Testing legislator responsiveness to citizens and firms in single-party regimes: A field experiment in the vietnamese national assembly

Abstract

We investigate whether communicating constituents’ preferences to legislators increases the responsiveness of delegates to the Vietnamese National Assembly (VNA). Using a randomized control trial, we assign legislators to three groups: (1) those briefed on the opinions of their provincial citizenry, (2) those presented with the preferences of local firms, and (3) those receiving only information on the Communist Party’s objectives. Because voting data are not public, we collect data on a range of other potentially responsive behaviors during the 2018 session. These include answers to a VNA Library survey about debate readiness; whether delegates spoke in group caucuses, query sessions, and floor debates; and the content of those speeches. We find consistent evidence that citizen-treated delegates were more responsive, via debate preparation and the decision to speak, than control delegates; evidence from speech content is mixed.
