Operational Strategies and Optimal Policies for the Diffusion of Environmental Energy Systems / Stratégies opérationnelles et politiques optimales pour la diffusion des systèmes énergétiques de l'environnement

Goodarzi, Shadi 19 April 2016 (has links)
L’objectif principal de cette thèse est d’étudier d’abord les problèmes potentiels qui peuvent entraver ou accélérer la diffusion des systèmes énergétiques environnementaux (par exemple, énergies renouvelables), puis l’impact de la pénétration de ces technologies dans le marché de l’énergie sur les équilibres du marché. À cette fin, nous observons le processus de diffusion à partir de différents points de vue tels que les décideurs, les fabricants, les clients et l’opérateur d’un système de transmission. Le premier chapitre de cette thèse fournit introduction et le contexte de la recherche. Le deuxième chapitre examine le rôle des décideurs et des fabricants technologiques sur la diffusion de ces technologies, alors que le troisième chapitre est consacré à l’étude de l’impact des différentes dimensions d’information sur la décision d’adopter une technologie environnementale tout au long du processus de telle adoption. Le chapitre quatre examine l’effet de l’entrée de ces technologies (énergies renouvelables) dans le marché d’électricité sur le prix au comptant d’électricité et sur le déséquilibre offre-demande. Enfin, le chapitre cinq conclut les résultats de cette étude et fournit des orientations pour des recherches futures. Les résultats présentés dans cette thèse offrent un aperçu de gestion précieux pour les décideurs, les fabricants de technologie et aux entreprises opérant dans le secteur de l'énergie. / The main goal of this dissertation is to study the potential factors that may hamper or accelerate the diffusion of environmental energy systems (e.g: renewable energies). To this end, using different methods such as game theory, survey data analysis, and time series data analysis we observe the diffusion of these technologies from different perspectives such as policy makers, manufacturers, and customers. This dissertation consists of five chapters. The first chapter provides introduction and background of the research. Second chapter investigates the role of policy makers and technology manufacturers on the diffusion of the environmental energy systems. Chapter three is dedicated to studying the impact of different information dimensions on the different stages of environmental technology adoption process. Chapter four examines effect of the penetration of the environmental energy systems into the electricity market by studying the electricity spot price and electricity supply- demand imbalance. Lastly, chapter five concludes the results of this study and provides directions for future researches. The results reported in this dissertation offer valuable managerial insights to policy makers, technology manufacturers and to firms operating in the energy sector.

Política fiscal e monetária ótimas em um modelo de médio porte para o Brasil pós plano real

Lobato, Carlos Eduardo January 2011 (has links)
Uma questão fundamental na macroeconomia é: Como um governo benevolente deveria conduzir as políticas monetária e fiscal no longo prazo e nos ciclos de negócios? Esta dissertação visa elucidar essa questão caracterizando as políticas monetária e fiscal ótimas para o Brasil no período pós Plano Real . Para tanto, será feito uso de um modelo de médio porte tal como proposto por Schmitt-Grohé e Uribe (2005). Médio porte, nada mais é do que a inclusão de quatro fontes de rigidez nominal: rigidez de preços, rigidez de salários, demanda por moeda por parte dos indivíduos e uma restrição cash-in-advance sobre a massa salarial das firmas. E cinco fontes de rigidez real: custos de ajustamento do investimento, utilização de capacidade variável, formação de hábitos, competição imperfeita nos mercados de produtos e fatores e taxação distorciva. Verificou-se que a estabilidade dos preços constitui essencialmente a política ótima. / A fundamental question in macroeconomics is how a benevolent government should conduct monetary and fiscal policies in the long-term and in the business cycles? This thesis aims to elucidate this question characterizing the optimal monetary and fiscal policies to Brazilin the period after the Real Plan. To do so, will be done using a medium-scale model as proposed by Schmitt-Grohé and Uribe (2005). Medium-scale, is nothing more than the inclusion of four sources of nominal rigidities: sticky prices, sticky wages, demand for money by individuals and a constraint cash-in-advance on the payroll of the firms. And five sources of real rigidities: investment adjustment costs, variable capacity utilization, habit formation, imperfect competition in product markets and factors and distorting taxation. It was found that price stability is essentially the optimal policy.
