Taking into consideration the recent debates on adopting a progressive tax system over the flat-rate taxation, our paper aims to investigate the impact of a change in the current Romanian personal income tax policy system from the 10% flat-rate tax system to some alternative progressive taxation scenarios. The methodological approach consisted in using the European Union Survey on Income and Living Conditions (EU-SILC) database to micro-simulate the impact upon poverty and income inequality. Through our ex-ante tax policy analysis we bring empirical evidence of a modest, but positive effect upon poverty rate and income inequalities in favor of a progressive taxation system. However, when looking at the government financial implications through the personal income tax budget revenues, we discuss upon the possible trade-off between the benefits on poverty and income inequalities and the possible budgetary drawbacks. Despite the data limitations, this study has the benefit of being among the first attempts to evaluate the impact of a personal income tax policy reform for the case of Romania.
Abstract:In the aftermath of Angola's civil war, strong economic relations developed between the country and the People's Republic of China. Our study addresses China's investment risks in Angola, considering an infrastructure-for-petroleum partnership between these two countries. The main working hypothesis is that the recovery of Chinese investments made in Angola is has translated into thousands of barrels of petroleum being imported daily from Angola. We analyzed the main economic, social, and political indicators that describe the situation in Angola that could impact the recovery of Chinese loans in the form of oil exports. Data processing implied involved regression-based imputation, MinMax data normalization, the use of the Analytical Hierarchy Process (AHP), and econometric analysis, next to the construction of a composite risk indicator. The results of the econometric analysis highlighted that an increase in the composite risk indicator of 1% leads to a decrease in the quantity of petroleum exported by almost 6377 barrels per day. Because, at least in the short run, the economic diversification in Angola is weak, and the most important asset is its oil, the partnership with China will continue to exist. This cooperation model represents a source of economic growth and infrastructure development for Angola and a source of energy that fuels China-one of the most powerful economies in the world.
