Contestation and participation
Dahl (1971) classified regimes as closed hegemonies, competitive oligarchies, inclusive hegemonies or polyarchies, building on pluralism.
Institutional guarantees
Dahl (1956, 1989) listed elected officials, free and fair elections, inclusive suffrage, the right to run, free expression, alternative information and associational autonomy, a minimal standard for democratic principles that separates polyarchy from competitive authoritarianism.
Measurement
Coppedge and Reinicke (1990) built a polyarchy scale, Munck and Verkuilen (2002) evaluated indices, Coppedge and colleagues (2008) confirmed two dimensions and Teorell and colleagues (2019) presented V-Dem's index, used in backsliding research.
