En esta presentación se analizan las diferentes razones que contribuyen a que las Matemáticas se encuentren, hoy en día, en un primer plano de actualidad. Destacaríamos, en primer lugar, su presencia, como lenguaje y herramienta fundamental, en todas las ciencias (incluidas las sociales) y ramas de la tecnología. Nos detendremos en temas específicos en los…
Under spatial product differentiation and product design, we identify conditions for either excessive or insufficient firm entry. We extend previous settings, based on the Salop circular model, to analyze the combined role of positive demand elasticity and endogenous targeted product design. First, we show that, given the number of firms, the equilibrium level of targeted…
Abstract: In this paper we study the dynamics of economic growth and tourism evolution for 97 countries during the period 1995-2016. The variables representing economic and tourism growth are growth rates of per capita GDP and international tourism arrivals. Using the concept of economic regime, we introduce a notion of distance between the dynamical paths…
Se presentarán resultados preliminares del proyecto de investigación (en curso) que lleva el mismo nombre de la ponencia. En Uruguay, poco se sabe sobre la satisfacción laboral en el empleo turístico y ciertas variables interrelacionadas como el compromiso con el trabajo o la intención de abandonar el trabajo. Este estudio plantea como elemento novedoso en…
The relocation of production and exports from the North to the South has been a central feature of economic globalization. Using data on approximately 5,000 products, this paper describes this process over the 1996-2014 period and assesses its impact on cross-country growth. Although increased competition from lower income countries tended to have a significant negative…
Abstract: Convenient scheduling, characterized by adequate flight frequency, is the main quality attribute for airline services. However, the effect of airline alliances on this important dimension of service quality has received almost no attention in the literature. This paper fills this gap by providing such an analysis in a model where flight frequency affects schedule…
Abstract: Este trabajo analiza la evolución y los determinantes de la desigualdad salarial mensual y horaria en España desde 1995 a 2014 utilizando los datos de la Encuesta Cuatrienal de Estructura Salarial. El aumento de la jornada a tiempo parcial es la variable clave que explica el distinto comportamiento observado en ambas. La primera aumenta…
Abstract: Digitization has vastly increased the amount of new music produced and, because of streaming, has raised the number of songs available directly to consumers. While enhanced availability has levelled the playing field between already-prominent and new artists, creators may now be highly dependent on platform decisions about which songs and artist to promote. With…
Abstract: In this paper we investigate the use of consumer surplus in monopoly when the consumption of the outside good cannot be smaller than a certain number and when the weights given in the social welfare function to consumers and the firm are different. We assume quasi-linear utility and constant returns to scale. We find…
Abstract A general finding in group contest is that there is an over-expenditure of effort, that is contests between groups generate very high individual efforts (and little free riding) compared to theoretical predictions. However, in the literature the way that the prize is shared ranges only between proportional sharing to egalitarian sharing. In many environments…
