This paper develops the social screening method used by Milevsky et al (2005).

According to Milevsky, "in a study funded by the Canadian Social Sciences and Humanities Research Council, Thomson and Wheeler (2004) hypothesize that of all potential measures of corporate social performance, those that measure labour and employment practices are like to be especially salient to firm performance and risk minimization. This conclusion follows from an examination of a large number of sources relating firm performance and the generation of competitive advantage through the leveraging of intangible assets such as human, intellectual, and social capital (see, for example Dess & Picken (1999); Nahapiet & Ghoshal (1998))."
