Comparative Analysis of Statistical Errors Between Second and Third Types of Input-Output Tables and Their Correlation with Value-Added in Gross Exports

In this article, we introduce three types of input-output tables and modify a central bank table from 2016 to illustrate the transition from the first generation of statistical bases to the second generation, which meets the new international trade theory’s database requirements. The third type of table is critical and is considered the starting point for such changes. Given the lack of such a table in Iran, this article offers three challenges, followed by three critical questions: first, what can be done if official compilers do not attempt to develop such an input-output table soon? Second, which of the two types of tables has more statistical errors than the modified tables? Third, which of the two input-output tables is better for measuring value-added content in gross exports? The central bank's most recent SUT and intermediate import utilization data from 2016 are utilized to investigate three questions. The data show that: calculating the third type of table can solve this lack of statistics. In comparison to the second table, the third table exhibits fewer statistical mistakes. Finally, the third type of table outperforms the second in terms of quantifying value-added content in gross exports.
