The changes in the institutional framework of the Brazilian oil industry were considered, since the Petrobras´s creation to the discovery of pre-salt areas, with details of the Petroleum Law (Law No. 9.478/97) established the royalties in Brazil. With emphasis on municipal revenues, highlighted the relevance of the study in relation to Rio de Janeiro municipalities for being the largest collectors of royalties and special participation in Brazil. Then, using the economic theory of natural resources were analyzed theoretical foundations in Hotelling and Hartwick for the use of revenues from exploitation of natural resources. Complementing the theoretical framework, they were listed the reasons for the presence of resource curse theory. To assess the royalties´s impact in Rio de Janeiro municipalities, statistically significant, the study was performed in two different stages. The first applied the panel regression method in the municipalities that are beneficiaries of the oil and gas revenues; and the second was made with analysis of specific data of the municipalities with greater dependence on royalty revenue versus the municipalities that are not beneficiaries of such revenue. / Esta dissertação tem por finalidade avaliar o impacto das receitas de royalties e participações especiais referentes à exploração e produção de petróleo e gás natural nos 87 municípios beneficiários do Estado do Rio de Janeiro, com base em indicadores socioeconômicos no período de 2000-2013. Foram analisadas as mudanças ocorridas no quadro institucional da indústria petrolífera brasileira, desde a criação da Petrobrás até a descoberta das áreas de pré-sal, com detalhamento da Lei do Petróleo (Lei nº 9.478/97) que instituiu os royalties no Brasil. Com ênfase às receitas municipais, destacou-se a relevância do estudo em relação aos municípios fluminenses por serem os maiores arrecadadores de royalties e participações especiais no Brasil. Em seguida, utilizando-se da teoria da economia dos recursos naturais, foram analisados fundamentos teóricos em Hotelling e Hartwick para utilização das receitas provenientes de exploração de recursos naturais. Complementando o marco teórico, foram elencados os motivos para presença da teoria da maldição dos recursos naturais. Para avaliar o impacto das receitas de royalties e participações especiais nos municípios fluminenses, de forma estatisticamente significativa, foi executado o estudo em duas etapas diferentes. Na primeira aplicou-se o método de regressão em painel nos municípios que são beneficiários das receitas de petróleo e gás; e a segunda foi feita com análise dos dados específicos dos municípios com maior dependência de receita de royalties e participações especiais versus os municípios que não são beneficiários de tal receita.

本文以美國境內航空市場為例，探討多重市場接觸與價格離散的關聯，並研究大型航空公司併購案前後多重市場接觸對航空公司競爭策略的影響。本研究發現：(一) 相互容忍說於併購案發生前後皆成立。(二) 相較於考量擴大市場的市佔率，航空公司更應該關注與競爭者間的競爭關係。(三) 併購案發生前後，航空公司的訂價行為都深受競爭對手的競爭策略影響。(四) 併購案發生前，因競爭者多，市場上航空公司平均市佔率的大小是航空公司可採取競爭手段重要因素之一。在最大的1000 個市場中，雖然每家航空公司的市場力量不大，航空公司仍可採取價格競爭，然若是對手間聯合懲罰，則航空公司不敢採取激進手段，且多重市場接觸越多，價格離散程度越大。而在次要競爭的市場中，則因航空公司的平均市占率是最大的1000 個市場的兩倍，因此航空公司並未有明顯競爭行為。但若考量競爭對手間的碰面次數，則多重市場接觸與不同分位價格關係為正，且多重市場接觸越多，價格離散程度越低。併購案發生後，因航空公司間彼此箝制力量大，與競爭對手間的碰面次數越多，越傾向隱性勾結，且高價位的價格上升較低價位價格多，使價格離散程度越大。 / In this paper, we discuss whether multimarket contact matters for price dispersion in the U.S. airline industry, and compare the influence of multimarket contact on airlines’ competition strategies before and after airline mergers and acquisitions. We find that: (a) Before and after the mergers, mutual forbearance exists. (b) In contrast to an airline‘s market share, the relationship between airlines and itself plays a more important role in its pricing strategy.(c) Before and after the mergers, airline companies’pricing strategies are significantly affected by their competitors’strategies. (d) Before the mergers, because of the intense competition, it is the size of the competitors‘ market share that the company decide whether to take aggressive strategies. In the top 1000 competitive markets,airline companies will take aggressive actions to get more passengers for the punishment from its competitor is an incredible threat, however, if competitors collude together, airline companies will hardly dare to cut price. And the effect of an increase in multimarket contact on price dispersion is positive and significant. In the second competitive markets, since the average market share is twice bigger than in the top 1000 markets, airlines prefer not to participate in cut-throat competition. However, if competitors collude, then airline companies will cooperate together, and the effect of an increase in multimarket contact on price dispersion is negative and significant. After the mergers, increase in contacts with competitors would facilitate mutual forbearance and increase price dispersion and higher-percentile prices will increase more than lower-percentile prices.

The thesis analyzes and compares tax burden on employees in the Czech Republic and Belgium. The first part summarizes the tax systems of the two countries, and describes how to proceed in the calculation of their tax burden. The second part deals with the comparison of effective tax rates for different types of taxpayers. The third part discusses the tax progressivity in terms of local progressivity, which is measured by using provided intervals and determines for which income categories is the progressivity most important. Lorenz curve in the last part shows graphically global tax progressivity and redistribution of income in society. The Gini coefficient measures it. Final evaluation highlights the important ties between the two countries, compares with other countries of the European Union and its future development especially in the area of taxation of wages.

The purpose of the master thesis is to compare the tax burden of employees in the Czech Republic and in the United States of America according to the legislation in 2016. The theoretical part is devoted to the description of tax systems, focusing on the taxation of income from employment. In the part United States I briefly mention the development of the tax system. The practical part consists of two chapters. The first one is focused on the calculation of the effective tax rate for taxpayers from selected types of households. The second one deals with global progressivity of the income tax. Equal income distribution in society is analyzed using the Lorenz curve and the Gini coefficient. The calculations indicate progressive tax effects both in the Czech Republic and in the United States with higher rate of tax progression and also higher inequality of income distribution in the United States. In the issue of effective rates of income tax is evident higher tax burden in the United States. Differences of total effective rates are decreasing between both countries.

The aim of this thesis is to show how the unconventional monetary policy rounds of Quantitative Easing introduced in the United States between 2008 and 2014 have led to an increase in wealth inequality. The need for the thesis arises due to the uncharted nature of QE and because of more and more information is surfacing to light which points to this connection. By analysing the distribution of these funds and adding it to the then base distribution of money supply, this study was able to determine a significant 10 % increase in the Gini Index. Furthermore it highlights how a large portion of wealth was transferred from the middle class over to the top 5 % income households. Starting from a set of assumptions the calculation is performed by extrapolating the data required and by isolating the system from any external variables. The result is a theoretical model meant to describe the mechanism that links Quantitative Easing to wealth inequality. Moreover a detailed comparison is provided with the effect of a conventional monetary policy such as Open-Market Operations. Finally solutions to this issue are being discussed from economical, political and fiscal standpoints.

The thesis is focused on the exploration of income inequality among citizens of the Czech Republic and Great Britain. It is a comparison that evaluates the state income redistribution through state social support benefits. It provides information, in which country exists greater income inequality in income distribution among households and whether the income inequality among the citizens decreased due to the payment of these benefits or not. The theoretical parts of the work are devoted to explanation of basic terms (such as income redistribution, instruments of redistribution, relationship between social policy and redistribution) and tools for measuring income inequality (Lorenz curve, Gini coefficient, Robin Hood index, Interquintile share ratio S80/S20). The text also describes the various state social support benefits of both countries. The main research section contains calculations and graphical representations of all the above mentioned indicators. The final values are compared and the results are summarized.

This research analyses the statistical relationship between income distribution and seven taxation and government expenditure components in Namibia using data from 1996-2016. The research is aimed at creating new knowledge on the research topic because no literature exists for Namibia. The Autoregressive Distributed Lag (ARDL) cointegration technique was employed to assess the long-run relationship between the dependent and independent variables in Eviews. The research findings indicated that there is no long-run relationship between the dependent variable and independent variables. In the short-run, the research findings indicate that government expenditure on social pensions and government expenditure on education have a balancing effect on income distribution, while tax on products, corporate income tax and customs and excise duties have an unbalancing and/or worsening effect on income distribution. Based on these findings, tertiary education loans are recommended as opposed to grants to ensure sustainability of Namibia Students Financial Assistance Fund (NASFAF). In adjusting corporate and value added taxes, the government is cautioned to avoid overburdening consumers and employees through tax shifting in the form of high prices of goods and services and low wages and benefits. A tax mix, tax discrimination and a hybrid of taxation and government expenditure components are strongly recommended to achieve a balance. / Economics / M. Com. (Economics)

The main goal of this master's thesis was to study the main principles of classification methods. Basic principles of knowledge discovery process, data mining and using an external class CSSBox are described. Special attantion was paid to implementation of a ,,k-nearest neighbors`` classification method. The first objective of this work was to create training and testing data described by 'n' attributes. The second objective was to perform experimental analysis to determine a good value for 'k', the number of neighbors.

A measure of the quality of Voronoi tessellations resulting from various mesh generators founded on feature-driven models is introduced in this work. A planar tessellation covers an image with polygons of various shapes and sizes. Tessellations have potential utility due to their geometry and the opportunity to derive useful information from them for object recognition, image processing and classification. Problem domains including images are generally feature-endowed, non-random domains. Generators modeled otherwise may easily guarantee quality of meshes but certainly bear no reference to features of the meshed problem domain. They are therefore unsuitable in point pattern identification, characterization and subsequently the study of meshed regions. We therefore found generators on features of the problem domain. This provides a basis for element quality studies and improvement based on quality criteria. The resulting polygonal meshes tessellating an n-dimensional digital image into convex regions are of varying element qualities. Given several types of mesh generating sets, a measure of overall solution quality is introduced to determine their effectiveness. Given a tessellation of general and mixed shapes, this presents a challenge in quality improvement. The Centroidal Voronoi Tessellation (CVT) technique is developed for quality improvement and guarantees of mixed, general-shaped elements and to preserve the validity of the tessellations. Mesh quality indicators and entropies introduced are useful for pattern studies, analysis, recognition and assessing information. Computed features of tessellated spaces are explored for image information content assessment and cell processing to expose detail using information theoretic methods. Tessellated spaces also furnish information on pattern structure and organization through their quality distributions. Mathematical and theoretical results obtained from these spaces help in understanding Voronoi diagrams as well as for their successful applications. Voronoi diagrams expose neighbourhood relations between pattern units. Given this realization, the foundation of near sets is developed for further applications. / February 2017

我國財政制度是否具有公平性往往是財政學者們注意的焦點，國內只單獨探討租稅面之文章非常多，而同時考慮整體財政收支制度文章較少，而且所採用的方法幾乎皆是「有效稅率」、「有效受益率」及「有效淨負擔率」。這些指標主要是判定財政制度是累進抑或累退，其較無法直接判定所得分配改善效果。因此本文最主要是透過租稅及公共支出歸宿假設將各類政府財政收支分攤至每一十分位家庭之所得，求出吉尼係數，利用比較吉尼係數大小來判斷我國財政制度是否會改善所得分配。利用18年資料作分析，以幫助我們更進一步地瞭解我國財政收支對所得重分配影響，所得出的結論和國內一些文章比較。首先在只考慮租稅面情況之下：直接稅具有改善所得分配效果，而間接稅反使所得分配更加惡化，整體賦稅制度具有所得重分配效果，但並非很顯著。其次再單獨考慮支出面情況下：首先對耗源性支出做家庭人口數調整，並將支出對家庭所得影響區分為三組，均顯示我國移轉性支出具有所得分配效果，而耗源性支出會使所得分配惡化，正的移轉性支出效果大於耗源性負效果，所以我國公共支出會使所得分配改善。再者，作整體考量，亦即同時探討租稅面與公共支出面之相互影響，其結果說明財政收支會改善所得重分配，而改善效果最主要來自於支出面而非租稅面。 第一章 緒論 第一節 研究動機與目的 第二節 研究方法與期間 第三節 研究限制 第四節 研究架構 第二章 文獻回顧 第一節 國外文獻 第二節 國內文獻 第三章 理論介紹 第一節 吉尼係數的概念 第二節 Suits Index 第三節 Kienzie Index 第四節 本章小結 第四章 實證程序與估計方法 第一節 預算歸宿之概念 第二節 資料來源限制與處理過程 第三節 所得之定義 第四節 租稅與支出分類 第五節 預算歸宿模型 第五章 實證結果與分析 第一節 賦稅制度對所得分配之影響 第二節 公共支出對所得重分配效果之影響 第三節 財政收支制度對所得重分配之影響 第六章 結論與未來發展
