Trade liberalization and the evolution of skill earnings differentials in Brazil

From 1988 to 1995, when trade liberalization was implemented in Brazil, relative earnings of skilled workers decreased. In this paper, we investigate the role of trade liberalization in explaining these relative earnings movements, by checking all the steps predicted by the HeckscherOhlin- style trade transmission mechanism. We find that: i) employment shifted from skilled to unskilled intensive sectors, and each Sector increased its relative share of skilled labor; ii) relative prices fell in skill intensive sectors; iii) tariff changes across sectors were not related to skill intensities, but the pass-through from tariffs to prices was stronger in skill intensive sectors; iv) the decline in skilled eamings differentials mandated by the price variation predicted by trade is very elose to the observed one. The results are compatible with trade liberalization, accounting for the observed rei ative eamings changes in Brazil.

The Brazilian 1994 stabilization plan: an analytical view

The Real Plan has succeeded in stabilizing the Brazilian inflation. The consumer price inflation has been reduced from 11260 percent per year, in June 1994, to an estimate of 8 percent in 1997. The lower inflation resulted in a remarkable income distribution, and in an increased private consumption. The plan managed to control the inflationary effects of the increased demand with some traditional measures: A more liberalized economy, a moving (and overvalued) exchange rate band, high interest rate differentials, and a tight domestic credit policy. The government has, so far failed to accomplish the fiscal adjustment. The price stabilization has largely depended on the current account deficit. However, macroeconomic indicators do not present reasons for concern about the current account sustainability, in the medium-run. The economy may be trapped in a low-growth vicious cycle, represented by a stop-and-go trend, due to the two-way endogencity between domestic saving and growth. Economic growth depends on policies in increase the public sector saving, to secure the privatization of the State enterprises, and to promote investments. The major problem for the government action is, as always, in the political sphere. Approximately 80 percent of the Central Government net revenue are allocated to the social sectors. Consequently, the fiscal reform will hue to deal with the problem of re-designing the public sector’s intervention in the social area. Most probably, it will be inevitable to cut the social area budget. This is politically unpleasant.

O papel de governança corporativa em companhias recentemente privatizadas: evidências brasileiras

Examinamos as diferenças de preço entre diferentes classes de ações em companhias abertas no Brasil com particular ênfase a empresas privatizadas, e discutimos o papel do controlador, liquidez, e problemas de governanças que influenciam esta diferença ao longo do tempo. Nos incluímos uma breve discussão sobre o sistema societário brasileiro, e seus efeitos sobre os acionistas, e as características do processo de privatização, antes de passar a análise econométrica. Encontramos evidência empírica que suporta a hipótese de que a razão ação sem direito a voto sobre a participação acionária total, liquidez, e tipo de controle majoritário, e mudanças na regulamentação são significativas na determinação das diferenças de preço entre ações.

O conhecimento científico do poder como pré-requisito para o exercício da função gerencial nas organizações privadas

Nowadays, management of Intellectual Capital seems to be one of the most efficacious alternatives so that companies may permanently develop competitive differentials to enable their survival in a market that confers paradigma status to globalization. Managers are searching for solutions aiming to attract and maintain in their boards professionals that might be able to develop these competitive differentials and assure to their companies the expected results and the business growth. In this environment, the manager¿s functions appears as a strategic function towards the organization¿s routine and yet suggests an evaluation about the professionals performance concerning challenges (efforts) that market requires. The amount of scientific knowledge which these professionals detain about power should be measured as well as the thought that this can improve their performance regarding their capacity to convince (induce) people. This research concerns those that look for empirical evidences and scientific arguments to confirm the supposition that power knowledge may in fact provide a superior performance of those professionals that are in charge of management functions. The reason and results here presented allow to: reevaluate managers duties in private organizations, improve executive training programs so as to be more productive and appropriated, change the selection methods used to recognize such executives and finally suggest a reevaluation about the real adequation of graduation and master degree courses in regards to professionals graduation which are capable to ingress in business market and take over leadership positions.

A utilização do valor econômico adicionado como ferramenta de gestão financeira

Lets imagine how should be fine to disclose a new measure form to investigate the businessman performance as if the job done is bringing back to the stockholder, the best results. Also, would be better to exists an executive compensation, by his add value created to the stockholder.The word ¿add value¿ is at the summit point on the financial world, all the companies are involved on creating add value" into the assets.So, the EVA (Economic Value Added) has come, a patented trade mark by a consulting corporation company, the Stern & Stewart Co. as a new indicator of companies performances.This assignment has motivated to running out na empirical research in order to find out the right methodology its qualitys and its differentials."

Uma análise do diferencial competitivo de hotéis associados a cadeias hoteleiras internacionais

The main purpose of this dissertation was to analyse whether hotels managed by international hotel chains present competitive differential when compared to hotels independently operated. This dissertation was only concerned with analyzing the benefits brought to the hotel, according to the marketing point of view, taking into consideration the differentials related to the brands, the distribution channels, the marketing budget and the commercial structure offered by the hotel chains to their affiliated hotels.This dissertation was developed through reading, as well as interviewing professionals of the area, such as hotels managers, hotel chains' directors, and consultant of hotel area in order to get to know their perceptions about the subject. Executive hotels under the luxury category were analyzed in the city of São Paulo.The conclusion was that hotels managed by international chains do present competitive differential in relation to the independently operated hotels. This differential is due to the usage of a brand known worldwide, the marketing budget, the sales and commercial structure of the hotels chains. This benefit is even bigger when the hotel is inside the international market.

Sistemas de controle de vendas no setor têxtil: um estudo exploratório

Esta dissertação estuda os sistemas de controle de vendas praticados pela indústria têxtil brasileira diante das mudanças ambientais ocorridas nas últimas duas décadas. O pressuposto básico para a utilização de sistemas de controle para a equipe de vendas é que através deles é possível dirigir e influenciar as atitudes e os comportamentos dos empregados para conseguir atingir seus objetivos, havendo uma estreita relação entre a forma como a gerência comercial monitora, dirige, avalia e recompensa as atividades dos seus vendedores e a efetividade da área comercial, sendo diferenciais decisivos para atender a pressão por competitividade e as exigências do mercado quanto ao posicionamento da equipe comercial frente ao novo cenário de negócios. Da revisão teórica foram levantados os oito principais modelos de sistemas de controle e aspectos importantes que devem ser considerados para a composição do sistema de cada empresa. A pesquisa foi conduzida entre os responsáveis por equipes de vendas no segmento têxtil nos elos onde vendas industriais são realizadas. Empregaram-se técnicas empíricas para o levantamento das freqüências de incidência dos aspectos estudados e foi possível constatar que os elos de fibras e filamentos, fiação, tecelagem, malharia e beneficiamento do segmento têxtil possuem sistemas de controle pertinentes com as características de venda industrial. Os controles formais estão ligados a resultados e os controles informais estão relacionados com o acompanhamento das atividades e capacidades do vendedor. Adicionalmente buscou-se captar a percepção dos responsáveis por equipes comerciais sobre sua efetividade nos aspectos de volume de vendas, lucratividade, participação de mercado e também satisfação do cliente.

Desequilíbrio cambial e crescimento econômico: uma análise empírica baseada no modelo Balassa-Samuelson

A maioria dos trabalhos empíricos atuais utiliza somente os diferenciais de produtividade para estimar o efeito Balassa-Samuelson. Porém, o modelo em que se baseia esta abordagem assume algumas hipóteses importantes que podem ser relaxadas. A primeira parte deste trabalho busca estimar o efeito Balassa-Samuelson relaxando a hipótese de que o setor produtor de bens não-comercializáveis tem o mesmo tamanho em todos os países do mundo. Posteriormente, utilizando uma abordagem proposta por Rodrik (2007), os resultados obtidos na estimação do efeito Balassa-Samuelson são utilizados para calcular um índice de desequilíbrio do câmbio real. Por fim, o efeito de desequilíbrios cambiais sobre o crescimento econômico é estimado, verificando se os resultados encontrados por Rodrik (2007) se mantêm.

On the long run effects of barriers to trade

We study the macroeconomic effects of international trade policy by integrating a Hecksher-Ohlin trade model into an optimal-growth framework. The model predicts that a more open economy will have higher factor productivity. Furthermore, there is a "selective development trap," an additional steady state with low income, to which countries may or may not converge, depending on policy. Income at the development trap falls as trade barriers increase. Hence, cross-country differences in barriers to trade may help explain the dispersion of per-capita income observed across countries. The effects are quantified and we show that protectionism can explain a relevant fraction of TFP and long-run income differentials across countries.

Gestão de custos utilizando sistema de custeio por atividade-ABC: comparação entre laboratório público e privado de análises clínicas em São Luís-MA.

Neste trabalho, é abordada a importância de se utilizar novas formas (métodos) de rastreamento dos custos indiretos, em instituições pública e privada, demonstrando quanta informação uma administração responsável, na área de saúde, especificamente no setor de laboratórios de análises clínicas, pode visualizar com a utilização do Sistema de Custeio Baseado em Atividade - ABC, em substituição aos sistemas tradicionais de apuração dos custos, tipo o Absorção. Como efeito de trabalho de pesquisa buscou-se estabelecer o método de estudo de casos em duas instituições sendo uma da estrutura de saúde pública de São Luís, e outra da estrutura privada, que também presta os mesmos serviços, todos sob uma mesma remuneração – o SUS. Neste trabalho, permitem-se compará-los e verificar qual a melhor estrutura, seus problemas, limitações para a formação de seus custos. Permite também a análise comparativa entre formatos existentes, tipo o Sistema de Custeio Baseado em atividade – ABC e o sistema de custeio pro absorção. As análises obtidas permitem concluir nestes dois casos que os custos podem ser melhores determinados por uma sistemática de apuração que possibilite desenvolver diferenciais que poderão determinar a sua competitividade e a permanência dos seus serviços. Estas informações permitiriam um melhor desempenho tanto na área pública, quanto o da área privada.

Market coupling in the power markets

The thesis analyses the European Unions’ effort to create an integrated pan-European electricity market based on “market coupling” as the proposed allocation mechanism for interconnector transfer capacity. Thus, the thesis’ main focus is if market coupling leads to a price convergence in interlinked markets and how it affects the behavior of electricity price data. The applied research methods are a qualitative, structured literature review and a quantitative analysis of electricity price data. The quantitative analysis relies on descriptive statistics of absolute price differentials and on a Cointegration analysis according to Engle & Granger (1987)’s two step approach. Main findings are that implicit auction mechanisms such as market coupling are more efficient than explicit auctions. Especially the method of price coupling leads to a price convergence in involved markets, to social welfare gains and reduces market power of producers, as shown on the example of the TLC market coupling. The market coupling initiative between Germany and Denmark, on the other hand, is evaluated as less successful and illustrates the complexity and difficulties of implementing market coupling initiatives. The cointegration analysis shows that the time series were already before the coupling date cointegrated, but the statistical significance increased. The thesis suggests that market coupling leads to a price convergence of involved markets and thus functions as method to create a single, integrated European electricity market.

Rent-sharing in Brazil: using trade liberalization as a natural experiment

This paper examines the extent of rent-sharing in Brazil, between 1988 and 1995, combining two different data sets: annual industrial surveys (pIA) and annual household surveys (PNADs). The aim is to use the trade liberalization policies that took place in Brazil in the early 1990s as a "natural experiment" to examine the impact ofproduct market rents on wages. We first estimate inter-industry wage differentials in Brazil, using the household surveys, afier controlling for various observable workers' characteristics. In a reduced form fixed effects equation, these controlled inter-industry differentials are seen to depend on the industries' rate of effective tariff. We also find that LSDV estimates of the effect of value-added per worker (computed using the industrial surveys) on the wage differentials are positive, but somewhat small. However, we find that instrumenting the valued-added with the effective tariffs more than doubles the estimated rent-sharing coefficient. The paper concludes that rent-sharing is prevalent in the Brazilian manufacturing sector, and this mechanism transferred part of the productivity gains due to trade liberalization to manufacturing workers in the form ofhigher (controlled) wage premium.
