Price in Economics: Meaning, Determination and Role

Introduction

In this section, you will learn about price and the factors which affect it. Price is the cost that the buyer pays to own an item. Prices play an important part in an economy. By the end of this lesson, you should be able to:

• Describe price in the economy.
• Discuss the factors that affect pricing in the economy.

Key Ideas

• Price is the amount of money that a buyer pays to a seller in exchange for goods and servicesfile-4nhc52ik5fw4vanxitwoua. In other words, price in economics refers to the monetary value required to purchase a product or servicebritannica.com.

• The interaction between buyers (demand) and sellers (supply) in the market determines the market price for a commodityfile-4nhc52ik5fw4vanxitwoua. In a free market (with no government price controls), the forces of supply and demand will settle at an equilibrium price where quantity supplied equals quantity demandedimf.org.

• Factors that affect pricing in the economy include scarcity, durability, and usefulnessfile-4nhc52ik5fw4vanxitwoua, among others. These factors influence how high or low a price can go for a given good or service.

Meaning of Price

Price is essentially the value of a good or service expressed in money terms – it is what buyers pay and sellers receive in a transactionbritannica.com. Price can also be seen as a measure of a product’s value, since it reflects how much people are willing to give up (in terms of money) to obtain it. Price plays an essential role in the economy: when prices are allowed to change naturally, they help distribute goods and services to those who want them and signal how much of certain products people needbritannica.com. This system of relying on prices to allocate resources is known as the price mechanism, and it assumes that prices will adjust until supply matches demand in the marketbritannica.com.

To understand how important an influence price has on buyers and sellers, consider the following scenario:

A local baker made a biscuit that was very popular in the community. The baker sold each biscuit for Gh¢2. The baker sold every biscuit made each day and still people wanted more – he was making a good profit from selling the biscuits.

Activity a: Refer to the scenario above and answer the following questions:

1. Describe two ways the baker could make more profit each day.
2. What might happen to the baker’s sales if another shop started selling a similar biscuit for Gh¢1? Explain your answer.
3. What could the baker do to keep sales at the same level?

Discuss your responses with a friend.

From the activity above, you can see how price can change the behavior of both producers and consumers. If the baker raises the price too high, consumers will buy fewer biscuits or seek a cheaper alternative. At lower prices, consumers would buy more – but perhaps from the competitor offering Gh¢1 biscuits. In other words, a less expensive price elsewhere is more attractive, and if the producer’s price is too high, many consumers will not buy or will look for a cheaper option. Price therefore plays a key role in every economy as it determines how buyers and sellers make their decisions on how much of a commodity to buy and sellfile-4nhc52ik5fw4vanxitwouafile-4nhc52ik5fw4vanxitwoua.

Role and Functions of Price in the Economy

As demonstrated in the baker example, price serves as a powerful signal and incentive for market participants. High prices encourage producers to supply more (to maximize profit) and discourage consumers from buying as much, whereas low prices encourage consumers to purchase more and may dissuade producers from supplying as much. In this way, prices help balance what producers are willing to sell with what consumers are willing to buy, guiding the economy toward an equilibriumbritannica.com. If there is too much of a product on the market, the price tends to fall and producers cut back production; if a product is scarce and in high demand, the price rises and producers are motivated to produce morebritannica.com. Through this mechanism, price plays a critical role in allocating resources and coordinating economic activity.

In fact, prices in a market economy perform three primary functions. They signal to producers what to produce (and how much) by indicating what consumers want; they provide incentives (and disincentives) to producers and consumers – for instance, higher prices incentivize producers to increase supply, while lower prices encourage consumers to buy more; and they help ration goods and services, determining who gets what in conditions of limited supplybritannica.com. In summary, prices help producers decide which goods to produce and in what quantities, influence the methods of production (since producers will seek cost-effective ways when prices or competition pressure them), and determine who will get the goods based on who is willing and able to pay the market pricebritannica.com. These are often referred to as the signaling, incentive, and rationing functions of price in an economy.

It’s important to note that in a competitive market with many buyers and sellers, no single participant sets the price. Rather, the market-clearing price (equilibrium price) emerges where the quantity supplied equals the quantity demandedimf.org. If a price is above this equilibrium, an excess supply (surplus) will force sellers to lower prices; if it’s below equilibrium, excess demand (shortage) will drive the price up. In this way, price determination is largely governed by supply and demand forces in a free marketbritannica.com. (However, in some cases governments may intervene with price controls like minimum or maximum prices, but in a free market the price is set by market forces.) For a deeper explanation of how equilibrium price is reached, you can refer to Investopedia’s definition of equilibrium which describes how markets tend to move toward a balance where supply meets demandinvestopedia.com.

Factors That Affect Pricing in the Economy

The price of a commodity can change due to various factors. Three important factors are scarcity, durability, and usefulness of the good. Understanding these factors helps consumers and businesses make decisions about pricing, purchasing, and resource allocation in an economyfile-4nhc52ik5fw4vanxitwouafile-4nhc52ik5fw4vanxitwoua. Below, we discuss each factor and how it influences price:

• Scarcity: Scarcity refers to the limited availability of a good or service relative to the demand for it. When something is scarce, it tends to be more valuable because people are willing to pay more to obtain itfile-4nhc52ik5fw4vanxitwoua. In other words, if supply is low and demand is high, the price will rise – this is a basic application of the law of supply and demand. Conversely, when supply exceeds demand for a product, prices typically fallfile-4nhc52ik5fw4vanxitwoua. For example, rare gemstones like diamonds are priced much higher than ordinary commodities like water because diamonds are relatively scarce while water is generally abundant. Scarcity forces buyers to compete for the limited goods, driving up the price. This concept of scarcity is fundamental in economics: it highlights that resources are limited, so goods that are scarce command higher prices as people prioritize obtaining theminvestopedia.com.

• Durability: Durability refers to how long a good can last and continue performing its intended function. More durable goods often have higher prices because they provide value over a longer period. Consumers are usually willing to pay a premium for items that will last longer, since a durable good’s cost can be spread over many years of usefile-4nhc52ik5fw4vanxitwoua. Additionally, producing highly durable goods may require higher-quality materials or advanced engineering, which increases production costs and, in turn, the selling pricefile-4nhc52ik5fw4vanxitwoua. Durable goods also tend to retain their value better in the resale or second-hand market, further contributing to their higher pricefile-4nhc52ik5fw4vanxitwoua. For example, a piece of furniture made from solid hardwood will typically cost more than one made from cheap particle board, because the hardwood piece is expected to last much longer while maintaining its look and functionality. All else being equal, a more durable good is more valuable (and thus pricier) than a less durable good, since it provides more “service” over timemises.org.

• Usefulness: Usefulness (or utility) is the degree to which a good or service satisfies consumer needs and wants. The more useful or necessary a product is perceived to be, the higher its demand tends to be – and higher demand can drive prices up, especially if supply is limitedfile-4nhc52ik5fw4vanxitwoua. Products that offer unique features, solve specific problems, or provide significant benefits are often priced higher because consumers value their usefulness. Conversely, goods with limited usefulness or plenty of substitutes may have lower prices, since consumers won’t be willing to pay much for them. For example, a smartphone with advanced features and capabilities (high usefulness) usually commands a high price, whereas a basic mobile phone that only calls and texts (limited features) will be much cheaperfile-4nhc52ik5fw4vanxitwoua. In summary, when a product is very useful or even essential, people are generally prepared to pay a premium for it, reflecting its higher utility value in the price.

Now, let’s apply these concepts with some activities that illustrate how scarcity, durability, and usefulness affect price-related decision making:

Activity b: Understanding Scarcity and Price
This activity will help you understand the concept of scarcity and how it affects price-related decision-making. Work in a group of 8–10 students (your teacher may organize the groups). One person in the group will act as the seller, while all the others are buyers.

1. Set Up:

• Give each buyer a fixed amount of play money (e.g., Gh¢30 per buyer).
• The seller should display a few items (or pictures of items) available for purchase – make sure there are fewer items than buyers (for example, 10 students but only 7 items available). Do not put price tags on the items.

2. Shopping:

• Buyers can walk around and “shop” for the items using their play money.
• Each buyer must decide which items to buy and how much they are willing to pay for each.
• The seller listens to offers and decides which buyer gets to purchase each item based on the offers made (who is willing to pay the most).

3. Discussion: (after the shopping phase) Discuss these questions within your group:

• Which items were most popular, and why?
• How did scarcity affect the prices of the items (what happened when many people wanted the same item but there were not enough for everyone)?
• Did anyone run out of money before getting what they wanted? What does this tell you?
• How did buyers decide what to buy (what factors did they consider most important)?

4. Reflection:

• Individually, write a short paragraph on what you learned about scarcity from this activity and how the scarcity of items influenced your decisions as a buyer.

(After completing your reflection, discuss your thoughts with a friend or classmate to compare insights.)

Activity c: Understanding Durability and Price
This activity will help you understand the concept of durability and how it affects price-related decision-making. Durability relates to how long a good will last (and remain useful).

Choose one category of product from the following list for this activity: writing pens, smartphones, footwear, or backpacks. Once you have chosen a category, do the following:

1. Obtain or research two different specific items in your chosen category that have different levels of durability. For example, if you chose pens, you might compare a cheap plastic pen with a high-quality metal pen. (If you cannot physically examine the items, use the internet to research their features and build quality. For branded items, you can look up well-known durable brands like Apple iPhones, Nike trainers, or Patagonia backpacks, and compare them with a less expensive or store-brand alternative in the same category.)
2. Examine or note details about both items, focusing on aspects related to durability: the build quality, materials used, expected lifespan, warranty (if any), etc. Write down facts such as the materials (plastic vs metal, etc.), and any information on how long the item is expected to last or remain in good condition.
3. Considering the price of each item and the durability information you gathered in step 2, decide which item you would choose to buy and why. (In other words, does the more durable item justify its higher price, or would you prefer the cheaper, less durable one? How do you balance cost vs. longevity?)
4. Explain your choice in a short paragraph. Discuss how durability influenced your decision and mention if any other factors (for example, brand reputation, design, or immediate cost savings) were important in your choice.

Activity d: Understanding Usefulness and Price
This activity will help you understand the concept of usefulness and how it affects price-related decision-making. Consider the following five products, all of which are very useful for a Senior High School student:

1. Smartphone:

• Essential for communication, accessing social media, and even doing schoolwork (research, educational apps, etc.).
• Popular brands include Apple, Samsung, and Google (which tend to be pricier due to advanced features).

2. Laptop:

• Very useful for completing school assignments, online research, and entertainment.
• Highly recommended brands for durability and performance include Dell, HP, and Apple (MacBook).

3. Backpack:

• Ideal for carrying textbooks, notebooks, a laptop, and other daily school essentials.
• Durable options (which might cost more) include brands like Patagonia, North Face, and Herschel that are known for high quality.

4. Wireless Earbuds:

• Great for listening to music, educational podcasts, or taking calls on the go.
• Examples are Apple AirPods, Samsung Galaxy Buds, and Jabra Elite – these are popular models with various price points.

5. Reusable Water Bottle:

• Encourages you to drink water regularly (staying hydrated) and is environmentally friendly.
• Brands like Hydro Flask, Nalgene, and S’well offer durable, high-quality bottles in this category.

After reviewing the list of products above, carefully consider their usefulness and prices, then answer the following:

1. Rank these five products in order of usefulness to you personally. Give the most useful product a rank of 5 and the least useful a rank of 1. (This is a decision-making exercise – think about which item you cannot do without versus which is nice-to-have but not essential.)
2. For each product, write down the reasons for the ranking you gave. Explain why you find one product more useful than another. (Your reasons should reflect the usefulness or importance to you – for example, you might rank the laptop highest because you can use it for school projects, whereas earbuds might be lower if you consider them more of a luxury than a necessity.)
3. Now, research or recall the approximate price of each of these products (you can use actual prices in stores or estimates). Then rank the products in order of their price — the most expensive product gets rank 5 and the least expensive gets rank 1. Once you have both sets of rankings (usefulness and price), compare them. Analyze your findings: are the most useful items also the most expensive? Or are some less-useful items expensive and vice versa? Think about reasons for any differences or similarities you observe. Would you change any of your usefulness rankings after considering the prices? Why or why not?
4. Compare your usefulness and price rankings with those of your friends or classmates. Are their rankings the same as yours? Discuss why different individuals might have different opinions on which products are most useful. (People have different needs and preferences, which can influence how useful they find an item – and thus how much they might be willing to pay for it.)

(Through this activity, you will see that an item’s usefulness does not always directly correspond to its price. Some very useful items might be relatively cheap, and some expensive items might not be very useful to you personally. It leads to an interesting discussion on value: a product’s price is influenced not just by its inherent usefulness, but also by factors like production cost, branding, and market demand.)

Review Questions

Test your understanding of price in economics with these questions:

1. Define the concept of price.
2. Explain the effect on an economy of high demand, limited supply, and rising prices. (Hint: Think about scarcity and how producers and consumers react to high demand when goods are limited.)
3. Explain the effect on an economy of low demand, high supply, and falling prices. (Hint: Consider what happens when there is an excess supply of goods but not enough buyers – how do prices adjust, and what might producers do?)
4. Describe how scarcity, durability, and usefulness affect the price of goods. (Provide a brief explanation for each factor.)

This article by the International Monetary Fund provides a deeper look at the concept of price, different types of prices (such as spot price, forward price, bid/ask price, etc.), and how prices clear marketsimf.orgimf.org. It’s a great read to broaden your understanding of how economists view prices. Read it here.
2. Video – Supply and Demand: Introduction to Supply and Demand. Watch this short YouTube video that explains how the forces of supply and demand interact to determine market prices, with examples. It reinforces the concept of market equilibrium (where supply equals demand) and why prices rise or fall in response to shortages or surpluses. Watch the video here.

By understanding price determination and the functions of price in the economy, you’ll have a clearer picture of how markets allocate resources and how various factors influence the prices you see every day – from the cost of your lunch to the latest smartphone. Pricing is a central concept in economics because it connects to almost everything: consumer behavior, producer decisions, and the overall allocation of scarce resources in society.
