Um elemento que tem caracterizado países democráticos é a desconfiança institucional. Bancos de dados de pesquisas realizadas em todo o mundo mostram que os cidadãos não têm depositado confiança nas instituições políticas e nos políticos. Para justificar tal comportamento, usualmente são consideradas várias causas como a corrupção, a apatia da própria população e a falha dos governos em propiciar políticas públicas que vão ao encontro das necessidades dos cidadãos. Entretanto, o descrédito na política e nas suas instituições tem base não apenas nessas questões mas também na tributação. Como o impacto do pagamento de impostos no comportamento da população é pouco estudado na América Latina, esta dissertação propôs uma análise sobre a percepção do pagamento tributário e a sua influência na confiança institucional dos porto-alegrenses, com vista a verificar a manutenção do seu Contrato Social. Para averiguar tal questão, foram utilizados dados de pesquisa tipo survey realizada em Porto Alegre/RS, no ano de 2003. A partir desta pesquisa, foi construído um índice de percepção dos impostos para confrontá-lo com dados sobre confiança da população estudada. Os principais resultados alcançados mostraram que os cidadãos porto-alegrenses percebem elementos de manutenção do Contrato Social e têm a sua confiança institucional influenciada pela sua percepção do pagamento tributário / An element that has characterized democratic countries is institutional distrust. Survey research data conducted globally show that the citizens are growingly distrustful of political institutions and politicians. Such behavior is justified based upon corruption, citizen’s apathy and government’s failure in providing public policies design to meet the needs of the citizens. However, the discredit in politics and political institutions are not only explained by those factors but also on how taxes influence the daily life of citizens. As the impact of taxes in the population’s behavior has rarely been studied in Latin America, this dissertation analyzes porto alegrenses’ perceptions about tax payment’s and its influence in their political trust. We basically examine how the relationship between these two dimensions contribute, or not, to the maintenance of the Social Contract. In order to answer this question a survey research was conducted in Porto Alegre/RS, in 2003. An index of perception of tax payment was constructed and then crossed with institutional trust. The results indicate porto-alegrenses demonstrate and support the Social Contract. However, this trust is negatively influenced by the perception of excessive tax payments.

This diploma thesis deals with the economic and legal aspects of excise taxes in the EU. Excise taxes are among indirect taxes and can be divided into three basic groups: alcoholic beverages, tobacco products, and energy products and electricity. For individual commo-dities, EU Member States are harmonizing their legislation and minimum rates in order to prevent cross-border distortions of competition between EU countries. Part of the diploma thesis will be the analysis of the current situation in the field of excise taxes in the EU, the comparison of the individual commodities subject to these taxes.

The objective of the thesis is to investigate the development of excise taxes indicators in twenty-seven member states of the European Union (without Croatia due to the absence of data). The selected period for the analysis is the year 2004 - 2016. The main aim of the thesis is to define the groups of member states EU according to their importance and similarity with respect to the excise duties. With this aim is related the another important idea of the work. That is whether the indicators of excise duties are brought closer to the harmonization processes and if are the member states converging. The cluster analysis was used to achieve the main goal of the work. The data which is used in this analysis is obtained from Eurostat and European Commission databases. The results of cluster analyzes allow the member states to be divided into four of the most stable groups. The group of Nordic countries in Europe, group of border states, states of NMS-12 able to approach the EU-15 and other states of NMS-12. The cluster analyzes also shows that the original and new member states, that joined the EU in 2004 and later, are still different in the field of excise duties. Differences that exist despite the strict harmonization of individual tax systems, in particular the harmonization of excise rates, may be caused, in particular, to the historical roots of individual countries, but also by the economic and political situation.

We extend the dual sourcing model based on the newsvendor framework by considering the environmental impact of transport. In our context, dual sourcing means that a company, e.g. a retailer, uses an offshore and an onshore supplier. We include environmental regulations for transport in the model. Firstly, emission taxes for the transport from the offshore source are considered. It can be shown that with increasing emissions taxes the company sources less from offshore. This improves the environmental performance but the economic performance (expected profit) is severely harmed. Secondly, we propose that an emission trading scheme is valid for transport activities. In this case, the optimal policy turns out to be a two-sided control-limit policy. If the emission limit (expressed in product units) is set to the minimal offshore order quantity the environmental impact of transport can be reduced while the economic performance is nearly not affected. Thus, from managerial perspective emission trading is preferred to an emission tax on transport. Also from the perspective of policy-making emission trading is reasonable as it helps to limit the negative environmental impact of transport but does not strongly reduce the competitiveness of individual companies.

O presente estudo tem como foco central a definição da forma de sindicância das imposições e exonerações tributárias extrafiscais. A relevância do tema se faz sentir em razão do considerável aumento de emprego destas espécies de medidas, sem a respectiva atenção aos seus reflexos no âmbito das garantias e direitos fundamentais. O objetivo último da análise proposta ao longo do estudo é demonstrar que - diferentemente do entendimento predominante em nosso Poder Judiciário - o emprego de instrumentos tributários para a perseguição de finalidades não arrecadatórias ou, ainda, causadores de efeitos preponderantemente não-arrecadatórios não é imune ao controle judicial. Ao contrário, pretende-se esclarecer que os postulados da proporcionalidade e da igualdade servem como critérios para assegurar a compatibilidade entre as finalidades perseguidas ou efeitos causados por estes instrumentos tributários extrafiscais e os demais valores resguardados pelo ordenamento jurídico. Neste sentido, sustentar-se-á que, ao invés de representar um obstáculo absoluto ao exame do mérito das medidas adotadas pelo Poder Legislativo, o sobreprincípio da separação de poderes apenas modifica a extensão e forma de execução do controle judicial. A realização do estudo parte de premissas doutrinárias sobre a extrafiscalidade e do exame do estágio atual de evolução da jurisprudência nacional para definir as causas e conseqüências da ausência de um controle efetivo neste campo do Direito Tributário. Posteriormente, apresenta-se aqueles critérios que deveriam ser empregados para este mesmo controle. / The present paper's central scope is to establish the definition and the form in which the scrutiny of regulatory taxes are imposed and exempted. The relevance of the subject is perceived in light of the considerable increase of the use of these kinds of measures without the respective attention to its reflexes in the realm of fundamental rights and guarantees. The final purpose of the analysis presented throughout this study is to demonstrate that, differently from what is stated in the dominant precedents in our Judiciary, the use of regulatory taxes for non-collection purposes, or even that may cause preponderantly non-collection effects are not immune to judicial control. On the contrary, the object of this paper is to clarify that the principles of proportionality and equality are to be used as criteria to insure the compatibility between the ends pursued and the effects caused by these regulatory taxes and other principles safeguarded by the legal system. In this sense, it is sustained that instead of representing an absolute obstacle to performing the merits exam of the measures taken by the Legislative Power, the separation of powers sobreprincípio only modifies the extension and form of the judicial control that is to be performed. The completion of the study is based upon doctrinarian premises about the regulatory taxes and the exam of the current stage and evolution of the national jurisprudence in defining causes and consequences of the absence of an effective control in this field of Tax Law. Afterwards, the criteria that should be used for this same control are presented.

It seeks to go beyond just claim that much financial resource coming into the coffers of the municipalities from federal transfers would guide its to do that choice and there is other analyzes that could be influencing the decision of the mayors in setting up their tax policies. They are used some municipality geographic variables, political variables, social and demographic variables and even personal managers variables, and financial variables specific to management. The data are drawn from bases provided by the federal government of Brasil as IBGE, FINBRA, DATASUS, SNIS and in a IPEADATA from 2002 to 2013 time window. After analyzing the data, it observed that there are common features between the municipalities and the work previously carried out with countries. In these works, the tax haven nations are mostly small, near financial centers, well managed and with high per capita income (Dharmapala 2006). With municipalities, it appears to be small, metropolitan area, being close to the state capital, have a good Governance and good per capita income the positive influence to have fiscal policy with low rates. The incentives that best fit these characteristics relate to the ISS charges. / Neste estudo, busca-se verificar quais as características que poderiam afetar a decisão de um município em se tornar ou não um paraíso fiscal. Procura-se ir além de apenas alegar que muito recurso financeiro entrando nos cofres dos municípios via transferências federais os levariam a tal escolha e são feitas outras análises que poderiam estar influenciando na decisão dos prefeitos em montar suas políticas fiscais. São utilizadas algumas variáveis geográficas dos munícipios, variáveis políticas, sociais e demográficas e até variáveis pessoais dos gestores, além de variáveis financeiras específicas de gestão. Os dados são retirados de bases fornecidas pelo governo federal do Brasil como IBGE, FINBRA, DATASUS, SNIS E IPEADATA em uma janela de tempo de 2002 a 2013. Após a análise dos dados, foi possível observar que há características comuns entre os municípios que adotam a política de ser um paraíso fiscal e os trabalhos anteriormente realizados estudando países paraísos fiscais. Nesses trabalhos, as nações paraísos fiscais são em sua maioria pequenas, próximas a centros financeiros, são bem geridas e com renda percapita elevada (Dharmapala 2006). Com os municípios, verifica-se que ser pequeno, de região metropolitana, estar próximo à capital do estado, ter uma boa governaça e boa renda percapita os influencia positivamente a ter políticas fiscais com taxas baixas. Os incentivos que mais se ajustam a essas características são relativos às cobranças de ISS.

Cette thèse se compose de trois chapitres qui présentent trois articles indépendants portant sur l’application de modèles dynamiques dans les domaines du marketing et de la finance. Le premier article adopte une approche structurelle des modèles dynamiques pour analyser la relation entre les revenus et l’impact des taxes sur les produits de grignotage (fat taxes). Le deuxième et le troisième article utilisent des modèles dynamiques en forme réduite : nous y mobilisons des modèles hiérarchiques dynamiques qui intègrent un cadre bayésien hiérarchique à un Modèle Linéaire Dynamique. Le second article étudie la tarification dynamique des produits de saison à l’aide d’un modèle hiérarchique dynamique et flexible. Le troisième article analyse le coût du financement des opérations commerciales au cours de la crise financière de 2008-2009 au moyen d’un modèle hiérarchique dynamique. Dans le premier article, nous utilisons un modèle structurel dynamique pour analyser la corrélation entre les revenus et l’impact d’une taxe sur les produits de grignotage (ou fat tax). Les résultats montrent qu’une telle taxe a moins d’impact sur les individus à faibles revenus que sur ceux dont les revenus sont plus élevés, dans la mesure où le premier groupe a davantage tendance à consommer des snacks. Dans le second article, nous élaborons un modèle hiérarchique dynamique et flexible pour estimer la trajectoire des sensibilités-prix afin d’en déduire le tarif dynamique des produits de saison. Nous constatons que les prix optimaux dépendent de la composition de la clientèle du magasin, et que les vendeurs de produits de saisons peuvent en tirer profit lorsqu’ils fixent leurs tarifs. Dans le troisième article, nous utilisons un modèle hiérarchique dynamique pour étudier l’impact de quatre indicateurs macroéconomiques sur le coût du financement des opérations commerciales pendant la crise financière de 2008-2009, ainsi que pendant les périodes qui l’ont précédée et suivie. Nous constatons que l’impact de trois de ces facteurs macroéconomiques (croissance du PIB, échanges commerciaux et inflation) sur le financement commercial est conforme aux prédictions théoriques, tandis que l’impact du quatrième facteur (capitalisation boursière) semble assez surprenant. / This dissertation consists of three chapters that present three standalone essays on the application of dynamic models to marketing and finance. The first essay uses a structural approach to dynamic models to study the role of income on the impact of fat taxes. The second and third essays use a reduced form approach to dynamic models: we use dynamic hierarchical models which incorporate a Hierarchical Bayesian framework in a Dynamic Linear Model. The second essay studies the dynamic pricing of seasonal goods with the help of a flexible dynamic hierarchical model. The third essay studies the cost of trade finance during the financial crisis of 2008-2009 using a dynamic hierarchical model. In the first essay, we use a dynamic structural model to investigate how income interacts with the impact of a “fat tax” (a tax on snack food). We find that the low-income group is less impacted by a “fat tax” compared to the higher income group as they have a higher tendency to consume snack food. In the second essay, we develop a flexible dynamic hierarchical model to estimate the trajectory of price sensitivities which allows us to infer the dynamic prices of seasonal goods. We find that optimal prices depend on the customer composition of the store, and seasonal goods retailers can take advantage of this while setting prices. In the third essay, using a dynamic hierarchical model we examine the impact of four macroeconomic indicators on trade finance costs in and around the financial crisis of 2008-2009. We find the impact of three of these macroeconomic factors (GDP growth, trade and inflation) on trade finance to be in line with the theory, while the impact of the fourth factor (stock market capitalization) on trade finance appears somewhat surprising.

Because financial accounting rules afford managers more flexibility and discretion in reporting than tax accounting rules, prior studies suggest that large differences between book and taxable income indicate lower quality (or less persistent) earnings. Lev and Nissim and Hanlon provide evidence that BTDs contain information about future firm performance, but the nature of the causality in this relation is not clear. While BTDs could proxy for earnings quality, they may also reveal underlying economic events or management's private information about future performance or simply predict future reversals in effective tax rates. I divide total BTDs into their measurable components: temporary (deferred taxes) and non-temporary (permanent differences and tax accruals), and test their relation with the components of net income changes: pretax earnings changes and tax expense changes. I hypothesize that the non-temporary component of BTDs is negatively related to future changes in tax expense, whereas the temporary component of BTDs is negatively related to changes in future pretax earnings. I also examine the maintained hypothesis that the lower earnings growth for large BTD firms is due to earnings management. I use various proxies from prior literature to identify firms potentially managing earnings and test whether the presence or absence of suspected earnings management activity alters the relation between BTDs and earnings changes. My results provide compelling evidence that permanent BTDs are related only to future changes in tax expense, and temporary BTDs are related to changes in pretax earnings. These results are robust to multiple sensitivity analyses, including a replication of the sample and methodology of Lev and Nissim. The results also hold in the case of firms not suspected of earnings management. In fact, 1 find only limited evidence that the results are stronger in the presence of earnings management. Overall, my study suggests that it is only the temporary component of BTDs that is related to future firm performance, with non-temporary differences being related to future tax expense changes, and that these results are primarily due to underlying economic factors, not earnings management. / Committee in charge: David Guenther, Chairperson, Accounting; Steven Matsunaga, Member, Accounting; Linda Krull, Member, Accounting; Glen Waddell, Outside Member, Economics

xv, 147 p. : ill. (some col.) / This thesis examines the Special Assessment of Historic Property Program, a property tax incentive available to owners of historic properties in the U.S. State of Oregon. While several studies and task force reports have been prepared since the Program was signed into law in 1975, none have included the thorough chronological context that this thesis intends to provide. Additionally, with the numerous changes to the Special Assessment Program since the early 1990s, this thesis aims to provide a current evaluation of the incentive provided to participating property owners and governments to preserve significant historic resources. Documents, case studies, and interviews were used to provide a better understanding of a program that has come under repeated criticisms in years past. This thesis will provide a baseline for future research and criticism--both positive and negative--of the Special Assessment Program, a hallmark of the historic preservation movement in Oregon. / Committee in charge: Dr. Michael Hibbard, Chairperson; Eric Eisemann, Member; Jessica Engeman, Member

Esta pesquisa busca analisar a influência da tributação e da governança corporativa sobre as políticas de dividendos das companhias de capital aberto brasileiras no período de 1986 a 2011, através de estimações Probit e Tobit com dados em painel. Particularmente no Brasil houve diversas mudanças na legislação tributária dentro do período analisado, sendo assim uma boa oportunidade para esse estudo. Os resultados empíricos sugerem que: a) quando houve aumento no Lucro Por Ação, o percentual do lucro distribuído em forma de proventos foi maior nos períodos em que não houve incidência de tributação e menor quando houve incidência de tributação; b) companhias estatais distribuíram menos dividendos do que companhias privadas; c) companhias que distribuíram dividendos também distribuíram Juros Sobre Capital Próprio; d) companhias que possuem governança corporativa tendem a distribuir mais dividendos. / This paper investigates the influence of taxes and corporate governance on dividend policy of Brazilian public companies in the years 1986 to 2011, using panel data Probit and Tobit estimation. There are several tax law changes particularly in Brazil within the period analyzed, creating a good opportunity to study dividend policy. Empirical results suggests that (a) when Earnings Per Share increased, the percentage of profits distributed in the form of dividends was higher in periods in which there was no incidence of taxation and lower when there was incidence of taxation; (b) state owned companies paid less dividends than private companies; (c) companies that paid dividends also paid Interest On Equity Capital; (d) companies under corporate governance best practices tend to pay more dividends.
