Economic performance

Welcome to Economic Performance!

In this chapter, we are going to look at the "health check" of a country. Just like a doctor checks your heart rate and temperature, economists check Economic Growth, Unemployment, and Inflation to see how well a nation is doing. These are the big indicators that tell us if the economy is booming or heading for a check-up.

1. Economic Growth and the Economic Cycle

Economic growth is essentially an increase in the amount of goods and services produced in an economy over time. But there are two ways to look at it:

Short-run vs. Long-run Growth

Short-run growth (Actual Growth) is when an economy uses its existing resources more effectively to produce more. Think of this as a factory that is already built but starts running its machines for 12 hours a day instead of 8.
Long-run growth (Potential Growth) is an increase in the productive capacity of the economy. This is like building a whole new factory or inventing a faster machine. On a Production Possibility Diagram, this is shown by the boundary shifting outwards.

The Economic Cycle

Economies don't grow in a straight line; they go through "mood swings" called the Economic Cycle. There are four main phases:

1. Boom: High growth, low unemployment, but high inflation.
2. Recession: Two consecutive quarters (6 months) of negative growth. Unemployment starts to rise.
3. Slump (or Trough): The "bottom" of the cycle. High unemployment and low consumption.
4. Recovery: The economy starts growing again. Confidence returns.

Quick Review: The Cycle Indicators

During a Boom, you will usually see:
- High Real GDP (total output adjusted for inflation)
- High investment from firms
- Rising inflation
- Falling unemployment

Output Gaps

An Output Gap is the difference between the actual level of GDP and the maximum potential level of GDP.
- Positive Output Gap: The economy is growing faster than its "speed limit." This leads to high inflation (the engine is overheating!).
- Negative Output Gap: The economy is producing less than it could. This leads to high unemployment and "spare capacity" (the engine is idling).

Did you know? Economists use the term Animal Spirits (coined by John Maynard Keynes) to describe the human emotions and "gut instincts" that drive the economic cycle. If people feel "bullish" (confident), they spend and the economy grows!

Key Takeaway: Growth can be actual or potential. The economic cycle shows how actual growth fluctuates around the long-term trend, creating booms and recessions.

2. Employment and Unemployment

Being "unemployed" doesn't just mean you don't have a job. In economics, it means you are willing and able to work, and actively seeking a job, but can't find one.

How do we measure it?

The UK uses two main measures:
1. Claimant Count: This counts the number of people claiming unemployment-related benefits (like Jobseeker's Allowance). It’s quick to calculate but can be inaccurate because not everyone who is unemployed is eligible for benefits.
2. Labour Force Survey (LFS): A big survey of households. It follows the International Labour Organisation (ILO) definition. This is usually higher than the claimant count because it includes people who are looking for work but aren't claiming benefits.

Types of Unemployment

Don't worry if these names seem similar; use this memory aid: S.F.S.C. (Super Fast Sports Cars)

- Seasonal: Jobs that only exist at certain times of year (e.g., ski instructors or strawberry pickers).
- Frictional: People who are "between jobs." They have left one and are searching for another. This is usually short-term.
- Structural: A mismatch between the skills workers have and the skills employers need. This happens when industries close down (like coal mining).
- Cyclical (Demand-deficient): This happens during a recession. There isn't enough Aggregate Demand in the economy to justify hiring workers.

The Natural Rate of Unemployment (NRU)

Even when the economy is doing great, unemployment never hits zero. The Natural Rate is the level of unemployment that exists when the labor market is in equilibrium. It consists of frictional and structural unemployment.

Common Mistake to Avoid: Don't confuse voluntary unemployment (choosing not to work at the current wage) with involuntary unemployment (wanting a job at the current wage but not finding one).

Key Takeaway: Unemployment has different causes. Cyclical is caused by the economy slowing down, while structural is caused by changes in the "structure" of the economy itself.

3. Inflation and Deflation

Inflation is a sustained increase in the general price level. It means the value of your money is falling.
Deflation is a sustained decrease in the general price level (prices are going down).
Disinflation is a decrease in the rate of inflation. (Prices are still rising, just more slowly—like a car slowing down but still moving forward).

The Causes: Why do prices change?

1. Demand-Pull Inflation: Too much spending! When "Aggregate Demand" grows faster than the economy can produce goods, prices are "pulled" up.
2. Cost-Push Inflation: Rising costs for firms (like higher oil prices or wages) force them to "push" prices up to protect their profits.
3. Growth of Money Supply: If the government or banks create too much money, the value of each pound drops. This is explained by Fisher's Equation of Exchange:

\( MV = PQ \)

Where:
M = Money Supply
V = Velocity (how fast money changes hands)
P = Price Level
Q = Quantity of goods (Real GDP)

Analogy: If you have 10 apples (Q) and 10 pounds (M), each apple costs 1 pound (P). If the government prints another 10 pounds (making M=20) but there are still only 10 apples, each apple will now cost 2 pounds! That's inflation.

Key Takeaway: Inflation can be caused by too much demand, rising costs, or printing too much money. It reduces the purchasing power of consumers.

4. Conflicts Between Policy Objectives

The government usually wants four things (The "Magic Four"):
1. High Economic Growth
2. Low Unemployment
3. Low and Stable Inflation
4. A Balance of Payments equilibrium

However, it is very hard to get all four at once! This is where Policy Conflicts happen.

The Phillips Curve

This shows the trade-off between Unemployment and Inflation.
- In the Short Run, if the government tries to reduce unemployment (by boosting spending), inflation usually goes up. If they try to stop inflation, unemployment usually goes up.
- In the Long Run, economists (especially Monetarists) believe the Phillips Curve is L-shaped (vertical). This means that in the long run, you cannot reduce unemployment below the "Natural Rate" just by increasing demand; you only end up with higher inflation.

Economic Policies to Reconcile Conflicts

To fix these conflicts, governments might use Supply-Side policies (like education or tax cuts for firms). These can increase growth and reduce unemployment without necessarily causing inflation by shifting the Long-Run Aggregate Supply curve to the right.

Quick Review: Conflicts

- Growth vs. Inflation: Fast growth usually leads to rising prices.
- Growth vs. Environment: More production often leads to more pollution.
- Unemployment vs. Inflation: Falling unemployment often leads to rising wages and prices (The Phillips Curve trade-off).

Key Takeaway: Macroeconomic policy is a balancing act. Fixing one problem (like unemployment) often makes another (like inflation) worse in the short run.
