How Weakly Institutionalized Parties Monitor Brokers in Developing Democracies: Evidence from Postconflict Liberia

Political parties in sub‐Saharan Africa's developing democracies are often considered to lack sufficiently sophisticated machines to monitor and incentivize their political brokers. We challenge this view by arguing that the decentralized pyramidal structure of their machines allows them to engage in broker monitoring and incentivizing to mobilize voters, which ultimately improves their electoral performance. This capacity is concentrated (a) among incumbent parties with greater access to resources and (b) where the scope for turnout buying is higher due to the higher costs of voting. Using postwar Liberia to test our argument, we combine rich administrative data with exogenous variation in parties' ability to monitor their brokers. We show that brokers mobilize voters en masse to signal effort, that increased monitoring ability improves the incumbent party's electoral performance, and that this is particularly so in precincts in which voters must travel farther to vote and thus turnout buying opportunities are greater
