Microinsurance: income risk, social security and the demand for private onsurance by low-income families

Insurance provision against uncertainties is present in several dimensions of peoples´s lives, such as the provisions related to, inter alia, unemployment, diseases, accidents, robbery and death. Microinsurance improves the ability of low-income individuals to cope with these risks. Brazil has a fairly developed financial system but still not geared towards the poor, especially in what concerns the insurance industry. The evaluation of the microinsurance effects on well-being, and the demand for different types of microinsurance require an analysis of the dynamics of the individual income process and an assessment of substitutes and complementary institutions that condition their respective financial behavior. The evaluation of the microinsurance effects on well-being, and the demand for different types of microinsurance require an analysis of the dynamics of the individual income process and an assessment of substitutes and complementary institutions that condition their respective financial behavior. The Brazilian government provides a relatively developed social security system considering other countries of similar income level which crowds-out the demand for insurance and savings. On the other hand, this same public infrastructure may help to foster microfinance products supply. The objective of this paper is to analyze the demand for different types of private insurance by the low-income population using microdata from a National Expenditure Survey (POF/IBGE). The final objective is to help to understand the trade-offs faced for the development of an emerging industry of microinsurance in Brazil.

The state of the youth: prisons, drugs and car crashes

By virtue of the volume and nature of their attributions, including secondary school as well as problem-areas such as security and traffic, the Brazilian states are the ultimate responsible entities for young people. This study argues in favour of granting greater freedom for the states to define their own public policy parameters to deal with local features and to increase the degree of learning about such actions at the national level. In empirical terms, the study assesses the impacts of new laws, such as the new traffic code (from the joint work with Leandro Kume, EPGE/FGV doctor’s degree student) and traces the statistics for specific questions like drugs, violence and car accidents. The findings show that these questions produce different results for young men and women.The main characters in these dramas are young single males, suggesting the need for more distinguished public policies according not only to age, but also by gender. The study also reveals that the magnitude of these problems changes according to the youth’s social class. Prisons concern poorer men (except for the functional illiterate) while fatal car accidents and the confessed use of drugs concern upper-class boys.

Essays in taxation and savings

Esta tese é composta por três artigos. Dois deles investigam assuntos afeitos a tributação e o terceiro é um artigo sobre o tema “poupança”'. Embora os objetos de análise sejam distintos, os três possuem como característica comum a aplicação de técnicas de econometria de dados em painel a bases de dados inéditas. Em dois dos artigos, utiliza-se estimação por GMM em modelos dinâmicos. Por sua vez, o artigo remanescente é uma aplicação de modelos de variável dependente latente. Abaixo, apresenta-se um breve resumo de cada artigo, começando pelos dois artigos de tributação, que dividem uma seção comum sobre o ICMS (o imposto estadual sobre valor adicionado) e terminando com o artigo sobre poupança. O primeiro artigo analisa a importância da fiscalização como instrumento para deter a evasão de tributos e aumentar a receita tributária, no caso de um imposto sobre valor adicionado, no contexto de um país em desenvolvimento. O estudo é realizado com dados do estado de São Paulo. Para tratar questões relativas a endogeneidade e inércia na série de receita tributária, empregam-se técnicas de painel dinâmico. Utiliza-se como variáveis de controle o nível do PIB regional e duas proxies para esforço fiscal: a quantidade e o valor das multas tributárias. Os resultados apontam impacto significativo do esforço fiscal nas receitas tributárias. O artigo evidencia, indiretamente, a forma como a evasão fiscal é afetada pela penalidade aplicada aos casos de sonegação. Suas conclusões também são relevantes no contexto das discussões sobre o federalismo fiscal brasileiro, especialmente no caso de uma reforma tributária potencial. O segundo artigo examina uma das principais tarefas das administrações tributárias: a escolha periódica de contribuintes para auditoria. A melhora na eficiência dos mecanismos de seleção de empresas tem o potencial de impactar positivamente a probabilidade de detecção de fraudes fiscais, provendo melhor alocação dos escassos recursos fiscais. Neste artigo, tentamos desenvolver este mecanismo calculando a probabilidade de sonegação associada a cada contribuinte. Isto é feito, no universo restrito de empresas auditadas, por meio da combinação “ótima” de diversos indicadores fiscais existentes e de informações dos resultados dos procedimentos de auditoria, em modelos de variável dependente latente. Após calculados os coeficientes, a probabilidade de sonegação é calculada para todo o universo de contribuintes. O método foi empregado em um painel com micro-dados de empresas sujeitas ao recolhimento de ICMS no âmbito da Delegacia Tributária de Guarulhos, no estado de São Paulo. O terceiro artigo analisa as baixas taxas de poupança dos países latino-americanos nas últimas décadas. Utilizando técnicas de dados em painel, identificam-se os determinantes da taxa de poupança. Em seguida, faz-se uma análise contrafactual usando a China, que tem apresentado altas taxas de poupança no mesmo período, como parâmetro. Atenção especial é dispensada ao Brasil, que tem ficado muito atrás dos seus pares no grupo dos BRICs neste quesito. O artigo contribui para a literatura existente em vários sentidos: emprega duas amplas bases de dados para analisar a influência de uma grande variedade de determinantes da taxa de poupança, incluindo variáveis demográficas e de previdência social; confirma resultados previamente encontrados na literatura, com a robustez conferida por bases de dados mais ricas; para alguns países latino-americanos, revela que as suas taxas de poupança tenderiam a aumentar se eles tivessem um comportamento mais semelhante ao da China em outras áreas, mas o incremento não seria tão dramático.

International civil society actors in Genetically Modificied Organisms as a field of struggle: a neo-gramscian study in Brazil and the United Kingdom

Since the international financial and food crisis that started in 2008, strong emphasis has been made on the importance of Genetically Modified Organisms (GMOs) (or “transgenics”) under the claim that they could contribute to increase food productivity at a global level, as the world population is predicted to reach 9.1 billion in the year 2050 and food demand is predicted to increase by as much as 50% by 2030. GMOs are now at the forefront of the debates and struggles of different actors. Within civil society actors, it is possible to observe multiple, and sometime, conflicting roles. The role of international social movements and international NGOs in the GMO field of struggle is increasingly relevant. However, while many of these international civil society actors oppose this type of technological developments (alleging, for instance, environmental, health and even social harms), others have been reportedly cooperating with multinational corporations, retailers, and the biotechnology industry to promote GMOs. In this thesis research, I focus on analysing the role of “international civil society” in the GMO field of struggle by asking: “what are the organizing strategies of international civil society actors, such as NGOs and social movements, in GMO governance as a field of struggle?” To do so, I adopt a neo-Gramscian discourse approach based on the studies of Laclau and Mouffe. This theoretical approach affirms that in a particular hegemonic regime there are contingent alliances and forces that overpass the spheres of the state and the economy, while civil society actors can be seen as a “glue” to the way hegemony functions. Civil society is then the site where hegemony is consented, reproduced, sustained, channelled, but also where counter-hegemonic and emancipatory forces can emerge. Considering the importance of civil society actors in the construction of hegemony, I also discuss some important theories around them. The research combines, on the one hand, 36 in-depth interviews with a range of key civil society actors and scientists representing the GMO field of struggle in Brazil (19) and the UK (17), and, on the other hand, direct observations of two events: Rio+20 in Rio de Janeiro in 2012, and the first March Against Monsanto in London in 2013. A brief overview of the GMO field of struggle, from its beginning and especially focusing in the 1990s when the process of hegemonic formation became clearer, serves as the basis to map who are the main actors in this field, how resource mobilization works, how political opportunities (“historical contingencies”) are discovered and exploited, which are the main discourses (“science” and “sustainability” - articulated by “biodiversity preservation”, “food security” and “ecological agriculture”) articulated among the actors to construct a collective identity in order to attract new potential allies around “GMOs” (“nodal point”), and which are the institutions and international regulations within these processes that enable hegemony to emerge in meaningful and durable hegemonic links. This mapping indicates that that the main strategies applied by the international civil society actors are influenced by two central historical contingencies in the GMO field of struggle: 1) First Multi-stakeholder Historical Contingency; and 2) “Supposed” Hegemony Stability. These two types of historical contingency in the GMO field of struggle encompass deeper hegemonic articulations and, because of that, they induce international civil society actors to rethink the way they articulate and position themselves within the field. Therefore, depending on one of those moments, they will apply one specific strategy of discourse articulation, such as: introducing a new discourse in hegemony articulation to capture the attention of the public and of institutions; endorsing new plural demands; increasing collective visibility; facilitating material articulations; sharing a common enemy identity; or spreading new ideological elements among the actors in the field of struggle.
