This introduction summarizes the main contributions of this special issue titled “Quiet Politics and the Power of Business: New Perspectives in an Era of Noisy Politics.” The four articles in the issue use and extend Culpepper’s influential concept of “quiet politics” according to which business is able to shape policies and regulations when issues are of low salience to the public and politicians. The issue takes Culpepper’s analysis further in ways that respond to the rise of noisy politics over the last few years, often associated with new strident forms of left- and right-wing populism. Three contributions are made. First, the articles show that salience is not an inherent property of a policy area but is socially constructed. Second, a variety of strategies are described that business uses when trying to keep politics quiet. Third, strategies are affected by the structure of business, which varies across types of capitalism. Future research can use these insights to extend our understanding of the limits, strategies, and dynamics of quiet politics across political economies.
