The research of this thesis dissertation covers developments and applications of short-and long-term climate predictions. The short-term prediction emphasizes monthly and seasonal climate, i.e. forecasting from up to the next month over a season to up to a year or so. The long-term predictions pertain to the analysis of inter-annual- and decadal climate variations over the whole 21st century. These two climate prediction methods are validated and applied in the study area, namely, Khlong Yai (KY) water basin located in the eastern seaboard of Thailand which is a major industrial zone of the country and which has been suffering from severe drought and water shortage in recent years. Since water resources are essential for the further industrial development in this region, a thorough analysis of the potential climate change with its subsequent impact on the water supply in the area is at the heart of this thesis research. The short-term forecast of the next-season climate, such as temperatures and rainfall, offers a potential general guideline for water management and reservoir operation. To that avail, statistical models based on autoregressive techniques, i.e., AR-, ARIMA- and ARIMAex-, which includes additional external regressors, and multiple linear regression- (MLR) models, are developed and applied in the study region. Teleconnections between ocean states and the local climate are investigated and used as extra external predictors in the ARIMAex- and the MLR-model and shown to enhance the accuracy of the short-term predictions significantly. However, as the ocean state – local climate teleconnective relationships provide only a one- to four-month ahead lead time, the ocean state indices can support only a one-season-ahead forecast. Hence, GCM- climate predictors are also suggested as an additional predictor-set for a more reliable and somewhat longer short-term forecast. For the preparation of “pre-warning” information for up-coming possible future climate change with potential adverse hydrological impacts in the study region, the long-term climate prediction methodology is applied. The latter is based on the downscaling of climate predictions from several single- and multi-domain GCMs, using the two well-known downscaling methods SDSM and LARS-WG and a newly developed MLR-downscaling technique that allows the incorporation of a multitude of monthly or daily climate predictors from one- or several (multi-domain) parent GCMs. The numerous downscaling experiments indicate that the MLR- method is more accurate than SDSM and LARS-WG in predicting the recent past 20th-century (1971-2000) long-term monthly climate in the region. The MLR-model is, consequently, then employed to downscale 21st-century GCM- climate predictions under SRES-scenarios A1B, A2 and B1. However, since the hydrological watershed model requires daily-scale climate input data, a new stochastic daily climate generator is developed to rescale monthly observed or predicted climate series to daily series, while adhering to the statistical and geospatial distributional attributes of observed (past) daily climate series in the calibration phase. Employing this daily climate generator, 30 realizations of future daily climate series from downscaled monthly GCM-climate predictor sets are produced and used as input in the SWAT- distributed watershed model, to simulate future streamflow and other hydrological water budget components in the study region in a multi-realization manner. In addition to a general examination of the future changes of the hydrological regime in the KY-basin, potential future changes of the water budgets of three main reservoirs in the basin are analysed, as these are a major source of water supply in the study region. The results of the long-term 21st-century downscaled climate predictions provide evidence that, compared with the past 20th-reference period, the future climate in the study area will be more extreme, particularly, for SRES A1B. Thus, the temperatures will be higher and exhibit larger fluctuations. Although the future intensity of the rainfall is nearly constant, its spatial distribution across the region is partially changing. There is further evidence that the sequential rainfall occurrence will be decreased, so that short periods of high intensities will be followed by longer dry spells. This change in the sequential rainfall pattern will also lead to seasonal reductions of the streamflow and seasonal changes (decreases) of the water storage in the reservoirs. In any case, these predicted future climate changes with their hydrological impacts should encourage water planner and policy makers to develop adaptation strategies to properly handle the future water supply in this area, following the guidelines suggested in this study.

Information and communication technology (ICT) projects have a great potential to revolutionise the information delivery system by bridging the gap between farmers and extension personnel. aAQUA (Almost All Questions Answered) portal was launched by the Developmental Informatics Laboratory (DIL) at Indian Institute of Technology (IIT) Mumbai, Maharashtra, India in 2003 as an information providing system to deliver technology options and tailored information for the problems and queries raised by Indian dairy farmers. To measure the effectiveness of this service the attitudinal dimensions of the users of aAQUA e-Agriservice were investigated using a 22 item scale. A simple random sampling technique was used to select 120 dairy farmers from which data were collected and subjected to factor analysis to identify the underlying constructs in this research. From the attitude items, four components were extracted and named as the pessimistic, utility, technical and efficacy perspective, which influenced the development of varied level of attitudinal inclination towards the e-Agriservice. These components explained 64.40 per cent of variation in the attitude of the users towards the aAQUA e-Agriservice. This study provides a framework for technically efficient service provision that might help to reduce the pessimistic attitude of target population to adopt e-Agriservice in their farming system. The results should also be helpful for researchers, academics, ICT based service providers and policy makers to consider these perspectives while planning and implementing ICT projects.

The Japanese economy entered a long recession in spring 1997. Its economic growth has been much lower than in the US and the EU despite large fiscal stimulus packages, a monetary policy which has brought interest rates to zero since 1999, injections of public money to recapitalize banks, and programs of liberalization and deregulation. How could all these policies have failed to bring the Japanese economy back on a sustainable growth path? This paper argues that the failure of Japan's efforts to restore a sound economic environment is the result of having deliberately chosen inappropriate and inadequate monetary and fiscal instruments to tackle the macroeconomic and structural problems that have burdened the Japanese economy since the burst of the financial bubble at the beginning of the 90s. These choices were deliberate, since the "right" policies (in primis the resolution of the banking crisis) presented unbearable political costs, not only for the ruling parties, but also for the bureaucratic and business elites. The misfortunes of the Japanese economy during the long recession not only allow us to draw important economic policy lessons, but also stimulate reflections on the disruptive role on economic policies caused by powerful vested interests when an economy needs broad and deep structural changes. The final part of the paper focuses on ways to tackle Japan's banking crisis. In particular, it explores the Scandinavian solution, which, mutatis mutandis, might serve Japanese policy-makers well.

La estimación e interpretación de la estructura a plazo de la tasas de interés es de gran relevancia porque permite realizar pronósticos, es fundamental para la toma de decisiones de política monetaria y fiscal, es esencial en la administración de riesgos y es insumo para la valoración de diferentes activos financieros. Por estas razones, es necesario entender que puede provocar un movimiento en la estructura a plazo. En este trabajo se estiman un modelo afín exponencial de tres factores aplicado a los rendimientos de los títulos en pesos de deuda pública colombianos. Los factores estimados son la tasa corta, la media de largo plazo de la tasa corta y la volatilidad de la tasa corta. La estimación se realiza para el periodo enero 2010 a mayo de 2015 y se realiza un análisis de correlaciones entre los tres factores. Posterior a esto, con los factores estimados se realiza una regresión para identificar la importancia que tiene cada uno de estos en el comportamiento de las tasas de los títulos de deuda pública colombiana para diferentes plazos al vencimiento. Finalmente, se estima la estructura a plazo de las tasas de interés para Colombia y se identifica la relación de los factores estimados con los encontrados por Litterman y Scheinkman [1991] correspondientes al nivel, pendiente y curvatura.

Traditionally, school efficiency has been measured as a function of educational production. In the last two decades, however, studies in the economics of education have indicated that more is required to improve school efficiency: researchers must explore how significant changes in school organization affect the performance of at-risk students. In this paper we introduce Henry Levin’s adoption of the X-efficiency approach to education and we describe the efficient and cost-effective characteristics of one Learning Communities Project School that significantly improved its student outcomes and enrollment numbers and reduced its absenteeism rate to zero. The organizational change that facilitated these improvements defined specific issues to address. Students’ school success became the focus of the school project, which also offered specific incentives, selected teachers, involved parents and community members in decisions, and used the most efficient technologies and methods. This case analysis reveals new two elements—family training and community involvement—that were not explicit parts of Levin’s adaptation. The case of the Antonio Machado Public School should attract the attention of both social scientists and policy makers

This dissertation studies the effects of Information and Communication Technologies (ICT) on the banking sector and the payments system. It provides insight into how technology-induced changes occur, by exploring both the nature and scope of main technology innovations and evidencing their economic implications for banks and payment systems. Some parts in the dissertation are descriptive. They summarise the main technological developments in the field of finance and link them to economic policies. These parts are complemented with sections of the study that focus on assessing the extent of technology application to banking and payment activities. Finally, it includes also some work which borrows from the economic literature on banking. The need for an interdisciplinary approach arises from the complexity of the topic and the rapid path of change to which it is subject. The first chapter provides an overview of the influence of developments in ICT on the evolution of financial services and international capital flows. We include main indicators and discuss innovation in the financial sector, exchange rates and international capital flows. The chapter concludes with impact analysis and policy options regarding the international financial architecture, some monetary policy issues and the role of international institutions. The second chapter is a technology assessment study that focuses on the relationship between technology and money. The application of technology to payments systems is transforming the way we use money and, in some instances, is blurring the definition of what constitutes money. This chapter surveys the developments in electronic forms of payment and their relationship to the banking system. It also analyses the challenges posed by electronic money for regulators and policy makers, and in particular the opportunities created by two simultaneous processes: the Economic and Monetary Union and the increasing use of electronic payment instruments. The third chapter deals with the implications of developments in ICT on relationship banking. The financial intermediation literature explains relationship banking as a type of financial intermediation characterised by proprietary information and multiple interactions with customers. This form of banking is important for the financing of small and medium-sized enterprises. We discuss the effects of ICT on the banking sector as a whole and then apply these developments to the case of relationship banking. The fourth chapter is an empirical study of the effects of technology on the banking business, using a sample of data from the Spanish banking industry. The design of the study is based on some of the events described in the previous chapters, and also draws from the economic literature on banking. The study shows that developments in information management have differential effects on wholesale and retail banking activities. Finally, the last chapter is a technology assessment study on electronic payments systems in Spain and the European Union. It contains an analysis of existing payment systems and ongoing or planned initiatives in Spain. It forms part of a broader project comprising a series of country-specific analyses covering ten European countries. The main issues raised across the countries serve as the starting point to discuss implications of the development of electronic money for regulation and policies, and in particular, for monetary-policy making.

A área da “política e administração da saúde”, tem merecido um interesse crescente nas últimas décadas. Provavelmente em consequência do substancial aumento das despesas de saúde que tem ocorrido em todo o mundo mas, também porque se tem verificado uma sensível melhoria da situação de saúde das populações, o que faz com que, “policy makers”, académicos, analistas do setor e “media” tragam as questões de saúde para as primeiras páginas, valorizando-as e tentando melhorar a compreensão sobre o muito complexo processo de prestação em saúde.Não se trata no entanto de uma melhoria que usualmente seja quantificada, ocorrendo até que, se são frequentes, as tentativas de medir os custos e a produção da saúde, setor que tem uma importante dimensão económica, o mesmo não se verifica em relação aos seus resultados (o impacto que os cuidados tiveram na saúde das populações) e ainda menos em relação aos chamados “ganhos em saúde”, afinal o objectivo maior dos sistemas de saúde.Assim, entre a subida das despesas e a melhoria dos resultados, há uma falta de relacionamento que torna difícil fazer um balanço, pelo que é urgente adotar modelos de avaliação da prestação e dos seus resultados que sejam explícitos e ajudem a validar a efetividade da prestação e dos resultados obtidos. O presente trabalho pretende ser um contributo para clarificar esta questão e procurar um indicador corrente que possa ser utilizado para objetivar os “ganhos em saúde” e que, por ser quantificável, possa permitir a definição de medidas de efetividade dos resultados obtidos e de avaliação da performance dos sistemas de saúde.Não será mais uma medida de medição da produção (outputs) mas que pode resolver muitos problemas de há longos anos, e dar suporte ao confronto recursos/resultados e permitindo avaliar a performance de sistemas de saúde, com consistência face aos seus objectivos e fiabilidade, sendo capaz de detetar as mudanças e de mostrar as diferenças.

Essa pesquisa teve como preocupação central conhecer a avaliação que os estudantes do 3° ano do ensino médio da educação básica acerca da educação fornecida pela rede estadual de ensino no estado de Pernambuco quanto à preparação para o mercado de trabalho, especialmente na região do Complexo Industrial de Suape em Pernambuco, Brasil. A pesquisa contou com a participação de 130 alunos que estudavam em duas escolas do município de Ipojuca - onde se localiza o referido Complexo Industrial -, e com 07 autoridades ligadas a educação – responsáveis pelas políticas públicas nessa região e em todo estado – em Pernambuco e nas cidades do Cabo de Santo Agostinho e Ipojuca. Foram aplicados um questionário validado aos alunos e uma entrevista semi-estruturada as autoridades (secretários de estado, gerentes regionais) em educação. Na análise quantitativa fizemos uso do programa SPSS; enquanto que na análise qualitativa utilizamos a análise de discurso. A partir dos dados obtidos conseguimos como resultado que os alunos acreditam que a escola não os prepara adequadamente para o ingresso e permanência no mercado de trabalho, e acreditam ainda, que para que essa constatação possa ser modificada é preciso que haja um investimento maior na qualidade da educação como prioridade em nosso estado e em nosso país. Nesse sentido, analisamos que mesmo com todos os avanços que estão ocorrendo no Brasil, com programas e leis de incentivo a educação básica e profissional, a sociedade globalizada exige cada vez mais investimentos em educação, e que ela deixe de ser dual e torne-se integrada e onilateral, fazendo com que os alunos consigam acreditar na educação e, a partir dela se tornem sujeitos críticos e com oportunidades de ingresso no mercado com as competências que lhe são exigidas para tal fim.

The misguided belief that “this time is different” led policy-makers to permit the credit boom of the early 2000s to continue for too long, thus preparing the ground for the biggest financial crisis in living memory. But when it comes to the recovery this around, CEPS Director Daniel Gros argues in this Commentary that the belief that this time should not be different might be equally dangerous.

Private governance is currently being evoked as a viable solution to many public policy goals. However, in some circumstances it has shown to produce more harm than good, and even disastrous consequences as in the case of the financial crisis that is raging in most advanced economies. Although the current track record of private regulatory schemes is mixed, policy guidance documents around the world still require that policy-makers give priority to self- and co-regulation, with little or no additional guidance being given to policymakers to devise when, and under what circumstances, these solutions can prove viable from a public policy perspective. With an array of examples from several policy fields, this paper approaches regulation as a public-private collaborative form and attempts to identify possible policy tools to be applied by public policy-makers to efficiently and effectively approach private governance as a solution, rather than a problem. We propose a six-step theoretical framework and argue that IA techniques should: i) define an integrated framework including both the possibility that private regulation can be used as an alternative or as a complement to public legislation; ii) involve private parties in public IAs in order to define the best strategy or strategies that would ensure achievement of the regulatory objectives; and iii) contemplate the deployment of indicators related to governance and activities of the regulators and their ability to coordinate and solve disputes with other regulators.

This paper provides an overview of the ‘state of the art’ in the academic literature on EU labour migration policies. It forms part of the research agenda of Work Package 18 of the NEUJOBS project, which aims at reviewing legislation and practices regarding the labour market inclusion and protection of rights of different categories of foreign workers in European labour markets. Accordingly, particular attention is paid to the works of scholars who evaluate the status of rights of third-country national workers in relation to labour market access, employment security, social integration, etc., in European legislation on labour immigration. More specifically, the review has selected those scholarly works that focus specifically on analysing the manner in which policy-makers have addressed the granting of rights to non-EU migrant workers, and the manner in which policy agendas – through the relevant political and institutional dynamics – have found their translation in the legislation adopted. This paper consists of two core parts. In the first section, it reviews the works of scholars who have touched on these research questions with respect to the internal dimensions of EU labour migration policies. The second section does the same for the external dimensions of these policies. Both sections start off by analysing the main trends in the literature that reviews these questions for the internal and external dimensions of European migration policies as a whole, and then move on to how these ‘trends’ can (or cannot) be found translated in scholarly writings on labour migration policies more specifically. In the final section, the paper concludes by summarising the main trends and gaps in the literature reviewed, and indicates avenues for further research.

The possibility of future rapid climatic changes is a pressing concern amongst climate scientists. For example, an abrupt collapse of the ocean's Thermohaline Circulation (THC) would rapidly cool the northern hemisphere and reduce the net global primary productivity of vegetation, according to computer models. It is unclear how to incorporate such low-probability, high-impact events into the development of economics policies. This paper reviews the salient aspects of rapid climate change relevant to economists and policy makers. The main scientific certainties and uncertainties are clearly delineated, with the aim of guiding economics goals and ensuring that they retain fidelity to their scientific underpinnings.

Severe wind storms are one of the major natural hazards in the extratropics and inflict substantial economic damages and even casualties. Insured storm-related losses depend on (i) the frequency, nature and dynamics of storms, (ii) the vulnerability of the values at risk, (iii) the geographical distribution of these values, and (iv) the particular conditions of the risk transfer. It is thus of great importance to assess the impact of climate change on future storm losses. To this end, the current study employs—to our knowledge for the first time—a coupled approach, using output from high-resolution regional climate model scenarios for the European sector to drive an operational insurance loss model. An ensemble of coupled climate-damage scenarios is used to provide an estimate of the inherent uncertainties. Output of two state-of-the-art global climate models (HadAM3, ECHAM5) is used for present (1961–1990) and future climates (2071–2100, SRES A2 scenario). These serve as boundary data for two nested regional climate models with a sophisticated gust parametrizations (CLM, CHRM). For validation and calibration purposes, an additional simulation is undertaken with the CHRM driven by the ERA40 reanalysis. The operational insurance model (Swiss Re) uses a European-wide damage function, an average vulnerability curve for all risk types, and contains the actual value distribution of a complete European market portfolio. The coupling between climate and damage models is based on daily maxima of 10 m gust winds, and the strategy adopted consists of three main steps: (i) development and application of a pragmatic selection criterion to retrieve significant storm events, (ii) generation of a probabilistic event set using a Monte-Carlo approach in the hazard module of the insurance model, and (iii) calibration of the simulated annual expected losses with a historic loss data base. The climate models considered agree regarding an increase in the intensity of extreme storms in a band across central Europe (stretching from southern UK and northern France to Denmark, northern Germany into eastern Europe). This effect increases with event strength, and rare storms show the largest climate change sensitivity, but are also beset with the largest uncertainties. Wind gusts decrease over northern Scandinavia and Southern Europe. Highest intra-ensemble variability is simulated for Ireland, the UK, the Mediterranean, and parts of Eastern Europe. The resulting changes on European-wide losses over the 110-year period are positive for all layers and all model runs considered and amount to 44% (annual expected loss), 23% (10 years loss), 50% (30 years loss), and 104% (100 years loss). There is a disproportionate increase in losses for rare high-impact events. The changes result from increases in both severity and frequency of wind gusts. Considerable geographical variability of the expected losses exists, with Denmark and Germany experiencing the largest loss increases (116% and 114%, respectively). All countries considered except for Ireland (−22%) experience some loss increases. Some ramifications of these results for the socio-economic sector are discussed, and future avenues for research are highlighted. The technique introduced in this study and its application to realistic market portfolios offer exciting prospects for future research on the impact of climate change that is relevant for policy makers, scientists and economists.
