Households in SAM Total Requirements Matrix
Hello, I'm interested in how economic impacts may be distributed across household income groups within an industry. I built a 2012 North Carolina model and aggregated it according to IMPLAN's 440 sector 2-digit aggregation. My SAM was set to the default of households only. I then downloaded the SAM Industry x Industry direct requirements matrix and from there built my total requirements matrix. Both my Industry Type I and SAM multipliers matched those found in IMPLAN's multiplier reports for all industries. My question concerns the other column elements for each industry, the labor income and household components. What is their proper interpretation? I believe these elements are simply telling me that an industry will purchase $X of labor income and $X dollars of commodities from each household group in response to a change in final demand. I'm unsure whether, or how, they may be providing additional insight into total household earnings and how the additional labor income is distributed across household groups in response to a final demand change for each industry. Do the household column elements for each industry provide insight into how the additional labor income would be distributed to, or across, households as well? Thanks for any and all assistance you can provide.
