Updating and estimating a social accounting matrix Sim dating games for adults
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. (2000): Social Accounting Matrix-Based Modelling: Extension to Wellbeing and Environment and Computable General Equilibrium Models (applications using the 19 Ecuador SAMs). 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.

The traditional RAS approach requires that we start with a consistent SAM for a particular period and “update” it for a later period given new information on row and column sums.This paper extends the RAS method by proposing a flexible entropy difference approach to estimating a consistent SAM starting from inconsistent data estimated with error, a common experience in many countries.

Typically, input-output data are collected at long intervals (usually five years or more), while national income and product data are available annually, but with a lag.
This work involves the construction of the 2013 Social Accounting Matrix for the D. Given the nature of these data, we have resorted to the bottom-up approach to the development of this SAM and methods of RAS and cross-entropy for its balancing. 1997, «Entropy optimisation methods for the estimation of tables», Classification, Data Analysis and Data Highways, p.
The method is flexible and powerful when dealing with scattered and inconsistent data.
It allows incorporating errors in variables, inequality constraints, and prior knowledge about any part of the SAM (not just row and column sums).
There is a continuing need to use recent and consistent multisectoral economic data to support policy analysis and the development of economywide models.
Updating and estimating input-output tables and Social Accounting Matrices (SAMs) for a recent year is a difficult and a challenging problem.
