Welfare characterization of monetary-applied models and three implications

This paper demonstrates that the applied monetary models - the Sidrauski-type models and the cash-in-advance models, augmented with a banking sector that supplies money substitutes services - imply trajectories which are Pareto-Optimum restricted to a given path of the real quantity of money. As a consequence, three results follow: First, Bailey’s formula to evaluate the welfare cost of inflation is indeed accurate, if the longrun capital stock does not depend on the inflation rate and if the compensate demand is considered. Second, the relevant money demand concept for this issue - the impact of inflation on welfare - is the monetary base. Third, if the long-run capital stock depends on the inflation rate, this dependence has a second-order impact on welfare, and, conceptually, it is not a distortion from the social point of view. These three implications moderate some evaluations of the welfare cost of the perfect predicted inflation.

Uma investigação das relações familiares na peça "Do Fundo do Lago Escuro (Assunto de Família)", de Domingos de Oliveira

A partir de três conceitos fundamentais para a compreensão da dinâmica das relações familiares: a pseudo-mutualidade, elaborada por Wynne, nos Estados Unidos, o postulado fusional, desenvolvido por Hochmann, na França e a mistificação, por Laing, na Inglaterra, investigou-se a estrutura de relações familiares em um texto teatral brasileiro, atual, "Do Fundo do Lago Escuro", de Domingos de Oliveira. Os três conceitos acima citados, fundamentais para a compreensão da dinâmica das relações familiares dentro de uma perspectiva sistêmica (não-psicanalítica),estão interrelacionados entre si e surgiram apartir de estudos realizados com famílias com um membro esquizofrênico, em três diferentes paises. Buscou-se estabelecer os pontos de contato, as divergências metodológicas, teóricas e ideológicas e os aspectos complementares dos referidos conceitos, bem como verificar sua aplicabilidade a uma estrutura familiar considerada representativa de certa parcela da sociedade brasileira, em determinada ocasião. Concluiu-se pela aplicabilidade dos conceitos, desenvolvidos em três diferentes países, a uma dada estrutura familiar brasileira em um dado momento histórico, e pela aplicabilidade dos conceitos a um grupo familiar que não apresenta, através de qualquer de seus membros, um quadro esquizofrênico manifesto.

O arquivo pessoal do teatrólogo Augusto Boal: o espetáculo continua

A presente pesquisa apresenta a história arquivística do arquivo pessoal do teatrólogo Augusto Boal, destacando os lugares pelos quais o acervo passou até chegar ao seu destino. Destaca os investimentos públicos canalizados para o acervo em questão, como o propósito de fundar um Centro Interuniversitário de Memória e Documentação (CIM). Discute, também, considerações referentes à organização de arquivos pessoais, salientando a importância do tratamento estar pautado em princípios e métodos da arquivística. Além disso, a pesquisa descreve os procedimentos aplicados na sistematização, em curso, deste acervo pessoal, sugerindo um modelo alternativo de organização, com o objetivo de contribuir para seu acesso e difusão.

Essays in applied microeconomics

Esta tese é composta de três artigos. No primeiro artigo, ``Risk Taking in Tournaments", é considerado um torneio dinâmico no qual jogadores escolhem como alocar seu tempo em atividades que envolvem risco. No segundo artigo, ``Unitização de Jazidas de Petróleo: Uma Aplicação do Modelo de Green e Porter" é analisado a factibilidade de se haver um acordo de cooperação em um ambiente de common-pool com incerteza nos custos das empresas. No terceiro artigo, ``Oilfield Unitization Under Dual Fiscal Regime: The Regulator Role over the Bargaining", por sua vez, é estudado a unitização quando existem dois regimes fiscais distintos, como os jogadores se beneficiam disso e o papel do regulador no regime de partilha.

Essays in applied econometrics

Using a unique dataset on Brazilian nominal and real yield curves combined with daily survey forecasts of macroeconomic variables such as GDP growth, inflation, and exchange rate movements, we identify the effect of surprises to the Brazilian interbank target rate on expected future nominal and real short rates, term premia, and inflation expectations. We find that positive surprises to target rates lead to higher expected nominal and real interest rates and reduced nominal and inflation term premia. We also find a strongly positive relation between both real and nominal term premia and measures of dispersion in survey forecasts. Uncertainty about future exchange rates is a particularly important driver of variations in Brazilian term premia.

Color measurement using a smartphone applied to Madeira wines

Computer vision is a field that uses techniques to acquire, process, analyze and understand images from the real world in order to produce numeric or symbolic information in the form of decisions [1]. This project aims to use computer vision to prepare an app to analyze a Madeira Wine and characterize it (identify its variety) by its color. Dry or sweet wines, young or old wines have a specific color. It uses techniques to compare histograms in order to analyze the images taken from a test sample inside a special container designed for this purpose. The color analysis from a wine sample using an image captured by a smartphone can be difficult. Many factors affect the captured image such as, light conditions, the background of the sample container due to the many positions the photo can be taken (different to capture facing a white wall or facing the floor for example). Using new technologies such as 3D printing it was possible to create a prototype that aims to control the effect of those external factors on the captured image. The results for this experiment are good indicators for future works. Although it’s necessary to do more tests, the first tests had a success rate of 80% to 90% of correct results. This report documents the development of this project and all the techniques and steps required to execute the tests.

Geoprocessing applied to the assessment of environmental noise: a case study in the city of Sorocaba, São Paulo, Brazil

Noise mapping has been used as an instrument for assessment of environmental noise, helping to support decision making on urban planning. In Brazil, urban noise is not yet recognized as a major environmental problem by the government. Besides, cities that have databases to drive acoustic simulations, making use of advanced noise mapping systems, are rare. This study sought an alternative method of noise mapping through the use of geoprocessing, which is feasible for the Brazilian reality and for other developing countries. The area chosen for the study was the central zone of the city of Sorocaba, located in So Paulo State, Brazil. The proposed method was effective in the spatial evaluation of equivalent sound pressure level. The results showed an urban area with high noise levels that exceed the legal standard, posing a threat to the welfare of the population.
