Recall the exhibit in the text that compares the Lorenz curves of the United States, Brazil,
Sweden and France. Which lies closest to the diagonal?
a.United States
b.Brazil
c.Sweden
d.France
e.Brazil and Sweden are almost identical and closest to the diagonal.
92. Lorenz curves supposedly reflect the disparities of standards of living among people
living in a society but they cannot take into account factors that can greatly affect the
disparities. Among them are all the following except
a.the size of population
b.the availability of public housing and housing subsidies
c.national health care systems
d.national education systems
e.social security programs
93. The transformation of a Lorenz curve into a numerical value is
a.the value of the diagonal minus the value of the two sides of the right angle triangle
b.the sum of the percentages of income for all groups
c.the Lorenz coefficient
d.the Gini coefficient
e.the value of the midpoint on the Lorenz curve
94. If the Gini coefficient is zero, then we know
a.the value of the Lorenz curve must be one
b.the income distribution is perfectly equal
c.the richest quintile receives all the income
d.the income in the economy has not changed
e.the Lorenz curve lies above the diagonal
95. For real-world economies, the Gini coefficient lies between
a.1 and 10
b.0 and 100
c.0 and 1
d.–1 and +1
e.0 and infinity
96. If we know that the area between the Lorenz curve and the diagonal is 2,500, and the area
of the square (the triangles above and below the diagonal) is 10,000, then the Gini
coefficient is
a.0
b.0.25
c.0.50
d.0.75
e.1.0
97. Suppose a Russian economist told you that since the fall of communism, the Russian
income distribution has shifted to perfect inequality, you would know then (no need to
calculate), that the Russian Gini coefficient is
a.1
b.0
c.10
d.-1
e.infinite
98. Two South Pacific islands, Aba and Ema, have very different Gini coefficients. Aba’s is
0.90 and Ema’s is 0.40. That’s enough information to tell you that
a.both islands have a relatively equal income distribution because their Gini
coefficients are both less than 1
b.Aba’s income is growing faster than Ema’s
c.Ema’s distribution of income is less equal than Aba’s
d.Ema’s distribution of income is more equal than Aba’s
e.Aba’s population is growing faster than Ema’s
99. Over the last few decades, the U.S. Gini coefficient has
a.become negative
b.increased moderately
c.decreased moderately
d.decreased dramatically
e.fallen from 1.50 to less than 0.25
100. In the last 15 years, the U.S. Lorenz curve has
a.become a straight line
b.become a decreasing curve
c.moved closer to the diagonal
d.moved further from the diagonal
e.not shifted but there has been an upward movement along the curve
