Strength in Numbers

“This book makes a bold and startling claim: diffuse interests, rather than concentrated interests, dominate the making of public policy in the advanced democracies.”—Pepper D. Culpepper, European University Institute

“Trumbull attacks head on the Olson tradition of diffuse versus concentrated interests, which suggests that the concentrated will always defeat the diffuse. He argues that the diffuse often wins—at least far more often than the standard Chicago collective action theory suggests.”—Peter Gourevitch, University of California, San Diego

“In Strength in Numbers, Gunnar Trumbull advances a powerful critique and alternative to the dominant understanding of interest-group politics developed by Mancur Olson.”—Jonah Levy, University of California, Berkeley
