Hello I'm setting up an analysis of changes in crop acreages and production. The crops would be in various ag sectors, such as grain, vegetable and melon, and other. I have detailed crop production budgets for each crop that is changing. To use this local data to estimate the impact, could I: 1. change the production function coefficients for the ag sector using the cost data for each crop, then input the direct impact in that sector? What effect does this have if I am only considering one crop in the category and not, say, all the grain crops that are in the region? or 2. use the reductions in input purchases as my direct impacts and put them in each relevant sector (wholesale trade, machinery repairs, household income, etc.). Would I need to change anything in the grain sector if I do it this way? Do either of these options work or is one way better? Also, I need to include forward linkages, such as transportation or milling. For this, I was going to include the change in appropriate industry and make the grain sector coefficient zero. Is this correct? Thanks in advance for your help!
