Abstract
The paper describes several new methods of updating Input–Output matrices. The deficiency of the conventional methods of updating these matrices is that they do not make much use of the commonly available interindustry data and thus exhaust only a small number of the available degrees of freedom. The updating methods described here are based on consistency relationships derived from the Leontief output and price systems. Thereby these methods bring substantially more interindustry data to bear on the updating process, and consequently give rise to better Input–Output coefficient estimates.Keywords
