The Information Content of Advertising: A Meta-Analysis
对近60项使用Resnik和Stern方法测量广告信息含量的研究进行元分析，揭示信息水平的规范、研究方法的系统性差异来源，并指出需进一步研究的领域。
Abstract Abstract The amount of information contained in advertising is an important issue to scholars, critics, and users of advertising. Almost 60 studies have used a procedure introduced in 1977 by Resnik and Stern to measure the information content of advertising. The results, reported in a wide variety of outlets, are conflicting. Metaanalysis of that literature helps to (1) develop norms for information levels and research procedures, (2) reveal systematic sources of variation in reported information levels across studies, and (3) identify areas that have been examined in depth and call attention to other areas that warrant further research. Because study findings are found to depend on several method factors, controlling for the effects of those factors through the meta-analysis procedure helps to clarify how media type, country economic development, and product durability influence measured information levels.
