When U. S. farmers in the Southwest irrigate their land, salt in the ground soil leaks into the Colorado River. The Colorado River has become so salty that Mexican farmers further down the river cannot irrigate their own land and Mexican crops have been devastated. This situation constitutes a negative externality because: multiple choice 1 U. S. farmers consider only their external costs in their decision making. Mexican farmers consider only their private costs in their decision making. U. S. farmers consider only their private costs in their decision making. the social cost of irrigation exceeds the social benefits. If U. S. farmers were to internalize this externality, U. S. farmers would irrigate (Click to select) as the (Click to select) .

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
