Positive vs Normative Statements
You'll encounter two types of economic statements that are crucial to distinguish. Positive statements are about "what is" - they're factual claims based on evidence and economic theory that can be tested or proven. Think of them as the objective, scientific side of economics.
Normative statements are about "what should be" - they involve personal opinions and value judgements. These reflect what someone believes ought to happen, not what actually happens.
Here's the key difference: saying "raising alcohol taxes will reduce alcohol consumption" is positive (it's based on economic theory), but saying "the government should raise alcohol taxes" is normative (it's an opinion about what's right).
Remember: Positive = provable facts, Normative = personal opinions
The Basic Economic Problem
Here's the fundamental issue that drives all of economics: we live in a world of unlimited wants but limited resources. This creates scarcity, which forces everyone - individuals, businesses, and governments - to make choices about how to use what they have.
Think about your own life. You probably want loads of things but have a limited budget, so you constantly choose between spending on different items. This same principle applies everywhere, from governments choosing between hospitals and schools to businesses deciding what products to make.
Scarcity leads to three key questions every society must answer: What to produce? How to produce it? For whom should we produce it? These aren't just theoretical - they shape real decisions that affect your daily life.
Key insight: Even wealthy countries face scarcity because human wants are truly unlimited - there's always something more we desire.
Understanding Scarcity in Practice
Scarcity isn't just about extreme poverty (though that's certainly an example). Even if you live comfortably in the UK, you still experience scarcity because your wants exceed your resources. You might want the latest iPhone, designer clothes, holidays abroad, and a car - but your income limits what you can actually have.
This connects to human nature itself. Philosophers and economists have noted that people don't just want to be wealthy - they want to be wealthier than others. This explains phenomena like "keeping up with the Joneses" where people constantly want better things than their neighbours.
The economic problem affects everyone differently, but it affects everyone. Whether you're choosing between a sandwich and a drink at lunch, or a government is choosing between funding cancer drugs or surgical equipment, it's all the same underlying issue.
Reality check: Your wants really are unlimited - just think about how your wish list keeps growing even when you get things you wanted.
Economic vs Free Goods
Not everything in our world is scarce. Economic goods are scarce relative to demand, which means consuming them involves an opportunity cost - the benefit you give up from the next best alternative. Most things you buy are economic goods because there isn't enough for everyone to have as much as they want.
Free goods, on the other hand, are abundant enough that consuming them doesn't prevent others from consuming them too. Air is the classic example - you breathing doesn't stop others from breathing.
The key distinction is opportunity cost. When you choose to spend money on something, you're giving up the chance to spend that money on something else. That's the opportunity cost, and it only applies to economic goods.
Test tip: If a good has an opportunity cost when consumed, it's an economic good. If not, it's a free good.
The Four Factors of Production
Every good or service you've ever consumed was made using some combination of four factors of production. Understanding these helps explain how our economy actually creates the things we need and want.
Land includes all natural resources - not just soil, but oil, minerals, forests, rivers, and even climate. Labour is human effort, from manual work to brain surgery to professional football. Capital means goods created to make other goods - machinery, factories, computers, even schools (but not money itself).
Enterprise is the special factor that brings everything else together. Entrepreneurs take risks, start businesses, and organize the other factors to create products profitably. Without enterprise, the other factors would just sit there unused.
Different products need different combinations of these factors. A box of vegetables needs lots of land and labour but little capital, while a car needs massive amounts of capital and relatively less land.
Remember: Capital in economics means physical things that help produce other goods, not money or financial assets.
Rewards to Factors of Production
Each factor of production earns a reward for contributing to the production process, and these rewards have specific names. Labour earns wages or salaries - this is why you get paid for your part-time job. The more skilled you are, the higher wages you can command.
Land earns rent - payments for the use of natural resources. Capital earns interest - the return on physical assets used in production. Enterprise earns profit - the reward for taking risks and successfully organizing production.
These factor incomes explain how wealth gets distributed in the economy. Your family's income comes from providing one or more factors of production to businesses that need them.
Connect the dots: Your wages are the economy's way of rewarding you for providing labour - the more valuable your contribution, the higher your potential earnings.
