Abstract

Although the concept of corporate social responsibility is fundamentally multidimensional, most studies use composite scores to assess corporate social performance. How relevant are such composite scores? How the CSR dimensions are weighted? Should the weighting scheme be the same across sectors? This article proposes an original weighting scheme of CSR strengths and concerns, at the sector level, which is proportional to media and nongovernmental organizations scrutiny. The authors show that previous CSP assessments underweight environmental and corporate governance concerns. Moreover, findings suggest that firms that are exposed to the closest scrutiny are usually criticized on one single dimension: for instance, banks for bad corporate governance, and basic-resource firms for environmental damage. Composite scores based on equal weights hence misrepresent CSP and the difference in CSR between sectors.
