In the multi-regional model, every row and column is a country–sector pair. D and N are the two results most users work with.
| Symbol | Name | In words | Units |
|---|---|---|---|
A (Adom, Aimp) | Direct requirements | Inputs bought per dollar of a sector’s output, split into domestic and imported | $ / $ |
L | Total requirements (Leontief inverse) | All the output needed across the whole supply chain per dollar of final demand | $ / $ |
V | Supply (Make) table | Production of each commodity by each domestic industry | $ |
U (Udom, Uimp) | Use table | Commodities bought by each industry as inputs, split into domestic and imported | $ |
x | Industry output | Total output of each industry: the row sums of V | $ |
q | Commodity output | Total domestic output of each commodity: the column sums of V | $ |
y (ydom, yimp) | Final demand | Purchases by households, government, investment, and exports, split into domestic and imported | $ |
ynab | Final demand for the national accounting balance | Final demand for domestic production: ydom plus exports | $ |
E | Emissions | Emissions of each gas by each sector, weighted by AR6 GWPs | kg CO₂e |
B | Direct emission intensities | Emissions of each gas per dollar of a sector’s own output, in CO₂e | kg CO₂e / $ |
M | Total emission intensities by gas | B × L: emissions of each gas across the supply chain per dollar, in CO₂e | kg CO₂e / $ |
D | Direct emission factors | B summed over gases: CO₂e emitted by the sector itself per dollar of output | kg CO₂e / $ |
N | Total emission factors | D × L, or M summed over gases: CO₂e across the whole supply chain per dollar of purchases | kg CO₂e / $ |
A_margin | Margin coefficients | Trade and transport margins paid to each margin sector per dollar of a commodity at producer price | $ / $ |
φ | Producer share of purchaser price | 1 ÷ (1 + Σ A_margin): converts producer-price factors to purchaser price | $ / $ |
PI | Price index | U.S. BEA chain-type price index for gross output, by sector (2017 = 100) | index |
Draft
Team to confirm the final list and whether any others (e.g., value added, U/V tables) should be introduced (plan §2.4). To be redesigned as one visual card.
