A fair-biased allocation of investment between economic sectors using social accounting matrix multiplier analysis

Economists have exploited the social accounting matrix in linear economic models to analyze the effect of some variables such as government spending, investment, and export on other economic indicators including total output, employment, household income, and economic growth. In this paper, the influence of investment injection on some economic indicators is analyzed. In addition, to gather different indicators in a general view, these economic indicators are applied as inputs and outputs in a data envelopment analysis model. Overall, to get to the best possible economic conditions, a fair revenue allocation method is used based on a data envelopment analysis model to determine each economic sector’s quota of investment. Next, a kind of fair-biased allocation method improving the economic conditions in comparison to the prior model is proposed. Finally, the whole process for Iran’s social accounting matrix and subsequent results are presented.
