    Hi Jimmy, Just to verify, it seems as if you may be describing two different things here. The first the removal of an entire Industry Sector, the second the removal of a single firm. We just want to be clear as to which you are looking to describe (unless there is only one firm in your region) because this can impact how you proceed. You can view the Gross and Regional Commodity Demand for Sector 221 the Explore> Social Accounts> Balance Sheet (Tab), and select View By: Commodity Balance Sheet and the Industry Demand tab. If you are interested in seeing the Institution Demand you can view that in in the Institutional Demand tab. These Regional Absorption views will be for all producing firms in the area. So the full value of the current Regional Absorption would have to obtained outside the Study Area if the entire Sector is zeroed out. These same views will show which Industries and Institutions will be impacted by the removal of local supply of 221. Please note however, that ALL Multipliers will be affected if you zero out a Sector, because in doing this you are decreasing demand on local supply of all commodities used by Sector 221. However, if you are looking at a single firm closing that does not represent the entire Industry Sector, rather than zeroing out the local Sector you would want to reduce the local production by the Output of your specific firm. This will decrease the local supply available to meet demand and thus appropriately reduce the RPC to match the new value were that firm no longer in the Study Area. The resulting change in Employment Multipliers will reflect the closure of that firm rather than the entire Sector. If instead of actual Multiplier changes you are interested in seeing the effects of the change on Employment you can examine this by means of contribution analysis. http://implan.com/index.php?option=com_content&view=article&layout=edit&id=660 If you wanted to know what the Multipliers would be if industry 221 still existed (i.e., purchased inputs) but no other industry could make purchases from it, she could also go to Customize > Trade Flows > Industry/Institution RPC, select commodity 3221 from the drop-down menu, and set the RPC to 0 for all industries and institutions that purchase 3221. Thanks!

    Ok, so let me make sure I understand correctly. Once I view the Commodity Demand tab within Industry 221, this shows me the dollar value of each commodity that would have to be purchased outside of the Study Area specifically because Industry 221 is no longer there. If this is a correct interpretation, what are the specific dollar values? Is this what the Regional Inputs column shows? Thanks!

    Hi Jimmy, I believe the area in the model you need to be in is: Explore> Social Accounts> Balance Sheet (Tab), and select View By: Commodity Balance Sheet and the Industry Demand tab. Technically you shouldn't need to modify the Model, if you are just wanting to see what the value of imports would be as this should be equivalent to the reported Gross Absorption levels, only regional demand should change- in this case to zero. The Commodity Demand tab shows the commodities or intermediate purchases that your Sector demands. The Regional Inputs display the dollar value of what can be purchased in your study region. The Gross Inputs display the dollar value of the total value of that particular commodity needed for your industry. Thanks!
