The capacity of a commodity to satisfy human want is known as the utility of the given commodity. Utility plays important role in understanding the behaviour of consumers and enable producers to allocate resources accordingly. Consumers always choose the product that offer more utility values comparatively. By evaluating utility, economists can assess consumer preferences, which serve as a cornerstone for theories related to demand and market dynamics. So, let’s decode marginal utility and total utility in detail.
Utility is a fundamental concept in economics that refers to the satisfaction or value that individuals derive from consuming goods and services. It plays a crucial role in understanding consumer behavior and decision-making.
Types of utilities in economics
There are several types of utilities in economics as like:
1. Form utility
This type of utility refers to the value that is added to a product or service through its physical transformation or alteration. For example, a raw material like cotton is transformed into a finished product like a t-shirt, creating form utility.
2. Place utility
Place utility is the value that is created by making a product or service available at a convenient location for consumers. For instance, a grocery store located near residential areas provides place utility by offering easy access to essential goods.
3. Time utility
Time utility is created by making a product or service available at the right time when consumers need it. For example, an online streaming platform that releases new episodes of a popular TV series at a specific time creates time utility.
4. Possession utility
Possession utility refers to the value that is created by transferring ownership or possession of a product or service to consumers. For instance, a car dealership provides possession utility by enabling customers to own a vehicle.
5. Information utility
Information utility is the value that is created by providing relevant and useful information to consumers about a product or service. For example, product reviews and specifications help consumers make informed decisions, creating information utility.
Useful examples of utilities
Examples of utilities can be found in various aspects of our daily lives. When you buy a new smartphone, you derive form utility from its sleek design and advanced features.
The convenience store near your workplace provides place utility by offering quick access to snacks and beverages.
Online shopping platforms create time utility by delivering products to your doorstep within a specified time frame.
Possession utility can be experienced when you purchase a new home or a piece of jewelry.
Information utility is evident when you read product reviews before buying a book or when you compare prices of different laptops before making a purchase.
Cardinal utility and ordinal utility
Understanding cardinal or ordinal, aids in analyzing how consumers make choices in the marketplace. This analysis is crucial for economists and policymakers to predict demand patterns, understand consumer behavior, and develop effective policies for economic growth and consumer welfare.
Cardinal utility
Cardinal utility assigns a numerical value to the level of satisfaction derived from a good or service. This allows economists to quantify utility, suggesting that one can measure how much more satisfaction a consumer derives from one good compared to another.
Consider, if a consumer derives ten units of utility from product A and six units from product B, the cardinal approach implies that product A delivers a higher level of satisfaction.
Ordinal utility
Ordinal utility emphasizes the ranking of preferences without attempting to quantify them. It posits that consumers can rank their preferences among different goods or services (first, second, third, etc.), reflecting their tastes and choices without assigning specific numerical values.
This approach is prevalent in modern economic analysis, particularly when exploring indifference curves and consumer equilibrium, which show how consumers achieve maximum satisfaction given their budget constraints.
Difference between Marginal utility and total utility
Marginal Utility
Marginal utility refers to the additional satisfaction or benefit that a consumer derives from consuming one additional unit of a good or service. It is important to note that marginal utility diminishes as consumption increases.
For example, let’s say you are eating a slice of pizza. The first bite of the pizza will provide you with a high level of satisfaction, or utility. However, as you continue to eat more slices, the satisfaction you derive from each additional slice will decrease. This is because the marginal utility of each additional slice diminishes.
Total Utility
Total utility, on the other hand, refers to the overall satisfaction or benefit that a consumer receives from consuming a certain quantity of a good or service. It is the sum of the marginal utilities of each unit consumed.
Using the same example of eating pizza, the total utility would be the combined satisfaction you derive from eating all the slices of pizza. As you eat more slices, the total utility will continue to increase, but at a decreasing rate.
Graphical Representation of Marginal Utility
Graphically, marginal utility is represented by a downward-sloping curve. The x-axis represents the quantity consumed, while the y-axis represents the marginal utility.
Initially, the curve is steep, indicating high marginal utility. As the quantity consumed increases, the curve becomes flatter, indicating diminishing marginal utility.It is important to note that the marginal utility curve can differ for different individuals and goods.
For example, a person who loves chocolate might experience a slower decline in marginal utility as they consume more chocolate compared to someone who is not a fan of chocolate.
Graphical representation of Total Utility?
Graphically, total utility is represented by an upward-sloping curve. Initially, as the quantity consumed increases, the total utility increases at an increasing rate. However, as the quantity consumed continues to increase, the total utility starts to increase at a decreasing rate. Eventually, it may even reach a point where the total utility starts to decline.
Relationship Between Marginal Utility and Total Utility
When marginal utility is positive and greater than zero, total utility increases. But, When marginal utility is zero, total utility is at its maximum. When marginal utility is negative, total utility decreases
Let’s go back to the pizza example. As long as each additional slice of pizza provides you with some level of satisfaction, the marginal utility is positive, and therefore, the total utility increases.
However, there will come a point where you start feeling full and the marginal utility of each additional slice becomes zero. At this point, the total utility is at its maximum. If you were to continue eating more slices, the marginal utility would become negative, and the total utility would start to decrease.
Role And importance of utilities
Utilities play a vital role in consumer behavior as they influence the choices individuals make when consuming goods and services. Understanding the role and importance of utilities can help businesses develop effective marketing strategies and meet the needs and preferences of their target customers.
Identifying consumer behaviour
One of the key roles of utilities in consumer behavior is that they affect the demand for goods and services. Consumers are more likely to purchase products that offer higher levels of utility and satisfaction. For example, a smartphone with advanced features and a user-friendly interface is likely to have higher demand compared to a basic model with limited functionality.
Decision making
Utilities also influence consumer preferences and decision-making. Consumers tend to choose products that provide the most value or utility for their money. They consider factors such as quality, price, convenience, and overall satisfaction. Businesses can leverage this understanding to differentiate their products and gain a competitive edge.
Forming consumer expectations
Furthermore, utilities play a role in shaping consumer expectations. When consumers experience high levels of utility from a particular product or service, they develop certain expectations regarding its performance and quality. Meeting or exceeding these expectations becomes crucial for businesses to maintain customer satisfaction and loyalty.Explaining the concept opportunity cost/ Importance of comparative advantage /The law of demand and supply
