Let’s talk about the modern theory of wages—sounds complicated, but it’s really not. Basically, it says wages (that is, what workers get paid) work just like the prices of things we buy. You know how something costs more when it's in demand? Same goes for labour. It’s all about supply and demand—how many people want to work, and how many businesses want to hire.
Where the Demand Comes From
Businesses don’t hire people for fun—they do it because they need work done. That’s where the demand for labour comes in. The more useful or productive a worker is, the more a company wants to hire them. If someone can get a lot of work done, they’re obviously more valuable.
But there’s a limit. Imagine adding too many people to a job—at some point, the extra help doesn’t really add much. That’s called diminishing productivity, and it’s why the demand for labour goes down as wages rise. If workers get too expensive, businesses don’t hire as many. Makes sense, right?
What Affects Labour Demand?
Here are some real-world things that affect how much labour is needed:
1. Technology
New machines and tech can either boost demand (if they make workers more efficient) or cut demand (if they replace people). Depends on the situation.
2. Demand for Products
Labour demand isn’t really about the worker—it’s about what the worker helps produce. If people want a product, companies will hire more workers to make it. If not, hiring slows down.
3. Labour's Role in Production
If only a small number of workers are needed to run machines or processes, companies won’t be hiring in large numbers—even if wages drop. Labour is less “flexible” in that kind of setup.
4. Cost of Other Inputs
If machines or other inputs get cheaper, companies might use those instead of hiring more people. But if machines are expensive, labour demand stays high.
Picture This – A Simple Demand Curve
Imagine a graph:
- Horizontal line (X-axis) = number of workers
- Vertical line (Y-axis) = wage rate Now draw a line that slopes down. That’s your demand curve. It shows that when wages are low, businesses hire more. When wages go up, they cut back.
On the Flip Side: Labour Supply
Now let’s look at the supply of labour—that’s just how many people are willing to work at different wages. This doesn’t just depend on money. Sure, more pay attracts more people, but some might choose free time over extra cash.
There are both economic reasons (like needing more income) and non-economic ones (like family, health, or just wanting a better work-life balance).
Supply Curve: It's Not So Straightforward
For one business, the supply of labour might seem unlimited—they just offer the standard pay and hire as needed. But for an entire industry, things get tricky. To attract more workers, the whole sector may need to raise wages to compete with others.
And here’s the weird part—at some point, if wages go up too much, people might actually choose to work less. Sounds odd, but it's true. If someone’s already earning more than enough, they may decide to enjoy life a bit more and cut back on hours. That’s why the labour supply curve can bend backward at a point.
What Changes Labour Supply?
Let’s break down a few factors that affect how many people are ready to work:
1. Population Size
More people usually means more workers. But it’s not just about how many people exist—it’s about how many are of working age, able, and willing to work.
2. Efficiency
It’s not always about numbers. A smaller group of highly skilled, efficient workers can do more than a big group of undertrained ones. Things like good health, work conditions, and motivation matter a lot.
3. Mobility
If workers can move easily from one place to another (say, from rural to city jobs), supply is more flexible. But if there are barriers—poor transport, language, family ties—then the labour supply becomes limited.
Final Thoughts
So, to sum it up, the modern wage theory says wages are set like any market price—by what employers are willing to pay and what workers are willing to accept. It’s not always simple, though. There are tons of little things—tech changes, lifestyle choices, product demand—that play into it.
It’s not just math and graphs. It’s about real people making decisions about how they want to live, how much they need to earn, and how much companies are willing to offer. That’s what shapes wages in today’s world.
