What makes people stay in or leave shrinking cities? An empirical study from Portugal

The relative attractiveness of cities as places to live determines population movements in or out of them. Understanding the appealing features of a city is fundamental to local governments, particularly for cities facing population decline. Pull and push attributes of cities can include economic aspects, the availability of amenities and psychological constructs, initiating a discussion around which factors are more relevant in explaining migration. However, a pull–push approach has been underexplored in studies of shrinking cities. In the present study, we contribute to the discussion by identifying pull and push factors in Portuguese shrinking cities. Data were collected using a face-to-face questionnaire survey of 701 residents in four shrinking cities: Oporto, Barreiro, Peso da Régua and Moura. Factor analysis and automatic linear modelling were used to analyse the data. Our results support previous findings that the economic activity of a city is the most relevant feature for retaining residents. However, other characteristics specific to each city, especially those related to heritage and natural beauty, are also shown to influence a city’s attractiveness as a place to live. The cause of population shrinkage is also found to influence residents’ assessments of the pull and push attributes of each city. Furthermore, the results show the relevance of social ties and of place attachment to inhabitants’ intention to continue living in their city of residence.

Technological evolution

The evolution of a technology and the understanding of the moment in its life cycle is of the utmost importance to the entry strategy devised by any company. Having the entry of EDP Brazil on the micro-generation market as background, the present workproject attempts to summarize the most important topics in management literature concerning the theory of technology life-cycles and the updated literature on developments of photovoltaic technology to infer the current positioning of this technology in the theoretical models. The need for this type of work stems from the very common lack of bridging between the academic research of economic aspects relevant to the evolution of technologies and the agents of research on specific technological issues. When this occurs, namely due to the external nature of research to companies, thereby escaping the harsh economic controls of a profit seeking enterprise, the evolution many times lacks the appropriate framework to be studied on a more forward looking manner and to allow for management decisions to be based on.

A edificação e consolidação do Estado Novo no concelho de Torres Vedras : do golpe militar do 28 de Maio de 1926 às Eleições Presidenciais de 13 de Fevereiro de 1949

A presente dissertação de mestrado procura abordar a edificação e consolidação do regime do Estado Novo no concelho de Torres Vedras, alicerçando a sua estrutura de análise, numa abordagem aos aspectos políticos, sociais e económicos, mais relevantes, do arco cronológico balizado entre Maio de 1926 e Fevereiro de 1949. É nosso propósito analisar, inicialmente, as mutações locais ocorridas após o golpe militar do 28 de Maio de 1926, que inaugura a Ditadura Militar (1926-1932). A compreensão desta problemática é estruturada, numa análise ao impacto daquela intentona junto da imprensa local, à designação das novas elites políticas locais e à significativa actividade da oposição local, desenvolvida até ao final de 1932. Esta abordagem inicial, mas fulcral na concretização dos objectivos, antecederá a análise à implantação das estruturas do Estado Novo (1933-1938) no concelho de Torres Vedras. A resposta a esta questão será dada, desde logo, através de quatro cenários de análise distintos. Em primeiro lugar, procura-se acompanhar a actividade das elites políticas locais e o que representavam no âmbito político-ideológico. Num segundo momento centra-se a nossa análise, na edificação do modelo corporativo e na implantação das organizações salazaristas (Legião e Mocidade Portuguesa). Num terceiro foco de análise, procuramos sintetizar a actividade da oposição local. Por fim, introduzimos a abordagem aos principais actos eleitorais da década de 30. Após a compreensão, da evolução política e institucional, ocorrida desde Maio de 1926, o início da 2.ª Guerra Mundial (1939-1945), força-nos a inflectir a análise do panorama político e institucional, para as questões económicas, sociais e ideológicas deste período. A abordagem, ao contexto internacional de guerra, é fulcral, para se compreender, de que forma o espaço territorial em estudo sentiu os efeitos do conflito. Pretende-se por um lado, esclarecer as dificuldades vivenciadas pela população local, por outro, compreender o alinhamento ideológico assumido em favor das potências em confronto. Paralelamente dar-se-á continuidade, à análise sobre a evolução corporativa local, assim como às movimentações da oposição clandestina. O último foco de abordagem recai na organização da oposição local no período do pós-guerra (1945-1949). É nosso objectivo, indagar, os contornos associados ao alinhamento das forças democráticas após o termo do conflito. Num primeiro momento, foca-se a análise, na caracterização da composição da comissão concelhia do Movimento de Unidade Democrática, surgido em Outubro de 1945, num contexto pré-eleitoral despoletado por uma aparente abertura do regime. Numa segunda conjuntura, que coincide com as Eleições Presidenciais de 13 de Fevereiro de 1949, aborda-se a constituição da comissão concelhia de apoio ao general Norton de Matos e analisa-se, as principais movimentações locais, em redor da aludida eleição.

Economic analysis in health care regulation : three essays

ABSTRACT - It is the purpose of the present thesis to emphasize, through a series of examples, the need and value of appropriate pre-analysis of the impact of health care regulation. Specifically, the thesis presents three papers on the theme of regulation in different aspects of health care provision and financing. The first two consist of economic analyses of the impact of health care regulation and the third comprises the creation of an instrument for supporting economic analysis of health care regulation, namely in the field of evaluation of health care programs. The first paper develops a model of health plan competition and pricing in order to understand the dynamics of health plan entry and exit in the presence of switching costs and alternative health premium payment systems. We build an explicit model of death spirals, in which profitmaximizing competing health plans find it optimal to adopt a pattern of increasing relative prices culminating in health plan exit. We find the steady-state numerical solution for the price sequence and the plan’s optimal length of life through simulation and do some comparative statics. This allows us to show that using risk adjusted premiums and imposing price floors are effective at reducing death spirals and switching costs, while having employees pay a fixed share of the premium enhances death spirals and increases switching costs. Price regulation of pharmaceuticals is one of the cost control measures adopted by the Portuguese government, as in many European countries. When such regulation decreases the products’ real price over time, it may create an incentive for product turnover. Using panel data for the period of 1997 through 2003 on drug packages sold in Portuguese pharmacies, the second paper addresses the question of whether price control policies create an incentive for product withdrawal. Our work builds the product survival literature by accounting for unobservable product characteristics and heterogeneity among consumers when constructing quality, price control and competition indexes. These indexes are then used as covariates in a Cox proportional hazard model. We find that, indeed, price control measures increase the probability of exit, and that such effect is not verified in OTC market where no such price regulation measures exist. We also find quality to have a significant positive impact on product survival. In the third paper, we develop a microsimulation discrete events model (MSDEM) for costeffectiveness analysis of Human Immunodeficiency Virus treatment, simulating individual paths from antiretroviral therapy (ART) initiation to death. Four driving forces determine the course of events: CD4+ cell count, viral load resistance and adherence. A novel feature of the model with respect to the previous MSDEMs is that distributions of time to event depend on individuals’ characteristics and past history. Time to event was modeled using parametric survival analysis. Events modeled include: viral suppression, regimen switch due virological failure, regimen switch due to other reasons, resistance development, hospitalization, AIDS events, and death. Disease progression is structured according to therapy lines and the model is parameterized with cohort Portuguese observational data. An application of the model is presented comparing the cost-effectiveness ART initiation with two nucleoside analogue reverse transcriptase inhibitors (NRTI) plus one non-nucleoside reverse transcriptase inhibitor(NNRTI) to two NRTI plus boosted protease inhibitor (PI/r) in HIV- 1 infected individuals. We find 2NRTI+NNRTI to be a dominant strategy. Results predicted by the model reproduce those of the data used for parameterization and are in line with those published in the literature.

To what extent do aspects of sustainability impact established firms' resilience

An organizations´ level of sustainability has so far been primarily been analyzed within the context of economic performance. This study changes that dependent variable to “resilience”, namely a company’s ability to recover from potential lethal shocks or disruptive events. The research questions aims to investigate whether sustainability and resilience are related. This study utilizes the financial crisis from 2007/08 as disruptive event, as it encompassed market phase-out but also survival by established firms. Two Swiss luxury watchmaking companies have been chosen as industry sample and the study’s investigation is based on a comparative case study approach. The latter applies both quantitative data, in the form of the respective annual company reports, and qualitative data, in the form of semi-structured interviews with three stakeholder groups. Findings indicate that the investigated measures of sustainability are related the investigated companies’ level of resilience. These findings contribute to the building of new theory towards resilience as this study outlines specifically which measures have been proven to be of relevance for companies’ resilience. Moreover, the results are of high relevance for companies that are operating in constant evolving markets and struggling adapting to any disruptive environment as it is outlined why and how comparative companies have to be sustainable in order to become more resilient towards future shocks.
