What drives supply for goods and services? What about demand? How do prices help coordinate market activity? These are the sorts of questions that we’ll explore in this Alison course on microeconomics.

In this introductory course, you’ll learn some of the fundamental concepts in economics. You’ll discover the relationship between prices, demand, and supply – and how both consumers and suppliers respond to price changes. You’ll get to try your hand at reading demand and supply graphs and learn the factors that cause their curves to shift. You’ll also explore the concept of market equilibrium: where supply and demand intersect.

By the end, you’ll walk away grasping the building blocks of how the economy functions. And you’ll be ready to take on more challenging economic material!

This course will be ideal for students studying economics, as a resource for teachers, or for anyone who wants to gain a better understanding of the basics of how the economy works.
