In the last fifty years, many countries have moved toward broad-based and flat-rate tax systems such as the value-added tax (VAT) and the flat-rate income tax. The main rationale for introducing a broad-based and flat-rate tax system is the belief that such a system increases the incentive to work, save, and invest, leading to a higher aggregate income and a higher standard of living. Yet, empirical evidence on the actual effectiveness of broad-based and flat-rate taxes is very limited. This dissertation combines novel methodologies with newly available data to provide causal estimates of the economic effects of broad-based and flat-rate tax systems. The first essay analyzes the impact of the flat tax reforms on GDP per capita and its main drivers. I identify 8 Eastern and Central European countries that adopted flat tax systems between 1994 and 2005 and apply synthetic control methods to estimate their counterfactual trajectory of GDP per worker in the absence of a flat tax. I find positive impacts in all 8 countries, with 7 out of 8 cases significant at the conventional level. The second essay estimates the efficiency gains of adopting a VAT in a worldwide sample of countries using synthetic control methods. I find that the VAT has, on average, positive and economically meaningful impact on economic efficiency. However, I find that this result is driven by richer countries only. There is no significant impact of the VAT on poorer countries. I find similar results when estimating the impact of the VAT on total factor productivity and capital stock per worker â"u20ac"u201c two important channels through which a VAT affects economic efficiency. The third essay estimates the causal impact of a VAT on productivity, capital accumulation, and input cost using Regression Discontinuity Design and firm-level data from France. I find no significant impact of a VAT on firms' productivity or input cost. However, I find some evidence that the VAT increases firms' capital accumulation. In addition, I also find that the impact of a VAT is heterogeneous across different sectors of the economy. / Bibek Adhikari
