En la presente tesis se analizan los activos del mercado internacional de arte como objetos de inversión financiera alternativa a otros activos clásicos (acciones, bienes inmuebles ), para el período 1997-2006. En primer lugar, se lleva a cabo un estudio de la evolución del mercado de arte internacional, analizando la distribución de la cifra de negocios por países y categorías artísticas. A continuación, se analizan los diferentes activos que componen el mercado del arte, definiendo las características que determinan el precio de mercado de cada obra de arte. Se dedica especial atención a la variable Artista, la cual ha sido cuantificada a través de fuentes documentales y digitales, dando lugar a dos grupos de variables, las V.Redmétricas y las V.Bibliométricas. De esta forma, se ha analizado la influencia de las variables redmétricas y bibliométricas en el volumen de facturación del mercado del arte. Posteriormente, se construye un índice del mercado internacional de arte, que permita recoger los cambios experimentados en el mercado internacional de arte en su totalidad y no en un segmento del mismo (grupo de artistas o movimiento artístico) en el pasado y en base a ellos intentar predecir la evolución del mismo, a fin de de utilizarlo conjuntamente en las decisiones de inversión con otros sectores de actividad económica, fundamentalmente los sectores bursátiles e inmobiliario. Por último, una vez analizada la mayor rentabilidad riesgo de la inversión en obras de arte frente a inversiones clásicas en acciones e inmuebles, se estudia el comportamiento del un inversor clásico, aquel que invierte en acciones e inmuebles consigue maximizar su rentabilidad invirtiendo en carteras diversificadas mixtas, que combinen tanto objetos de arte como acciones, para el mismo nivel de riesgo que si invirtiera únicamente en el mercado bursátil. Por otra parte, se quiere comprobar cómo el inversor arriesgado, aquel que invierte en arte tratará de reducir el riesgo, diversificando su inversión en acciones e inmuebles. En ambas ...

43 47 7 2 ; S ; [EN] This paper critically analyses the implications the digitalisation process has on individuals and organization `s behaviour. The digital era has positive aspects such as the access to information on real time from almost any geographical place combined with the shorten the length of time of processes. In addition, new economic trends and paradigms emerge in the digital era. However, we cannot deny the existence of negative or at least unexpected aspects of the digitalization. This work highlights some of the most alarming aspects of digitization that require the attention and implementation of measures by public authorities to prevent from the collateral damages the digitalisation can produce on citizenship well-being.

[EN] In recent decades, pathological consumption has become a growing behavioral misbehavior. Impulsive consumption is governed by two internal behavioral mechanisms that respond fundamentally to the hedonism or Pascal effect and to the emulation or Veblen effect. Today's development of technology acts as a catalyst of consumption by increasing access and availability to products, as well as the advertisement impact. This paper presents a compartmental discrete matrix mathematical model that allows short-term estimates of ordinary, impulsive, and pathological buyers in Spain in three different economic scenarios. The results show that impulsive and pathological buyers will increase in all the economic scenarios. Notable differences in the number of ordinary buyers are found for the group aged over 65 years. ; Ministerio de Ciencia, Innovacion y Universidades, Grant/Award Numbers: Spanish MTM2017-89664-P ; Merello, P.; De La Poza, E.; Jódar Sánchez, LA.

Spanish GDP indicator figures recover while the risk of poverty has not stopped increasing since 2007 given the continuous austerity policies adopted by Governments, while labour and welfare conditions have worsened. A new phenomenon is emerging: the flattening of the Spanish middle class. This study proposes a model to quantify the number of individuals according to their level of precariousness in Spain. The model allows us to predict the behaviour of society in Spain given the mimetic nature of humans by constructing a discrete finite epidemiological model that classifies and quantifies the population in Spain according to its risk of precariousness. Our results show a rise in the precariat of 3% (representing 39% of the total population at the end of the study). The relevance of this study lies in providing measures to governments that can mitigate the negative effects of this problem and stop its growth. Indeed tax measures to help firms to distribute their profits among employees and measures engaging a labour reform to establish limits to the rate of temporary jobs and working overtime should be considered.

This paper deals with the construction of a discrete population mathematical model for the short-term forecast until January 2016 of the electoral support of extreme ideology parties in Spain. Firstly, the nontrivial concept of extreme ideology is stated. Then, the electoral register is split in three subpopulations: supporters of extremist parties, abstentions/blank voters, and supporters of establishment parties. The model takes into account the following variables: economy measured throughout the Spanish unemployment rate; demography quantified in terms of birth and death rates and emigration; sociopolitical situation measured by the Spanish poverty indicator, trust on the Government labor indicator (GLI), and the indicator of political trust. By considering the dynamic subpopulations transits built throughout data obtained from public and private prestigious institutions and sociopolitical analysis, a system of difference equations models the electoral population behavior in Spain allowing us to compute the expected electoral support in the time horizon of January 2016. Sensitivity analysis versus uncertain parameters is performed in order to improve the reliability of the model results. ; The authors of this paper would like to thank Phd.

"This book analyzes human behaviour from an individual and collective perspective. Based on cutting-edge research, each chapter is focused on modelling economic and social behaviour at different fields and environments. The decision making process of individuals and also organizations is modelled applying innovative quantitative and qualitative approaches, explaining by their forecasted results the consequences to the specific environment of organizations. Stakeholders such as competition, customers, providers, communities, public authorities are affected by individual and organizational behavior. The book comprises the most relevant topics of current times. Researches challenged the reader by the approaches followed when presenting their works by in sighting the pillars of western societies: family, education, healthcare, culture, citizenship security, demographics, competitiveness in the framework of Europe, good and service markets, financial markets. This book offers an overview of trendy issues arising worldwide, offering a real and applicable answers to socio-economic dilemmas."

[EN] Brands are the most precious intangible companies' assets. Company managers need to know their brand value and the aspects determining it. As no transparent brands market exists, the main objective of this study was to model brand values that the world's main valuation consultants publish. The obtained results indicate that 80% of the value of these brands is accounted for by both the net results of the companies that own brands and their value on the Stock Exchange. These results allow brand values to be estimated using quantitative and objective information by simple methods, unlike those used by valuation consultants. Moreover, one temporal analysis and another for different industries confer these outcomes consistency. ; Alcaide González, MÁ.; Guadalajara Olmeda, MN.; De La Poza, E. (2021).

[EN] The companies are aware of the impact that disseminating their corporate social responsibility (CSR) performance has on how shareholders or investors perceive them. This work analyses if disseminating CSR results affects their economic¿ financial results, their scores in open¿access sustainability ranking, their brand values, and also the credit ratings that agencies S&P and Moody's confer them. For this pur- pose, the only 13 companies of the IT sector occupying a top 100 brand rankings position were selected. The results reveal that large companies come over as being more transparent in terms of sustainability, but this transparency is not related to their financial behaviour. Brand rankings collect socio¿economic and environmental information, but only the transparency in social and environmental aspects explains the public¿access CRS rankings. Finally, the results also show that this transparency affects credit ratings. ; Alcaide González, MÁ.; De La Poza, E.; Guadalajara Olmeda, MN. (2020).

[EN] Nowadays, companies have more freedom on how they can report their corporate social responsibility (CSR) actions and outcomes, despite them being increasingly important for how investors and shareholders can obtain knowledge about companies¿ non-financial aspects. This is why more importance is being attached to sustainability rankings as an additional tool to seek excellence and distinguish between companies. The main objective of the present research was to analyze the degree of similarity in sustainability valuations among the most important open-access sustainability rankings that have appeared in the last decade (Green Ranking, RepTrack, Global 100 most sustainable corporations, and Finance Yahoo Sustainability). The secondary objective was to study whether these rankings incorporated the most de facto prestigious brands, and the third objective was to learn of the influence of the level of controversy in Finance Yahoo Sustainability scores in technological companies. Our results reveal wide variability among open-access CSR rankings. Not all the most valued brands appear in the sustainability rankings, which indicates the differences between the rankings of brands and CSR rankings. Finally, the level of controversy was found to be an important aspect in companies¿ CSR scores. ; Alcaide González, MÁ.; De La Poza, E.; Guadalajara Olmeda, MN. (2019).
