Welcome to the World of Markets!

Hello there! Welcome to your study notes for the "Markets" chapter of the Pearson Edexcel AS Business (8BS0) course. Whether you're a budding entrepreneur or just trying to figure out why the price of your favorite chocolate bar keeps going up, this chapter is for you. We’re going to explore how businesses find their place in the world, how prices are set, and why some markets change faster than a TikTok trend!

Don’t worry if some of this feels a bit "maths-heavy" or technical at first. We’ll break it down step-by-step with plenty of real-world examples.


1. Mass Markets vs. Niche Markets

In business, a market is simply any place where buyers and sellers meet to trade goods or services. However, not all markets are the same size!

Mass Markets

A mass market is a very large market where businesses sell products that appeal to almost everyone. Think of things like bottled water, toothpaste, or sliced bread.

  • Characteristics: Huge volume of sales, high competition, and usually lower prices.
  • Branding: Brands are vital here to help a product stand out (like Coca-Cola vs. Pepsi).

Niche Markets

A niche market is a small, specialized gap in a larger market. Businesses here sell products to a specific group of people with clear needs.

  • Characteristics: Lower volume of sales but often higher prices (premium prices). There is usually less competition.
  • Example: Instead of just "cars" (mass market), think "luxury electric supercars" (niche market).

Market Size and Market Share

To understand how well a business is doing, we look at two key numbers:

  1. Market Size: The total value or volume of sales in the whole market (e.g., "The UK coffee market is worth \$15 billion").
  2. Market Share: The percentage of that total size that one specific business owns.

The Formula:
\(\text{Market Share \%} = \frac{\text{Sales of a business}}{\text{Total Sales in the market}} \times 100\)

Quick Review: Mass markets = Everyone. Niche markets = Specialists. Market share = Your piece of the pie!


2. Dynamic Markets and Change

The word dynamic just means "constantly changing." Most markets today don’t stay still for long!

Why do markets change?

  • Online Retailing: The growth of the internet has changed how we shop. Businesses can now sell 24/7 to anyone in the world.
  • Innovation: New ideas and products (like smartphones replacing old Nokia bricks) create new markets and destroy old ones.
  • Adapting to Change: If a business doesn't change, it fails. Remember Blockbuster? They didn't adapt to online streaming, and now they are gone!

Risk vs. Uncertainty

These two sound similar, but in Business, they are different:

  • Risk: This is when a business takes a gamble where the outcomes are known. For example, a business knows that 1 in 10 new products usually fails. They can plan for this.
  • Uncertainty: This is when events happen that no one could predict (like a global pandemic or a sudden natural disaster). You can’t easily "calculate" uncertainty.

Key Takeaway: Markets are dynamic. To survive, businesses must innovate and manage risks constantly.


3. Demand: Why do we buy?

Demand is the amount of a product that consumers are willing and able to buy at a certain price.

Factors that shift Demand

If something other than price changes, the whole demand for a product might go up or down. Think of these factors:

  • Prices of Substitutes: If the price of iPhone goes up, demand for Samsung (the substitute) might go up.
  • Complementary Goods: These are items bought together (like Fish and Chips). If the price of fish goes up, people might buy fewer chips too!
  • Income: When people earn more, they buy more "luxury" items.
  • Fashions and Tastes: If a celebrity wears a certain brand, demand skyrockets!
  • External Shocks: Sudden events like bad weather or changes in the law.

Memory Aid: Think of demand as a "want." If people want it more (because they are richer or it's trendy), the demand curve shifts to the right.


4. Supply: Why do businesses sell?

Supply is the amount of a product that businesses are willing and able to provide to the market at a certain price.

Factors that shift Supply

  • Costs of Production: If the price of raw materials or wages goes up, it’s more expensive to make the product, so supply falls.
  • New Technology: Better machines make production faster and cheaper, so supply increases.
  • Indirect Taxes: If the government puts a tax on a product (like cigarettes), supply usually falls because it's more expensive for the business.
  • Subsidies: This is money the government gives to a business to help them produce more. This increases supply.

Key Takeaway: Supply is all about the "cost of doing business." If it's cheaper/easier to make, supply goes up!


5. Putting it Together: Supply and Demand Diagrams

Don't be scared of the graphs! Just remember two simple rules:

  1. Demand goes Down (from left to right).
  2. Supply goes to the Sky (upward from left to right).

Where the two lines cross is called the Equilibrium Price. This is the "perfect" price where everything produced is bought!

Example: If there is a "fashion trend" for reusable water bottles, the Demand curve shifts right. This causes the Equilibrium Price to rise.


6. Price Elasticity of Demand (PED)

This sounds complicated, but it just asks: "How much do customers care about a price change?"

The Formula

\(\text{PED} = \frac{\text{\% change in quantity demanded}}{\text{\% change in price}}\)

Understanding the Result

  • Price Elastic (> 1): Consumers are sensitive to price. If you raise the price a little, they stop buying it (e.g., a specific brand of chocolate). Think of a stretchy rubber band.
  • Price Inelastic (< 1): Consumers are not sensitive to price. If you raise the price, they still buy it because they need it (e.g., petrol or habit-forming goods). Think of a solid brick.

PED and Revenue

This is a "common mistake" area, so watch out!

  • If your product is Inelastic, you should increase the price to make more money (Total Revenue).
  • If your product is Elastic, you should decrease the price to attract way more customers and make more money.

Quick Review: Inelastic = They need it, so charge more! Elastic = They can shop elsewhere, so be careful with price hikes!


7. Income Elasticity of Demand (YED)

This looks at how demand changes when consumer incomes change.

The Formula

\(\text{YED} = \frac{\text{\% change in quantity demanded}}{\text{\% change in income}}\)

Types of Goods

  • Normal Goods (Positive YED): As people get richer, they buy more of these (e.g., designer clothes, holidays).
  • Inferior Goods (Negative YED): As people get richer, they buy less of these (e.g., "value" brand bread or bus travel), because they can now afford the better version (e.g., bakery bread or a car).

Did you know? During a recession (when incomes fall), sales of "luxury" cars might drop, but sales of "home-brand" canned soup often go up! This is YED in action.


Final Summary Checklist

Before you move on, make sure you can:

  • Explain the difference between Mass and Niche markets.
  • Calculate Market Share.
  • Identify why a Demand or Supply curve might shift.
  • Explain why a business would want to know if their product is Price Elastic.
  • Distinguish between a Normal good and an Inferior good using YED.

You've got this! Markets are just the heartbeat of business—once you understand how they pulse, the rest of the course starts to make much more sense.
