Problem 2 A company that makes candles, has 4 workers, one machine and the company produces 80 candles per hour on average. Labor cost is $10 per worker per hour, and machine cost is $15 per hour.
• Calculate labor productivity. Use candles per worker per hour as the measure of labor productivity.
• Calculate the multifactor productivity. Use candles per dollar cost (labor plus machine) as the measure.
When calculating productivity, check the unit that you are asked to use.
In the first part, the measure is candle per worker per hour. As stated in the problem for
output of 80 candles, the input of 4 × 1 worker hours are used. Therefore labor productivity
is 80 = 20 candle per worker per hour. 4
For the second part, the unit is candle per dollar cost. As stated in the problem, for the
output of 80 candles, the input (in terms of dollars) of 4 × 10 + 15 × 1 = $55. Therefore, the
multifactor productivity is 80 candles per dollar. 55
