What are microeconomic foundations?

Microeconomic foundations are like the building blocks that help explain how people and businesses make choices every day.

Imagine you have a lemonade stand. You decide how many cups of lemonade to make based on how much lemons, sugar, and water you have, and how much money you think you’ll get from selling them. That’s microeconomic foundations in action: they help explain why you choose to make 10 cups instead of 20 or why you raise the price when it's a hot day.

When people decide what to buy, how much to work, or whether to save their money, they’re using microeconomic foundations. It’s like choosing between your favorite toy and a new one, you think about how much you want it and how much money you have.

Businesses also use these building blocks. A bakery decides how many loaves of bread to make based on how many customers come in each day, just like how you decide how many lemonades to sell. They’re both using microeconomic foundations to help them make smart choices.
