Government transfers to individuals and families play a central role in the Brazilian social protection system, accounting for almost 14 per cent of GDP in 2009. While their fiscal and redistributive impacts have been widely studied, the macroeconomic effects of transfers are harder to ascertain. We constructed a Social Accounting Matrix (SAM) for 2009 and estimated short-term multipliers for seven different government monetary transfers . The SAM is a double-entry square matrix depicting all income flows in the economy. The data were compiled from the 2009 Brazilian National Accounts and the 2008/2009 POF, a household budget survey. Our SAM was disaggregated into 56 sectors, 110 commodities, 200 household groups and seven factors of production (capital plus six types of labor, according to schooling). Finally, we ran a set of regressions to separate household consumption into ‘autonomous’ (or ‘exogenous’) and ‘endogenous’ components. More specifically, we are interested in the effects of an exogenous injection into each of the seven government transfers outlined above. All the other accounts are thus endogenous. The so-called demand ‘leaks’ are income flows from the endogenous to exogenous accounts. Leaks—such as savings, taxes and imports—are crucial to determine the multiplier effect of an exogenous injection, as they allow the system to go back to equilibrium. The model assumes that supply is perfectly elastic to demand shocks. It assumes that the families’ propensity to save and consumption profile are fixed—that is, rising incomes do not provoke changes in behaviour. The multiplier effects of the on GDP corresponds to the growth in GDP resulting from each additional dollar injected into each transfer seven government transfers. If the government increased Bolsa Família expenditures by 1 per cent of GDP, overall economic activity would grow by 1.78 per cent, the highest effect. The Continuous Cash Benefit, comes second. Only three transfers— the private-sector and public servants’ pensions and FGTS withdrawals—had multipliers lower than unity. The multipliers for other relevant macroeconomic aggregates—household and total consumption, disposable income etc. —reveal a similar pattern. Thus, under the stringent assumptions of our model, we cannot reject the hypothesis that government transfers targeting poor households, such as the Bolsa Família, help foster economic expansion. Naturally, it should be stressed that the multipliers relate marginal injections into government transfers to short-term economic performance either real growth, or inflation if there is no idle capacity which is also useful to analyze. In the long term, there is no doubt that what truly matters is the growth of the country’s productive capacity.

Os depósitos sem vencimento são uma importante fonte de funding das instituições financeiras, e apresentam um desafio na gestão dos riscos de juros e liquidez, por não apresentarem um vencimento definido. Os depositantes podem sacar o montante de suas aplicações, bem como aportar novos volumes, a qualquer tempo sem a incidência de penalidades. Atualmente não há um modelo regulatório padronizado para mensurar o risco de juros desses produtos, bem como seu requerimento de capital. No entanto, novas regulamentações tem surgido com o intuito de, dentre outras coisas, trazer certa padronização para a modelagem dos depósitos sem vencimento, aumentando a comparabilidade do perfil de risco entre instituições financeiras. Essas regulamentações aumentam a necessidade de modelos quantitativos que definam um perfil de run-off da carteira ou de evolução dessa carteira no tempo. Este estudo tem como objetivo propor uma abordagem para modelar os fluxos de caixa esperados dos depósitos de poupança que possibilitará calcular o risco de mercado e apresentar sua aplicação dentro das novas normas de requerimento de capital que estão sendo propostas. Como resultado calculamos o risco de mercado e requerimento de capital para um balanço teórico.

O presente trabalho analisa o grau de sofisticação do Investidor Individual, subclasse da Categoria “Pessoa Física”, na negociação de produtos de renda variável no período compreendido entre Janeiro de 2006 e Dezembro de 2014. Através da análise de dados diários dos fluxos líquidos de investimentos, encontramos evidências que reforçam a hipótese de baixa sofisticação do Investidor Individual, no que diz respeito à diferença de atuação, de maneira agregada, entre ele e o investidor tido como mais qualificado (i.e., Investidor Estrangeiro), além de confirmarmos o ditado popular de que ele “Compra no Topo e Vende no Fundo”. Adicionalmente, encontramos evidência de causalidade entre, de um lado, a evolução do fluxo financeiro (tanto na compra quanto na venda), e do outro, variáveis como Retorno e Volatilidade, no sentido do primeiro causar estes. Os Testes de Causalidade de Granger e Impulso Resposta corroboram o indicado nas regressões; revela-se adicionalmente que um choque positivo na Volatilidade impacta negativamente as variáveis dependentes, de maneira crescente, por até 21 dias de pregão.

This dissertation uses an empirical gravity equation approach to study the relationship between nonreciprocal trade agreements (NRTAs) and members’ trade flows. Estimations relate bilateral imports to trade policy variables using a very comprehensive dataset with over fifty years of data. Results show that meager average trade effects exist only if members are excluded from the world trading system or if they are very poor. As trade flows between NRTA members are already rising before their creation, results also suggest a strong endogeneity concerning their formation. Moreover, estimations show that uncertainty and discretion tend to critically hinder NRTA’s performance. On the other hand, reciprocal trade agreements show the opposite pattern regardless of members’ income status.Encouraging developing countries’ openness to trade through reciprocal liberalization emerges consequently as a possible policy implication.

The purpose of this project is to understand, under a social constructionist approach, what are the meanings that external facilitators and organizational members (sponsors) working with dialogic methods place on themselves and their work. Dialogic methods, with the objective of engaging groups in flows of conversations to envisage and co-create their own future, are growing fast within organizations as a means to achieve collective change. Sharing constructionist ideas about the possibility of multiple realities and language as constitutive of such realities, dialogue has turned into a promising way for transformation, especially in a macro context of constant change and increasing complexity, where traditional structures, relationships and forms of work are questioned. Research on the topic has mostly focused on specific methods or applications, with few attempts to study it in a broader sense. Also, despite the fact that dialogic methods work on the assumption that realities are socially constructed, few studies approach the topic from a social constructionist perspective, as a research methodology per se. Thus, while most existing research aims at explaining whether or how particular methods meet particular results, my intention is to explore the meanings sustaining these new forms of organizational practice. Data was collected through semi-structured interviews with 25 people working with dialogic methods: 11 facilitators and 14 sponsors, from 8 different organizations in Brazil. Firstly, the research findings indicate several contextual elements that seem to sustain the choices for dialogic methods. Within this context, there does not seem to be a clear or specific demand for dialogic methods, but a set of different motivations, objectives and focuses, bringing about several contrasts in the way participants name, describe and explain their experiences with such methods, including tensions on power relations, knowledge creation, identity and communication. Secondly, some central ideas or images were identified within such contrasts, pointing at both directions: dialogic methods as opportunities for the creation of new organizational realities (with images of a ‘door’ or a ‘flow’, for instance, which suggest that dialogic methods may open up the access to other perspectives and the creation of new realities); and dialogic methods as new instrumental mechanisms that seem to reproduce the traditional and non-dialogical forms of work and relationship. The individualistic tradition and its tendency for rational schematism - pointed out by social constructionist scholars as strong traditions in our Western Culture - could be observed in some participants’ accounts with the image of dialogic methods as a ‘gym’, for instance, in which dialogical – and idealized –‘abilities’ could be taught and trained, turning dialogue into a tool, rather than a means for transformation. As a conclusion, I discuss what the implications of such taken-for-granted assumptions may be, and offer some insights into dialogue (and dialogic methods) as ‘the art of being together’.
