Los conceptos de salud financiera, riesgo y epidemiología en los estados financieros de las compañías del sector de extracción de petróleo crudo y gas natural en Colombia

El presente proyecto tiene como objeto identificar cuáles son los conceptos de salud, enfermedad, epidemiología y riesgo aplicables a las empresas del sector de extracción de petróleo y gas natural en Colombia. Dado, el bajo nivel de predicción de los análisis financieros tradicionales y su insuficiencia, en términos de inversión y toma de decisiones a largo plazo, además de no considerar variables como el riesgo y las expectativas de futuro, surge la necesidad de abordar diferentes perspectivas y modelos integradores. Esta apreciación es pertinente dentro del sector de extracción de petróleo y gas natural, debido a la creciente inversión extranjera que ha reportado, US$2.862 millones en el 2010, cifra mayor a diez veces su valor en el año 2003. Así pues, se podrían desarrollar modelos multi-dimensional, con base en los conceptos de salud financiera, epidemiológicos y estadísticos. El termino de salud y su adopción en el sector empresarial, resulta útil y mantiene una coherencia conceptual, evidenciando una presencia de diferentes subsistemas o factores interactuantes e interconectados. Es necesario mencionar también, que un modelo multidimensional (multi-stage) debe tener en cuenta el riesgo y el análisis epidemiológico ha demostrado ser útil al momento de determinarlo e integrarlo en el sistema junto a otros conceptos, como la razón de riesgo y riesgo relativo. Esto se analizará mediante un estudio teórico-conceptual, que complementa un estudio previo, para contribuir al proyecto de finanzas corporativas de la línea de investigación en Gerencia.

Reflexiones economicistas sobre la izquierda y la derecha

Este documento está compuesto por cuatro secciones de las cuales esta introducción es la primera. En la segunda sección se analiza la visión que diferentes individuos pueden tener acerca del problema de la desigualdad y las implicaciones que estas diferencias tienen sobre el ideal de política re-distributiva. En la tercera sección se presenta una revisión analítica de la literatura económica que se ocupa de las relaciones entre distribución del ingreso y crecimiento económico. Finalmente, en la última sección se presentan algunas conclusiones.

Why labor income shares seem to be constant?

The common assumptions that labor income share does not change over time or across countries and that factor income shares are equal to the elasticity of output with respect to factors have had important implications for economic theory. However, there are various theoretical reasons why the elasticity of output with respect to reproducible factors should be correlated with the stage of development. In particular, the behavior of international trade and capital flows and the existence of factor saving innovations imply such a correlation. If this correlation exists and if factor income shares are equal to the elasticity of output with respect to factors then the labor income share must be negatively correlated with the stage of development. We propose an explanation for why labor income share has no correlation with income per capita: the existence of a labor intensive sector which produces non tradable goods.

When innovation becomes inefficient: reexamining Britain's radio industry

I examine the factors underpinning the British radio-equipment sector's particularly poor interwar productivity performance relative to the United States. Differences in socio-legal environments were crucial in allowing key players in the British industry to derive higher monopoly rents than their American counterparts. Higher British rents in turn, had the unintended outcome of stimulating innovation around restrictive patents, initiating a path-dependent process of technical change in favor of expensive multifunctional valves. These valves both raised direct production costs and prevented British firms from following the American path of broadening the radio market beyond the household's prime receiver.

Productivity of nations: a stochastic frontier approach to TFP decomposition

This Paper Tackles the Problem of Aggregate Tfp Measurement Using Stochastic Frontier Analysis (Sfa). Data From Penn World Table 6.1 are Used to Estimate a World Production Frontier For a Sample of 75 Countries Over a Long Period (1950-2000) Taking Advantage of the Model Offered By Battese and Coelli (1992). We Also Apply the Decomposition of Tfp Suggested By Bauer (1990) and Kumbhakar (2000) to a Smaller Sample of 36 Countries Over the Period 1970-2000 in Order to Evaluate the Effects of Changes in Efficiency (Technical and Allocative), Scale Effects and Technical Change. This Allows Us to Analyze the Role of Productivity and Its Components in Economic Growth of Developed and Developing Nations in Addition to the Importance of Factor Accumulation. Although not Much Explored in the Study of Economic Growth, Frontier Techniques Seem to Be of Particular Interest For That Purpose Since the Separation of Efficiency Effects and Technical Change Has a Direct Interpretation in Terms of the Catch-Up Debate. The Estimated Technical Efficiency Scores Reveal the Efficiency of Nations in the Production of Non Tradable Goods Since the Gdp Series Used is Ppp-Adjusted. We Also Provide a Second Set of Efficiency Scores Corrected in Order to Reveal Efficiency in the Production of Tradable Goods and Rank Them. When Compared to the Rankings of Productivity Indexes Offered By Non-Frontier Studies of Hall and Jones (1996) and Islam (1995) Our Ranking Shows a Somewhat More Intuitive Order of Countries. Rankings of the Technical Change and Scale Effects Components of Tfp Change are Also Very Intuitive. We Also Show That Productivity is Responsible For Virtually All the Differences of Performance Between Developed and Developing Countries in Terms of Rates of Growth of Income Per Worker. More Important, We Find That Changes in Allocative Efficiency Play a Crucial Role in Explaining Differences in the Productivity of Developed and Developing Nations, Even Larger Than the One Played By the Technology Gap

Três ensaios sobre o gasto local no Brasil: descentralização, eficiência e voto

Partindo de uma avaliação sobre o contexto mundial de descentralização fiscal e de democratização em que o Brasil se encontrava no final do século XX, essa tese apresenta na primeira parte uma análise empírica para países em desenvolvimento evidenciando o condicionamento do tipo de regime de governo na relação entre descentralização fiscal e tamanho de governo. Estimações por system-GMM para países em desenvolvimento mostram que existe um nível de descentralização fiscal, entre 20% e 30%, que uma vez superado, resulta em democracias com tamanhos de governos menores do que as ditaduras. Esses resultado, que chama a atenção tanto para os governos locais, como para a influência da democracia no gasto público, estimulou a continuação da pesquisa na avaliação da eficiência dos gastos municipais no Brasil e sua relação com o voto. Assim, no segundo ensaio, são calculados indicadores de evolução da eficiência e da produtividade do gasto municipal (fatores de Malmquist) entre 2004 e 2008, para as áreas da saúde e educação. Os resultados da análise por fronteira estocástica mostram que tanto na educação, como na saúde, houve avanços na fronteira de produção (TFPC, em média, de 18.7%, na educação e de 14.2% na saúde) por avanços de mudança técnica (Technical Change - TC), ao invés de elevação da eficiência (Technical Efficiency Change – TEC). No último ensaio, os indicadores de eficiência e de produtividade são usados para testar a hipótese de que o eleitor municipal premia com o voto os prefeitos que melhoraram a eficiência do gasto da educação e/ou saúde em sua gestão. Os resultados não rejeitam a hipótese para a educação, mas rejeitam para a saúde. A fim de tratar prováveis erros de medida das variáveis de produtividade, as estimações são instrumentalizadas em regressões por dois estágios.

Understanding e-government technology transfer: evidence from the transfer of a patent management system from EPO to INPI

Drawing upon Brazilian experience, this research explores some of the key issues to be addressed in using e-government technical cooperation designed to enhance service provision of Patent Offices in developing countries. While the development of software applications is often seen merely as a technical engineering exercise, localization and adaptation are context bounded matters that are characterized by many entanglements of human and non-humans. In this work, technical, legal and policy implications of technical cooperation are also discussed in a complex and dynamic implementation environment characterized by the influence of powerful hidden agendas associated with the arena of intellectual property (IP), which are shaped by recent technological, economic and social developments in our current knowledge-based economy. This research employs two different theoretical lenses to examine the same case, which consists of transfer of a Patent Management System (PMS) from the European Patent Office (EPO) to the Brazilian Patent Office that is locally named ‘Instituto Nacional da Propriedade Industrial’ (INPI). Fundamentally, we have opted for a multi-paper thesis comprising an introduction, three scientific articles and a concluding chapter that discusses and compares the insights obtained from each article. The first article is dedicated to present an extensive literature review on e-government and technology transfer. This review allowed the proposition on an integrative meta-model of e-government technology transfer, which is named E-government Transfer Model (ETM). Subsequently, in the second article, we present Actor-Network Theory (ANT) as a framework for understanding the processes of transferring e-government technologies from Patent Offices in developed countries to Patent Offices in developing countries. Overall, ANT is seen as having a potentially wide area of application and being a promising theoretical vehicle in IS research to carry out a social analysis of messy and heterogeneous processes that drive technical change. Drawing particularly on the works of Bruno Latour, Michel Callon and John Law, this work applies this theory to a longitudinal study of the management information systems supporting the Brazilian Patent Office restructuration plan that involved the implementation of a European Patent Management System in Brazil. Based upon the ANT elements, we follow the actors to identify and understand patterns of group formation associated with the technical cooperation between the Brazilian Patent Office (INPI) and the European Patent Office (EPO). Therefore, this research explores the intricate relationships and interactions between human and non-human actors in their attempts to construct various network alliances, thereby demonstrating that technologies embodies compromise. Finally, the third article applies ETM model as a heuristic frame to examine the same case previously studied from an ANT perspective. We have found evidence that ETM has strong heuristic qualities that can guide practitioners who are engaged in the transfer of e-government systems from developed to developing countries. The successful implementation of e-government projects in developing countries is important to stimulate economic growth and, as a result, we need to understand the processes through which such projects are being implemented and succeed. Here, we attempt to improve understanding on the development and stabilization of a complex social-technical system in the arena of intellectual property. Our preliminary findings suggest that e-government technology transfer is an inherently political process and that successful outcomes require continuous incremental actions and improvisations to address the ongoing issues as they emerge.

What kind of microfoundations? Notes on the evolutionary approach

The microfoundations of economic models are a hotly debated topic in the literature. The debate is important because microfoundations —the ways in which agents decide and behave— have implications that go beyond a specific firm, market or activity; they strongly condition macroeconomic outcomes. This document addresses the classical problems of rationality, uncertainty and institutions: when there is Keynes-Knight uncertainty and rationality is bounded, decision making adopts the form of conventional rules or heuristics. The hyper-rational representative agent of the rational expectations world could generate highly misleading outcomes in macro models. Section 2 applies this discussion to the study of technical change and to innovation and diffusion of technology in the international system, which transform the patterns of specialization. Section 3 discusses the forces that may trap a country in a low-growth trap and the crucial role of institutions in escaping from this trap.

O pólo industrial de Manaus como modelo de desenvolvimento econômico avaliado sob o enfoque da Lei de Kaldor-Verdoorn

Este estudo tem como objetivo mensurar e avaliar a dinâmica econômica do Pólo Industrial de Manaus como um modelo de desenvolvimento sob o enfoque da Lei de kaldor-Verdoorn. Especificamente, analisar a relação entre produção e produtividade, sob as condições preconizadas por esta lei, aplicadas às indústrias do Pólo Industrial de Manaus. A Lei de Kaldor-Verdoorn propõe que à medida que a produção aumenta, há uma forte tendência, ao longo do tempo, de crescimento da produtividade. Economias de escala são geradas endogenamente por mudança técnica e aprendizagem tecnológica (learning by doing), fruto do crescimento da demanda que permite que se explore as economias de escala dinâmicas presentes, principalmente, no setor manufatureiro. Dessa forma, estima-se a produtividade total de fatores e a produtividade parcial. Analisa-se a dinâmica dessa economia efetuando-se teste empírico para a indústria do Pólo Industrial de Manaus, no período de janeiro de 1995 a dezembro de 2004, através de um modelo de correção de erros, teste de causalidade de Granger e modelo VAR estrutural,. Os resultados obtidos indicam um razoável grau de dinamismo dessa economia, dado que a combinação de efeitos de curto e longo prazo fez com que a produtividade crescesse num ritmo mais acelerado, com respostas rápidas no curto prazo, da produtividade a choques de mudanças no valor total da produção e emprego. Comprovam também a existência de fontes endógenas de crescimento da produtividade, evidenciando economias de escala crescente.
