Social Accounting Matrices

UNU-WIDER provides Social Accounting Matrices for South AfricaMozambique, Viet Nam, and Zimbabwe.

A SAM is a consistent data framework that captures the information contained in the national income and product accounts and a supply-use table (SUT), as well as the monetary flows between institutions. Since is an ex-post accounting framework, within its square matrix, total receipts must equal total payments for each account reported by the SAM.

The required data is drawn from various sources and must therefore be compiled and made consistent. This process is valuable since it helps identify inconsistencies among statistical sources.

For example, there are invariably differences between the incomes and expenditures reported in national household surveys and national accounts. SAMs are economy-wide databases which are used in conjunction with analytical techniques to strengthen the evidence underlying policy decisions.

Multiplier analysis as a method of examining impact of the COVID-19 pandemic

Multiplier analysis is one method for examining the impacts of the COVID-19 lockdowns, particularly in the short run when both prices and technology are relatively fixed. The SA-TIED technical report 'Modelling the effects of COVID-19 on the South African economy – a technical guide to the scenario builder' provides a guide to an economywide model that applies the approach to South Africa in the context of COVID-19 pandemic by using a social accounting matrix. The report and associated excel files provide an overview of the approach and gives the author a detailed guidance on application of the framework implemented in Microsoft Excel.
