A mudança do regime cambial português: Um balanço 15 anos depois de Maastricht

A mudança de regime para a estabilidade e convertibilidade cambiais deve ser enquadrada numa mudança de regime económico e financeiro. A parte monetária foi feita por pressão europeia directa mas não se pode mudar a constituição fiscal a partir de fora. Para tal, não bastam tratados nem pactos com restrições às despesas e receitas públicas, porque a constituição fiscal assenta num processo orçamental que reflecte o sistema político. A falta de complementaridade entre políticas explica que as nossas reformas nãotenham durado o suficiente para que as empresas se sintam parte interessada. O resultado da “boleia de juros” foi uma procura excessiva de bens e serviços transaccionáveis por parte dos residentes, que se manifestou quer na despesa em bens e serviços importados ou exportáveis. Tendo em conta a baixa classificação de Portugal em termos de produtividade e também em termos de atractividade para o investor, não se vai realizar o alto potencial exportador sem alterar os preços relativos. O balanço 15 anos depois de Maastricht é pois de que, sem uma estratégia sustentada de reformas, o potencial exportador não se pode realizar. Sem realizar esse potencial, não se pode restaurar uma diferencialidade portuguesa assente nas pertenças e liberdades.

A heráldica municipal portuguesa na transição do Antigo Regime para a monarquia constitucional: reflexos revolucionários

RODRIGUES, José Damião (coord.),

O uso da heráldica no interior da casa senhorial portuguesa de Antigo Regime: propostas de sistematização e entendimento

O presente texto tem como ponto de partida o levantamento heráldico operado no âmbito do projecto “A Casa Senhorial em Lisboa e no Rio de Janeiro (séculos XVII, XVIII e XIX). Anatomia dos Interiores”, nas suas vertentes arquivística, iconográfica e patrimonial. Com base nas manifestações armoriadas arroladas, vem chamar-se a atenção para o interesse de que a Heráldica se pode revestir para o estudo das artes decorativas existente no interior das casas senhoriais. Mais do que uma análise heráldica praticada em moldes tradicionais – isto é, como instrumento passível de fornecer dados para identificação e datação de comanditários ou de campanhas de obras –, a presente abordagem ambiciona caracterizar, para o período em apreço, o recurso à decoração heráldica tanto em aplicações estruturais do espaço interior, como em objectos de todo o tipo, como elementos decorativos ou funcionais integrados no recheio das casas senhoriais lisboetas. Propõe-se, assim, analisar o conjunto de tais manifestações heráldicas enquanto documento integral que funcionou como forma de auto-representação e de comunicação, conferindo uma mensagem e um sentido concretos aos objectos e aos espaços em que se inseriu.

Tool for discovering sequential patterns in financial markets

The goal of this thesis is the study of a tool that can help analysts in finding sequential patterns. This tool will have a focus on financial markets. A study will be made on how new and relevant knowledge can be mined from real life information, potentially giving investors, market analysts, and economists new basis to make informed decisions. The Ramex Forum algorithm will be used as a basis for the tool, due to its ability to find sequential patterns in financial data. So that it further adapts to the needs of the thesis, a study of relevant improvements to the algorithm will be made. Another important aspect of this algorithm is the way that it displays the patterns found, even with good results it is difficult to find relevant patterns among all the studied samples without a proper result visualization component. As such, different combinations of parameterizations and ways to visualize data will be evaluated and their influence in the analysis of those patterns will be discussed. In order to properly evaluate the utility of this tool, case studies will be performed as a final test. Real information will be used to produce results and those will be evaluated in regards to their accuracy, interest, and relevance.

State detection in a financial portfolio: a self-organizing maps approach for financial time series

This study analyses financial data using the result characterization of a self-organized neural network model. The goal was prototyping a tool that may help an economist or a market analyst to analyse stock market series. To reach this goal, the tool shows economic dependencies and statistics measures over stock market series. The neural network SOM (self-organizing maps) model was used to ex-tract behavioural patterns of the data analysed. Based on this model, it was de-veloped an application to analyse financial data. This application uses a portfo-lio of correlated markets or inverse-correlated markets as input. After the anal-ysis with SOM, the result is represented by micro clusters that are organized by its behaviour tendency. During the study appeared the need of a better analysis for SOM algo-rithm results. This problem was solved with a cluster solution technique, which groups the micro clusters from SOM U-Matrix analyses. The study showed that the correlation and inverse-correlation markets projects multiple clusters of data. These clusters represent multiple trend states that may be useful for technical professionals.

The impact of the European sovereign debt crisis on the recovering from the financial crisis: Equity returns of the banking sector

This paper analyses, through a dynamic panel data model, the impact of the Financial and the European Debt crisis on the equity returns of the banking system. The model is also extended to specifically investigate the impact on countries who received rescue packages. The sample under analysis considers eleven countries from January 2006 to June 2013. The main conclusion is that there was in fact a structural change in banks’ excess returns due to the outbreak of the European Debt Crisis, when stock markets were still recovering from the Financial Crisis of 2008.
