It is difficult for policymakers to predict the behavior of people in response to a water rationing policy. The public may not necessarily behave as expected or in accordance with market rules or policy mandates. In this research, I will ask whether people were responsive to a summer 2011 City of Saskatoon legal restrictions to reduce their outdoor water consumption due to reduced capacity at the water treatment plant resulting from excessive solids in the river water. I will try to explore the policy response - which can be expressed as a reduction of outdoor water consumption in 2011 in response to the water mandate - while holding constant other factors, including environmental variables (temperature and rainfall), socio-economic factors (income and education level), lot size, and an annual downward trend in water consumption that appeared in many North American cities during the past two decades. Monthly water consumption data for the period from 2004 to 2012 for the City of Saskatoon were analyzed to detect if there is a policy response from the water mandate during June and July 2011. Regression analysis with water consumption as the dependent variable and lot size, temperature, rainfall, education index, income, consumption trend, and policy as independent variables was conducted to test whether there is a policy response in the Saskatoon water records, holding other factors relevant to water consumption constant. Results showed there was a statistically significant reduction in Saskatoon water consumption during June and July 2011 as a result of the water rationing mandate, with considerable variations through different neighborhoods. In addition, there is a positive relationship between water consumption and lot size and a reduction in water consumption over the research period from 2004 to 2012. The policy response varied widely across neighborhoods, and there was relationship between policy and annual income per capita, and household size; households with more income per capita are less responsive to the policy while bigger household sizes showed more policy responsiveness. Key words: City of Saskatoon, water rationing, water policy, water mandate, outdoor water use.

[pt] Esta dissertação investiga os efeitos do racionamento de energia elétrica ocorrido no período entre junho de 2001 a fevereiro de 2002, nas previsões de energia das principais concessionárias brasileiras. Para tal, estudamos o desempenho de modelos lineares e não-lineares. Dentre os modelos lineares, analisamos os modelos ARIMA (p,d,q) de Box & Jenkins e os modelos de amortecimento exponencial de Holt & Winters. Dentre os modelos não-lineares, são abordadas técnicas de inteligência artificial tais como Redes Neurais e Lógica Fuzzy. Visto que o racionamento levou a previsões ineficientes, propomos alternativas para reduzir seu impacto. Por último, investigamos os impactos causados pela crise energética nas previsões doze passos à frente de carga elétrica provenientes de vinte e oito concessionárias. A base de dados é composta pelos valores observados e as previsões fornecidas pelo PREVCAR, um dos sistemas de previsão da cadeia oficial de programas do setor elétrico brasileiro. Por meio de um procedimento de Análise de Agrupamento utilizando Redes Neurais Artificiais do tipo SOM (Self Organizing Map) de Kohonen são estabelecidos os grupos de concessionárias que possuem os mesmos comportamentos diante do racionamento. Como resultado final, foram estimados fatores de redução das previsões causados pelo racionamento, que servem como base de cálculo para reduções nas previsões futuras em períodos de crise de abastecimento. / [en] This dissertation aims at an exploratory study of impacts caused by the 2001 energy crisis on the current forecasts produced on a monthly basis for main distributing utilities. For that we show an accuracy study of the performance of the linear and non-linear models. It has been used, within the linear models class, the modeling approach of Box-Jenkins and exponential smoothing of Holt- Winters. Within the non-linear ones, it was chosen those based on artificial intelligence techniques, such as Fuzzy Logic and Artificial Neural Network. Due to the lack of accuracy of the models to cope with the discontinuities provoked by the crisis on the forecasts, some alternative tools to reduce the impact on the forecast errors are proposed. Finally, the impacts caused by the crisis on multiple steps ahead forecasts have also been investigated. It was taken the monthly forecasts produced by PREVCAR (one of official Brazilian load forecasting system), as well as the observed values covering the same period, to create the crisis response indices series for each one of the twenty and eight utilities included in the analysis. It was also used the well-known neural network based algorithm SOM (Self Organizing Maps) to classify the utilities into homogeneous groups, according to their response to the energy crisis. As a final result, for each group, it was estimated the reduction factors that can be used as a prior information in future energy supply crisis.

Studies are directed in order to raise awareness of the rational use of this natural asset that is essential to our survival. Only 0.007% of the water available in the world have easy access and can be consumed by humans, it can be found in rivers, lakes, etc... To better take advantage of the water used in homes and small businesses, reuse projects are often implemented, resulting in savings for customers of water utilities. The reuse projects involve several areas of engineering, like Environmental, Chemical, Electrical and Computer Engineering. The last two are responsible for the control of the process, which aims to make gray water (soapy water), and clear blue water (rain water), ideal for consumption, or for use in watering gardens, flushing, among others applications. Water has several features that should be taken into consideration when it comes to working its reuse. Some of the features are, turbidity, temperature, electrical conductivity and, pH. In this document there is a proposal to control the pH (potential Hydrogen) through a microcontroller, using the fuzzy logic as strategy of control. The controller was developed in the fuzzy toolbox of Matlab? / A cada dia a escassez de ?gua se torna um problema mais grave e que atinge diretamente a sociedade mundial.

O presente trabalho tem por objetivo analisar os modelos da firma bancária e crédito a partir de uma visão keynesiana. Inicialmente são apresentadas as proposições teóricas de Keynes e as derivações dessa a partir dos velhos e novos keynesianos. Na 2 parte os modelos representativos da firma bancária dessas escolas são descritos através de Tobin e Stiglitz, sendo neste último caso introduzido o conceito de assimetria de informação. No 3 capítulo é desenvolvida a abordagem pós-keynesiana de endogeneidade da oferta de moeda, sendo apresentados os modelos horizontalista de Moore, bem como as críticas da visão estruturalista, além do modelo de estratégia bancária de Alves, Dymski e Paula, desenvolvido a partir da hipótese de fragilidade financeira de Minsky. No capítulo 4 efetua-se uma discussão, feita por autores pós-keynesianos, sobre a possibilidade de compatibilizar em alguma medida o modelo de Tobin e o modelo de racionamento de crédito com a concepção pós-keynesiana de banco e crédito. / The present work aims at analyzing the models of the banking firm and credit from a Keynesian approach. Initially the theoretical proposals of Keynes and the Old and New Keynesian view of banking and credit are presented. In chapter 2 the representative models of the banking firm of these schools are described through Tobin and Stiglitzs model. In chapter 3 is developed the Post-Keynesian approach of money endogeneity - Moores banking firm model and the criticism made by the Post-Keynesian structuralist view. We also consider other Post Keynesian banking firm model, such as Dymskis model and Alves, Dymski and Paula banking strategy model. In chapter 4 we discuss if compatible the Post Keynesian approach is compatible or not with the conventional Keynesian theory of banking. In chapter 4 we consider the hypothesis of financial fragility of Minsky.

Introdução: A sepse é uma condição clínica de inflamação disseminada e descontrolada associada a um foco infeccioso. É uma condição de difícil estudo pela variedade de interações existentes entre as diversas instâncias do organismo e um conceito uniforme ainda está sendo debatido na literatura, o que dificulta a pesquisa e o estabelecimento de legislação que garanta fomento específico. Somado a isto, a exemplo de outras condições tempo-dependentes como infarto agudo do miocárdio, trauma e acidente vascular cerebral, a organização do fluxo do paciente através do sistema de saúde, garantindo leitos de terapia intensiva é fundamental. A U.E.- HCFMRP-USP é referência terciária para emergências para uma população de aproximadamente 4,5 milhões de habitantes e vem introduzindo mecanismos de gestão de fluxo como a priorização de leitos de terapia intensiva e desospitalização. Estas duas estratégias são recentes no Sistema Único de Saúde (SUS) e sua avaliação é fundamental para identificar o perfil de pacientes com Sepse e a importância da organização do sistema no prognóstico desta condição. Objetivos: 1) Avaliar a associação da priorização de Vagas em Terapia Intensiva com a mortalidade, morbidade e tempo de permanência hospitalar dos pacientes; 2) Avaliar o perfil epidemiológico dos pacientes com Sepse admitidos na U.E.-HCFMRP-USP; 3) Avaliar a estratégia de priorização de vagas no acesso de pacientes em sepse grave ou choque séptico aos leitos de terapia intensiva; 4) Avaliar a estratégia de transferência para leitos de retaguarda na oferta de leitos de terapia intensiva. 5) Avaliar a estratégia de priorização de vagas no retardo ao acesso de pacientes em sepse grave ou choque séptico aos leitos de terapia intensiva; 6) Avaliar a estratégia de priorização de vagas na mortalidade de pacientes em sepse grave ou choque séptico aos leitos de terapia intensiva; 7) Avaliar o índice prognóstico \"Quick\" SOFA nos pacientes com sepse grave ou choque séptico admitidos na U.E.-HCFMRP-USP. Metodologia: Trata-se de uma coorte retrospectiva realizada a partir de dados administrativos obtidos do sistema eletrônico de gerenciamento de pacientes da UEHCFMRP- USP de 01 janeiro de 2010 a 31 de dezembro de 20016. Foram construídas duas bases de dados. A primeira embasada em internação como identificador, na qual foram derivadas variáveis que representam priorização, dados demográficos, Comorbidade (Índice de Comorbidade de Charlson), a gravidade (\"Quick SOFA\"), linha de cuidado, presença de sepse e variáveis de desfecho. A segunda embasada em cada dia do período de estudo composta por variáveis sobre o número de leitos de CTI disponíveis, número de admissões, número de altas, número de transferências para hospital geral e para hospital de retaguarda. As variáveis quantitativas foram expressas como média e desvio-padrão ou mediana e mínimo e máximo de acordo com o teste de normalidade e as variáveis categóricas como percentagem. Para análise univariada foram utilizados testes t de Student, Análise de Variância ou equivalentes não-paramétricos, qui-quadrado ou teste exato de Fisher e \"Receiver Operating\'\' Curves\". Para a análise multivariada foram utilizadas a regressão logística multivariada com desfecho binário ou categórico conforme apropriado e a regressão multivariada de Poisson. A significância estatística foi expressa por p<0,05 ou a exclusão da unidade do intervalo de confiança. Resultados: 1) O processo de priorização de leitos de terapia intensiva se mostrou apropriado. Os pacientes que receberam prioridade maior para acesso ao CTI (prioridade 1- 5826;62,5%) eram mais jovens (55;12-100 - p<0,01), apresentavam menos comorbidades ( Charlson 0, 3583:61,5% - p<0,01) e menor gravidade (Quick\" SOFA\" 0,2170;37,2% - p<0,01; SOFA <10% - 1782;0,5% - p<0,01). Estes pacientes foram admitidos em maior proporção (2097;35,9% - p<0,01) e tiveram acesso mais rápido ao CTI (1081;52,5% - p<0,01), apresentando menor mortalidade (1853;31,8% - p<0,01). Ao se ajustar os possíveis fatores de confusão para estabelecer a razão de chances de receber prioridade 1 pelo intensivista, maior valor da classe de Charlson (Comorbidade) - OR 0,53; 0,49-0,57, do \"Quick SOFA\" (Gravidade) - OR 0,45; 0,43- 0,48 e a presença da condição Sepse - OR 0,20-0,17;0,23 estiveram associados independentemente à menor chance de receber esta classificação. 2) Os pacientes sépticos identificados neste estudo tinham maior idade (61;12-97 - p<0,01), maior prevalência do gênero masculino (646;56,2% - p<0,01) , menor amparo social (714;61,8% - p=0,048), maior índice de Comorbidade (Charlson 2 - 222;19,3% - p<0,01) e de Gravidade (SOFA >90% - 152;13,2% - p<0,01), apresentaram maior mortalidade intrahospitalar (838;73% - p<0,01), maior retardo para admissão no CTI e maior duração da internação hospitalar (7,3;0-304 - p<0,01). Quando comparados com outras linhas de cuidado bem estabelecidas, observou-se que a Sepse pode ser equiparada com o Trauma em termos de incidência (sepse 1148;22,5% - p<0,01; trauma 1138;22,3% - p<0,01), sendo inferior apenas às Síndromes Coronarianas Agudas (SCA)(1972;38,7% - p<0,01). Na análise multivariada, a Sepse está associada à menor chance de receber prioridade 1(0,2 ; IC 95% - 0,17;0,23) independente de outros fatores de confusão, persistiu como fator independente para mortalidade intra-hospitalar total (2,7; IC 95% - 2,32;3,17) e para a mortalidade de pacientes admitidos no CTI (2,38; IC 95% - 1,82;3,11). 3) A priorização de vagas facilitou o acesso dos pacientes ao CTI; 4) A estratégia de transferência de pacientes de alta dependência que deixaram de requerer recursos de alta complexidade se mostrou importante para o sistema. As três instituições parceiras não se distinguiram com relação ao índice de Comorbidade de Charlson (Altinópolis , Charlson 0, 25;28,1%, Charlson 1, 29;32,6%, Charlson 2, 35;39,3%; Guariba Charlson 0, 60;35,7%, Charlson 1, 50;29,7%, Charlson 2, 58;34,5%; São Simão, Charlson 0, 20;28,5%, Charlson 1, 17;24,3%, Charlson 2, 33;47,2% - p=0,894) e tiveram desempenho semelhante com relação à mortalidade(Altinópolis 35;39,33%, Guariba 78;46,4%, São Simão 33;47,1% - p=0,26) e alta domiciliar (Altinópolis 37;41,5%; Guariba 60;35,71%, São Simão 19;27,1% - p=0,26). Os pacientes com problemas neurológicos foram responsáveis pela maioria das transferências (Altinópolis 61;68,5%, Guariba 92;54,7%, São Simão 40;57,1% - p=0,06). Ao longo dos anos, houve melhora do desempenho das instituições com relação à mortalidade (2013,16 óbitos;44,4%, 2016, 37 óbitos;35,2% - p<0,01) e a relação de permanência na U.E.-HCFMRP-USP comparada à permanência total (soma da internação na U.E.- HCFMRP-USP e da internação nos leitos de longa permanência) decresceu (2013, 67,8 dias;0-97,7, 2016, 58,87 dias;0-100 - p=0,005). Na análise multivariada, observou-se que a transferência para leitos de longa permanência foi fator independente em aumentar a disponibilidade de leitosde CTI na U.E.-HCFMRP-USP (com o ano de 2016 1,54; IC 95% - 1,18-2,01, excluindo-se o ano de 2016 1,73; IC 95% - 1,26;2,39). 5) Não houve retardo de admissão no CTI dos pacientes sépticos que receberam prioridade 1 quando se ajustou por possíveis fatores de confusão (0,43; IC 95% - 0,35;0,53); 6) O índice prognóstico \"Quick\" SOFA teve baixa acurácia nos pacientes com sepse grave ou choque séptico admitidos na U.E.-HCFMRPUSP (AUROC= 0,5646, IC95% - 0,52991;0,59930-p<0,001). Conclusões: A Sepse apresentou elevada mortalidade mesmo quando foi garantida a admissão ao CTI em comparação com outros estudos, o que pode refletir o viés de seleção da Regulação Médica. As estratégias de gerenciamento de fluxo foram eficazes em garantir acesso e aumentar a disponibilidade de leitos. / Introduction: Sepsis is a clinical condition of disseminated and uncontrolled inflammation associated with an infectious outbreak. It is a condition difficult to study because of the variety of interactions between the various organs of the organism and lack of a uniform concept in the literature, which makes it difficult to research and establish legislation that guarantees specific promotion. Added to this, like other timedependent conditions such as acute myocardial infarction, trauma and stroke, the organization of patient flow through the health system, ensuring intensive care beds is critical. The U.E.-HCFMRP-USP is a tertiary reference for emergencies for a population of approximately 4.5 million inhabitants and has been introducing flow management mechanisms such as the prioritization of intensive care and de-hospitalization beds. These two strategies are recent in the Unified Health System (SUS) and their valuation is fundamental to identify the profile of patients with Sepsis and the importance of the organization of the system in the prognosis of this condition. Objectives: 1) To evaluate the association of the prioritization of Vacancies in Intensive Care with the mortality, morbidity and hospital stay time of the patients; 2) To evaluate the epidemiological profile of patients with sepsis admitted to U.E.-HCFMRP-USP; 3) Evaluate the strategy of prioritizing vacancies in the access of patients in severe sepsis or septic shock to intensive care beds; 4) Evaluate the transfer strategy for back beds in the offer of intensive care beds. 5) Evaluate the strategy of prioritization of vacancies in the delay to access of patients in severe sepsis or septic shock to intensive care beds; 6) To evaluate the strategy of prioritization of vacancies in the mortality of patients in severe sepsis or septic shock to intensive care beds; 7) To evaluate the \"Quick\" SOFA prognostic index in patients with severe sepsis or septic shock admitted to U.E.- HCFMRP-USP. Methodology: This is a retrospective cohort based on administrative data obtained from the electronic patient management system of the EU-HCFMRP-USP from January 01, 2010 to December 31, 20016. Two databases were constructed. The first was based on admission as an identifier, in which variables were derived, such as prioritization, demographic data, Comorbidity (Charlson Comorbidity Index), severity (\"Quick SOFA\"), clinical pathway, presence of sepsis and outcome variables. The second, based on each day of the study period, contains variables on the number of CTI beds available, number of admissions, number of discharges, number of transfers to general hospital and back hospital. We expressed quantitative variables as mean and standard deviation or median and minimum and maximum according to the normality test and categorical variables as percentage. We used Student t tests, Analysis of Variance or non-parametric equivalents, chi-square or Fisher\'s exact test and \"Receiver Operating Curves\" for univariate analysis. We used Multivariate logistic regression with binary or categorical outcome and multivariate Poisson regression as appropriate for the multivariate analysis. A p <0.05 or the exclusion of the unit from the confidence interval signaled statistical significance. Results: 1) The process of prioritizing intensive care beds was appropriate. Patients who received higher priority for CTI access (priority 1 - 5826;62,5%) were younger (55;12- 100 - p<0,01), had less comorbidities ( Charlson 0, 3583;61,5%, p<0,01) and less severity (Quick\" SOFA\" 0,2170;37,2% - p<0,01; SOFA <10% - 1782;0,5% - p<0,01). These patients were admitted in greater proportion (2097;35,9% - p<0,01) and had faster access to ICU (1081;52,5% - p<0,01), presenting lower mortality (1853;31,8% - p<0,01). When adjusting the possible confounding factors to establish the odds ratio to receive priority 1 by the intensivist, higher value of the Charlson class OR 0,53; 0,49-0,57, the \"Quick SOFA\" (Severity) - OR 0,45; 0,43-0,48 and the presence of Sepsis condition - OR 0,20-0,17;0,23 were independently associated with a lower chance of being classified as priority 1. 2) The septic patients identified in this study had older age (61;12- 97 - p<0,01), higher prevalence of male gender (646;56,2% - p<0,01), lower social protection (714;61,8% - p=0,048), higher Comorbidity (Charlson 2 - 222;19,3% - p<0,01) and Severity index (SOFA >90% - 152;13,2% - p<0,01), higher in-hospital mortality (838;73% - p<0,01), longer ICU admission delay and longer hospital stay(7,3;0-304 - p<0,01). When compared to other clinical pathways, it was observed that Sepsis can be equated with Trauma in terms of incidence (sepsis 1148;22,5% - p<0,01; trauma 1138;22,3% - p<0,01), being inferior only to Acute Coronary Syndromes (ACS) (1972;38,7% - p<0,01). In the multivariate analysis, Sepsis was more associated to lower chance of receiving priority 1(0,2; IC 95% - 0,17;0,23) independent of other confounding factors, it persisted as an independent factor for total in-hospital mortality(2,7; IC 95% - 2,32;3,17) and for the mortality of patients admitted to the ICU(2,38; IC 95% - 1,82;3,11). 3) The prioritization of vacancies facilitated the access of the septic patients to the ICU. 4) The strategy of transference of patients of high dependence that stopped requesting resources of high complexity proved to be important for the system. The three partner institutions did not differ in relation to the Charlson Comorbidity Index (Altinópolis , Charlson 0, 25;28,1%, Charlson 1, 29;32,6%, Charlson 2, 35;39,3%; Guariba Charlson 0, 60;35,7%, Charlson 1, 50;29,7%, Charlson 2, 58;34,5%; São Simão, Charlson 0, 20;28,5%, Charlson 1, 17;24,3%, Charlson 2, 33;47,2% - p=0,894) and had a similar performance in relation to mortality (Altinópolis 35;39,33%, Guariba 78;46,4%, São Simão 33;47,1% - p=0,26) and household discharge (Altinópolis 37;41,5%; Guariba 60;35,71%, São Simão 19;27,1% - p=0,26). Patients with neurological problems were responsible for most of the transfers (Altinópolis 61;68,5%, Guariba 92;54,7%, São Simão 40;57,1% - p=0,06). Over the years, there has been an improvement in the institutions\' performance in relation to mortality (2013,16 deaths;44,4%, 2016, 37 deaths;35,2% - p<0,01) and the length of stay in the EUHCFMRP- USP compared to the total stay (sum of hospitalization in the EU-HCFMRP-USP and length of stay in long-stay beds) decreased (2013, 67,8 days;0-97,7, 2016, 58,87 days;0-100 - p=0,005).In the multivariate analysis, we observed that the transfer to long-stay beds was an independent factor in increasing the availability of ICU beds in U.E.-HCFMRPUSP (with year 2016 1,54; IC - 95% 1,18;2,01, without year 2016 1,73; IC - 95% 1,26;2,39). 5) There was no delay in ICU admission for septic patients who received priority 1 when adjusted for possible confounding factors (0,43; IC 95% - 0,35;0,53).7) The \"Quick\" SOFA prognostic index had low accuracy in patients with severe sepsis or septic shock admitted to U.E.-HCFMRP-USP (AUROC= 0,5646, IC95% - 0,52991;0,59930 - p<0,001).Conclusions: Sepsis presented a high mortality even when admission to the ICU was guaranteed in comparison to other studies, which may reflect the selection bias of the Medical Regulation. Flow management strategies were effective in securing access and increasing bed availability.

Neste estudo, a rede elétrica é utilizada como instrumento de análise para a integração territorial restrita da cidade de Tefé ao meio técnico-científico-informacional. A ocorrência de interrupções e racionamentos no fornecimento de energia elétrica na cidade, localizada no interior do estado do Amazonas, proporciona prejuízos econômicos, sociais e culturais significativos à população, dificultando seu pleno desenvolvimento. Dessa forma, o conhecimento dos principais eventos da evolução histórica da rede elétrica no território nacional e das políticas de planejamento governamental que corroboraram para o surgimento deste problema é analisado com o propósito de entender as dinâmicas socioespaciais que não facilitam a inserção dessa fração do território ao meio geográfico contemporâneo. Os projetos de integração na fronteira amazônica produziram um crescimento sem planejamento dos objetos técnicos, que, estruturados às pressas, proporcionaram obras imediatistas, realizadas em curto prazo -- o que Milton Santos (1994) chama, para os países subdesenvolvidos, de -saltar etapas?. Isso propiciou à população consequências negativas vinculadas às estruturas sociotécnicas amazônicas, que não atendem integralmente às funções que deveriam realizar, como é o caso da rede elétrica do Amazonas. A realização de uma análise de eventos, projetos e propostas que permitem sugestionar uma mitigação ou solução para esse obstáculo ao exercício do direito à cidadania do tefeense é direcionada nesta pesquisa. / In this study, the grid is used as an analytical tool for the restricted territorial integration in the city of Tefé to the technical and scientific-informational mean. The occurrence of interruptions and shortages in the electricity supply in the city, located within the State of Amazonas, provides significant economic, social and cultural losses to the population, hindering their full development. Thus, the knowledge of the main events of the historical evolution for the electric grid in the country and the government planning policies which confirmed to the emergence of this problem is analyzed in order to understand the socio-spatial dynamics that do not facilitate the insertion of this fraction in the contemporary geographical territory. Integration projects in the Amazon frontier produced an unplanned growth of technical objects, which were structured hastily, providing immediately works made in the short term, which according to Milton Santos (1994) is named by -leap-frog? in developing countries. With that, the population is linked to negative consequences related to the Amazonians socio-technical structures that do not match the functions they should undertake such as Amazon electricity grid. Performing an analysis of the events, projects and proposals allow us to suggest a mitigation or a solution to this obstacle that is related to the exercise of the tefeense citizenship right.

In the first part of the thesis I focus on credit markets in developing countries, and describe the competitive interaction between Microfinance Institutions (MFIs). <p>Microfinance has recently attracted a lot of attention from investors, politicians, scholars and, most of all, people working on development. As a results, a huge number of MFIs are being created all over the world so that, as of today, practitioners reckon that about 100 millions of customers are being served. Remarkably, about 67% of them are women. <p><p>The reason of this extraordinary effort is that Microfinance is considered the most promising development tool currently available. This belief is based on two important features of Microfinance: (i) It promises to be financially viable (and in some cases even profitable) since poor people have proven to be reliable clients. As a result, Microfinance is potentially a zero-cost development tool. (ii) It hinges on the entrepreneurial abilities of the poor. It is designed to help the poor to help themselves, in their own home countries, by allowing them to use their skills, ideas and potentials. This should progressively make developing countries independent of rich ones' help. <p><p>The growth of Microfinance has been so fast that many issues and related research questions are still not answered. In my thesis I try to address one of them, that I believe particularly important: the increase of competition between MFIs. As economic theory predicts, competition can have dramatic consequences in terms of borrower welfare, profitability of the institutions and, therefore, on the attractiveness of the business for potential investors, donors and entrants. I use the tools of industrial organization and contract theory to understand these effects, measure them, and give some interesting policy advice. <p><p>In the first paper, I analyze the effects of entry of a new MFI in a previously monopolistic microcredit market. In order to catch the salient features of financial markets in developing countries, I use a model of asymmetric information and assume that institutions can offer only one type of contract. I consider different behavioral assumptions for the MFIs and study their influence on equilibrium predictions. The model allows showing that competition can lead to equilibria in which MFIs differentiate their contracts in order to screen borrowers. This process can, unfortunately, make the poor borrowers worse off. Interestingly, the screening process we describe creates a previously unexplored source of credit rationing. I also prove that the presence in the market of an altruistic MFI, reduces rationing and, via this channel, affects positively the competitor's profit.<p><p>In the second paper, I study the effects of competition in those markets in which, due to the absence of credit bureaus, small entrepreneurs can simultaneously borrow from more than one institution. As in the first paper, I analyze an oligopolistic microcredit market characterized by asymmetric information and institutions that can offer only one type of contract. The main contribution is to show that appropriate contract design can eliminate the ex-ante incentives for multiple borrowing. Moreover, when the market is still largely unserved and particularly risky, a screening strategy leading to con- <p>tract differentiation and credit rationing is unambiguously the most effective to avoid multiple borrowing. The result of this paper can also be read as important robustness checks of the findings of my first paper. <p><p>In the last part of the thesis, I depart from the analysis of developing countries to consider, more generally, the corporate governance of financial infrastructures. The efficient functioning of financial markets relies more and more on the presence of infrastructures providing services like clearing, settlement, messaging and many others. The last years have been characterized by interesting dynamics in the ownership regime of these service providers. Both mutualizations and de-mutualizations took place, together with entry and exit of different players. <p><p>Starting from this observation, in the last paper (with Joachim Keller), we analyze the effects of competitive interaction between differently owned financial providers. We mainly focus on the incentives to invest in safety enhancing measures and we describe the different equilibrium market configurations. We use a model in which agents need an input service for the financial market they operate in. They can decide whether to provide it them selves by forming a Cooperative or outsource it from a Third Party Provider. We prove that the co-existence of differently governed infrastructures leads to a significant reduction in the investment in safety. In most cases, monopolistic provision is preferable to competition. Moreover, the decision rule used within the Cooperative plays a central role in determining the optimal market configuration. <p><p>All in all, throughout my thesis, I use the tools of industrial organization and contract theory to model the competitive interaction of the different actors operating in financial markets. Understanding the dynamics typical of developing countries can help in gaining a deeper comprehension of the markets in richer countries, and vice-versa. I am convinced that analyzing the differences and the similarities of financial markets in different regions of the world can be of great importance for economic theorists, in that it provides a counterfactual for the assumptions and the results on which our predictions and policy advices are based.<p> / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

This thesis explores the origin of one of the most engrossing concerns of the post-colonial Indian state, that is, its extensive, intricate, and expensive feeding arrangements for the civilians. It tracks the colonial origin of the post-colonial welfare state, of which state-management of food is one of the most publicized manifestations. This thesis examines the intervention of the late colonial British state in food procurement and distribution in India during the Second World War, and various forms of such intervention, such as the introduction of food rationing and food austerity laws. It argues that the war necessitated actions on the part of the colonial state to secure food supplies to a vastly expanded British Indian Army, to the foreign Allied troops stationed in India, and to the workers employed in war-industries. The thesis brings forth the constitutional and political predicaments that deprived the colonial central government's food administration of success. It further reveals how the bitter bargaining about food imports into India between the Government of India and the War Cabinet in Britain hampered the state efforts to tackle the food crisis. By discussing the religious and cultural codes vis-à-vis food consumption that influenced government food policies, this thesis has situated food in the historiography of consumption in colonial India. In addition to adopting a political approach to study food, it has also applied sociological treatment, particularly while dealing with how the wartime scarcity, and consequent austerity laws, forced people to accept novel consumption cultures. It also contributes to the historiography of 'everyday state'. Through its wartime intervention in everyday food affairs, the colonial state that had been distant and abstract in the perception of most common households, suddenly became a reality to be dealt with in everyday life within the domestic site. Thus, the macro state penetrated micro levels of existence. The colonial state now even developed elaborate food surveillance to gather intelligence about violation of food laws. This thesis unravels the responses of some of the political and religious organizations to state intervention in quotidian food consumption. Following in this vein, through a study of the political use of famine-relief in wartime Bengal, it introduces a new site to the study of communal politics in India, namely, propagation of Hindu communal politics through distribution of food by the Hindu Mahasabha party. Further, it demonstrates how the Muslim League government's failure to prevent the Great Bengal Famine of 1943-44 was politically used by the Mahasabha to oppose the League's emerging demand for the creation of Pakistan.

É proposta uma nova categoria: bens de rivalidade extrema (RE) para adequada classificação da eletricidade. A RE se manifesta quando o consumidor marginal demanda do sistema a última unidade de eletricidade disponível na rede o que implica no completo desligamento do sistema, mesmo que essa unidade não disponível seja infinitesimal em relação à capacidade plena, o que é uma característica única. Governos coordenam investimentos em capacidade excedente para lidar com esse fenômeno, porém essa tal capacidade extra prejudica a concorrência, a inovação e investimentos em eficiência energética e fontes alternativas. O Gerenciamento da Rivalidade Extrema (GRE) propõe tratar de maneira diferente o fenômeno da RE através de capacidades de rede inteligente para promover de maneira individualizada e organizada a desconexão de consumidores quando ocorrem situações críticas de suprimento, seguindo uma ordem que desconecta prioritariamente os consumidores menos sensíveis a interrupções. A política de Valor de Segurança do Suprimento (VSS) se baseia em declarações dos consumidores a respeito de quanto estão dispostos a pagar em eventos críticos para evitar serem desconectados. Essa política inicia desconexões individualizadas de consumidores que declararam VSS = 0 procedendo em ordem crescente de valores de VSS até que seja equilibrada a demanda e a oferta e assegurado o equilíbrio do sistema. Todos consumidores que forem preservados devem pagar o VSS declarado, cuja receita pode ser usada para remunerar consumidores que foram desconectados ou financiar investimentos em expansão de capacidade / Abstract: Economic goods are classified as rival, non-rival and anti-rivals goods. We propose a new category: extreme rivalry goods (ER) for proper classification of electricity. ER manifests itself when the marginal consumer demands the last unit of electricity available on the grid implying in a complete shutdown of the system, even though by an infinitesimal amount compared to the total capacity, which is a unique feature. Governments coordinate investments in overcapacity to deal with this with the downside of preventing competition, innovation and undermining investments in energy efficiency and alternative energy. Management of Extreme Rivalry (MER) uses a different approach to ER relying in smart grid features to promote individualized and ordered disconnection of consumers when there is a critical supply situation, following a queue that begins with consumers less sensitive to disconnections. A policy of "Value of Supply Maintenance" (VSM) is based on declarations from consumers about how much they are willing to pay during critical supply events to prevent being disconnected. The VSM method begins disconnecting consumers who informed VSM = 0 proceeding in order of increasing VSM values until the balance between generation and consumption is ensured to balance the system. All preserved consumers must pay the VSM / Doutorado / Eletrônica, Microeletrônica e Optoeletrônica / Doutor em Engenharia Elétrica
