Study Notes

The Lorenz Curve

The Lorenz Curve displays income dispersion, not its magnitude.
The closer the curve is to the 45 degree line, the more equitable the income distribution.
The greater the curvature of the Lorenz line, the greater the inequality in income distribution.

The Gini Coefficient

The Gini Coefficient is calculated by dividing the area A of the Lorenz curve by the area of BCD.
The Gini Coefficient is a fraction between 0 and 1.
A Gini Coefficient closer to 0 indicates a more equitable income distribution, while a coefficient closer to 1 indicates greater inequality.

Principles of Inequality Measurement

Population Independence Principle: Inequality should not be influenced by the number of income recipients.
Transfer Principle: If income is transferred from a richer to a poorer person, resulting in a new distribution, the new distribution should be considered more equitable.
Monotonicity: If income is added to someone below the poverty line, with all other incomes constant, poverty should decrease.
Distributional Sensitivity: Transferring income from a poor to a rich person should result in a strictly poorer economy.

Kuznets Inverted-U Hypothesis

Economic growth may initially lead to greater inequality.
This is because growth is often driven by the productive sector, which benefits higher-income earners.

Poverty Measurement

Governments may aim for single-digit poverty incidence, but this is immaterial if other ideal properties of poverty measurement are not met.

Focus Principle

A good poverty measure should be based on the well-being of the poor, not the non-poor.

Millennium Development Goals (MDGs)

The MDGs were a set of eight goals adopted by the United Nations in 2000 to improve the lives of people around the world.
They covered areas like poverty eradication, education, gender equality, child mortality, maternal health, HIV/AIDS, environmental sustainability, and global partnerships.
The target completion date was 2015.

Sustainable Development Goals (SDGs)

The SDGs are a set of 17 goals adopted by the United Nations in 2015 to continue progress made under the MDGs and to address new global challenges.
They focus on achieving a more sustainable and equitable future for all.
The target completion date is 2030.

Population Growth

Less developed countries tend to have higher population growth rates.
This is partly due to the difficulty of ensuring adequate resources for larger families in less developed contexts.
Stabilizing population growth rates are a sign of development.

Population Momentum

Despite lower fertility rates, populations can still grow due to the large number of people in younger age groups.
This is called population momentum.
It takes time for changes in fertility rates to be reflected in overall population growth.

Empirical Evidence on Fertility Rates

Studies show that higher female education and employment opportunities are correlated with lower fertility rates.
Improved child survival rates also decrease the need for larger families.

Demand Function for Children

Having children comes at a cost.
Parents need resources to provide for their children's needs.
People tend to prioritize having quality children.

Factors Influencing Fertility Rates

Increased female non-agricultural employment at higher wages
Higher education, role, and status for women
Expanded schooling opportunities with lower real costs
Increases in family income levels
Reduced infant mortality and better healthcare
Development of old-age and social security plans

Coordination Failure

Coordination failures occur when individuals act in their own best interest but collectively lead to a worse outcome.
An example is climate change, where individuals may feel their small actions have no impact, leading to no change.

Basic Indicators of Development

Gross National Income (GNI)
Gross Domestic Product (GDP)
Purchasing Power Parity (PPP)

Holistic Measures of Living Levels and Capabilities

Income
Health (Life Expectancy)
Education
Traditional Human Development Index (HDI)
New Human Development Index (NHDI)

Three General Types of Colonial Institutions

Settler Colonial Institutions: Established in areas where colonists intended to settle permanently (e.g., North America, Australia).
Extractive Colonial Institutions: Focused on extracting resources for the benefit of the colonial power (e.g., many African countries).

Nature and Role of Economic Institutions

Economic institutions are the rules of the game that shape economic behavior.
They can influence factors like investment, innovation, and resource allocation.
They can be formal (laws, regulations) or informal (social norms, customs).

Key Elements of Strong Institutions

Security of property rights: Encourages investment and innovation
Enforcement of contracts: Promotes trust and predictability
Restriction of coercive, fraudulent, and anti-competitive behavior: Ensures fair market competition
Constraining the power of elites: Reduces corruption and inequality
Conflict Management: Promotes stability and development
Improved coordination: Facilitates cooperation and collective action
Social insurance: Provides safety nets for those facing economic hardship
Predictable macroeconomic stability: Ensures that economic policies are consistent and predictable

Relationship Between Institutions and Development

Strong institutions can both cause and improve development.
They can help create the conditions necessary for economic growth and improve well-being.

The Role of Government

Governments have a crucial role in establishing and maintaining strong institutions.
They should promote policies that support economic growth, reduce inequality, and promote social welfare.

The Importance of Policy

Institutional reforms are key to promoting convergence across countries.
Governments should implement policies that foster innovation, investment, and human capital development.

Latecomer Advantage

Developing countries can sometimes benefit from a "latecomer advantage" by learning from the experiences of advanced economies.
They can adopt new technologies and best practices more quickly, reducing their need to experiment.

Convergence Debate

The debate continues regarding whether living standards are converging across countries.
Some argue that globalization and technological advancements are bringing countries closer together.
Others point to persistent inequalities and argue that convergence is not happening as rapidly as predicted.
