We study the relationship between parties’ candidate selection processes and
legislative productivity. Utilizing the legislation data of the 17th National
Assembly for which some of candidates were selected by the bottom-up
selection process, we try to shed some light on how candidate selection
methods affect what bills to propose, other party member’s countersignature,
and the possibility that a bill passes on the floor. Furthermore, we examine
how a legislator’s performance, especially the number of proposed bills and
passed bills influences his/her chance of reelection. Anchored on our empirical
analysis, we argue that it is desirable to adopt bottom-up candidate selection
in all the levels of elections, hold National Assembly election and local
elections in the same year, and revise campaign finance-related acts to
enhance the legislative productivity.
