Tesla, the electric car maker, has
expressed an intention to carry out production in Fremont in a way that makes
intensive use of industrial robots. It
must balance this intention with the judgement and adaptability offered by
human workers and the additional productivity made possible by installing conventional
equipment for the production of automobiles.
50 robots are being leased from a Japanese provider at a cost of $100,000 per
robot per year. The marginal product of
a robot corresponds to 500 additional cars per year. Each piece of conventional equipment is being
leased from a German provider at a cost of $20,000 per year. Its marginal product is 125 additional cars
per year. The going rate of pay for the human workers is $80,000 per year. One hundred workers are employed. The marginal product of a worker amounts to
450 additional cars per year.
things equal, the marginal product of an input falls as more of it is employed.
is expected that 10 workers will quit or retire by the end of the year. Tesla plans NOT to replace them. Instead, Tesla has in mind the use of 10
additional robots next year.

equipment. Should Tesla become more
labor-intensive? More equipment-intensive? Fully explain your answers.
