Energía Eólica en Argentina: una cuestión estratégica hacia la Economía del Hidrógeno. Wind Energy in Argentina: a strategic subject towards the Hydrogen Economy.

Identificación/caracterización del problema: El abastecimiento energético en base a fuentes no tradicionales o recursos no renovables es un tema altamente estratégico en las agendas de los Estados. El petróleo se está agotando y las existencias no alcanzarán para abastecer el consumo mundial.Esto ha llevado a Gobiernos a implementar alternativas de producción energética basadas en fuentes no tradicionales, tales como el Hidrógeno (H2), lo cual creará una Economía basada en el Hidrógeno.Argentina cuenta con una matriz energética dependiente en un 90 por ciento del petróleo y con reservas certificadas de petróleo y gas natural para 8,6 y 9,4 años respectivamente. Sin duda, los desafíos próximos serán: a) crear las herramientas necesarias para minimizar una potencial crisis energética en el corto plazo, y b) desarrollar políticas energéticas que articulen su autoabastecimiento e inserción en la Economía del Hidrógeno. Dado que Argentina cuenta con uno de los recursos renovables más importantes del mundo, "el viento", tiene condiciones inmejorables para obtener Hidrógeno (H2) por electrólisis del agua, utilizando energía eléctrica proveniente de fuentes renovables como la eólica (EE). Es por ello que apostar al desarrollo local del H2 basado en la EE nos ofrecerá como país, un rol estratégico en la futura Economía del Hidrógeno.Objetivo General: Identificar la actual Matriz Energética Argentina y reconocer los factores limitantes y oportunidades para la diversificación de la misma, utilizando la Energía Eólica (EE) como pilar hacia la Economía del Hidrógeno (Econo-H2). El fin último será esbozar herramientas de política energética e instrumentos regulatorios pertinentes, que sirvan de base para la formulación de una macro política energética.Metodología de Investigación: Se utilizarán técnicas de análisis de la siguiente información:a) Documental (textos, artículos, información periodística)b) Técnica, Legal y administrativa) Oral (Declaraciones oficiales-privadas y entrevistas)d) Visual (imágenes, gráficos y mapas)e) Datos (cronológicos, estadísticos y geográficos)Resultados esperados: La formulación de herramientas de política energética y de instrumentos regulatorios pertinentes, que sirvan de base para la formulación de una macro política energética que considere la Energía Eólica (EE) como un pilar fundamental para la diversificación de la matriz energética actual. Asimismo se reflexionará sobre la importancia de asociar la EE a la producción masiva del hidrógeno (H2) para la inserción y proyección futura de la Argentina hacia la Economía del Hidrógeno.Importancia del Proyecto: Argentina ha ratificado el protocolo de Kioto y forma parte de la Johannesburg Renewable Energy Coalition (JREC), por la cual ha asumido compromisos para fijar políticas nacionales de incentivo para el desarrollo de uso de energías renovables.Sin embargo, y a pesar de una serie de iniciativas y leyes promulgadas relacionadas a uso de energías renovables, hasta la fecha, no se ha logrado cumplir con metas concretas.Consideramos que uno de los factores fundamentales que ha dificultado esto, se basa en la ausencia de una política de Estado de mediano y largo plazo que incluya a las energías renovables como un objetivo concreto y un sistema de instrumentos y planes complementarios que acompañen dicha política.

Assessing the structural change of strategic mobility: determinants under hypercompetitive environments

The primary purpose of this exploratory empirical study is to examine the structural stability of a limited number of alternative explanatory factors of strategic change. On the basis of theoretical arguments and prior empirical evidence from two traditional perspectives, we propose an original empirical framework to analyse whether these potential explanatory factors have remained stable over time in a highly turbulent environment. This original question is explored in a particular setting: the population of Spanish private banks. The firms of this industry have experienced a high level of strategic mobility as a consequence of fundamental changes undergone in their environmental conditions over the last two decades (mainly changes related to the new banking and financial regulation process). Our results consistently support that the effect of most explanatory factors of strategic mobility considered did not remain stable over the whole period of analysis. From this point of view, the study sheds new light on major debates and dilemmas in the field of strategy regarding why firms change their competitive patterns over time and, hence, to what extent the "contextdependency" of alternative views of strategic change as their relative validation can vary over time for a given population. Methodologically, this research makes two major contributions to the study of potential determinants of strategic change. First, the definition and measurement of strategic change employing a new grouping method, the Model-based Cluster Method or MCLUST. Second, in order to asses the possible effect of determinants of strategic mobility we have controlled the non-observable heterogeneity using logistic regression models for panel data.

An analysis of strategic paths through the decomposition of total factor productivity: the case of Spanish savings banks

The Spanish savings banks attracted quite a considerable amount of interest within the scientific arena, especially subsequent to the disappearance of the regulatory constraints during the second decade of the 1980s. Nonetheless, a lack of research identified with respect to mainstream paths given by strategic groups, and the analysis of the total factor productivity. Therefore, on the basis of the resource-based view of the firm and cluster analysis, we make use of changes in structure and performance ratios in order to identify the strategic groups extant in the sector. We attain a threeways division, which we link with different input-output specifications defining strategic paths. Consequently, on the basis of these three dissimilar approaches we compute and decompose a Hicks-Moorsteen total factor productivity index. Obtained results put forward an interesting interpretation under a multi-strategic approach, together with the setbacks of employing cluster analysis within a complex strategic environment. Moreover, we also propose an ex-post method of analysing the outcomes of the decomposed total factor productivity index that could be merged with non-traditional techniques of forming strategic groups, such as cognitive approaches.

Learning the ropes and embracing the rules: CFSP institutions as arenas for learning and strategic socialisation

The aim of this article is to analyse those situations in which learning and socialisation take place within the context of the Common Foreign and Security Policy (CFSP), in particular, at the level of experts in the Council Working Groups. Learning can explain the institutional development of CFSP and changes in the foreign policies of the Member States. Some scope conditions for learning and channels of institutionalisation are identified. Socialisation, resulting from learning within a group, is perceived as a strategic action by reflective actors. National diplomats, once they arrive in Brussels, learn the new code of conduct of their Working Groups. They are embedded in two environments and faced with two logics: the European one in the Council and the national one in the Ministries of Foreign Affairs (MFA). The empirical evidence supports the argument that neither rational nor sociological approaches alone can account for these processes.

Strategic investment and international outsourcing in unionised oligopoly

We critically consider the conventional belief that the attractiveness of international outsourcing lies in cheaper labour costs overseas and that it offers a means to ‘escape’ the power of unions. We develop an oligopoly model in which firms facing unionised domestic labour market choose between producing an intermediate in-house or outsourcing it to a non-unionised foreign supplier that makes a relationship specific investment in developing the intermediate. We show that outsourcing typically results in higher wages and does not always reduce marginal costs. Trade liberalisation favours outsourcing particularly for the relatively less efficient firms.

Employment Protection, Flexibility and Firms’ Strategic Location Decisions under Uncertainty

We construct a model in which oligopolistic firms decide between locating in a country where employment protection implies costly output adjustments and in one without employment protection. Using a two-period three-stage game with uncertainty, we demonstrate that location is influenced by both flexibility and strategic concerns. The strategic effects under Cournot work towards domestic anchorage in the country with employment protection while those under Bertrand do not. Strategic agglomeration can occur in the inflexible country under Cournot and even under Bertrand, provided uncertainty and foreign direct investment costs are low.
