Multiobjective Evolutionary Algorithms for Portfolio Management: A comprehensive literature review

Abstract: In this paper we provide a review of the current state of research on Portfolio Management with the support of Multiobjective Evolutionary Algorithms (MOEAs). Second we present a methodological framework for conducting a comprehensive literature review on the Multiobjective Evolutionary Algorithms (MOEAs) for the Portfolio Management. Third, we use this framework to gain an understanding of the current state of the MOEAs for the Portfolio Management research field and fourth, based on the literature review, we identify areas of concern with regard to MOEAs for the Portfolio Management research field.

The effect of board size and composition on European bank performance

Abstract: Banks are “special” financial institutions generating distinct corporate governance challenges. The present paper examines the relationship between two of the most pertinent corporate governance factors—that is, the size of the Board of Directors and the proportion of non-executive directors—and firm performance on a sample of 58 large European banks over the period 2002–2004. The empirical analysis embraces a number of bank-specific variables. Our results reveal that bank profitability is negatively related to the size of the Board of Directors, while the impact of Board composition, although positive in all models, is, in most cases, insignificant. The results are robust after controlling for firm-specific variables.

Improving the discriminating power of DEA: focus on globally efficient units

Abstract: We introduce in this paper the global efficiency approach as a means to improve the discriminating power of Data Envelopment Analysis (DEA). To discriminate further among the DEA efficient units, we deal only with the units that can maintain their efficiency score under common weighting structures. Then we proceed further to ranking the whole set of DEA efficient units. We compare the global efficiency approach with the multi-criteria DEA and the cross-efficiency approaches on the basis of characteristic numerical examples drawn from the literature.
