I will follow up with the team on the question that we discussed yesterday, but let me repeat it here to make sure I understand. The interagenc y group generally accepts that these regulations should lead to a reduction in transportation prices inherent in our VMT rebound estimate. The stumbling block seems to be how well does the general equilibrium economy wide model relate a pr ice change in the transportation sector to an overall GDP change. I will ask the team what kind of information we have that would answer questions about the validity of the model to make that kind of estimate. I am assuming that we will talk about this a t 11:00. Thanks, By ron

As you will note, the SAB was supportive of EPA's gu idance to use general equilibrium modeling to capture the impact of regulations that will have significant impacts beyond those directly subject to regulation. (see highlighted sections in the attachment)

In addition, we have also attached a copy of the 2010 peer review report of the IGEM and ADAGE models, which also recommends incorporating the use of CGE models in EPA's analysis of climate related policies . According to this report, "On balance, these are two excellent models that provide useful i nformation to EPA as it goes about its work of evaluating climate policies...These models are essential tools for the analysis of environmental policy in general and climate policy in particular." (see highlighted sections in the attachment)Also, we think it is important to point out that in response to some of the issues raised in

context of the Light- Duty rulemaking, we have modified the preamble and RIA language to be as specific as possible on what the analysis represents, and what it does not re present. For example, we have included caveat language that points out that the GDP and consumption information does not represent a welfare analysis:

"

### Note that GDP changes should not be confused with a measure of welfare since it focuses only on change s in what is produced by the economy, not what is consumed. " 

### (Preamble Chapter 8.L(1), footnote in 2nd paragraph) In addition, we are explicit that the results of the economy- wide analysis are dependent upon our assumptions regarding fuel savings. 

### "It is important to note, however, that these potential impacts do not represent additional benefits or costs from the regulation. Instead, they represent the effects on the U.S. economy as its direct benefits and costs are transmitted through changes in prices and quantities sold in the affected markets, including those for vehicles and their components, fuel, and the various resources used to supply them. The predicted impacts of the regulation on economic activity depend on what we assume with regard to fuel savings. In particular, it depends on the extent to which market failures affecting demand for vehicle fuel economy are present, and when they are not, the extent to which they are offset b y costs not captured in EPA and NHTSA's anal ys is. Such costs include changes in economic welfare due to the purchase of more fuel economy than businesses would otherwise elect to purchase absent regulation." (Preamble Chapter 8.L, 3rd paragraph) However, if there is specific language that you are still uncomforta ble with, we welcome suggested edits and would like to work address those issues.

It is important to note that the results of th is mo deling exercise are dependent on the assumptions associated with how producers will make fuel econom y im provements and how consumers will respond to increases in higher vehicle costs and improved vehicle fuel econom y as a result of the program. //436 See Mem orandum to Docket, ‘‘ Econom y-Wi de Im pacts of Proposed Greenhouse Gas Tailpipe Standards, ’’ March 4, 2010.

Chet France/AA/USEPA/US@EPA, W illiam Charmle y/AA/USEPA/US@EPA Date: 09/28/2010 06:04 PM Subject: HD NPM - Economy wide modelling Hi Chandana,Following is a discussion of how price changes are propagated through the economy wide mo delling. Please let me know if we can provide anything else. Thanks, By ron The impact of fuel price changes on the rest of the econom y is determined endogenously within IGEM, and is governed by the structure of production and consumption in the model. All of the parameters in the model are econometrically estimat ed using a data set that includes a sequence of input- output tables spanning 50 years. The use of fully flexible translog functional forms with econmetrically estimated parameters allows historical behavior to govern response to price shocks in the model. (see Christensen, L; Jorgenson, D; and L. Lau. (1973) "Transcendental Logarithmic Production Frontiers" The Review of Economics and Statistics. Vol. 55, No. 1 (Feb., 1973)) The methodology used by the IGEM model for estimating price responses through out the econom y has been successfully peer reviewed recently (See: Peer Review of Computable General Equilibrium Models for Climate Change Analysis, April 2010, sent last week). Several relevant excerpts are included below: 

### What are the overall major str engths and weaknesses of the model for EPA’s intended purpose? The main strength of both models [IGEM and ADAGE] is their internal consistency and ability to capture complex interactions among different sectors of the economy in response to climate policy. Both also have considerable detail about energy production and industry sectors that are particularly sensitive to higher energy prices from climate policy.

... 

### IGEM’s strengths are its econometric calibration to historical data, ability to capture detail ed sectoral impacts, and its sophisticated representation of endogenous incremental technological change. Are the underly ing data used to benchmark the model (e.g. input - output table or Social Accounting Matrix) appropriate? As Donald Rumsfeld might have said, you develop a model based on the data you have, not what you might like to have. However, even given this caveat,economic data used in these models appears to be adequate and certainly the best that is readily available. ADAGE uses IMPLAN social acco unting data, widely recognized as some of the best subregional economic data. ADAGE also used GTAP data for international information, similarly the best that is available. The IGEM model is also closely tied to data. Given that the IGEM model has been developed over several decades, and has used the best national data that is available, IGEM cannot be faulted in terms of economic data used to estimate the model.

edits, I suggest we setup a conference call today to work through them and close out this discussion.

W e have updated the fuel savings language to parallel the approach from LD (fuel savings as benefits in 2014 - 18 model year discussions, shown both ways in calendar year discussions). Econom y wide modelling is done exactly as LD (the section is deleted in its entirety and the sentences from LD brought to the same location in this package). Our updated AB&T language is copied below in a separate document. I believe the only open item from yesterday's call is the table from the LD 2012 - 2016 rule executive summary

that you wanted carried over in concept for this proposal. If you can send me the table number, we will be glad to follow up. Thanks, By ron
