Concept and examples
Meguid (2005) defined niche parties as parties that raise new issues outside the left–right divide and concentrate on them. As post-materialist values grew from the 1970s, green parties emerged, alongside anti-immigration radical right and regionalist parties. They contrast with catch-all parties.
Mainstream strategies
Meguid (2005; 2008) argued niche success depends on mainstream responses: dismissive, accommodative (co-opting the position) or adversarial (opposing it). Adversarial strategies can strengthen the niche party's issue ownership. The debate links to cartel parties.
Behaviour and measurement
Adams and colleagues (2006) showed niche parties, unlike mainstream ones, lose votes when they moderate, and Ezrow (2008) found votes can rise with distance from the average voter. Wagner (2012) defined niche parties by low emphasis on economics and concentration on few issues; Meyer and Miller (2015) proposed a relative measure, and Bischof (2017) a market-share concept.
