Information aggegration

Combinatorial markets

What are they?


How do they help?

  • discrete time helps people who can’t be awake 24/7 updating immediately on everything
  • need to balance
    • using markets to gain insight
    • keeping forecasters from just copying the median (this can either be done by discretising time or real money markets where people without new information (=an edge) just don’t trade)
