Proportional representation electoral systems allocate seats in the legislature based on the proportion of votes each party receives. This means that parties that receive a significant number of votes are likely to win seats in the legislature, even if they do not win a majority of votes. This can lead to a more representative government that reflects the diversity of views in society.

Majoritarian electoral systems tend to produce governments with a clear majority in the legislature. This can make it easier for the government to pass legislation and implement its policies. However, majoritarian systems can also lead to governments that are less representative of the entire population.

Mixed-member proportional electoral systems combine elements of both majoritarian and proportional representation systems. This can help to produce governments that are both representative and stable. Mixed-member proportional systems can also help to promote social cohesion by encouraging parties to cooperate with each other in order to form governments.

Majoritarian systems can also lead to political polarization, as parties become more entrenched in their positions in order to win elections.
