Da irrelevância do mercado relevante: economistas, teoria econômica e política antitruste no Brasil

O objetivo desta dissertação é analisar a construção social da política antitruste no Brasil, focando no papel dos economistas e de suas teorias na prática organizacional do Conselho Administrativo de Defesa Econômica (CADE). Com base na sociologia econômica contemporânea, a pesquisa traça um histórico institucional da política e do órgão antitruste argumentando que o conhecimento econômico, ao ser utilizado e institucionalizado na prática organizacional da agência, tornou as decisões jurídicas uma questão econômica e acabou construindo uma poderosa ferramenta de performatividade da teoria econômica. A dissertação busca realçar o processo político performativo de economicização implícito na construção isomórfica de políticas econômicas.

Além das versões: possibilidades da narrativa em entrevistas de história oral

The work with oral history consists of recording interviews which have historical and documental proprieties, with actors/actresses or witnesses of events, conjunctures, movements, institutions and ways of living along the contemporary history. One of its basic foundations is the narrative. An event or a situation lived by the interviewee can not be transmitted to any other person without being narrated. That means that it frames itself (meaning that it does become something) at the very moment of the interview. By telling his/her life experiences, the interviewee transforms what has been lived into language, selecting and organizing facts according to some determined meanings. This work of language in crystallising images (images which refer to, and mean again, life experience) is common in all narratives - and we do know that sometimes it is much more successful than others (just the way some oral history interviews are certainly more successful than others). However, perhaps we have not given yet all the attention needed to this work of language in the oral sources.

Board of directors and top management team: a study on CEO relative power and financial return

Best corporate governance practices published in the primers of Brazilian Securities and Exchange Commission and the Brazilian Corporate Governance Institute promote board independence as much as possible, as a way to increase the effectiveness of governance mechanism (Sanzovo, 2010). Therefore, this paper aims at understanding if what the managerial literature portraits as being self-evident - stricter governance, better performance - can be observed in actual evidence. The question answered is: do companies with a stricter control and monitoring system perform better than others? The method applied in this paper consists on comparing 116 companies in respect to the their independence level between top management team and board directors– being that measured by four parameters, namely, the percentage of independent outsiders in the board, the separation of CEO and chairman, the adoption of contingent compensation and the percentage of institutional investors in the ownership structure – and their financial return measured in terms return on assets (ROA) from the latest Quarterly Earnings release of 2012. From the 534 companies listed in the Stock Exchange of Sao Paulo – Bovespa – 116 were selected due to their level of corporate governance. The title “Novo Mercado” refers to the superior level of governance level within companies listed in Bovespa, as they have to follow specific criteria to assure shareholders ´protection (BM&F, 2011). Regression analyses were conducted in order to reveal the correlation level between two selected variables. The results from the regression analysis were the following: the correlation between each parameter and ROA was 10.26%; the second regression analysis conducted measured the correlation between the independence level of top management team vis-à-vis board directors – namely, CEO relative power - and ROA, leading to a multiple R of 5.45%. Understanding that the scale is a simplification of the reality, the second part of the analysis transforms all the four parameters into dummy variables, excluding what could be called as an arbitrary scale. The ultimate result from this paper led to a multiple R of 28.44%, which implies that the combination of the variables are still not enough to translate the complex reality of organizations. Nonetheless, an important finding can be taken from this paper: two variables (percentage of outside directors and percentage of institutional investor ownership) are significant in the regression, with p-value lower than 10% and with negative coefficients. In other words, counter affirming what the literature very often portraits as being self-evident – stricter governance leads to higher performance – this paper has provided evidences to believe that the increase in the formal governance structure trough outside directors in the board and ownership by institutional investor might actually lead to worse performance. The section limitations and suggestions for future researches presents some reasons explaining why, although supported by strong theoretical background, this paper faced some challenging methodological assumptions, precluding categorical statements about the level of governance – measured by four selected parameters – and the financial return in terms of financial on assets.

Planejamento agregado de estoques

Estuda o problema do dimensionamento de estoques agregado, em função dos custos envolvidos e de objetivos estabelecidos. Apresenta os sistemas básicos de gestão de estoques: lote fixo, revisão periódica, máximo e mínimo e reposição opcional. São discutidos diversos tipos de modelos de mínimo custo para o dimensionamento dos estoques operacionais: modelos de estágio único; lotes econômicos com permissão de faltas; modelos que admitem variação no valor dos custos envolvidos. São também analisados diversos modelos probabilísticos para o dimensionamento dos estoques de segurança, tanto para itens de alta demanda (modelos de distribuição normal, gama, etc.) como de baixa demanda (modelos de Poisson, Laplace, etc.). Para os estoques agregados, e proposto o modelo GEA - GESTÃO DE ESTOQUES AGREGADOS, que dimensiona os parâmetros de controle dos itens individuais em função de objetivos agregados. São ainda apresentados modelos de previsão de demanda a curto prazo e de classificação dos itens de estoque em função do seu Valor de Demanda.

O impacto da burocracia nas pequenas e microempresas: uma análise do arcabouço legal

Esse trabalho se debruça sobre os problemas enfrentados pelas pequenas e microempresas no Estado do Rio de Janeiro, dadas as circunstâncias de uma estrutura arcaica e burocratizada do Estado brasileiro, que transforma o ato de empreender em uma verdadeira aventura, pois além dos desafios e riscos inerentes ao próprio negócio, a burocracia elimina a maioria das empresas ainda nos primeiros anos de vida. O segmento focado nesse trabalho sofre, ainda mais, pela baixa capacidade de mobilização e representatividade, não tendo, assim, como se defender de um estado sócio apenas do sucesso e jamais do fracasso. A própria legislação funciona como um entrave, com regras de todo dissociadas da realidade econômica, estabelecendo procedimentos que ao invés de serem estímulos se transformam em obstáculos muitas vezes intransponíveis para as pequenas e microempresas. O emaranhado de leis cria um cenário propício à corrupção, consequência direta da falta de objetividade e critério daqueles com a função de legislarem. Os exemplos de leis mostrados ao longo do texto retratam a verdadeira sangria na saúde dessas empresas, assim como a quantidade de novos Projetos de Lei apresentados a cada ano, demonstra que, infelizmente, ainda estamos longe de uma mudança de rumos. O trabalho procura apontar através de alguns dados o prejuízo para a economia do Estado, pois são elas, pequenas e microempresas, ao contrário do que muitos pensam, as maiores empregadoras, sendo, portanto, de vital importância que as suas dificuldades sejam tratadas como prioridade. Embora, como dito, o Estado do Rio de Janeiro tenha servido como exemplo do modelo vigente, essa realidade é praticamente a mesma em todas as demais Unidades da Federação, deixando clara a importância de uma mobilização geral capaz de mudar o rumo dessa história. Porém, fica claro também que essa transformação passa por uma mudança de mentalidade, pois sem isso, todas as vitórias serão pontuais, sem forças para a construção de um novo cenário de negócios.

Global law in pieces fragmentation, regimes and pluralism

The idea that life undergoes a process of functional differentiation, and that, as a consequence, law becomes increasingly specialized – and maybe even transforms in its very nature – is now widespread. The specialized clusters of law or regulation are very often called regimes, in the international arena, international or transnational regimes. This paper deals, first, with three strong representations of international regimes and discusses some of their problems. It argues that, in order to make a good use of the category, it is necessary to keep in mind the differentiation between law and non-law in the wider context of governance. It then turns, firstly, to the notion of regimes as fragments of a unified and coherent public international law order and, secondly, as meeting points of regulations emerging from different legal orders as well as from other non-legal sources. Within public international law, regimes are seen as related to what is called the double fragmentation of that legal order. As clusters of regulation within a wider global regulatory order, regimes are put in relation to two types of legal or regulatory pluralism.

Inflation persistence and flexible prices

The inability of rational expectation models with money supply rules to deliver inflation persistence following a transitory deviation of money growth from trend is due to the rapid adjustment of the price level to expected events. The observation of persistent inflation in macroeconomic data leads many economists to believe that prices adjust sluggishly and/or expectations must not be rational. Inflation persistence in U.S. data can be characterized by a vector autocorrelation function relating inflation and deviations of output from trend. In the vector autocorrelation function both inflation and output are highly persistent and there are significant positive dynamic cross-correlations relating inflation and output. This paper shows that a flexible-price general equilibrium business cycle model with money and a central bank using a Taylor rule can account for these patterns. There are no sticky prices and no liquidity effects. Agents decisions in a period are taken only after all shocks are observed. The monetary policy rule transforms output persistence into inflation persistence and creates positive cross-correlations between inflation and output.

Exploring different social media users from the millennials’ generation: a cross-cultural behavioral analysis of brazilian users of Facebook and chinese users of RenRen

With the increasing importance of digital communication and its distinct characteristics, marketing tools and strategies adopted by companies have changed dramatically. Among the many digital marketing tools and new media channels available for marketers, the phenomenon known as social media is one of the most complex and enigmatic. It has a range that still is quite unexplored and deeply transforms the present view on the promotion mix (Mangold & Faulds, 2009). Conversations among users on social media directly affect their perceptions on products, services and brands. But more than that, a wide range of other subjects can also become topics of conversations on social media. Hit songs, sporting events, celebrity news and even natural disasters and politics are topics that often become viral on the web. Thus, companies must grasp that, and in order to become more interesting and relevant, they must take part in these conversations inserting their brands in these online dynamic dialogues. This paper focuses on how these social interactions are manifested in the web in to two distinct cultures, Brazil and China. By understanding the similarities and differences of these cultures, this study helps firms to better adjust its marketing efforts across regions, targeting and positioning themselves, not only geographically and culturally, but also across different web platforms (Facebook and RenRen). By examining how companies should focus their efforts according to each segment in social media, firms can also maximize its results in communication and mitigate risks. The findings suggest that differences in cultural dimensions in these two countries directly affect their virtual social networking behavior in many dimensions (Identity, Presence, Relationships, Reputation, Groups, Conversations and Sharing). Accordingly, marketing efforts must be tailored to each comportment and expectations.

Um modelo de leilões com conteúdo local: análise e modelagem dos leilões de concessão de blocos exploratórios de petróleo e gás promovidos pela ANP no Brasil

Os leilões para concessão de blocos de petróleo no Brasil utilizam uma equação para formar a pontuação que define o vencedor. Cada participante deve submeter ao leiloeiro um lance composto por três atributos: Bônus de Assinatura (BA), Programa Exploratório Mínimo (PEM) e Conteúdo Local (CL). Cada atributo possui um peso na equação e a nota final de cada participante também depende dos lances ofertados pelos outros participantes. Apesar de leilões de petróleo serem muito estudados na economia, o leilão multi-atributos, do tipo máxima pontuação, ainda é pouco analisado, principalmente como mecanismo de alocação de direitos minerários. Este trabalho destaca a inserção do CL como atributo que transforma a estrutura, do que poderia ser um leilão simples de primeiro preço, em um leilão multi-atributos de máxima pontuação. Demonstra-se como o CL, através da curva de custos do projeto, está relacionado também ao Bônus de Assinatura, outro importante atributo da equação. Para compreender o impacto do fenômeno da inserção do CL, foram criados três casos de leilões hipotéticos, onde, dentre outras simplificações, o programa exploratório mínimo foi fixado para todas as empresas envolvidas. No caso base (Sem CL), simula-se a estrutura de um leilão de primeiro preço, onde apenas o BA define o vencedor do leilão. Já no caso forçado (CLO=CLR), há inserção do atributo CL, sendo o participante obrigado a cumprir o CL ofertado. Por fim, o caso completo (Com Multa) permite que o participante preveja a aplicação de multa por descumprimento do CL ofertado e, caso haja benefício econômico, descumpra efetivamente o CL ofertado. Considerando estes casos, argumenta-se que, apesar do o lucro das empresas e a eficiência do leilão não serem alterados, a inclusão do conteúdo local na estrutura do leilão pode ter reflexos consideráveis na receita do governo.
