Leontief

The Leontief production function (1.2) assumes there is only one technique for producing output and requires combination of the inputs in a fixed ratio; the elasticity of substitution is zero.

Leontief (1971) argued that econometrics was an attempt to use more and more sophisticated statistical techniques to compensate for the glaring weakness of the database available.

In the thirties Wassily Leontief published his essay "Quantitative Input-Output relations in the economic system of the United States" (1936).

The input-output (I-O) model, originally based on the work of Leontief, captures the interrelationship across industries using transaction matrices (Miller and Blair 2009).

The existing mainstream thinking came into serious scrutiny with the work of Wassily Leontief who studied the structure of the United States foreign trade and asserted that the previous principles and assumptions did not hold.

In the 1980s, gross output statistics were published every five years as part of the input-output (I-O) tables developed by economist Wassily Leontief. According to Leontief, the I-O accounts required examining the "intervening steps" between inputs and outputs in the production process, "a complex series of transactions ...

These technical coefficients were kept fixed for the proposed cost model, configuring a Leontief production function (Leontief, 1936).
