‘The difference between invention and innovation; technological change can affect methods of production, productivity, efficiency and firms’ costs of production.’
Introduction
Technological change plays a vital role in modern economies, shaping production processes, improving efficiency, and altering cost structures. Understanding invention, innovation, and their production effects is essential.
Invention and Innovation
Invention
Invention is the process of creating something entirely new that did not exist before, often through scientific research or experimentation.
Invention: The development of a new idea, product, or process that has not previously existed.
Inventions may arise from advances in science or engineering and are often the foundation for further economic progress. For example, the invention of the microchip transformed global production possibilities.
Innovation
Innovation is distinct from invention. It involves taking an existing idea or invention and applying it commercially to improve products or processes.
Innovation: The application of new ideas or inventions into practical, marketable products, services, or production methods.
Innovation bridges the gap between scientific discovery and economic application, ensuring inventions are not just theoretical but also useful to firms and consumers.
Types of Innovation
Product Innovation
Involves introducing new or improved goods and services.
Example: Smartphones evolving with new features such as facial recognition or 5G capability.
Process Innovation
Concerns improvements in production methods, increasing efficiency and lowering costs.
Example: The use of robotics in car manufacturing assembly lines.
Organisational Innovation
Refers to changes in management structures or business models that improve firm efficiency.
Example: Adoption of digital platforms for supply chain management.
Production Effects of Technological Change
Technological change can have significant effects on methods of production, productivity, and efficiency.
Changes in Methods of Production
Automation reduces reliance on labour and increases the role of capital inputs.
Adoption of advanced machinery allows firms to shift towards mass production.
Use of AI and machine learning improves precision and reduces error in manufacturing.
Productivity Impacts
Productivity refers to the efficiency with which inputs are converted into outputs.
Productivity: The output produced per unit of input, often measured as output per worker or per hour worked. The output produced per unit of input, often measured as output per worker or per hour worked.
Technological progress typically raises labour productivity, enabling each worker to produce more in less time.
Capital productivity can also improve, as better machines generate greater output from the same resource base.
Understanding the adoption process is essential for firms to strategise effectively.

Efficiency Gains
Technical efficiency: Firms use fewer inputs for the same output.
Allocative efficiency: Innovation ensures resources are directed towards producing goods most valued by society.
Reductions in average costs of production strengthen competitiveness.
Cost Implications for Firms
Technological change often reshapes the cost structures of firms.
Fixed costs may rise due to investment in new technology (e.g., machinery, software).
Variable costs may fall as production becomes more efficient and labour needs decline.
Long-run average costs (LRAC) can shift downward with process innovations, enabling firms to exploit economies of scale.
For example, the introduction of 3D printing reduces material wastage, lowering variable costs while creating opportunities for new business models.
Technological change can expand the production capacity of an economy.

Wider Economic Effects
Increased Competitiveness
Firms adopting innovation can achieve a first-mover advantage, securing higher profits before rivals catch up.
Export potential increases as costs fall and productivity rises, improving balance of payments performance.
Structural Changes
Entire industries may be reshaped.
Technological change can lead to creative destruction, where old industries decline as new ones emerge (e.g., streaming services replacing DVD sales).
Labour Market Impacts
Increased demand for skilled labour to manage advanced technologies.
Potential for structural unemployment if workers cannot adapt to new processes.
Opportunities for higher wages in innovative sectors.
Key Points to Remember
Invention creates new ideas, while innovation applies them to production and markets.
Technological change affects methods of production, productivity, efficiency, and costs.
Product and process innovations are central to economic growth and competitiveness.
Firms must weigh higher fixed costs against potential long-term savings and efficiency gains.
The broader economy experiences shifts in industry structure, employment patterns, and competitiveness.
FAQ
Patents give inventors exclusive rights to their creations for a set period, allowing them to profit without immediate competition. This encourages investment in new ideas.
By protecting returns, patents reduce the risk of financial loss. However, they can also create temporary monopolies, which may limit the spread of beneficial innovations until the patent expires.
Innovation can reshape industries by lowering costs, creating new products, or disrupting existing markets.
If many firms adopt similar innovations, competition may increase.
If a single firm controls key technology, it may gain monopoly power.
Over time, innovation can lead to consolidation, as efficient firms drive weaker competitors out.
Innovation often requires large upfront spending on research, machinery, or training. This raises fixed costs with no guarantee of success.
Firms may fear that rivals will imitate innovations quickly, eroding any competitive advantage. Risk-averse businesses may therefore prefer incremental improvements rather than radical changes.
Incremental innovation involves small, continuous improvements to existing products or processes, such as adding features to a smartphone.
Radical innovation introduces a completely new product or process, such as the first electric car or the development of streaming platforms. Radical innovations are riskier but can bring major competitive advantages.
Innovation can improve consumer welfare by increasing product variety, enhancing quality, and reducing prices through efficiency gains.
Consumers also benefit from improved accessibility, such as online shopping platforms or telemedicine services. However, rapid innovation may create adjustment costs, as older products become obsolete quickly, forcing consumers to adapt.
Practice Questions
Define the term innovation and explain briefly how it differs from invention. (3 marks)
