In the right place, at the right time: opportunity structures and candidates’ chances of getting elected for the first time

The foundational principle of representative democracy is that legislative elites can be replaced in elections. Yet, first-time parliamentary entries have received little attention. We present the first systematic attempt to examine the conditions of first-time parliamentary entry in multimember district PR systems. We introduce an overlooked explanatory factor, candidates' short-term opportunity structure. While controlling for personal vote-earning attributes (PVEAs), we examine how competitive context shapes newcomers' chances in a pure OLPR system where party elites cannot skew competition between candidates. Our register-based analysis of candidacies in seven Finnish parliamentary elections (1995-2019, n = 7548) shows that while personal qualities enhance candidates' chances, first-time entry is restricted by the competitive context, especially the decisions of incumbent MPs. The strong impact of exceptional PVEAs suggests that other "big fish" candidates may also shape competitive contexts. Overall, the study indicates that electoral competition can be rather restricted even in the most competitive electoral systems.
