Important, unimportant a critical anticipation of the assumptions of legal positivism in Alice in Wonderland

Almost a full century separates Lewis’ Alice in Wonderland (1865) and the second, lengthier and more elaborate edition of Hans Kelsen’s Pure Theory of Law (1960; first edition published in 1934). And yet, it is possible to argue that the former anticipates and critically addresses many of the philosophical assumptions that underlie and are elemental to the argument of the latter. Both texts, with the illuminating differences that arise from their disparate genre, have as one of their key themes norms and their functioning. Wonderland, as Alice soon finds out, is a world beset by rules of all kinds: from the etiquette rituals of the mad tea-party to the changing setting for the cricket game to the procedural insanity of the trial with which the novel ends. Pure Theory of Law, as Kelsen emphatically stresses, has the grundnorm as the cornerstone upon which the whole theoretical edifice rests2. This paper discusses some of the assumptions underlying Kelsen’s argument as an instance of the modern worldview which Lewis satirically scrutinizes. The first section (Sleepy and stupid) discusses Lewis critique of the idea that, to correctly apprehend an object (in the case of Kelsen’s study, law), one has to free it from its alien elements. The second section (Do bats eat cats?) discusses the notion of systemic coherence and its impact on modern ways of thinking about truth, law and society. The third section (Off with their heads!) explores the connections between readings of systems as neutral entities and the perpetuation of political power. The fourth and final section (Important, Unimportant) explains the sense in which a “critical anticipation” is both possible and useful to discuss the philosophical assumptions structuring some positivist arguments. It also discusses the reasons for choosing to focus on Kelsen’s work, rather than on that of Lewis’ contemporary, John Austin, whose The Province of Jurisprudence Determined (published in 1832) remains influential in legal debates today.

A economia política da corrupção

The aim of this paper is to show that corruption shoud be an important subject for economic analysis and modern positive political economy. I sustain that one could construct general models of corrupt behavior with the notion of definition of corruption linked with the notion of institutions and incentives. Socondly, I discuss critically the weberian notions of public action to purpose finally, a political economy approach to the problem. The main conclusion of this essay is that economics and modern political economy could be extremely useful tools in the study of this social and economic fact.

Imperfectly credible disinflation under endogenous time-ependent pricing

The real effects of an imperfectly credible disinflation depend critically on the extent of price rigidity. Therefore, the study of how policymakers’ credibility affects the outcome of an announced disinflation should not be dissociated from the analysis of the determinants of the frequency of price adjustments. In this paper we examine how credibility affects the outcome of a disinflation in a model with endogenous timedependent pricing rules. Both the initial degree of price ridigity, calculated optimally, and, more notably, the changes in contract length during disinflation play an important role in the explanation of the effects of imperfect credibility. We initially evaluate the costs of disinflation in a setup where credibility is exogenous, and then allow agents to use Bayes rule to update beliefs about the “type” of monetary authority that they face. In both cases, the interaction between the endogeneity of time-dependent rules and imperfect credibility increases the output costs of disinflation, but the pattern of the output path is more realistic in the case with learning.

Desempenho profissional do psicólogo escolar: relação entre conhecimento da amplitude de suas funções e limites institucionais

Este estudo foi elaborado em função da necessidade de sistematização das múltiplas questões levantadas em torno da eficácia da Psicologia Escolar que, de certa forma, esvaziam e comprometem sua vital importância no contexto Educacional brasileiro. Para um maior aprofundamento na análise das questões referentes à atuação do Psicólogo Escolar, utilizou-se enfoque epistemológico referente à construção do "real", através dos "possíveis" e dos "necessários" em Educação. Foi realizada uma investigação de campo com trinta e três Psicólogos Escolares de escolas particulares com o objetivo de analisar suas funções, a fim de diagnosticar as limitações das mesmas e suas possíveis causas, bem como a amplitude de suas propostas de atuação. Foram levantadas hipóteses para uma melhor compreensão dos motivos que levariam o Psicólogo Escolar a desempenhar suas funções numa tendência mais institucional dentro do contexto educativo ou mais clínica. Os resultados revelam que 67% dos Psicólogos Escolares conhecem a amplitude de suas funções e procuram assumí-las plenamente apesar dos limites que a Instituição oferece, estando sua atuação, mais ligada aos aspectos institucionais. Foi, igualmente, feita uma análise dos motivos que levam os Diretores de escolas a contratar um Psicólogo Escolar, sendo utilizada uma amostra de trinta e quatro escolas, que possuem ou não Psicólogos Escolares. A partir desses resultados pode-se afirmar que quanto mais o Psicólogo Escolar conhecer e assumir a amplitude de suas funções, mais facilmente poderá romper com os limites e dificuldades da própria Instituição, uma vez que, através da análise das possibilidades e necessidades do contexto institucional, terá condições para viabilizar a construção de um "real" educativo. Na medida em que o Psicólogo Escolar assumir sua identidade profissional, abrirá novas perspectivas de trabalho e espaços dentro da própria instituição escolar.

Currículo por tema como alternativa ao curriculo dos cursos de graduação em administração

o presente texto trata de um estudo de campo sobre Currículo de Graduação em Administração, realizado em três etapas. A primeira delas foi direcionada para saber como estava o exercício da profissão de administrador, como se constituíam os elementos integrantes da formação acadêmica do público-alvo, qual a avaliação que os entrevistados faziam dos cursos e que propostas apresentavam para o currículo. A segunda fase respondeu questões sobre a interdisciplinaridadade das ciências sociais, as qualidades imprescindíveis ao administrador e as informações importantes para a formação de idéias visando a propor um formato curricular alternativo ao Currículo Tradicional. A última fase destinou-se, exclusivamente, a pesquisar a possibilidade de introdução efetiva de opções curriculares, destacando-se a proposta do Currículo por Tema, onde apareceram as interseções interdisciplinares feitas, em sentido vertical, pelos módulos, e as interseções intermodulares realizadas, em sentido horizontal, pelas disciplinas. Acredita-se que tais interseções ajudariam os estudantes na construção do seu propno conhecimento, habituando-os a tirar ilações, a fazer comparações, a chegar a conclusões, a analisar os fatos criticamente e a ter visão de conjunto dos fenômenos. Elas poderiam, ainda, auxiliá-los na compreensão global dos problemas ligados ao ambiente em que vivem.

Imperfectly credible disinflation under endogenous time-dependent pricing

The real effects of an imperfectly credible disinflation depend critically on the extent of price rigidity. Therefore, the study of how policymakers’ credibility affects the outcome of an announced disinflation should not be dissociated from the analysis of the determinants of the frequency of price adjustments. In this paper we examine how the policymaker’s credibility affects the outcome of an announced disinflation in a model with endogenous time-dependent pricing rules. Both the initial degree of price ridigity, calculated optimally, and, more notably, the changes in contract length during disinflation play an important role in the explanation of the effects of imperfect credibility. We initially evalute the costs of disinflation in a setup where credibility is exogenous, and then allow agents to update beliefs about the “type” of monetary authority that they face. We show that, in both cases, the interaction between the endogeneity of time-dependent rules and imperfect credibility increases the output costs of disinflation.

Addressing important econometric issues on how to construct theoretical based exchange rate misalignment estimates

Exchange rate misalignment assessment is becoming more relevant in recent period particularly after the nancial crisis of 2008. There are di erent methodologies to address real exchange rate misalignment. The real exchange misalignment is de ned as the di erence between actual real e ective exchange rate and some equilibrium norm. Di erent norms are available in the literature. Our paper aims to contribute to the literature by showing that Behavioral Equilibrium Exchange Rate approach (BEER) adopted by Clark & MacDonald (1999), Ubide et al. (1999), Faruqee (1994), Aguirre & Calderón (2005) and Kubota (2009) among others can be improved in two following manners. The rst one consists of jointly modeling real e ective exchange rate, trade balance and net foreign asset position. The second one has to do with the possibility of explicitly testing over identifying restrictions implied by economic theory and allowing the analyst to show that these restrictions are not falsi ed by the empirical evidence. If the economic based identifying restrictions are not rejected it is also possible to decompose exchange rate misalignment in two pieces, one related to long run fundamentals of exchange rate and the other related to external account imbalances. We also discuss some necessary conditions that should be satis ed for disrcarding trade balance information without compromising exchange rate misalignment assessment. A statistical (but not a theoretical) identifying strategy for calculating exchange rate misalignment is also discussed. We illustrate the advantages of our approach by analyzing the Brazilian case. We show that the traditional approach disregard important information of external accounts equilibrium for this economy.
