An overview of how individuals and small businesses make decisions in the economy.
Have you ever wondered why a bag of chips costs 60.00? Every time you choose how to spend your allowance, you are acting as a scientist in the world of Microeconomics!
Economics is the study of how people use limited resources to satisfy unlimited wants. Microeconomics is a specific branch that looks at the economy through a microscope. Instead of looking at whole countries, it focuses on the 'small' parts: individuals, households, and firms (businesses). It explores how these players make decisions. For example, if the price of your favorite soda goes up by , microeconomics helps us predict if you will keep buying it or switch to water. It assumes that everyone tries to make the best choice possible with the money they have, a concept often represented by the budget constraint: , where is your total income.

If a scientist is studying how a single family decides to save money for a vacation, are they studying Microeconomics or Macroeconomics?
Answer
Microeconomics, because it focuses on an individual household's decision.
In microeconomics, we group everyone into two categories. First, we have Households. These are individuals or families who act as consumers. They buy goods (like clothes) and services (like tutoring). Second, we have Firms. These are businesses that act as producers. They use resources like labor and tools to create products. This creates a cycle: Households give their labor to Firms in exchange for wages, and then use those wages to buy the products Firms make. We can represent the total cost for a firm as , where is Total Cost, is Fixed Costs (like rent), and is Variable Costs (like ingredients).
Let's look at a simple microeconomic setup: 1. The Household: You want a cold drink on a hot day. You are the consumer. 2. The Firm: Your neighbor, Maya, sets up a stand. She is the producer. 3. The Decision: Maya spends on lemons and sugar. She decides to sell each cup for . You decide if the 'utility' (happiness) of the drink is worth your .
Because resources like time, money, and materials are scarce (limited), every society and business must answer three basic economic questions: 1. What to produce? (Should we make fidget spinners or board games?) 2. How to produce? (Should we use expensive robots or hire twenty people to build it by hand?) 3. For whom to produce? (Is this product for wealthy collectors or for everyday students?)
How a firm answers these questions determines their success and who gets to enjoy the goods in a market.
A bakery is deciding how to run their business: 1. What: They choose to make organic cupcakes. 2. How: They decide to use solar-powered ovens instead of gas ovens to save the environment. 3. For whom: They price cupcakes at each, targeting customers who care about organic food and have extra spending money.
