"Constructing input-output tables and a CGE database for Afghanistan" by Ahmadzai, Khwaja Muhammad, Joseph Francois, Octavio Fernández-Amador and Patrick Tomberger Abstract Creating a database consistent with Global Trade Analysis Project (GTAP) and to be functional as a Computable General Equilibrium (CGE) database is problematic and requires a considerable amount of information and a number of data manipulation steps. Therefore, very few articles provide details about the database creation process. With such purpose, in this paper, we describe and document numerous aspects of constructing a Social Accounting Matrix (SAM) for a single country ( i.e. developing country). In order to obtain our objectives, we introduce Conversion and projection methods and use Afghanistan as the case study. The conversion method converts the 2017 Afghanistan Supply and Use table into a CGE database. The projection method project the IO tables and SAM from 2016 and 2019 backward to estimate the SAM for the remaining GTAP reference years (2014, 2011, 2007, 2004). This method is based on the Compound Annual Growth Rate (CAGR). It is likely that as we project the required matrices we violate the balancing condition. Therefore, we use generalized iterative scaling method (KRAS) to ensure that the balancing condition holds. There are four main contributions of this paper: First, the construction of the first Afghanistan IO tables (65 sectors) for the year 2017 and, subsequently, the first Afghanistan SAM. Second, Backward projection of the SAM from 2016 and 2019 in order to obtain SAM for the remaining GTAP reference years. The method we developed can also be used for forward projection, imputing missing wages, and updating and estimating employment data. Third, integrate Afghanistan into the GTAP Data Base. Fourth, even though these conversion and projection methods have been applied to the case of Afghanistan, we document data compilation procedures such that our approaches can be easily applied to create other countries or regions. |
