We recently re-estimated our model of Michigan state with 2017 data and saw a drastic drop in output, but little change in jobs. This led me to be curious about how much the study area data can change from year to year. For example, sector 45 - Electric power generation - Wind has an output multiplier of 1.454 in the 2016 U.S. National data vs. 1.938 in the 2017 U.S. National data. This is a huge change for a single industry in a single year. Whereas, sector 44 - Electric power generation - Solar shows a much more modest change from 2.076 in 2016 to 2.065 in 2017. It's hard to believe that the economy for these two renewable energy industries experienced such drastically different shifts from 2016 to 2017. Can you tell me more about how the annual study area data is updated each year? Do you have any recommendations for selecting the most appropriate data year for our model?
