What is a bubble? • A bubble is defined as • “an upward price movement over an extended period of 15 to 40 months that then implodes.” and • “in the 20th Century most of the manias and bubbles have centered on real estate and stocks.” (Kindleberger and Aliber, 2005) • magnitude of change of the asset price exceeds 40%

  9. A study across 3 bubbles • Japan (The Lost Decade) in 1989, • Hong Kong (Asian Financial Crisis) in 1997, • The US (Subprime Crisis) in 2008. • Any common symptoms across the 3 bubbles, happened in 3 cities, in 3 decades, and of 3 different causes.

  12. The US Property Price Bubble Up from 32 to 294 (819%) from 1970 to 2007 (37-year), then plummeted in 2007/2008 …

  14. A unique cause of the Hong Kong Property Bubble? • Asian Financial Crisis (Currency) started in Thailand in July 1997, • but Hong Kong dollars is pegged to the US$, no currency risk, • the bubble burst was said to be a contagious effect of the whole region

  20. Why Cut Interest Rate?2 • cushion the effect of the strong currency : • 1980 - 1989 (JAP)

  24. Why haven’t learnt from past? • A drug addiction model. • A growth of the economy achieved by credit expansion works like drug addiction, • as it provides a pleasant reinforcer of further growth, and • an unpleasant symptom of recession associated with withdrawal. • Unfortunately, with repeated drug use results in addiction, and • which would intensify the magnitude and the duration of the unpleasant symptom. • In other words, with more successful preventions of recession by credit expansion, more substantial credit supply is necessary to keep the bubble booming, and the more torturous the results of a bubble implosion would be.
