The profound changes to the world economy since the late twentieth century have been characterised by a growth in the number and size of transnational corporations. In this context, there is now increasing evidence of unprecedented reversals in health indicators among populations around the world. Research in this area has focused on documenting the global health impacts arising from the economic activity of corporations. The challenge for public health researchers is to understand the ways in which corporations are regulated by, and participate in global health governance and implications for health and well-being across the globe. This book is an introductory guide to conducting research on the role of corporations in global health governance from a range of disciplinary perspectives and gives an overview of different approaches, methodologies and data sources.
