Hi. I'm trying to update some work I did a few years back using the IMPLAN desktop software now that I'm using the IMPLAN web based software. Both analyses use the USA file (i.e. they're national). The original work used 2010 tables, for the new one I'm using 2014 tables. I wanted to check my old results before updating things, so I took the exact inputs I ran back then in the 440 sectoring scheme (downloading the old inputs into excel), converted it to the 536 sectoring scheme using your crosswalk, and then uploaded into the new system. In both cases, both all the event years and the output display year are 2013. In both cases, it's an industry change. I checked to make sure the overall sum of the inputs was the same, and it is. I'm finding though that the impacts of the new model are a full 13% lower than the impacts of the old model (judged pretty much any way you'd like, but I'm referring specifically to value added for the 13% number). I can understand that the results wouldn't be identical, but this is a huge difference. Do you know what could be causing this? Thanks.
