The Role of Income Tax Progressivity in GDP Smoothening: Empirical Analysis
Žofák, Pavel ; Baxa, Jaromír (advisor) ; Cahlík, Tomáš (referee)
This thesis studies the relationship of income tax progressivity and output volatility. Using our dataset of 31 OECD countries and Bayesian model averaging (BMA) approach to address the model uncertainty issue, we find positive evidence that higher income tax progressivity leads to lower output volatility. This effect is robust to different prior specifications in BMA and to different tax progressivity measures, including our newly constructed measure which is based on the slope of the average tax curve. We also find a strong effect of tax progressivity on the consumption volatility and the volatility of hours worked which we see as the main channels for the reducing effect of tax progressivity on output volatility.
The impact of tax-benefit system on the labour market
Žofák, Pavel ; Pertold-Gebicka, Barbara (advisor) ; Kosturák, Matej (referee)
This thesis assesses the impact of taxes and unemployment benefits on the unem- ployment rates. The aim of the thesis is to find determinants of tax-benefit system which influence the unemployment rate and how much they do so. This issue is studied both theoretically and empirically. The empirical part is built on the panel dataset of 28 OECD countries which covers the period between 2005 and 2012. The main influence on unemployment is ascribed to the labour taxes which drives the wedge between the labour costs and the net income of the worker. On the other hand, the consumption tax seems to be neutral in determining the unemployment rates and the impact of benefit levels crucially depends on the way they are taxed and on the eligibility criteria. Whole tax-benefit system impacts rather the long- term unemployment rates than the overall unemployment.
