Using Almon\'s Mathematical Algorithm for Eliminating Negative Elements in Symmetric Input – Output Table

Abstract

In this paper, we construct a Symmetric Input-Output Table (SIOT), which has no negative elements and preserves balance of table. For this purpose, we apply Almon's mathematical algorithm and use the Make and Use Matrices of 2001, which are provided by the Statistical Center of Iran (SCI). The estimated SIOT is compared with the SIOT of SCI. Our findings reveal that required adjustments in SIOT derived by Almon's algorithm are less than adjustments made by the SCI for eliminating negative elements. We propose this method for the calculation of future Input-output Tables of Iran.
