Distributive Politics, Representation, and Redistricting

We develop a theory of distributive competition under redistricting that explains both electoral outcomes and the equilibrium allocation of policy benefits by endogenizing voter pivotality. In a multi-district model with primaries, general elections, and group-targeted transfers, districting shapes political influence through two channels: a selection channel for descriptive representation (who wins office) and a competition channel for substantive representation (who receives policy benefits). District composition alters candidate matchups, shifting voter responsiveness and political leverage, and each channel alone yields distinct predictions about whether packing or cracking voters is optimal. For minority voters, the welfare effects of districting depend on electoral leverage, preferences over descriptive versus partisan representation, primary rules, and competitiveness. The channels align on packing when minorities are electorally weak and value descriptive representation, and align on cracking when minorities are electorally pivotal and prioritize partisan outcomes. When the channels diverge, or when endogenous feedback reshapes electoral leverage, minority welfare can be nonmonotonic in voter concentration. Our results identify when majority-minority districts enhance minority welfare and when dispersion strengthens political influence.

Delegation and Lobbying

This chapter examines the link between delegation and lobbying, two themes central to political economy. Delegation models explore how legislatures manage uncertainty and control bureaucratic agents, while lobbying models analyze how organized interests influence policy through contributions, information, and advocacy. We review the growing body of research that integrates these literatures, showing how the prospect of lobbying affects legislative incentives to delegate and how the structure of delegated authority shapes lobbying strategies. We highlight common-agency frameworks that capture the recursive relationship between delegation and lobbying and empirical studies documenting how venue choice, information provision, and interest group mobilization mediate delegation outcomes. We also review applications to agency oversight and fiscal policy. Finally, we present a model of regulatory rule-making that embeds lobbying directly into the delegation decision, offering predictions for both theory and empirical analysis.
