The Bayesian Foundations of solution concepts of games

We transform a non co-operati ve game into a -Bayesian decision problem for each player where the uncertainty faced by a player is the strategy choices of the other players, the pr iors of other players on the choice of other players, the priors over priors and so on.We provide a complete characterization between the extent of knowledge about the rationality of players and their ability to successfulIy eliminate strategies which are not best responses. This paper therefore provides the informational foundations of iteratively unàominated strategies and rationalizable strategic behavior (Bernheim (1984) and Pearce (1984». Moreover, sufficient condi tions are also found for Nash equilibrium behavior. We also provide Aumann's (1985) results on correlated equilibria .

Social entrepreneurship practices and social change In Brazil: a qualitative study in three non-governmental organizations

Social Entrepreneurship (SE) has attracted growing interest from a wide variety of actors over the last 30 years, especially due to a general agreement that it could be an important tool for tackling many of the world’s social ills. In the academic sphere, this growing interest did not translate into a matured field of study. Quite the opposite, a quick look at this literature makes it evident that: SE has been consistently subjected to numerous theoretical discussions and disagreements, especially over the definition of the concept of SE which is often based on a taken-for-granted notion of social change; it has been more systematically investigated in restricted contexts, often leaving aside so called developing/emerging countries like Brazil and especially lacking in-depth qualitative studies; SE literature lags behind SE practices and few studies focus on how SE actually occurs in a daily and bottom-up manner. In order to address such gaps, this thesis examines how social entrepreneurship practices accomplish social change in the context of Brazil. In this investigation I conducted an inductive practice-based, qualitative/ethnographic study in three Non-Governmental Organizations (NGOs) located in different cities in the Brazilian state of São Paulo. Data collection lasted from February 2014 until March 2015 and was mainly done through participant observations and through in-depth unstructured conversations with research participants. Secondary data and documents were also collected whenever available. The participants of this study included a variety of the studied organizations’ stakeholders: two founders, volunteers, employees, donors and beneficiaries. Observation data was kept in fieldnotes, conversations were recorded whenever possible and were later transcribed. Data was analyzed through an iterative thematic analysis. Through this I identified eight recurrent themes in the data: (1) structure; (2) relationship with other organizational actors (sub-themes: relationship with state, relationship with businesses and relationship with other NGOs); (3) beliefs, spirituality and moral authority; (4) social position of participants, (5) stakeholders’ mobilization and participation; (6) feelings; (7) social purpose; and (8) social change. These findings were later discussed under the lens of practice theory, and in this discussion I argue and show that, in the context studied: (a) even though SE embraces a wide variety of different social purposes, they are intertwined with a common notion of social change based on a general understanding and aspiration for social equality; (b) this social change is accomplished in a processual and ongoing manner as stakeholders from antagonistic social groups felt compelled to and participated in SE practices. In answering the proposed research question the contributions of this thesis are: (i) the elaboration a working definition for SE based on its relationship with social change; (ii) providing in-depth empirical evidence which accounts for and explains this relationship; (iii) characterizing SE in the Brazilian context and reflecting upon its transferability to other contexts. This thesis also makes a methodological contribution, for it demonstrates how thematic analysis can be used in practice-based studies.

Jovens, políticas públicas e estratégias administrativas: o papel das ideias e dos discursos na constituição do campo e na trajetória das políticas de juventude no Brasil

O objetivo dessa dissertação é analisar como as ideias sobre a juventude, representadas pelos discursos oriundos de diferentes materiais empíricos – documentos governamentais e de organizações da sociedade civil e entrevistas não-estruturadas – e a forma pela qual os jovens são reconhecidos como sujeitos de direitos influenciaram o processo de formação das políticas de juventude no Brasil e institucionalização do tema em âmbito federal, assim como a escolha pelas estratégias administrativas que constituem as principais formas de ação e de gestão governamental no tema. Para isso, adotamos como ponto de partida a reflexão sobre o uso da retórica, por meio de metáforas e narrativas na formação e trajetória das políticas, a existência de coalizões discursivas em seu desenvolvimento e a utilização de frames (enquadramentos interpretativos) no exame dos pontos de inflexão das ações para a juventude no Brasil. Em seguida, identificamos as principais ideias sobre as juventudes presentes no campo e analisamos como elas alimentaram o reconhecimento dos jovens enquanto segmento social diferenciado dos demais em função da sua “condição juvenil” e enquanto sujeitos de direitos integrais. Com base nessas concepções, examinamos a criação e a definição as principais funções da Secretaria Nacional de Juventude, a partir de um debate sobre o conceito de transversalidade, e a formulação e trajetória do Programa Nacional de Inclusão de Jovens (PROJOVEM), adentrando o debate sobre a intersetorialidade nas políticas públicas. A principal contribuição dessa pesquisa foi relacionar como as ideias e discursos influem não apenas na formação de políticas, mas também como as construções sociais que emergem do campo, balizadas pelo reconhecimento dos sujeitos de direitos, também impactam nas estratégias de gestão. Conclui-se, ainda, que apesar da crescente importância atribuída à gestão transversal e à articulação intersetorial na gestão das políticas de juventude no Brasil, são as próprias concepções que orientam sua escolha como estratégias administrativas das quais decorrem os principais limites para a sua operacionalização cotidiana pela administração pública brasileira em nível federal.
