Abstract:
This paper explores the relationship between special-interest groups and economic growth, using newly assembled data on the number of groups observed across countries. In a sample of 86 countries at two points in time (for a total of 169 observations), we ¯nd support for Mancur Olson's theory that interest group activity reduces economic growth. We also ¯nd evidence that interest groups are negatively associated with both channels to growth - capital stock growth and productivity growth.
