A finales del año 1938, cuando las debilitadas fuerzas de la República se aprestaban a sufrir la ofensiva final y victoriosa de las tropas del general Francisco Franco, el contingente de voluntarios británicos en las Brigadas Internacionales era descrito con las siguientes palabras breves y certeras: "Un panorama de rudos mineros y estibadores galeses y escoceses mezclados con hombres cultivados. Todas las profesiones representadas. Uno era proyectista aeronáutico". El destinatario confidencial de esa descripción era el gobierno conservador británico y su autor el general Molesworth, representante suyo en la comisión internacional creada por la Sociedad de Naciones para supervisar la retirada de los combatientes extranjeros integrados en las filas republicanas. ; At the end of 1938, when the weakened forces of the Republic were preparing to undergo the final and victorious offensive of General Francisco Franco's troops, the contingent of British volunteers in the International Brigades was described with the following short and accurate words: "A panorama of rugged Welsh and Scottish miners and stevedores mixed with cultivated men. All the professions represented. One was an aeronautical designer". The confidential recipient of that description was the British Conservative government and its author General Molesworth, his representative in the international commission created by the League of Nations to supervise the withdrawal of foreign fighters integrated into the republican ranks. ; peerReviewed
I examine the impact of alternative monetary policy rules on a rational asset price bubble, through the lens of an overlapping generations model with nominal rigidities. A systematic increase in interest rates in response to a growing bubble is shown to enhance the fluctuations in the latter, through its positive effect on bubble growth. The optimal monetary policy seeks to strike a balance between stabilization of the bubble and stabilization of aggregate demand. The paper's main findings call into question the theoretical foundations of the case for "leaning against the wind" monetary policies.

I analyze an extension of the New Keynesian model that features overlapping generations of finitely lived agents and (stochastic) transitions to inactivity. In contrast with the standard model, the proposed framework allows for the existence of rational expectations equilibria with asset price bubbles. I study the conditions under which bubble- driven fluctuations may emerge and the type of monetary policy rules that may prevent them. I conclude by discussing some of the model's welfare implications.

The present paper describes recent research on two central themes of Keynes General Theory: (i) the social waste associated with recessions, and (ii) the effectiveness of fiscal policy as a stabilization tool. The paper also discusses some evidence on the extent to which fiscal policy has been used as a stabilizing tool in industrial economies over the past two decades.
How can you leverage the value of your company's data? Well over a century ago oil drove the development of innovations such as the internal combustion engine, central heating and plastics, changing our world and our economy. Oil, as a technology, fueled an economic force that inexorably changed the way people lived and worked. Today, data is fueling a very similar change: it is the driving force for new business models and disruptive technologies that impact companies in every imaginable industry. The New Oil shows how data changes the traditional business paradigm. How it impacts not just high-tech, high-profile companies, but also old-school, low-tech industries all around the world; data lives and breathes within every single company. In The New Oil, Arent van 't Spijker explains how companies such as Google, Nike and Adara are leveraging a 'Data Driven Strategy'. Many other examples highlight the applications and commercial potential for data. Van 't Spijker describes five typical business models for monetizing data that help you to develop viable business models for leveraging data in your own company. He then shows how to successfully put these business models to practice. Above all, he will inspire you to follow in the footsteps of market leaders.
Tese de doutoramento em Gestão, Universidade Lusíada de Lisboa, 2019 ; Exame público realizado em 24 de Setembro de 2021 ; Este estudo tem como propósitos fundamentais, validar em que medida as práticas e políticas de gestão de recursos humanos influenciam o desempenho profissional dos docentes em instituições de ensino superior e construir um modelo conceptual da relação existente com base nas abordagens teóricas da gestão estratégica que possam influenciar o desempenho destes nas instituições onde estão inseridos. Em termos metodológicos o trabalho tem duas componentes relevantes: i) a componente teórica suportada pela revisão de literatura e ii) a componente empírica com o desenvolvimento de um estudo exploratório. O estudo apresenta-se como um trabalho motivador à investigação sobre as práticas e políticas de gestão de recursos humanos que se revestem de capital importância para o real desenvolvimento permanente de uma instituição, mormente para as Instituições de Ensino Superior. Posto que, o Ensino Superior tem uma grave responsabilidade sistemática na elaboração das soluções científicas para o desenvolvimento eficiente de uma sociedade. A nível da intervenção organizacional, sublinha-se que a literatura conceptual tem encontrado apoio empírico para afirmar que o envolvimento e participação, dentro da estratégia gestão de recursos humanos, tem preponderância significativa no desempenho profissional dos docentes. A política de remuneração tem uma influência directa e positiva no desempenho profissional dos docentes, com grande relevância nas condições de trabalho, com preponderância na remuneração. A estratégia da gestão de recursos humanos, no âmbito do recrutamento e selecção, da formação e carreira e do planeamento e organização tem influência no desempenho profissional dos docentes em instituições de ensino superior em Angola. Do ponto de visto metodológico, salienta-se que foi feita a caracterização das práticas políticas de gestão de recursos humanos declaradas ou prescritas em quatro Instituições de Ensino Superior (duas públicas e duas privadas) em Angola, descrevendo as percepções que os docentes têm das práticas e políticas de gestão de recursos humanos em uso nas organizações em que trabalham. ; This study has as fundamental purposes, to validate to which extent human resource management practices and policies influence the professional performance of teachers in higher education institutions and to build a conceptual model of the existing relationship based on theoretical approaches to strategic management that may influence their performance in the institutions where they operate. In methodological terms, the work has two relevant components: i) the theoretical component supported by the literature review and ii) the empirical component with the development of an exploratory study. The study presents itself as a motivating work for research on human resource management practices and policies that are of fundamental importance for the real permanent development of an institution, especially for Higher Education Institutions. Since, Higher Education has a serious systematic responsibility in the elaboration of scientific solutions for the efficient development of a society. In terms of organizational intervention, it is emphasized that the conceptual literature has found empirical support to affirm that the involvement and participation, within the human resources management strategy, has a significant preponderance in the professional performance of teachers. The remuneration policy has a direct and positive influence on the professional performance of teachers, with great relevance in working conditions, with a preponderance in remuneration. The strategy of human resources management, in the scope of recruitment and selection, training and career and planning and organization has an influence on the professional performance of teachers in higher education institutions in Angola. From a methodological point of view, it is emphasized that the characterization of the political practices of human resources management declared or prescribed in two public and two private higher education institutions in Angola was described, describing the perceptions that teachers have from the practices and human resource management policies in use in the organizations in which they work.
