Speaker notes: Title slide.
Learning Objectives
- Define economic growth
- Explain how economic growth is measured
- Analyse causes and consequences of economic growth and recession
- Evaluate policies to promote economic growth
Speaker notes: List the learning objectives for the lesson.
Starter: Discussion
- Imagine a country where people's incomes are rising, jobs are available, and new factories are being built. What might be causing this?
Speaker notes: Encourage students to think about the factors that contribute to economic growth.
Definition of Economic Growth
- Increase in real GDP over time
- More goods and services produced
- Rising living standards
Speaker notes: Explain that economic growth is not just about more money but about producing more goods and services, which can lead to better living standards.
Measurement of Economic Growth
- Measured by real GDP
- Adjusted for inflation
- Compares different time periods
Speaker notes: Emphasise the importance of using real GDP to measure economic growth, as it accounts for inflation and allows for comparisons over time.
Causes of Economic Growth
- Increased investment in capital
- Improvements in technology
- Increase in labour force
- Better education and training
Speaker notes: Discuss how each of these factors can contribute to economic growth.
Consequences of Economic Growth
- Higher living standards
- More jobs
- Increased government revenue
- Environmental impact
Diagram explained
This diagram shows a production possibility curve (PPC) with an outward shift. The original PPC represents the maximum production of two goods, capital goods and consumer goods, with scarce resources. The outward shift shows economic growth, which allows the economy to produce more of both goods. This growth can be caused by factors such as increased investment, technological advancements, or a larger labour force.
- Start with the original PPC.
- Identify the shift to the new PPC.
- Note the increase in production possibilities.
Speaker notes: Highlight both the positive and negative consequences of economic growth.
Causes of Recession
- Decrease in aggregate demand
- Fall in investment
- Negative shocks (e.g., natural disasters)
- High interest rates
Speaker notes: Explain how each of these factors can lead to a recession.
Consequences of Recession
- Lower living standards
- Higher unemployment
- Decreased government revenue
- Business closures
Speaker notes: Discuss the negative impacts of a recession on the economy and its people.
Policies to Promote Economic Growth
- Fiscal policy (e.g., tax cuts, increased government spending)
- Monetary policy (e.g., lowering interest rates)
- Supply-side policies (e.g., education, infrastructure)
- Free trade agreements
Speaker notes: Explain how each of these policies can stimulate economic growth.
Worked Example: Economic Growth
- Country A's real GDP in 2020: 100 billion
- Country A's real GDP in 2021: 105 billion
- Calculate the economic growth rate: ((105 - 100) / 100) x 100 = 5%
Speaker notes: Show students how to calculate the economic growth rate using real GDP data.
Common Mistakes and Exam Tips
- Mistake: Confusing nominal GDP with real GDP
- Tip: Always adjust for inflation when measuring economic growth
- Mistake: Ignoring the environmental impact of economic growth
- Tip: Discuss both positive and negative consequences in your answers
Speaker notes: Highlight common mistakes students make and provide tips for the exam.
