Quick Linkages Questions

Hi Ken. IMPLAN by default set all of the LPPs to 1005 in the model. The assumption is that initially all of the direct effect occurs the local study area. If you have information on what percent you think the LPP should be, you enter that value into you model and sector. However, regarding RPCs, you can view those in the model by clicking on Explore>Social Accounts>Social Accounts Reports>Commodity Summary. You can view all of the RPCs for any sector in your model. Regional purchase coefficients (RPCs) describe the proportion of each dollar of local demand for a given commodity is purchased from local producers. We hope this answers your question.

Thank you for the response. What I am really trying to get at is the ability to rank the industries in County X that have the greatest backward linkages within County X in absolute and percentages terms. Is RPC the most logical and accurate way to do this?

Hi Ken. From an earlier post, it should have said IMPLAN by default sets all of the LPPs to 100% in the model. And to your question about backward linkages, we are still looking into this. We will get back to you soon.

Hi Ken, The easiest way to look at this will be to go into the Explore>Multipliers window and sort the Output Multipliers by "Type I". The Type I Multipliers capture just the Direct and Indirect effects and thus will show which industries in your Model have the strongest backward linkages. If you also want to capture the impacts of labor spending you would sort by the Type SAM Multiplier as this Multiplier includes labor payments. The Multipliers in IMPLAN have the Regional Purchasing Coefficient values already built into their calculation so they will only show purchases local to your Model's geographic boundaries. Hopefully this helps.

Thanks!
