Stiglitz: the west must adjust its economy to meet the needs of war.

One adjustment is to impose a windfall profits tax.

He advocates a nonlinear price scheme for electricity. The first 90% of the electricity you used last year, you can buy at last year's price, the next 20% you can by at 1.5 times that price, and any more beyond that you would buy at a price based on current conditions.

He also advocates an end to paying farmers to grow less food. (I think this would have to be accompanied by rules to give wildlife a home in farms.)
