Diplomová práce Ondřej Martínek Abstract Tax havens are thorn in the eye of the OECD countries, nonetheless they emerged originally on europian soil and on the ruins of british empire. Classical accusation argues, the tax havens are supposed to earn on luring foreign capital that is enabled to evade taxation and by that they breach the balance of national budgets and tax justice in developed countries, enwiden social imbalance and speed up global tax competition. There are many forms of tax avoidance via tax havens: transfer pricing, holding structures, trusts, foundations or offshore business. Although many of these forms remain illegal, for certain other ones the states are the ones responsible for - e.g. generous web of double tax treaties. Global shortage to national budgets is estimated at around 3% of total revenues. Tax competition exists and global tax rates are in fact decreasing, however national tax revenues are, in absolute terms, rising. Because of this ambiguous effect on global economy and near impossibility to distinguish "real" tax havens, the developed countries are choosing rather careful policy to the tax havens and concentrate on negotiations and concluding TIEA's.

O mercado pet vem crescendo continuamente, sendo considerado um ramo de atividade em sintonia com a vida moderna. São diversas as mudanças sociais e de comportamento dos tutores de animais de estimação. O aumento de afetividade dessa relação, traz diversos benefícios mutuamente. Os animais de estimação assumem um papel diferenciado e isto se reflete no consumo e principalmente na compra do alimento. Logo, percebe-se o aumento da competitividade, gerada pela atratividade e globalização deste mercado, sendo necessária a implementação práticas modernas de gestão e definição de estratégias. Este trabalho visou analisar e compreender a tributação da ração para cães e gatos e calcular a carga tributária que incide ao consumidor final. As estratégias de gestão tributária são relevantes e influenciam na competitividade empresarial. O STN possui concentração mais elevada na tributação das bases de bens e serviços se comparado a média dos países da OCDE. O governo procura manter sua arrecadação através da política fiscal. Esta pesquisa foi desenvolvida com base em levantamento bibliográfico e documental, sendo uma abordagem qualitativa, descritiva e exploratória. Elaborou-se uma simulação da carga tributária ao longo da cadeia produtiva da ração pet com base na legislação pertinente, obteve-se um percentual de carga tributária na indústria de 52,63%, sobre o distribuidor de 6,61% e sobre o pet shop de 7,30%. Em 2016 a carga tributária média nacional foi de 32,38% do PIB, enquanto que na simulação elaborada obteve-se que o consumidor pagou ao comprar a ração pet, 41,86% de impostos, acumulados ao longo da cadeia produtiva. Notou-se que a tributação da ração pet está 9,48 p.p. maior que a média nacional daquele ano. A tributação da ração vêm sendo apontada constantemente por empresários e entidades do setor como excessiva e um dos principais obstáculos de desenvolvimento. Outrossim, percebe-se que o governo ainda não reconhece os benefícios trazidos por estes animais de estimação para sociedade, visto os aumentos constantes na carga tributária destes produtos. / The pet market has been growing continuously, being considered a branch of activity in tune with modern life. There are several social and behavioral changes of the tutors of these pets. The increased affectivity of this relationship brings several benefits mutually. Pets play a distinct role and this is reflected in consumption and especially in the purchase of food. Therefore, the increase in competitiveness generated by the attractiveness and globalization of this market is evident, and it is necessary to implement modern management practices and define strategic planning. This work aimed to analyze and understand the taxation of ration for dogs and cats and calculate the tax burden on the final consumer. Tax management strategies are relevant and influence business competitiveness. The STN has a higher concentration in the taxation of the bases of goods and services when compared to the average of the OECD countries. The government seeks to maintain its revenue through fiscal policy. This research was developed based on a bibliographical and documentary survey, being a qualitative, descriptive and exploratory approach. A simulation of the tax burden along the pet food production chain was made based on the pertinent legislation, obtaining a percentage of tax burden in the industry of 52.63%, on the distributor of 6.61% and on the pet shop of 7.30%. In 2016 the national average tax burden was 32.38% of GDP, while in the elaborated simulation it was obtained that the consumer paid by buying the pet ration, 41.86% of taxes, accumulated along the productive chain. It was noted that the taxation of pet food is 9.48 pp higher than the national average for that year. The taxation of the ration has been constantly pointed out by businessmen and entities of the sector as excessive and one of the main obstacles of development. Also, it is noticed that the government still does not recognize the benefits brought by these pets to society, given the constant increases in the tax burden of these products.

Title in English: Legal aspects of tax planning in the direct tax area Abstract: In 2012, the European Commission published its Recommendation on aggressive tax planning (2012/772/EU). To counteract aggressive tax planning, Member States should adopt a general anti-abuse rule (GAAR), which is drafted in the Recommendation. At that time, no one knew that GAARs would become obligatory for member states from 2019. In 2013, Organization for Economic Co-operation and Development (OECD) started the BEPS Project, which is considered the biggest revolution in the international tax law system since its creation in the 1950s. I introduce these initiatives and the legal instruments they bring. I focus on GAARs, which I consider to be the most important instruments. Their vagueness allows them to tackle any tax planning scheme. Their importance in the direct tax area grows as they become part of tax treaties based on the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting signed on 7 July 2017 and part of the national legal systems of the EU member states based on the Council Directive (EU) 2016/1164 of 12 July 2016, laying down rules against tax avoidance practices that directly affect the functioning of the internal market. First part of this thesis focuses on...

The footprint firms leave behind on this planet is widely discussed, and the topic of corporate social responsibility is constantly receiving additional attention. The gravity of working towards a more sustainable way of conducting business is illustrated by the incentivized tax system in various countries, where CSR can render tax deductions. It is widely debated if CSR and tax aggressiveness can live in symbiosis, and what relationship the two areas have. However, the literature investigating thisrelationship is scarce, which has left a research gap for the authors of this study to fill.This study does through a quantitative method investigate the relationship between CSR and tax aggressiveness of 3899 firms from 68 different countries, measuredat the end of 2018. By equivalating the level of social responsibility of a firm with the widely accepted ESG-score and the level of tax aggressiveness of a firm with the ETR-index created by the authors, the statistical testing of the relationship was enabled. Further, the control variables country, industry, leverage, beta, and size were included to account for variance in tax aggressiveness which is not captured by the ESG-score.To guide the authors through the establishment of hypothesis and statistical testing,a theoretical framework was established, concluding theories speaking for the implementation of tax aggressiveness, against it, and theories which reconciles the two contradicting views. The data was thereafter processed to investigate which statistical model to utilize. The robust OLS was found to be the best suited model, which was used to test the relationship between the aggregated ESG-score, as well as its components, relationship to the ETR-index.The statistical results in this study did not exhibit a significant relationship between the aggregated ESG-score, nor for the two components S and G, and the ETR-index. There is however a significant positive relationship between the E-score and the ETR-index, showing that environmentally friendly firms are less tax aggressive in general. This relationship could be explained by the stakeholder theory, which indicates that a firm's objective should be to maximize the value creation for all its stakeholders, as well as by the legitimacy theory, stating that firms seek to conduct proper business within socially constructed norms. Furthermore, the results show that tax aggressiveness depends on the country of headcounter, the industry, and the beta of a firm.

O objetivo deste trabalho visou à apresentação de uma abordagem multidisciplinar para a gestão tributária com vistas à maximização do valor da firma em contraponto à abordagem tradicional do planejamento tributário que visa à minimização dos tributos. As estratégias para a minimização dos tributos aumentam o custo em outras dimensões que devem ser analisadas para posicionar a gestão tributária na gestão estratégica da empresa. Para se efetuar a análise da gestão tributária muldisciplinar, propõe-se a utilização do Framework de Scholes e Wolfson, que se baseia em três focos: todas as partes, todos os tributos e todos os custos. Dessa forma é possível não limitar os ângulos de visão, mas sim criar uma sistematização para a gestão tributária multidisciplinar. Como recurso metodológico utilizou-se a pesquisa bibliográfica e análise de casos de estudos que contemplam o uso de instrumentos financeiros derivativos, frequentemente utilizados em planejamentos tributários e que envolvem volumes expressivos de recursos. Restou evidenciado, neste trabalho, que a gestão tributária deve ser realizada de modo integrado na empresa, analisando todos os itens propostos pelo Framework de Scholes e Wolfson, assim, muito mais que minimização de tributos, obtém-se a maximização do valor da empresa / The aim of this paper is to present a multidisciplinary approach for the tax management aiming to maximize the value of the company in relation to the traditional approach of tax planning aiming to minimize taxation. Strategies for minimizing taxes increase the cost in other dimensions, which must be analyzed in order to position the tax management in the company\'s strategic management. In order to conduct the analysis of multidisciplinary tax management, the usage of Scholes and Wolfson\'s Framework is proposed. This framework is based on three focuses: all the parties, all the taxes and all the costs. In this manner, it is possible not to limit the points of view, but to create systematization for the multidisciplinary tax management. As methodological resource, bibliographic research and the analysis of case studies contemplating the usage of derivate financial instruments commonly used in tax planning and which encompass great volume of resources were used. It could be concluded, in this paper, that tax management must be conducted in an integrated manner in the company, analyzing all the items proposed by Scholes and Wolfson\'s Framework. By doing so, it is possible not only to minimize the taxes, but also maximize the company\'s value.

O presente estudo busca analisar a influência do princípio da boa-fé objetiva nos limites do planejamento tributário, mormente no que se refere à possibilidade de desconsideração de atos e negócios jurídicos lícitos realizados pelos contribuintes com o objetivo de minorar a carga tributária. Sobre o tema, parte da doutrina nacional e da jurisprudência administrativa propõe uma releitura da autonomia da vontade, de modo que seriam ilegítimos os planejamentos tributários praticados com abuso do direito, neste compreendido suas diversas espécies, como abuso de formas, falta de propósito negociai, fraude à lei e demais patologias do negócio jurídico. A partir dessa constatação, a boa-fé assume papel de relevo, porquanto serve como elemento conformador da licitude do modo de exercício dos direitos subjetivos e formativos, atuando como verdadeiro fundamento de validade do abuso do direito. Assim, a compreensão dos limites do que pode ser considerado como lícito ou ilícito em matéria de planejamento tributário passa pela definição do conteúdo e da operatividade da boafé no Direito Tributário. Nessa tarefa, no entanto, a doutrina e a jurisprudência, de um modo geral, acabam por realizar uma transposição acrítica do conteúdo da boa-fé objetiva nas relações de Direito Privado, esquecendo-se que o standard de conduta exigido pela boa-fé é influenciado pelas demais normas de um determinado ramo normativo. No caso, as peculiaridades do Direito Tributário, tais como a força com que se liga aos princípios da segurança jurídica e da legalidade e a responsabilidade imposta à Administração Pública decorrente da presunção de legitimidade de seus atos, fazem com que a boa-fé objetiva assuma papel muito mais protetivo do contribuinte. Dessa forma, em que pese a boa-fé objetiva imponha limites ao exercício do direito do contribuinte de planejar suas atividades, esse limite não alcança a possibilidade reconhecer como ilícitos os atos e negócios jurídicos praticados pelos contribuintes no sentido de elidir a norma tributária. / The present study seeks to analyze the influence of the principie of objective good faith in the limits of tax planning, especially in relation to the possibility of disregarding lícít legal acts and business carríed out by taxpayers in order to reduce the tax burden. On the subject, part of the national doctrine and administratíve jurisprudence proposes a rereading of the autonomy of will, so that would be illegitimate the tax planning practiced with abuse of right, in this understood its various species, such as abuse of forms, fraud on the law and other pathologies of the legal business. Based on this observation, good faith plays an important role, since it serves as a constítutíve element of the lawfulness of the way of exercising subjectíve and formatíve rights, actíng as a true basís for the validíty of abuse of right. Thus, the understanding of the limits of what can be considered licit or illícit in tax planning is defíned by the content and operability of good faíth in Tax Law. In this task, however, doctrine and jurisprudence, in a general way, end up performing an uncritical transpositíon of the content of good faith from Prívate Law relatíons, forgetting that the standard of conduct required by good faith ís influenced by the other norms of a certain normatíve area. In this case, the peculíarities of Tax Law, such as the strength with which it is linked to the principies of legal certainty and legality and the responsibility imposed on the Public Administration arisíng from the presumptíon of legitimacy of its acts, make good faith assume a taxpayer's much more protective role. Thus, even though good faith limits the exercise of the ríght of the taxpayer to plan its activities, this limit does not reach the possibility to recognize as illegal the acts and legal business practiced by the taxpayers in the sense of avoidíng the tax rule.

本文包含了两篇关于金融分析师和公司治理的实证研究。第一篇论文（题目为"分析师影响公司避稅吗？来自自然实验的证据"）研究金融分析师对企业避稅的影响。基本回归结果表明追踪公司的分析师越多，公司避稅越少。通过充分利用券商倒闭和券商兼并这两个对金融分析师数量造成的外生冲击，我们利用双重差分的分析方法发现，相比同类公司，经受分析师数量外生下降的公司将从事更多的避稅活动。因此，证据充分表明分析师的数量对企业避稅具有强烈的负面因果影响。我们进一步发现，这一负的因果影响主要集中在本来拥有较少分析师和融资受到约束的公司。此外，在财务信息不透明和企业管制较差的公司，效果也更为明显。综上，该论文提供了新的数据表明，财务信息透明度对于企业避稅具有重要作用。当遭遇外生的分析师下降从而引起信息透明度降低的情况下，公司会更为激进的避稅。 / 第二篇论文（题目为"金融分析师影响公司治理吗？来自自然实验的证据"）利用跟第一篇论文相同的两个自然实验（券商倒闭和券商兼并），进一步探讨了分析师对公司治理的作用。我们发现，当追踪一个公司的金融分析师数量受到这两个自然实验的影响而减少之后，该公司内部现金持有量给股东带来的边际价值减少，其CEO获得更高的超额报酬，其管理层更有可能做出破坏公司价值的收购决策，其管理层更有可能从事盈余管理活动。重要的是，我们发现这些影响主要集中在本来拥有较少分析师和较少市场竞争压力的公司。我们进一步发现，本来拥有较少分析师的这些公司在受到券商倒闭和券商兼并的冲击下，其CEO的报酬和超额报酬对公司业绩较原来更不敏感。这些发现与我们的分析师监督假说是一致的，即金融分析师发挥着审查管理者行为的重要公司治理作用。当公司损失分析师之后，市场在对公司股票定价时会考虑公司因此而产生的代理成本的增加。 / This thesis consists of two empirical studies on financial analysts and corporate governance. The first essay (titled "Does Analyst Coverage Affect Tax Avoidance? Evidence from Natural Experiments") investigates the effects of analyst coverage on corporate tax avoidance. The baseline results indicate that analyst coverage reduces tax avoidance. Using a Difference-in-Differences approach based on two sources of exogenous shocks to analyst coverage - broker closures and mergers, we find that firms engage in more tax avoidance activities after an exogenous drop in the number of analysts following the firm, compared to similar firms that do not experience an exogenous drop in analyst coverage. The evidence therefore suggests a strong negative causal effect of analyst coverage on tax avoidance. We further find that the effects are mainly driven by the firms with smaller initial analyst coverage and more financial constraints. Moreover, the effects are more pronounced in the subset of firms with more information opacity and poorer corporate governance. Overall, the findings suggest that analyst coverage materially and causally affects tax avoidance. Our paper offers novel evidence that information transparency plays an important role in corporate tax avoidance decisions, and with increased information opacity induced by exogenous drops in analyst coverage, firms are likely to avoid tax more aggressively. / The second essay (titled "Do Analysts Matter for Governance? Evidence from Natural Experiments") further explores the causal effects of analyst coverage on mitigating managerial expropriation of outside shareholders, building on the same two natural experiments - broker closures and mergers. We find that as a firm experiences an exogenous decrease in analyst coverage, shareholders value internal cash holdings less, its CEO receives higher excess compensation, its management is more likely to make value-destroying acquisitions, and its managers are more likely to engage in earnings management activities. Importantly, we find that most of these effects are mainly driven by the firms with smaller initial analyst coverage and less product market competition. We further find that after exogenous brokerage terminations, a CEO’s total and excess compensation become less sensitive to firm performance in firms with low initial analyst coverage. These findings are consistent with the monitoring hypothesis, specifically that financial analysts play an important governance role in scrutinizing management behavior, and the market is pricing an increase in expected agency problems after the loss in analyst coverage. / 1.

Ao discorrer-se sobre o tema Planejamento Tributário as considerações remetem, quase que de forma intuitiva, aos interesses unicamente das entidades contribuintes, que depositam nos seus gestores a incumbência de otimização de seus patrimônios. Entretanto, esse é um instrumental igualmente indispensável no repertório de soluções a serem adotadas pelos gestores públicos, também responsáveis em gerir da melhor forma possível o patrimônio, neste caso, da sociedade. Considerando a visão do gestor público sobre Planejamento Tributário, a qual foi chamada Ótica do Estado, este trabalho procurou trazer a dívida ativa nos municípios fluminenses para o centro da discussão, atribuindo-lhe um enfoque mais financeiro, tendo em vista que grande parte dos trabalhos que lhes são direcionados assenta-se sobre considerações jurídico-legais. Sendo assim, foram analisados dados extraídos de órgãos oficiais buscando-se verificar as relações existentes entre a cobrança de créditos inscritos em dívida ativa, os preceitos da Lei de Responsabilidade Fiscal e o comportamento dos contribuintes oriundo da postura do agente fiscalizador. Para tanto, a metodologia foi dividida em duas abordagens distintas (momentos). Para a primeira abordagem foi desenvolvida uma forma de conceituação para os níveis de recebimento de dívida ativa dos municípios, estruturada sobre a adaptação dos critérios desenvolvidos pela Associação Brasileira de Orçamento Público (ABOP); na segunda abordagem foram utilizados também de forma adaptada os parâmetros desenvolvidos pela Secretaria do Tesouro Nacional (STN) para análise das finanças municipais no Brasil. Os resultados sugerem que a maioria dos municípios fluminenses está transgredindo a LRF e que há influência no comportamento fiscal dos contribuintes. / When the issue is the tax planning, the considerations refer, almost automatically, only to the interests of taxpayers, who trust their managers the administration of their patrimonies. Meanwhile, the tax planning is a tool also essential for public administrators, who are responsible for management of the patrimony of the community. Considering the public managers vision about the tax planning, which was called optic of the state, this study aimed to bring the active debt in the municipalities of the state of Rio de Janeiro to the center of the discussion, giving it a more financial focus. We analyzed financial data from official bodies, seeking to verify the relationship between the collection of active debt, the precepts of the Law of Fiscal Responsibility and the taxpayers behavior caused by the position of taxcollector agent. Therefore, the methodology has been divided into two different approaches (moments). In the first moment, was developed a classification form for the receipt levels of active debt in the cities, structured on the adaptation of the criteria established by the Brazilian Association of Public Budget (ABOP). The second moment, were used, also adapted so, the parameters developed by the Secretariat of the National Treasury (STN) for analysis of the municipal finances in Brazil. The results suggest that most of the local authorities are infringing the LRF end that there is influence in the behavior of the taxpayers.
