A Avaliação Imobiliária e a sua relação com o Investimento

O presente relatório visa cumprir os requisitos da unidade curricular Dissertação, Projeto ou Estágio (DIPRE) do mestrado em Engenharia Civil do Instituto Superior de Engenharia do Porto (ISEP). O estágio curricular decorreu na empresa VPM - Vaz Pinto Mendes - Unipessoal Lda, sob o tema: “A avaliação imobiliária e a sua relação com o investimento”. A avaliação imobiliária visa determinar o valor associado aos bens imóveis. Pode ser aplicada a todo o tipo de bens imóveis, tais como: apartamentos e moradias uni e multifamiliares, espaços comerciais e de serviços, quintas, unidades hoteleiras e industriais, complexos desportivos, entre outros. A avaliação imobiliária poderá ser solicitada por parte de proprietários ou arrendatários dos imóveis, por empresas, tribunais, advogados e solicitadores. Apresenta diversos fins, tais como a determinação do valor de indemnização devido a expropriações, o financiamento hipotecário para compra ou construção de imóveis, partilhas, estudo de um investimento financeiro, intenção de venda ou arrendamento, efeitos fiscais ou apenas o simples conhecimento do valor aproximado das propriedades que se possui. O presente estudo visa abordar o atual mercado imobiliário nacional, o procedimento de realização de uma avaliação imobiliária e principalmente os métodos de avaliação tradicionais.

Clustering aplicado à Bolsa de Valores de Lisboa

O objetivo desta dissertação foi estudar um conjunto de empresas cotadas na bolsa de valores de Lisboa, para identificar aquelas que têm um comportamento semelhante ao longo do tempo. Para isso utilizamos algoritmos de Clustering tais como K-Means, PAM, Modelos hierárquicos, Funny e C-Means tanto com a distância euclidiana como com a distância de Manhattan. Para selecionar o melhor número de clusters identificado por cada um dos algoritmos testados, recorremos a alguns índices de avaliação/validação de clusters como o Davies Bouldin e Calinski-Harabasz entre outros.

Financing local development through crowdfunding: An empirical analysis of social projects in Portugal

Crowdfunding (CF) is an increasingly attractive source to fund social projects. However, to our best knowledge, the study of CF for social purposes has remained largely unexplored in the literature. This research envisages a detailed examination of the role of CF on the early-stage of the social projects at regional level. By comparing the characteristics of the projects available in the Portuguese Social Stock Exchange (PSSE) platform with others that did not use this source of financial support, we explore its role on regional development. The results we got show that, in most cases, both PSSE and Non-Governmental Organizations projects complemented the services offered by the State or by the private sector. Furthermore, about a quarter of the projects present in PSSE operated in areas that were not being addressed neither by the services offered by the State nor by the ones of the private sector. The results attained show that more recent social ventures have a greater propensity to use PSSE. The same is find in those organizations which work closely with the target audience. We also observed that the use of PSSE was correlated with the geographical scope of the Social Venture. The circumstance of having the social organization acting at a local or regional level seems to be strongly associated with the possibility of using social crowdfunding for financing social projects.

Financing social ventures by crowdfunding: The inflluence of entrepreneurs’ personality traits

Purpose – This research aims to understand the role played by social entrepreneurs’ personality traits on the choice between the traditional donation model and social crowdfunding (CF) to finance social projects. Design/methodology/approach – Social CF is examined as an instrument to capture funds for social projects, and the particular case of the Portuguese Social Stock Exchange (PSSE) is presented. The approach is quantitative in nature and the data were collected through a questionnaire that was emailed to non-governmental organizations in Portugal and founders of the projects listed on PSSE. Logistic regression was employed to predict the probability that a social entrepreneur would use PSSE rather than traditional financing. The predictor variables were based on the big five personality traits. Findings – Our investigation reveals that the agreeableness and neuroticism factors were not even considered in the results of the factorial analysis, which indicates the minor importance of these personality traits in the funding decisions of the Portuguese social entrepreneurs. The same applies to the factors of openness to new experiences and extraversion, which, although considered in the logistic analysis, showed no statistical significance. Finally, the conscientiousness personality trait seems to be the only factor that might explain the use of the PSSE platform.Originality/value – Studies on the profile of the social entrepreneurs that use CF for financing social projects are relatively rare, specifically in the context of Social Stock Exchange platforms. Additionally, there is a need to carry out more empirical evidence about the effect of social entrepreneurs’ personality traits on the decision to finance social projects through social CF platforms vis-a-vis the traditional donation model.
