Definition of Equilibrium
Equilibrium in economics refers to the state in which market supply and demand balance each other, resulting in stable prices for goods and services. When supply meets demand, there’s no inherent pressure for the market to change, leading to a calm sea of market activity—and hopefully, fewer gray hairs for investors!
Key Characteristics of Equilibrium:
- Consistent Behavior: Market participants have no incentive to alter their behaviors when prices and supply align perfectly.
- No Incentive to Change: With a balanced market, consumers and producers enjoy a tranquility akin to finding the perfect couch at a yard sale.
- Dynamic Process: Although it may seem static, the equilibrium process is always adjusting in response to shifts in supply and demand.
Equilibrium vs Disequilibrium
| Feature | Equilibrium | Disequilibrium |
|---|---|---|
| Supply and Demand | Balanced | Imbalanced: excess supply or demand |
| Price Stability | Prices are stable | Prices are volatile |
| Market Conditions | No incentive for change | External factors cause shifts |
| Examples | Real estate market during normal | Oil prices after a sudden geopolitical event |

- Market Clearing Price: The price at which the quantity of goods supplied equals the quantity demanded. It’s our ideal “meet-cute” in the economy!
- Elasticity: The degree to which the quantity supplied or demanded changes in response to price changes. Think of it as the yoga instructor of economic measures—stretchy and flexible!
- Shortage/Supply Shock: A sudden decrease in the supply of goods, often leading to rising prices—much like running out of toilet paper during a hurricane.
