Bubble

Background

Economic bubbles are phenomena where the price of an asset inflates rapidly to levels that are unsustainable in the long term, driven mainly by speculative activities. This process leads to an overall heightened asset market value that, at some point, inevitably collapses, often damaging economies.

Historical Context

Economic bubbles are not a recent phenomenon and have been recorded throughout history. Among the early examples are the Dutch tulip mania of 1636-37 and the South Sea Bubble of 1720. Each instance provides a compelling study of market behavior, investor psychology, and economic impact when speculation goes unchecked.

Definitions and Concepts

An economic bubble refers to a cumulative upward trend in the price of an asset largely sustained by speculative buying, thereby deviating significantly from the asset’s intrinsic value. When investors’ speculative behavior fuels price increases, the inflated market eventually becomes unsustainable and is susceptible to a sudden drop, or burst.

Major Analytical Frameworks

Classical Economics

In classical economics, an asset’s value is primarily derived from its inherent utility and production costs. Bubbles thus represent deviations from intrinsic value assumptions, largely dismissed as anomalies.

Neoclassical Economics

Neoclassical economics emphasizes market equilibrium and rational behavior. Bubbles are viewed as market inefficiencies arising due to information asymmetries, irrational exuberance, and herd behavior.

Keynesian Economics

Keynesian economics accounts for investor sentiment and animal spirits in driving bubbles. Market participants’ expectations of continued growth in asset prices lead to speculative investments, exacerbating bubbles.

Marxian Economics

Marxian economists might explain bubbles as the manifestation of capitalist overproduction and the search for surplus value, causing periodic crises within the capitalist system.

Institutional Economics

Institutional economics investigates the role of financial institutions, regulatory frameworks, and socio-economic structures in the formation and bursting of bubbles.

Behavioral Economics

Behavioral economics explores how cognitive biases, herd behavior, and irrational decision-making among investors contribute to the creation and bursting of economic bubbles.

Post-Keynesian Economics

Post-Keynesians may stress the role of financialization, leverage, and speculative finance in increasing economic instability about bubble formations.

Austrian Economics

Austrian economics emphasizes the malinvestments that occur due to artificial low-interest rates and credit expansions, seeing bubbles as consequences of loose monetary policies.

Development Economics

In developing economies, bubbles can occur in asset and real estate markets, similar to advanced economies. However, specific structural and institutional factors unique to these economies are also examined.

Monetarism

For monetarist economists, bubbles arise in part due to excessive monetary expansion. Control over money supply is viewed as a mechanism for preventing the formation of bubbles.

Comparative Analysis

Different economic schools of thought provide various analytical lenses to examine economic bubbles. While some prioritize market efficiency and equilibrium, others examine psychological, structural, and policy-centric explanations. Understanding these perspectives can enrich the analysis of financial crises and help develop preventive measures.
