Understanding Microeconomics
Microeconomics is the branch of economics that focuses on the actions of individuals and industries, including the dynamics of supply and demand, market structures, and consumer behavior. It contrasts with macroeconomics, which examines the economy as a whole, including national productivity and overall economic health.
Fundamental Concepts
The core principles of microeconomics revolve around several key concepts:
1. Scarcity: Resources are limited, which necessitates the need for choices and trade-offs.
2. Supply and Demand: These are the fundamental forces that determine prices and the allocation of resources in a market.
3. Opportunity Cost: The cost of foregone alternatives when a choice is made.
4. Market Efficiency: The concept that markets can allocate resources efficiently under certain conditions.
5. Elasticity: The responsiveness of quantity demanded or supplied to changes in price.
