Protesting or justifying? A latent class model for contingent valuation with attitudinal data

This article develops a latent class model for estimating willingness-to-pay for public goods using simultaneously contingent valuation (CV) and attitudinal data capturing protest attitudes related to the lack of trust in public institutions providing those goods. A measure of the social cost associated with protest responses and the consequent loss in potential contributions for providing the public good is proposed. The presence of potential justification biases is further considered, that is, the possibility that for psychological reasons the response to the CV question affects the answers to the attitudinal questions. The results from our empirical application suggest that psychological factors should not be ignored in CV estimation for policy purposes, allowing for a correct identification of protest responses.

Mota-Engil new prospects of growth: Overcoming the financial crisis

The 2008 global financial crisis caused the collapse of business key sectors, declines in consumer wealth and a fall in economic activity resulting in a global recession. In some European countries, the 2008 crisis contributed to a sovereign-debt crisis which had a strong impact in Southern European countries. The construction sector was particularly affected, with budget cuts disturbing public investment and no financing available for private constructors. This report intends to explain how Mota-Engil, faced this situation of low growth, and which strategies were adopted by the management to overcome the difficult economic conjecture, mainly in its domestic market: Portugal. The report is organized as a case-study. The first part, the case narrative, is subdivided into 6 parts, and the second part is the teaching note. The teaching note is constituted by the four questions and their respective responses.

Referenda outcomes and the influence of polls: A social network feedback process

This paper proposes a model to explain the differences between outcomes of referenda and the voting trends suggested by polls. Two main effects are at stake. First, the evolution of the voters' attitudes is conditional on the public information made available to them. Second, the predisposition toward abstention among individuals within each voting group may be different. Our model describes how these two aspects of decision making may interact, showing how publicly available information may amplify the distinct tendency toward abstention between both groups and thus affect the outcome of the referendum.

Comparateive analysis: Public and private school management systems

The Portuguese educational system has counted, for many years, with the co-existence of both public and private schools. In fact, the country’s growth and development led, in the past, to an increasing demand for free of charge public education that could only be matched through the creation of “publicly-subsidized and privately owned and managed schools”. Still, the demographic evolution of Portugal recently generated a decrease on the demand for public educational services. This situation has raised doubts about the true contribution of this type of school for the public education system. This paper aims at answering this question by isolating the impact of different property and management schemes on the performance of students, resorting to cross-section data on 9th grade students from 2010. The results corroborate the well known result on the relevance of the family socio-economic background for students’ performance, but do also sustain the existence of a significant positive impact of private ownership and management schemes on the overall performance of students. These results suggest that there might be gains associated with the expansion of such schemes within the public education system.

CTT, the mail going public

The main purpose of this case-study is to analyse CTT’s privatisation process, a previously Government-owned firm, which went public in 2013, under the terms of the adjustment program agreed between Portugal, the European institutions (ECB and European Commission) and the IMF. The emphasis will be placed on the IPO process, but also on the company itself (its history, current situation and prospects for its new phase, as a publicly listed company). This piece of work aims to evaluate the different alternatives for the privatisation of the company along with the respective implications, as well as the outcome of the actual decision taken by the Portuguese Government. One key aspect of the case is also to understand the importance that the privatisation of the Royal Mail, which can be seen as a peer of the Portuguese company, in the unfolding of the process and in the choice of the privatisation model. The case intends to show how the British process influenced the subsequent option of the Portuguese entities to sell CTT through an IPO, instead of a trade sale. All in all, the overall objective of this case-study is to analyse CTT’s successful sale process, which created the first Portuguese company with 100% free-float. 3 On the last days of November 2013, Steven Bernstein was staring at the window of his office overlooking downtown Manhattan, not even noticing the intense rain that was pouring down. As senior manager at ABC Fund, a pension fund responsible for managing more than 800 million dollars, his thoughts were focused on a very important decision that ABC Fund would have to make in just a matter of days. The American pension fund was considering whether or not to invest in the upcoming Initial Public Offering of CTT- Correios de Portugal, the Government-owned Portuguese mail company. Is this investment opportunity in accordance with the risk profile of a pension fund? Is it a wise decision to acquire shares in a Portuguese company when the country is at the centre of the European Sovereign debt crisis, going through a very demanding economic adjustment program imposed by its bail-out creditors? Would the creation of Portugal's Postal Bank make CTT a sure bet today when its price does not fully reflect the future benefits from entering financial services? Those were some of the questions that were constantly in Mr. Bernstein’s mind over the last couple of days and he was struggling to find the answers…

The relationship between the education level of successor's and the firm performance in German publicly listed family firms- an empirical analysis

The purpose of this thesis is to investigate how far the education level of the second or third generation of publicly traded German family firms affects the post-succession firm performance. By conducting a correlational and regression design, the aim is to examine how several variables influence the performance of family firms. Performance measures, for example ROA and Tobin’s q and variables, like Education level and succession periods, examine analytically that a positive succession trend will occur. However, with the used model, only a less rigid model shows empirical evidence.

Pandemia influenza A/H1N1 2009 em Portugal : estratégias de intervenção e saúde pública

RESUMO - Introdução: A necessidade de gestão da ameaça de uma pandemia obriga à gestão da incerteza absoluta. O desconhecimento científico quanto a uma série de factores tais como, as características dos vírus causadores de infecções, a efectividade das medidas de prevenção e de tratamento, contribuiu para a dificuldade de actuação a vários níveis. Face à evolução da situação epidemiológica mundial no campo da gripe, Portugal reviu e adaptou o seu plano de contingência para a gripe tendo sido homologado, em Janeiro de 2006, um novo plano – Plano de Contingência Nacional do Sector da Saúde para a Pandemia. Objectivos: O presente estudo apresenta como principais objectivos (1) a avaliação das estratégias de intervenção e respectiva implementação das medidas de saúde pública não farmacológicas, durante a pandemia da gripe de 2009; (2) a identificação dos pontos críticos na gestão das medidas de saúde pública não farmacológicas, para preparação e resposta a futuras pandemias da gripe e, por último, (3) a definição de um modelo de acompanhamento, de monitorização e de avaliação das medidas de saúde pública não farmacológicas, que permita identificar os pontos importantes a ter em conta na implementação de boas práticas de saúde pública, nos diferentes níveis de prestação de cuidados de saúde, tendo como limitação o estado da arte dos sistemas de informação e avaliação, nacionais e internacionais, existentes. Material e Métodos: Para a avaliação das estratégias de intervenção e respectiva implementação das medidas de saúde pública não farmacológicas bem como, para a identificação dos pontos críticos na gestão das respectivas medidas foram consideradas duas perspectivas: a avaliação dos resultados através do Relatório da Pandemia da Gripe e a avaliação dos resultados através das avaliações da OMS e da Euro OMS. É apresentado um modelo de acompanhamento, de monitorização e de avaliação das medidas de saúde pública não farmacológicas, a implementar na classe médica que esteve na “linha da frente”, durante a pandemia H1N1 2009 em Portugal, nos cuidados primários, hospitalares e intensivos. Resultados: Deverá existir uma representação dos profissionais de saúde para suporte das decisões de forma a assegurar uma representação alargada não só na preparação mas também, na implementação e na aplicação do Plano de Contingência. O processo de planemanto deverá ter acesso público com possibilidade de participação activa do cidadão na sua implementação. O Plano deve ter a capacidade para se adaptar à situação epidemiológica e, no terreno os exercícios de simulações durante o processo de planeamento são importantes. As orientações técnicas devem ser dinâmicas, práticas, específicas e úteis e, dever-se investir numa cultura de confiança (“right people communicating to right people”). As alterações ao plano devem partir da coordenação, comando e controlo que, nos vários níveis de decisão, devem definir claramente quem toma as decisões. Conclusões: As estratégias para as intervenções ao nível da saúde pública, continuam, no mundo hodierno a desempenhar um papel fundamental e crucial na contenção das pandemias. O modelo apresentado neste estudo procura uma abordagem objectiva para destacar não só, os elementos essenciais de actividades bem-sucedidas, mas também as áreas em que a experiência pandémica sugere que o futuro planeamento deve dar maior ênfase.
