Demand, Supply and Market Equilibrium

Supply and demand is the very heart of economics. In business, there is a constant battle to keep supply and demand in balance. You likely know that if the balance is disrupted that it can cause major issues. Think about what would happen if the demand for bananas suddenly went up, but the supply of bananas didn't increase. It would mean a major setback for the banana companies because there would be no way they could provide enough bananas for all the people who wanted to buy them. Our lessons will cover the ideas of supply and demand, so you can better understand how businesses avoid disasters that can occur when the system is out of balance.

Market demand represents the need for a product. Learn how businesses project what the market demand will be so that they can keep their production on track and not produce too much or too little of their products. Study demand schedules and find out what purpose they serve in the process of meeting market demand.

Market supply is the amount of products a business has available. As you know, supply goes hand-in-hand with demand. Our lessons will show you how a supply schedule is created and how it is used to ensure a good supply and demand balance.

Charts, graphs and other measurement processes are used to help businesses stay on track with supply and demand. As you watch the lessons, you'll learn about the Law of the Downward Sloping Demand Curve. See what happens when demand curves are downward sloping. Along the same lines, you'll learn about upward sloping supply curves and find out what it means when this occurs. Let our lessons explain these concepts to you through easy-to-understand, everyday examples. Also find out what market equilibrium is and learn how to calculate it. Thanks for watching!
