Why Isn’t the Whole World Developed?
Introduction
This topic explores the persistent question in macroeconomics: why do some countries achieve high levels of prosperity while others remain poor? The analysis distinguishes between immediate (proximate) and deeper (fundamental) causes of economic development, and examines leading hypotheses and evidence regarding global disparities in wealth.
Proximate Versus Fundamental Causes of Prosperity
Proximate Causes of Prosperity
Proximate causes refer to the immediate factors that directly result in high levels of income and prosperity in a country.
Definition: Proximate causes are high levels of factors of production such as physical capital, human capital, and technology that result in a high level of GDP per capita.
Key Point: These causes explain how prosperity is achieved, but not why these factors are abundant in some countries and not others.
Example: A country with advanced machinery (physical capital), a highly educated workforce (human capital), and innovative production methods (technology) will likely have a high GDP per capita.
Fundamental Causes of Prosperity
Fundamental causes are the underlying reasons that explain why some countries have high levels of the proximate factors of production.
Definition: Fundamental causes are the root determinants of economic development, shaping the environment in which proximate causes can flourish.
Key Point: These causes address the deeper question of why some societies accumulate more capital, invest in education, and innovate more than others.
Categories of Fundamental Causes
Fundamental causes can be classified into three main hypotheses:
Geography Hypothesis
Culture Hypothesis
Institutions Hypothesis
Summary Table: Fundamental and Proximate Causes of Prosperity
Fundamental Causes | Proximate Causes | Outcome |
|---|---|---|
Geography Culture Institutions | Physical capital Human capital Technology | Prosperity (GDP per capita) |
Geography Hypothesis
Definition and Claims
The geography hypothesis asserts that differences in geography, climate, and ecology are ultimately responsible for the large differences in prosperity observed around the globe.
Key Point: Countries in tropical regions tend to have lower GDP per capita, while those in temperate regions are generally wealthier.
Example: Many African and South Asian countries, located in the tropics, have lower income levels compared to countries in Europe or North America.
Evidence: GDP per Capita by Latitude
Empirical data often show a correlation between latitude and income, with higher latitudes (further from the equator) associated with higher GDP per capita.
Graphical Evidence: Maps and bar charts illustrate that countries closer to the equator tend to be poorer.
Culture Hypothesis
Definition and Claims
The culture hypothesis suggests that differences in values, beliefs, and cultural practices are responsible for variations in prosperity.
Key Point: Some cultures may encourage investment, hard work, and openness to innovation, leading to greater economic success.
Example: The "Protestant work ethic" is often cited as a cultural factor contributing to economic development in Western Europe and North America.
Institutions Hypothesis
Definition and Claims
The institutions hypothesis argues that the formal and informal rules governing society—such as laws, property rights, and political systems—are the most important determinants of economic development.
Key Point: Societies with inclusive, well-enforced institutions tend to be more prosperous than those with extractive, corrupt, or unstable institutions.
Example: The divergent economic outcomes of North and South Korea, despite similar geography and culture, are attributed to differences in their economic and political institutions.
Types of Institutions
Economic Institutions: Rules that support economic transactions, such as property rights, contract enforcement, and market entry.
Political Institutions: Rules that determine who holds power and the constraints on their use of power.
Inclusive vs. Extractive Institutions

Impact of Institutions on Economic Development
Incentives: Institutions shape the incentives for individuals and businesses to invest, innovate, and accumulate capital.
Creative Destruction: Economic growth often disrupts existing power structures, which may lead rulers to resist reforms that threaten their position.
Empirical Evidence: Countries that democratize tend to experience faster economic growth and higher GDP per capita over time.
Reversal of Fortune: Historical Evidence
Urbanization and Population Density
Historical data show that regions which were prosperous in 1500 (with high urbanization and population density) are often poorer today, while previously less developed regions are now wealthy.
Key Point: This "reversal of fortune" is explained by the types of institutions established during colonization—extractive in rich tropical areas, inclusive in poor temperate areas.
Example: North America and Australasia, once sparsely populated, are now wealthy, while regions like Mexico and Peru, once centers of civilization, are relatively poorer.
Is Foreign Aid the Solution to World Poverty?
Debate and Evidence
There is ongoing debate about whether foreign aid can effectively alleviate poverty in developing countries.
Argument for Aid: Some economists, such as Jeffrey Sachs, argue that increased development aid can eliminate extreme poverty.
Critique: Many studies find that foreign aid often fails to reach its intended targets, is misused by corrupt officials, and does not address fundamental institutional weaknesses.
Key Point: If the root cause of poverty is extractive institutions, then aid alone—without institutional reform—will not lead to sustained development.
Summary of Key Concepts
Proximate causes explain the immediate sources of prosperity (capital, education, technology).
Fundamental causes (geography, culture, institutions) explain why some countries have more of these proximate factors.
Institutions play a central role in shaping incentives and long-term economic outcomes.
Historical evidence supports the institutions hypothesis over geography or culture alone.
Foreign aid is not a panacea; institutional reform is crucial for sustainable development.
