Adding MRIO Output
Hello, I have a question regarding MRIO outputs. We are conducting a study to measure the impacts of spending in 5 different sectors in specific regions in a state. Our goal is to measure all the impacts (direct, indirect, induced) of the 5 sectors’ spending in 4 regions (county 1, county 2, county 3, and rest of state). Because we are requiring direct impacts for each region, we were planning to create 4 separate MRIO models (i.e. county 1 activities with other regions linked; county 2 activities with other regions linked etc.). If we then added up all the impacts from each MRIO output, would we be double counting any of the impacts? The spending in each of the 4 MRIO models we are creating is unique (i.e. no double counting of industry sales in the 4 separate MRIO models). Thank you.
Hello, You describe 5 different setups of MRIO analyzes. We suggest building the models for each individual county, and the Rest of State counties for less each of the 4 counties. (8 models.) You can create 5 folders for each of your MRIO iterations, and copy each iteration of the models into the specific folders. Organization is key, whereas IMPLAN only can read a model in a specific folder once. Example: a folder could be created for MRIO1, MRIO2, MRIO3, MRIO4 & MRIO5. MRIO1 Direct model: A Linked models: B, C, D & ROS. MRIO2 Direct model: B Linked models: A, C, D & ROS MRIO3 Direct model: C Linked models: A, B, D & ROS MRIO4 Direct model: D Linked models: A, B, C & ROS MRIO5 Direct model: Counties A-B-C-D Linked models: ROS. For adding them together, if the impacts are not interlinked, (i.e. an ethanol plant in region A is run in region A and Corn grown in region B for the ethanol plant in A is used as a Direct impact in region B) Please let us know if you have any further questions.
