permits, what is the total cost of the pollution reduction?

Initially the beef and mutton markets are in equilibrium, then preferences shift away

strategy is to

Suppose that you rent a house next to a dog kennel. The kennel holds up to 200 dogs at
a time, and these dogs bark all day long. You now have to spend $150 more per month
on earplugs and headache medicine because of the noise. You could move to another
house far enough away from the factory, but the rent for that house is $125 more than
you now pay. The efficient solution to this problem is that
A) the kennel owner should compensate you $150 so that you can pay for the additional
expenses you incur.
B) you should move to the new house because the additional rent on that new house is
less than the additional expenses you incur from living next to the kennel.
C) the kennel owner should reimburse you $25, the difference between your expenses
and the higher rent on the new house.
D) the kennel should be able to continue to operate as it is because only one person is
being harmed by the noise.

Scenario 1. Suppose your instructor informs the class that the highest grade on each of
his multiple-choice exams will automatically receive a 100. All other grades below this
will be based on this high grade. For example if the highest grade is an 80 this would
receive an automatic 100. If someone scores a 40 then the grade earned would be a 50
[(40 80) * 100%)]. To the instructors surprise all the students earned a 100 on the first
exam even though their grades were all an identical 25%. How could this have
happened?
Using the scenario above why might the results be different for small classes compared
