Testamos a equação clássica da PDJ usando o Método dos Mínimos Quadrados Ordinários. Após a estimação dos parâmetros, aplicamos o Teste de Wald e verificamos que a paridade descoberta de juros não foi validada. Estendemos a equação tradicional da PDJ para uma especificação alternativa que captura medidas de risco Brasil e de alteração na liquidez internacional. Especificamente, acrescentamos três variáveis de controle: duas variáveis dummy que capturam condições de liquidez externa e o índice de commoditie CRB, que captura o risco Brasil. Com a especificação alternativa, a hipótese de que os retornos das taxas de juros em Real, dolarizadas, são iguais aos retornos da taxas de juros contratadas em dólares, ambas sujeitas ao risco Brasil, não foi rejeitada. Em complemento à análise das taxas representativas do mercado brasileiro, procurou-se avaliar a predominância da PDJ nas operações de swap cambial realizadas pela Vale S.A.. Para tanto, a série de taxa de juros em dólares do mercado brasileiro foi substituída pela taxa em dólar dos swaps contratados pela Vale. Os resultados encontrados demonstram que, quando comparado ao comportamento do mercado, as taxas em dólares da VALE são mais sensíveis às variações das taxas em Reais. / We measure the validity of uncovered interest parity - UIP - for the Brazilian market from January, 2010 to July, 2014. We tested the classical equation of UIP using the ordinary least squares method. After the estimation, we apply the Wald test and we verify that the uncovered interest parity has not been validated. We extend the traditional UIP equation for an alternative specification that captures Brazil risk and changes in liquidity of the international market. Specifically, we add three control variables: two dummy variables that capture external liquidity conditions and the commodity index CRB, which captures Brazil risk. With the alternative specification, the hypothesis that the returns in interest rates in Real, dollarized, are equal to the return of interest rate contracted in dollars, both subject to Brazil risk, was not rejected. To complement the analysis using the interest rates existing in the Brazilian market, we tried to evaluate the prevalence of UIP in cross currency interest rate swaps carried out by Vale SA. The interest rate in dollar of the Brazilian market was replaced by the dollar rate of swaps contracted by Vale. The results show that, when compared to market behavior, the dollar rates of Vale SA. are more sensitive to changes in Reais interest rates.

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.

After an analysis of the relevant literature and considering the current availability of options data – a recent development – the HIP is proposed. The way the model fits the traditional framework is promising from a theoretical standpoint: the HIP can be seen as a linear combination of the CIP (covered interest parity) and the UIP, converging to one or another depending on the parameters chosen. Besides that, it can help explain help understand the effects of learning and the peso problem in the unexpected values found in traditional regression results. On top of that, the HIP generates a functional form for the FX risk premium that can be empirically tested. This essay also proposes and implements a comparative evaluation of the HIP, with encouraging results. In addition to positive coefficients for the forward premium, the HIP shows a risk premium with characteristics that confirm Fama’s propositions. Hence it allows one to conclude that the investigation of the forward discount puzzle including data on options is a fertile path for future research. The work also brings important policy implications. / Este trabalho propõe a modelagem da paridade hedgeada de juros (HIP, hedged interest parity) – uma alternativa ao uso da paridade descoberta de juros (UIP, uncovered interest parity) que faz uso de opções sobre a taxa de câmbio e pode ser usada no estudo de um dos puzzles ainda não resolvidos na teoria econômica: a não ausência de viés no mercado futuro de câmbio como indicador das expectativas dos agentes. Através das pistas encontradas na revisão da vasta literatura disponível sobre o assunto e considerando a disponibilidade atual de dados sobre o mercado de opções – uma novidade recente - a HIP é proposta. A forma com que a modelagem usando opções se encaixa no framework tradicional é animadora do ponto de vista teórico: a HIP pode ser vista como uma forma genérica que, dependendo dos parâmetros escolhidos, converge para a CIP (covered interest parity) ou para a UIP (uncovered interest parity). Além disso, ela mitiga efeitos de duas das principais explicações tradicionais para as falhas dos testes da UIP, i.e. learning e peso problem, o que a torna potencialmente melhor do que esta como modelo para o estudo das paridades de juros. Mais importante do que isso, ela sugere uma forma funcional para o prêmio pelo risco cambial (PRC) que pode ser testada econométricamente. O ensaio também propõe e implementa um teste comparativo da HIP com a UIP com resultados animadores. Além do coeficiente do forward premium mudar para mais próximo do previsto pela teoria quando se troca a UIP pela HIP, o prêmio pelo risco cambial gerado pela modelagem da HIP apresenta resultados próximos aos previstos por Fama(1984). Isso permite concluir que a investigação do prêmio pelo risco cambial usando os dados do mercado de opções é um caminho fértil para pesquisa futura. O trabalho traz ainda conclusões importantes para a implementação de política monetária, uma vez que propõe a inclusão da volatilidade implícita do câmbio (via custos das opções) na equação de paridade de juros.

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.

The classical Fama regressions view, applied to the cambial free float suggests rejection of this hypothesis when 12-month NDF contracts in Real Currency (BRL) are taken into consideration, identifying bias on the future contracts as estimators for exchange rate – it was not possible to obtain the same conclusion when working with 30-day USD future contracts dealt at BM&F. Once done the Fama regressions, it is applied into the Brazilian case the methodology implemented for developed countries by Clarida et. al (2009), in order to capture eventual relationship between volatility and excess of return in a carry trade strategy with Reais. As well as the results obtained off the international experience, it is noted negative correlation between volatility and excess of return of such strategy. From this conclusion on, Fama regressions are tested into subperiods, according to their respective volatilities. Periods of higher volatility were characterized for a Fama regression coefficient increment, once again aligned to the result obtained by Clarida et. al. (2009). Once the subject related to Fama regression is stressed out, we move onto the currency risk premium series estimative through the Kalman Filter methodology, applied to the 12-month NDF series, which pointed out a currency risk premium with positive average on the sampling taken into consideration – aligned with the intuition – but with dispersion measures highly elevated. The study remains trying to model the currency risk premium through a GARCH-M’s family model, being, however, unable to provide good estimative for the variable studied. A new chapter is started in order to introduce microfundamentation to the currency risk premium, bringing to the Brazilian case a method developed by Frankel (1982). The adherence of this model was low as well. In order to finish, it is presented a preliminary investigation about the relationship between currency risk premium and the presence of events considered rare into the PTAX series, following idea brought up by Rietz (1988) and expanded by Barro (2005). The Brazilian currency carries kurtosis that is superior to the other currencies taken into consideration on this sampling, thus indicating that the currency risk premium demanded in order to be positioned in domestic currency may be related to the recurrence of supposedly rare events. / Este trabalho se propõe a testar a validade da hipótese da paridade câmbio-juro para o caso brasileiro e, posteriormente, a investigar a principal explicação apontada pela literatura para a falência da UIP, qual seja: a existência de um prêmio de risco cambial variante ao longo do tempo. A clássica abordagem das regressões de Fama, aplicadas para o período de livre flutuação cambial, sugere falência da hipótese em questão quando considerados contratos de NDF de doze meses sobre o real, identificando viés nos contratos futuros como estimadores da taxa de câmbio – não foi possível obter a mesma conclusão ao se trabalhar com contratos futuros de dólar de um mês negociados na BM&F. Feitas as regressões de Fama, replica-se ao caso brasileiro metodologia implementada por Clarida et. al. (2009) para os países desenvolvidos, na tentativa de capturar eventual relação entre a volatilidade e o excesso de retorno de uma estratégia de carry trade com o real. Em linha com os resultados obtidos pela experiência internacional, detecta-se correlação negativa entre a volatilidade e o excesso de retorno de tal estratégia. A partir de tal conclusão, revisitam-se as regressões de Fama para subperíodos, conforme a volatilidade. Períodos de maior volatilidade foram caracterizados por um incremento do coeficiente da regressão de Fama, novamente em um resultado alinhado àquele obtido por Clarida et. al. (2009). Esgotado o assunto circunscrito às regressões de Fama, passa-se à estimativa da série de prêmio de risco cambial propriamente dita, por meio da metodologia de Filtro de Kalman imposta à série de NDF de doze meses, a qual detectou um prêmio de risco cambial com média positiva na amostra considerada – em linha com a intuição -, mas com medidas de dispersão bastante elevadas. O estudo segue numa tentativa de modelar o prêmio de risco cambial através de um instrumental da família GARCH-M, sendo, entretanto, incapaz de prover boas estimativas para o comportamento da variável sob interesse. Inicia-se um novo capítulo com o intuito de introduzir microfundamentação ao prêmio de risco cambial, trazendo ao caso brasileiro método desenvolvido por Frankel (1982). A aderência da modelagem também foi baixa. Para terminar, apresenta-se investigação preliminar sobre a relação entre o prêmio de risco cambial e a presença de eventos considerados raros na série de PTAX, seguindo intuição levantada por Rietz (1988) e expandida por Barro (2005). A moeda brasileira carrega caráter leptocúrtico superior às demais componentes da amostra, indicando que, de fato, o prêmio de risco cambial exigido para se estar na moeda doméstica pode estar relacionado à recorrência de eventos supostamente raros.

-Les dynamiques du taux de change en présence de frictions sur les marchés financiers.Cette analyse est une extension du modéle du surajustement « Overshooting » de Dornbusch. Il s'éloigne du modéle de base en faisant l'hypothèse que les marchés financiers ne s'ajustent pas instantanément, « generalised interest parity condition ». Le modele de taux de change sous cette hypothèse, reproduit le surajustement retarde du taux de change nominal. Notre modele arrive aussi a capturer la variation en forme de bosse du taux de change reel et suite a un choc monetaire.-Électorale Cycle de taux de change en CoréeCe papier analyse empiriquement les variations du taux de change reel en Coree du Sud, a l'approche des elections et un peu apres de celles-ci. Nous remarquons que le taux de change baisse juste avant les election mais nous n'avons pu deceler de tendance nette apres. Ce resultat est a l'oppose de celui trouve lors de l'étude des cycles électorales en Amérique latine. Nous expliquons cette divergence par des différences dans la structure économique entre la Corée du Sud et les pays d'Amerique latine-Le régime de change, l'ouverture des marchés de la capitale et de la politique monétaire; Le trilemme en CoréeCet article teste la proposition trilemme en effectuant une étude empirique de Corée. La Corée possède périodes distinctes de toutes les combinaisons de régime de taux de change et l'ouverture du marché des capitaux dans le trilemme: rattaché au régime de taux de change sous le contrôle des capitaux, rattaché au régime de taux de change sous libre circulation des capitaux et des taux de change flottant régime en vertu libre circulation des capitaux. Nous vérifions si l'autonomie monétaire existe dans chacune des trois combinaisons différentes. Nous constatons que l'autonomie monétaire existé au cours des périodes où les contrôles de capitaux et les périodes de régime de taux de change flottant. Pour les périodes avec le régime de parité fixe et libre circulation des capitaux, l'autonomie monétaire a été limitée. En outre, nous identifions que, juste avant la crise financière, le gouvernement a poursuivi la politique monétaire autonome sous le régime de taux de change arrimé et libre circulation des capitaux, défiant ainsi le trilemme. / -Exchange Rate Dynamics under Financial Market FrictionsThis paper extends Dornbusch's overshooting model by proposing “generalized interest parity condition”, which assumes sluggish adjustment on the asset market. The exchange rate model under the generalized interest parity condition is able to reproduce the delayed overshooting of nominal exchange rates and the hump-shaped response to monetary shocks of both nominal and real exchange rates.-Electoral Cycle of Exchange Rate in KoreaThis paper empirically investigates the real exchange rate behavior around elections in Korea. We find that the real exchange rate depreciates more before the elections but there is no clear pattern found after the elections. Interestingly, this result is the opposite of the electoral cycle found in Latin American countries. To explain this results we should consider the difference between economic backgrounds of Korea and Latin American countries.-Exchange Rate Regime, Capital Market Openness and Monetary Policy; The Trilemma in KoreaThis paper tests the trilemma proposition by performing an empirical study of Korea. Korea has distinct periods of all combinations of exchange rate regime and capital market openness in trilemma: pegged exchange rate regime under capital controls, pegged exchange rate regime under free capital mobility, and floating exchange rate regime under free capital mobility. We check whether monetary autonomy exists in each of the three different combinations. We find that monetary autonomy existed over the periods with capital controls and the periods with floating exchange rate regime. For the periods with the pegged exchange rate regime and free capital mobility, monetary autonomy was limited. In addition, we identify that just before the financial crisis the government pursued autonomic monetary policy under pegged exchange rate regime and free capital mobility, thereby defying the trilemma.

The evaluation of influence of parity on fatty acids content in milk fat of cows from selected farm and defining of difference between lactations were main topics of this thesis.

The objective of the thesis was the analysis of reproductive traits of sows. Data from the years 2009?2011 were obtained in the company conducting production herds. The highest number of piglets born alive per one sow a year (26.8) was reached in 2011. The highest number of weaned piglets (25.6) per a sow was obtained in 2010. By shortening farrowing index in a monitored three-year period the number of births increased from 2.29 to 2.35. We found out that sows covered at older age gave birth to more piglets born alive. Concerning total number born piglets the difference between sows covered in more than 246 days and sows covered in the age interval of 225?246 days was 0.14 piglets, or, as the case may be, with sows covered in 203?224 days the difference was 0.18 piglets. Sows covered in less than 203 days gave birth only to 10.67 total number born piglets. Most total number born piglets were found at the sixth litter (13.14), followed by the fourth litter. The fourth litter brought most alive-born piglets (12.58) and differed from the third litter only slightly. Most piglets survived at the third litter (11.61). The relation between all piglets and those alive-born was statistically highly conclusive 0.859+++. The highest number of total number born piglets was reached with sows which were covered 5 (12.84) or 6 days (12.79) after weaning.

Milk fat is the recipient of numerous functions. It affects the biological, chemical, sensory and technological properties of milk. The Czech Republic is consumed and processed, especially cows, goats and ewes milk. The aim was to focus on the description of selected fatty acids in milk fat of dairy cows and goats because of their importance to human health and the factors that influence their composition. The results show that the content of short-chain fatty acids was compared to dairy cows higher in goat breeds. It was also found that the proportion of saturated fatty acids was influenced mainly breed and individuality, while the composition of unsaturated fatty acids was affected more nutrition and feeding. The work describes the biological factors such as breed, individuality, parity and stage of lactation, of the external factors described nutrition and feeding. Chapter biological factors mainly deals with the influence of genetics and contains a description of selected candidate genes affecting milk fat and fatty acids.

Les véhicules modernes sont de plus en plus équipés de nouveaux organes visant à améliorer la sécurité des occupants. Ces nouveaux systèmes sont souvent des organes actifs utilisant des données de capteurs sur le véhicule. Cependant, en cas de mauvais fonctionnement d'un capteur, les conséquences pour le véhicule peuvent être dramatiques. Afin de garantir la sécurité dans le véhicule, des nouvelles méthodologies de détections de défauts adaptées pour les véhicules sont proposées. Les méthodologies présentées sont étendues de la méthode de l'espace de parité pour les systèmes à paramètres variant (LPV). En outre, la transformation du problème de détection de défauts pour la détection de situations critiques est également proposée. Des résultats applicatifs réalisés sur un véhicule réel dans le cadre du projet INOVE illustrent les performances des détections de défauts et la détection de perte de stabilité du véhicule. / Modern vehicles are increasingly equipped with new mechanisms to improve occupant safety. These new systems are often active parts using data from sensors on the vehicle. However, in case of malfunction of a sensor, the consequences for the vehicle can be dramatic. To ensure safety in the vehicle, new methodologies for detection of faults suitable for vehicles are proposed. The developed methodologies are extended from the method of parity space for linear parameter varying systems (LPV). In addition, the transformation of fault detection problem for the detection of critical situations is also available. Application of results achieved on a real vehicle within the INOVE project illustrate the performance of fault detection and detection of loss of stability of the vehicle.
