Esse trabalho teve como objetivo contribuir para o debate sobre a importância das políticas de incentivo à inovação no Brasil. Os resultados esperados do uso que as empresas fizeram dos diferentes tipos de instrumentos sobre os gastos em pesquisa e desenvolvimento (P&D) foram avaliados pelo método de diferenças em diferenças. O método permitiu obter as diferenças de gastos entre empresas beneficiárias de instrumentos e as não-beneficiárias em três períodos consecutivos: 2005 em relação à 2003; 2008 em relação à 2005 e de 2011 em relação à 2008. Ao fazer isso, foi possível identificar se tais diferenças foram positivas e significativas, podendo ser atribuídas às influências dos instrumentos. Os instrumentos utilizados foram: incentivos fiscais, Lei de Informática, financiamentos em parcerias, financiamentos sem parcerias e subvenção. E a utilização dos mesmos pelas empresas teve maior relevância no âmbito de diversos programas de apoio à inovação vigentes no país a partir da retomada das políticas industriais e tecnológicas, nos anos 2000. O estudo concluiu que os efeitos positivos e significativos são limitados à determinados grupos tecnológicos e à poucos instrumentos, em geral, de caráter fiscal. Além disso, esses efeitos positivos surgem em apenas um período, sendo que para cada grupo tecnológico foram efetuadas estimativas para três períodos. Também não houve evidências de que os instrumentos financeiros exerçam efeitos significativos sobre as decisões de gastos em pesquisa e desenvolvimento, apesar da maior ênfase dada aos mesmos no período estudado. Os resultados sugerem fraca influência dos mecanismos de apoio à P&D no Brasil sobre o aumento dos gastos privados, apesar dos avanços recentes. / This study aimed to contribute to the debate about the importance of encouraging innovation policies in Brazil. Understanding the role played by public support instruments to research and development activities in relation to private business spending has become fundamental to achieving this end. The expected results of the use that companies made of different types of instruments on spending were evaluated by the method of difference in differences. This allows you to compare, over a certain period of time, the differences in expenses between the companies that made use of any type of instrument and the companies that did not. Thus, the method yielded differences in spending between the beneficiary and nonbeneficiary firms of those instruments of three consecutive periods: 2005 compared to 2003; 2008 compared to 2005 and 2011 compared to 2008. In doing so, it was possible to identify whether these differences were positive and significant and can be attributed to the influence of the instruments. The instruments used were: tax incentives, Information Technology Law, financing partnerships, financing and grants. And their use by companies had most relevance within various programs to support innovation in force in the country from the resumption of industry and technology policy in the 2000s. The study concluded that the positive and significant effects are limited to certain technological groups and the few instruments in general tax character. In addition, these positive effects arise in one period, and for each technology group estimates were made for three periods. There was also no evidence that the financial instruments carry significant effects on spending decisions on research and development, despite the greater emphasis given to them during the study period. The results suggest weak influence of mechanisms to support R&D in Brazil on the rise in private spending, despite progress in recent years.

隨我國經濟發展與產業結構變遷，從經濟管制到市場自由，自勞力密集之製造出口至技術密集之產業升級，期間有不同階段之稅捐優惠作為引導。 研究發展活動具有外部正面性，同時有市場失靈之可能，私部門可能因此而不願投入、或投入不足之資源，進行研究發展活動。為獲得整體社會之最大利益，稅捐除作為財政工具，作為經濟目的之政策誘因之正當性也獲得承認。政府為促進民間投入研究發展，可能以直接補貼或提供租稅優惠方式給與鼓勵，以協助企業進行研究發展，降低跨足新興產業之進入障礙及營運風險。 但稅捐優惠之提供，乃對具相同負擔稅捐能力者，課以不同之稅捐負擔，以引導特定之作為或不作為，無可避免的違反量能課稅原則下的平等原則。何以相同負擔稅捐能力者，有不同之稅捐負擔，應有實質之說明理由。其成效與影響如何，是否達成制度上犧牲量能課稅原則所欲追求之目的，應與直接補貼接受相同程度之公開之監督與績效衡量。 就研究發展投資支出可抵減之稅額，未分配盈餘加徵百分之十部份乃為縮減營利事業所得稅與個人綜合所得稅之之實現時間差距，而研究發展投資抵減，則為分擔企業研發風險，鼓勵知識之累積，提升附加價值，兩者制定之精神互不相同，以研究發展投資抵減未分配盈餘加徵百分之十之「營利事業所得稅」，似有扞格，但兩稅合一後，營利事業所得稅在公司此一法律主體之稅捐負擔意涵已大幅下降。是以，就研究發展投資抵減未分配盈餘加徵百分之十之稅額部分，衝突程度亦獲得一定程度之解決。另外，所得基本稅額條例規定營利事業及個人皆需有一定之基本稅額負擔，此即所謂最低稅負制。所得基本稅額條例明確將研究發展投資抵減之金額計入營利事業基本稅額之計算，對之課以基本稅額，符合所得基本稅額條例施行之精神，乃合理之設計。 本文以表格方式整理方式，對照獎勵投資條例、促進產業升級條例與產業創新條例對稅基、稅率、稅額與時間歸屬之影響；針對投資抵減實務施行爭議，本研究則整理相關判決以供參考。 以上述三條例之演進趨勢而言，稅捐優惠之給予範圍已逐漸縮小，而改以直接補助或金融協助；技術開發補助與輔導；提供資訊管道、建構交易平台、整合業界、規劃工業區等行政協助，應用多元方式協助產業發展。 研究發展投資抵減之適用範圍、申請期限、申請程序、核定機關、施行期限、抵減率及其他相關實體事項，若立法之技術與資源已有相當累積，以法律位階就投資抵減作較具體之規範，應為立法機關所考慮。 / Abstract With the economic development and the changing in industry structure, from economic regulation to an open market, and from labor-intensive to technology -intensive, the government is guiding the market by tax incentive and other kinds of tool. Because R&D has positive externalities, barriers to entry and the possibilities of market failure, private sector may not willing to input resource for R&D. For social welfare maximization, the government may use tax incentive to encourage private sector to do R&D. By provide R&D Tax Credit or subsidy , the government can encourage the private sector to do more R&D. But providing tax credit will unavoidably conflict with Principle of Ability to Pay. There should be a reason for why people have the same ability to pay the tax pay different tax. The same supervise and performance evaluation must be done for tax credit and subsidy. For 10% surtax on Retained Earnings is to narrow down the time difference between the realized of corporation tax and individual income tax, and the R&D credit is for sharing risk of failure, encouraging research and development, and rising EVA, the tax which can be credited should not include surtax on Retained Earnings. But with the applying of Integrated income tax system, the conflict has been partly solved. For Alternative Minimum Tax, R&D expense can’t be credited is a reasonable design. This paper mainly focus on comparing the differences of tax base, tax rate, and income tax payable etc. in the Enactment of Encouragement Investment, the Statute for Upgrading Industry, and the Statute for Industrial Innovation. Also sued cases were collected to report any violations of existing R&D policies for future amendment concerns. The range of tax credit is shrinking, and is replaced by subsidies, industrial technology development programs, and the setting of science parks etc. And for principle of taxation under the law, The Statute for Industrial Innovation should be ruled in law by the legislative.

The investigation is grounded on a specific concept of contractual networks. In the legal structures of audiovisual production one may observe two distinct levels of contractual connections, one of them more intense and the other one less intense. The level of more intense connections, which corresponds to the contractual arrangements for financing, may be explained by the concept of contractual networks. In the stage of financing the paradox between competition and cooperation displays its largest intensity. We investigate whether there is a normative concept of coproduction as well as which is the anatomy of the coproduction contract. We describe the legislative history of the statutes that introduced the coproduction concept in Brazil. We consider the coproduction contract as cooperative in its nature as opposed to a bilateral arrangement. We identify the following essential elements of the coproduction contract: the separation of obligations for producing the common audiovisual work as well as the sharing of benefits and control on the coproduced work. The copyright on an audiovisual work means a share on the work’s control – the distribution rights – and a split of revenues – the sharing of economic benefits. Audiovisual production results in copyrights of a diverse range of artistic works, which entails distinct economic values with respect to the coproduced audiovisual work itself, and this dynamics has influence on the coproduction contracts. We classify the copyrights according to their economic function and importance to the co-production contracts. Tensions are conflicting situations between coproducers caused by inherent contradictions of the economic networks. We analyze tensions resulting from (i) sharing of control and benefits among co-producers of the co-produced audiovisual works; (ii) liability in case of contractual default as well as recovery of damages; (iii) statutory asymmetries of copyright protection. We examine contractual clauses whose design may either intensify or calm down tensions. In conclusion we provide recommendations for the design of contractual clauses and regulations that can mitigate, control or manage possible tensions in co-production contracts. / Este trabalho investiga o contrato de coprodução audiovisual no contexto de uma rede contratual. O trabalho se baseia num conceito específico de redes contratuais. Na estruturação jurídica da produção audiovisual é possível observar dois níveis distintos de coligação contratual, um mais intenso e outro menos intenso. O nível de coligação contratual mais intenso, que corresponde aos arranjos contratuais para o financiamento à produção, pode ser explicado pelo conceito de redes contratuais. Na etapa de financiamento à produção audiovisual o paradoxo entre competir e cooperar assume a sua maior intensidade. Investigamos se há um conceito normativo de coprodução e o desenho da anatomia do contrato de coprodução. Descrevemos a história legislativa das normas que introduzem a coprodução no Brasil. Consideramos que o contrato de coprodução é um contrato cooperativo e não bilateral. Identificamos como elementos essenciais do contrato de coprodução: a divisão das responsabilidades para a realização da obra comum e o compartilhamento dos benefícios e do controle sobre a obra audiovisual coproduzida. Os direitos autorais sobre uma obra audiovisual resultam na divisão de controle sobre a obra – o exercício dos direitos de distribuição – e na divisão das receitas – o compartilhamento dos resultados econômicos. A produção audiovisual produz direitos autorais sobre obras artísticas variadas, os quais terão valor econômico distinto em relação ao direito autoral sobre a obra audiovisual coproduzida, e essa dinâmica irá se refletir no desenho dos contratos de coprodução. Classificamos esses direitos autorais de acordo com a sua função econômica e importância para os contratos de coprodução. As tensões são situações de conflito entre os coprodutores causadas pelas contradições inerentes aos arranjos econômicos em rede. Analisamos as tensões decorrentes de (i) compartilhamento de controle e benefícios dos coprodutores sobre as obras audiovisuais coproduzidas; (ii) responsabilidade em caso de inadimplemento e reparação de danos; (iii) assimetrias legislativas quanto à proteção de direitos autorais. Examinamos cláusulas contratuais cujo desenho pode agravar as tensões ou mitigá-las. Em conclusão, realizamos recomendações para o desenho de cláusulas contratuais e de regulação que podem mitigar, administrar ou controlar possíveis tensões.

The problem of low domestic savings is inherent in most Southern African Development Community (SADC) countries. This has motivated most of the SADC countries to institute policies that seek to attract foreign capital to cover the investment deficit that arises from low domestic savings rates. This study gives robust conclusions on the effectiveness of individual tax incentives commonly used by SADC countries in attracting foreign mobile capital. This study has broadened the dimensions research can take in analysing the contribution of tax incentives to Foreign Direct Investment (FDI) inflows into developing countries. In separating individual tax incentives mainly used in the SADC region the study gives a robust analysis on the impact of each tax incentive on FDI inflows into SADC countries. The tax incentives used in this study are: tax holidays, corporate income tax (CIT), reduced CIT in specific sectors and losses carried forward. The study also derives data indices for governance, infrastructure and economic policy variables which gives the study clean and reliable data for efficient regression results. These macroeconomic data derivations assist in giving the FDI attraction analysis more variables and well behaved data in drawing conclusions. Through an analysis and comparison of trends in FDI inflows and stock data in different African regions the study draws important conclusions on the impact of the socio-economic environment in FDI attraction. The study, in consultation with data from the period 2004 to 2013 separates the SADC countries into four panels based on resource richness. Panel 1 includes the resources-rich countries, Panel 2 the resources-poor countries, Panel 3 all SADC countries, except South Africa and Panel 4 all the SADC countries. Each of the estimate models in this study, use individual tax incentives variables to avoid the effects of collinearity between different tax incentives variables and to improve the predictive power of the panel data models. This study derived tax incentives data for individual SADC countries, from Ernst and Young’s worldwide tax data. Regular tax incentives in the SADC are derived from tax holidays, corporate income tax (CIT); losses carried forward and reduced CIT in specific sectors. This study seeks to achieve two major objectives: firstly, to establish the effectiveness of tax incentives in attracting FDI inflows into SADC countries, and, secondly, to establish other variables that influence FDI inflows into SADC countries. The study estimated four panels for SADC countries, separated according to resource richness. This was done because different types of FDI are dependent on the available resources in developing countries and thus factors that influence the FDI inflows differ according to resource richness. Resource-seeking FDI moves to resources-rich economies, market-seeking FDI goes to economies that have access to larger markets and efficiency-seeking and strategic-asset-seeking FDI move to economies that ensure efficient use of their capital resources. Thus, as expected, factors that attract FDI to countries in the separate panels differ in direction of causality and magnitude of impact. The study adopts a system Generalised Method of Moments (SYS GMM) methodology to address the problem of endogeneity associated with dynamic panel data models. The estimated results established that tax holidays positively explain FDI inflows in Panel 2. CIT was found to negatively affect FDI inflows into all SADC countries despite their particular category of resource-richness. Losses carried forward are insignificant in all panels and reduced CIT in specific sectors negatively influences FDI inflows in Panel 1 and surprisingly positively influences FDI inflows in Panel 2. The lagged FDI variable shows a positive relationship with current year FDI inflows. The governance index is significant and positively affects FDI inflows in panels 1, 3 and 4. Panel 2 shows a negative relationship between governance and FDI inflows. Market potential measured by GDP growth rate is insignificantly different from zero in all the four panels in the study and negatively signed, except in models A and C of Panel 2. The stock of infrastructure is significant and negatively signed in all the panels. The log natural resources variable though insignificant in some models, mainly, exhibit a significant and negative effect in most models of the study’s panel estimations. The trade openness variable is positively related to FDI inflows in Panel 1. Panel 2 show negative effects of trade openness to FDI inflows. Financial globalisation significantly impacts positive FDI inflows in all the four panels. The economic policy variable is insignificant in all the four panels of the study, except, in model B of Panel 1 where it is weakly significant at 10% level and negatively signed. The study concludes that tax incentives are important in FDI attraction in the SADC countries; therefore, an effective tax mix that ensures efficient use of tax incentives is important to ensure sustainable FDI inflows into the region. Good governance is important in the region for FDI inflows to increase. Increasing government rents from natural resources reduces FDI inflows in the SADC. Previous year flows of FDI are positively related to current year inflows, thus consistent FDI attraction policies in the SADC are important. Infrastructure in the SADC should be consistently improved to ensure suitability with the dynamic nature of foreign investment. Financial markets should be developed to ensure effective flow of capital and growth in economies through more investment. / Economics / D. Com.. (Economics)

À l'intérieur d'un État, la distribution des ressources publiques sur le territoire a une importance fondamentale, parce qu'elle représente un facteur de justice dans les rapports entre collectivités territoriales, de sorte qu’elle conditionne la capacité à assurer les charges liées à l’exercice de leurs compétences, dans le respect de leur autonomie, au profit des habitants qui doivent pouvoir bénéficier d’une qualité minimale des services publics. Cette thèse vise d’abord à étudier et à comparer quelle est l’influence de la forme d’État (unitaire pour la France et fédérative pour le Brésil) sur les mécanismes de la solidarité territoriale. Elle se propose de décrire et d’analyser l’efficacité des mécanismes plus importants (financiers : impôt local, dotations, fonds et transferts facultatifs ; coopératifs : institutions représentatives, politiques publiques nationales, mutualisation et contrats entre collectivités territoriales) mis en place, dès le prélèvement des impôts (nationaux ou locaux), en passant par les incitations fiscales, jusqu’au transfert des ressources aux bénéficiaires. Toute d’abord par une description de l’évolution historique qui explique l’organisation territoriale et la naissance des mécanismes de solidarité actuels, puis en montrant les inégalités importantes qui existent, principalement entre communes pour, enfin, finir avec une analyse prospective de l’efficacité et des défauts (guerre fiscale, corruption et évasion fiscales) de ces mécanismes qui visent à réaliser une péréquation (verticale ou horizontale) des ressources publiques. / Within a state, the distribution of public resources inside the territory have a fundamental importance, because it represents a factor of justice in the relationship between local authorities, so that it affects the ability to provide their obligations related to the exercise of their powers in respect of their autonomy, in benefit of citizens who need to have a minimum quality of public services. This thesis aims first to examine and compare what is the influence of the form of state (Unitary for France and Federal for Brazil) on the mechanisms of territorial solidarity. It aims to describe and analyze the effectiveness of the most important mechanisms (financial: local taxes, grants, funds and discretionary transfers; cooperative: representative institutions, national public policies, pooling and contracts between central state and local authorities). Firstly with a description of the historical evolution of territorial organization and the birth of the current solidarity mechanisms and showing the significant existant inequalities, moreover among municipalities, to finally end up with a prospective analysis of effectiveness and defects (tax war, corruption and tax evasion) of these mechanisms designed to achieve equalization (vertical or horizontal) of public resources.

The Master's thesis "Investment and tax environment of selected former Yugoslavian countries" deals with current tax systems and investment environment of Bosnia and Herzegovina, Croatia and Slovenia. The first three chapters of the thesis are focused on the economic situation of selected countries, their business relations among themselves and the EU countries, foreign direct investment and rating. The fourth key chapter starts with the tax theory and fiscal harmonization within the European Union in order to give detailed analysis of tax systems with emphasis on current development. In conclusion is elaborated the comparison of selected tax systems.

[pt] Esta tese é composta por dois artigos. No primeiro, nós propomos e implementamos um novo índice de vulnerabilidade que é baseado em um VAR bayesiano, estrutural e que pode variar no tempo e junto com um hipótese de exogeneidade em bloco para um determinado par composto por uma economia grande e uma pequena economia aberta. O índice é baseado na soma das respostas da pequena economia aberta a choques na economia grande ao longo do tempo. Isso permite que nós consigamos distinguir e medir as fontes dos choques, varáveis impactadas e duração do co-movimento ou vulnerabilidade. Nosso índice sugere que a vulnerabilidade é determinada principalmente por características específicas de cada par de países, mas tendências mais gerais de descasamento podem ser observadas em um número considerável de pares de países, especialmente em janelas mais longas. Nós propomos uma aplicação desse método a um arcabouço de bancos globais - o que nos permite medir alguns mecanismos teóricos nunca antes medidos. Usando uma amostra de países desenvolvidos e em desenvolvimento, nós não econtramos evidência da prevalência de tais mecanismos sobre co-movimento. No segundo artigo, estudamos como incentivos fiscais impactam o comportamento da firma. Incentivos fiscais tem impacto sobre salários? Incentivos fiscais tem impacto sobre a composição da força de trabalho das firmas? E tem impacto sobre o tamanho dessas firmas? Para responder essas perguntas, combinamos a RAIS com uma nova base de dados - no nível da firma - de dois programas de incentivos fiscais do estado do Espírito Santo - Invest-ES e Compete-ES. Usando o estimador de diferenças em diferenças para efeitos de tratamento intertemporais, nós estumaos os impactos desses programas no nível municipal e, pela primeira vez, no nível das firmas. Nós não encontramos impacto significativo de de incentivos fiscais em quaisquer variáveis de nível municipal. No nível das firmas, por outro lado, nossos resultados indicam que há uma maior migração vinda de outros municípios do estado do Espírito Santo e também indicam que há um crescimento temporário no número de empregos nas firmas tratadas. Com relação a salário e níveis educacionais da força de trabalho, não foi documentado qualquer impacto significativo. / [en] This thesis is composed of two articles. In the first one, we propose and implement a new index of vulnerability which is based on a structural time-varying bayesian VAR with a block-exogeneity hypothesis for a given pair of a large economy and a small open economy. The index is based on the sum of the responses of the small open economy to shocks in the large economy over time, thus allowing us to disentangle and measure the source of the shock, impact variables and duration of the co-movement or vulnerability. Our index suggests that the business cycle co-movement is led primarily by country-pair characteristics, but decoupling trends can be observed in a considerable number of country-pairs, specially at long term windows. We provide an application of this approach to a global banks framework - which allows us to measure some yet unmeasured theoretical mechanisms. Using a sample of developed and developing countries, we find no evidence of the prevalence of such mechanisms in business cycle co-movement. In the second article, we study how tax incentives impact the firm s behavior and choices in the labor market. Do tax incentives affect wages? Do these incentives alter the composition of a firm s labor force? And what about its size? To answer these questions, we merge RAIS - a linked Brazilian employer-employee dataset - with a novel, firm-level, dataset on two fiscal incentives programs in the state of Espírito Santo - Invest-ES and Compete-ES. By using a differences-in-differences estimator of intertemporal treatment effects, we study the impacts of these programs on municipality-level and, for the first time, firm-level variables. We do not find statistically significant impact of fiscal incentives on any relevant municipality-level variables. On firm-level variables, however, our results point to higher migration from other municipalities in the state of Espírito Santo and temporary growth in the number of jobs. Regarding wages and educational levels of the labor force, no statistically significant impact was documented.
