Summary: The overall objective of this report is to propose flexible models capable of incorporating expert knowledge and preferences imprecise for decision-making within the range of portfolios. This objective has resulted in two sub-goals: first, to obtain a generalization of the model parameters with Sharpe fuzzy, "Model Sharpe with Betas Expert", which require the construction of the Betas from statistical data and expert verifying good properties both in terms of quality of information as to their treatment and the other generation of programming models based on the minimization Multicriteria away with fuzzy parameters. The selection of optimal portfolios, it is clearly a problem and it Multicriteria goals that expresses a inversor-rentabilidad, risk, liquidity, among otros-suelen be expressed in qualitative terms, lingüsticos, inaccurate. So is a good scope of optimization techniques Multicriteria Difusa. The extension of the Model Shaarpe has been carried out considering the beta of each title as a model diffuse trapezoidal incorporating data provided by the expert and any statistical estimation. The construction of Beta diffuse depend on the relationship between the values offered by the analyst and Beta Vasicek-que we chose the statistical estimation of better behavior, and the expectations about the market situation. It has designed an algorithm for constructing the beta of an asset to the various market scenarios: bearish, bullish and stationary. We present three models of programming Targets Lexicográficas for selecting portfolios with fuzzy parameters corresponding to three modeling approaches depending on the scenarios that look and two Programming Commitment using metric L1 and L *. Finally, in order to validate the proposed models have been applied to the selection of a portfolio consisting of investment funds classified by the Spanish National Securities Market as income variables.

Summary: The primary aim of the thesis is to develop a methodology that will allow future researchers can conduct empirical analysis in the philatelic market. Therefore, mindful of this, has designed a model that enables the development of databases, through the exploitation of which could be empirically analyzed philately as an object of investment. In addition, this model is implemented in methodological research itself. On the other hand, the second objective of the research is to empirically analyze what are the factors that determine the revaluation of philately. It has conducted an empirical analysis that focuses in the first instance on philately belonging to the principality of Monaco. In this first phase, discusses three of the four possible determinants include: Shortage, Quality and Acceptance. On the other hand, through the Series Europe, because it includes stamps from almost all the countries and territories issuers Philatelic Europeans, it shows if the Guarantee Issuance is, and to what extent, a crucial factor in the revaluation philatelic.

Summary: Doctoral Tesos This is a specific study of the behavior of mutual funds in equities, funds guaranteed and fixed income funds under the Spanish market investment fund. From this particularized study identifies specific characteristics of each type, applied to the development of measures of performance appropriate for each grade level tested. The formulation of these measures for evaluating the performance arises from the contrast between active and passive strategy through the comparison between the results of the fund and to evaluate the results of a theoretical portfolio of reference and therefore passive . The measures of performance derived suit the particular idioscincrasia of each type of fund and are, therefore, contribute to better decision making investment of the members and also for fund managers.
