The methodology to construct social accounting matrix for Ukrainian economy
The paper proposes a methodology of social accounting matrix construction on the basis of available data in the system national accounts of Ukraine. It is consistent with the main principles of such matrix organization concerning the balance, content and structure of accounts, which enables its use in classical problem statements with general equilibrium models. The methodology provides the necessary disaggregation level of matrix blocks for modeling the links between production processes, use of resources and financial flows, which gives the possibility to take into account the process of transformation of savings into capital assets. The proposed methodology is universal and may be used in case of changing the classifiers of economic activities, in particular, during the transition to CEA 2010. Formal presentation of the matrix elements simplifies the automation of the process of matrix construction, which, with the appearance of new statistical data, allows quick renewal of the matrix. Its representation in the form of a sum of matrix with data of individual accounts allows easy operation with them during further modeling with standard packages like MathLab, R or GAMS. The experimental calculation of the matrix of social accounts for Ukraine was done for 2011. The estimates demonstrate that the use of the above mentioned methodology ensures a proper balance of the matrix account and does not require additional balancing procedures. That ensures the absence of discrepancies between the matrix data and the actual indicators of the national accounts.
