Este trabalho apresenta um novo conceito denominado Impedância Equivalente de Perdas (IEP) que é caracterizado por ser um método prático e econômico que permite calcular perdas técnicas e não técnicas em redes de distribuição de energia elétrica com uma boa precisão, para o qual é utilizado dados que qualquer empresa de distribuição possui, como as contas de energia dos consumidores, os parâmetros elétricos da rede e as medições de potências e correntes na saída da subestação. Para mostrar a aplicação deste método, este documento abrange o processamento dos dados e descrição do software usado para simular a operação de sistemas elétricos testes IEEE 13 e 37 barras, considerando que eles apresentam perdas técnicas e não técnicas. Além disso, estes sistemas são avaliados com diferentes condições de operação, incluindo a incorporação de um gerador fotovoltaico. Os casos avaliados neste trabalho mostram que o método pode ser utilizado para planejar e monitorar as redes de distribuição de energia elétrica considerando a separação de perdas técnicas e não técnicas, para que no futuro as ações de redução dessas perdas possam ser gerenciadas, já que a perda de energia elétrica sem gerenciamento traduz-se em perdas econômicas consideráveis tanto para as concessionárias quanto para os consumidores e indiretamente para o país. Os resultados apresentados nesta dissertação, sobre a aplicação da Impedância Equivalente de Perdas no cálculo das perdas técnicas e não técnicas demonstraram a eficácia do método proposto, vislumbrando-se um grande potencial para a aplicação desse procedimento nas empresas de energia elétrica, principalmente nas distribuidoras de energia.
This work presents a new concept called Loss Equivalent Impedance (LEI), which is characterized by being a practical and economical method that allows calculating technical and non-technical losses in electricity distribution networks with good accuracy, for which it uses the data that any electric utility has, such as the user's electricity bills, the grid's electrical parameters and the measurements of power and currents at the substation coupling point. To show the application of this method, this document covers the data processing and description of the software used to simulate the operation in the test systems IEEE 13 and 37 buses networks, considering that they present technical and non-technical losses. In addition, these systems are evaluated with different operational conditions, including the incorporation of a photovoltaic plant. The cases evaluated in this work show that the method can be used to plan and monitor the electricity distribution networks, considering the separation of technical and non-technical losses, so that in future reduction actions concerning these losses can be managed, since of unmanaged electricity losses is translated into considerable economic losses for both the utility and customers and indirectly for the country. The results presented in this dissertation, regarding the application of the Equivalent Operational Impedance to the calculation of technical and non-technical losses, have demonstrated the effectiveness of the proposed methodology, so that it is foreseen a great potential for the application of the proposed procedure in the electrical sector mainly in the distribution utilities.

Full textFollowing the Linked Open Data principles, data providers have published billions of RDF documents using public SPARQL query services. To ensure these services remains stable and responsive, they enforce quotas on server usage. Queries which exceed these quotas are interrupted and deliver partial results. Such interruption is not an issue if it is possible to resume queries execution afterward. Unfortunately, there is no preemption model for the Web that allows for suspending and resuming SPARQL queries. In this thesis, we propose to tackle the issue of building public SPARQL query servers that allow any data consumer to execute any SPARQL query with complete results. First, we propose a new query execution model called Web Preemption. It allows SPARQL queries to be suspended by the Web server after a fixed time quantum and resumed upon client request. Web preemption is tractable only if its cost in time is negligible compared to the time quantum. Thus, we propose SaGe: a SPARQL query engine that implements Web Preemption with minimal overhead. Experimental results demonstrate that SaGe outperforms existing SPARQL query processing approaches by several orders of magnitude in term of the average total query execution time and the time for first results

Full textThis thesis aims to understand the innovative behavior of French firms, in the context of open and collaborative innovation. Beyond this objective, this study is broadened to include the analysis of the innovation process in Argentinian industrial firms. In view of our results, it turns out that firms have variable needs and capabilities to cooperate (and thus to open their innovation process). Beyond cooperating, firms are interested in different types of partners, which refers to different objectives and contents of cooperation.Our econometric estimations confirm the positive relationship between openness and innovation performance. In addition, our findings suggest that the adoption of open and collaborative innovation practices and the use of formal mechanisms of intellectual property are positively associated.Our analysis of the French competitiveness clusters as an organizational form based on open and collaborative innovation allowed us to understand how the interactions between public and private actors within the "Advancity" competitiveness cluster enable them to mobilize cognitive resources to innovate. In addition, this analysis shows that the participation to competitiveness cluster projects increases R&D intensity of the concerned firms.The comparative study of the innovative behavior of Argentinian and French manufacturing firms highlights that investment in intramural R&D is the main determinant of product and process innovations in both countries. Furthermore, our results underline the difficulties encountered by Argentinian industrial firms to cooperate. Thus, the nature of the partners involved in R&D collaboration is more diversified in France than in Argentina. This illustrates, to a certain extent, the weak development of innovation networks in the latter country and that the dynamics of open and collaborative innovation in Argentina are still limited

Full textReliability of a software, i.e. its capacity to produce the expected behaviour, is essential to the success of software projects. To ensure such reliability, developers need to reduce the amount of bugs in the source code of the software. One of the techniques available to help developers in this task is the use of software metrics, and especially metrics related to the development process.The general objective of this thesis is to contribute to the validation of process metrics, by studying their relationship with software reliability. These metrics, once validated, can be used in bug predictionmodels with the goal to guide maintenance efforts or can be used to create development guidelines. Given the extent of this domain, we chose to focus on one particular aspect of the development process, which is developers organisation, and we studied this organisation in open-source software projects.In parallel to the validation of process metrics, we contributed to the improvement of the methodology used to extract and analyse metrics, thanks to information available in software repositories

Full textIn this thesis the excited-state dynamics of radicals and biradicals were characterized with femto-second pump-probe spectroscopy. These open-shell molecules play important roles as combustion intermediates, in the formation of soot and polycyclic aromatic hydrocarbons, in atmospheric chemistry and in the formation of complex molecules in the interstellar medium and galactic clouds. In these processes molecules frequently occur in some excited state, excited either by thermal energy or radiation. Knowledge of the reactivity and dynamics of these excited states complete our understanding of these complex processes. These highly reactive molecules were produced via pyrolysis from suitable precursors and examined in a molecular beam under collision-free conditions. A first laser now excites the molecule, and a second laser ionizes it. Time-of-flight mass spectrometry allowed a first identification of the molecule, which was completed by the photoelectron spectrum. The photoelectron spectrum was obtained via velocity-map imaging, providing an insight in the electronic states involved. Ion velocity map imaging allowed separation of signal from direct ionization of the radical in the molecular beam and dissociative photoionization of the precursor. During this thesis a modified pBasex algorithm was developed and implemented in python, providing an image inversion tool without interpolation of data points. Especially for noisy photoelectron images this new algorithm delivers better results
In der vorliegenden Dissertation wurde die Dynamik angeregter Zustände von Radikalen und Biradikalen mittels femtosekunden-zeitaufgelöster Anrege-Abfragespektroskopie untersucht. Radikale und Biradikale sind nicht nur wichtige Zwischenprodukte in Verbrennungsprozessen, sondern auch bei der Bildung von Ruß und polyzyklischen aromatischen Kohlenwasserstoffen beteiligt. Des Weiteren spielen sie eine wichtige Rolle in der Atmosphärenchemie und bei der Bildung komplexer Moleküle im interstellaren Medium. Von entscheidender Bedeutung ist in den genannten Prozessen die Anregung der Radikalen und Biradikale in energetisch höhere Zustände, dies geschieht entweder durch thermische Energie oder mittels Strahlung. Für das Verständnis der ablaufenden Vorgänge ist es zwingend erforderlich die Dynamik der angeregten zu verstehen. Die Radikale und Biradikale wurden dafür mittels Pyrolyse eines geeigneten Vorläufers erzeugt, und anschließend unter kollisionsfreien Bedingungen im Molekularstrahl spektroskopisch untersucht. Hierbei regt ein erster Laser das Molekül an, ein zweiter Laser ionisiert es. Mittels Flugzeitmassenspektrometrie wurden die Moleküle identifiziert, und mittels Photoelektronenspektroskopie weiter charackterisiert - unter der Bedingung, dass im Massenspektrum eine Masse dominiert. Das Photoelektronenspektrum wurde mittels Velocity-Map Imaging aufgenommen und gibt einen Einblick in den elektronischen Zustand im Augenblick der Ionisations. Die Velocity-Map Imaging-Technik von Ionen erlaubt außerdem die Unterscheidung von Ionen aus direkter Ionisation und dissoziativer Photoionisation. In diesem Rahmen wurde auch ein modifizierter pBasex-Algorithmus entwickelt und in Python implementiert. Dieser kommt im Gegensatz zum herkömmlichen pBasex-Algorithmus komplett ohne Interpolation der Datenpunkte aus. Besonders bei verrauschten Photoelektronenspektren liefert dieser Algorithmus bessere Ergebnisse

Full textThis research focuses on the field of collaboration between customer and supplier to improve their capability to innovate together. By considering collaboration as a process. It means that its performance could be managed and so improved, under the condition that it could be measurable. To address this issue, we have established a method and created a tool to evaluate the collaboration capability between a customer and its supplier in the context of an innovation project. By using this tool, the partners can obtain a better representation of their collaboration practices and a potential improvement plan adapted to the characteristics of the developed project and the quality of the relationship. The major results of this research include: 1) a qualification of the collaboration process through 18 collective practices, which are evaluated using maturity grids; 2) the proposal of a global indicator called “Potential Collaboration/Co-innovation Index (PCCI)”, which allows to classify the collaboration according to 4 categories: organized, supportive, aligned and fusional; 3) To generate the associated improvement plan. Furthermore, testing our tool on several case studies has enabled us to prove its robustness

Full textDomain Name System (DNS) servers represent key components of Internet networks. Recently, attackers have taken advantage of this service to launch massive Distributed Denial of Service (DDoS) attacks against numerous organizations [1, 2, 3]. This is made possible due to the various vulnerabilities linked to the design, implementation or misconfiguration of the DNS protocol. DNS reflection DDoS attacks are harmful threats for internet users. The goal of this study is to gain a better understanding of DNS reflection DDoS attacks through the investigation of DNS open resolvers around the world. In this context, there is a need for an early phase approach to detect and fingerprint DNS open resolvers. This becomes crucial in the process of investigation. In this thesis, we elaborate on the usage of DNS open resolvers in DNS reflection DDoS attacks. More precisely, the main contribution of our research is as follows : (i) We profile DNS open resolvers, which involves : detecting open resolvers, locating them, fingerprinting their operating system, fingerprinting the type of their connectivity, studying the purpose of their liveness. (ii) We conduct an assessment with respect to DNS open resolvers security and their vulnerabilities. Moreover, we discuss the security features that DNS open resolvers are equipped with, which inadvertently provide the capability to the attackers in order to carry out DNS reflection DDoS attacks. (iii) We present an analysis to demonstrate the association of DNS open resolvers with malware threats.

Full textEl sistema de nombres de dominio (DNS, por sus siglas en inglés, Domain Name System) ha pasado a ser una parte fundamental en la infraestructura de Internet, permitiendo el acceso a los diferentes recursos disponibles de manera fácil y rápida. Este sistema es utilizado para localizar los diferentes sistemas críticos encontrados en internet, permitiendo traducir nombres de dominio memorables en una dirección IP numérica. Dada la gran importancia que este sistema ha obtenido, asegurar su correcto funcionamiento ha pasado a ser un punto fundamental, lo cual ha llevado a implementar sistemas de monitoreo que permitan detectar anormalidades en los servidores DNS. Las herramientas de monitoreo actuales son de carácter privado, o no aprovechan los avances que se han generado para realizar un análisis y alertas más detalladas sobre el estado de estos. Esta memoria describe el análisis, desarrollo e integración de diferentes herramientas open source para realizar el monitoreo de servidores DNS, permitiendo visualizar su estado actual y detectar anormalidades, activando alertas para notificar a los administradores. Además, se busca permitir el análisis de eventos pasados a través del almacenamiento de la información desagregada, permitiendo una visión detallada para el desarrollo de medidas de prevención y mitigación de eventos futuros. La utilización de herramientas open source permite facilitar el acceso al proceso de monitoreo a los administradores de los servidores DNS, y así mejorar la velocidad de reacción ante eventos producidos en esta crítica pieza de internet.

Full textIn almost everything we do, we use the Internet. The Internet is indispensable for our today's lifestyle and to our globalized financial economy. The global Internet traffic is growing exponentially. IXPs are the heart of Internet. They are highly valuable for the Internet as neutral exchange places where all type and size of autonomous systems can "peer" together. The IXPs traffic explode. The 2013 global Internet traffic is equivalent with the largest european IXP today. The fundamental service offer by IXP is a shared layer2 switching fabric. Although it seems a basic functionality, today solutions never address their basic requirements properly. Today networks solutions are inflexible as proprietary closed implementation of a distributed control plane tight together with the data plane. Actual network functions are unmanageable and have no flexibility. We can understand how IXPs operators are desperate reading the EURO-IX "whishlist" of the requirements who need to be implemented in core Ethernet switching equipments. The network vendor solutions for IXPs based on MPLS are imperfect readjustment. SDN is an emerging paradigm decoupling the control and data planes, on opening high performance forwarding plane with OpenFlow. The aims of this thesis is to propose an IXP pragmatic Openflow switching fabric, addressing the critical requirements and bringing more flexibility. Transparency is better for neutrality. IXPs needs a straightforward more transparent layer2 fabric where IXP participants can exchange independently their traffic. Few SDN solutions have been presented already but all of them are proposing fuzzy layer2 and 3 separation. For a better stability not all control planes functions can be decoupled from the data plane. As other goal statement, networking testing tools are essential for qualifying networking equipment. Most of them are software based and enable to perform at high speed with accuracy. Moreover network hardware monitoring and testing being critical for computer networks, current solutions are both extremely expensive and inflexible. The experience in deploying Openflow in production networks has highlight so far significant limitations in the support of the protocol by hardware switches. We presents Umbrella, a new SDN-enabled IXP fabric architecture, that aims at strengthening the separation of control and data plane to increase both robustness, flexibility and reliability of the exchange. Umbrella abolish broadcasting with a pseudo wire and segment routing approach. We demonstrated for an IXP fabric not all the control plane can be decoupled from the date plane. We demonstrate Umbrella can scale and recycle legacy non OpenFlow core switch to reduce migration cost. Into the testing tools lacuna we launch the Open Source Network Tester (OSNT), a fully open-source traffic generator and capture system. Additionally, our approach has demonstrated lower-cost than comparable commercial systems while achieving comparable levels of precision and accuracy; all within an open-source framework extensible with new features to support new applications, while permitting validation and review of the implementation. And we presents the integration of OpenFLow Operations Per Second (OFLOPS), an OpenFlow switch evaluation platform, with the OSNT platform, a hardware-accelerated traffic generation and capturing platform. What is better justification than a real deployment ? We demonstrated the real flexibility and benefit of the Umbrella architecture persuading ten Internet Operators to migrate the entire Toulouse IXP. The hardware testing tools we have developed have been used to qualify the hardware who have been deployed in production. The TouIX is running stable from a year. It is fully managed and monitored through a single web application removing all the legacy complex management systems

Com o desenvolvimento da indústria petrolífera, a exploração do petróleo passou a ser efectuada por um cartel formado pelas empresas multinacionais "chamadas 7 irmãs", que ditavam todas as regras aos países produtores com o objectivo de maximizarem os seus lucros. Desde então, o petróleo tem tido um papel estratégico na economia mundial. O grande interesse do comércio internacional do petróleo, facilitou a adopção de estratégia como um instrumento de política comercial das petrolíferas. A estratégia comercial das empresas petrolíferas bem como da Sonangol, é um conjunto de objectivos estratégicos de exploração, produção, aprovisionamento ou stockagem, transporte, refinação e distribuição de petróleo e produtos petrolíferos, ou seja, um conjunto de objectivos estratégicos desde a prospecção de petróleo até à distribuição ao consumidor final. A estratégia comercial dominante, tem como base, a formação de alianças estratégicas, formação de cartéis e cooperação empresarial entre as petrolíferas.
The drilling of the famous well of Edwin Laurentine Drake in the middle of the XIX century gave birth to the oil industry. With the development of the oil industry, the oil exploitation began to be controlled by a cartel formed by a group of enterprises called "the seven sisters". This group ruled the oil market, imposing their own policies to the producer countries, with the purpose of maximizing their profits. Since then, oil has played a strategical role in the world economy. The importance of oil international trade highlighted strategy as a commercial policy instrument of the oil companies. The commercial strategy of oil companies suchas Sonangol, is a sum of strategic goals in exploitation, production, stocking, transportation, refming and distributing oil and derivatives.

Full textThe need for academic journals and articles changed and increased, amongst other things, due to the successful establishment of online editions. Current attempts to meet the extensive need of the academic reader with bundling journals in packets and interest in consortia, are insufficient. The Open Access (OA) initiative with the concept of free academic publications should have been the solution to the financial limits of the libraries. Given this context the present study identifies if and how German academic libraries consider OA publications in their journal management. One of the key items to answer this research question is the comparative evaluation of a worldwide online survey with 358 library journal managers and 18 representatives of academic publishers. This survey was developed on the basis of a theoretical analysis of the market of academic subscription journals and the (‘zero price’) market of OA publications as well as the structures of journal management and the OA initiative. The key finding of this study are that passivity and uncertainty characterize the handling of OA publications in journal management, especially in Germany. On the other hand university environments in general and particularly in North America and Great Britain are supportive. The gaps in literature supply from readers’ perspective seem not to be big enough to change the established structures interdisciplinary. In addition, it is evident that OA doesn’t save money at all. OA is just switching the access decision from libraries to authors, while the assumption of the financial responsibility stays unclear. OA publications are necessary and useful to satisfy the needs of the academic readers. But for an ongoing consideration in journal management, academic libraries have to analyze the publication culture of the subject disciplines in more detail while at the same time create internal and inter-institutional processes and structures.

Full textWhile much research defend the relevance of the Open Innovation model for both research and practice, we know surprisingly little about the meaning of openness, the various forms it can take and its implementation processes, in particular the two processes known as ‘inside-out’ and ‘coupled’. This dissertation aims to fill these gaps through four essays. It binds researches on patent strategic management with those on the Open Innovation Model and analyzes the practices of licensing viewed as the main mechanism of openness. The essays address the strategic motivations and organizational capacities of licensing in the inside-out and coupled processes. They draw on various theoretical perspectives (ecosystem, coopetition, organizational capacities) and use a qualitative design to individually tackle specific issues derived from the general problematic. The transversal analysis of the results of these essays fills the gaps of existing works and contributes to the literature on Open Innovation model. More precisely, the results clarify the meaning of openness; overtake the dyadic and collaborative view of open innovation; highlight new strategic logics of licensing in the inside-out and coupled processes; and improve the understanding of desorptive capacity by disentangling its microfoundations and origin as well as its articulation with absorptive capacity

Full textWe aim at describing, quantifying and understanding the diversity of situations that explain the low completions observed in MOOCs, based on learning analytics, registration data from the French MOOC platform FUN, course structures, surveys and semi-structured interviews. Most of the attrition is explained by different types of non-starts, and to a lesser extent by voluntary withdrawal: most registrants do not show up in the cours, or do a minimal number of actions, with no intention to engage in the course whatsoever. The existence of an abundant catalog in most platforms drives users to register to more courses than they can follow. Some users view most of the videos of the course without engaging in the tasks required to obtain the certificate, but they represent a small part of the attrition. Academic dismissal is likely to be limited given the fact that most MOOCs are of introductory level, most evaluations are automated and multiple attemps are allowed. Most users follow the course with the intention to apply its content in their personal or professionnal life; a MOOC is most often the equivalent of a learning project. The inability to answer the needs of such learning projects may explain a significant proportion of the voluntary withdrawal. Few learners register in order to obtain a certificate, but most of them are interested in it

Esta dissertação tem como objetivo principal traçar um panorama, a partir do estudo dos aplicativos gerados, sobre como a sociedade brasileira está utilizando Dados Governamentais Abertos. Dados Governamentais Abertos correspondem à disponibilização de dados da esfera governamental em formatos predeterminados (formatos abertos e não proprietários) para a livre utilização, reutilização e redistribuição pela sociedade. A identificação dos aplicativos que utilizam Dados Governamentais Abertos no Brasil é realizada a partir de informações oficiais oriundas do Portal Brasileiro de Dados Abertos e de informações extraídas de notícias sobre Dados Governamentais Abertos no Brasil arquivadas no Observatório de Gestão da Informação a partir do Alerta Google. Desta forma, este estudo pretende desenvolver os seguintes objetivos específicos: identificar e categorizar os temas e os autores dos aplicativos que utilizam Dados Governamentais Abertos no Brasil, assim como os conjuntos de dados utilizados e suas respectivas licenças, e avaliar o grau de atualização dos aplicativos disponibilizados no Portal Brasileiro de Dados Abertos em relação às aplicações identificadas através das notícias sobre Dados Governamentais Abertos arquivadas no Observatório de Gestão da Informação.
This paper aims to give an overview, from the study of the generated applications, about as Brazilian society is using Open Government Data. Open Government Data consist of the provision of data of governmental sphere at predetermined formats (open and non-proprietary standards) for free use, reuse and redistribution by society. The identification of applications that use Open Government Data in Brazil is performed based on official information extracted from the Portal Brasileiro de Dados Abertos and information extracted from news on Open Government Data in Brazil archived on Observatório de Gestão da Informação as from Google Alerts. Thus, this study aims to develop the following specific objectives: identify and categorize the themes and the authors of the applications that use Open Government Data in Brazil, as well as datasets used and their licenses, and assess the degree of update of the applications available in Portal Brasileiro de Dados Abertos relative to applications identified through the news on Open Government Data archived on Observatório de Gestão da Informação.

Full textThe aeronautics industry focuses on decreasing its ecological footprint and increasing airplanes efficiency. One way for this is to design more efficient motors, like CROR, for Counter Rotating Open Rotor. This engine, also called propfan, is quite close to a turbofan, but with a pair of counter rotating propellers instead of ducted fan, which increase its yield. The efficiency is about 30 % higher than a turbofan of equal power, but it generates a lot of noise.This noise has several causes, the main one at low speed (typical takeoff or landing situation), is due to the interaction between propellers. The higher contribution to this interaction is the interaction between rear blades and tip vortexes generated by front blades. The noise generation process of this interaction is complex. It has been shown in previous studies at Onera that vortex kind plays an important role on the generated noise.The goal of this thesis is to identify and classify the influent parameters of this interaction on the noise generation, especially the blade geometry and the vortex properties, and then, to find a silent configuration.To this aim, a parametric study is set up. This study is based on a numerical approach and uses the Cassiopée and Kim computational softwares, developed at Onera. Physical models uses Euler unsteady equations, in their three dimensional and compressible expression, for the CFD and Ffowcs-Williams and Hawkings equations, in their rotating solid surface expression, for the CAA. Simulations are run on high orders schemes and use the Chimera method. Analyses are based on both close field fluid dynamics and far field acoustics.With the results of this parametric study, silent and optimal blades design criteria will be find out.Then, with these criteria, it will be possible to design CROR blades which are aeroacoustically efficient as well as aerodynamically efficient. The outcomes of this thesis are not limited to CROR situation only: any configuration where a blade crosses a vortex orthogonally can benefits from this study, by instance the interaction in a helicopter between the main rotor flow and the tail rotor blades

Resumo: O objetivo desta dissertação é apresentar um modelo para análise de política fiscal em economias abertas, considerando que o choque fiscal desencadeia não apenas um efeito de demanda, mas paralelamente altera as condições de oferta. A partir do artigo seminal "Exchange rate dynamics redux" de Obstfeld & Rogoff (1995) uma extensa literatura que combina rigidez nominal no curto-prazo, imperfeições de mercado, num modelo de equilíbrio geral, desenvolveu-se procurando analisar os impactos de políticas econômicas em economias abertas e seus efeitos spillover. Esta literatura, tradicionalmente conhecido como "New Open Economy Macroeconomics" deu muita importância para análises de política monetária, mas relegou as análises de política fiscal para segundo plano. A despeito disto, estes modelos têm muito potencial para analisar as implicações tanto positivas quanto normativas de política fiscal. Estas análises contemplaram algumas variantes do modelo redux alterando algumas de suas hipóteses e demonstraram grande sensibilidade relacionada às especificações microeconômicas do modelo. Dentre estas, a possibilidade dos gastos públicos gerarem ganhos de produtividade, influenciando a oferta, não foi levada em consideração nesta literatura. Alguns trabalhos de crescimento endógeno e Real Business Cycle, por exemplo, incorporam esta hipótese e apresentaram resultados muito interessantes. O modelo desenvolvido nesta dissertação incorpora esta hipótese seguindo de forma muito próxima o modelo redux, e, permitindo considerar este como um caso particular de nosso modelo. As análises positivas sugerem que os efeitos de choques fiscais descritos no modelo redux têm o mesmo sentido, mas são menos intensas que as variações observadas naquele modelo, por exemplo, para as taxas de câmbio, variação no consumo, efeitos sobre transações correntes, taxas de juros, etc. Este resultado está intimamente relacionado a assunção de que o choque fiscal afeta também as condições de oferta, desencadeando um efeito que se sobrepõe ao choque de demanda do modelo redux. Do ponto de vista normativo, o modelo de Obstfeld & Rogoff (1995) sugere que a política fiscal é beggar-thyself e prosper-thyneighbor. No modelo aqui apresentado, estes efeitos são atenuados na medida em que inserimos algum potencial para os gastos públicos influenciarem a produtividade dos agentes privados. Palavras-chave: "New Open Economy Macroeconomics", Política fiscal, Gasto público produtivo.
Abstract: The main purpose of this dissertation is to present a model to analyze fiscal policy in open economies, considering that the fiscal shock triggers not just an demand effect, but parallel to this effect alters the offer conditions. From Obstfeld & Rogoff (1995) seminal paper "Exchange rate dynamics redux" on, a literature which combines market imperfections, nominal rigidities, in a general equilibrium framework, launched to analyze policies in an open economy setting considering the spillover effects involved. This literature usually known as "New Open Economy Macroeconomics", gave lots of attention to monetary policy, putting aside fiscal policy. Despite of that, these models have a huge potential to analyze the positive and normative implications of fiscal policy. The fiscal policy in the "New Open Economy Macroeconomics" framework studied some changes in the baseline redux model, showing that the results of the models are of great sensibility to the hypothesis considered. Between these, the possibility that public sector expenditures give rise to a improvement in the private productivity was not considered. Some endogenous growth models and Real Business Cycle, for example, incorporate this hypothesis showing interesting results. The model developed in this dissertation incorporate this hypothesis following narrowly the redux model and allowing us to consider that model, in which public expenditure is considered pure waste, a special case of our work. The positive analysis suggest that the effects of fiscal policy described in our model have the same qualitative results as the redux model, but are less sensitive that the results of the original model. This result is linked with the fact that the fiscal shock also changes the supply side of the economy, differently of the redux model. In a normative point of view, Obstfeld & Rogoff (1995) suggest that fiscal policy is beggar-thyself and prosper-the neighbor. In the model that we present here, these effects are attenuated as the public expenditure has the capacity to influence the private productivity. Key-words: "New Open Economy Macroeconomics", Fiscal policy, Productive public expenditure.
