How do business firms decide on their strategies for political advocacy? What agents do they use to influence the business and governmental environments? Should a corporation use an outside agent such as a trade association or rely on an in-house public affairs manager? This book represents the first-ever comprehensive overview of the burgeoning phenomenon of corporate political agency. Beginning with the basic theoretical concerns of understanding the competitive nature of the democratic system, this collection moves on to the practical considerations of whether the various chosen forms of public affairs activity actually work as intended.
