General Equilibrium Theory

Definition of General Equilibrium Theory

General Equilibrium Theory is a concept in economics that analyzes the behavior of supply and demand across multiple markets, establishing a state of balance or equilibrium. This theory was pioneered by the French economist Léon Walras in the late 19th century, emphasizing how various markets interact and lead to overall economic stability rather than exploring single markets in isolation, as seen in Partial Equilibrium Theory.

Key Concepts

• Supply and Demand Interaction: At the heart of general equilibrium is the assertion that supply and demand in different markets interact, creating a ripple effect throughout the economy.
• Price Equilibrium: Through the balance of competing demands and supplies, various goods will reach a price point where quantity supplied equals quantity demanded.
• Interconnectedness of Markets: Changes in one market can greatly affect others due to economic interconnectedness.

Related Terms

• Partial Equilibrium: Analysis focused only on a single market without considering broader economic impacts; akin to examining a single cell in a body without considering the entire organ.
• Market Equilibrium: The state where market supply and demand balance each other, resulting in stable prices.
• Walras’s Law: The principle that if all but one market are in equilibrium, the last market must also be in equilibrium, even if it’s due to an unbalanced flow of resources.

• “In economics, there’s no such thing as a free lunch… unless you’re in general equilibrium. Then you might just find some leftovers!” 🍽️
• Did you know? Léon Walras was so dedicated to demonstrating his theory that he once said he woke up every morning trying to find prices that balance like a see-saw! Now that’s commitment! ⚖️

Frequently Asked Questions

1. What is the main difference between General Equilibrium Theory and Partial Equilibrium Theory?

   • General equilibrium considers multiple markets’ interactions, whereas partial equilibrium focuses on individual markets in isolation.

2. Why is General Equilibrium Theory significant in economics?

   • It helps economists understand the systemic effects of market changes and devise policies that consider the whole economy.

3. Can General Equilibrium ever truly be achieved?

   • In reality, markets are often dynamic and external factors can disrupt equilibrium, but the theory provides a helpful framework for analysis.
