Ringkasan	Input-output multiplier analysis converts the Leontief inverse into summary impact coefficients that answer how much total output, household income, or employment an economy generates per unit of final demand directed at a given sector. Building directly on Leontief's inter-industry accounting, it distinguishes the initial direct effect from the indirect supply-chain effect and, in the Type II form, the induced effect of household re-spending, yielding the multipliers that underpin most regional and project economic-impact studies.	A social accounting matrix (SAM) is a square, double-entry table that records all transactions among the production sectors, factors of production, institutions (households, firms, government), and the rest of the world in an economy for a given year. It extends the input-output table by closing the circular flow of income — connecting how value added becomes factor income, factor income becomes household income, and household income becomes demand — so that every account's receipts (its row) exactly equal its expenditures (its column).
