Understanding how people shop is really important in microeconomics. It helps us look at two key ideas: utility and marginal utility. Utility is simply the satisfaction or happiness a person feels when they buy and use goods and services. Preferences are what guide people in deciding what to buy.
Preferences are the unique likes and dislikes of each person. They show us how people see different products and services. These preferences can come from a variety of things, like personal experiences, culture, and friends.
For instance, think about Alex and Jamie. Alex loves sweet foods, while Jamie is all about salty snacks. This difference influences what they buy at the grocery store. If they see chocolate bars and potato chips, Alex will be happier grabbing a chocolate bar. On the other hand, Jamie will enjoy getting a bag of chips more than chocolate.
Utility is usually talked about in two ways: total utility and marginal utility.
Let's say Alex feels a total utility of 10 from eating two slices of pizza. If he eats a third slice and his total utility jumps to 15, that means the marginal utility of the third slice is 5. This shows how our happiness can change based on how much we eat or use.
Diminishing Marginal Utility: As people eat or use more of something, their satisfaction tends to go down. For example, if Alex keeps eating pizza, he might enjoy each slice less than the one before. The first slice is super satisfying, but the second one is a bit less enjoyable, and the third one even less. This is why people often choose a variety of foods instead of just piling on one kind.
Personal Value of Products: Everyone has different preferences, which means they will see the value of different products in their own ways. For instance, a video game lover might feel really happy about buying a new console, while someone who isn’t into gaming might not think much of it.
Budget Limits: People have to think about their budgets when deciding what to buy. Preferences help shoppers figure out which goods will make them happiest while staying within their budget. For example, if Alex and Jamie each have $20, they will spend their money based on what they like. Alex might grab a chocolate bar and a small cake, while Jamie may choose a bag of chips and a soda.
Consumers always want to get the most satisfaction for their money based on their tastes and limits. This is where consumer choice theory comes in. It says that people will tend to choose products that give them the most happiness for every dollar they spend.
If Alex has a choice between two things—a chocolate bar for 4 that gives him a utility of 20—he will figure out which one gives him more value per dollar. Both choices give him $5 of utility per dollar spent. But in the end, what he picks will depend on what he feels like eating at that moment.
In short, preferences play a big role in deciding how satisfied consumers feel. They guide choices and influence how happy people are with different products. By understanding preferences, along with total and marginal utility, we get a better idea of how people shop and make decisions. Preferences not only show what products people are interested in but also affect how they use their money to get the most happiness possible.
