La investigación científica y la divulgación, esto es poner al alcance de un público más amplio son dos caras de una misma moneda, pero no es lo mismo. Entre los científicos y también entre los economistas encontramos a grandes investigadores que con el paso de los años también se han convertido en divulgadores muy populares…
Multivariate observations referring to parts of a whole, so-called compositions or compositional data in statistics, are common across varied scientific fields. This is for example the case when dealing with chemical concentrations, food nutritional contents, election vote shares, investment portfolios, time-use and behavioural patterns, relative abundances, amongst others. Their distinctive feature is that there is…
Currently, information systems such as sensors produce a large amount of data, which is expected to experience exponential growth in the coming years. These data are often treated as time series, which are chronologically collected data representing a time-varying function. Time series appear in a wide range of scientific fields, such as hydrology, paleoclimatology or…
Análisis de la protección de la innovación en el campo de la Inteligencia Artificial desde una perspectiva práctica. Tendencias en la protección de la IA. Obstáculos y ventajas competitivas que nos ofrece el sistema de patentes en este campo y casos de éxito que nos ayudan a inspirarnos.
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…
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…
Abstract: This paper investigates the dynamics, propagation and drivers of macroeconomic volatility from a global perspective. A hierarchical volatility factor model is designed to estimate and decompose the time-varying volatility of output growth across countries into global, regional, and idiosyncratic components. We find that the global volatility component has been systematically declining over time, which is…
Abstract El desarrollo del sector turístico ha evidenciado su relevancia a nivel agregado en términos de valor añadido y empleo generado. Sin embargo, la mayoría de los proyectos y políticas turísticas parten de una iniciativa local. La evaluación de su éxito requiere de un análisis local o regional que requiere del entendimiento del comportamiento de…
ABSTRACT: Adaptive learning (AL) takes over other features needed to generate a sizable term premium under rational expectations. Indeed, a time-varying term premium emerges in a first-order approximation of a DSGE model under AL. We estimate a real-time AL model that builds on Slobodyan and Wouters (2012a). Our extension disentangles the expectations hypothesis of the term structure (EH)…
The homeownership plays an important role in the wealth accumulation, given that the real estate represents over the half of the private households’ wealth. For more than a century, the governments in the market economies have striven to maximize the proportion of households who occupy their own dwellings. The homeowners are thought to be better…
