4. {8 points} Create a marginal abatement cost function for carbon emissions using the DICE model. http:www.econ.yale.eduf'\"nordhausfhomepage/homepagefdocuments/DICE Manual 100413r1.pdf a. C. (2 points] In the GAME code for the DICE modei, nd the equation for MCABATHt} on page 100 of the user manual. This is the marginal cost of abatement in dollars per ton of C02. In this equation, gbacktimeit) is the price of a carbonneutral backstop technology (such as wind or solar power). MIUIt} is emission control rate, or the fraction of the carbon emissions which are "controlled.\" MIU{t] is a value between 0 {no emissions controlled], and 1 {all emissions controlled]. The variable expoostZ is a parameter for the exponent. Write Dr. Norhaus' equation for marginal cost per ton, MCIt, as a function of the backstop price, p, the fraction of emissions controlled, p, and the exponent, x. {In other words, use the variable p for \"pbacktime,\" p for MIU, and x for expcostZ.) (2 points] In the DICE model, the price of the backstop technology declines over time. However, for simplicity, assume that the backstop price, p, remains constant at the initial price, which variable "pback" in this model. Find Dr. Nordhaus' assumptions for the values of Qback and x on page 97 of the user manual. Report those vaiues here. (2 points] Recall that the equation your reported in part 4.a is the marginal cost of controlling C02. You can convert this to an equation for carbon by simply multiplying it times 3.67. Substitute the values for p and xthat you reported in part 4.b into the equation you found in part 4.3 and multiplytimes 3.67 to obtain a value for the marginal cost per ton of controlling carbon, Mcft, as a function of the fraction of emissions controlled, p. (2 points] Assume that 50% of emissions are controlled {p205}. What is the marginal cost of controlling the last ton of emissions? 2. l[llbtain the Introduction and User's Manual for DICE 2013B from the class site. htt : www.econ. ale.edu "nordhaus ome e home a e documents DICE Manual 100413r1. df a. Read sections "LA and \"LE. on pages 615 of this User's Manual for DICE 2013R. This will give 'you some background into the economic component of this wellknown integrated assessment model. (Note: The Egg; letters in this user manual are not the same parameters as the gLeneh letters given in part 1.} You do not need to report anything for this part. b. Familiarize yourself with the GAMS code for the \"Vanilla\" version of this model, found on pages 9&102 of this user manual. This is a simplified version of the model. It uses slightiv more simplied versions of the equations given is sections "LA and "LB that your read for part 2.a. You do not need to report anything for this part
