Comments: The Relationship Between Pollution Control Record and Financial Indicators Revisited.
评论了一项关于污染指数与股票投资决策中财务指标关系的研究，指出其证据基于虚假关系，并提出了基于统计关系的模型构建思路。
Abstract The article comments on a study about the relationship of pollution indices to financial indicators in stock investment decisions. The five financial indicators used were profitability, size, total risk, systematic risk, and price/earnings ratio. The study showed that the evidence presented rests on spurious relationships created through one or more intervening variables. An outline on constructing a model, based upon statistical relationships, is also presented. The relationship among size, pollution control and other financial characteristics is illustrated.
