Replication data for: Party System Nationalization and the Provision of Public Health Services

In this paper we examine consequences of party system nationalization. We argue that the degree to which party systems are nationalized should affect the provision of public benefits by governments. When political competition at the national level occurs between parties that represent specific sub-national constituencies, then the outcomes of policy debates and conflicts can lead to an undersupply of nationally-focused public services. We test our argument using data on DPT and measles immunization rates for 58 countries. We find that low party system nationalization is a barrier to improvements in these health indicators. Specifically, a substantial presence of regionalized parties hinders states’ convergence towards international heath standards.
