I have two questions about MRIO and trade flow analysis. I’ve read some of the papers on the subject that I’ve found online and on the website, but have some specific questions I haven’t been able to figure out yet. Specifically, it’s not clear to me how the trade flows and RPC’s are estimated for each region in an MRIO model that uses AGGREGATED regions. The more theoretical work I’ve read focuses on how the gravity model is used to estimate all county to county flows for each commodity. What happens with aggregated regions? Are the gravity model calculations rerun for each model including an aggregated region? Is there some kind of weighting of the county to county calculations used without redoing the gravity model? The second, related question, is if/how it is possible to access the RPC’s and/or inter-regional flow parameters that reflect not only the rest of world interactions with the regions or with one of the regions, but also the flows between the regions included in the MRIO. Accessible either through the menu directly someplace I’ve missed, or through the underlying Access databases? Thanks for any help.
