Index Tracking Using Data-Mining Techniques and Mixed-Binary Linear Programming

Index tracking has become one of the most common strategies in asset management. The index-tracking problem consists of constructing a portfolio that replicates the future performance of an index by including only a subset of the index constituents in the portfolio. Finding the most representative subset is challenging when the number of stocks in the index is large. We introduce a new three-stage approach that at first identifies promising subsets by employing data-mining techniques, then determines the stock weights in the subsets using mixed-binary linear programming, and finally evaluates the subsets based on cross validation. The best subset is returned as the tracking portfolio. Our approach outperforms state-of-the-art methods in terms of out-of-sample performance and running times.

A pedagogically-supported TEL solution for learning nontechnical minimally invasive surgical skills across Europe

Residents learning nontechnical skills in Europe face two problems: (1) the difficulty to fit learning time in their overloaded schedules; and (2) the lack of standard pedagogical models for all countries. Online video-based repositories such as WeBSurg or WebOP provide ubiquitous access to surgical contents. However, their pedagogical facets have not been fully exploited and they are often seen as quick-reference repositories rather than full e-learning alternatives. We present a new pedagogically-supported Technology Enhanced Learning (TEL) solution, MISTELA, designed by surgeons, pedagogical experts and engineers. MISTELA aims at building a common European pedagogical model supported by ICT technologies and elearning. The solution proposes a pedagogical model based on a framework for pedagogically-informed design of e-learning platforms. It is composed of (1) an authoring tool for editing and augmenting videos; (2) a media asset management system; and (3) a virtual learning environment. Support of the European Association for Endoscopic Surgery (EAES) and validation of the solution, will help to determine its full potential.

A Valuation of SAREB, the Spanish “Bad Bank”, Upside Using the Real Options Methodology

This paper develops a model to analyze the upside potential of profitability of the SAREB (“Asset Management Company for Assets Arising from Bank Restructuring”), the Spanish “Bad Bank”. The model is based in the Real Options methodology, that is especially adequate due to the convergence of two elements, (i) depreciated assets with a high upside potential, and (ii) a highly volatile market as it has shown to be the real estate Spanish market. Our results suggest that the SAREB has a higher than expected profitability potentialthat would be dedicated to increase the return to its shareholders, mainly private banks. Consequently we also show that after the financial crisis are emerging two types of banks in Spain, in one hand the losers who are transferring their real estate assets at a deep discount, and in the other hand the winners, capturing the upside potential of those assets as shareholders of SAREB, and consequently consolidating their strength in the Spanish Real Estate Industry. It is worth to mention that Governments should make an effort in properly redistribute the wealth generated by the real Estate industry.

New agri-environmental policies for the sustainability of mountainous olive farming. Evidences from Andalusia, Spain

La sostenibilidad de los sistemas olivareros situados en zonas de pendiente y montaña (SMOPS) en Andalucía se encuentra actualmente amenazada por las elevadas tasas de abandono que afectan a estos sistemas productivos. Así, la consumación de este proceso de abandono, no sólo pondría en peligro a las propias explotaciones, sino a todo el conjunto de bienes y servicios no productivos y al patrimonio cultural generado por este sistema productivo. En este contexto, la búsqueda de alternativas políticas enfocadas a revertir este proceso se erige como una necesidad categórica en aras de garantizar en el largo plazo la sostenibilidad de los olivares de montaña. Esta tesis pretende hacer frente a esta necesidad a través de la construcción de un marco político alternativo para los SMOPS, que permita la integración simultánea de todas las dimensiones que pueden influir en su desarrollo; esto es: el marco político actual, principalmente determinado por la Política Agraria Común (PAC) de la Unión Europea (UE); las preferencias de la sociedad hacia la oferta de bienes y servicios públicos generados por los SMOPS; y las preferencias y voluntad de innovación hacia nuevos manejos y sistemas de gestión de los agricultores y propietarios de las explotaciones. Para ello, se emplea una metodología de investigación mixta, que abarca la realización de cuatro encuestas (personales y online) llevadas a cabo a los agentes o grupos de interés involucrados directa o indirectamente en la gestión de los SMOPS –ciudadanos, agricultores y propietarios y expertos-; una profunda revisión de las herramientas de política agroambiental actuales y posibles alternativas a las mismas; y el desarrollo de nuevas estrategias metodológicas para dotar de mayor precisión y fiabilidad las estimaciones obtenidas a partir del Método del Experimento de Elección (MEE) en el campo de la valoración medioambiental. En general, los resultados muestran que una estrategia de política agroambiental basada en la combinación de los Contratos Territoriales de Zona Rural (CTZR) y el manejo ecológico supondría una mejora en la sostenibilidad de los sistemas olivareros de montaña andaluces, que, al mismo tiempo, propiciaría una mejor consideración de las necesidades y demandas de los agentes implicados en su gestión. Asimismo, los hallazgos obtenidos en esta investigación demandan un cambio de paradigma en los actuales pagos agroambientales, que han de pasar de una estrategia basada en la implementación de acciones, a otra enfocada al logro de objetivos, la cual, en el caso del olivar, se podría centrar en el aumento del secuestro de carbono en el suelo. Desde un punto de vista metodológico, los resultados han contribuido notablemente a mejorar la fiabilidad y precisión de las conclusiones estimadas a partir del MEE, mediante el diseño de un novedoso proceso iterativo para detectar posibles comportamientos inconsistentes por parte de los entrevistados con respecto a su máxima Disposición al Pago (DAP) para lograr la situación considerada como “óptima” en los olivares ecológicos de montaña andaluces. En líneas generales, el actual marco institucional favorece la puesta en práctica de la mayoría de las estrategias propuestas en esta tesis; sin embargo son necesarios mayores esfuerzos para reconducir los actuales Pagos Agroambientales y Climáticos de la PAC, hacia una estrategia de política agroambiental adaptada a las necesidades y requisitos del territorio en el que se aplica, enfocada al logro de objetivos y que sea capaz de integrar y coordinar al conjunto de agentes y grupos de interés involucrados -directa o indirectamente- en la gestión de los olivares de montaña. En este contexto, se espera que la puesta en práctica de nuevas estructuras y acuerdos de gobernanza territorial juegue un importante papel en el desarrollo de una política agroambiental realmente adaptada a las necesidades de los sistemas olivareros de montaña andaluces. ABSTRACT The long-term sustainability of Andalusian sloping and mountainous olive production systems (SMOPS) is currently threatened by the high abandonment rates that affect these production systems. The effective occurrence of this abandonment process is indeed menacing not only farms themselves, but also the wide array of public goods and services provided by SMOPS and the cultural heritage held by this production system. The search of policy alternatives aimed at tackling this process is thus a central necessity. This thesis aims to undertake this necessity by building an alternative policy framework for SMOPS that simultaneously integrates the several dimensions that are susceptible to influence it, namely: the current policy framework, mainly determined by the European Union’s (EU) Common Agricultural Policy (CAP); the social preferences toward the supply of SMOPS’ public goods and services; and farmers’ preferences and willingness to innovate toward new management practices in their farms. For this purpose, we put into practice a mixed-method strategy that combines four face-to-face and online surveys carried out with SMOPS’ stakeholders -including citizens, farmers and experts-; in-depth analysis of current and alternative agrienvironmental policy (AEP) instruments; and the development of novel methodological approaches to advance toward more reliable Discrete Choice Experiment’s (DCE) outcomes in the field of environmental valuation. Overall, results show that a policy strategy based on the combination of Territorial Management Contracts (TMC) and organic management would further enhance Andalusian SMOPS’ sustainability by simultaneously taking into account stakeholders’ demands and needs. Findings also call for paradigm shift of the current action-oriented design of Agri-Environmental-Climate Schemes (AECS), toward a result-based approach, that in the case of olive orchards should particularly be focused on enhancing soil carbon sequestration. From a methodological perspective, results have contributed to improve the accuracy and feasibility of DCE outcomes by designing a novel and iterative procedure focused in ascertaining respondents’ inconsistent behaviour with respect to their stated maximum WTP for the attainment of an ideal situation to be achieved in organic Andalusian SMOPS. Generally, the present institutional framework favours the implementation of the main policy strategies proposed in this thesis, albeit further efforts are required to better conduct current CAP’s agri-environmental instruments toward a territorially targeted result-oriented strategy capable to integrate and coordinate the whole set of stakeholders involved in the management of SMOPS. In this regard, alternative governance structures and arrangements are expected to play a major role on the process of tackling SMOPS’ agri-environmental policy challenge.

Integrated plant monitoring to improve plant operation strategy and results

The more and more demanding conditions in the power generation sector requires to apply all the available technologies to optimize processes and reduce costs. An integrated asset management strategy, combining technical analysis and operation and maintenance management can help to improve plant performance, flexibility and reliability. In order to deploy such a model it is necessary to combine plant data and specific equipment condition information, with different systems devoted to analyze performance and equipment condition, and take advantage of the results to support operation and maintenance decisions. This model that has been dealt in certain detail for electricity transmission and distribution networks, is not yet broadly extended in the power generation sector, as proposed in this study for the case of a combined power plant. Its application would turn in direct benefit for the operation and maintenance and for the interaction to the energy market

Metodología de integración de actividades de adaptación al cambio climático en proyectos de desarrollo rural

Hoy en día, ya no se puede pasar por alto la necesidad de una agricultura climáticamente más inteligente para los 500 millones de pequeños agricultores del mundo (Wheeler, 2013). Estos representan aproximadamente el 60 % de la agricultura mundial y proporcionan hasta el 80 % de los alimentos en los países en vías de desarrollo, los pequeños agricultores gestionan vastas extensiones de tierra y lamentablemente incluyen los grupos con mayor proporción de personas en estado de inseguridad alimentaria. El cambio climático está transformando el contexto para la agricultura en pequeña escala. Durante siglos, los pequeños agricultores desarrollaron la capacidad de adaptarse a los cambios ambientales y la variabilidad del clima, pero la velocidad y la intensidad del cambio climático está superando su capacidad de respuesta. Si no se cambia la manera que tenemos de lidiar con el cambio climático, tanto en acciones locales como globales, es muy probable que las personas rurales de entornos vulnerables tengan que adaptarse a un calentamiento global promedio de 4 °C por encima de los niveles preindustriales para el año 2100. Esta alza de las temperaturas aumentará aún más la incertidumbre y provocará desastres naturales como las sequías, la erosión del suelo, la pérdida de biodiversidad y la escasez agua sean mucho más frecuentes. Uno de los factores más importantes para los pequeños agricultores es que ya no pueden depender de los promedios históricos, por lo que es más difícil para ellos para planificar y gestionar la producción debido a los cambios en los patrones climáticos. Algunos de los principales cultivos de cereales (trigo, arroz, maíz, etc.) han alcanzado su umbral de tolerancia al calor y un aumento de la temperatura en torno a 1,5-2 °C podría ser muy perjudicial. Estos efectos a corto plazo podrían ser agravados por otros a medio y largo plazo, los que se refieren al impacto socioeconómico en términos de oportunidades y estabilidad política. El cambio climático está haciendo que el desarrollo de la pequeña agricultura resulte mucho más caro. A nivel de proyectos, los programas resistentes al clima tienen, normalmente, unos costos iniciales más altos, tanto de diseño como de implementación. Por ejemplo, es necesario incluir gastos adicionales en infraestructura, operación y mantenimiento; desarrollo de nuevas capacidades y el intercambio de conocimientos en torno al cambio climático. También se necesita mayor inversión para fortalecer las instituciones frente a los nuevos retos que propone el cambio climático, o generar información que pueda ser de escala reducida y con enfoques que beneficien a la comunidad, el cambio climático es global pero los efectos son locales. Es, por tanto, el momento de redefinir la relación entre agricultura y medio ambiente, ya que se hace cada vez más necesario buscar mejores y más eficientes maneras para responder al cambio climático. Es importante señalar que la respuesta al cambio climático no significa reinventar todo lo que se ha aprendido sobre el desarrollo, significa aplicar un esfuerzo renovado para hacer frente a los cambios en el trabajo de cooperación al desarrollo de una manera más sistemática y más amplia. Una respuesta coherente al cambio climático requiere que la comunidad internacional reconozca la necesidad de aumentar el apoyo financiero para la adaptación así como un mayor énfasis en proporcionar soluciones diseñadas para aumentar la resiliencia1 de los pequeños agricultores a las crisis relacionadas con el clima. Con el fin de responder a algunos de los desafíos mencionados anteriormente, esta investigación pretende contribuir a fortalecer las capacidades de los pequeños productores, aquellos que actualmente están la primera línea frente a los desafíos del cambio climático, promoviendo un desarrollo que tenga un impacto positivo en sus medios de vida. La tesis se compone de cuatro capítulos. El primero define y analiza el marco teórico de las interacciones entre el cambio climático y el impacto en los proyectos de desarrollo rural, especialmente los que tienen por objetivo mejorar la seguridad alimentaria de los pequeños productores. En ese mismo capítulo, se presenta una revisión global de la financiación climática, incluyendo la necesidad de asignar suficientes recursos para la adaptación. Con el fin de lograr una mayor eficacia e impacto en los proyectos de desarrollo, la investigación desarrolla una metodología para integrar actividades de adaptación al cambio climático, presentada en el segundo capítulo. Esta metodología fue implementada y validada durante el periodo 2012-14, trabajando directamente con diferentes equipos gubernamentales en diez proyectos del Fondo Internacional de Desarrollo Agrícola ). El tercero presenta, de manera detallada, la aplicación de la metodología a los estudios de caso de Bolivia y Nicaragua, así como un resumen de las principales conclusiones en la aplicación de los ocho países restantes. Finalmente, en el último capítulo se presentan las conclusiones y un esbozo de futuras líneas de investigación. Actualmente, el tema de la sostenibilidad ambiental y el cambio climático está ganando terreno en la agenda de desarrollo. Es por ello que se alumbra esta investigación, para que a través de los resultados obtenidos y la implementación de la metodología propuesta, sirva como herramienta estratégica para la planificación y la gestión operativa a la hora de integrar iniciativas de adaptación en los proyectos de desarrollo rural. ABSTRACT The need for climate-smart agriculture for the world’s 500 million smallholder farms cannot be overlooked: they account for 60 per cent of global agriculture, provide up to 80 per cent of food in developing countries, manage vast areas of land and make up the largest share of the developing world’s undernourished. Climate change is transforming the context for smallholder agriculture. Over centuries smallholders have developed the capacity to adapt to environmental change and climate variability, but the speed and intensity of climate change is outpacing the speed of historically autonomous actions. In the absence of a profound step-change in local and global action on climate change, it is Increasingly likely that poor rural people would need to contend with an average global warming of 4 degrees above pre-industrial levels by 2100, if not sooner. Such substantial climatic change will further increase uncertainty and exacerbate weather –related disasters, droughts, biodiversity loss, and land and water scarcity. Perhaps most significantly for smallholder farmers, they can no longer rely on historical averages, making it harder for them to plan and manage production when planting seasons and weather patterns are shifting. The major cereal crops (wheat, rice, maize, etc.) are at their heat tolerance threshold and with a 1.5-2°C temperature increase could collapse. These “first-round” effects will be compounded by second-round socio-economic impacts in terms of economic opportunities and political stability. Climate change is making the development of smallholder agriculture more expensive. At project level, climate-resilient programmes typically have higher up-front design and implementation costs – e.g. infrastructure costs and initially increased asset management, operation and maintenance, more capacity-building and knowledge sharing, strengthening institutions, greater project development costs (downscaled data generation and community-based approaches), and greater costs from enhancing cross sectorial and stakeholders collaboration. Consequently it’s time to redefine the relationship between agriculture and environment as we need to look better and more efficient ways to respond to climate change. It is important to note that responding to climate change does not mean to throwing out or reinventing everything that has been learnt about development. It means a renewed effort to tackle wider and well-known development changes in a more systematic way. A coherent response to climate change requires acknowledge of the need to increase the financial support for adaptation and a continued emphasis on provided solutions designed to increase the resilience of smallholders and poor communities to shocks, which are weather related. In order to respond to some of the challenges mentioned before, this research aims to contribute to strengthen the capacities of the smallholders and to promote a development that will positively impact in the rural livelihoods of the most vulnerable smallholders farmers; those who currently are in the first line facing the challenges of climate change. The thesis has four chapters. Chapter one describes and analyses the theoretical framework of the interactions between climate change and the impact on rural development projects, especially those aimed at improving the food security of smallholders producers. In this chapter a comprehensive review of climate financing is presented, including the need to allocate sufficient resources for adaptation. In order to achieve greater effectiveness and impact on development projects, the research develops in the second chapter a methodology to integrate adaptation activities for climate change. This methodology was implemented and validated during the 2012-14 period, working directly with various government teams in ten projects of the International Fund for Agricultural Development (IFAD). The third chapter presents in detail the application of the methodology to the case studies of Bolivia and Nicaragua, as well as a summary of the main conclusions of its implementation in the remaining eight countries. The final chapter exposes the main conclusions and future research topics. At a time when environmental sustainability and climate change issues are gaining more attention, the research and obtained results through the implementation of the model methodology proposed, can be considered a strategic tool for planning and operational management to integrate adaptation initiatives in rural development projects. The use of the proposed methodology will boost incentives to scale up climate resilience programmes and integrate adaptation to climate change into wider smallholder development programmes.

Implementing the AIFMD: Success or failure? ECMI Commentary No. 34, 28 March 2013

This commentary considers the implementation of the Alternative Investment Fund Managers Directive (AIFMD) by the European Commission. The AIFMD creates an internal market for asset management and as an endeavour to develop market-based finance is an important piece of legislation for the European economy. The author, Mirzha de Manuel Aramendía, considers the implementation of some of the provisions that raised concern among industry participants. He finds that, on balance, a practical and flexible approach to implementation has been followed that should help secure the success of the framework, which at present is still uncertain. The commentary also considers the remuneration guidelines adopted recently by the European Securities and Markets Authority (ESMA). It encourages EU and national authorities to commit to the success of the AIFMD framework, as part of a broader effort to develop capital markets and reduce the historical reliance of the European economy on bank finance.

The ‘Visible Hand’ of the ECB’s Quantitative Easing. CEPS Working Document No. 407/May 2015

Quantitative easing à la ECB has produced so far an impact on long-term nominal rates through ex ante channels: signalling channels, term duration channels, and risk premia channels. The term duration channel will also lead to a lengthening of the average maturity of government debts, with possible implications for fiscal policy. The ECB’s determination to buy government bonds in a fragmented market with a low net supply may also produce an ex post impact, during the actual asset purchases, but less on nominal rates and more on financial plumbing, as recent volatility suggests. As the effects of scarce supply in collateral markets are felt, repo rates remain well below zero. Lower supply and limited re-usability of high quality collateral, capped by regulatory requirements, is a constraint on market liquidity and compresses dealers’ balance sheets. By keeping a depressed yield curve and asset prices high, QE may also accelerate the consolidation of both traditional and capital-market based (dealer) bank business models. What is less clear is how these changing business models will interact with the sharp rise of the asset management industry in the aftermath of the crisis, which raises questions about the implications for global collateral flows and deposit-like funding channels.

Metodologia adotada pela Secretaria de Estado da Saúde do Estado de São Paulo para avaliação dos hospitais administrados por organizações sociais de saúde na região metropolitana de São Paulo

O tema central deste estudo é descrever e analisar a metodologia de avaliação adotada pela Secretaria de Estado da Saúde de São Paulo para avaliar os hospitais administrados por Organizações Sociais de Saúde (OSS), localizados na região metropolitana de São Paulo. O objetivo é descrever e analisar as dimensões selecionadas pela CGCSS – Coordenadoria de Gestão de Contratos de Serviços de Saúde e identificar os indicadores e as informaçoes geradas pelas OSS e encaminhadas rotineiramente para a CGCSS, além das ações tomadas em relação ao resultado dos indicadores e metas. Trata-se de uma pesquisa qualitativa, exploratória e descritiva, sendo analisados documentos técnicos e realizadas entrevistas semiestruturadas com técnicos da Secretaria de Estado da Saúde de São Paulo e com integrantes da Comissão de Avaliação da Execução dos Contratos de Gestão das Organizações Sociais. Conclui-se que a metodologia de avaliação de desempenho da OSS atende ao disposto na legislação estadual constante na lei nº 846/98, por meio do controle dos indicadores acordados previamente. Porém, a metodologia carece de indicadores capazes de avaliar a qualidade do serviço e o uso dos recursos financeiros. Um dos fatores relevantes em relação à pesquisa foi a falta de acesso aos dados, o que constitui a falta de publicização dos dados, por parte da SES/SP. Porém com a ajuda de alguns membros da comissão foi possível o acesso tardio, por entenderem ser informações públicas.

Population ageing and the implications for finanical markets

How will financial institutions respond to the transactions and asset management needs of both the ageing population and their carers? The ageing of the population has generated increased interest from both government and business, including banking and financial services, in the sorts of services that will be required by older people, and how their money and property will be managed. This article examines the trends and implications for banking practice of this increasing population of customers and their carers.

Minding the money: A growing responsibility for informal carers

Managing the assets of older people is a common and potentially complex task of informal care with legal, financial, cultural, political and family dimensions. Older people are increasingly recognised -as having significant assets, but the family, the state, service providers and the market have competing interests in their use. Increased policy interest in self-provision and user-charges for services underline the importance of asset management in protecting the current and future health, care and accommodation choices of older people. Although 'minding the money' has generally been included as an informal care-giving task, there is limited recognition of either its growing importance and complexity or of care-givers' involvement. The focus of both policy and practice have been primarily on substitute decision-making and abuse. This paper reports an Australian national survey and semi-structured interviews that have explored the prevalence of non-professional involvement in asset management. The findings reveal the nature and extent of involvement, the tasks that informal carers take on, the management processes that they use, and that 'minding the money' is a common informal care task and mostly undertaken in the private sphere using some risky practices. Assisting informal care-givers with asset management and protecting older people from financial risks and abuse require various strategic policy and practice responses that extend beyond substitute decision-making legislation. Policies and programmes are required: to increase the awareness of the tasks, tensions and practices surrounding asset management; to improve the financial literacy of older people, their informal care-givers and service providers; to ensure access to information, advice and support services; and to develop better accountability practices.

Momentum profits following bull and bear markets

This paper examines the profitability that the widely published momentum strategy achieves following bull and bear markets. Investors can gain stronger momentum profits by adopting the continuation strategy after poor lagged market returns. The longer the duration used to describe the bear state, the stronger the momentum returns that are realised. The results contradict the theoretical findings of the investors' overconfidence model of Daniel et al. (`Investor Psychology and Security Market Under- and Over-Reactions', Journal of Finance, 53, 1839-85, 1998) and the follow-the-trend model of Kim (`Long-term Momentum Hypothesis: Contrarian and Momentum Strategies', Working Paper, 2002), but concur with the theoretical results of the traders' hesitation model of Du (`Heterogeneity in Investor Confidence and Asset Market Under- and Overreaction', Working Paper, 2002).
