Suppose an economy produces two goods, food and machines. This economy always operates
on its production
possibilities frontier. Last year, it produced 1000 units of food and 47 machines.
This year it experienced a
technological advance in its machine-making industry. As a result,
this year the society wants to produce 1050 units
of food and 47 machines. Which of the
following statements is correct?
a.
Because the technological advance occurred in the machine-making industry, it will not be
possible to
increase food production without reducing machine production below 47.
b.
Because the technological advance occurred in the machine-making industry, increases in
output can only
occur in the machine industry.
c.
In order to increase food production in these circumstances without reducing machine
production, the
economy must reduce inefficiencies.
d.
The technological advance reduced the amount of resources needed to produce 47 machines,
so these
resources could be used to produce more food.
