Abstract

We investigate the impact of territorial fragmentation on political representation by applying Taagepera's cube root law to subnational governments. Our model reveals that the total number of local representatives is more elastic to changes in the number of jurisdictions (elasticity e = 2/3) than to variations in population size (e = 1/3), a relationship we refer to as the law of 2/3. As a result, political representation is amplified in fragmented areas. Empirical evidence from diverse datasets supports this new law.
