Life expectancy and human capital investment: the arrival of AIDS treatment in Brazil

This paper provides microevidence on the relationship between life expectancy and educational investment decisions. Human capital theory predicts an increase in life expectancy should lead to an augmenting in schooling investment. This paper uses an unique data set on AIDS patients among Brazilian inhabitants in an attempt to estimate the impact of the arrival of Antiretroviral therapy (ART) on educational outcomes. The availability of ART offsets the negative relationship between vertical HIV-transmission and schooling, around 68% and 57% for elementary and high school completion, respectively. Robustness tests indicate the results are not driven by convergence effects.

A Adoção das Estratégicas de CRM e a Fidelização do Cliente

As relações comerciais observadas no início do século passado se baseavam no atendimento personalizado, em que cada cliente era recebido pessoalmente pelo dono da loja, que por sua vez conhecia a clientela e suas principais necessidades. Com a massificação da produção e o surgimento dos grandes magazines e shopping centers, o foco das empresas se voltou para produtos e serviços, futor que promoveu o distanciamento das relações com os clientes, tornando-os ilustres desconhecidos para as empresas. Quase um século depois, o advento da Internet prOpICIOU um processo de reaproximação entre empresas e clientes, eis que as fronteiras geográficas começaram a desaparecer, as empresas locais começaram a atuar e concorrer mundialmente através da web, o mercado apresentou-se mais competitivo e os clientes conquistaram maior poder de escolha e se tornaram mais voláteis. Neste contexto de grandes massas, surge o CRM contemplando um conjunto de estratégias que permeiam toda a organização, como por exemplo, a revisão dos processos de negócios, a mudança da cultura com o foco no cliente, a automação dos serviços de marketing, vendas e atendimento, a disponibilização de multi-canais de contato com o cliente e a integração das bases de dados com os canais de interação. As estratégias de CRM, com base na revisão dos processos de negócios, na mudança da cultura organizacional e na infra-estrutura tecnológica, objetivam estabelecer relações individualizadas com uma imensa massa de clientes. Neste sentido, esse trabalho de pesquisa intenciona aprofundar os conhecimentos sobre influência do CRM na fidelização do cliente.

A importância de um índice de volatilidade para o mercado brasileiro

Este trabalho objetiva analisar a importância de um índice de volatilidade implícita para o mercado brasileiro. Por ser conhecida como uma medida das expectativas futuras dos investidores, diversos estudos, principalmente na literatura estrangeira, tem consegui extrair importantes informações quanto às mudanças na volatilidade implícita com a chegada de novos dados sobre a economia. Analisando as opções de juros (IDI) e de dólar, este trabalho verifica que informações de dados macroeconômicos impactam a volatilidade. Os resultados demonstram que as expectativas quanto ao mercado de juros são impactadas por diversos dados, porém o mesmo não acontece com o mercado de dólar, a qual se demonstrou ser impactada somente por intervenções do Banco Central via colocação de swaps. Por fim, o trabalho conclui que existem varáveis não transacionáveis que explicam as variações na volatilidade implícita, mostrando que as volatilidades implícitas das opções possuem bastantes informações quanto às expectativas.

A parturiente: um estudo psicológico

Este trabalho teve por objetivo identificar as vivências femininas no decorrer de seu primeiro parto normal. Pressupondo-se uma abordagem baseada nos ensinamentos fenomenológicos, foi planejada uma pesquisa exploratória de campo em que 30 puérperas de parto normal, poucas horas após terem dado à luz. As entrevistas seguiram o modelo metodológico da técnica de histórias de vida e, através destas, as puérperas contribuíram com um relato acerca de seu parto. Os relatos serviram para nos dar informes a respeito de quatro aspectos básicos acerca da parturiente no processar do seu parto normal: a) vivências físicas; b) vivências emocionais; c) significado da experiência e d) percepção da conduta médica. A experiência de gerar um filho para praticamente todas as mulheres entrevistadas mostrou-se altamente importante e plena de gratificações. Apenas um pequeno número de mulheres apresentou considerações negativas à chegada da criança.

Formation and destruction of coalition groups under economic growth

This paper introduces a model economy in which formation of coalition groups under technological progress is generated endogenously. The coalition formation depends crucially on the rate of arrival of new technologies. In the model, an agent working in the saroe technology for more than one period acquires skills, part of which is specific to this technology. These skills increase the agent productivity. In this case, if he has worked more than one period with the same technology he has incentives to construct a coalition to block the adoption of new technologies. Therefore, in every sector the workers have incentives to construct a coalition and to block the adoption of new technologies. They will block every time that a technology stay in use for more than one period.

Limited attention and investor disagreement: a nowcasting approach

When disagreement in economic models occurs due to different interpretations of public signals, the level of ``marketwide disagreement'' not necessarily decreases upon the arrival of a public signal. We propose an empirical assessment of this phenomenon. By using a measure of attention based on Google Trends, we show that an increase in the attention allocated by the market to a company is associated to a significant increase in disagreement about it.

Citizens and the future of multilateralism in a polycentric world at 2030: the perspectives of emerging countries for the trading system: the impasse of WTO, the trends of mega agreements, the logic of value chains and the advent of consumers concerns on international trade

A new paradigm is modeling the World: evolutionary innovations in all fronts, new information technologies, huge mobility of capital, use of risky financial tools, globalization of production, new emerging powers and the impact of consumer concerns on governmental policies. These phenomena are shaping the World and forcing the advent of a new World Order in the Multilateral Monetary, Financial, and Trading System. The effects of this new paradigm are also transforming global governance. The political and economic orders established after the World War and centered on the multilateral model of UN, IMF, World Bank, and the GATT, leaded by the developed countries, are facing significant challenges. The rise of China and emerging countries shifted the old model to a polycentric World, where the governance of these organizations are threatened by emerging countries demanding a bigger participation in the role and decision boards of these international bodies. As a consequence, multilateralism is being confronted by polycentrism. Negotiations for a more representative voting process and the pressure for new rules to cope with the new demands are paralyzing important decisions. This scenario is affecting seriously not only the Monetary and Financial Systems but also the Multilateral Trading System. International trade is facing some significant challenges: a serious deadlock to conclude the last round of the multilateral negotiation at the WTO, the fragmentation of trade rules by the multiplication of preferential and mega agreements, the arrival of a new model of global production and trade leaded by global value chains that is threatening the old trade order, and the imposition of new sets of regulations by private bodies commanded by transnationals to support global value chains and non-governmental organizations to reflect the concerns of consumers in the North based on their precautionary attitude about sustainability of products made in the World. The lack of any multilateral order in this new regulation is creating a big cacophony of rules and developing a new regulatory war of the Global North against the Global South. The objective of this paper is to explore how these challenges are affecting the Tradinge System and how it can evolve to manage these new trends.

WTO: challenges for the next 20

Coordenação e governança no Programa Territórios da Cidadania: uma análise multi-level a partir do Vale do Ribeira-SP

Poverty in Brazil has been gradually reduced. Among the main reasons, there are public policies for universalization of rights. On the other hand, the municipalities' Human Development Index indicates scenarios of growing inequality. In other words, some regions, basically of rural character, were left behind in that process of development. In 2008, the “Territórios da Cidadania” (Territories of Citizenship) Program was launched by the federal government, under high expectations. It was proposed to develop those regions and to prioritize the arrival of ongoing federal public policies where they were most demanded. The program has shown an innovative arrangement which included dozens of ministries and other federal agencies, state governments, municipalities and collegialities to the palliative management and control of the territory. In this structure, both new and existing jurisdictions came to support the program coordination. This arrangement was classified as an example of multi-level governance, whose theory has been an efficient instrument to understand the intra- and intergovernmental relations under which the program took place. The program lasted only three years. In Vale do Ribeira Territory – SP, few community leaderships acknowledge it, although not having further information about its actions and effects. Against this background, the approach of this research aims to study the program coordination and governance structure (from Vale Territory, considered as the most local level, until the federal government), based on the hypothesis that, beyond the local contingencies in Vale do Ribeira, the layout and implementation of the Territories of Citizenship Program as they were formulated possess fundamental structural issues that hinder its goals of reducing poverty and inequality through promoting the development of the territory. Complementing the research, its specific goal was to raise the program layout and background in order to understand how the relations, predicted or not in its structure, were formulated and how they were developed, with special attention to Vale do Ribeira-SP. Generally speaking, it was concluded that the coordination and governance arrangement of the Territories of Citizenship Program failed for not having developed qualified solutions to deal with the challenges of the federalist Brazilian structure, party politics, sectorized public actions, or even the territory contingencies and specificities. The complexity of the program, the poverty problem proposed to be faced, and the territorial strategy of development charged a high cost of coordination, which was not accomplished by the proposal of centralization in the federal government with internal decentralization of the coordination. As the presidency changed in 2011, the program could not present results that were able to justify the arguments for its continuation, therefore it was paralyzed, lost its priority status, and the resources previously invested were redirected.

O FUNDEB na prática: uma análise jurídica dos desafios para a implementação de políticas públicas no Brasil

Esta dissertação pretende examinar a estrutura jurídica (ponto de partida) do Fundo de Manutenção e Desenvolvimento da Educação Básica e de Valorização dos Profissionais da Educação (FUNDEB), que foi adotada com o intuito de promover a melhoria da educação por meio do financiamento entre entes federativos (ponto de chegada). Para tanto, utilizamos como arcabouço teórico a literatura de Direito e Desenvolvimento, que ressalta a relevância de desenhos jurídicos específicos apresentarem-se como instrumentos para assegurar o cumprimento de direitos fundamentais (SCHAPIRO e TRUBEK, 2012), o trabalho de Bucci sobre políticas públicas (BUCCI, 2006a, 2006b, 2013, 2015) e as discussões de Sen sobre desenvolvimento (SEN, 2000). Para aferir como o FUNDEB foi implementado pelo arcabouço institucional, utilizamos como recorte metodológico a análise dos diplomas normativos relativos a essa política e das decisões proferidas pelo Superior Tribunal de Justiça (STJ) e Supremo Tribunal Federal (STF), afetas ao cálculo e repasse dos recursos de complementação federal, que se destinam aos entes que não possuem condições de atender às determinações da Lei do Fundo. Mais precisamente, selecionamos decisões sobre o prazo para ajustar os valores de complementação federal e acerca da constitucionalidade da Lei do Piso do Magistério, que também exige complementação federal nos termos do FUNDEB. A partir das decisões, constatamos que as interpretações conferidas pelos órgãos judiciais permitiram maior discricionariedade à União para dispor sobre as regras para complementação federal, além de conceder maior prazo para proceder aos ajustes. Concluímos que as questões jurídicas apresentadas nas decisões evidenciam ambiguidades ou lacunas no desenho jurídico da política pública do FUNDEB, o que pode gerar certo grau de imprevisibilidade nas condições para sua implementação prática que podem, por sua vez, frustrar, parcial ou totalmente, os objetivos almejados pela política pública.

Flexible information acquisition and optimal Tobin tax in tractable dynamic global games

My dissertation focuses on dynamic aspects of coordination processes such as reversibility of early actions, option to delay decisions, and learning of the environment from the observation of other people’s actions. This study proposes the use of tractable dynamic global games where players privately and passively learn about their actions’ true payoffs and are able to adjust early investment decisions to the arrival of new information to investigate the consequences of the presence of liquidity shocks to the performance of a Tobin tax as a policy intended to foster coordination success (chapter 1), and the adequacy of the use of a Tobin tax in order to reduce an economy’s vulnerability to sudden stops (chapter 2). Then, it analyzes players’ incentive to acquire costly information in a sequential decision setting (chapter 3). In chapter 1, a continuum of foreign agents decide whether to enter or not in an investment project. A fraction λ of them are hit by liquidity restrictions in a second period and are forced to withdraw early investment or precluded from investing in the interim period, depending on the actions they chose in the first period. Players not affected by the liquidity shock are able to revise early decisions. Coordination success is increasing in the aggregate investment and decreasing in the aggregate volume of capital exit. Without liquidity shocks, aggregate investment is (in a pivotal contingency) invariant to frictions like a tax on short term capitals. In this case, a Tobin tax always increases success incidence. In the presence of liquidity shocks, this invariance result no longer holds in equilibrium. A Tobin tax becomes harmful to aggregate investment, which may reduces success incidence if the economy does not benefit enough from avoiding capital reversals. It is shown that the Tobin tax that maximizes the ex-ante probability of successfully coordinated investment is decreasing in the liquidity shock. Chapter 2 studies the effects of a Tobin tax in the same setting of the global game model proposed in chapter 1, with the exception that the liquidity shock is considered stochastic, i.e, there is also aggregate uncertainty about the extension of the liquidity restrictions. It identifies conditions under which, in the unique equilibrium of the model with low probability of liquidity shocks but large dry-ups, a Tobin tax is welfare improving, helping agents to coordinate on the good outcome. The model provides a rationale for a Tobin tax on economies that are prone to sudden stops. The optimal Tobin tax tends to be larger when capital reversals are more harmful and when the fraction of agents hit by liquidity shocks is smaller. Chapter 3 focuses on information acquisition in a sequential decision game with payoff complementar- ity and information externality. When information is cheap relatively to players’ incentive to coordinate actions, only the first player chooses to process information; the second player learns about the true payoff distribution from the observation of the first player’s decision and follows her action. Miscoordination requires that both players privately precess information, which tends to happen when it is expensive and the prior knowledge about the distribution of the payoffs has a large variance.
