An economic bubble or asset bubble sometimes also referred to as a speculative bubblea market bubblea price bubblea financial bubblea speculative maniaor a balloon is a situation in which asset prices appear to be based on implausible or inconsistent views about the future.

Many explanations have been suggested, and research has recently shown that bubbles may appear even without uncertainty[6] speculation[7] or bounded rationality[8] in which case they can be called non-speculative bubbles or sunspot equilibria.

In such cases, the bubbles may be argued to be rational, where investors at every point are fully compensated for the possibility that the bubble might collapse by higher returns. These approaches require that the timing Reflectionss the bubble collapse can only be forecast probabilistically and the bubble process is often modelled using a Markov switching model.

More recent theories of asset bubble formation suggest that these events are sociologically driven. For instance, explanations have focused on emerging social norms [8] and the role that culturally-situated stories or narratives play in these events.

Because it is often difficult to observe intrinsic values in real-life markets, bubbles are often conclusively identified only in retrospect, once a sudden drop in prices has occurred. Such a drop is known as a crash or a bubble burst. In an economic bubble, prices can fluctuate erratically and become impossible to predict from supply and demand alone.

This was one of the earliest modern financial crises; other episodes were referred to as "manias", as in the Dutch tulip mania. The metaphor indicated that the prices of the stock were inflated and fragile — expanded based on nothing but air, and vulnerable to a sudden burst, as in fact occurred.

There are different types of bubbles, with economists primarily interested in two major types of bubbles:. An equity bubble is characterised by tangible investments and the unsustainable desire to satisfy a legitimate market in high demand. These kind of bubbles are characterised by easy liquidity, tangible and real assets, and an actual innovation that boosts confidence. Two instances of an equity bubble are the Tulip Mania and the dot-com bubble. A debt bubble is characterised by intangible or credit based investments with little ability to satisfy growing demand in a non-existent market.]
