Exercise 2: Refuse Collection (30 points) Consider the example of household refuse collection in Minneapolis. Assume that the marginal social cost (MSC) of collecting and disposing of it is $0.15/ lb. Suppose that in 2011 there was a fee of $0.05 /lb being charged and the quantity of refuse collected was 2.51b/p/d. Suppose that in 2012 the fee was $0.1 / lb and the quantity of refuse collected was 2.001b/p/d. Now, the government is planning to increase the fee in 2014 to $0.12/ lb. (a) (10 pts) Assuming a linear demand function, calculate the change in total surplus from an increase in the fee from $0.10/1b to $0.12/lb
