Figure 1
Median price of new houses in the West of the United States.
The two numbers above the
peaks give the amplitude of the peak (the ratio of peak price to initial price) and the amplitude of the fall in the
down-going phase (ratio of trough price to peak price). The notation 1.7+ shows that the current peak is still
in its up-going phase and will have an amplitude larger than 1.7. The whole curve has been smoothed using a
three-year centred moving average. Source: US. Bureau of Census.
