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…
Abstract This paper studies the evolution of the monetary policy transmission mechanisms in the US after the financial crisis and the extraordinary monetary stimulus applied since 2008. The implementation of a modified Dynamic Factor Model allows the identification of two different structural scenarios based on the information contained in a large dataset of 110 variables….
We consider quarterly data of the Spanish economy from 1987 to 2013 to establish causal interconnections in a model free manner, using symbolic dynamics and permutation entropy (PE) and establish the exogeneity of adoption of the Euro (in Jan 1999) as the governing mechanism that leads to the key causal impacts on (1) interest rates,…
Abstract Following the ideas of the Tourism Area Life Cycle (TALC) theory, we propose a dynamic econometric model for tourism demand where the reputation effect (the effect of the lagged demand on the current tourism demand) is not constant, but dependent on congestion. We test the model using panel data from Spanish regions during the…
Abstract This paper introduces a novel semi-nonparametric (SNP) distribution that we name Expansion of Moments (ME hereafter). The innovation of this density lies in its polynomials given by the difference between the n-th power of the variable and the n-th moment of the parametric density used as basis. We show that the ME keeps the…
