Also some info there on the 2000 problem although they overstate the problem for PC's. I mark 1987 as the water shed year. The interesting thing is that this collapse has been in slow motion, unlike the 1930's. Since there is still time before the deflation ends, it would be normal to expect a collapse in oil prices - look at what gold is doing.
Oil is a proxy for the monetary base of the world.
This will put considerable pressure on the price structure of all goods. Inflation hides errors in judgement while deflation exagerates them. Using the long wave allows a look at both the short and long term effect of a sharp break in oil prices. Long term the decline of the monetary base and thus deflation will force a selectivity between goods. Since most manufacturers resist a decline in price at all costs increased rates of deflation will produce a stagnation and surplus in consumer goods.
