Which statement about the relationship between the conceptions of development is most accurate?
D. Capability and basic-needs views treat income growth as a means, valued for what it does for people's lives
Modern conceptions layer on the growth view: income remains important as a means, but the end is poverty reduction, capability expansion and sustainability. Sen does not reject growth, Seers explicitly rejected income per head as the sole test, and sustainability constrains the pattern of growth rather than requiring zero growth.

Growth is called 'pro-poor' in the relative sense when
A. the incomes of the poor grow faster than average income
The relative definition requires the growth incidence curve to be higher at the bottom than the mean, so inequality falls. The absolute definition only requires the poor's incomes to rise. A constant Gini means distribution-neutral growth, which is pro-poor only in the absolute sense.

Sen's transfer axiom requires that a poverty measure rises when income is transferred from a poor person to a richer person. Which measure satisfies this axiom?
A. The squared poverty gap
A transfer between two poor people leaves the headcount and the total poverty gap unchanged (or can even lower the headcount), so neither responds. The squared gap weights larger shortfalls more, so a transfer away from a poorer person raises it. The income gap ratio has the same insensitivity as the poverty gap.

Four people have incomes 0, 0, 0 and 100. Using the formula Gini = (sum over all ordered pairs of |x_i - x_j|) / (2 n^2 mean), the Gini is
A. 0.75
Pairs with a difference of 100: the rich person paired with each of three others, counted in both orders, 6 x 100 = 600. Mean = 25, n = 4: Gini = 600/(2 x 16 x 25) = 0.75. With n individuals the maximum discrete Gini is (n - 1)/n, not 1, a common trap. 0.38 counts each pair once (300/800 = 0.375), and 0.25 is 2B, twice the area under the Lorenz curve (2 x 0.125), instead of 1 - 2B.

The growth diagnostics approach of Hausmann, Rodrik and Velasco (2005) recommends that reformers
C. identify the most binding constraint on growth in each country and address it first
Growth diagnostics uses a decision tree (low return to investment versus high cost of finance, appropriability versus social returns) to find the binding constraint, rejecting uniform reform lists.

In Acemoglu and Robinson's framework, 'extractive' economic institutions are those that
A. concentrate power and income in a narrow elite and weaken incentives for broad investment
Extractive institutions transfer resources to an elite and deny secure property and open entry to most people; inclusive institutions do the opposite. The term does not mean mining, and taxation by itself is compatible with inclusive institutions.
