Suppose the city of austin, tx chooses to regulate the number of street vendors operating near the university of texas by requiring each vendor to own a permit in order to operate. the city gives free permits to all existing vendors and announces that no new permits will ever be issued. prior to regulation, the costs (including implicit costs) of operating were $85,000 and revenues were $150,000. the city ordinance allows the permits to be bought and sold without restriction. the permits have no expiration date. the interest rate is 10 percent. after regulation, existing street vendors earn an accounting profit of zero. economic profit of $130,000. economic rent of $65,000 c economic loss.

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1
