Financial bubbles refer to periods during which the prices of assets, such as real estate, stocks, or commodities, inflate rapidly due to speculative trading. These bubbles often culminate in abrupt market crashes, leading to significant economic consequences. This comprehensive entry delves into the historical context, types, key events, and economic theories surrounding financial bubbles, offering a holistic understanding of their dynamics.
Historical Context
Early Financial Bubbles
- Tulip Mania (1636-1637): Often cited as the first recorded financial bubble, the prices of tulip bulbs in the Netherlands soared to unprecedented heights before collapsing.
- South Sea Bubble (1711-1720): The South Sea Company in Britain promised immense returns on investments, driving stock prices up before the inevitable crash.
20th and 21st Centuries
- Dot-com Bubble (1995-2000): The rapid growth in internet-based companies led to inflated stock prices, which crashed dramatically by 2000.
- Housing Bubble (2003-2008): Fueled by easy credit and speculative investments in real estate, housing prices peaked before plunging, precipitating the Global Financial Crisis.
Types and Categories
- Asset Bubble: Characterized by rapid increases in asset prices, like stocks, real estate, or commodities.

Detailed Explanations
Causes of Financial Bubbles

- Credit Expansion: Easy availability of loans can inflate asset prices.
- Behavioral Economics: Herd behavior and overconfidence among investors.
- Market Inefficiencies: Asymmetry of information and irrational exuberance.
Economic Theories and Models
The Greater Fool Theory
Suggests that investors can profit from buying overvalued assets, as long as there is a “greater fool” willing to purchase it at a higher price.
Hyman Minsky’s Theory
Outlined the stages of a financial bubble: displacement, boom, euphoria, profit-taking, and panic.
Mathematical Models
Gordon Growth Model
Used to value a stock by assuming constant growth in dividends:
where:
- \( P \) is the price of the stock,
- \( D_1 \) is the expected dividend next period,
- \( r \) is the required rate of return,
- \( g \) is the growth rate in dividends.
