Fermentative processes for environmental remediation

The growing interest in environmental protection has led to the development of emerging biotechnologies for environmental remediation also introducing the biorefinery concept. This work mainly aimed to evaluate the applicability of innovative biotechnologies for environmental remediation and bioenergy production, throught fermentative processes. The investigated biotechnologies for waste and wastewater treatment and for the valorisation of specific feedstocks and energy recovery, were mainly focused on four research lines. 1. Biotechnology for textile wastewater treatment and water reuse that involving anaerobic and aerobic processes in combination with membrane technologies. Combinations of different treatments were also implemented for water reuse in a textile company. 2. Biotechnology for the treatment of solid waste and leachate in landfill and for biogas production. Landfill operated as Bioreactor with recirculation of the generated leachate was proposed for organic matter biostabilisation and for ammonia removal from leachate by favouring the Anammox process. 3. An innovative two-stage anaerobic process for effective codigestion of waste from the dairy industry, as cheese whey and dairy manure, was studied by combining conventional fermentative processes with a simplified system design for enhancing biomethanisation. 4) The valorisation of the glycerol waste as surplus by-product of the biodiesel industry was investigated via microbial conversion to value-added chemicals, as 1,3-propanediol. The investigated fermentative processes have been successfully implemented and reached high yields of the produced bio-chemical. The studied biotechnological systems proved to be feasible for environmental remediation and bioenergy and chemicals production.

Empirical global value chain analysis in electronics and automobile industries :An application of Asian international input-output tables

This study aims to examine the international value distribution structure among major East Asian economies and the US. The mainstream trade theory explains the gains from trade; however, global value chain (GVC) approach emphasises uneven benefits of globalization among trading partners. The present study is mainly based on this view, examining which economy gains the most and which the least from the East Asian production networks. Two key industries, i.e., electronics and automobile, are our principle focus. Input-output method is employed to trace the creation and flows of value-added within the region. A striking fact is that some ASEAN economies increasingly reduce their shares of value-added, taken by developed countries, particularly by Japan. Policy implications are discussed in the final section.

Measuring global value chains and regional economic integration : an international input-output approach

Firms that are expanding their cross-border activities, such as vertical specialization trade, outsourcing, and fragmentation productions, have brought dramatic changes to the global economy during the last two decades. In an attempt to understand the evolution of the interaction among countries or country groups, many trade-statistics-based indicators have been developed. However, most of these statistics focus on showing the direct trade-specific-relationship among countries, rather than considering the roles that intercountry and interindustrial production networks play in a global economy. This paper uses the concepts of trade in value added as measured by the input–output tables of OECD and IDE-JETRO to provide alternative indicators that show the evolution of regional economic integration and global value chains for more than 50 economies. In addition, this paper provides thoughts on how to evaluate comparative advantages on the basis of value added using an international input–output model.

China's regional economies and value chains : an interregional input-output analysis

Attempts to understand China’s role in global value chains have often noted the case of Apple's iPhone production, in particular the fact that the value added during the Chinese portion of the iPhone’s supply chain is no more than 4%. However, when we examine the Chinese economy as a whole in global production networks, China’s share in total induced value added by China’s exports of final products to the USA is about 75% in 2005. This leads us to investigate how Chinese value added is created and distributed not only internationally but also domestically. To elucidate the increasing complexity of China’s domestic production networks, this paper focuses on the measure of Domestic Value Chains (DVCs) across regions and their linkages with global markets. By using China’s 1997 and 2007 interregional input-output tables, we can understand in detail the structural changes in domestic trade in terms of value added, as well as the position and degree of participation of different regions within the DVCs.

How are global value chains fragmented and extended in China's domestic production networks?

Global value chains are supported not only directly by domestic regions that export goods and services to the world market, but also indirectly by other domestic regions that provide parts, components, and intermediate services to final exporting regions. In order to better understand the nature of a country’s position and degree of participation in global value chains, we need to more fully examine the role of individual domestic regions. Understanding the domestic components of global supply chains is especially important for large developing countries like China and India, where there may be large variations in economic scale and development between domestic regions. This paper proposes a new framework for measuring domestic linkages to global value chains. This framework measures domestic linkages by endogenously embedding a country’s domestic interregional input-output (IO) table in an international IO model. Using this framework, we can more clearly describe how global production is fragmented and extended through linkages across a country’s domestic regions. This framework will also enable us to estimate how value added is created and distributed in both domestic and international segments of global value chains. For examining the validity and usefulness of this new approach, some numerical results are presented and discussed based on the 2007 Chinese interregional IO table, China customs statistics at the provincial level, and World Input-Output Tables (WIOTs).

Tracing CO2 emissions in global value chains

This paper integrates two lines of research into a unified conceptual framework: trade in global value chains and embodied emissions. This allows both value added and emissions to be systematically traced at the country, sector, and bilateral levels through various production network routes. By combining value-added and emissions accounting in a consistent way, the potential environmental cost (amount of emissions per unit of value added) along global value chains can be estimated. Using this unified accounting method, we trace CO2 emissions in the global production and trade network among 41 economies in 35 sectors from 1995 to 2009, basing our calculations on the World Input–Output Database, and show how they help us to better understand the impact of cross-country production sharing on the environment.

Compilation of a regionally-extended inter-country input-output table and its application to global value chain analysis

Studies on the rise of global value chains (GVCs) have attracted a great deal of interest in the recent economics literature. However, due to statistical and methodological challenges, most existing research ignores domestic regional heterogeneity in assessing the impact of joining GVCs. GVCs are supported not only directly by domestic regions that export goods and services to the world market, but also indirectly by other domestic regions that provide parts, components, and intermediate services to final exporting regions. To better understand the nature of a country's position and degree of participation in GVCs, we need to fully examine the role of individual domestic regions. Understanding the domestic components of GVCs is especially important for larger economies such as China, the US, India and Japan, where there may be large variations in economic scale, geography of manufacturing, and development stages at the domestic regional level. This paper proposes a new framework for measuring domestic linkages to global value chains. This framework measures domestic linkages by endogenously embedding a target country's (e.g. China and Japan) domestic interregional input–output tables into the OECD inter-country input–output model. Using this framework, we can more clearly understand how global production is fragmented and extended internationally and domestically.

Risk sharing with Multilateral Financial Institutions in infrastructure and energy project financing : effect on capital relief for commercial banks

(Matsukawa and Habeck, 2007) analyse the main instruments for risk mitigation in infrastructure financing with Multilateral Financial Institutions (MFIs). Their review coincided with the global financial crisis of 2007-08, and is highly relevant in current times considering the sovereign debt crisis, the lack of available capital and the increases in bank regulation in Western economies. The current macroeconomic environment has seen a slowdown in the level of finance for infrastructure projects, as they pose a higher credit risk given their requirements for long term investments. The rationale for this work is to look for innovative solutions that are focused on the credit risk mitigation of infrastructure and energy projects whilst optimizing the economic capital allocation for commercial banks. This objective is achieved through risk-sharing with MFIs and looking for capital relief in project finance transactions. This research finds out the answer to the main question: "What is the impact of risk-sharing with MFIs on project finance transactions to increase their efficiency and viability?", and is developed from the perspective of a commercial bank assessing the economic capital used and analysing the relevant variables for it: Probability of Default, Loss Given Default and Recovery Rates, (Altman, 2010). An overview of project finance for the infrastructure and energy sectors in terms of the volume of transactions worldwide is outlined, along with a summary of risk-sharing financing with MFIs. A review of the current regulatory framework beneath risk-sharing in structured finance with MFIs is also analysed. From here, the impact of risk-sharing and the diversification effect in infrastructure and energy projects is assessed, from the perspective of economic capital allocation for a commercial bank. CreditMetrics (J. P. Morgan, 1997) is applied over an existing well diversified portfolio of project finance infrastructure and energy investments, working with the main risk capital measures: economic capital, RAROC, and EVA. The conclusions of this research show that economic capital allocation on a portfolio of project finance along with risk-sharing with MFIs have a huge impact on capital relief whilst increasing performance profitability for commercial banks. There is an outstanding diversification effect due to the portfolio, which is combined with risk mitigation and an improvement in recovery rates through Partial Credit Guarantees issued by MFIs. A stress test scenario analysis is applied to the current assumptions and credit risk model, considering a downgrade in the rating for the commercial bank (lender) and an increase of default in emerging countries, presenting a direct impact on economic capital, through an increase in expected loss and a decrease in performance profitability. Getting capital relief through risk-sharing makes it more viable for commercial banks to finance infrastructure and energy projects, with the beneficial effect of a direct impact of these investments on GDP growth and employment. The main contribution of this work is to promote a strategic economic capital allocation in infrastructure and energy financing through innovative risk-sharing with MFIs and economic pricing to create economic value added for banks, and to allow the financing of more infrastructure and energy projects. This work suggests several topics for further research in relation to issues analysed. (Matsukawa and Habeck, 2007) analizan los principales instrumentos de mitigación de riesgos en las Instituciones Financieras Multilaterales (IFMs) para la financiación de infraestructuras. Su presentación coincidió con el inicio de la crisis financiera en Agosto de 2007, y sus consecuencias persisten en la actualidad, destacando la deuda soberana en economías desarrolladas y los problemas capitalización de los bancos. Este entorno macroeconómico ha ralentizado la financiación de proyectos de infraestructuras. El actual trabajo de investigación tiene su motivación en la búsqueda de soluciones para la financiación de proyectos de infraestructuras y de energía, mitigando los riesgos inherentes, con el objeto de reducir el consumo de capital económico en los bancos financiadores. Este objetivo se alcanza compartiendo el riesgo de la financiación con IFMs, a través de estructuras de risk-sharing. La investigación responde la pregunta: "Cuál es el impacto de risk-sharing con IFMs, en la financiación de proyectos para aumentar su eficiencia y viabilidad?". El trabajo se desarrolla desde el enfoque de un banco comercial, estimando el consumo de capital económico en la financiación de proyectos y analizando las principales variables del riesgo de crédito, Probability of Default, Loss Given Default and Recovery Rates, (Altman, 2010). La investigación presenta las cifras globales de Project Finance en los sectores de infraestructuras y de energía, y analiza el marco regulatorio internacional en relación al consumo de capital económico en la financiación de proyectos en los que participan IFMs. A continuación, el trabajo modeliza una cartera real, bien diversificada, de Project Finance de infraestructuras y de energía, aplicando la metodología CreditMet- rics (J. P. Morgan, 1997). Su objeto es estimar el consumo de capital económico y la rentabilidad de la cartera de proyectos a través del RAROC y EVA. La modelización permite estimar el efecto diversificación y la liberación de capital económico consecuencia del risk-sharing. Los resultados muestran el enorme impacto del efecto diversificación de la cartera, así como de las garantías parciales de las IFMs que mitigan riesgos, mejoran el recovery rate de los proyectos y reducen el consumo de capital económico para el banco comercial, mientras aumentan la rentabilidad, RAROC, y crean valor económico, EVA. En escenarios económicos de inestabilidad, empeoramiento del rating de los bancos, aumentos de default en los proyectos y de correlación en las carteras, hay un impacto directo en el capital económico y en la pérdida de rentabilidad. La liberación de capital económico, como se plantea en la presente investigación, permitirá financiar más proyectos de infraestructuras y de energía, lo que repercutirá en un mayor crecimiento económico y creación de empleo. La principal contribución de este trabajo es promover la gestión activa del capital económico en la financiación de infraestructuras y de proyectos energéticos, a través de estructuras innovadoras de risk-sharing con IFMs y de creación de valor económico en los bancos comerciales, lo que mejoraría su eficiencia y capitalización. La aportación metodológica del trabajo se convierte por su originalidad en una contribución, que sugiere y facilita nuevas líneas de investigación académica en las principales variables del riesgo de crédito que afectan al capital económico en la financiación de proyectos.

La Ordenación del Territorio en las Ciudades Globales Europeas: El caso de Madrid

En la Comunidad de Madrid el modelo de ocupación del territorio en las dos últimas décadas ha obedecido a factores de oferta del mercado y no a las necesidades de la población, ello provoca un consumo de suelo y de recursos que conducen a una sobrexplotación insostenible. Las metrópolis globales están experimentando rápidas e intensas transformaciones, basadas en los paradigmas emergentes de la globalización, la gobernanza, la metropolizacion y la dispersión de las actividades en el territorio y a través de ellos se abordan los planes de Londres, París y las tentativas de Madrid. La globalización provoca la pérdida de soberanía de las administraciones publicas y la competitividad entre las ciudades globales en Europa, Londres, Paris y Madrid, son centros de poder, de concentración y crecimiento donde se produce la dualización del espacio y donde la desigualdad participa de la restructuración urbana, concentración de pobreza frente a espacios de la nueva clase emergente en donde dominan los sectores de servicios y las tecnologías de la información. Frente al desarrollo urbano neoliberal de regulación a través del mercado y basada en criterios de eficiencia de la Nueva Gestión Pública, se vislumbra la posibilidad de que la sociedad se administre a si misma por medio de acciones voluntarias y responsables que promuevan los intereses colectivos mediante el reconocimiento de su propia identidad, introduciendo el concepto de gobernanza. Frente, a la explotación del territorio por parte de la sociedad extractiva que genera corrupcion, se propone un modelo de cooperación público-privada basado en la confianza mutua, un marco regulador estable, la transparencia y la información a cuyo flujo más homogéneo contribuirán sin duda las TICs. En todo este proceso, las regiones metropolitanas en Europa se erigen como motores del crecimiento, donde los límites administrativos son superados, en un territorio cada vez más extendido y donde los gobiernos locales tienen que organizarse mediante un proceso de cooperación en la provisión de servicios que ayuden a evitar los desequilibrios territoriales. El fenómeno de la dispersión urbana en desarrollos de baja densidad, los centros comerciales periféricos, la expulsión hacia la periferia de las actividades de menor valor añadido y la concentración de funciones directivas en el centro, conducen a una fragmentación del territorio en islas dependientes del automóvil y a procesos de exclusión social por la huida de las rentas altas y la expulsión de las rentas bajas de los centros urbanos. Se crean fragmentos monofuncionales y discontinuos, apoyados en las autovías, lugares carentes de identidad y generadores de despilfarro de recursos y una falta de sostenibilidad ambiental, económica y social. El estudio de la cultura de la planificación en Europa ayuda a comprender los diferentes enfoques en la ordenación del territorio y el proceso de convergencia entre las diferentes regiones. Los documentos de la UE se basan en la necesidad de la competitividad para el crecimiento europeo y la cohesión social y en relación al territorio en los desarrollos policéntricos, la resolución del dualismo campo-ciudad, el acceso equilibrado a las infraestructuras, la gestión prudente de la naturaleza, el patrimonio y el fomento de la identidad. Se proponen dos niveles de estudio uno actual, los últimos planes de Londres y Paris y el otro la evolución de las tentativas de planes en la Región madrileña siempre en relación a los paradigmas emergentes señalados y su reflejo en los documentos. El Plan de Londres es estratégico, con una visión a largo plazo, donde se confiere un gran interés al proceso, al papel del alcalde como líder y su adaptación a las circunstancias cambiantes, sujeto a las incertidumbres de una ciudad global. El desarrollo del mismo se concibe a través de la colaboración y cooperación entre las administraciones y actores. La estructura del documento es flexible, establece orientaciones y guías indicativas, para la redacción de los planes locales, no siendo las mismas vinculantes y con escasa representación grafica. El Plan de París es más un plan físico, similar al de otros centros europeos, trabaja sobre los sectores y sobre los territorios, con información extensa, con características de “Plan Latino” por la fuerza de la expresión gráfica, pero al mismo tiempo contiene una visión estratégica. Es vinculante en sus determinaciones y normativas, se plantea fomentar, pero también prohibir. Ambos planes tratan la competitividad internacional de sus centros urbanos, la igualdad social, la inclusión de todos los grupos sociales y la vivienda como una cuestión de dignidad humana. Londres plantea la gobernanza como cooperación entre sector público-privado y la necesaria cooperación con las regiones limítrofes, en París las relaciones están más institucionalizadas resaltando la colaboración vertical entre administraciones. Ambos plantean la densificación de nodos servidos por transporte público, modos blandos y el uso los TODs y la preservación de la infraestructura verde jerarquizada, la potenciación de la red azul y la mejora del paisaje de las periferias. En las “tentativas” de planes territoriales de Madrid se constata que estuvieron sujetas a los ciclos económicos. El primer Documento las DOT del año 1984, no planteaba crecimiento, ni económico ni demográfico, a medio plazo y por ello no proponía una modificación del modelo radio concéntrico. Se trataba de un Plan rígido volcado en la recuperación del medio rural, de la ciudad, el dimensionamiento de los crecimientos en función de las dotaciones e infraestructuras existentes. Aboga por la intervención de la administración pública y la promoción del pequeño comercio. Destaca el desequilibrio social en función de la renta, la marginación de determinados grupos sociales, el desequilibrio residencia/empleo y la excesiva densidad. Incide en la necesidad de viviendas para los más desfavorecidos mediante el alquiler, la promoción suelo público y la promoción del ferrocarril para dar accesibilidad al espacio central. Aboga por el equipamiento de proximidad y de pequeño tamaño, el tratamiento paisajístico de los límites urbanos de los núcleos y el control de las actividades ilegales señalando orientaciones para el planeamiento urbano. Las Estrategias (1989) contienen una visión: la modificación del modelo territorial, mediante la intervención pública a través de proyectos. Plantea la reestructuración económica del territorio, la reconversión del aparato productivo, la deslocalización de actividades de escaso valor añadido y una mayor ubicuidad de la actividad económica. Incide en la difusión de la centralidad hacia el territorio del sur, equilibrándolo con el norte, tratando de recomponer empleo y residencia, integrando al desarrollo económico las periferias entre sí y con el centro. Las actuaciones de transporte consolidarían las actuaciones, modificando el modelo radio concéntrico facilitando la movilidad mediante la red de cercanías y la intermodalidad. El plan se basaba en el liderazgo del Consejero, no integrando sectores como el medio ambiente, ni estableciendo un documento de seguimiento de las actuaciones que evaluara los efectos de las políticas y su aportación al equilibrio territorial, a través de los proyectos realizados. El Documento Preparatorio de las Bases (1995), es más de un compendio o plan de planes, recoge análisis y propuestas de los documentos anteriores y de planes sectoriales de otros departamentos. Presenta una doble estructura: un plan físico integrador clásico, que abarca los sectores y territorios, y recoge las Estrategias previas añadiendo puntos fuertes, como el malestar urbano y la rehabilitación el centro. Plantea la consecución del equilibrio ambiental mediante el crecimiento de las ciudades existentes, la vertebración territorial basada en la movilidad y en la potenciación de nuevas centralidades, la mejora de la habitabilidad y rehabilitación integral del Centro Urbano de Madrid, y la modernización del tejido productivo existente. No existe una idea-fuerza que aglutine todo el documento, parte del reconocimiento de un modelo existente concentrado y congestivo, un centro urbano dual y dos periferias al este y sur con un declive urbano y obsolescencia productiva y al oeste y norte con una dispersión que amenaza al equilibrio medioambiental. Señala como aspectos relevantes, la creciente polarización y segregación social, la deslocalización industrial, la aparición de las actividades de servicios a las empresas instaladas en las áreas metropolitanas, y la dispersión de las actividades económicas en el territorio por la banalización del uso del automóvil. Se plantea el reto de hacer ciudad de la extensión suburbana y su conexión con el sistema metropolitano, mediante una red de ciudades integrada y complementaria, en búsqueda de un mayor equilibrio y solidaridad territorial. Las Bases del PRET (1997) tenían como propósito iniciar el proceso de concertación en que debe basarse la elaboración del Plan. Parte de la ciudad mediterránea compacta, y diversa, y de la necesidad de que las actividades económicas, los servicios y la residencia estén en proximidad, resolviéndolo mediante una potente red de transporte público que permitiese una accesibilidad integrada al territorio. El flujo de residencia hacia la periferia, con un modelo ajeno de vivienda unifamiliar y la concentración del empleo en el centro producen desequilibrio territorial. Madrid manifiesta siempre apostó por la densificación del espacio central urbanizado, produciendo su congestión, frente al desarrollo de nuevos suelos que permitieran su expansión territorial. Precisa que es necesario preservar los valores de centralidad de Madrid, como generador de riqueza, canalizando toda aquella demanda de centralidad, hacia espacios más periféricos. El problema de la vivienda no lo ve solo como social, sino como económico, debido a la pérdida de empleos que supone su paralización. Observa ya los crecimientos residenciales en el borde de la region por el menor valor del suelo. Plantea como la política de oferta ha dado lugar a un modelo de crecimiento fragmentado, desequilibrado, desestructurado, con fuertes déficits dotacionales y de equipamiento, que inciden en la segregación espacial de las rentas, agravando el proceso de falta de identidad morfológica y de desarraigo de los valores urbanos. El plan señalaba que la presión sobre el territorio creaba su densificación por las limitaciones de espacio, Incidía en limitar el peso de la intervención pública, no planteando propuestas de cooperación público-privado. La mayor incoherencia estriba en que los objetivos eran innovadores y coinciden en su mayoría con las propuestas estudiadas de Londres o Paris, pero se intentan implementar a través de un cambio hacia un modelo reticulado homogéneo, expansivo sobre el territorio, que supone un consumo de suelo y de infraestructuras para solucionar un problema inexistente, la gestión de la densidad. Durante las dos últimas décadas en ausencia de un plan regional, la postura neoliberal fue la de un exclusivo control de legalidad del planeamiento, los municipios entraron en un proceso de competencia para aprovechar las iniciales ventajas económicas de los crecimientos detectados, que proporcionaban una base económica “sólida” a unos municipios con escasos recursos en sus presupuestos municipales. La legislación se modifica a requerimiento de grupos interesados, no existiendo un marco estable. Se pierde la figura del plan no solo a nivel regional, si no en los sectores y el planeamiento municipal donde los municipios tiende a basarse en modificaciones puntuales con la subsiguiente pérdida del modelo urbanístico. La protección ambiental se estructura mediante un extenso nivel de figuras, con diversidad de competencias que impide su efectiva protección y control. Este proceso produce un despilfarro en la ocupación del suelo, apoyada en las infraestructuras viarias, y un crecimiento disperso y de baja densidad, cada vez más periférico, produciéndose una segmentación social por dualización del espacio en función de niveles de renta. Al amparo del boom inmobiliario, se produce una falta de política social de vivienda pública, más basada en la dinamización del mercado con producción de viviendas para rentas medias que en políticas de alquiler para determinados grupos concentrándose estas en los barrios desfavorecidos y en la periferia sur. Se produce un incremento de la vivienda unifamiliar, muchas veces amparada en políticas públicas, la misma se localiza en el oeste principalmente, en espacios de valor como el entorno del Guadarrama o con viviendas más baratas por la popularización de la tipología en la frontera de la Región. El territorio se especializa a modo de islas monofuncionales, las actividades financieras y de servicios avanzados a las empresas se localizan en el norte y oeste próximo, se pierde actividad industrial que se dispersa más al sur, muchas veces fuera de la región. Se incrementan los grandes centros comerciales colgados de las autovías y sin población en su entorno. Todo este proceso ha provocado una pérdida de utilización del transporte público y un aumento significativo del uso del vehículo privado. En la dos últimas décadas se ha producido en la región de Madrid desequilibrio territorial y segmentación social, falta de implicación de la sociedad en el territorio, dispersión del crecimiento y un incremento de los costes ambientales, sociales y económicos, situación, que solo, a través del uso racional del territorio se puede reconducir, apoyado en una planificación integrada sensible y participativa. ABSTRACT In Madrid the model of land occupation in the past two decades has been driven by market supply factors rather than the needs of the population. This results in a consumption of land and resources that leads to unsustainable overexploitation. Addressing this issue must be done through sensitive and participatory integrated planning. Global cities are experiencing rapid and intense change based on the emerging paradigms of globalization, governance, metropolization and the dispersion of activities in the territory. Through this context, a closer look will be taken at the London and Paris plans as well as the tentative plans of Madrid. Globalization causes the loss of state sovereignty and the competitiveness among global cities in Europe; London, Paris and Madrid. These are centres of power, concentration and growth where the duality of space is produced, and where inequality plays a part in urban restructuration. There are concentrated areas of poverty versus areas with a new emerging class where the services sector and information technologies are dominant. The introduction of ICTs contributes to a more homogeneous flow of information leading, us to the concept of governance. Against neoliberal urban development based on free market regulations and efficiency criteria as established by the “New Public Management”, emerge new ways where society administers itself through voluntary and responsible actions to promote collective interests by recognizing their own identity. A new model of public-private partnerships surfaces that is based on mutual trust, transparency, information and a stable regulatory framework in light of territorial exploitation by the “extractive society” that generates corruption. Throughout this process, European metropolitan regions become motors of growth where administrative boundaries are overcome in an ever expanding territory where government is organized through cooperative processes to provide services that protect against regional imbalances. Urban sprawl or low-density development as seen in peripheral shopping centres, the off-shoring of low added-value activities to the periphery, and the concentration of business and top management functions in the centre, leads to a fragmentation of the territory in automobile dependent islands and a process of social exclusion brought on by the disappearance of high incomes. Another effect is the elimination of low income populations from urban centres. In consequence, discontinuous expansions and mono-functional places that lack identity materialize supported by a highway network and high resource consumption. Studying the culture of urban planning in Europe provides better insight into different approaches to spatial planning and the process of convergence between different regions. EU documents are based on the need of competitiveness for European growth and social cohesion. In relation to polycentric development territory they are based on a necessity to solve the dualism between field and city, balanced access to infrastructures, prudent management of nature and solidifying heritage and identity Two levels of study unfold, the first being the current plans of London and Île-de-France and the second being the evolution of tentative plans for the Madrid region as related to emerging paradigms and how this is reflected in documents. The London Plan is strategic with a long-term vision that focuses on operation, the role of the mayor as a pivotal leader, and the adaptability to changing circumstances brought on by the uncertainties of a global city. Its development is conceived through collaboration and cooperation between governments and stakeholders. The document structure is flexible, providing guidance and indicative guidelines on how to draft local plans so they are not binding, and it contains scarce graphic representation. The Plan of Paris takes on a more physical form and is similar to plans of other European centres. It emphasizes sectors and territories, using extensive information, and is more characteristic of a “Latin Plan” as seen in its detailed graphic expression. However, it also contains a strategic vision. Binding in its determinations and policy, it proposes advancement but also prohibition. Both plans address the international competitiveness of urban centres, social equality, inclusion of all social groups and housing as issues of human dignity. London raises governance and cooperation between public and private sector and the need for cooperation with neighbouring regions. In Paris, the relations are more institutionalized highlighting vertical collaboration between administrations. Both propose nodes of densification served by public transportation, soft modes and the use of TOD, the preservation of a hierarchical green infrastructure, and enhancing the landscape in urban peripheries. The tentative territorial plans for the Madrid region provide evidence that they were subject to economic cycles. The first document of master guidelines (1984) does not address either economic or demographic growth in the mid term and therefore does not propose the modification of the radio-concentric model. It is a rigid plan focused on rural and urban recovery and the dimensioning of growth that depends on endowments and infrastructures. It advocates government intervention and promotes small business. The plan emphasizes social imbalance in terms of income, marginalization of certain social groups, the imbalance of residence/employment and excessive density. It stresses the need for social rent housing for the underprivileged, promotes public land, and the supports rail accessibility to the central area. It backs facilities of proximity and small size, enhancing the landscaping of city borders, controlling illegal activities and draws out guidelines for urban planning. The strategies (1989) contain a vision: Changing the territorial model through public intervention by means of projects. They bring to light economic restructuring of territory, the reconversion of the productive apparatus, relocation of low value-added activities, and greater ubiquity of economic activity. They also propose the diffusion of centrality towards southern territories, balancing it with the north in an attempt to reset employment and residence that integrates peripheral economic development both in the periphery and the centre. Transport would consolidate the project, changing the radius-concentric model and facilitating mobility through a commuter and inter-modality network. The plan derives itself from the leadership of the minister and does not integrate sectors such as environment. It also does not incorporate the existence of a written document that monitors performance to evaluate the effects of policies and their contribution to the territorial balance. The Preparatory Document of the Bases, (1995) is more a compendium, or plan of plans, that compiles analysis and proposals from previous documents and sectorial plans from other departments. It has a dual structure: An integrating physical plan covering the sectors and territories that includes the previous strategies while adding some strengths. One such point is the urban discomfort and the rehabilitation of the centre. It also poses the achievement of environmental balance through the growth of existing cities, the territorial linking based on mobility, strengthening new centres, improving the liveability and comprehensive rehabilitation of downtown Madrid, and the modernization of the existing production network. There is no one powerful idea that binds this document. This is due to the recognition of an existing concentrate and congestive model, a dual urban centre, two eastern and southern suburbs suffering from urban decay, and an obsolescent productive north and west whose dispersion threatens the environmental balance. Relevant aspects the document highlights are increasing polarization and social segregation, industrial relocation, the emergence of service activities to centralized companies in metropolitan areas and the dispersion of economic activities in the territory by the trivialization of car use. It proposes making the city from the suburban sprawl and its connection to the metropolitan system through a network of integrated and complementary cities in search of a better balance and territorial solidarity. The Bases of PRET (1997) aims to start the consultation process that must underpin the development of the plan. It stems from a compact and diverse Mediterranean city along with the need for economic activities, services and residences that are close. To resolve the issue, it presents a powerful network of public transport that allows integrated accessibility to the territory. The flow of residence to the periphery based on a foreign model of detached housing and an employment concentration in the centre produces territorial imbalance. Madrid always opted for the densification of the central space, producing its congestion, against the development of new land that would allow its territorial expansion. The document states that the necessity to preserve the values of the housing problem is not only viewed as social, but also economic due to the loss of jobs resulting from their paralysis. It notes the residential growth in the regional border due to the low price of land and argues that the policy of supply has led to a fragmented model of growth that is unbalanced, unstructured, with strong infrastructure and facility deficits that affect the spatial segregation of income and aggravate the lack of morphological identity, uprooting urban values. The pressure on the territory caused its densification due to space limitation; the proposed grid model causes land consumption and infrastructure to solve a non-problem, density. Focusing on limiting the weight of public intervention, it does not raise proposals for public-private cooperation. The biggest discrepancy is that the targets were innovative and mostly align with the proposals in London and Paris. However, it proposes to be implemented through a shift towards a uniform gridded model that is expansive over territory. During the last two decades, due to the absence of a regional plan, a neoliberal stance held exclusive control of the legality of urban planning. The municipalities entered a competition process to take advantage of initial economic benefits of such growth. This provided a “solid” economic base for some municipalities with limited resources in their municipal budgets. The law was amended without a legal stable framework at the request of stakeholders. The character of the plan is lost not only regionally, but also in the sectors and municipal planning. This tends to be based on specific changes with the loss of an urban model. Environmental protection is organized through an extensive number of protection figures with diverse competencies that prevent its effective protection. This process squanders the use of the land, backed by increasing road infrastructure, dispersed occupations with low-density growth causing a social segmentation due to space duality based on income levels. During the housing boom, there is a reduction in social public housing policy mostly due to a boost in the market of housing production for average incomes than in rental policies for needy social groups that focus on disadvantaged neighbourhoods and southern suburbs. As a result, there is an increase in single-family housing, often protected by public policy. This is located primarily in the west in areas of high environmental value such as Guadarrama. There is also cheaper housing due to the popularization of typology in the border region. There, territory works as a mono-functional islands. Financial activities and advanced services for companies are located to the north and west where industrial activity is lost as it migrates south, often outside the region. The number of large shopping centres hanging off the highway infrastructure with little to no surrounding population increases. This process leads to the loss of dependency on public transport and a significant increase in the use of private vehicles. The absence of regional planning has produced more imbalance, more social segmentation, more dispersed growth and a lot of environmental, social and economic costs that can only be redirected through rational territorial.

Memo to Merkel: Post-election Germany and Europe. Bruegel Policy Brief 2013/05, 24 September 2013

Recent economic data points to the seeds of an economic recovery in the European Union. However, significant risks remain and bold policies are still needed. There are three central risks. Competitiveness adjustment is incomplete, casting doubt on the sustainability of public debt. Banking remains unstable and fragmented along national lines, resulting in unfavorable financial conditions, which further erode growth, job creation and competitiveness. Rising unemployment, especially among the young, is inequitable, unjust and politically risky. Germany has a central role to play in addressing these risks. The new German government should work on three priorities: Domestic economic policy should be more supportive of growth and adjustment, with higher public investment, a greater role for high-value added services, and more supportive immigration policy. Germany should support a meaningful banking union with a centralised resolution mechanism requiring a transfer of sovereignty to Europe for all countries including Germany. The establishment of a private investment initiative combined with a European Youth Education Fund and labour market reforms should be promoted. Building on these priorities, a significant deepening of the euro area is needed, with a genuine transfer of sovereignty, stronger institutions and democratically legitimate decision-making structures in areas of common policy.

The innovation value chain and export performance:a study of Taiwanese manufacturing industries

This thesis involves the secondary data of 1806 innovative manufacturing firms derived from the database of 2nd Taiwanese Innovation Survey. Three topics are researched. The first topic investigates the innovation value chain (IVC) in Taiwanese manufacturing firms. Previous IVC studies are all done in developed countries such as UK, Ireland, Northern Ireland and Switzerland, and it leaves the gap of those non-developed countries. The result shows the overall knowledge sourcing pattern of Taiwanese manufacturing firms presenting a complementary relationship which is consistent to the previous IVC studies. The main innovation input is still derived from internal R&D which suggests more utilisation of external knowledge may boost innovation outcome. Product innovation does enhance firm growth while process innovation reduces a firm’s productivity. The second topic uses the lens of IVC to investigate the difference of the innovation process from knowledge linkages to value added between high-tech and low- tech sectors. The findings indicate (1) there are significant differences in the IVC between high- and low-tech sectors, however these are defined; (2) how you define ‘sector’ matters i.e. the nature of the high-tech and low-tech differences varies depending on whether the technology definition is carried out at the industry or firm level; and (3) the high uncertainty of innovation cause the difficulty to predict firm performance especially for those firms with high intensity of innovation. The third topic investigates the innovation-exporting relationship and explores the determinants of export performance. Product innovation enhances export performance once a firm enters international markets while process innovation affects negatively on a firm’s likelihood of being an exporter. Furthermore, IP protection is found to affect directly export performance positively.

Az optimális ár meghatározásának módszere az értékteremtés szolgálatában (The method of determining the optimal price for the service of value creation)

A tanulmány a mikroökonómia eszközrendszerét és a hazai gépjárműpiac 2013-as adatait segítségül hívva egy új módszert mutat be az ármeghatározás területén. A kutatás központi kérdése az, hogy hol található az a pont, amikor a fogyasztó elégedett a kínált minőséggel és árral – lehetőleg megfelelő időben – és a vállalat is elégedett a megszerzett profittal. A tanulmányban tehát az ármeghatározás során központi szerepet játszik a minőség és az idő, mint értékteremtő funkció. Az elemzés egyik legfőbb következtetése, hogy a profitmaximumból levezetett optimális ár a minőség és az idő különböző paraméterei mellett meghatározható. A módszer segítségével a vállalatok közgazdasági eszközrendszer segítségével kapnak egy új szemléletet működési paramétereik és egyben versenyprioritásaik (ár, költség, minőségszint, idő) felállításához. _____ The study points to a new method for determining price with the tools of microeconomics and data of the Hungarian car market. The focus of the research is on where to find the point where the consumer is satisfied with the quality and price offered – preferably right time – and the company is satisfied with the profit achieved. In this study, therefore, in setting prices plays a central role the quality and time as a value-added feature. One of the main conclusions of the analysis is that the optimal price can be determined by various parameters of the quality and time. The method of using the economic tools help companies get a new perspective and to set up their optimal operating parameters (price, cost, quality level, time).

China in Global Value Chains: Implications for Industrial Policy and Development

Rapid technological advances and liberal trade regimes permit functional reintegration of dispersed activities into new border-spanning business networks variously referred to as global value chains (GVCs). Given that the gains of a country from GVCs depend on the activities taking place in its jurisdiction and their linkages to global markets, this study starts by providing a descriptive overview of China’s economic structure and trade profile. The first two chapters of this paper demonstrate what significant role GVCs have played in China’s economic growth, evident in enhanced productivity, diversification, and sophistication of China’s exports, and how these economic benefits have propelled China’s emergence as the world’s manufacturing hub in the past two decades. However, benefits from GVC participation – in particular technological learning, knowledge building, and industrial upgrading – are not automatic. What strategies would help Chinese industries engage with GVCs in ways that are deemed sustainable in the long run? What challenges and related opportunities China would face throughout the implementation process? The last two chapters of this paper focus on implications of GVCs for China’s industrial policy and development. Chapter Three examines how China is reorienting its manufacturing sector toward the production of higher value-added goods and expanding its service sector, both domestically and internationally; while Chapter Four provides illustrative policy recommendations on dealing with the positive and negative outcomes triggered by GVCs, within China and beyond the country’s borders. To the end, this study also hopes to shed some light on the lessons and complexities that arise from GVC participation for other developing countries.

Aplicação de um value stream map nos serviços após venda automóvel

O projeto desenvolvido tem como objetivo principal a melhoria da eficiência na prestação de serviços de reparação de chapa e pintura na Caetano Auto Colisão, através da aplicação de ferramentas associadas à filosofia Lean. Apesar das ferramentas e técnicas lean estarem bem exploradas nas empresas de produção e manufatura, o mesmo não se verifica em relação às empresas da área dos serviços. O Value Stream Mapping é uma ferramenta lean que consiste no mapeamento do fluxo de materiais e informação necessários para a realização das atividades (que acrescentam e não acrescentam valor), desempenhadas pelos colaboradores, fornecedores e distribuidores, desde a obtenção do pedido do cliente até à entrega final do serviço. Através desta ferramenta é possível identificar as atividades que não acrescentam valor para o processo e propor medidas de melhoria que resultem na eliminação ou redução das mesmas. Com base neste conceito, foi realizado o mapeamento do processo de prestação de serviços de chapa e pintura e identificados os focos de ineficiência. A partir desta análise foram sugeridas melhorias que têm como objetivo atingir o estado futuro proposto assim como tornar o processo mais eficiente. Duas destas melhorias passaram pela implementação dos 5S na sala das tintas e pela elaboração de um relatório A3 para o centro de lavagens. O projeto realizado permitiu o estudo de um problema real numa empresa de serviços, bem como a proposta de um conjunto de melhorias que a médio prazo se espera virem a contribuir para a melhoria da eficiência na prestação de serviços de chapa e pintura.
