Labour market demand/supply - Microeconomics AP Study Notes
Overview
Have you ever wondered why some jobs pay a lot and others pay less? Or why it's easy to find a job in some areas but really hard in others? It all comes down to something called the **labour market**! Just like there's a market for toys or snacks, there's a market for people's work, skills, and time. In this market, **businesses are the buyers** (they 'demand' workers) and **people are the sellers** (they 'supply' their work). The price in this market isn't for a toy, but for your time and skills – we call that your **wage** (how much you get paid per hour or per year). Understanding how this market works helps us see why certain jobs are in high demand, why wages change, and how different events can affect who gets hired and for how much. It's super important for understanding the economy and even your own future job prospects!
What Is This? (The Simple Version)
Imagine you want to hire someone to mow your lawn. You're looking for someone to do a job, right? That's like demand for labour – businesses (or you) wanting to hire workers. Now, imagine your friend wants to earn some extra money by mowing lawns. They are offering their time and effort. That's like supply of labour – people offering their skills to work.
Think of it like a lemonade stand. The people who want lemonade are the 'demanders,' and the kids selling lemonade are the 'suppliers.' In the labour market:
- Demand for Labour: This is how many workers businesses want to hire at different wages. If wages are low, businesses might want to hire more people. If wages are high, they might want to hire fewer.
- Supply of Labour: This is how many people are willing and able to work at different wages. If wages are high, more people might want to work. If wages are low, fewer people might be interested.
Just like with lemonade, the 'price' (which is the wage in the labour market) will settle where the number of people wanting to work matches the number of jobs businesses want to fill. This is called equilibrium.
Real-World Example
Let's think about the market for video game developers.
Imagine a few years ago, not many people played video games, so not many companies needed game developers. The demand for labour (developers) was low. Because of this, the wages for game developers weren't super high, and maybe not a lot of people chose to study game development in college (low supply of labour).
Now, fast forward to today! Everyone plays video games – on phones, consoles, computers. Suddenly, tons of companies want to make new games. The demand for labour (game developers) has skyrocketed! Companies are desperate to hire talented people.
What happens? To attract enough people, companies start offering much higher wages. This higher wage then encourages more people to go to school to learn game development, increasing the supply of labour over time. It's a constant dance between how many companies want workers and how many people are willing to do the work.
How It Works (Step by Step)
Let's break down how wages and employment are determined in a simple labour market. 1. **Businesses want workers:** Companies decide how many people they need based on how much money those workers can help them make. This is their **demand for labour**. 2. **People want jobs:** Individuals decide ...
