Unemployment: More Than Just Numbers
Hello everyone! Welcome to your study notes for "Unemployment". This might sound like a heavy topic, but don't worry, we're going to break it down into simple, easy-to-understand pieces.
Understanding unemployment is super important because it's not just a number you see on the news. It affects real people, their families, and the health of the entire Hong Kong economy. In this chapter, we'll learn how to define and measure unemployment, understand its various types, and examine why it's a major concern for everyone. Let's get started!
1. Who's Who in the Labour Market?
Defining the Key Players
Before we can calculate the unemployment rate, we need to be crystal clear about who we are talking about. Think of it like a sports team – you need to know who is on the team (in the labour force) and who is sitting on the bench (unemployed) to understand the game.
Who is considered "Unemployed"?
In economics, the definition is quite specific. An unemployed person is someone who wants a job but has failed to find one.
For example, Chan Tai Man just graduated from university. He is actively applying for accounting jobs and going to interviews every week, but he hasn't been hired yet. Chan Tai Man is unemployed.
Important: Someone who is NOT working is NOT automatically unemployed. A student focusing on their DSE studies or a retired person enjoying their free time are not considered unemployed because they are not looking for a job.
What about the "Underemployed"?
This is a slightly different situation. An underemployed person is someone who is involuntarily working less than specified working hours. The key word here is involuntarily – it means they want to work more, but they can't find the hours.
For example, Siu Fun is a trained chef who wants a full-time job (around 40 hours a week). However, due to a slow economy, she can only find a part-time job at a cafe for 18 hours a week. She is actively looking for a full-time position. Siu Fun is underemployed.
What is the "Labour Force"?
This is the total pool of people available for work in an economy. It's a simple calculation:
\(\text{Labour Force} = \text{Number of Employed People} + \text{Number of Unemployed People}\)
The labour force includes everyone who either has a job or is actively looking for one. People who are not in the labour force include full-time students, homemakers (who aren't seeking paid work), retirees, and people unable to work.

Unemployed: Wants a job, can't find one.
Underemployed: Has a job, but involuntarily works fewer hours than desired.
Labour Force: Employed + Unemployed. The total "team" of available workers.

2. Measuring the Problem
Putting a Number on It: The Rates
Economists and governments use rates (percentages) to measure unemployment and underemployment. This makes it easy to compare the situation over time or between different countries. Don't worry if maths isn't your strong suit – the formulas are very logical!
The Unemployment Rate
This is the most common measure you'll hear about. It tells us the percentage of the labour force that is currently unemployed.
Here's the step-by-step logic:
1. Find the number of people who are unemployed.
2. Find the total number of people in the labour force.
3. Divide the number of unemployed by the labour force, then multiply by 100 to get a percentage.
The formula is:
\(\text{Unemployment Rate} = \frac{\text{Number of Unemployed}}{\text{Labour Force}} \times 100\%\)
Example: Imagine an economy has a labour force of 5,000,000 people. Among them, 200,000 people are unemployed.
The unemployment rate would be: \(\frac{200{,}000}{5{,}000{,}000} \times 100\% = 4\%\).
The Underemployment Rate
This works in exactly the same way, but instead of counting the unemployed, we count the underemployed.
\(\text{Underemployment Rate} = \frac{\text{Number of Underemployed}}{\text{Labour Force}} \times 100\%\)
Example: In the same economy with a labour force of 5,000,000, let's say 100,000 people are underemployed.
The underemployment rate would be: \(\frac{100{,}000}{5{,}000{,}000} \times 100\% = 2\%\).
Common Mistakes to Avoid!
Mistake #1: Dividing by the total population. ALWAYS divide by the labour force. Remember, a baby or a retiree can't be unemployed, so we don't include them in the main calculation!
Mistake #2: Thinking anyone without a job is "unemployed". Remember the definition: they must be actively looking for a job to be counted as unemployed.
3. Types of Unemployment
Why Do People Become Unemployed?
Unemployment occurs for different reasons. In HKDSE Economics, we classify unemployment into four major types:
1. Frictional Unemployment
This occurs when workers are in the process of moving between jobs or looking for their first job. It takes time for job seekers to find suitable employers and for employers to find suitable candidates because information in the job market is imperfect.
Example: A recent university graduate spending two months attending interviews before accepting a job offer.
2. Structural Unemployment
This arises due to a mismatch between the skills possessed by workers and the skills demanded by employers, often caused by changes in technology or the economic structure.
Example: Workers in traditional manufacturing losing jobs when factories relocate or automate, while vacancies in information technology go unfilled because the displaced workers lack required technical skills.
3. Seasonal Unemployment
This occurs when the demand for certain types of labour fluctuates systematically with the seasons of the year or weather conditions.
Example: Lifeguards at outdoor swimming pools or temporary retail staff hired exclusively for Christmas/Lunar New Year shopping seasons.
4. Cyclical Unemployment (Demand-deficient Unemployment)
This happens when there is an aggregate demand deficiency during an economic recession or downturn. When overall spending in the economy falls, firms reduce production and lay off workers.
Example: A decline in overall consumer spending during an economic crisis leading restaurants and hotels to cut staff.
Natural Rate of Unemployment and Full Employment
Natural Rate of Unemployment: The unemployment rate that exists when the economy is at full employment output (\(Y_f\)). It consists of frictional, structural, and seasonal unemployment, but zero cyclical unemployment.
Full Employment: Full employment does not mean 0% unemployment. In any dynamic economy, there will always be people transitioning between jobs or undergoing structural adjustments.
4. Unemployment and the Whole Economy
Output Gaps: Is the Economy Underperforming or Overheating?
The unemployment rate gives us a powerful clue about how the entire economy is performing. We can compare the economy's actual equilibrium output (\(Y\)) to its potential full employment output (\(Y_f\)). The difference is called an "output gap".
Deflationary (Output) Gap
This happens when the equilibrium output is LESS than the full employment output (\(Y < Y_f\)).
In simple terms: The economy is running below its potential. It's like a powerful sports car stuck in slow-moving traffic.
• There is an excess supply of labour. This means there are more people looking for jobs than there are jobs available.
• This leads to high unemployment (specifically, positive cyclical unemployment).
• Businesses have unused factory space and resources are sitting idle.
Memory Aid: A deflationary gap is a downturn, leading to depressed economic activity and people feeling down.
Inflationary (Output) Gap
This is the opposite situation. It happens when the equilibrium output is GREATER than the full employment output (\(Y > Y_f\)).
In simple terms: The economy is overheating. It's producing at an unsustainable rate, like sprinting the first part of a marathon.
• There is an excess demand for labour. This means firms are eager to hire workers, but there are very few available.
• This means very low unemployment (the actual unemployment rate falls below the natural rate of unemployment).
• To attract the few available workers, firms have to offer higher wages, which can push prices up (inflation).
5. Why We Care So Much
The High Cost of Unemployment
Unemployment is a major problem because its effects are serious and widespread, hurting both individuals and the country as a whole.
Costs to the Unemployed (The Individual)
For the person without a job, the consequences are direct and often painful.
- Loss of income: This is the most obvious cost. Without a salary, it's hard to pay for housing, food, and other necessities. The standard of living falls.
- Loss of skills: When you're out of work for a long time, your job skills can become rusty or outdated. This is especially true in fast-changing industries like technology. This makes it even harder to find a job later on.
- Psychological costs: Losing a job can lead to a loss of self-esteem, stress, anxiety, and depression. It affects a person's mental well-being and their family.
Costs to Society (The Big Picture)
When many people are unemployed, the entire economy suffers.
- Loss of output (GDP): This is the biggest economic cost. Unemployed people are not producing goods or services. This means the total output of the economy (its GDP) is lower than its potential. The nation as a whole is poorer. This is the real-world consequence of a deflationary gap.
- Increased government spending: The government has to spend more money on social welfare and unemployment benefits (like the Comprehensive Social Security Assistance, CSSA, in Hong Kong) to support those without an income.
- Lower tax revenue: Fewer people working means less income for the government from salaries tax. Businesses that are struggling may make less profit, leading to lower profits tax revenue. This gives the government less money to spend on public services like hospitals, schools, and infrastructure.
- Social problems: Areas with very high and long-term unemployment can sometimes experience increases in crime and social unrest.
Key Takeaway
The costs of unemployment are severe for both the individual (loss of income, skills, and well-being) and for society (lost GDP, strain on government finances, and potential social problems). This is why keeping unemployment low is a key goal of economic policy.
