Social Accounting Matrices and Economic Modelling
2003A Social Accounting Matrix (SAM) is a comprehensive, economy-wide database that contains information about the flow of resources associated with all transactions that have taken place between economic agents in an economy during a given period of time.

Balancing Social Accounting Matrices with Artificial Polymorphus Ants [PDF]
Computational Economics, 2014 An artificial ant colony algorithm is proposed for balancing a social accounting matrix. The approach is based on the swarm behaviour of ants, which choose an optimal path between their colony and the source of food by leaving a trace of pheromones. In the algorithms, an improvement in the balance increases the pheromones, thus rising the probability ...

The Estimation of Large Social Account Matrices
Journal of the Royal Statistical Society. Series A (General), 1978Formalization and extension of a recent proposal for adjusting initial unbalanced estimates of components of a matrix allows them to satisfy accounting requirements imposed by tabular form in an optimal manner. The proposal, which is based on linear combinations of initial unbiased estimates, has many potential applications in national income ...

Social accounting matrices and social accounting analysis
2017This chapter shows how the Social Accounting Matrix (SAM) framework can be used to provide the initial conditions and help calibrate an applied general equilibrium model. The genesis of the SAM goes back to Richard Stone's pioneering work on social accounts. The SAM is both a data system and a conceptual framework useful for policy analysis.

Using Social Accounting Matrices to Account for Distortions in Non-market Economies
Economic Systems Research, 1991The use of non-market mechanisms for allocation and distribution gives rise to hidden flows (rents) not captured in market-based national statistical sources. This paper develops an operational framework for quantifying the magnitude of these hidden flows and their percolation throughout the economy. The price-equivalents of the non-market controls are

Balancing large social accounting matrices with nonlinear network programming
Networks, 1989AbstractWe formulate the problem of optimally adjusting the components of a large matrix to satisfy consistency requirements as a nonlinear network optimization model. An efficient network optimization algorithm—GENOS—is incorporated in a user friendly modeling system—GAMS.

POVERTY-FOCUSED SOCIAL ACCOUNTING MATRICES FOR TANZANIA
2003The development of effective and sustainable economic policies for Tanzania requires access to appropriate databases. One such database is a social accounting matrix (SAM) that details the structure of the entire economy, taking into account the patterns of production and demand, and various institutional relationships.

Social Accounting Matrices: Challenges and Prospects of Use in Macroeconomic Statistics
Voprosy statistiki, 2023The paper presents results of the first stage of research on the construction of social accounting matrices (SAMs) for the Russian Federation as part of the HSE University study on statistical assessment of households’ economic behaviour. The author analyses the methodological foun- dations of SAM compilation, their connection with the System of ...
