Representatives and districts

Why would any group want to have a decision-making body composed of representatives? The best answer is found in the “Anti-Federalist ideal” identified by Wood [1992]: if within-group benefits are highly correlated, a legislature composed of randomly chosen representatives that maximized its own well-being would maximize the well-being of the entire polity. This argument for representative government implies that the best districting schemes are the most segregated: within-district variance is minimized. Received: 9 June 1997/Accepted 28 December 1998
