Variable: Cummulative Party System Innovation of a second election in a year

QoG Code: (psi_cpsi2)


Dataset: New Parties and Party System Innovation in Western Europe

Description:

Cumulative Party System Innovation: sum of the vote share received by non-founder parties in each election. A party is considered as a founder if it has received at least 1% of the national vote share in at least one of the first two post-WWII elections (or, in the case of Greece, Portugal and Spain, the first two democratic elections). Otherwise, the party is counted as a non-founder. The rationale behind this choice is that we look at the first two post-WWII or post-authoritarian elections and make a dichotomous distinction between relevant parties that formed the system (those who received more than 1% of the votes) and parties that emerged later or were only marginal actors (those below 1%) at that time. This variable (psi_cpsi2) refers to a second election held on the same year as an election reported on psi_cpsi1.
