ABSTRACT
The inter-industry flows scheme, which Quesnay used in the Tableau Economique as a type of formula shares acknowledged similarities with the Leontief input-output model. The mainstream Leontief input-output model, i.e. the open system with respect to the final demand, was designed as a tool of economic programming. Almarin Phillips was the first to present the Tableau in the form of an input-output model. In his pioneering contribution, Phillips stressed the existence of two versions of the Tableau, the so-called zig-zag and the formula. Maital split up the landowners' sector into two parts: the row vector of land services that remains in the structural matrix, and the column of final demand that is moved to the right-hand side of the system and replaced with a zero vector. The model is informed by Quesnay's own assumptions, including luxury consumption is the autonomous component of global demand, while the dependent components are the productive investments comprising amortisation, working capital and producers' means of subsistence.
