Data choice

Hello Ali, 1. Since the direct impact is occurring in the 6-county region, that would ideally be your study area. Then, if you are interested in seeing the impact on the rest of the state, you would run the impact as MRIO with the 6-county model linked to a model of the rest of the counties in the state. If you need to see the impacts on each of the counties separately, you can build a model of each of the 6 counties and link each of those models to models of the rest of the state. Please see this webpage for more on MRIO: https://implan.com/v4/index.php?option=com_content&view=article&id=349%3Afp5&catid=173%3Afp2&Itemid=1 2. No - that would double-count the impact. But you can incorporate both pieces of information by customizing the impact set-up. After entering the revenues into the "Industry Sales" field, you can edit the "Employment" field to reflect your known employment value. 3.

So if I want to see the impact of thes six counties on the rest of the State, do I also need to buy the State data?

So if I want to see the impact of thes six counties on the rest of the State, do I use the State level dat?

I have another question regarding MRIO. Suppose a firm is going to generate revenue in three different counties, so there would be direct effect of revenue generation in all three counties. Can you still build the multi-regional model the same way as if the revenue generation was only in one county or is there another way? Thanks.

Ideally, if you want to see the impact of these six counties on the rest of the State, we strongly recommend a State Package that includes all counties in a single State. Once you have that, you run the impact as multi-regional model with the 6-county model linked to a model of the rest of the counties in the of the state. Please see the articles in our Knowledge Base for [url=http://implan.com/V4/index.php?option=com_multicategories&view=categories&cid=236:multiregionalanalysis&Itemid=71]MRIO[/url]. If this isn't an option for you, you can use the state model, but you will need to make some edit changes to the state before running you analysis. If this is the method you choose please let us know and we can provide you with additional information. This method can be quite time consuming. In regards to your question on MRIO: If you have the data to be able to divide the portions of the direct effect between these counties you certainly could do that, so that you see the direct impact on the county in which the change is occurring and then the indirect and induced effects in that region and the linked regions. In this case you will want to build a set of models for each Direct impact you want to examine. So let's say the 3 primary counties are A, B, and C, and then you want a rest of state model (ROS). You would look at impact in A by creating the following models: A1 linked to B1, C1, ROS1 Impact stemming from B: B2 linked to A2, C2, ROS2 Impact stemming from C: C3 linked to A3, B3, ROS3 So in total you would need to have 12 models, 3 models for each region. Alternatively if you don't have the ability to differentiate out which impacts are occurring in each of the three counties, you could aggregate these three counties, use your total value in the 3 county region and then link to a ROS model. The same would apply for linking to an additional 3 county region (which you could build as one aggregate region, or keep as 3 individual counties if you wanted to see results by county). In this instance if you do ROS, just be sure none of the 6 counties you are looking at are including in that ROS model. Let us know if you need further clarification.
