Last year, I said that the BetFair prediction markets on global warming would fail.
My prediction is that the first two BetFair Global Warming prediction markets (HSBC Investable Climate Change Index and ECX CFI Futures Contract) will fail miserably.
They failed, indeed. Remain only those two prediction markets, with ultra light volumes: Highest and Lowest UK Temperature.
As for the InTrade prediction markets on climate change (USA agrees before end of 2009 to reduce CO2 emissions by 10% or more by year 2025), liquidity is more than thin.
Now, ask yourself:
- If BetFair and InTrade (which are for-profit prediction exchanges) encounter difficulties with those “-socially valuable prediction markets”-, why would not-for-profit prediction exchanges (like the Iowa Electronic Markets) be more successful at it?
- Don’-t you think that the American Enterprise Institute’-s proposals (which would outlaw the for-profit prediction exchanges) are out of whack? I do. Let’-s do something.
