Gender and party appear as the only two main variables explaining conflict and consensus in institutional politics. Contrary to what might be expected, the number of women in a parliament has an effect on the level of conflict in conducting politics. Similarly, the ideological nature of the party (leftist or conservative) has an effect in the level on conflict in parliaments in democratic systems. Using data coming from 17 regional parliaments, the authors present the interactions between consensus (and conflict) and different social and institutional factors.
