Introduction to Social Choice

Published by Mario Oettler on

The core idea of social choice is:

Decisions of a group through aggregation of individual preferences to a collective decision.

Each member of a group has its own individual preferences. In order to come to a collective decision, it is necessary to aggregate them. For that purpose, different methods and designs exist:

  • Condorcet Method
  • Majority Vote
  • Borda Count
  • Coombs Method
  • Instant Run off
  • Coin-based voting
  • Quadratic voting
  • Rough Consensus
