Consider an overlapping generation set up with pay-as-you-go social security system in a hypothetical economy. there are 100 old retirees and 103 young workers at the current period. old retirees earned $1,000 each when they were young. young workers now earn $1,040 each. suppose that the population growth is constant and there is a fixed payroll tax of 15%, which is used to finance the pay-as-you-go social security system. (a) what is the population growth rate, n? (b) how much is the total contribution of young workers to the social security system in the current period? (c) how much each retiree can receive from the social security system? (d) how much was the contribution of each old retiree when he or she was young? (e) what is the implicit return on the social security system?

The assumptions of the production order quantity model are met in a situation where annual demand is 3650 units, setup cost is $50, holding cost is $12 per unit per year, the daily demand rate is 10 and the daily production rate is 100. the production order quantity for this problem is approximately:

1. alwaysrain irrigation, inc. would like to determine capacity requirements for the next four years. currently, two production lines are in place for making bronze and plastic sprinklers. three types of sprinklers are available in both bronze and plastic: 90-degree nozzle sprinklers, 180-degree nozzle sprinklers, and 360-degree nozzle sprinklers. management has forecast demand for the next four years as follows: both production lines can produce all the different types of nozzles. the bronze machines needed for the bronze sprinklers require two operators and can produce up to 12,000 sprinklers. the plastic injection molding machine needed for the plastic sprinklers requires four operators and can produce up to 200,000 sprinklers. three bronze machines and only one injection molding machine are available. what are the capacity requirements for the next four years? (assume that there is no learning.)
