As stated in the RFQ and the RFP, the OCS EIM have 2 conceptual steps, the first estimating the level of spending (by sector and location) and the second converting the spending into estimates of employment, personal income, etc.  The sample model for the Gulf of Mexico is a full 2-step model.  There are three sample models for the Alaska OCS.  The first two are 1st-step models.  The third, consisting of four linked files, would normally be a full version of Sub-Arctic IMPAK.  However, the links would have to be re-established for the model to work.  (See document no. 4 below.)  The first three Alaska files are “final” versions of first-step models recently received from the contractor, and they are under MMS review.

Some of the models, especially those with IMPLAN multipliers, contain proprietary or confidential data.  Therefore, they are for examination only and are not to be used for work unrelated to this contract without specific permission.

Documentation and Labor Needs survey files are in Adobe’s Portable Document Format (pdf).  Excel files are in Excel 2002 (Office XP) xls format.  Access files are in Access 2002 (Office XP) format.

If the models do not open correctly, save them to your own hard drive or network, then open them. You must “Enable Macros” for the Alaska Excel models to work properly. Also note that the 3 documents linked to the Documentation worksheets in the Arctic files are provided on this site.
