A Study on the Income Flow of Welfare Policy: Multiplier Decomposition and Structural Path Analysis in a SAM Structure

Abstract

The argument that “social welfare is a free lunch” implies that welfare damages fiscal sustainability of government and hinders economic growth. Using a ‘social accounting matrix’ (SAM) associated with the fixed-price multiplier decomposition and structural path analysis, we figured out the effects of welfare policy on the income and redistribution. First, it is shown that the direct government transfer to the low-income households does improve income inequality, while the investment of same amount of money to the production activities produces more income. That is, in terms of production activities, there is an opportunity cost in transfers to the low-income households. Second, if the injection occurs in social welfare sectors as production activities, elementary paths originating with that activity would affect factor demand before the influence is transmitted to the households. This implies the importance of primary income associated with wage, when improving household income. Third, the investment on production sectors such as health and medical services and social welfare service increases more household income and, at the same time, improves income redistribution, relative to the investment on other production sectors. Social welfare is “not” a free lunch. We should focus our concern on whether the welfare expenditure contributes to the improvement of income inequality.
