of Consumer‐Preferred Labeling Policies: Experimental Evidence from Price and Environmental Disclosure for Deregulated Electricity Services

This study gauges how different information disclosure policies impact consumer understanding, performance, and satisfaction during the choice of a deregulated electricity supplier, and it explores how the market share of each firm responds to different policies in a hypothetical market. Compulsory disclosure of detailed price and environmental attribute information yields high consumer satisfaction and minimizes most types of information processing errors. The implications for disclosure policy and firm‐level market share are discussed.
