    Hello Janice, Thank you for your Forum post. We do not recommend MRIO in a contribution analysis. In IMPLAN, the trade flows are fixed and ignore any adjustment you’ve made to RPCs. So, suppose you have a base region A and linked region B. If in region A you set RPC = 0%, region B will still buy some of that commodity from A (assuming there is trade of that commodity between the two regions), thereby inflating A's output beyond the study area level. Plus, that industry will have to buy more inputs, so the ripple effects on other industries will also be inflated at that point. Hope this helps and please let us know if you have any additional questions. Regards, IMPLAN Staff
