ABSTRACT
By way of introduction it can be stated that the social accounting matrix, SAM, is compiled according to the same accounting principles as inputoutput tables, each transaction being recorded twice so that any ingoing in one account must be balanced by an outgoing of another account. However, the SAM contains a complete list of transactions describing income, expenditure and production flows among sectors, factors of production and groups of households. These transactions are usually grouped into several sets of accounts belonging to various economic agents, as will be elaborated later.
