This report presents the results of an empirical exercise conducted to provide researchers, local and international alike, with an updated set of I-O data. Previous studies relate to CYs 1978 and 1983. The choice of 1990 as the update year was based solely on the availability of limited but more current information required during the course of the study. I-O version was generated for the 1990 update. The basic table consists of 177 commodity sectors, six final demand and four primary inputs or value-added sectors.
Imports valued at producers prices include CIF plus customs duties and import taxes.
On the whole, the economic aggregates shown in the table are more or less consistent with the national accounts figures for the year under study. Based on these assumptions, the general estimation methodology consisted of two successive operations. These price-adjusted coefficients were then subjected to the modified RAS iterative procedure to account for possible shifts in production and demand structures from CYs 1988 to 1990. One set was used to update the base-year matrix of domestic input coefficients, A 0 d . The other applied to the matrix of imported input coefficients, A 0 m .
