Introduction to Supply and Demand

• Supply and demand are fundamental concepts in economics that illustrate how markets function.

• The phrase "supply and demand" is often humorously noted as a simple way to describe economics (e.g., teaching a parrot to say it).

Overview of Supply and Demand

• Supply: Refers to the quantity of a good or service that producers are willing and able to sell at various prices.

• Demand: Represents the quantity of a good or service that consumers are willing and able to purchase at different prices.

Importance in Economics

• Supply and demand are essential for understanding market behavior and pricing mechanisms in various markets.

• They are integrated into broader economic theories, such as aggregate supply and aggregate demand, which look at the economy as a whole rather than individual goods.

Structure of the Class

• The class will begin with an overview of demand as a crucial component of supply and demand.

• Discussions will involve graphs related to trade, demonstrating how both supply and demand influence market interactions.

• A focus on macroeconomics will involve more complex concepts like aggregate supply and aggregate demand later in the semester.
