What are the unstable systems?
In financial markets, economic bubbles occur when the prices of assets, such as stocks or real estate, become inflated beyond their intrinsic values due to speculative buying.
The bubble is structurally unstable because a small event, such as a change in investor sentiment or economic indicators, can trigger a rapid and substantial collapse in asset prices.
