Page "Economic bubble" Paragraph 35

Some regard bubbles as related to inflation and thus believe that the causes of inflation are also the causes of bubbles.

Others take the view that there is a " fundamental value " to an asset, and that bubbles represent a rise over that fundamental value, which must eventually return to that fundamental value.

There are chaotic theories of bubbles which assert that bubbles come from particular " critical " states in the market based on the communication of economic factors.

Finally, others regard bubbles as necessary consequences of irrationally valuing assets solely based upon their returns in the recent past without resorting to a rigorous analysis based on their underlying " fundamentals ".
