Real-state market

When real-state price is falling many investors/buyers tend to wait until it falls further. This hurts the economy. As a result the market falls further because some people need to sell at lower price.
Why not, create a new deal that you sell at today's price but contract with the buyer that in a year or two if the house price index has fallen by a certain percentage (you keep that in an escrow but collect interest) then you refund that % to the buyer. There is no point in waiting. The market moves in a self organized way (not by government intervention) and the market stops falling and you may not have to refund anything. This could be a new type of contract which creates possibility of win-win situation.

Fail over

There is a joke (by De Bono) about the airline pilot who apologized to the passengers for having to shut down one engine. He explained that it meant they would arrive two hours late into New York. A second engine failed and he explained that they would be four hours late. Then a third engine failed. At this point the co-pilot leaned across to him and said:” I hope to goodness the last engine doesn't fail or we shall be up here all night!"
