Bookmakers are good at forecasting everything from horse races to elections. As was pointed out to me by a punter 50 years ago, the bookie doesn't need a crystal ball,he can simply monitor the flow of the money and change the odds accordingly, or lay off bets with other bookies to "balance the books". This balancing usually leaves him with a marketmaker's spread of profit on the conflicting bets.
The same principle applies in financial futures markets. Very complex issues are judged in those markets,such as the future trends in interest rates,currencies and commodities. The forecasts at any given time represent the consensus of the market players' judgements. One group of players is particularly important-those whose trading activity dominates the price movements in a recent time period, which could be measured in days,weeks or months. Those traders are usually the best informed,simply because they are speculating the largest sums.
Turning to nuclear power's risk and economics, governments shouldn't arbitrarily decide if nuclear power
is good or bad but let the marketplace assume the risks. They should invite large,well financed private consortia,not unaccountable state monopolies, to bid on nuclear power plant construction and operation. A condition of operation should require full insurance against potential environmental damage, costs of remediation and assumption of all
costs for waste disposal and safe monitoring of it in perpetuity. Let the insurance actuaries figure out the costs of the insurance.
If there are no takers, then governments would have to offer subsidies to the extent that reducing carbon emissions are worth it. If there are still no takers, then governments should forget about nuclear power until another
generation of more efficient nuclear power plants comes along.
