Crise financeira: o caso japonês

This paper aims to analyze the experience of Japan after the collapse of speculative bubbles in assets and the banking crisis in the 1990s. An analysis about the effectiveness of fiscal and monetary policy is conducted and the measures taken with respect to the banking sector are also discussed in this paper. The Japanese financial crisis experience suggests that the nature, speed and order in which the government implements measures determine, in large part, the magnitude and cost of the crisis. Therefore, in hindsight, it can be said that the following tasks were necessary: 1) recapitalize the banking sector; 2) restore credit; and 3) reinvigorate the economic activity through appropriate fiscal measures.

Avaliação econômica de diferentes composições veiculares empregadas no transporte rodoviário de madeira: estudo de caso

Transport is one the essential services for the development of most economic activities. In the forestry sector, the main transport used to carry wood from the forest to local consumption is road. The transport increases the producing costs of wood and may be responsible of a high percentage in the final price of the wood sold in the industry. To reduce the company’s costs and increase the efficiency of forest production those transport activities must be analyzed and improved. In that context, an economic analysis is the main objective of this work, evaluating three different types of log transport from a sawmill in São Paulo´s Southwest region. For this, a data collection was done to compound the costs and the incomes of timber transport, and that way, to do the economic analyses of each transport. The monitoring activities were done in the second 2013 half-year and the research achieved economic viability results utilizing tools and methods of Economic Engineering

Análise ambiental do comércio bilateral Brasil - China

A estrutura do comércio bilateral entre o Brasil e a República Popular da China - China alterou-se ao longo das décadas de 1990 e 2000 e dos anos 2010 e 2011, que correspondem ao período de análise. Os indicadores monetários e físicos aqui utilizados sugerem que essa relação bilateral de comércio apresenta impacto negativo sobre o meio ambiente e uma tendência exponencial deste impacto. Os indicadores físicos parecem permitir uma extrapolação maior do que os monetários: apesar da China estar contribuindo com uma parcela maior com as mudanças climáticas - maior valor absoluto de emissão de CO2 das exportações -, o Brasil está contribuindo proporcionalmente mais do que aquele país para a insustentabilidade global. Assim, a dinâmica dessa estrutura aponta para aumento da vulnerabilidade do setor exportador brasileiro, tanto no aspecto ambiental como no tecnológico, fator primordial para minimização do impacto sobre o ecossistema local e global

Análise sobre o comércio entre Brasil e União Européia e as barreiras não tarifárias que o afetam

Conduto, este comércio bilateral encontra entraves para seu desenvolvimento causados principalmente pela União Europeia, tais como barreiras não tarifárias (barreiras técnicas, sanitárias, fitossanitárias etc) além de exigências acerca de produtos exportados para o mercado europeu por países terceiros, como, por exemplo, medidas de rastreabilidade, certificação, rotulagem e conformidade com regras europeias. Este estudo visa analisar este comércio bilateral, os obstáculos existentes e como o Brasil lida com esta situação

Uma análise da economia subterrânea brasileira nos anos 2000

The presented text aims to evaluate the causes that leading to the development of the informal sector and primarily its consequences for the registered economy (formal). Therefore, defines the concept of the shadow economy, and sets out its varied activities. The objective is to analyze the growth of this phenomenon in Brazil, since its supposed rise in the early 70's until recent days. Finally, it will be introduced some measurement methods that allow estimating the size of the shadow economy. Among these methods, in order to evaluate the behavior of the informal sector in Brazil, it was used the MIMIC model (Multiple Indicators and Multiple Causes) that consists of a statistical theory of unobserved variables, or also called latent, which considers multiple causes and multiple effects or indicators. Thus, it will be developed the analysis of results obtained

How companies can sell their surplus production capacity of electric power in Brazil? This work was developed from the question presented and focusing on clarification of procedures to enter the Brazilian electricity market by providing basic guidelines based on resolutions by National Agency of Electric Energy, National System Operator procedures and rules of the Assembly of Electric Energy Commercialization. It features subsidy to companies that fit this profile to evaluate the possibility to sell their surplus electricity. The general aim was to analyze the procedures and the necessary steps to make this sale happen. Was developed through a literature review where an overview of the Brazilian electric sector and a case study of a company that has excess capacity of electricity, but doesn’t make its marketing. Resulted in the expected clarification as well as the incentive for companies through the information presented, the entry in this trade since power is still crucial to the country's economic growth and ensure its availability in quantity demanded is a challenge of the utmost importance for satisfactory results are achieved economic development contributing to the progress of our society

Análise dos royalties do petróleo sob a perspectiva jurídica

This research aims to discuss the division of royalties from a legal perspective and its substitute role towards the non-taxation at source, in other words the taxation of destiny at the Brazilian petroleum industry. The analysis aims to deal with the historical evolution in relation to the aspect of royalties’ payment and its deviation of compensatory character in order to supply the ICMS function. There are some specific study objects in this research: 1. how the transformation of royalties’ payment led to financial compensation; 2. to whom the transference of mineral rent belongs – to the UNIÃO or to the fortunate regions which the oil is extracted; 3. would a tax reform be enough to minimize the competition of States and Cities towards the royalties? The research aims to clarify the real expectation that States have on the royalties’ payment. There is no compensation for damage to the environment as it is stated by the initial characteristic of the Constitution, and, by the contrast, from a compensatory character, there is a lacking of taxation from the sector mentioned before, this fact damages the producing states checked out by this research

Utilização do cavaco de madeira como combustível alternativo para a produção de vapor de água em uma caldeira aquatubular com grelha fixa do tipo PIN HOLE

The steady increase in the price of oil and its derivatives, carbon credits, the concern with the environment combined with the precipitation of rain water and lack of water resources that Brazil has suffered in 2014 caused a migration of participation sources of energy in the Brazilian energy matrix. The hydropower sector suffered big drop at 2013 and is suffering so far, contributing thus to the generation and cogeneration of thermal energy using renewable energy sources such as: sugarcane bagasse, wood chips, rice husks, among others. The selling price of the electricity market reached the level of R$ 807, 00 MWh in January 2014 (Source: ANEEL), heating the Brazilian thermoelectric sector. Although thermoelectric use in bulk water as vaporizing fluid to produce electricity and use in various processes, water reuse plans have become an important factor in these industries. The increased use of biomass has been the bagasse which is allied to the sugarcane sector, strong market in Brazil, and consists basically use the rest of sugar cane, sugarcane industries that would play out. The sugar and ethanol industry is very unstable and only lasts for 6-8 months a year, and the remaining time in the period known as between crop that corresponds to the planting and harvesting of sugarcane and then enter the period of vintage which is the constant cane harvesting and crushing it. This instability of the market and the thermoelectric idle period leads the thermoelectric industries to seek other sources of renewable energy, such as wood chips (pine, Eucalyptus, Orange), rice husk, sorghum among others, to not be dependent on alcohol sector. The present work aims to study the use of wood chips as an alternative biomass for burning a fuel that essentially uses bagasse, the thermoelectric in question consists of two boilers that produce together 350 t / h ...

Uma análise das estratégias de manufatura adotadas por seis montadoras da indústria automobilística mundial

The Brazilian automotive industry has undergone profound changes during the 90’s decade, as a consequence of the market opening up through the liberation of automobile imports. The exposure of the Brazilian domestic market to competition with imported products of high quality and lower prices indicated the need for significant changes in those auto industries operating in this country, with the intention of making them competitive. To achieve these objectives management and production concepts were adopted, such as: the just-in-time philosophy; lean manufacturing; outsourcing; reengineering and increasing the rate of automation in both production and management systems. These changes helped to increase productivity and, in turn, reduced the level of employment in the sector, especially in activities where the required qualification levels were low. Despite this modernization, the Brazilian companies have committed themselves to meet the specific needs of the Brazilian market. The objective of this paper is to analyze and present manufacturing strategies from six manufacturers of automotive vehicles: Toyota in Japan, Fiat in Italy, Volkswagen in Brazil and Germany and General Motors in the U.S. and Brazil. The predominant method of research was from reviewing relevant literature, whereas the empirical data was analyzed qualitatively. The article seeks to identify the manufacturing strategies adopted by manufacturers located in the above countries, electing one automotive manufacturer to represent each country. The research demonstrated that the processes for production of automobiles in four plants located in, the U.S. (GM); Italy (Fiat); Japan (Toyota) and Germany (VW) are similar to those adopted in Brazilian industrial plants of the same companies (GM and VW), with differences of operations only in the business strategies adopted by each of them.
