A hotdog factory produces 60,000 hotdogs each week. The equipment used costs $10,000 and will remain productive for 4 years. The labor cost per year is $13,500. What is the productivity measure of units of output per dollar of input averaged over the four-year period? Hint: Productivity = total units produced divided by the total labor cost plus total equipment cost We have the option of $13,000 equipment, with an operating life of 5 years. It would reduce labor costs to $11,000 per year. Should we consider purchasing this equipment (using productivity arguments alone)?
