A crate manufacturer has been able to produce 240 crates per 100 logs with his current
equipment. He currently purchases 100 logs per day, and each log requires 3 labor-hours to
process. He believes that he can hire a professional buyer who can buy a better-quality log at the
same cost. If this is the case, he can increase his production to 260 crates per 100 logs and his
labor-hours will increase by 8 hours per day.
a.
b.
What will be the impact on productivity (measured in crates per labor-hour) if the buyer
is hired?
Suppose that he has decided to look at his productivity from a multifactor perspective and
he has determined the additional input requirements as follow:
Material:
Capital:
Energy:
Current System
100 logs per day = $1,000
$350

is VND30,660 per hour. Suppose further that U.S. workers are 11 times more productive than
Vietnamese workers.
a.
b.
What is the “relative” wage rate (in dollars) of operating in Vietnam, after taking
productivity differences into account?
If the U.S. wage rate is USD15.94 per hour, are labor costs (relatively) cheaper in the U.S. or
Vietnam?
