It is based on a research oriented to three main goals: 1 - the description and explanation of the formation of economic values, beliefs, attitudes and behaviors, based on a questionnaire submitted to a national sample, stratified by regional areas; 2 - the identification of the existent linkages between these micro-sociological variables and regional and national economic performance (e.g. GDP, unemployment rates, inflation, investment, debt and wages); 3 - the exploration of the role of human and social capital as moderators between micro-sociological variables and a support for different types of economic values. In this paper we explore the third goal, offering a tentative typology of economic values’ support. 2011-01-01T00:00:00Z https://www.um.edu.mt/library/oar/handle/123456789/68567 Title: Hunting rights and conservation : the Portuguese case Authors: Pacheco Coelho, Manuel Abstract: Hunting and game-preservation are interrelated. There are two fundamental traditions in the legislation on hunting property rights: the Romanic tradition and the Germanic one, with different consequences in terms of resources use and conservation. The Economic Theory of Common Resources has been applied to provide conclusions about the management and conservation of hunting resources. In this paper, we derive a model of hunting management, adapting the Gordon/Schaefer fisheries model. The conclusions of the model are confronted with Portuguese hunting regulation. 2011-01-01T00:00:00Z https://www.um.edu.mt/library/oar/handle/123456789/68566 Title: Random walks in the representation of reserves Authors: Ferreira, Manuel Alberto M.; Andrade, Marina; Filipe, José António; Pacheco Coelho, Manuel Abstract: Models based on Random Walks are presented in this work, to represent reserves. Their main objective is to study and guarantee the sustainability of pensions funds. The use of these models with this goal is a classical approach in the study of pensions funds. 2011-01-01T00:00:00Z https://www.um.edu.mt/library/oar/handle/123456789/68565 Title: The impact of corporate rebranding on the firm’s market value Authors: Branca, Ana Sofia; Borges, Maria Rosa Abstract: Rebranding corresponds to the creation of a new name, term, symbol, design or a combination of them for an established brand with the intention of developing a differentiated position in the mind of stakeholders and competitors. Increased competition has led firms to an avenue of differentiation, and rebranding has been approached by firms in order to differentiate themselves and to promote the corporate image. Corporate rebranding, although commonly referred in the press, has received little attention from academia. This paper tends to contribute to fill this gap in the academic literature, by analysing the impact that corporate image through rebranding has on the firms’ stock market value, using event study methodologies. We focus on firms listed on the Lisbon Stock Market in the period 2000 – February 2009. We do not find evidence of a positive impact of corporate rebranding on firm value, in Portuguese firms. In fact, our results suggest that these events may have a negative impact on firm value, even though our empirical evidence is weak, in supporting this conclusion. 2011-01-01T00:00:00Z
