Outline of unit topics:
A. Introduction
B. Inequality
C. "Hockey stick" growth
D. Capitalism
E. Capitalism and the hockey stick growth
Key backdrop: rapid, sustained growth in living standards since 1700 and the questions surrounding why this happened, including technology, institutions, and policy.
B. Inequality
Reading focus: UNIT 1 SECTIONS 1.1–1.2.
What is meant by inequality?
Between-country inequality: The average income or quality of life in one country vs another. large differences in average incomes across countries today vs. the past.
Within-country inequality: Rich vs poor inside one country. differences in incomes within a country.
Data highlights (illustrative examples):
Singapore (richest country on the right in the data):
richest 10%:
poorest 10%:
Liberia (on the left):
richest 10%:
poorest 10%:
Data points available for years: (Source: coreecon).
Historical context:
Around 1,000 years ago the world was effectively “flat” in income levels; today there are large disparities across countries.
The growth of between-country inequality is linked to the hockey stick pattern discussed in section C.
Inequality and growth: long periods with no sustained growth; when growth did occur, it started at different times across places.
Early takers of growth (e.g., UK, Japan, Italy) are now relatively rich.
Some countries experienced growth only recently or not at all, remaining in the “flatlands.”
Measuring income and living standards:
Gross Domestic Product (GDP): (conceptual definition)
GDP per capita ≈ average income; commonly used metric, but has limitations.
Disposable income:
GDP is an imperfect measure of wellbeing but correlates with other wellbeing indicators (e.g., life expectancy at birth, infant mortality rate).
C. "Hockey stick" growth
Reading focus: UNIT 1 SECTIONS 1.3–1.5.
What is a "hockey stick" growth curve?
Represents sustained rapid growth in GDP per capita across many countries.
Timing of growth take-offs:
Britain: around 1650
Japan: around 1870
China and India: kink in the second half of the 20th century
In some economies, substantial improvements in living standards did not occur until independence from colonial rule or European interference.
The Technological Revolution (as part of the hockey stick story):
Technology = process that uses inputs to produce outputs; reduces the time-work required to obtain goods and services.
Technological advances occurred roughly contemporaneously with the upward kink in Britain in the middle of the 18th century.
Time scarcity and technology:
Time is a scarce resource: to allocate between work and leisure.
Technological changes ease the work-leisure trade-off, allowing either:
more leisure time for the same amount of work, or
more consumption for the same amount of work.
Industrial Revolution:
Definition: a wave of technological advances starting in Britain in the 18th century that transformed an agrarian/craft-based economy into a commercial/industrial economy.
Example of productivity gain: today the productivity of labour in producing light is about times greater than at our ancestors’ campfires.
A connected world:
Technological progress greatly increased the speed of information transfer, making the world more connected.
Environmental consequences:
With more production and population growth come global impacts (climate change) and local impacts (urban pollution, deforestation).
Technology may help solve environmental problems by enabling more output with fewer resources.
Overall logic:
The hockey stick growth reflects a combination of rapid productivity improvements through technology and the organization of production (markets, specialization) that together raised living standards.
D. Capitalism
Reading focus: UNIT 1 SECTIONS 1.6–1.8.
Capitalism: what it is
Institutions are the laws and social customs that govern production and distribution.
Capitalism = an economic system where the main institutions are private property, markets, and firms.
Key concepts defined:
Private property:
Ownership rights over possessions.
Capital goods = non-labour inputs used in production.
Note: private property does not include some essentials (e.g., air, knowledge).
Markets:
A way for people to exchange products and services for mutual benefit.
Characteristics: reciprocal transfers, voluntary, usually competitive.
Firms:
Business organization that uses inputs to produce outputs and sets prices to at least cover production costs.
Inputs and outputs are private property.
Firms use markets to sell outputs.
Aim is to make a profit, which provides incentives to innovate and adopt new technologies (evident during the Industrial Revolution).
The Capitalist Revolution: why capitalism helped raise living standards
Impact on technology: firms in competitive markets had strong incentives to adopt/develop new technologies.
Specialisation: growth of firms and expanded markets linked the world, enabling unprecedented specialization of tasks and production.
Together with the technological revolution, these factors increased worker productivity.
The gains from specialization:
Specialisation increases productivity because people focus on a limited range of activities (learning by doing, leveraging natural skill differences, economies of scale).
For specialization to work, people must obtain the other goods they need through markets.
Comparative advantage (example):
Greta has absolute advantage in producing both crops, but Greta has a comparative advantage in wheat, while Carlos has a comparative advantage in apples.
Production possibilities given full-time effort:
Greta: 1250 apples or 50 tonnes of wheat
Carlos: 1000 apples or 20 tonnes of wheat
Implication: All producers can benefit by specializing and trading, as markets increase labour productivity via specialization.
Comparative advantage takeaway:
Even if one producer is worse at producing both goods (in absolute terms), there can be gains from trade through specialization based on comparative advantage.
E. Capitalism and "hockey stick" growth
Central question: Did capitalism cause the hockey stick growth?
Natural experiment referenced: division of Germany after World War II into capitalist (West) and centrally planned (East) systems.
The question invites comparing growth outcomes under different institutional arrangements.
Variability in capitalist economies:
Not all capitalist economies succeed equally; incentives matter.
The role of economic conditions: firms, private property, and markets may fail in some contexts.
The role of political conditions: capitalist institutions are often regulated by government; governments provide essential goods and services (infrastructure, education).
These factors can explain divergence in growth across countries.
Political systems and capitalism:
Capitalism coexists with many political systems; in most countries today, capitalism coexists with democracy (individual rights, free elections).
capitalism has also coexisted with non-democratic regimes.
Summary: key takeaways from the unit
1) Important trends in economic variables over time:
Income inequality across regions has increased over time.
The hockey stick pattern in GDP per capita is a defining feature of modern economic history.
Technological progress helped drive these trends.
2) The adoption of capitalism is a major factor:
Capitalism defined as Private property + Markets + Firms.
Failures or weaknesses in these institutions can explain divergence in growth across countries.
Political systems and the role of government shape the type of capitalist society that emerges.
Additional note on government role (interwoven with section D and E): Government action matters for incentives, regulation, infrastructure, education, and overall policy environment that can support or hinder capitalist growth.
Summary cross-cutting points
The evolution of economic growth hinges on:
Technological progress and the ability to implement and diffuse new technologies.
The organization of production via markets and firms, and the incentives created by private property rights.
Institutions and policy environments that support or hinder specialization, trade, and innovation.
The balance between growth incentives and government provisions (infrastructure, education, regulation).
The data and examples highlighted (income distribution, take-off timings, production frontiers) illustrate the complexity of growth and the reasons why some regions pulled ahead while others remained in the so-called flatlands for longer periods.
Key formulas and data points to remember
Disposable income:
GDP per capita is a common proxy for living standards, but it is not a perfect measure of wellbeing.
GDP is conceptually: (definition, not a single formula used in the lecture, but a reminder of its meaning).
GDP per capita relationship (conceptual): (they measure different concepts).
Comparative advantage data example:
Greta: 1250 apples or 50 tonnes of wheat
Carlos: 1000 apples or 20 tonnes of wheat
Implication: Specialization allows gains from trade through different opportunity costs.
Productivity upgrade example during Industrial Revolution:
Labour productivity in producing light today ≈ times greater than in the past.
