Background
Self-fulfilling expectations refer to situations in which individuals’ expectations concerning the future lead them to take actions that ultimately cause the anticipated outcome to occur. This concept plays a pivotal role in various economic scenarios, particularly in markets where speculations about future prices influence present behavior.
Historical Context
The idea of self-fulfilling expectations has historical roots in prophetic concepts, which were adopted and formalized by economists to explain market dynamics. Influential works by economists such as John Maynard Keynes have highlighted the significance of expectations in shaping economic activities.
Definitions and Concepts
Self-fulfilling expectations are expectations that induce individuals to take actions which, in turn, bring about the anticipated situation. This phenomenon can be widely observed in financial markets where expectations of price movements prompt investors to buy or sell assets, thereby causing the expected price changes.
Major Analytical Frameworks
Classical Economics
In classical economics, self-fulfilling expectations do not play a significant role since classical theory assumes markets always clear and that prices are determined by fundamental supply and demand factors.
Neoclassical Economics
Neoclassical economics acknowledges the role of expectations in influencing economic outcomes, particularly through the lens of rational expectations theory. Here, individuals form forecasts about the future that, on average, end up being correct.
Keynesian Economics
John Maynard Keynes emphasized the importance of expectations in economic behavior. He suggested that investor expectations could lead to fluctuations in economic activities, such as investment and consumption, thus impacting the overall economy.
Marxian Economics
While Marxian economics does not specifically address self-fulfilling expectations, it acknowledges the broader role of perceptions and beliefs in shaping social and economic structures.
Institutional Economics
Institutional economics emphasizes the role of institutions and norms in shaping economic behavior, including how self-fulfilling expectations can be guided by institutional frameworks.
Behavioral Economics
Behavioral economics deeply investigates self-fulfilling expectations, showing how cognitive biases and herd behavior can lead to market inefficiencies and bubbles.
Post-Keynesian Economics
Post-Keynesian economists further explore the significance of expectations, noting that anticipations of future economic conditions significantly shape current economic decisions and outcomes.
Austrian Economics
Austrian economics considers the subjective nature of expectations and acknowledges how individual decision-making processes influence market dynamics, often highlighting the unintended consequences of these expectations.
Development Economics
In development economics, self-fulfilling expectations can explain how investor confidence affects economic growth, investment flows, and the development outcomes of emerging economies.
Monetarism
Monetarists recognize the influence of expectations on inflation and how anticipated monetary policies can impact economic behavior, often aligning with the rational expectations hypothesis.
Comparative Analysis
Different economic schools offer varied perspectives on the significance and mechanisms of self-fulfilling expectations. While classic views may undervalue their role, more modern frameworks like Keynesian and behavioral economics provide substantial evidence and mechanisms by which expectations shape economic outcomes.
Case Studies
Case studies include asset price bubbles, where anticipations of rising asset values lead more participants to invest, thereby increasing demand and inflating prices.

Related Terms with Definitions
- Asset Bubble: A market condition where the prices of assets are much higher than their fundamental values due to speculative buying.
- Rational Expectations: The hypothesis that individuals form forecasts about the future based on all available information, and on average, these forecasts are correct.
- Speculative Markets: Markets in which the trading prices of goods are determined primarily by traders’ beliefs about future price changes rather than intrinsic value.
- Self-Frustrating Expectations: Opposite of self-fulfilling expectations, where actions based on anticipations lead to outcomes that contradict the original forecasts. For example, increased production due to high price expectations leading to price drops due to excess supply.
