Between 1970 and 2010, the poverty rate in East Asia declined dramatically from about
60 percent to less than 1 percent, while the poverty rate in Sub-Saharan Africa
decreased from 40 percent to only 24 percent. The main reason for this is that
A) the population growth rate decreased in East Asia and increased in Sub-Saharan
Africa.
B) Governments in East Asia increased transfer payments to poor families over this
period of time. The governments of Sub-Saharan Africa had practically no transfer
payment programs from 1970 to 2010.
C) The countries of East Asia have progressive income tax systems. The countries of
Sub-Saharan Africa all have regressive income tax systems.
D) East Asia experienced higher economic growth than Sub-Saharan Africa.
Which of the following explains why talented major league baseball players command
much higher salaries than neurosurgeons?
A) because the total value of baseball games is much higher than the total value of
neurosurgery
B) because it takes far more skill and training to be a major league baseball player than
to be a neurosurgeon
C) because the supply of talented major league baseball players is relatively low
compared to the supply of neurosurgeons. Therefore, major league baseball players
exert far more market power than neurosurgeons.
D) because the supply of talented major league baseball players is low relative to its
demand compared to the supply of neurosurgeons. Therefore, adding another player
yields far greater marginal benefit than adding another neurosurgeon.
