Market Share Specification, Estimation, and Validation: Toward Reconciling Seemingly Divergent Views
解释了1984年JMR三篇关于市场份额设定、估计与验证的复制研究中看似矛盾的结果，指出差异可被解释，旨在调和不同观点。
In the May 1984 issue of JMR three articles describe replications and extensions of work reported by Naert and Weverbergh in the May 1981 issue of JMR. They address various problems of market share specification, estimation, and especially validation. A rough comparison of the research findings seems to indicate that no general conclusions can be drawn. However, several of the differences in findings can be explained. Providing these explanations is the main purpose of this article.
