Hundreds of studies explored and measured the financial returns related to social performance (Margolis and Walsh, 2003), with controversial results. Beyond research’s outcomes, we found into this stream of literature a lot of innovation about the integration and adaptation of tools and models of financial analysis with the study of statistical relationships. In this paper we investigate about the relationship between corporate social performance and corporate financial (and economic) performance, that uses multiple measures of financial and social performance and looks statistically at the movement of actual financial and social performance over time. We emphasize the worth of statistical analysis and its integration into traditional financial representations. Our findings show how ratio analysis and statistical cause-and-effect validation are not alternatives for developing the financial analysis of sustainability and the reporting. We show, through a constant testing and a double learning process, the critical relationship between the key factors of financial, economic and social performance.
