Impact of tax rates on tax revenue for the state – modeling of Laffer curve
Šmejkal, Martin ; Soukup, Jindřich (advisor) ; Makovský, Petr (referee)
There are many recent studies which try to find the evidence of the Laffer curve in national economies or aggregated OECD data. In this Master Thesis I focus on testing of the primary linear relation of the corporate income tax rate and the corporate tax base, that I call herein adjusted Laffer curve. The adjusted Laffer curve is then transferred through the simplification into the ordinary Laffer curve. The linear regression analysis is performed on the OECD data of 34 countries across years 2000 to 2014. Firstly, the countries are split by the national tax system criteria, such as tax quota, tax revenue allocation or tax structure of revenues that I consider essential for further analysis. Based on the results of linear regression I can only find Laffer curve in set of countries that aim to collect tax revenues mainly from direct taxes. However, there are also other major findings, such as the fact that negative relation of the corporate income tax rate and the corporate tax base, can be found in countries with the higher tax quota, while not in those with the lower tax quota.

Validation of selected economic theories on macroeconomic data for the Czech Republic
Zoul, Lukáš ; Mirvald, Michal (advisor) ; Matula, Miloš (referee)
The main goal of the thesis is to explore selected economical hypotheses through theoretical conception applying macroeconomics data from the Czech Republic. This thesis includes the following hypotheses: budget deficits solved by increasing taxes, compromise between unemployment and inflation, low impact of budget deficits. To verify these hypotheses, there is a comparison with economic theories such as Laffer curve, which has showed that Laffer peak is at the level of 22 % taxation. Other used theory is the Phillips curve where correlation between inflation and unemployment rate is stronger based on yearly data than on monthly data. Theoretical model IS-LM has confirmed that multiplication effect could have caused the positive economic growth in 2010 and 2011. Even if economical hypothesizes are partially correct, they are not recommended for the government to determine their decisions. There are more efficient long-term solutions that can be used to solve challenges of the recent economic situation.

Optimal Alcohol Taxation in the Czech Republic according to the Laffer Curve Theory
Šebestová, Tereza ; Janíčko, Martin (advisor) ; Slaný, Martin (referee)
This bachelor thesis examines the relationship of excise duties on spirits and beer and its revenues in the Czech Republic from 1994 to 2014 according to the Laffer Curve theory and tries to find the optimal tax point using the regression analysis. Optimal taxation is defined in order to be revenue-maximising. According to this requirement I defined the optimal taxation on spirits at the rate 17 035 CZK/hl/pure alcohol and the optimal taxation on beer at the rate cca 27/CZK/degree Plato. Both of these rates lie on the left side of the current taxation and therefore I claim that the tax burden is too high and its decline would brings the state higher revenues.

Analysis of Value Added Tax Revenues in the Czech Republic: a Case Study
Rottová, Tereza ; Ježek, Tomáš (advisor) ; Řežábek, Pavel (referee)
The analysis of data from the Czech Republic between 1993 and 2013 assesses how VAT rate changes impact VAT revenues of respective national budgets. The core focus of the paper is the application of the Laffer curve on value added tax. Using a regression analysis we analyze how VAT revenue contributions to the budget are impacted by GDP. The results of our econometric model impaly that a 1% GDP increase leads to a 0.987% increase in VAT revenues to the budget. We find, by cleansing the VAT revenue data of inflationary and GDP effects, that the highest income generating VAT rates are 23% standard and 5% reduced. Both rates were, however, in effect as a result of VAT introductions in the Czech Republic, which might lead to a significant bias in our analysis. We present a chart of a time series of VAT revenues adjusted for inflationary and GDP effects which shows that VAT revenues decrease in the period from 1993 to 1998 after which they stabilize at around CZK 40bn until 2013. From that we infer that, over time, VAT payers have learned how to avoid the tax. We also present three hypotheses in our work; we find that an increase in the reduced VAT rate always brings additional revenues to the budget, that standard VAT rate changes impact revenues in the same direction in only 3 out of 5 cases, and that standard VAT rate changes are a leading variable for household consumption, the trend of which is always less volatile as the lagging variable. The above applies for the reduced VAT rate in just one of four cases.

Provisions of Czech republic to reduction of incidence fo crisis on Czech republic
Kopáček, Jiří ; Mirvald, Michal (advisor) ; Bartoň, Petr (referee)
The aim of my bachelor thesis is to analyse anti-crisis provisions of National economic council of government (NERV). I confront the provisions with reality and try to find out, if the provisions are effective or not for now. Proposed provisions, which I devote in the thesis are concerned in changes in payment of insurance of employee and tax liability of firms. The thesis is devided into three main parts. In the first part I shortly devote to causes of financial and economic crisis and consequent establishment of government advisory authority -- NERV. Main topic in this part is change in payment of insurance of employee. To find out of effect of these provisions I use correlation analysis. In the second part I am engaged in change of tax rate of corporation tax. I use theories of economists of supply side (Arthur Laffer). The biggest attention I pay to Laffer curve, which I demonstrate for Czech republic. Final third part of thesis represents effect thereinbefore mentioned provisions on employment in CR, which I then compare with employment in EU.

Size of tax rates in relation to the tax revenue
Frey, Marek ; Vokoun, Marek (advisor) ; Vebrová, Ludmila (referee)
This thesis examines the question of adjusting the size of tax rates in relation to the tax revenue on a sample of EU countries and on the example of the Czech Republic. Research is hold thanks to the Eurostat statistics related to the reporting on the implicit tax rates of capital, labour and consumption allowing us for an international comparison for the period from 1995 to 2008. Thanks to the Components of total tax revenue growth analysis and Regression analysis of tax revenue we shed some light on investigation of current understanding and interpretation of the issues of taxation, tax competition within the EU and the avoidance of excise taxes, taxes on labour and capital. Our results suggest that there are Laffer curves with decreasing returns to scale in case of excise taxes, taxes on capital. In case of labour taxes there seems to be complicated relationship, however, in one of the models traditional-like curve were introduced. If we change the tax rates on capital we can most probably expect decreased tax return between two years but further investigation to this issue is needed.

The Laffer curve and its application in practice
Kadlecová, Lucie ; Mirvald, Michal (advisor) ; Babin, Jan (referee)
This paper aims answer the question what is the revenue--maximizing rate of corporate income tax. Before analysis the literature of Laffer curve criticism and conversly literature of Laffer curve applications is summarized. In paper the relationship of tax rates and tax revenues is examined for Czech republic in time period from 1993 to 2009 and for Ireland in time period from 1981 to 2009 by regression analysis. Analysis showed the relationship described by Laffer theory. Revenue--maximizing tax rates reach values of 27,66% for Czech Republic and 25,1% for Ireland. Because the current statutory corporate tax rates are in both countries lower than calculated Laffer points, further reduction in tax rates will result in decline in tax revenues.
