Income Distribution in a Regional Economy: A SAM Model

Social accounting matrices (SAM) are a numerical scheme of the circular flow. The SAM-based multipliers can be used to determine the changes in the relative income of the economic agents. In this paper we investigate the process of income distribution in the Catalan Economy, using the linear model of SAM multipliers. We also present an additive decomposition of the distributional incidence measurement provided by Roland-Holst and Sancho (1992). With this decomposition we can identify the different components in the overall process of income distribution among the agents of an economy. The proposed approach pays special attention to the role of the government in the process of income distribution.
