The negotiations of mega agreements between the US and the Pacific countries (TPP) and between the US and the EU (TTIP) are raising the attention of experts on international trade law and economics. TPP and TTIP are proclaimed to be the designers of the rules for the XXI Century. Old trade instruments such as tariffs are said to be no more important for TTIP because tariffs are negligible among those partners but significant to for TPP. Another relevant agreement in negotiation is between the EU and Mercosul, where tariffs are the most important issue in discussion. The main purpose of this paper is to shows that tariff are important for all these agreements, not because of its nominal value, but because the impacts of exchange rate misalignments on tariffs are so significant that all concessions can be distorted by overvalued and by devaluated currencies. The article is divided into several sections: the first gives an introduction to the issue; the second explains the methodologies used to determine exchange rate misalignments and also presents some results for Brazil, US and China; the third summarizes the methodology applied to calculate the impacts of exchange rate misalignments on the level of tariff protection through an exercise of “misalignment tariffication” and examines the effects of exchange rate variations on tariffs and their consequences for the multilateral trading system; the fourth creates a methodology to estimate exchange rates against a basket of currencies (a virtual currency of the World) and a proposal to deal with persistent and significant misalignments related to trade rules. The fifth presents some estimates for the main PTAs. The conclusions are present in the last section

This paper deals with the testing of autoregressive conditional duration (ACD) models by gauging the distance between the parametric density and hazard rate functions implied by the duration process and their non-parametric estimates. We derive the asymptotic justification using the functional delta method for fixed and gamma kernels, and then investigate the finite-sample properties through Monte Carlo simulations. Although our tests display some size distortion, bootstrapping suffices to correct the size without compromising their excellent power. We show the practical usefulness of such testing procedures for the estimation of intraday volatility patterns.

The impact of a mandatory tax on profits which is transferred to workers is analyzed in a general equilibrium entrepreneurial model. In the short run, this distortion reduces the number of firms and the aggregate output. In the long run, if capital and labor are bad substitutes, it fosters capital accumulation and increases the aggregate output. In a small open economy with free movement of capital, it improves the welfare of the economy's average individual. One concludes that the benefits of sharing schemes may go beyond the short run employment-stabilization goal focused by the profit sharing literature.

We identify trade in goods opportunities in a EU-Mercosul free trade area. Gains for Mercosul are rather concentrated, being mostly associated to a few agricultural commodities nowadays facing high protection barriers. EU gains are evenly spread, comprising a variety of market penetration possibilities. Trade deviation by the EU products is never higher than trade creation, confirming their international competitiveness and signalling that a great distortion of Mercosul’s imports won’t take place. Balanced gains exist for both sides; for Mercosul, the agreement can act as a first serious trial for future liberalisations with other developed partners, and as a warning on needed competitiveness improvements.

O Estado e o mercado são instituições complementares. O Estado é a instituição principal que coordena as sociedades modernas; é o sistema constitucional e a organização que o garante; é o principal instrumento através do qual as sociedades democráticas estão moldando o capitalismo de modo a alcançar seus próprios objetivos políticos. Os mercados são instituições baseadas na competição, regulada pelo Estado para que contribuam com a coordenação da economia. Enquanto o liberalismo emergiu no século 18 para combater o estado autocrático, desde os anos 1980 o neoliberalismo (uma distorção maior do liberalismo econômico) tornou-se dominante e montou um assalto ao estado em nome do mercado, mas eventualmente também atacou o mercado. A macroeconomia neoclássica e a teoria da escolha pública foram as meta-ideologias que deram a esse assalto um apelo ‘científico’ e matemático.

Os Juizados Especiais foram criados para proporcionar acesso à justiça, de forma simples e rápida, sem custos, objetivando resolver conflitos de menor complexidade, de modo informal e preferencialmente através da conciliação. Decorridas mais de duas décadas desde a sua implantação, no Rio Grande do Sul, o sistema não vêm tendo a devida atenção, quer de parte dos operadores, quer de parte do próprio Judiciário. O risco de contaminação das práticas do sistema tradicional de justiça, burocrático e formalista e, por isso mesmo, moroso, exige medidas de administração judiciária que evitem o desvirtuamento dos princípios com base nos quais os Juizados Especiais foram concebidos. A correta atuação dos Juízes Presidentes dos Juizados Especiais, a orientação aos servidores que nele atuam, a prévia preparação dos juízes leigos e conciliadores para o exercício das relevantes funções que lhes são atribuídas, o comprometimento dos integrantes das Turmas Recursais com a unidade do sistema e, fundamentalmente, gestão deste pelo órgão estadual responsável pela coordenação e supervisão dos Juizados Especiais, são medidas que, juntamente com os necessários investimentos em informatização, incentivo à inovação e ao uso das novas tecnologias, padronização de procedimentos, aperfeiçoamento dos bancos de dados e sistema estatístico, podem promover melhorias significativas no seu desempenho.

Over the last years we have seen a significant increase in scholarly production within the organization studies field in Brazil. However it is still not representative. The tendency to consume foreign and fashionable ideas unrestrainedly, to make use of imported, universal and non-contextualized explanations to inquiry phenomenon which are essentially local and particular, make it difficult to develop a true Brazilian tradition. This work is a result of an ambitious ethnographic adventure" of an acknowledged apprentice of sociologist Pierre Bourdieu's large body of knowledge. It is about taking reflexivity to the limit. It is about learning "through the body" in an effort - both theoretical and empirical - to investigate a Brazilian organizational phenomenon which reproduces the hierarchical side of our society and, under the disguise of the legitimacy offered by organizational discourse, help keeping the very structure of our society in a silent but powerful way. I also want this work to be an alert for the importance of contextualization as a means to avoid a recurring distortion of the scholarly production in administrative science: the mobilization of theoretical references in such a safe way that make explicitness totally unnecessary, the appropriation of concepts whose essence is strange to the nature of the very phenomenon which they aim to explain, and the insistence in the impersonal style, in third-voice narratives, as if it were possible to produce knowledge in social sciences with absolute impartiality.

Atualmente a gestão de contas a receber passou a ter uma maior importância para a alta administração das empresas. A estabilidade monetária dos últimos anos apresenta com maior clareza os resultados desta gestão. Não existe mais espaço para a ineficiência nesta área, pois ela é refletida automaticamente através do aumento da inadimplência ou aumento dos prazos de recebimento, diferentemente do passado, quando a inflação escondia as suas falhas através das distorções de valores e também de uma preocupação quase que exclusiva, por parte desta alta administração, na correção dos seus ativos financeiros. o presente trabalho tem como objetivo analisar a atual e novas propostas de gestão de contas a receber para identificar a mais adequada para a Indústria de Confecção Triumph. A análise partirá da identificação do atual estágio de gestão desta área nas empresas brasileiras, fazendo a sua descrição detalhada e mostrando os seus pontos fortes e fracos. Em seguida serão realizadas pesquisas identificadoras de diferentes instrumentos, políticas e procedimentos utilizados, mostrando também os seus pontos fortes e fracos, finalmente o trabalho apresentará um modelo-proposta de gestão eficaz para a Triumph. Como referencial teórico serão analisados os conceitos e as ferramentas da gestão estratégica, reengenharia, marketing, recursos humanos, tecnologia de informação, estatística aplicada à área, análise dos demonstrativos financeiros e administração do capital de giro, buscando interligar nestes instrumentos e teorias o que existe de mais adequado para uma gestão eficaz do tema em estudo.

This paper demonstrates that the applied monetary models - the Sidrauski-type models and the cash-in-advance models, augmented with a banking sector that supplies money substitutes services - imply trajectories which are Pareto-Optimum restricted to a given path of the real quantity of money. As a consequence, three results follow: First, Bailey’s formula to evaluate the welfare cost of inflation is indeed accurate, if the longrun capital stock does not depend on the inflation rate and if the compensate demand is considered. Second, the relevant money demand concept for this issue - the impact of inflation on welfare - is the monetary base. Third, if the long-run capital stock depends on the inflation rate, this dependence has a second-order impact on welfare, and, conceptually, it is not a distortion from the social point of view. These three implications moderate some evaluations of the welfare cost of the perfect predicted inflation.

The purpose of this work is to provide a brief overview of the literature on the optimal design of unemployment insurance systems by analyzing some of the most influential articles published over the last three decades on the subject and extend the main results to a multiple aggregate shocks environment. The properties of optimal contracts are discussed in light of the key assumptions commonly made in theoretical publications on the area. Moreover, the implications of relaxing each of these hypothesis is reckoned as well. The analysis of models of only one unemployment spell starts from the seminal work of Shavell and Weiss (1979). In a simple and common setting, unemployment benefits policies, wage taxes and search effort assignments are covered. Further, the idea that the UI distortion of the relative price of leisure and consumption is the only explanation for the marginal incentives to search for a job is discussed, putting into question the reduction in labor supply caused by social insurance, usually interpreted as solely an evidence of a dynamic moral hazard caused by a substitution effect. In addition, the paper presents one characterization of optimal unemployment insurance contracts in environments in which workers experience multiple unemployment spells. Finally, an extension to multiple aggregate shocks environment is considered. The paper ends with a numerical analysis of the implications of i.i.d. shocks to the optimal unemployment insurance mechanism.

Este trabalho objetivou investigar através de um estudo exploratório o atual estágio que se encontra o arrendamento mercantil ( Leasing Financeiro) no Brasil, identificando as disposições legais que orientam o tratamento procedendo a uma análise crítica comparativa das formas de, contabilizar o "leasing". Nesse sentido, procedeu-se a uma revisão bibliográfica das principais abordagens existentes no exterior e no Brasil e a partir das quais se criou o Plano de Referência que fundamentou a pesquisa. Em razão do propósito descritivo e comparativo do trabalho, optou-se pelo estudo de caso, tendo em vista as vantagens que o método oferece. Com base nos dados colhidos da pesquisa, fez-se um reordenamento nas demonstrações contábeis publicadas, de modo a permitir estudo comparativo, quando se utilizar como alternativa a contabilização do "leasing" (arrendamento mercantil) na forma de financiamento. Os resultados obtidos permitiram identificar as principais distorces nas demonstrações contábeis e fazer uma análise econômico-financeira e, ainda, possibilitaram que se chegasse a importantes conclusões, além de ensejarem algumas recomendações e sugestões para futuras pesquisas.

We report the results of an exploratory data analysis of the Brazilian securities lending market. The analysis is performed over the full historical data set of each individual loan offer and loan contract negotiated between January 2007 and August 2013. We give a quantitative description of volume and loan fee trends and fee dependence on asset characteristics. We also unveil new stylized facts specific to the Brazilian market on market access asymmetries between different types of investors. The emerging picture is that the Brazilian securities lending market is a complex environment with specific frictions and strong asymmetries among players. In particular, we describe a tax arbitrage operation performed by domestic mutual funds which generates a significant distortion in the data. In one such event, we estimate additional aggregate profits of 24.25 million Reais (around 10 million Dollars).

This paper uses a multivariate response surface methodology to analyze the size distortion of the BDS test when applied to standardized residuals of rst-order GARCH processes. The results show that the asymptotic standard normal distribution is an unreliable approximation, even in large samples. On the other hand, a simple log-transformation of the squared standardized residuals seems to correct most of the size problems. Nonethe-less, the estimated response surfaces can provide not only a measure of the size distortion, but also more adequate critical values for the BDS test in small samples.
