O objetivo principal deste trabalho é identificar quais são os possíveis impactos que a adoção de um novo modelo de contratação de empreendimentos populares pela Caixa Econômica Federal (CAIXA) tem sobre a promoção da inovação e da sustentabilidade na cadeia brasileira da construção civil. Apesar de possuir diversas definições, o conceito mais aceito de sustentabilidade é a capacidade de atender as necessidades do presente sem impedir que as futuras gerações satisfaçam suas necessidades. O movimento em prol da sustentabilidade vem se fortalecendo rapidamente no mundo no início deste século XXI, instigando a sociedade civil a repensar seu comportamento de consumo, impactando diretamente sobre o comportamento de produção das empresas. Neste processo de mudança, a capacidade de inovar, isto é, de produzir novos conhecimentos ou aplicar de maneira diferentes conhecimentos existentes, é estratégica para que as empresas possam se adaptar a este novo contexto em que a sustentabilidade é requisito de participação no mercado. Um modelo de compra estratégica de empreendimentos populares baseado em desempenho, ao modificar a metodologia de seleção, contratação e acompanhamento das construtoras se apresenta como uma maneira do Estado influenciar o setor brasileiro da construção civil em direção à sustentabilidade. Através de uma pesquisa exploratória teórica, apresentamos uma forma de aplicação do modelo de compra estratégica baseada em desempenho desenvolvida nos Estados Unidos no início dos anos 1990 e identificamos seu potencial em estimular a sustentabilidade, devido principalmente à maneira como são descritas as características dos empreendimentos a serem construídos, e a inovação, devido à maneira como se dá a relação entre proponentes e a CAIXA durante o processo de seleção dos empreendimentos. A principal conclusão desta pesquisa é que o modelo apresentado tem um potencial muito maior que o atual em promover a inovação e a sustentabilidade no setor brasileiro da construção civil, uma vez que apresenta novos papéis e uma nova dinâmica de relacionamento entre todos os agentes envolvidos na implantação da política pública de habitação. / The main purpose of this research is to identify the possible impacts the adoption of a new purchasing model of popular buildings by Caixa Econômica Federal (CAIXA) has on the promotion of innovation and sustainability in the Brazilian building chain. Despite several definitions, the most accepted concept of sustainable development is the development which meets the needs of the present without compromising the ability of future generations to meet their own needs. The sustainability movement is quickly getting stronger in the beginning of the 21st century, urging civil society to rethink its consumption pattern. This has a direct impact over companies production pattern. On this change process, the ability to innovate, that is, to develop new knowledge or apply in different matters the existing knowledge, is strategic to companies adapt to this new context where sustainability is a condition to keep in market. A performance-based procurement model of popular housing, once it modifies the methodology of selection, award and monitoring building companies, becomes a way to the State promote the Brazilian building sector towards sustainability. Through a theoretical exploratory research, we present a model of performance-based procurement developed in the USA in the 1990´s and we identify its potential to promote sustainability and innovation, mainly due to the way the request for proposal is done. The main finding of this research is that the presented model has a greater potential than the actual one to foster innovation and sustainability in the Brazilian building sector, once it presents new roles and a new relationship dynamics among all agents involved in the implementation of the public housing policy.

Le discours publicitaire d’aujourd’hui ne se limite plus seulement à une description technique des produits, mais participe aussi à la construction de systèmes de valeurs selon une logique de calage qui consiste à se mettre au diapason des courants sociaux et des aspirations des individus. L’apparition de comportements de consommation inédits oblige les marques à renouveler leurs stratégies de communication, quitte à faire évoluer le rôle social de la publicité. Au milieu des années quatre-vingt, la marque Benetton s’illustre en proposant une vision politique de la consommation soutenue par un discours publicitaire qui ne vante plus les qualités du produit ni ne fait appel à la dimension hédonique de la consommation. Au contraire, il se réfère à des événements d’actualité traités ordinairement par le discours médiatique et s’adresse à des citoyens-consommateurs. D’autres acteurs économiques s’inscrivent depuis dans cette tendance. À partir d’une analyse sémiotique des publicités de l’enseigne E. Leclerc, l’objectif de cette recherche est de mettre en évidence l’existence d’un discours publicitaire particulier qui n’est plus conventionnel à partir du moment où il convoque une dimension politique. Affichant une posture militante sur la question écologique ou celle du pouvoir d’achat, l’enseigne transgresse les codes du discours publicitaire pour revendiquer un engagement citoyen. Les résultats d’analyse montrent par ailleurs que l’installation d’un champ discursif relativement éloigné de la fonction commerciale de l’enseigne témoigne de l’évolution de la société postmoderne à laisser la gestion de l’intérêt général aux entreprises privées, au détriment de l’action publique. / Advertising discourse today is no longer limited to only a technical description of products, but also participates in the construction of values. In that way it is attuned to social currents and aspirations of individuals. The emergence of new consumer behaviors requires brands to renew their communication strategies, even to change the social role of advertising. In the mid-eighties, the Benetton brand proposed a political vision of consumption supported by advertising discourse that no longer boasts the qualities of the product or does not use the hedonic dimension of consumption. Rather, it refers to current events usually treated by the media discourse, and is intended for citizens and consumers. Since then other economic actors follow this approach. From a semiotic analysis of advertisements of E. Leclerc, the objective of this research is to demonstrate the existence of a particular advertising discourse which is no longer conventional since it carries a political dimension. Featuring a militant stance on ecological matters or purchasing power, the brand transgresses the codes of advertising discourse to claim a civic engagement. The analysis results also show that the emergence of a field which is relatively distant from the commercial function of the brand reflects the evolution of postmodern society to leave the management of the general interest to private companies, to detriment of public action.

<p>In Sweden according to the planning and building Act municipalities have planning monopoly. The question about shopping centres in the outskirts of cities is a regional issue, because they attract customers from a large area. Municipalities often find it hard to assert themselves against large commercial companies when it comes to their establishing new retail outlets on the outskirts of cities. Without a regional co-operation there is a risk that municipalities can be played up against one another, so that more and more companies are given permits without the municipalities having taken the strategic consideration necessary for a long term sustainable development. The focus in this work is on four municipalities in the Södertörn region (Södertälje, Botkyrka, Huddinge and Nynäshamn). Today there are some out-of-town retail outlets in the first three municipalities. The main aim of this thesis is to explain why there is no co-operation between municipalities in Södertörn concerning out-of-town retailing. The aim is also to connect sustainable city development with the problems of out-of-town retails as well as the municipalities commercial policy. The study uses a hermeneutic approach and a qualitative method with one case-study. The interviews are partly based on standard procedures.</p><p>Out-of-town retail outlets entail private car use and this is a problem from a city development perspective. To reach a sustainable city development it is important to expand transport options such as walking, biking and public transport. The project Sustainable Travel (Hållbart resande) at Södertörn supports this development. Some of the municipalities in Södertörn are trying to revitalise their local centres and this is positive from a social and ecological perspective. The four municipalities however do not co-operate concerning out-of-town retailing, and this reverts the issue back to a lack of regional planning, and their competing for purchasing power.</p>

Besides putting it in a context of innovation in the public sector, the study of this issue must consider all its variables and questions, whwther of legal, economic, social or political order, starting with the one I consider the most important: the possibility of the State to assert its power of puchasing in order to design and promote markets, searching to achieve other objectives rather than those traditionally accepted. Thus, in the analysis of a direct application of a new practice, this study evaluates the implementation of the Additional Law number 123/06, which gives a differentiating treatment to micro and small enterprises in public contracting. By means of interviews, information was collected with the relevant actors in in this phase. The conclusion was that aspects such as the heterogeneity of the segment of the MPE`s and their low capacity of articulation, along with the endogenous obstacles of the instituion of the bidding, contribute decively to the low stage of the implementation that occurs at this moment. / Esta dissertação busca resgatar o debate sobre a utilização do Uso do poder de compra do Estado como um instrumento para dinamizar outras políticas públicas estabelecidas pelos entes federativos. Além de colocá-lo dentro de um contexto de inovação no setor público, o estudo deste tema deve ser feito considerando-se todas as suas variáveis e questionamentos, sejam eles de ordem legal, econômica, social ou política, a começar por aquele que considero o principal, que é o que se refere sobre a possibilidade de o Estado se valer do seu poder de compra para desenhar e fomentar mercados, com vistas a alcançar outros objetivos que não aqueles tradicionalmente aceitos. Assim, na análise de uma aplicação direta desta nova prática, este estudo avalia a implementação da Lei Complementar n.° 123/06, que passa a conceber um tratamento diferenciado para as micro e pequenas empresas nas contratações públicas. Por meio de entrevistas foram coletadas informações com os atores relevantes para esta fase, concluindo-se que aspectos como a heterogeneidade do segmento das MPE`s e sua baixa capacidade de articulação, juntamente com as ações pouco articuladas executadas pelos órgãos envolvidos quando associadas aos óbices endógenos do instituto da licitação, contribuem de forma decisiva para baixo estágio da implementação que se verifica neste momento.

Obtaining empirical evidence to support the validity of PPP, however, has traditionally been a controversial issue. Nevertheless, a consensus slowly appears to be emerging from literature, suggesting that PPP holds, but only in the long run. Although PPP is not useful to predict the behavior of the exchange-rate in a time frame that would make it a useful application in the context of the foreign exchange market, it is widely used in applied macroeconomics, often as a long-term restriction for the behavior of the exchange-rate in general equilibrium models. In any case, as Dornbush and Krugman remind us, “Under the skin of any international economist lies a deep-seated belief in some variant of the PPP theory of the exchange rate”. This dissertation proposes to assess the evidence for PPP in more than a century of data for the largest Latin American economies. In the empirical literature, most of the empirical work testing the validity of PPP in the long run uses data from the developed countries (in part, simply because they are more readily available). Taylor (2002) includes Argentina, Brazil and Mexico in his sample of 20 developed and developing nations. Other studies focus specifically on the data of one or the other economy in Latin America (for example, Délano 1998 tests the PPP hypothesis using data from Chile between 1835 and 1995). But there has been little work done on this field focusing specifically on data from Latin America. Following the usual methodology described in literature – unit root tests to assess whether the real exchange rate is stationary, applying error correction mechanisms and cointegration tests – the evidence obtained from Latin American data reinforces the thesis that PPP holds in the long run. / A teoria da paridade do poder de compra (PPP) foi formalizada há quase um século por Gustav Cassel como um paradigma para explicar o comportamento das taxas de câmbio. Sua comprovação empírica é historicamente controversa, mas aos poucos, a literatura parece convergir para o consenso de que a PPP é válida, mas apenas no longo prazo. Ainda que a PPP não sirva para prever o comportamento da taxa de câmbio no curto prazo, seu uso é disseminado na macroeconomia aplicada como restrição de longo prazo para a taxa de câmbio. Como lembram Dornbusch e Krugman, 'Sob a pele de qualquer economista internacional, está enraizada uma fé em alguma variante da teoria da PPP'. O presente estudo se propõe a avaliar as evidências para a PPP a partir de mais de cem anos de história das maiores economias da América Latina. Na literatura, a maior parte dos estudos da PPP no longo prazo utiliza dados de países desenvolvidos (em parte, por causa da disponibilidade dos dados). Taylor (2002) incluiu Argentina, Brasil e México na sua amostra de 20 países desenvolvidos e em desenvolvimento. Há também alguns estudos que tratam especificamente de um ou outro país da região (por exemplo, Délano 1998, que testa a PPP com dados do Chile de 1835 a 1995). Seguindo os métodos usuais descritos na literatura – testes de raiz unitária para se avaliar a estacionariedade da taxa de câmbio real,de aplicação de mecanismos de correção de erro e testes de co-integração – chega-se à conclusão que a evidência obtida a partir dos dados da América Latina é favorável à tese de existência da PPP no longo prazo.

A hipótese de que não existe uma força de convergência agindo sobre o câmbio real ajustado (ARER) foi fortemente rejeitada estatisticamente, e a não-linearidade se mostrou um questão importante. As meia-vidas encontradas para o Brasil usando os modelos padrão parecem ser uma das menores já encontradas para um país, e chegamos à conclusão de que a velocidade de convergência em direção a PPC ainda não pode ser considerada um consenso. Pretendemos, em adição, dar contribuições através do levantamento e esclarecimento de alguns resultados e problemas potenciais concernentes ao estudo da PPC. / In this work we address some unresolved purchasing-power parity (PPP) puzzles; during the process we propose a new nonlinear model and check the role of temporal aggregation and of datasets covering only a small period of time. The hypothesis that there is no convergence force acting on ARER has been strongly statistically rejected and the nonlinearity showed itself as an important issue. The half-lives found for Brazil using standard models seem to be one of the smallest ever found for a country. However, we concluded that the speed of converge towards PPP is not a consensus yet. Besides, we expect to give contributions to PPP literature by pointing out important results and potential pitfalls on PPP research.

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / This work aims to provide non-biased estimates of the speed of reversion of deviations from the PPP for 11 Brazilian cities, between 1991 and 2013, using the methodology proposed by Choi, Mark and Sul (2006), which makes use of a panel estimation method with correction for three possible sources of bias, those being: the bias of inappropriate grouping of cross-section units with heterogeneous coefficients, the Nickell bias and the bias arising from the temporal aggregation of price indexes. The half-lives obtained are of the order of 4.41 and 3.18 years with Brazil and the Average as references, respectively, and median half-life of 3.13 years, when considering all Brazilian cities analyzed as the numeraire. The half-lives found were also substantially lower than those obtained for American cities. Furthermore, 33.33 % of the half-lives obtained were inferior to the consensus range suggested by Rogoff (1996) of 3-5 years, and none surpassed that range. / O presente estudo se propÃe a prover estimativas nÃo viesadas da velocidade de reversÃo dos desvios da PPC para 11 cidades brasileiras entre 1991 e 2013 atravÃs da metodologia proposta por Choi, Mark e Sul (2006) que usam um mÃtodo de estimaÃÃo em painel com correÃÃo para trÃs possÃveis fontes de viÃs, quais sejam, viÃs de agrupamento inapropriado de unidades cross-sections com coeficientes heterogÃneos, viÃs de Nickell e o viÃs oriundo da agregaÃÃo temporal dos Ãndices de preÃos. As meias-vidas obtidas sÃo da ordem de 4.41 e 3.18 anos tendo Brasil e MÃdia como referÃncia, respectivamente, e meia-vida mediana de 3.13 anos considerando todas as cidades brasileiras analisadas como numerÃrio. As meias-vidas encontradas tambÃm se mostraram substancialmente inferiores Ãquelas obtidas para as cidades americanas. AlÃm disso, 33.33% das meias-vidas aqui obtidas se mostraram inferiores ao intervalo consensual proposto por Rogoff (1996) de 3 a 5 anos, e nenhuma o ultrapassou.

nÃo hà / A tese intitulada âTrÃs Ensaios em Macroeconometriaâ à composta de trÃs capÃtulos. O primeiro capÃtulo aplica um modelo em painel dinÃmico para analisar a convergÃncia da taxa de crescimento do PIB per capita, numa abordagem nÃo linear atravÃs de um efeito threshold para os vinte e seis Estados brasileiros mais o Distrito Federal, durante o perÃodo 1985-2005. Os resultados indicam a existÃncia de dois clubes de convergÃncia, um formado pelos estados que se encontram no regime de baixa renda, formado pelos estados da regiÃo nordeste, norte (com exceÃÃo do estado do Amazonas) e o estado de GoiÃs, enquanto que o outro clube à formado por aqueles que se encontram no regime de alta renda, compostos pelos estados da regiÃo sul e sudeste, mais os estados de Mato Grosso, Mato Grosso do Sul e o Distrito Federal. No segundo capÃtulo aplica-se uma formulaÃÃo de tendÃncias comuns Ãs variÃveis PIB real, taxa de juros SELIC nominal, oferta monetÃria do agregado M1 e taxa de inflaÃÃo IPCA, para extrair uma medida de nÃcleo de inflaÃÃo com caracterÃsticas fowardlooking. ApÃs determinar o nÃcleo de inflaÃÃo para o IPCA, testam-se as condiÃÃes para uma medida de nÃcleo segundo Marques et al. (2003) juntamente com duas outras medidas de nÃcleo fornecidas pelo Banco Central do Brasil. Por Ãltimo testam-se a acurÃcia de previsÃes fora da amostra feitas por essas medidas para o IPCA. Os resultados confirmam que a medida de nÃcleo por tendÃncias comuns tem um bom poder preditivo. O terceiro capÃtulo testa a hipÃtese da paridade do poder de compra (PPP) para o Brasil durante o perÃodo de 1985 a 2008 atravÃs da aplicaÃÃo dos testes de raiz unitÃria em painel com dependÃncia transversal apresentados em Moon e Perron (2004) e Pesaran (2007). Utiliza-se como base de dados o Ãndice de inflaÃÃo INPC para nove regiÃes metropolitanas: Belo Horizonte, BelÃm, Curitiba, Fortaleza, Porto Alegre, Recife, Rio de Janeiro, SÃo Paulo e Salvador. Os resultados mostram mudanÃa de persistÃncia apÃs a implementaÃÃo do Plano Real. Enquanto que no perÃodo de alta inflaÃÃo a hipÃtese de Paridade do Poder de Compra PPP à satisfeita, no perÃodo de estabilizaÃÃo de preÃos a PPP nÃo à satisfeita. Este resultado à fortalecido atravÃs da anÃlise das estatÃsticas descritivas dos dados. / The thesis entitled "TrÃs Ensaios em Macroeconometria" is composed of three chapters. The first chapter applies a dynamic panel model to analyze the convergence rate of growth of GDP per capita, non-linear approach using a threshold effect for the twenty-six Brazilian states plus the Distrito Federal during the period 1985-2005. The results indicate the existence of two convergence clubs, one formed by the states that are in the regime of low income, formed by the Northeast region, north (with the exception of the state of Amazonas) and the state of GoiÃs, while other club consists of those who are in the regime of income, formed by the states of South and Southeast, over the states of Mato Grosso, Mato Grosso do Sul and Distrito Federal. The second chapter presents a formulation of common trends in the variables real GDP, nominal interest rate Selic, money supply of M1 and IPCA inflation rate, to extract a measure of core inflation with features foward-looking. After determining the core inflation for the IPCA, we tested the conditions for a measure of core second Marques et al. (2003) along with two other core measures provided by the Banco Central do Brasil. Finally, we tested the accuracy of forecasts out of sample made by these measures to the IPCA. The results confirm that the measure of core inflation by common trends have a good predictive power. The third chapter tests the hypothesis of purchasing power parity (PPP) in Brazil during the period 1985 to 2008 by applying the unit root tests in panel with cross section dependence presented in Moon and Perron (2004) and Pesaran (2007 ). We tested the index of inflation INPC for nine metropolitan areas: Belo Horizonte, BelÃm, Curitiba, Fortaleza, Porto Alegre, Recife, Rio de Janeiro, SÃo Paulo and Salvador. The results show a change in persistence after the Plano Real. While in the period of high inflation the PPP is satisfied, the period of stabilization of prices to PPP is not satisfied. This result is strengthened by examining the descriptive statistics of the data.

La théorie quantitative de la monnaie reliant systématiquement la croissance de la masse monétaire en circulation et la hausse généralisée des prix, est l’une des conceptions les plus anciennes en science économique. Après avoir fait l’objet de multiples controverses selon les époques, elle semble aujourd’hui peu préoccuper l’attention des économistes. Les désaccords portèrent souvent sur la dichotomie, la neutralité de la monnaie, la proportionnalité de la relation monnaie-Prix, les propriétés de la fonction de demande de monnaie, et sur l’éxogénéité de l’offre de monnaie. Cette théorie influence officieusement la conduite de la politique monétaire de la plupart des banques centrales qui se fixent des mesures conventionnelles de contrôler la quantité de monnaie pour limiter l’inflation. Dans de nombreux manuels d’économie, la théorie quantitative est encore mobilisée pour expliquer les hausses généralisées des prix.En recourant aux méthodes de l’économie politique qui consistent à opposer les faits et la théorie des économistes, notre thèse consiste à proposer une évaluation critique des doctrines monétaires quantitativistes dans l’interprétation des crises historiques de hausse des prix. Notre démarche s’appuie en particulier sur une réinterprétation factuelle de deux grandes crises des prix connues où nous cherchons à voir si la théorie quantitative y est exclusivement pertinente. Ainsi la « révolution des prix » du XVIe en Europe et l’hyperinflation allemande sont deux épisodes d’une crise des prix où la théorie quantitative s’avère insuffisante pour expliquer les problèmes étudiés. Pourtant la conception quantitativiste de la monnaie s’est beaucoup métamorphosée au fil du temps, s’appuyant à chaque fois sur les corpus théoriques de l’équilibre et de la valeur, solidaires d’une unité méthodologique assise sur la dichotomie. Notre thèse est revenue de manière critique et détaillée sur toutes les facettes de cette métamorphose, à partir de la contribution des auteurs classiques jusqu’aux néoclassiques, tout en mettant un accent sur l’apport de Keynes, pour rendre compte de la longue continuité de la pensée quantitative dans la science économique. / The Quantity Theory of money which always links the increase in the high-Powered money supply and the general rise in prices is one of the oldest concepts in economics. After to have been the subject of many controversies at different times, it seems nowadays to hold less attention from the economists because the dispute is dissipated in a kind of religious choice to believe or not to believe to quantity theory. This theory officially influences the monetary policy of most of central banks in the world that bind conventional measures to control the money supply to curb inflation process. In many orthodox economics’ textbooks, the quantity theory is still deployed in perpetuum to explain the price crisis in history.By using the methods of political economy, we will counterbalance the economic facts like they are recorded and the economic theory; our thesis aims to provide a critical assessment of orthodox monetary doctrines based on the quantity theory, in the interpretation of historical price crises. Our approach relies on a factual reinterpretation of two major historical price crises in Europe, and we will seek to see if the quantity theory is relevant. Thereby, the “price revolution” of the sixteenth in Europe and the German hyperinflation are two periods of price crisis where the quantity theory is insufficient to explain all sides of the problem studied. Yet the quantity conception of money is much transformed over time, based each time on the doctrines of equilibrium and value. Our thesis is back critically in details on all aspects of this transformation: the contribution from the classics until the neoclassical School, all with a focus on the contribution of Keynes, to account for the long survival of quantity thinking in monetary economics.

This thesis is focused on the description of the purchasing power parity theory and the theory of the interest rate as the fundamental aspects of exchange rate movements. A large part is devoted to the problems of equilibrium exchange rates and associated anomalies that these equilibrium rates are largely affected. The aim is to highlight the pros and cons of these theories and their practical use in nowadays world. Incomplete validity of purchasing power parity is analyzed by using available data which also leads to examine the presence of deviation from the equilibirum value. These anomalies are divided into economic origin anomalies and anomalies arising from non-market intervention. Despite the frequent critism the theory of purchasing power parity is still the most popular and frequently published theory.
