4.3.2 Productivity And Determinants Of Economic Growth
Introduction
Economists use the term productivity to describe output (e.g., GDP) per unit of input (e.g., the labor and capital used to produce the goods and services). Increased productivity means more is produced with less expenditure, creating a net benefit for the economy. This concept closely ties with GDP (Gross Domestic Product) and is essential for understanding economic growth.
In this section, we will explore how productivity is related to economic growth by examining key factors such as technological advances, population growth, and improvements in training, education, and skills.
Key Determinants of Economic Growth
Growth in GDP is influenced by various elements, but specific key factors contribute significantly to productivity gains. Let’s delve deeper into these:
1. Technological Advances
Technological progress is one of the main engines of growth. New technologies can make production processes more efficient and create new products and services.
- Example: The advent of the internet has revolutionized many industries and led to significant productivity increases.
2. Population Growth
An increase in population can contribute to economic growth by expanding the labor force. However, it is crucial that this increase is coupled with employment opportunities to be beneficial.
- Example: Countries with rapidly growing populations such as India can leverage their large workforce to boost productivity.
3. Improvements in Training, Education, and Skills
Investing in human capital—through education, training, and skill development—is critical. A more educated and skilled workforce can adopt new technologies more rapidly and perform tasks more efficiently.
- Example: Nations like South Korea have shown rapid economic growth largely due to heavy investments in education.
Frequently Asked Questions (FAQs)
Q: How does productivity impact GDP?
A: Productivity impacts GDP by allowing for the production of more goods and services at a lower cost and greater efficiency, which contributes to overall economic growth.
Q: Why are technological advances crucial for productivity and economic growth?
A: Technological advances improve the efficiency of production processes, create new products, and facilitate new markets, directly contributing to productivity increases and, subsequently, economic growth.
Key Takeaways
- Productivity is defined as output per unit of input and is essential for measuring economic efficiency.
- GDP growth is closely linked with productivity improvements.
- Key factors influencing productivity include technological advances, population growth, and investments in human capital.
Conclusion
Understanding productivity and its determinants is crucial for driving economic growth. By focusing on technological advancements, managing population growth effectively, and investing in education and skills development, economies can enhance their productivity, thereby generating wealth and improving overall economic conditions.
Glossary
- Productivity: The efficiency with which inputs are converted into outputs.
- Gross Domestic Product (GDP): The total value of goods and services produced within a country’s borders in a specific time period.
- Human Capital: The attributes gained by individuals through education, training, and experience that increase their value in the workforce.

## What does the term 'productivity' describe in economic terms?
- [ ] Consumption per unit of input
- [x] Output per unit of input
- [ ] Income per unit of input
- [ ] Savings per unit of input
> **Explanation:** Economists use the term productivity to describe the output (e.g., GDP) per unit of input (e.g., labour and capital used to produce goods and services). An increase in productivity means more production with less expenditure.
## Which of the following is an example of a productivity increase?
- [ ] More input with more output
- [ ] Less input with less output
- [x] More output with the same amount of input
- [ ] Same output with decreasing input
> **Explanation:** A productivity increase is when more output is achieved with the same or fewer inputs, resulting in a net benefit for the economy.
## Which factor is NOT a key contributor to productivity gains?
- [ ] Technological advances
- [ ] Population growth
- [ ] Improvements in training, education, and skills
- [x] Increase in consumption
> **Explanation:** The key factors that contribute to productivity gains include technological advances, population growth, and improvements in training, education, and skills. Increased consumption does not directly contribute to productivity gains.
## How does growth in real GDP typically relate to productivity?
- [ ] Growth in real GDP always decreases productivity
- [ ] Growth in real GDP is unrelated to productivity
- [x] Growth in real GDP is often linked to productivity gains
- [ ] Growth in real GDP is inversely related to productivity
> **Explanation:** Growth in real GDP and productivity gains are often linked. As productivity increases, it allows more to be produced with less expenditure, contributing to GDP growth.
## Why is population growth a contributing factor to GDP growth?
- [ ] It decreases the demand for goods and services
- [ ] It reduces the labour supply
- [ ] It increases the amount of capital available
- [x] It increases the labour supply and potential consumer market
> **Explanation:** Population growth increases the labour supply and the potential consumer market, which can contribute to GDP growth.
## Which of the following is a direct benefit of improving education and skills?
- [ ] Increase in interest rates
- [x] Increase in productivity
- [ ] Decrease in technological advances
- [ ] Decrease in GDP
> **Explanation:** Improvements in education and skills directly lead to increased productivity as workers become more efficient and capable.
## What is the ultimate goal in achieving productivity gains?
- [ ] Reducing the workforce
- [ ] Increasing input use
- [x] Producing more with less expenditure
- [ ] Increasing consumption
> **Explanation:** The ultimate goal of productivity gains is to produce more output with less expenditure of inputs, thereby creating a net economic benefit.
## Which statement best describes the relationship between technological advances and productivity?
- [ ] Technological advances increase labour costs
- [x] Technological advances improve productivity
- [ ] Technological advances reduce GDP
- [ ] Technological advances decrease output
> **Explanation:** Technological advances improve productivity by allowing more efficient production processes, resulting in more output with the same or fewer inputs.
## What impact does improvement in training have on an economy?
- [ ] It lowers the GDP
- [ ] It reduces the labour supply
- [ ] It decreases productivity
- [x] It increases productivity
> **Explanation:** Improvement in training enhances the skills of workers, making them more efficient, thereby increasing productivity.
## Which of the following best contributes to making nations wealthier?
- [ ] Decrease in real GDP
- [ ] Reduction in labour supply
- [x] Gains in productivity
- [ ] Increase in consumption
> **Explanation:** Gains in productivity contribute to making nations wealthier as they allow for more efficient use of resources, leading to increased output and economic growth.
