This paper explores the relationship between special-interest groups and volatility of GDP growth. In an unbalanced panel of 108 countries, we find a significant negative relationship between the number of interest groups in a country and the volatility of GDP growth.

This paper empirically explores the relationship between special-interest groups and volatility, with focus on the interplay between groups and democracy and on the impact of groups on policy volatility. We find that countries with more interest groups are characterized by less policy...

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...

We investigate the relationship between interest group activity and investment by analyzing an unbalanced panel of observations on 126 countries over three time periods. We find that the number of interest groups in a nation is negatively related to investment, consistent with a sclerotic effect...
