The Big Question: Who Gets What and How?

Economics is all about choices. Not the "should I get a coffee or a hot chocolate?" kind of choices (although that’s microeconomics in action), but the fundamental, society-shaping decisions about who gets what and how. Why? Yes, you've guessed it, because we live in a world of scarcity - there aren’t enough resources to satisfy everyone’s wants. And that’s where the three big economic questions come in:

  1. What should be produced? Should we invest more in electric vehicles or stick with petrol? Should farmland be used for wheat or avocados? Every society has to decide how to allocate its limited resources.

  2. How should things be produced? Should a factory use thousands of workers or automated robots? Should energy come from coal, wind, or solar?

  3. Who should things be produced for? Should income be evenly distributed, or should those who work the hardest (or are just lucky) get the biggest share?

Economic Systems: Who’s in Charge?

Different economies answer these questions in different ways. Some let markets take control, others rely on the government, and most sit somewhere in between.

The Free Market: Let the People Decide

In a pure free market economy, everything is privately owned, and resource allocation is decided by individuals and businesses in markets. If people want something, businesses will produce it. If it’s profitable to use AI-powered robots instead of workers, companies will make the switch. Prices adjust based on supply and demand - there’s no government interference (at least in theory).

Singapore is one of the closest examples of a free market economy today. With low taxes and minimal government intervention, businesses thrive based on competition and consumer demand. However, even Singapore has public services like healthcare and education, meaning it’s not a pure free market.

Command Economy: The Government Takes the Wheel

At the other end of the spectrum is the command economy (a.k.a. communism or socialism). Here, the government makes all economic decisions: what’s produced, how, and for whom. Private property is limited or non-existent, and prices are set by the state rather than supply and demand.

North Korea operates under a command economy, where the government controls nearly everything, from food distribution to job assignments. While this ensures equality (at least in theory), it often leads to inefficiencies and shortages.

Mixed Economy: A Bit of Both

Most countries today, including the UK, the US, and most of Europe, operate under a mixed economy - a blend of free markets and government intervention. While businesses compete in most sectors, the government provides essential services like education, healthcare, and infrastructure.

The UK has a mixed economy supermarkets and tech companies operate in free markets, but services like the NHS and public transport receive government funding. Even the US, known for its capitalism, has social programmes like Medicare and public schools.

The PPC: What Can We Produce?

To visualise these choices, economists use the Production Possibility Curve (PPC) - a graph that shows the maximum possible output an economy can achieve given its resources.

What the PPC Tells Us (Where can we use the PPC / PPF in IB Economics)

  • Scarcity: The PPC shows that we can’t have unlimited production - resources are limited.

  • Opportunity Cost: Moving production from one good to another means sacrificing something else (e.g., more tanks mean fewer hospitals).

  • Economic Growth: If an economy gets more resources or becomes more efficient, the PPC shifts outward.

  • Economic Development: A country might shift focus from making weapons to producing medical supplies, improving overall well-being.

During the COVID-19 pandemic, many economies shifted their production from consumer goods to medical equipment and vaccines. This was a real-life movement along the PPC, prioritising health over other sectors.

Growth vs. Development: Not the Same Thing!

Many people confuse economic growth and economic development, but they’re different:

  • Economic Growth: An increase in total output (GDP). A country can get richer, but that doesn’t mean life improves for everyone.

  • Economic Development: A broader concept, including improvements in health, education, and living standards.

China has experienced massive economic growth over the past few decades, becoming the world’s second-largest economy. However, we cannot assume this is an indication of economic prosperity, in China, income inequality remains high, and many rural areas still lack access to quality healthcare and education.

Final Thought: Economics Is About People

Whether it’s deciding how to spend a nation’s budget or just choosing between a PlayStation and an Xbox, economics is everywhere. The choices societies make today - whether about AI, climate change, or healthcare - will shape the future. And understanding economics helps us make better decisions, both as individuals and as a society.

So, next time you’re debating whether to splurge on a new gadget or save for a rainy day, remember: you’re not just making a personal choice - you’re participating in the great economic system!
