Methods of Revising and Demonstrating the Amended Input-Output Table of the Central Bank of I.R.I for the Period of 2010-2011

Compiling and collection of Input-Output Tables within the short interval of time which are prima facie deemed as one the principal apparatus of economic analysis have been contemplated per se with special significance in the compilation of national accounts systems in toto.
In actual practice, the compilation of Input-Output Tables could take place in two procedures i.e. 1-Employing the statistical approach and 2-Applying the semi statistical methods.
It is an axiomatic fact that , since the compilation of statistical tables requires the collection of large volume of data and also implementation of heavy census surveys, the collection and accessibility to these data are de facto time consuming and cost-incentive, pro rata. Besides, the desideratum of countries to compile the Input-Output Tables to avail the more transparent impression for the real sectors of the economy, could pave the way to expound that recognition of dynamic relations between the real activities of any economy are inevitable. Thus, after compiling a comprehensive statistical Input-Output Tables, we can utilize the various statistical techniques to revise them, Ipso facto. It goes without saying that, many international organizations have attempted in their agenda to revamp the concerned Input-Output Tables viz-a-viz applying the intermediate solution to address the issue of time lag and cost insentiveness, Sui generis.
In Iran, the Input-Output Table of (2004-2005) was de jure, considered as the latest table published by the Central Bank of I.R.I, which was designed based on the latest guidelines of the United Nations Input-Output Table issued in 1999 and also the National Accounts System published in 1993 and 2008 respectively. This table comprises the supply and use table, containing the 108 products to 52 economic activities. In addition, it includes a symmetric table of 52 to 52 activities with assumption of activity technology. Hence, dealing with this table which is derived on the basis of fixed prices, we have tried to revise the Input-Output Table of (2010-2011), that is a symmetric table with 52 to 52 activities and assuming the technology of activity, Sine qua non.
