Um estudo sobre a produtividade total dos fatores em setores de diferentes intensidades tecnólogicas

Este trabalho investigou o problema da determinação da produtividade total dos fatores em diversos setores industriais. Tal determinação se dá por meio de estimação de funções de produção, obtendo-se a produtividade a partir do resíduo destas estimações. A questão que aflora deste procedimento é a existência de correlação entre os resíduos e as variáveis explicativas, implicando em diversos vieses, entre eles o de simultaneidade, de variáveis omitidas e de seleção. Neste trabalho foram abordados diversos métodos de estimação de funções de produção, entre eles os métodos de Olley e Pakes e Levinsohn e Petrin. Todos os métodos foram aplicados a diversos setores da economia. A escolha dos setores se deu com base na intensidade tecnológica de cada um, sendo então escolhidos quatro setores de alta intensidade tecnológica e quatro de baixa intensidade tecnológica. A hipótese básica, fio condutor deste trabalho, é que os diversos métodos de estimação de funções de produção apresentam diferentes resultados quando aplicados a setores de diferentes intensidades tecnológicas. Um dos objetivos deste estudo foi identificar se determinado método seria mais adequado a setores de baixa intensidade tecnológica, enquanto outro seria mais apropriado a setores de alta intensidade tecnológica. Conclui-se que o método de Olley e Pakes é levemente superior ao de Levinsohn e Petrin em ambos os grupos de setores, mas não a ponto de se descartar o segundo método. A sensibilidade dos resultados aos diferentes métodos sugere que todos devem ser consultados. Um resultado adicional deste trabalho é a constatação de que houve queda ou estagnação da produtividade nos setores selecionados para a década de 1996 a 2005.

Environmental policy and growth when inputs are differentiated in pollution intensity

Environmental policy affects the distribution of market shares if intermediate goods are differentiated in their pollution intensity. When innovations are environment-friendly, a tax on emissions skews demand towards new goods which are the most productive. In this case, the tax has to increase along a balanced growth path to keep the market shares of goods of different vintages constant. Comparing balanced growth paths, we find that an increase in the burden of environmental taxation spurs innovation because it increases the market share of recent vintages. As a result the cost of environmental policy in terms of slower growth is weaker and may even be absent.

Sources of comparative advantages in Brazil

Based on the Heckscher-Ohlin-Vanek model, this paper investigates relative factor abundance in Brazil, as revealed by its international trade. We study two different time periods: one characterized by high trade barriers (1980 to 1985) and the trade liberalization period (1990 to 1995). Two alternative methodologies are used: the estimation of factor intensity regressions on net exports and the direct computation of factor content in net exports. In the factor intensity regression, we incorporate technological changes that might have occurred over time, and those turned out to be significant. Both methods yield the same results: the Brazilian international trade reveals relative abundance in capital, land and unskilled labor, and scarcity in skilled labor, with qualitatively equivalent results for the two time periods studied.

Development, technological change and innovation, Schumpeter and neo-Schumpeterians

This review essay is devoted to a discussion of some central aspects of the Schumpeterian and neo-Schumpeterian approaches to the dynamic processes of development, technological change and innovation. This essay is organised in two parts. In the first, Schumpeter's insightful distinction between circular flow and development is discussed. In the second, some central elements of the neo-Schumpeterian interpretation and extension of Schumpeter's views are critically outlined, special emphasis being placed on some recent attempts to formalize several of his insights on the cyclical dynamics of the processes of technological change and innovation. I should stress that due to space constraints I will focus primarily upon macrotheoretic issues, thus paying only secondary attention to the neo-Schumpeterian literature on the microeconomics of technological change and to the burgeoning empirical developments along those lines.

Endogenous growth with deferred technological change

Lucas (2009) propôs um modelo com dois setores para explicar padrões observados em dados de crescimento. Entretanto, a análise de Lucas não envolve uma decisão intertemporal para o consumidor. O comportamento das variáveis é determinado à priori pela tecnologia escolhida. Rodriguez (2006) propôs um modelo com a tecnologia com dois setores apresentada por Lucas adicionando um processo de decisão intertemporal para o consumidor. Adicionalmente aos resultados obtidos por Rodriguez, nós caracterizamos suficiência e apresentamos exemplos esclarecedores de casos particulares do modelo. Ademais, nós fazemos um esforço para derivar novos insights e esclarecer alguns pontos técnicos. Finalmente, nós obtemos condições sob as quais a economia investe em capital humano mesmo com benefícios diferidos.

Reestruturação produtiva e terciarização

A pesquisa examina os aspectos teóricos e empíricos relacionados ao movimento de reestruturação produtiva das economias e as implicações sobre o processo de terciarização verificado na atualidade tanto em países avançados quanto nos menos desenvolvidos. O estudo parte de uma base teórica que inclui como condicionantes da intensificação dessa reestruturação e terciarização o crescente processo de globalização econômica, o aumento da intensidade e da velocidade do progresso tecnológico, bem como a necessidade do enfrentamento de uma situação conjuntural recessiva. Foi examinada empiricamente a realidade brasileira em um período histórico a partir dos anos 70.

Implicações dos processos de aprendizagem para acumulação de competências tecnológicas: reflexões sobre a experiência da Cyanamid Indústria Química em Resende, RJ

Esta dissertação examina o relacionamento entre os processos subjacentes de aprendizagem e acumulação de competências tecnológicas na Cyanamid Indústria Química, maiS especificamente em sua fábrica localizada no município de ResendelRJ. Este estudo trata do período entre 1990 e 1999. E enfocou a acumulação de competências para três funções tecnológicas: investimentos, processos e organização da produção e equipamentos. Os quatro processos de aprendizagem: aquisição externa e interna, socialização e codificação de conhecimento são examinados à luz de quatro características chaves: variedade, intensidade, funcionamento e interação. Para esta análise foram utilizadas estruturas existentes na literatura de empresas em industrialização e literatura de empresas de tecnologia de fronteira. A conclusão desta dissertação sugere que os processos de aprendizagem contribuíram substancialmente para acumulação de competências tecnológicas na empresa em estudo. Quanto maior à importância destes processos de aprendizagem e de suas quatro características chaves: variedade, intensidade, funcionamento e interação, maior será a capacidade e velocidade de acumulação de competências tecnológicas. Este trabalho também sugere que esta acumulação foi influenciada por outros fatores externos e internos como: políticas governamentais e comportamento da liderança, apenas para citar alguns. Estes fatores externos e internos estão alem do escopo desta dissertação. Esta conclusão não é diferente de estudos anteriores, mas concentra-se em refletir sobre um estudo aplicado a uma indústria ainda não examinada pela literatura existente de empresas em industrialização. Em especial, sobre uma experiência individual, localizada no interior do estado do Rio de Janeiro.

Acumulação de competências tecnológicas e os processos subjacentes de apredizagem: o caso da Invensis Appliances Controls Unidade Vacaria - RS

Esta dissertação enfoca o relacionamento entre acumulação de competências tecnológicas e os processos subjacentes de aprendizagem. Este relacionamento é examinado na empresa Invensys Appliance Controls Ltda. - Unidade de Vacaria/RS, durante o período de 1981 a 2000. Trata-se de uma empresa metal-mecânica, fornecedora da indústria de linha branca. Em outras palavras, a dissertação examina as implicações dos processos subjacentes de aprendizagem tecnológica para a acumulação de competências para três funções tecnológicas: processo e organização da produção, produtos e equipamentos. Os processos de aprendizagem são examinados à luz de quatro características: variedade, intensidade, funcionamento e interação, a partir do uso de estruturas de análise existente na literatura. Baseado em estudo de caso individual, este estudo encontrou que a maneira e a velocidade de acumulação de competências tecnológicas na empresa estudada estão associadas aos diversos processos usados para adquirir conhecimento tecnológico e convertê-lo em organizacional. Ademais, a simples incidência desses processos na empresa não garantiu na empresa uma implicação positiva para a acumulação de competências tecnológicas. Através do uso de estrutura existente na literatura, porém aplicada a uma indústria diferente de estudos anteriores, esta dissertação sugere que deve existir um esforço organizado, contínuo e integrado para geração e disseminação de conhecimento em toda a empresa a fim de que a acumulação de capacitação tecnológica seja acelerada na empresa.

Acumulação de competências tecnológicas e processos de aprendizagem : o caso aciaria da Companhia Siderúrgica Nacional

This work is focused on the explanation of the relation between the learning processes, the accumulation of technological competence and the competitive performance. The present study is based on the case of the steelmaking plant of Companhia Siderúrgica Nacional, located in Volta Redonda city, Rio de Janeiro state, Brazil, during the period of 1997 and 2001. The framework of this thesis is based on Figueiredo (2001), that shares the learning process in external and internal acquisition of knowledge, and the conversion of this knowledge from people to organization through socialization (transfer of tacit knowledge) or codification (transfer of knowledge by written documents). This framework considers the key features of the learning process: the variety, the intensity, the working and the interaction. The results suggest that the steelmaking of CSN achieved the pre intermediate level (level 4) of technological competence to the technological functions of production process and equipment, and the intermediate level (level 5) to the function product. The accomplishment of these levels of competence was due to the acquisition and conversion of new knowledge. It was observed that the key features had an evolution during the period considered in the study. The results allowed to show that the accumulation of technological competence had a positive influence over the competitive performance of the steelmaking unit of CSN.

Trajetórias De Acumulação De Capacidades Inovadoras, Mecanismos De Aprendizagem E Fatores Organizacionais Relativos A Atividades Em Gestão De Projetos: Estudo De Caso Comparativo Inter-Empresarial Na Indústria De Bens De Capital E De Celulose E Papel No Brasil

Over the last 40 years there has been a profusion of studies about the ccumulation of technological capacities in firms from developing economies. However, there remain few studies that examine, on a combined basis, the relationship among: the trajectories of technological capacities accumulation; the underlying learning mechanisms; and, the implications of organizational factors for these two variables. Still scarcer are the studies that examine the relationship among these variables along time and based on a comparative case study. This dissertation examines the relationship among the trajectory of accumulation of innovative capacities in complex project management, the learning mechanisms underlying these technological capacities and the intra-organizational factors that influence these learning echanisms. That set of relationships is examined through a comparative and a long-term (1988-2008) case study in a capital goods firm (for the pulp and paper industry) and a pulp mill in Brazil. Based on first-hand quantitative and qualitative empiric evidence, gathered through extensive field research, this dissertation found: 1. Both firms accumulated innovative capacity in project management at the international frontier level (Level 6). However, there was variability between the firms in terms of the nature and speed of accumulation of those capacities. It was also observed that, at this level of innovation, the innovative capacities of both firms are not confined to their organizational boundaries, but they are distributed beyond their boundaries. 2. So that these companies could accumulate those levels of innovative capacities it was necessary to manage several learning mechanisms: leveraging of external knowledge and its internalization in terms of internal apacities of the firm. In other words, as the companies accumulated more innovative levels of capacities for project management, it was necessary to manage different cycles of technological learning. 3. Further, the relationship between the ccumulation of technological capacities and learning was affected positively by intra-organizational factors, such as 'authority disposition', 'mutability of work roles' and 'intensity of internal crises', and negatively by the factor 'singularity of goals'. This dissertation revealed divergent results between firms in two of the four factors studied. These results contribute to advance our understanding of the complexity and variability involved in the process of accumulation of innovative capacities in firms from developing economies. This highlights the growing importance of the organizational and the human resource dimensions of innovation and technological capacity as the company approaches the international frontier. The results suggest to managers that: (i) the good performance in project management in the two firms studied did not occur simply as a result of the pulp and paper Brazilian industry growth, rather as a result of the deliberate construction and accumulation of the capacities through an intensive and coordinated cyclical process of technological learning, (ii) to develop innovative capabilities in project management, besides looking for learning mechanisms they should also look at the organizational factors that influence the learning mechanisms directly, (iii) performance of pulp mill¿s projects is better when projects are implemented together with technology suppliers than when performed only by the mill. This dissertation concludes that capital goods firms have been having a fundamental role for the innovative capabilities accumulation in project management of pulp mills in Brazil (and vice-versa) for a long time. This contradicts some authors' propositions that affirm that: a) equipment suppliers for the pulp and paper industry have been creating little, if any, development of processes or engineering projects in Brazil; b) firms in the pulp and paper industry have little capacity for machinery and equipments projects only taking place in few technological activities, being internal or external to the firm. Finally, some studies are proposed for future research.

Acumulação de competências tecnológicas e os processos subjacentes de aprendizagem na indústria Mmtal - mecânica : o caso da empresa AGCO comércio e indústria LTDA em Santa Rosa - RS

This dissertation enfoca the relationship between technological competences accumulation and the learning underlying processes. This relationship is examined in the company AGCO Comércio and Indústria Ltda, during the period of 1970 to 2000. It is of a company metal-mechanics, agricultural machines manufacturer. In other words, the dissertation examines the processes technological learning implications for aA technological competences accumulation in the company in study. The dissertation enfoca the competences accumulation for three technological functions: processes and organization, products and equipments. The learning processes are examined to the light of four characteristic: variety, intensity, operation and interaction, from the structure existing analysis use in the literature. Based on study of individual case, this study found that the technological competences ways to accumulation in the studied company are associates to the several processes used to acquire technological knowledge and converts him in organizacional. Ademais, the simple incidence of these processes in the company didn't guarantee in the company a positive implication for the technological competences accumulation. The company accumulated level middleman-superior technological competence (level 6) to accomplish production and function products function processes and organization activities, and intermediary level (level 5) to accomplish function equipments activities. In haves to characteristic key, the learning processes introduce an oscillation differentiated along time: the variety oscillated of moderated the several; the intensity of intermittent the continuous; the operation of bad the good; and the interaction of weak the strong. Through the existing structure use in the literature, however applied to a previous studies different industry, this dissertation suggests that must there be an organized , continuous effort and integrated for the knowledge generation and sowing in every company in order to the technological training accumulation be accelerated in the company.

Acumulação de competências tecnológicas e os processos subjacentes de aprendizagem na indústria de bens de capital: O caso KVAERNER PULPING no Brasil

This dissertation is concerned with the implications of the learning processes for the technological capability accumulation at the firm level. This relationship was examined in Kvaerner Pulping over the period from 1980 to 2000. The firm is located in Curitiba/PR and supplies equipment and complete plants (capital goods) for pulp mills. In other words, based on an individual case study, this dissertation examines how the learning processes influence the building and accumulation of technological capability. The accumulation of technological capabilities is crucial for the survival and the competitive performance of the firms. An analytical framework already available in the literature was used to describe the paths (way and speed) of technological capability accumulation in the firm studied. However, the framework was adapted specifically for the capital goods industry for the pulp & paper sector. The paths of technological capability accumulation are analysed for three different technological functions: ¿engineering activities and project management¿, ¿operational processes and practices¿ and ¿process equipment¿. The learning mechanisms were examined in the light of four key features: variety, intensity, functioning and interaction. During the 1980s and 1990s the firm accumulated different levels of technological capability in the technological functions studied. It was only when the firm started to coordinate systematically the efforts to acquire and convert the knowledge from the individual to the organizational level, at the mid 1990s, that the accumulation of technological capability was accelerated. By the end of this decade the firm was able to accumulate innovative capabilities in all the functions analysed. Similarly to previous studies that investigated other types of firms, the conclusion of this dissertation suggests that the way and rate by which the firm accumulates technological capability can be explained by the learning process and its key features over time.

Acumulação de competências tecnológicas e os processos subjacentes de aprendizagem na indústria eletrônica de consumo : o caso da SHARP do Brasil S/A

Esta dissertação estuda o relacionamento entre a acumulação de competências tecnológicas e os processos subjacentes de aprendizagem. O estudo desse relacionamento foi examinado na fábrica de eletrônica de consumo Sharp do Brasil S/A, situada na cidade de Manaus, durante o período de 1972 a 2000. A acumulação e sustentação de competências tecnológicas são desenvolvidas através de processos de aprendizagem nas organizações. Os processos de aprendizagem estão relacionados diretamente à taxa de acumulação de competências tecnológicas das organizações. A dissertação, utilizando a estrutura de análise existente na literatura, examina os processos de aprendizagem à luz de quatro características: variedade, intensidade, funcionamento e interação. A acumulação de competências é analisada a partir de duas funções tecnológicas: processo/organização e produtos. Ao longo do periodo analisado, a empresa acumulou diferentes níveis de competências tecnológicas e com velocidades variadas nas funções estudadas. Na década de 80, a empresa através de uma melhor coordenação de esforços, passou a adquirir e converter conhecimentos individuais em conhecimentos organizacionais, acelerando o crescimento da taxa de competências tecnológicas acumuladas. Ainda no final da década 80, a empresa foi capaz de acumular competências inovadoras nas duas funções estudadas. A acumulação de competências tecnológicas é um aspecto importante a competitividades e sobrevivência das organizações. No entanto, somente a acumulação de competências tecnológicas não garante o bom desempenho e a sobrevivência da organização. A empresa estudada, apesar da acumulação de elevados níveis de competências tecnológicas ao longo do periodo, enfrenta uma grande crise financeira. A conclusão desta dissertação sugere que a taxa de acumulação de competências tecnológicas pode ser explicada pela capacidade da empresa em socializar e codificar a aprendizagem individual, adquiridas por processos externos e internos de aprendizagem aplicados de forma contínua e organizada, convertendo em aprendizagem organizacional.

Comportamento dos processos intra-organizacionais de aprendizagem tecnológica frente a uma mudança de estrutura de propriedade: o caso da TermoMacaé - PETROBRÁS

This academic work describes the interfirm technological learning processes behavior at a thermo plant throughout the years 2001 till 2007. Its former ownership structure was composed by two foreigners companies. This structure was changed by the acquisition of the company control by a Brazilian state owned company on April 2006. The company is a Natural Gas Fired Power Plant placed at Macaé City, at Rio de Janeiro State, Brazil generating electric power right to National Integrated System (SIN). The goal of this research is verify how the technological knowledge had been acquired by the firm and how it had been spread out throughout the organization before and after the change of the ownership structure. The taxonomy applied to determining of ownership structure take in account three parameters: type, specific characteristic and the ownership structure itself. Technological Learning Interfirm Processes have been examined from a model of systemic approach that establishes four key characteristics: ¿variety, intensity, functioning and interaction¿. During 2001 until 2006, till the change of owner structure, the firm developed its own learning processes in its own operational routines. The main learning processes have been identified from empirical evidences. It has been adopted the cut line at year of 2006 for the comparison among the technological learning processes behavior, when the change of ownership structure took place. The data capture occurred within April and August 2007 covering since 2001. Verified the behavior of these learning processes before and after the ownership structure changed from private property to state owned property. The conclusion of this case study suggests that interfirm processes of technological learning identified by the research had their dynamical behavior promptly affected by a change from private to ownerstate ownership structure, exposing the company to a poor performance in its industry, due to the lack of 51% of the technological intrafirm learning processes and reduction of the acquisition of new technical knowledge and its conversion throughout the organization.

Acumulação de competências tecnológicas em processos e produtos e aprendizagem tenológica: o caso da ELETROLUX do Brasil S/A - Unidade de Guabirotuba - Curitiba/PR

This dissertation is concerned with the implications of the learning process on the technological capabilities accumulation. This relationship was examined at the Electrolux do Brasil S/A ¿ Guabirotuba Unity ¿ in Curitiba/PR, over the period of 1980 to 2000. The Brazilian factory products White Goods destined to the Brazilian market as well as to exportation. The Swedish group Electrolux, to which the Brazilian factory belongs to, produces and sell goods to more then 150 countries. Regardless their importance, studies on the accumulation of technological capabilities and the underlying learning process are still scarce in Brazil, especially those focusing on the eletrodomestics products, and more specifically on the refrigerators and freezers industry. Based on a case study in the Electrolux do Brasil S/A, from 1980 to 2000, this investigation examined the influence of the learning process in the paths of the technological capabilities accumulation in the firm. The learning processes were analyzed in the light of the analytical framework proposed by Figueiredo (2001). This framework consists in four key features: variety, intensity, functioning and interaction. The technological capabilities accumulation were studied considering two technological functions: Process and Production Organization Activities and Products Activities. The evidences to classify and describe the paths of technological capabilities accumulation as well as to analyse the learning were mainly qualitative. This investigation joins other previous studies, in which there was noticed that the learning process have great involvement on technical changes, playing a relevant role on the technological capabilities of a company. Based on the investigation done and on the practical utilization of the analytical structure proposed by Figueiredo (2001), we infer that the way and the speed of technological capabilities accumulation are related to how the various learning processes were used by the company. One implied that, in levels from one to six, the studied company cumulated capabilities to level (5). Regarding technological competence, it approached industrialized countries firms, which present level (6), advanced.
