The purpose of this study was to determine the informational value of FASB Statement No. 33 current cost disclosures using the analytical technique of industry-wide decomposition analysis. The industry-wide decomposition model was used to measure the informational content of both the historical cost balance sheets (reported in the firm's annual reports) and the current cost balance sheets (prepared from the current cost disclosures) of firms in the Electric Services and Retailers industries. The two measures were then compared to determine the informational value of FASB Statement No. 33 current cost disclosures.

Para tanto, foram realizados dois desenvolvimentos teóricos, em que no primeiro se fez uso do desenvolvimento de Demertzis e Hallet (2007) com o arcabouço teórico da curva de oferta de Lucas como restrição, enquanto o segundo utilizou o arcabouço teórico da curva de Phillips novo-keynesiana que, além de contar com a função perda do banco central, incorpora a função perda dos agentes, passando estes a serem afetados diretamente pelas decisões da autoridade monetária. Cabe ressaltar que nos desenvolvimentos realizados houve uma modificação crucial em relação à literatura no que tange a importância da transparência no ambiente econômico, usualmente avaliada sobre a trajetória das variáveis econômicas e suas variâncias, conforme resultados de Demertzis e Hallet (2007). Contudo, nesta dissertação, a importância da transparência incide essencialmente sobre a incerteza dos agentes econômicos em relação à inflação futura através dos erros de previsão destes, baseado fundamentalmente nos pressupostos de Lahiri e Sheng (2010), em que os agentes econômicos no caso brasileiro são representados pelos participantes da pesquisa Focus. Dado o arcabouço utilizado no primeiro modelo, as relações teóricas encontradas não apontaram importância da transparência sobre a incerteza inflacionária dos indivíduos, sendo esta medida afetada essencialmente pelos choques de oferta da economia. No entanto, no que concerne ao exercício empírico, os resultados sugerem que uma parcela substancial da variabilidade observada na incerteza individual não é explicada pela variação observada nos choques de oferta, havendo, portanto, a possibilidade de que outros fatores possam ser incorporados, uma vez que o modelo teórico sugere que, caso os agentes não enfrentem problemas de comunicação com a autoridade monetária, os choques de oferta deveriam ser a origem da incerteza individual. Desta forma, existe espaço para explorarmos o problema considerando um novo arcabouço teórico representado pela curva de Phillips novo-keynesiana, que permitiu a inserção da discussão da transparência sobre a incerteza inflacionária dos agentes. Os resultados empíricos comprovaram as relações teóricas apresentadas, ou seja, a variável referente à transparência política do banco central foi assaz importante na explicação da incerteza inflacionária dos agentes durante o período de interesse. / This study aimed to analyze the relation between inflation uncertainty and transparency of the central bank within the period of inflation targeting, from July 2003 to May 2010. Therefore, there were two theoretical developments, in which the first was made use of development Demertzis and Hallet (2007) with the theoretical framework of the Lucas supply curve as restriction, while the second used the theoretical framework of the new-Keynesian Phillips curve, in addition to the central bank’s loss function, incorporates loss function of the agents, passing these to be directly affected by the decisions of the monetary authority. Note that the developments made there was a crucial change from the literature regarding the importance of transparency in the economic environment, usually evaluated on the trajectory of economic variables and their variances, according to results of Demertzis and Hallet (2007). However, in this work, the importance of transparency essentially concerns the uncertainty of economic agents regarding future inflation through the forecast errors of these fundamentally based on the assumptions of Lahiri and Sheng (2010), in which economic agents in the Brazilian case are represented by the research participants Focus. Given the framework used in the first model, the theoretical relationships found not pointed importance of transparency on inflation uncertainty of individuals, and this measure is affected primarily by supply shocks in the economy. However, regarding the empirical exercise, the results suggest that a substantial portion of the variability in the individual uncertainty is not explained by variation in the supply shocks observed, and therefore there is the possibility that other factors can be incorporated once the theoretical model suggests that if the agents do not face communication problems with the monetary authority, the supply shocks should be the origin of individual uncertainty. Thus, there is room to explore the problem considering a new theoretical framework represented by the new-Keynesian Phillips curve, which allowed the insertion of the discussion of transparency on inflation uncertainty of the agents. The empirical results confirm the theory with the relations, that is, the variable on the central bank policy transparency was quite important in explaining inflation uncertainty of the agents during the period of interest.

This work aims to contribute to the wider body of research in history of economics in Brazil by focusing on the conceptual evolution of inflation inertia. Its motivation lies in the conceptual gap that appeared, following disinflation in 1994, between the stabilization debates carried out in the 1980s and the way economists in Brazil began to describe downwardly rigid inflation patterns from the 1990s onwards. More precisely, we explore the \"inertial inflation episode\" as a chapter in a longer tradition of adaptations, to country-specific realities, of theoretical influences coming from the economics profession at the international level, in the late 1970s, when the inertial inflation hypothesis was brought to the fore. Our narrative reveals that this stubborn inflationary phenomenon had been previously dealt with in the debates in Latin America about growth and inflation back in the 1950s and 1960s, where a host of contributions sprung from various traditions, which were gradually synthesized by the saw-tooth model of real wages, also known as Simonsen-Pazos mechanism. We analyze the recurrent opposition between a monetarist- and a heterodox structuralist-type of thinking in their two rounds, in the 1950s and again in the 1980s. The connection between these two opposing schools is operated by the contributions by Mario Henrique Simonsen and the self-declared neo-structuralist economists at PUC-Rio. Based on a careful and detailed analysis of the latter\'s modeling strategies and conclusions, we show that, along the 1980s, these economists gradually shift towards a more ecumenical approach, inviting monetarist elements into their analyses while downplaying the relevance of the inertial component. Finally, when the 1990s came, the rise of a macroeconomic consensus began to conceptualize \"inflation inertia\" as the time delay between a real or monetary shock and the response by price level changes, leaving the concept of \"inflation persistence\" to account for the deviations of inflation away from its equilibrium value, a view that undergirds how most Brazilian economists now understand this phenomenon. We assess how \"inflation inertia\" has been understood in the aftermath of the monetary reform in Brazil in 1994, by analyzing the backstage papers that circulated within the economic team in charge of the Real Plan. We conclude that there are elements of continuity between the two rounds as regards the concept of inertia, but that they are now stripped of their previous dense historical and institutional substance. / O presente trabalho busca contribuir para a literatura de história do pensamento econômico brasileiro, ao estudar a transformação do conceito de inércia inflacionária no Brasil desde os debates sobre estabilização na década de 1980 até o período pós-Real, mudança essa que permanece inexplicada pela literatura. Mais precisamente, o trabalho busca verificar a hipótese de que a inflação inercial não passou de um episódio de uma longa tradição de adaptações teóricas de influências oriundas de economistas estrangeiros, em especial na década de 1970, quando a hipótese de uma inflação inercial foi levantada. Nossa narrativa revela que o fenômeno da rigidez inflacionária já havia sido previamente compreendido e teorizado nos debates na América Latina, nas décadas de 1950 e 1960, quando inúmeras contribuições foram eventualmente sintentizadas no modelo de rendas contratuais sob inflação no formato de \"dente-de-serra\", ou o assim chamado mecanismo Simonsen-Pazos. A narrativa adota a controvérsia entre monetaristas e estruturalistas em seus dois momentos como eixo da análise, para mostrar como o desaparecimento dessa oposição coincide com a emergência do consenso macroeconômico em escala internacional. Baseando-se em uma análise cuidadosa e detalhada das contribuições dos economistas neo-estruturalistas da PUC-Rio e da onipresente influência de Simonsen como um sintetizador das contenciosas escolas, o trabalho apresenta evidências documentais de uma transformação estruturalista da segunda geração. Ao longo dos anos 1980, esses economistas gradualmente convergiram para uma abordagem mais ecumênica com relação aos monetaristas, reduzindo a importância do componente inercial da inflação e ampliando a relevância de aspectos usualmente associados à ortodoxia econômica. Finalmente, no período pós-Real, passa a predominar no país um conceito de inércia inflacionária que constrasta com a visão anterior dos economistas atuando no referido plano de estabilização. Esse novo conceito está associado à emergência da \"nova síntese neoclássica\", na qual a inércia é compreendida como o atraso na resposta dos níveis de preço a choques monetários ou reais, enquanto o conceito de persistência inflacionária representa desvios duradouros da inflação com relação ao seu nível de equilíbrio. Para compreender se essa mudança pode ser considerada uma ruptura com relação ao passado, analisam-se os artigos que circularam nos bastidores do Plano Real dentro da equipe econômica. Nosso trabalho conclui que há elementos de continuidade entre os dois momentos no que se refere ao conceito de inércia, os quais aparecem agora com uma representação analítica desprovida da substância histórica e institucional que o conceito outrora abarcava.

Face au déclin global de la biodiversité, de nombreux suivis de populations animales et végétales sont réalisés sur de grandes zones géographiques et durant une longue période afin de comprendre les facteurs déterminant la distribution, l’abondance et les tendances des populations. Ces suivis à larges échelles permettent de statuer quantitativement sur l’état des populations et de mettre en place des plans de gestion appropriés en accord avec les échelles biologiques. L’analyse statistique de ce type de données n’est cependant pas sans poser un certain nombre de problèmes. Classiquement, on utilise des modèles linéaires généralisés (GLM), formalisant les liens entre des variables supposées influentes (par exemple caractérisant l’environnement) et la variable d’intérêt (souvent la présence / absence de l’espèce ou des comptages). Il se pose alors un problème majeur qui concerne la manière de sélectionner ces variables influentes dans un contexte de données spatialisées. Cette thèse explore différentes solutions et propose une méthode facilement applicable, basée sur une validation croisée tenant compte des dépendances spatiales. La robustesse de la méthode est évaluée par des simulations et différents cas d’études dont des données de comptages présentant une variabilité plus forte qu’attendue (surdispersion). Un intérêt particulier est aussi porté aux méthodes de modélisation pour les données ayant un nombre de zéros plus important qu’attendu (inflation en zéro). La dernière partie de la thèse utilise ces enseignements méthodologiques pour modéliser la distribution, l’abondance et les tendances des rapaces diurnes en France. / In the context of global biodiversity loss, more and more surveys are done at a broad spatial extent and during a long time period, which is done in order to understand processes driving the distribution, the abundance and the trends of populations at the relevant biological scales. These studies allow then defining more precise conservation status for species and establish pertinent conservation measures. However, the statistical analysis of such datasets leads some concerns. Usually, generalized linear models (GLM) are used, trying to link the variable of interest (e.g. presence/absence or abundance) with some external variables suspected to influence it (e.g. climatic and habitat variables). The main unresolved concern is about the selection of these external variables from a spatial dataset. This thesis details several possibilities and proposes a widely usable method based on a cross-validation procedure accounting for spatial dependencies. The method is evaluated through simulations and applied on several case studies, including datasets with higher than expected variability (overdispersion). A focus is also done for methods accounting for an excess of zeros (zero-inflation). The last part of this manuscript applies these methodological developments for modelling the distribution, abundance and trend of raptors breeding in France.

Hybrid models of inflation are particularly interesting and well motivated, since easily embedded in various high energy frameworks like supersymmetry/supergravity, Grand Unified Theories or extra-dimensional theories. If the original hybrid model is often considered as disfavored, because it generically predicts a blue spectrum of scalar perturbations, realistic hybrid models can be in agreement with CMB observations. The dynamics of hybrid models is usually approximated by the evolution of a scalar field slowly rolling along a nearly flat valley. Inflation ends with a waterfall phase, due to a tachyonic instability. This final phase is usually assumed to be nearly instantaneous. <p> <p>In this thesis, we go beyond these approximations and analyze the exact 2-field non-linear dynamics of hybrid models. Several non trivial effects are put in evidence: 1) the possible violation of the slow-roll conditions along the valley induce the non existence of inflation at small field values. Provided super-planckian fields, the scalar spectrum of the original model is red, in agreement with CMB observations, independently of the position of the critical instability point. 2) Contrary to what was thought, the initial field values leading to inflation are not fine-tuned along the valley but also occupy a considerable part of the field space exterior to it. They form a complex connected structure with fractal boundaries that is the basin of attraction of the valley. Using bayesian methods, their distribution in the whole parameter space, including initial velocities, is studied. Natural bounds on the potential parameters are derived. 3) For the original model, after the field evolution along the valley, inflation continues for more than 60 e-folds along the waterfall trajectories in some part of the parameter space. Observable predictions are modified, and the scalar power spectrum of adiabatic perturbations is generically red, possibly in agreement with CMB observations. Moreover, topological defects are conveniently stretched outside the observable Universe. 4) The analysis of the initial conditions is extended to the case of a closed Universe, in which the initial singularity is replaced by a classical bounce. Contrary to some other scenarios, due to the attractor nature of the valley, the field values in the contracting phase do not need to be extremely fine-tuned to generate a bounce followed by a phase of hybrid inflation. <p> <p>In the third part of the thesis, we study how the present CMB constraints on the cosmological parameters could be ameliorated with the observation of the 21cm cosmic background from the dark ages and the reionization, by the future generation of giant radio-telescope. Assuming ideal foreground removals, forecasts on the cosmological parameters are determined for a characteristic Fast Fourier Transform Telescope experiment, by using both Fisher matrix and MCMC methods. / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

This paper uses the semi-structural Laubach and Williams model to estimate the time- varying natural rate of interest by Kalman filter and Maximum Likelihood method, applying it for the first time to Czech data. The results show a significant decrease of the natural interest rate during the past decade, which constitutes further evidence for the wide-spread notion that structural factors in many countries have shifted after the global financial crisis. The paper's contribution is mainly represented by preparing ground for further research. It concludes that the basic version of the Laubach and Williams model is not optimal for the Czech environment and suggests appropriate adjustments to it. It discusses and analyzes sources of potential problems with the estimation, notably the issues of singularity and model specification. Eventually the paper concludes that due to the low significance of results and the uncertainty of gains and losses related to a policy switch, the best reaction of the central bank would be to keep the current regime and inflation target.

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.

The aim of this thesis is to analyze impacts of monetary policy of Czech national bank on the Czech economy since 1993 to 2015. Last few years monetary policy has been often discussed topic in Czech republic. Instruments of monetary policy have been changing and it will be changed again. In this conditions the analysis of entire period of CNB existence is very attractive for author. The theoretical part of the thesis deals with economic theory of central bank. In this part the thesis talks in detail about the regimes of monetary policy and it is focusing on the inflation targeting. The practical part of the thesis deals with analysis of monetary policy in every year in terms of meeting the targets and their impact on the economy. The conclusion of this analysis is to evaluate the effectiveness of monetary policy from 1993 to the present.
