MRIO Analysis Missing Results

Hi,

Our team is running an MRIO analysis for grouped counties in New York State. One of our event types is a household income change for 10001-10009. When we run the MRIO for “region #1”, we noticed positive non-zero impacts to “region #1”, but not “region 2”. In fact, IMPLAN just says this impact is missing (no results show up). We figured that this may be because household income changes are already an induced effect, so there would be no way for it to flow outside of the modeled region to other regions.

However, there are some cases where a household income change in “region #1” creates a positive non-zero impact in “region #2” when we run the MRIO.

Is this a function of how the household income changes operate in IMPLAN? Or could this be an issue with the underlying model?

Thanks

Hi there Jessica!

Without looking at your exact impacts, it sounds like you might not be seeing impacts in a certain linked region due to not meeting the threshold for commodity trading. Dollars are traded between regions for each commodity until they reach $100, at which the trading stops in the model. There is more information on this in our article: Introduction to MRIO.

If you don't think this is what is going on, please feel free to follow up.
