When do political parties prioritize labour? Issue attention between party competition and interest group power
This article analyses the conditions under which political parties spend attention to labour issues. This article compares the dominant partisan perspective, which proposes that attention to issues is shaped by party competition, to an interest group perspective, which proposes that strong interest groups, in particular when their power is institutionalized in corporatist systems, can force parties to spend attention to their issue. We use the Comparative Agenda Project data set of election manifestos to examine these patterns in seven West-European countries and corroborate our findings in the Comparative Manifesto Project data set for 25 countries. The evidence supports the interest group perspective over the partisan perspective. This shows that the study of party attention to issues should not isolate party competition from the influence of other political actors.
