Equatorial Guinea experienced a massive surge in GDP per capita after offshore oil was discovered in the 1990s, yet most citizens saw little improvement in living standards, health, or education. Which concept best explains this divergence?
AThe Kuznets curve — inequality always rises before it falls during industrialization
BGrowth without development — GDP increased but welfare gains were captured by a small elite, leaving broad human capability unchanged
CThe resource curse — oil-producing nations always experience negative growth as a result of Dutch disease
DMeasurement error — official GDP statistics overstated the actual level of output
Equatorial Guinea is a classic illustration of why growth and development must be distinguished. GDP growth requires only that aggregate output increases — it says nothing about how that output is distributed or whether it translates into health, education, or freedom. If gains are concentrated at the top, most of the population may experience no improvement in the capabilities that Sen's framework treats as the substance of development. This case motivates the entire field: if GDP alone could measure welfare, development economics as a separate discipline would be unnecessary.
Question 2 Multiple Choice
Country A has GDP per capita of $50,000 but ranks poorly on political freedom, gender equality, and access to healthcare for rural populations. Country B has GDP per capita of $8,000 but ranks near the top on health outcomes and literacy. Which is more 'developed' in the sense used by development economists?
ACountry A — GDP per capita is the definitive measure of development and Country A's is far higher
BThe question is unanswerable — development is purely subjective and cannot be compared across countries
CIt depends on which dimensions you weight — development is multidimensional, and neither country dominates on all measures
DCountry B — health and literacy matter more than income in development economics
Development economics explicitly rejects the idea that GDP per capita settles the question. Because development is multidimensional — health, education, freedom, opportunity, as well as income — countries that lead on one dimension can lag on others. Sen's capabilities approach would say Country A offers fewer substantive freedoms in some domains than its income suggests, while Country B achieves high capabilities with modest income. Composite indices like the HDI exist precisely to make these multidimensional comparisons tractable, not to replace judgment with a single number.
Question 3 True / False
According to Amartya Sen's capabilities approach, income is instrumental to economic development but is not the same thing as development itself.
TTrue
FFalse
Answer: True
This is the core of Sen's argument and the conceptual foundation of modern development economics. Income matters because it buys food, medicine, and schooling — the inputs to capabilities like living a long healthy life, being educated, and participating in society. But income is a means, not an end. A person with high income but no access to healthcare or political voice lacks important capabilities that development is supposed to expand. Conversely, some high-capability outcomes (clean air, civic participation, social trust) are not simply purchased with income. This distinction motivates measuring development directly rather than using income as a proxy.
Question 4 True / False
A country with high GDP per capita is, by definition, economically developed — other indicators like health and education are secondary concerns that improve automatically as income rises.
TTrue
FFalse
Answer: False
History refutes this. Saudi Arabia, for instance, has very high GDP per capita but ranks lower on gender equality and political freedom. The Gulf states' resource wealth produced high income without the broad human development gains that the 'income determines everything' view predicts. The claim that other dimensions improve 'automatically' as income rises — the trickle-down hypothesis — is an empirical claim that is frequently falsified. The entire rationale for development economics as a field, and for indices like the HDI, is that income and welfare are related but distinct, requiring separate measurement and separate policy attention.
Question 5 Short Answer
Why did development economists create composite indices like the Human Development Index instead of simply using GDP per capita to track progress across countries?
Think about your answer, then reveal below.
Model answer: Because GDP per capita measures only the quantity of economic output, while development is fundamentally about improving the quality of human lives — health, education, freedom, and opportunity. Countries can grow (increase GDP) without developing (improving welfare), as when gains are captured by elites, or when growth comes from an enclave sector that doesn't employ most of the population. GDP also misses critical dimensions like political freedom and gender equality. Composite indices capture multiple dimensions simultaneously, revealing cases where income and welfare diverge and prompting more targeted policy responses.
The HDI's creation by Mahbub ul Haq and Amartya Sen in 1990 was a direct challenge to the practice of ranking countries by GDP alone. They argued that 'people are the real wealth of nations' and that a measure of development should directly capture whether people can live long, healthy, educated lives — not just whether their country produces a lot. The index also changed policy conversations: countries that ranked lower on the HDI than their income predicted were identified as underperforming on human welfare relative to their resources, prompting scrutiny of how national income was being used.
