Last year, I said that the BetFair prediction markets on global warming would fail.
I said:
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.
