27: Leontief Input-Output Model - Texas A&M University
The Leontief Input-Output Model can be described by the equation X = AX +D where X is the production matrix (total output), A is the input-output matrix and D is the consumer demand matrix The calculation AX = X ¡ D is the internal use of the model The production matrix can be solved by the formula: X = (I ¡A)¡1D: °

Aggregation in Leontief Matrices and the Labour Theory of Value
as a by-product of the analysis of Leontief matrices It has been shown,2 for instance, that in a Leontief model the price of a commodity in terms of labour ("wage-price") will equal its Marxian "value" under certain conditions which include (i) competitive long-run equilibrium, i e , zero profits in each
The Leontief Open Model Leontief Open Model
The Leontief Open Model The Leontief Open Model is a simpli ed economic model for an economy in which consump-tion equals production, or input equals output Internal Consumption (or internal demand) is de ned to be the amount of production consumed within the industries themselves, whereas
Leontief Input-Output Model
Leontief Input-Output Model We suppose the economy to be divided into nsectors (about 500 for Leontief’s model) The demand vector d~2Rn is the vector whose ith component is the value (in dollars, say) of production of sector idemanded
A Note on Exchange Market Equilibria with Leontief’s Utility
Arrow-Debreu problem with Leontief’s utilities, a more di–cult exchange market problem, is the Perron-Frobenius eigen-vector to a scaled Leontief utility matrix, and the equilibrium vector is a solution to a system of linear equations and inequalities of the original data
