📖 1. Creative Destruction and Capitalism

🔑 Key Concepts & Definitions

• Creative destruction : Schumpeter — the process through which new production and activities replace goods and activities made obsolete by technical progress

★ Must-know

📌 According to Schumpeter, creative destruction is inherent to capitalism and continuously renews the productive fabric by destroying old elements and creating new ones.

Further detail

• Online commerce illustrates creative destruction because it develops firms selling online and creates related activities such as delivery, transport, online advertising, and labour-intensive services.

💡 Memory Hook

Old productive elements disappear while new activities emerge.

📖 2. Innovation as Economic Change

🔑 Key Concepts & Definitions

• Innovation : Schumpeter — the industrial or commercial application of an invention or of technical progress within the production system

📝 Essential Points

📌 Innovation can enable an entrepreneur to reduce competition and increase market share by changing the way a product is made or presented on the market.

📌 Innovation initiates creative destruction by replacing the productive fabric and creating new economic activities and outlets.

💡 Memory Hook

Invention applied in production → innovation → productive transformation.

📖 3. Innovation Types and Effects

📝 Essential Points

• Schumpeter identifies four types of innovation:

  • product innovation
  • process innovation
  • organisational innovation
  • market innovation

• The digital camera illustrates product innovation that destroyed activities involving film cameras, photographic film, and in-store photo printing while creating digital cameras, memory cards, accessories, and photo-editing software.

💡 Memory Hook

Product, process, organization, market.

📖 4. Technical Progress and Growth

★ Must-know

📌 Technical progress in the narrow sense consists of innovations in products or production, whereas in the broad sense it includes anything that increases the productivity of the factors of production.

• The course represents the growth mechanism as innovation → technical progress → productivity → economic growth.

Further detail

📌 In Schumpeter's analysis of growth, technical progress is introduced without explaining its origin and is therefore treated as a residual or exogenous element.

💡 Memory Hook

Innovation → technical progress → productivity → economic growth.

📖 5. Sources of Technical Progress

★ Must-know

• The course identifies these sources or forms of technical progress: natural factors, factors of production, machines, sources of raw materials and energy, changes in firms' organisation such as the assembly line

Further detail

• Technical progress can affect the factors of production themselves, machines, new technologies, and the qualification of labour.

• The course observes a positive empirical correlation between technical progress, productivity growth, and economic growth.

📖 6. Productivity and Growth Mechanisms

🔑 Key Concepts & Definitions

• Productivity : measures the efficiency of the productive combination by relating production to the factors used
• Total factor productivity : the increase in production that is not explained by an increase in the factors of production

★ Must-know

📐 Formula — Productivity is calculated as production divided by the quantity of factors used: $P = \frac{\text{production}}{\text{quantity of factors used}}$.

• 🔄 Productivity gains can produce the following effects: higher labour income can increase consumption, lower wages relative to output can increase profits, higher profits can increase investment, lower selling prices can increase purchasing power

Further detail

• When production rises from 100 to 120 units while the quantity of labour remains 10, labour productivity rises from 10 to 12 units per labour unit.

📌 Productivity gains can create economic activity because increased purchasing power and investment support demand for new goods and services.

💡 Memory Hook

Productivity gains → purchasing power, profits, investment, and new activity.

Innovation and its effects

Notion	Main role	Effect
Invention	Creates a new idea or technique	Becomes economically effective only when applied
Innovation	Applies an invention industrially or commercially	Can reduce competition and increase market share
