Why some countries rich and others poor?
Why some countries grow while others grow slowly or not at all?
How did some East Asian countries advance from poverty to relative prosperity in just 30 years?
Why many African countries remain in deep poverty?
Sustained development and poverty reduction cannot occur in the absence of economic growth

Divergent Patterns of Economic Growth Divergent Patterns of Economic Growth since 1960 since 1960
After 1960s LDCs begin to diverge
For example per capital income in Thailand was $1100 and that of Zambia was $1200
Thailand now has per capita income of $9500*, but Zambia is about $1600*?
What happened? Growth difference: Thailand grew over 4.5% and Zambia growth was -0.6% (negative)

Why is Botswana Successful (Read Box Why is Botswana Successful (Read Box 3.1)3.1)
Between 1970-90, Botswana was the fastest growing country in the world at about 8% per year.
But at independence in 1965, it was poor it had 100 high school graduates and 22 college graduates.
What is the main source of success: Good policies and strong institution and democratic government
Protection of property rights and minimal corruption including civil service base on merit not on patronage
These has led to highest per capital income and best HDI
Recent challenge: High HIV/AIDS infection rate has reversed this.

Growth Growth Factor Accumulation: increase in the size of capital stock and labor force. More machines, factories, buildings, roads, electricity, computers and tools along with better trained workers
Productivity Growth: Amount of output per unit of machine or worker: increases in 2 ways by greater efficiency-specialization, and technological change.
This can be explained using production function
Q= f (Labor, Capital, etc…)

Key Elements of Economic Growth
New investment increases the capital stock
Investment (I) is financed through savings (S) I=f(S)
Savings comes from income of GDP S= f(GDP)
These decisions are made by consumers, firms corporations, & governments
Sustaining Growth requires both generating new investment and making sure it is productive & employment creating.

Macroeconomic stabilityMacroeconomic stabilityMacroeconomic stabilityMacroeconomic stability
Macroeconomic implies avoiding inflation and recession. An extreme case of high inflation: Zaire/Congo=2800%, more recently Zimbabwe 4000%! Primarily by printing too much money to pay for deficeit
Political instability in the form of civil war, military coups, cross-border wars are rampant in Africa
2/3 of African states suffer from conflict
See figures 3.2, 3.3

Investment on Human capital is a key as it translates to longer life, healthier and productive population.
Health and Education are both input or means and outcome (goal) of development.
Increase in the level and quality of Education and health is crucial

1. market institutions that protect property rights
2. Market regulating institutions that deal with market failure
3. Market stabilizing institutions to control inflation
4. Market legitimizing institutions such as social protection and insurance
5.Political institutions determine how a country is governed: level of democracy, transparency, free press, participatory politics, and competitive parties. See Figure 3.5 Governance and Growth

Growth depends on millions of private citizens making decision to save, invest, work, educate, etc
Agricultural policies are central in Africa since 70-80% of the population lives from agriculture
Hernando de Soto: The Mystery of Capital
Heavy business regulation and weak property rights under mine or kill businesses
The degree of openness to international trade and influence matters see Figure 3.6

Does Geography Matter?Does Geography Matter?Does Geography Matter?Does Geography Matter?
Most economically developed states are in Temperate climate Zone. Most developing countries are in the tropics. “The effect of climate”: Andrew Kamrack argument.
Does being land locked matter? (no coast line). Yes and no
Botswana is land locked but it is most successful African Economy
Switzerland and Austria are land locked yet they are wealthy countries.

Richer countries with capital abundant grow slowly
Since poor countries have more potential to grow faster they can catch up with rich countries

The Convergence Debate: Is The Convergence Debate: Is there convergence?there convergence?
There may be convergence among open economies that share the same features
For example East Asian Economies since 1965 (Sachs and Warner, 1195)
Other studies show there no evidence of absolute convergence but there may be conditional convergence. (See figure 3.2)

Economic Growth & Structural Economic Growth & Structural ChangeChange
Economic Growth & Structural Economic Growth & Structural ChangeChange
Growth involves more than increases in per capita income and rise in factor productivity
Structural change must take place in 4 ways
1.Proportion of output from agriculture declines, share of manufacturing & services rise
2.Proportion of Labor engaged in agriculture declines and labor force in industry rises
3.Population becomes more urbanized & cities and towns grow over time
4. Greater share of output is sold in markets.
5. Ignoring agriculture in early stage is a mistake

Reasons for the Decline of Reasons for the Decline of Share of Agriculture Share of Agriculture
Reasons for the Decline of Reasons for the Decline of Share of Agriculture Share of Agriculture
1. Engel’s Law: as income the share of expenditure on food declines and expenditure on non-food such as recreation, clothing, housing, etc rises.
2. Productivity gains in agriculture frees labor for non-agricultural goods or manufacturing and service production. Technology (improved seeds, fertilizer, machinery,etc) allows less labor to produce food
Example in 18th & 19th century the majority of Americans were in agriculture, now only 3% of US population is engaged in agriculture and 97% in industry and services.

Chapter 3: Economic Growth Chapter 3: Economic Growth SummarySummary
• 1. A nontechnical overview of economic growth. The main questions posed are Why are some countries rich and others poor, and why do some countries grow quickly and others grow slowly? The chapter broadly observes the performance of groups of countries and divides their growth into the following categories: negative, slow, moderate, and rapid.
• 2. Basic mechanisms of economic growth and break them down into factor accumulation and productivity growth. Basic features of the production function and the concept of diminishing returns. The key ideas and implications of the Solow model are presented in a nontechnical manner. Followed by the idea of diminishing returns to convergence and explores the convergence debate.
• 3. The analysis of the sources of growth decomposition is shown, and the idea of total factor productivity is introduced. The authors then trace the results of the empirical work on sources of growth from Solow to Collins and Bosworth (who find that developing countries rely more on capital accumulation).
• 4.The five main characteristics of rapidly developing countries: macroeconomic and political stability, investment in health and education, effective governance and institutions, favorable business environment, and favorable geography. Using new data, the text explains the idea of structural change.
• 5Boxed Examples: There are two boxed examples. 1,The economic success of Botswana. 2.Summary of the recent research on institutions and economic growth
