Legislative responses to social changes signify how representative democracy works. Yet research is still needed to find out whether and how representatives in new democratic countries address the constituents’ interests and demands. We revisit the 18th National Assembly in Korea (2008–12) to examine legislative activities surrounding the issue of economic inequality. To understand how lawmakers in the new democracy like Korea respond to the demands of redistributive policies, we turn to representatives’ co-sponsorship behaviour. We find that Korean lawmakers do respond to constituents’ preferences. More specifically, Korean lawmakers representing conservative districts tend to care less about economic inequality than other representatives while controlling their partisanship. This study fleshes out the link between the represented and the representatives in a new democracy where party discipline at the expense of constituency connection has long dominated legislative politics.
