 This paper reviews the literature on corporate power and proposes a new framework for understanding the commercial determinants of health, C2H. It examines the role of corporate power in influencing population health through the lens of various corporate power theories. These include the structural power of large multinational corporations, the ideological power of corporate interests, and the material power of economic resources. The authors argue that public health professionals should consider the role of corporate power when analyzing the C2H. This article was authored by Benjamin Wood, Philip Baker, and Gary Sacks.
