📖 1. Measuring Growth with GDP

🔑 Key Concepts & Definitions

• Gross domestic product: measures the volume of goods and services produced during a given period

★ Must-know

📌 Nominal GDP is measured at current prices and can overstate growth when prices rise, whereas real GDP removes the price effect to measure changes in production volume.

📐 Formula - The growth rate is calculated as $\frac{V_A-V_D}{V_D}\times100$, where the final value is compared with the initial value.

• GDP does not by itself account adequately for resource depletion, the domestic economy, wealth distribution or inequalities between countries.

Further detail

• GDP per capita comparisons reveal differences between countries in GDP, prices, living standards and development.

💡 Memory Hook

Nominal GDP includes prices, whereas real GDP isolates production volume.

📖 2. Origins of Modern Growth

📝 Essential Points

• For millennia, GDP and living standards remained broadly stagnant before growth accelerated at the beginning of the nineteenth century.

• The modern growth take-off involved:

  • industrial transformation
  • agricultural transformation
  • demographic transformation
  • changing mentalities

• Economic growth can improve material living conditions and contribute to social and demographic development.

💡 Memory Hook

Industrial change → agricultural change → demographic change → new mentalities.

📖 3. Labour and Capital Accumulation

🔑 Key Concepts & Definitions

• Factors of production: are the resources and means used to produce goods and services, especially labour and fixed capital
• Capital: Capital consists of elements used for several years to produce other goods or services, including material assets such as machines and buildings and intangible assets such as patents and software.
• Productive combination: the respective quantity of labour and capital required to produce a given output

📝 Essential Points

• The quantity of labour depends on:
  • population growth
  • net migration
  • annual working time
  • activity rates
  • employment behaviour
  • the distribution of working time

📌 Adding capital without increasing the other factors of production eventually produces diminishing marginal returns, so each additional unit generates a smaller or zero extra gain.

💡 Memory Hook

More labour and capital → greater production capacity → extensive growth.

📖 4. Productivity and Technical Progress

🔑 Key Concepts & Definitions

• Total factor productivity: measures the efficiency with which labour and capital are used in production
• Technical progress: the set of innovations that improves the efficiency of the productive system and allows more or better output with the same quantities of labour and capital

★ Must-know

• In 1957, Robert Solow showed that the quantities of labour and capital explain only part of economic growth.

Further detail

• Process innovations introduce new machines, while organisational innovations change the organisation of tasks.

• Technical progress can proceed from fundamental research to applied research and then to a tested, commercialised innovation adopted in routine production.

💡 Memory Hook

Innovation → productivity gains → higher supply, demand and growth.

📖 5. Endogenous Growth and Institutions

🔑 Key Concepts & Definitions

• Endogenous growth: driven by economic agents’ decisions to produce knowledge and accumulate different forms of capital
• Institutions: Douglas North - formal rules and informal conventions that structure behaviour, reduce uncertainty and organise interactions between individuals and groups
• Property rights: give a person the power to possess, use, sell, give away and receive the benefits of a good

📝 Essential Points

• The four forms of capital are:
  • physical capital
  • technological capital
  • human capital
  • public capital

📌 Inclusive institutions allow broad participation in economic activity, whereas extractive institutions concentrate resources and power among a small elite.

💡 Memory Hook

The four capitals are physical, technological, human and public.

📖 6. Unequal Effects of Technical Progress

★ Must-know

📌 Technical progress can complement workers by raising their productivity, but it can also substitute for workers by automating their tasks.

• Technical progress tends to favour skilled and non-routine workers and can polarise the labour market.

• The unequal diffusion of technical progress contributes to global polarisation between countries specialising in high-value-added activities and countries remaining in low-value-added activities.

Further detail

• Growth and innovation concentrate in metropolitan poles containing dynamic firms, universities and research centres, while other regions may remain on the margins.

💡 Memory Hook

Technology complements some workers but substitutes for others.

📖 7. Ecological Limits of Growth

🔑 Key Concepts & Definitions

• Negative externality: occurs when an activity imposes costs on society that are not fully included in the private decision-maker’s costs

★ Must-know

• Economic growth can deplete renewable resources when they are extracted faster than they regenerate and can exhaust non-renewable resources.

Further detail

• If the whole world consumed like the United States, approximately five planets would be needed.

• Air pollution is caused especially by the combustion of coal, oil and gas and is associated with respiratory, cardiovascular and cancer risks.

• According to the World Health Organization, 98% of the world’s population breathes air containing high levels of fine particles.

💡 Memory Hook

A growing economy draws down a finite natural stock and leaves pollution behind.

📖 8. Innovation and Sustainable Growth

🔑 Key Concepts & Definitions

• Strong sustainability: requires maintaining at least a constant stock of natural capital, especially critical natural capital essential to ecosystem functioning
• Green innovation: improves economic and human well-being while ensuring that natural resources continue to provide necessary goods and services

★ Must-know

📌 Electric vehicles can emit less carbon dioxide over their life cycle than thermal vehicles, but their batteries are difficult to recycle and their production also requires energy and materials.

Further detail

• Public authorities can support ecological innovation through regulation, subsidies and support for equipment such as photovoltaic installations.

💡 Memory Hook

Strong sustainability preserves natural capital, whereas weak sustainability allows substitution.
