O presente trabalho tem como principal objetivo mostrar de forma empírica a importância relativa do setor agrícola na estrutura produtiva do estado do Mato Grosso, o qual tem apresentado um excepcional desempenho da atividade agrícola no contexto atual. Para tanto, utiliza-se de um modelo insumo-produto inter-regional construído para duas regiões, a saber, Mato Grosso e resto do Brasil, referente ao ano de 1999. A partir dos indicadores desta metodologia, procura-se identificar os setores mais importantes das economias em questão, seus encadeamentos e a propagação de impactos entre as regiões. Além disso, o trabalho faz ainda uma aplicação do modelo para verificar qual o impacto das exportações mato-grossenses, em especial da soja, sobre a produção total, valor adicionado e número de empregos gerados na economia, bem como calcula o PIB do agronegócio da soja no Mato Grosso, além de verificar qual o impacto causado na produção dos transportes rodoviário e ferroviário, nas duas regiões, ao atender a demanda final de cada atividade pertencente ao estado do Mato Grosso. Pelos resultados obtidos, pode-se confirmar a hipótese formulada a respeito da importância dos setores primários para a economia do estado. De acordo com os índices puros de ligações, verificou-se que os setores agrícolas como Soja, Bovinos e Outros da pecuária, foram considerados como chave ou pólos de desenvolvimento econômico na região em estudo, em função de suas fortes relações de compra e venda de insumos na economia. Além destes, quatro setores diretamente relacionados à agropecuária foram também identificados como chave, a saber: Fabricação de óleos vegetais, Abate de bovinos, Abate de outros animais e Álcool. Em especial merece destaque a cultura da soja no Mato Grosso, que embora tenha uma baixa geração direta de emprego e renda, apresenta um elevado efeito multiplicador destas variáveis na economia, uma característica intrínseca de setores altamente produtivos e intensivos em capital, além de destacar-se também como pólo de desenvolvimento econômico em função de suas fortes ligações, conforme mencionado no parágrafo anterior. As evidências empíricas confirmaram também a importância do setor em termos de suas exportações, as quais causam importante impacto na produção e geração de empregos em diversos outros setores, além de atrair ganhos cambiais ao país. Finalmente, o trabalho desenvolve um ferramental útil para a formulação de políticas públicas para o estado do Mato Grosso, embora sejam necessárias algumas atualizações e refinamentos da metodologia utilizada, para que se possa desenvolver um instrumental de avaliação de políticas de estímulo ao desenvolvimento da infra-estrutura de transportes da região, uma vez que esta última constitui-se peça fundamental ao crescimento econômico. / The main goal of this study is to show the empiric frame of the relative importance of agricultural sector into the productive framework of the Mato Grosso State, which has shown an exceptional agricultural activities growth in the actual context. For this purposes, it becomes useful to adopt an inter-regional input-output model built for two regions: Mato Grosso State and rest of Brazil, regarding to 1999. From the indicators of this methodology, it looks for finding the more important sectors of those economies, and its linkages and impacts between the regions as well. Moreover, this study even encourages to make some simulations to verify how the Mato Grosso’s exportations impacts on the total product, income and employment, specially those ones originated from soybean. It was possible to calculate the Mato Grosso’s soybean agribusiness GDP (Gross Domestic Product), besides verifying how much impacts were generated on highways and railways transports. According to results obtained, it is possible to confirm the created hypotheses regarding importance of primary sectors for the state economy. According to pure linkages indexes, it was checked that some sectors such soybean production, beef cattle production and other ones were considered like key sectors or economic developed pools for the region studied. In addition of those ones, four other sectors directly linked with agriculture were also found out like key sectors, so they are vegetable oils production, beef cattle and other slaughters, and alcohol production. The soybean crops is really a spot in Mato Grosso State, even though it has a low generation of directs income and employment. As a matter of fact, the soybean crops have a high multiplier effect on these economy variables, an own feature of highly productive and capital intensive sectors, and it is a prominence sector like a developing economic pool, as seen before. The empiric evidences confirmed the importance of sector in terms of its exportations too, which strongly impacts on product and employments generation in other ones sectors, besides attracting exchanges gains to the country. Finally, this input-output analysis creates an important tool to the public policy formulations of Mato Grosso State, although its important to make some updates and fits on the methodology applied to be able developing a whole evaluation instrumental kit of entire stimulant policies that might develop for example an efficient regional transport structure, due to this one consists of an essential device to the economic growth.

An increasing number of countries develop bio-economy strategies to promote a stronger reliance on the efficient use of renewable biological resources in order to meet multiple sustainability challenges. At the global scale, however, bio-economies are diverse, with sectors such as agriculture, forestry, energy, chemicals, pharmaceuticals, as well as science and education. In this study, we developed a typology of bio-economies based on country-specific characteristics, and describe five different bio-economy types with varying degrees of importance in the primary and the high-tech sector. We also matched the bio-economy types against the foci of their bio-economy strategies and evaluated their sustainability performance. Overall, high-tech bio-economies seem to be more diversified in terms of their policy strategies while the policies of those relying on the primary sector are focused on bioenergy and high-tech industries. In terms of sustainability performance, indicators suggest that diversified high-tech economies have experienced a slight sustainability improvement, especially in terms of resource consumption. Footprints remain, however, at the highest levels compared to all other bio-economy types with large amounts of resources and raw materials being imported from other countries. These results highlight the necessity of developed high-tech bio-economies to further decrease their environmental footprint domestically and internationally, and the importance of biotechnology innovation transfer after critical and comprehensive sustainability assessments.

Text in Afrikaans / Summaries in English and Afrikaans / The orthodox school's explanation for wage differentials, unemployment and labour market discrimination and the policy measures which they proposed did not offer workable solutions to the problems of the day. During the late 1960s and early 1970s a group of American labour economists conducted field studies in American urban ghettos which resulted in the formulation of the dual labour market theory. In contrast with the orthodox approach, which emphasises free market forces and investment in human capital, the dual labour market theory focuses on the dual structure of the labour market. The labour market is divided between a primary (high-wage) and a secondary (low-wage) sector, with little or no mobility between the sectors. An oversupply of labour in the secondary sector and unemployment are the results. These labour market phenomena and dualism also characterise the South African labour market and should be taken into account when policy measures are formulated. / Loonverskille, werkloosheid en arbeidsmarkdiskriminasie is algemene verskynsels in arbeids· markte wereldwyd.

A Rodada Doha foi a primeira rodada de negociações da OMC, que iniciou em 2001 e se estende até os dias atuais. Inúmeros impasses no contexto multilateral afloraram das mesas de negociação na OMC, principalmente na área agrícola, de especial interesse para o Brasil. Sendo assim, o objetivo da dissertação é simular reduções de barreiras tarifárias e não tarifárias, no âmbito multilateral, e verificar quais seriam os benefícios para o Brasil, com ênfase sobre o setor primário. Para tanto, foi estimado um modelo de equilíbrio geral computável, por meio do software GTAP, e quatro cenários que incorporaram reduções de barreiras tarifárias e não tarifárias foram realizados. Os resultados mostram que, especificamente para o Brasil, nos cenários em que só são incorporadas reduções de tarifas, o setor primário e de agroindústria seriam os mais beneficiados. Já a redução multilateral das BNTs favoreceria, especialmente, os setores industriais, de maior conteúdo tecnológico. Quando simulados ambos, reduções de BNT combinados com reduções tarifárias, todos os setores aumentariam as exportações, principalmente a pecuária, agroindústria e manufaturas de alta intensidade tecnológica. Em relação ao bem-estar, os cenários que incorporam redução de BNTs ou reduções combinadas de BNTs e tarifas são os mais benéficos para todas as regiões incluídas no estudo, com ganhos mundiais que podem alcançar mais de US$ 1 trilhão. / The World Trade Organization (WTO) officially commenced on January 1, 1995, for the purpose of administering the multilateral trading system. Doha Round was the first round of WTO negotiations, which began in 2001 and extends to the present day. Numerous impasses in the multilateral context have emerged from the negotiating tables in the WTO, especially in the agricultural area, of special interest to Brazil. Thus, the objective of the dissertation is to simulate reductions in tariff and non-tariff barriers at the multilateral level, and to verify the benefits to Brazil, with emphasis on the primary sector. For that, a computable general equilibrium model was estimated using the GTAP software, and four scenarios that incorporated reductions of tariff and non-tariff barriers were performed. The results show that, specifically for Brazil, in the scenarios in which only tariff reductions are incorporated, the primary and agroindustry sectors would be the most benefited. The multilateral reduction of BNTs would favor, especially, the industrial sectors, with greater technological content. When both, BNT reductions combined with tariff reductions were simulated, all sectors would increase exports, especially livestock, agro-industry, and high-tech manufactures. Concerning well-being, scenarios incorporating reductions in BNTs or combined reductions in BNTs and tariffs are the most beneficial for all regions included in the study, with global gains that can reach over $ 1 trillion.

Le droit des sûretés réelles a fait l’objet de profondes mutations à la suite de plusieurs réformes successives qui viennent de l’affecter. Si la matière s’est indubitablement modernisée, il reste qu’elle souffre d’un manque de cohérence globale qui tient tout à la fois à la trop grande offre de sûretés et à l’insuffisance de règles fédératrices venant régir l’ensemble. La question se pose alors de savoir s’il est possible et envisageable de dégager un socle de règles communes plus élaboré, voire même un droit commun, et selon quelles modalités. Il en ressort l’interrogation sur l’efficacité du droit ohada des sûretés réelles au regard de l’inadéquation entre les objectifs du législateur africain et les moyens qu’il a mis en oeuvre pour les atteindre. Au regard des expériences internationales, la réponse à ces questionnements réside à notre sens dans une réforme plus ambitieuse du droit ohada des sûretés réelles qui se traduirait par l’adoption d’une approche fonctionnelle telle qu’il nous a été donné de voir dans des pays appartenant à la même tradition juridique que la nôtre. Plus concrètement, il s’agira de redonner, à travers cette conception fonctionnelle des sûretés, de la cohérence, de la simplicité et de l’accessibilité, en somme de l’efficacité au droit ohada des sûretés réelles de manière à le rapprocher des populations et des réalités socio-économiques des États de l’ohada tout en n’occultant pas les enjeux économiques internationaux. / The real security interests law/secured transactions has gone through crucial changes following a series of several reforms which has affected it. If the subject matter has undoubtedly been modernized, it is obvious that the real security interests law/secured transactions is still lacking of general consistency which is linked simultaneously to the large numbers of proposal on security interests and to the insufficiency of federative rules which come to govern the whole. Actually, the problem poses the question to know if it is possible and conceivable to put forward a base of more sophisticated general rules, or even a general law, and according to what methods? The interrogation underlines the efficacy of ohada real securities law in regard to the inadequacy between the objectives of the African legislator and the means used by him to achieve them. In other words, it is admitted to question on the way of a reinforcement of the actual real securities law in sight of a greatest efficacy. In regard to the international experiences, the answer of these questioning is found, in our opinion, in a reform more ambitious of the ohada real securities law which is going to lead to the adoption of a functional approach as it was observed in States with the same juridical culture of ours. In concrete terms, it is important to give back, through this functional conception of securities interest, coherence, and simplicity, in sum, efficacy to ohada real securities law likewise to bring it closer to the population and to the socio-economic realities of ohada member States while revealing the international economic stakes.
