Identificación de escenarios a futuro para lograr competitividad en el sector de telefonía móvil en Colombia al año 2020

Este trabajo pretende explorar el desarrollo del sector de la telefonía móvil desde sus inicios hasta la actualidad en Colombia, con el fin de generar escenarios de futuro. Las herramientas prospectivas MicMac (Análisis Estructural Prospectivo), Smic (Sistema de Matrices de Impactos Cruzados) y la opinión de expertos líderes del sector, son la base principal para el desarrollo del trabajo. Las entidades gubernamentales, la CTR (Comisión de Regulación de Telecomunicaciones), y los líderes de los operadores del sector de telefonía móvil, entre otros, se han concientizado que la innovación es la base del éxito en este tipo de organizaciones y por eso se ha trabajado en mejorar su regulación, logrando de esta manera que el desarrollo de los productos y servicios que se ofrecen sean cada vez mejores y perjudique en menor medida al medio ambiente y a los usuarios. Este subsector de las telecomunicaciones, es el más dinámico y con mayor potencial. Sin embargo, este también es afectado por las condiciones económicas del mercado, la inestabilidad política, las importaciones y exportaciones derivadas de los tratados comerciales, entre otros temas. El escenario apuesta facilitaría la prestación de productos con tecnología de punta y servicios con la mejor cobertura y acceso posible a precios bajos.

Optimal growth in a two-sector model without discounting: a geometric investigation

We characterize optimal policy in a two-sector growth model with xed coeÆcients and with no discounting. The model is a specialization to a single type of machine of a general vintage capital model originally formulated by Robinson, Solow and Srinivasan, and its simplicity is not mirrored in its rich dynamics, and which seem to have been missed in earlier work. Our results are obtained by viewing the model as a specific instance of the general theory of resource allocation as initiated originally by Ramsey and von Neumann and brought to completion by McKenzie. In addition to the more recent literature on chaotic dynamics, we relate our results to the older literature on optimal growth with one state variable: speci cally, to the one-sector setting of Ramsey, Cass and Koopmans, as well as to the two-sector setting of Srinivasan and Uzawa. The analysis is purely geometric, and from a methodological point of view, our work can be seen as an argument, at least in part, for the rehabilitation of geometric methods as an engine of analysis.

Dimensions of the third sector : comparative perspectives on structure and change

Cross-nationally, the introduction of New Public Management coincides with a significant growth phase of the nonprofit or third sector. This growth has disproportionately been an expansion of the economic dimensions (employment, turnover) and basically involved the greater use of third sector organisations as service providers. Such provision uses complex contract regimes, and typically takes place in some form of public-private partnership with either public or private funding agencies. Other parts of the third sector such as membership, volunteering and giving have generally grown less. The paper suggests that the sector is becoming qualitatively different, although the nature and strength of this change depends on the nonprofit regime type in a given country. Generally, however, third sector growth has led to differentiation processes that involve new organisational forms, and changes in activities and overall composition. The paper explores the measurement aspects of the quantitative-qualitative jump in third sector development by trying to "map" changes in core facts or dimensions over time. In closing, the paper suggests to examine recombination and refunctionality processes in the third sector.

Transformation in educational practices through STEM

The need for strong science, technology and innovation linkages between Higher Education Institutions (HEIs) and industries is a pivotal point for middle-income countries in their endeavor to enhance human capital in socioeconomic development. Currently, the University-Industry partnerships are at an infant stage in Sri Lankan higher education context. Technological maturity and effective communication skills are contributing factors for an efficient graduate profile. Also, expanding internship programs in particular for STEM disciplines provide work experience to students that would strengthen the relevance of higher education programs. This study reports historical overviews and current trends in STEM education in Sri Lanka. Emphasis will be drawn to recent technological and higher education curricular reforms. Data from the last 10 years were extracted from the higher education sector and Ministry of Higher Education Policy portfolios. Associations and trend analysis of the sector growth were compared with STEM existence, merger and predicted augmentations. Results were depicted and summarised based on STEM streams and disciplines. It was observed that the trend of STEM augmentation in the Sri Lankan Higher Education context is growing at a slow but steady pace. Further analysis with other sectors in particular, Industry information, would be useful and a worthwhile exercise.

Negociar direitos? : legislação trabalhista e reforma neoliberal no governo FHC (1995-2002)

Ao longo do século XX, o Direito do Trabalho esteve associado a um arranjo político e social cujos sentidos estavam vinculados, entre outros aspectos, à civilização das relações de classe e à reprodução do capitalismo com democracia, no âmbito dos Estados nacionais. O propósito desta pesquisa é investigar como ocorreu o processo de deslocamento e reinterpretação desses sentidos (equivalente à codificação da razão do mais forte), no contexto da forte hegemonia política da coalizão de centro-direita que governou o país entre 1995 e 2002. Nesse período, o Poder Executivo Federal, as principais organizações patronais, setores importantes da mídia impressa e a Força Sindical estiveram empenhados na promoção de profunda alteração dos traços centrais do modelo brasileiro de relações de trabalho, no qual a lei é mais importante na definição dos direitos substantivos do trabalho do que os contratos coletivos. Para justificar politicamente essas alterações, o Poder Executivo e seus apoiadores apontaram a responsabilidade do modelo legislado pelos elevados custos do emprego formal, a perda de competitividade da indústria, o aumento da informalidade e do desemprego durante o governo FHC. Por meio da leitura das justificativas dos projetos encaminhados ao Congresso Nacional pelo Poder Executivo, das manifestações de suas principais lideranças e dos apoiadores na mídia e no meio sindical, a pesquisa busca interpretar o sentido político dessa leitura, apresentada como se fosse solução técnica e modernizante para uma legislação que estaria ultrapassada. Consideramos que a reforma trabalhista tinha claros propósitos políticos pois, além de repassar aos trabalhadores os custos do ajuste econômico nos anos 90, permitiu justificar na cena pública a retração do papel do Estado, bem como fortalecer o apoio de setores importantes do patronato a esse projeto político.

Hicks meets Hotelling: the direction of technical change in capital-resource economies

We analyze a two-sector growth model with directed technical change where man-made capital and exhaustible resources are essential for production. The relative profitability of factor-specific innovations endogenously determines whether technical progress will be capital- or resource-augmenting. We show that any balanced growth equilibrium features purely resource-augmenting technical change. This result is compatible with alternative specifications of preferences and innovation technologies, as it hinges on the interplay between productive efficiency in the final sector, and the Hotelling rule characterizing the efficient depletion path for the exhaustible resource. Our result provides sound micro-foundations for the broad class of models of exogenous/endogenous growth where resource-augmenting progress is required to sustain consumption in the long run, contradicting the view that these models are conceptually biased in favor of sustainability.

Income ineqaulity from 1960-2012: a brief time-series history of capital and labour

This commentary examines two principal forms of inequality and their evolution since the 1960s: the division of national income between capital and labour, and the share of total income held by the top 1 per cent of earners. Trends are linked to current discussions of inequality drivers such as financialisation, and a brief time-series analysis of the effects of trade and financial sector growth on top incomes is presented.

Diferencial de salários e produtividade no setor de serviços brasileiro

This paper provides new information about inter-industry wage di§erentials in Brazil. Using data from the National Survey Sample of Households, we can see that from 1983 to 1995 the relative average wage of the service sector compared to the goods sector decreased, whereas from 1995 to 2007 it increased at a higher level than the previous decrease. After controlling for a variety of work characteristics, we can still see the positive evolution of rel- ative ages in the service sector. We conclude that this development has some explanations: the period of economic growth and stabilization that started after 1994 generated a positive income e§ect, and the service sector beneÖted more from it. Also, the structural transfor- mation that the developed countries already went through still hasn¥t Önished in Brazil. That probably helped improving relative wages in the service sector and it¥s expected the continuation of this process, so as the structural transformation evolves inter-industry wage di§erentials will converge.

Trade policy in a dynamic Heckscher-Ohlin model

The Import Substitution Process in Latin Amer ica was an attempt to enhance GDP growth and productivity by rising trade barriers upon capital-intensive products. Our main goal is to analyze how an increase in import tariff on a particular type of good affects the production choices and trade pattern of an economy. We develop an extension of the dynamic Heckscher-Ohlin model – a combination of a static two goods, two-factor Heckscher-Ohlin model and a two-sector growth model – allowing for import tariff. We then calibrate the closed economy model to the US. The results show that the economy will produce less of both consumption and investment goods under autarky for low and high levels of capital stock per worker. We also find that total GDP may be lower under free trade in comparison to autarky.
