Economic systems - Economics IGCSE Study Notes

Think of an economic system like the rulebook for how a country decides what stuff to make, how to make it, and who gets to use it. Just like a game needs rules (like football or chess), a country needs rules to manage its economy.

There are three main types of rulebooks, or economic systems:

• Market Economy (or Free Market Economy): Imagine a giant shopping mall where everyone can buy and sell almost anything they want. The prices are set by how much people want something (demand) and how much of it is available (supply). The government doesn't tell businesses what to make or what to charge. It's mostly about individual freedom and competition.
• Command Economy (or Planned Economy): This is like a single, very powerful boss (the government) who decides everything. They tell factories what to produce, how many, and who gets them. There's very little choice for individuals or businesses. The goal is often to make sure everyone gets an equal share, but it can sometimes lead to shortages or things people don't really want.
• Mixed Economy: Most countries today are a bit of both! This is like having a shopping mall (market economy) but with some rules from the government. For example, the government might provide free education or healthcare, or set rules to protect the environment, even though most businesses are privately owned. It tries to get the best of both worlds: efficiency from the market and fairness from government involvement.

Let's use the example of making shoes.

• In a Market Economy (like the USA or UK): A shoemaker sees that many people want trendy new sneakers. They decide to open a factory, hire workers, and buy materials. They set a price based on what other shoemakers charge and what customers are willing to pay. If their shoes are popular, they make a profit. If not, they might go out of business. The government doesn't tell them what kind of shoes to make or how many.
• In a Command Economy (historically, like the old Soviet Union): The government decides that the country needs 1 million pairs of sturdy brown work boots. They tell a state-owned factory to produce exactly that many. They set the price, and everyone gets a pair if they need them. There might not be any trendy sneakers, even if people want them, because the government didn't plan for them.
• In a Mixed Economy (like Canada or Germany): Most shoe companies are private businesses, just like in a market economy. They compete and innovate. However, the government might set rules about worker safety in shoe factories, or make sure the materials used aren't harmful to the environment. They might also provide unemployment benefits for shoemakers who lose their jobs if a factory closes.
