Empirical Analysis of Fiscal Soundness and Public Social Expenditure: A Lesson for the Future Direction of the Korean Welfare State

The aim of this paper is to investigate the relations between fiscal soundness and public social expenditure in advanced welfare states so as to reconsider the conventional wisdom that welfare expenditure aggravates national finances. Through this, I propose the clues of building the sustainable Korean welfare state. I focus on the interdependent relationship between fiscal soundness and public social expenditure based on fiscal sociology. Considering this interaction, I form two sets of simultaneous equations models and employ a special statistical method, three‐stage least squares (3SLS). The results regarding the causal relationship between fiscal soundness and public social spending indicate that, if public welfare spending is increased, fiscal health is damaged. However, as many comparative social policy researchers have pointed out, outcomes of welfare states differ from country to country according to the composition of public welfare spending. Specifically, some welfare states with priority given to social services such as vocational training or childcare services have maintained the stability of public finance. By extension, we can say that public social expenditures have a positive influence on fiscal soundness based on the composition of social expenditures. Finally, it is possible to create financially sustainable welfare states.
