Please help me understand how to work out each part in detail. I want to understand the steps for each part. Thank you!

Question 4. Incentive Based Policy for Market Failure - Transferable discharge permits Marginal Abatement Costs The marginal abatement costs for reducing Emissions emissions for two sources appears in the table (tons) Source A Source B below. Each is currently emitting 12 tons so that 12 0 total emissions are 24 tons. Please show your 11 2 work for any calculations. (*#*Note on interpreting 10 12 table: for source A, abating the first unit --to go from 12 6 18 to 11 tons emitted -- costs 2.) 8 24 10 30 12 36 a. For A and B, calculate the TAC (total 42 abatement costs) for a uniform standard, ie. 48 equal percentage (equiproportional) cutback, to 16 total tons emitted. Emissions are 60 abated so that Emissions + Emissionss = 16. 66 72 b. Suppose the regulator uses a tradable permit policy. Each source is given & permits for free and permit trade is available. After trade (if any), how many tons are emitted from A and B? Emissions: Emissionss' c. Suppose the price paid for each permit exchanged between A & B is equal to the MAC of the final unit abated. What is the total cost of compliance (total abatement cost + total permit cost) for A and for B? TCCA = TCCB d. How does the total cost of compliance overall (TCC = TCC, + TCC:) under this cap and trade approach compare to the total cost of compliance under a uniform standard for achieving the same aggregate pollution level?
