Os Contratos de Licenciamento e a Eficiência Técnica dos Setores Industriais Brasileiros: Uma Análise à Luz do Método de Fronteira Estocástica e da Análise Envoltória de Dados (DEA)

The paper addresses the relationship between licenses and technical efficiency in a set of Brazilian industrial sectors. The main hypothesis is that licenses are negatively related with technical efficiency. To test this hypothesis, a stochastic and a non-parametric frontier were estimated for ten industrial sectors in the period from 1992 to 2000. Three results were found out: First, licenses and efficiency are negatively related; Second, the law’s adjustment contributed to the efficiency to all sectors. Third, law’s adjustment also emphasized the negative effect of licenses on technical efficiency. The arguments are the following: The first result is associated with licenses acting as entries barriers to specific industries. In the second argument, the law could have provided incentives to other aspects of industrial property other than the licenses, such as innovations, for an example. The third result may be associated with the inclusion of the compulsory license mechanism in the law, which may result in an increase in the number of licenses and also reducing the competition inside each sector, due to its compulsory aspects evolving firm behavior.Fronteira Estocástica, DEA, Contratos de Licenciamento, Reforma da Lei de Propriedade Industrial, Eficiência Técnica

Análise da eficiência relativa de terminais de contêineres brasileiros e implicações para expansão da capacidade do setor

O setor portuário é de fundamental importância para a economia, sobretudo em períodos de crescimento de fluxos de comércio exterior. A expansão da capacidade o setor portuário é custosa, seja na seleção de áreas adequadas, seja na construção da infraestrutura e oferta de equipamentos. Este trabalho aborda a questão da capacidade à luz do uso eficiente dos recursos. Com efeito, a partir da identificação o nível e ineficiência dos terminais brasileiros de contêineres, o estudo quantifica o acréscimo de capacidade útil possível pela simples utilização eficiente da estrutura atual. Nesse contexto, emprega a análise envoltória de dados para calcular o nível de eficiência de terminais portuários brasileiros de contêineres. O estudo inova ao empregar variáveis contábil-financeiras para estimar a fronteira de custo eficiência do setor, evidenciando maior nível de produto possível para dado custo. Como resultado, identificou-se eficiência média de 56%, para terminais privativos, e 82%, para terminais públicos. Por fim, estimou-se que o setor portuário nacional pode aumentar sua capacidade em 2-4,5 milhões de TEUs/ano apenas com ganhos de eficiência operacional

FURNISH : new methodologies to intervene in public space

Descripció del recurs: 23 maig 2023FURNISH is the acronym of Fast Urban Responses for New Inclusive Spaces and Habitat, a project centred on transforming streets by repurposing them. The project was born during the COVID-19 pandemic, when the emergency triggered the need to creatively reframe the general understanding, not only of our behaviour, but also of our environment. Public spaces should evolve and become more inclusive places for everyone, especially for the most vulnerable. Under these challenging circumstances, FURNISH, a project led by CARNET, emerged to rethink the public space, while taking action in an inclusive and necessary manner. This book summarises the project since its inception in 2020, the new methodologies applied to intervene the public space, and the fantastic experimental results. Enjoy the book!

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI
