Updating and estimating a social accounting matrix real dating reviews
Since the input-output accounts are contained within the SAM framework, updating an input-output table can be viewed as a special case of the general SAM estimation problem.The paper presents the structure of a SAM and a mathematical description of the estimation problem.The traditional RAS approach requires that we start with a consistent SAM for a particular year and “update” it for a later year given new information on row and column sums.This paper extends the RAS method by proposing a flexible “cross entropy” approach to estimating a consistent SAM starting from inconsistent data estimated with error, a common experience in many countries.This paper offers a social accounting matrix (SAM) based analysis leading to a better understanding of the way various agents in the real economy interact, the way socio-economic groups make their living, the channels through which demand driven interventions may affect the poor, and the potential growth-poverty-inequality nexus. First, the paper reveals the economic structure of Bangladesh with a SAM framework where the macro (national accounts and input-output table) and micro (national surveys) data are juxtaposed under a unified data matrix to portray the meso level interactions of various economic agents, that is production sectors, factors of production, household groups, and other institutions.

Subsequently, the SAM is used to develop a multiplier simulation model, which enables tracking and quantifying the nature and extent of the linkages among the demand driven shocks (stimuli), economic growth, income generation, and concomitant poverty and distribution implications from the perspective of different socio-economic groups in Bangladesh.
