Acrew of mechanics at the highway department garage repair vehicles that break down at an average of 3 vehicles every 12 minutes (approximately poisson in nature). the mechanic crew can service an average of 3 vehicles every 10 minutes with a repair time distribution that approximates an exponential distribution. the crew cost is approximately $150 per hour. the cost associated with lost productivity from the breakdown is estimated at $50 per hour. which is cheaper, the existing system with one service crew or a revised system with two service crews? note that the average waiting time for adding the second crew is 0.01.

Ajustification for job training programs is that they improve worker productivity. suppose that you are asked to evaluate whether more job training makes workers more productive. however, rather than having data on individual workers, you have access to data on manufacturing firms in ohio. in particu- lar, for each firm, you have information on hours of job training per worker (training) and number of nondefective items produced per worker hour (output). (i) carefully state the ceteris paribus thought experiment underlying this policy question. (ii) does it seem likely that a firm’s decision to train its workers will be independent of worker characteristics? what are some of those measurable and unmeasurable worker characteristics? (iii) name a factor other than worker characteristics that can affect worker productivity. (iv) if you find a positive correlation between output and training, would you have convincingly established that job training makes workers more productive? explain.
