Multi-regional analysis

Hi I'm using IMPLAN Pro to model the benefits of an energy project that may have employment in two different counties, in two different states. Can you confirm that the employment should be modeled in the region where it is occurring? Please also confirm this suggested approach: If all of the employment was essentially happening in Hudson County, we would model the employment in that county and then bring in NJ, NYC, and NYS to estimate indirect benefits in those regions (the adjacent counties/states). If some of the employment were in NYC, we'd have to separate out the employment between Hudson County and NYC. If the direct construction employment is occurring in two different counties then I would think there could be spillover to the adjacent counties. So we would bring in NYC/NYS to the Hudson County model and Hudson County/NJ to the NYC model. So essentially we'd be running two separate multi-county, multi-state analyses. Does this sound right? Thanks, Lorianne
