Impacts of social insurance on firm performance: evidence from Vietnamese small- and medium-sized enterprises

PurposeThis article analyzes the impact of social insurance on firm performance by obtaining evidence from Vietnamese small- and medium-sized enterprises.Design/methodology/approachThe method employed in the research is the generalized method of moments for testing hypotheses of data collected from the General Statistics Office of Vietnam.FindingsThe results show that social insurance contributions can enhance firm performance in three dimensions: return on equity (ROE), labor productivity and total factor productivity (TFP). In addition, financial leverage, firm size, the average wage of workers and fixed assets have an impact on the social insurance costs of these companies.Originality/valueThis article provides a novel explanation of the contribution of social insurance to firm performance. In particular, social insurance contribution not only increases labor productivity but also boosts the growth of the TFP of companies. In addition, the article points out that taking care of the benefits of employees is a valuable investment of companies. These are the unique contributions of the paper to the literature on the economic impact of social insurance.

Bracket Creep Revisited – with and without r > g: Evidence from Germany

Using German income distribution in 2009, this article studies the redistributive and revenue effects of bracket creep under various inflation scenarios. We develop a tax micro-simulation model for the newly available Panel on Household Finance (PHF) data. The simulation yields an inverted U-shaped overall redistributive effect of the income tax and social insurance contribution system with respect to the inflation rate, which contrasts with Immervoll (2005), who finds that fiscal drag always enhances the equalising effect. The nominal income growth as well as the deterioration of tax progression at the middle and top of the income distribution between 1998 and 2009 can be the impetus for this change. This result implies that delaying adjustment might reduce redistribution. We also suggest that these results might not be restricted solely to Germany. Additionally, when we introduce the empirical evidence that capital income grows faster than non-capital income r > g, the dual tax system with a flat capital income tax implemented in 2009 further disequalises the after-tax income substantially. Allowing inflation compensation to lean towards the poor by boosting their share of capital income may not be favourable to redistribution.
