Disequilibrium refers to a condition in a market where there is a significant imbalance between demand and supply, causing market prices to not adjust sufficiently to clear the market. This often leads to excess demand (shortage) or excess supply (surplus).
Causes of Disequilibrium
Disequilibrium can be the result of numerous factors including but not limited to:
- Sudden Changes in Demand: An unexpected increase in consumer desire for a product or service.
- Sudden Changes in Supply: A disruption in production or an influx of goods surpassing expected levels.
- Price Stickiness: Prices do not adjust quickly due to factors such as menu costs, contracts, or regulations.
- External Shocks: Economic events such as natural disasters, geopolitical events, or financial crises.
Types of Disequilibrium
Excess Demand (Shortage)
Occurs when the quantity demanded exceeds the quantity supplied at the current price. This leads to an upward pressure on prices as consumers compete for the limited goods.
Excess Supply (Surplus)
Occurs when the quantity supplied exceeds the quantity demanded at the current price. This causes a downward pressure on prices as suppliers attempt to sell off excess goods.
Special Considerations
- Market Mechanisms: Over time, most markets self-correct through mechanisms like price adjustments and changes in production levels.
- Government Intervention: Policies such as price floors and ceilings can perpetuate disequilibrium if they prevent prices from reaching equilibrium levels.
- Persistent Disequilibrium: Some argue that markets are constantly in a state of disequilibrium due to ever-changing factors affecting demand and supply.
Examples
- Oil Market: Sudden geopolitical events causing an unexpected drop in oil supply, creating a shortage, leading to higher oil prices.
- Housing Market: An increase in demand due to urbanization can lead to shortage and skyrocketing housing prices.
- Agriculture: Good weather leading to a bumper harvest can cause excess supply and falling prices for crops.
Historical Context
Historically, significant economic events such as the Great Depression and the 2008 Financial Crisis have been studied extensively for their periods of observable disequilibrium. During these times, markets experienced substantial imbalances that required extensive interventions for stabilization.
Applicability
Disequilibrium concepts are applicable in various sectors such as:
- Retail and Wholesale
- Financial Markets
- Real Estate
- Labor Markets
Comparisons to Related Terms
- Equilibrium: A market condition where the quantity supplied equals the quantity demanded, and there is no pressure for price change.
- Market Dynamics: The forces of demand and supply interacting in varying degrees of equilibrium and disequilibrium.

Summary
Disequilibrium highlights the dynamic nature of markets where shifts in demand and supply can lead to temporary imbalances. Understanding these imbalances is crucial for policymakers, businesses, and consumers as they navigate the complexities of market interactions. While markets usually adjust to restore equilibrium, the study of disequilibrium provides essential insights into the transient states that can significantly impact economic stability.
