This publication is a part of the IPS research programme on “Economy-Wide Modelling for Policy Analysis”, and presents a detailed Input-Output (I-O) table and other associated tables (import matrix, direct coefficient matrix, and the Leontief inverse) for Sri Lanka compiled for the year 2000. The main I-O table presents a detailed structure or the “snap-shot” of the Sri Lankan economy. Government statistical offices and research institutions in many developed and developing countries compile I-O tables for their economies at regular intervals as a national statistical requirement and for the purpose of providing detailed databases for policy analysis as well as economy-wide modelling. Unfortunately, the compilation of I-O tables for the Sri Lankan economy has been irregular even though the history of compiling I-O tables for the Sri Lankan economy goes back to the 1960s. This has been one of the most neglected areas of research in recent years. This has also been a main constraint in developing an economy-wide model for policy analysis. This publication represents the first time in two decades that I-O tables for Sri Lanka have been released with a detailed document on the procedures of compilation with an electronic version of I-O tables.
