SEGMENTACIÓN DEL COMPRADOR A DISTANCIA: UN ANÁLISIS DE LOS MEDIOS INTERNET Y TELEVISIÓN /
2005
La aparición de nuevos canales de venta como Internet y la Televisión está generando nuevas oportunidades de mercado para las empresas y está cambiando los hábitos de compra de los consumidores. No obstante, debido a la escasa experiencia de consumidores y empresas en este nuevo medio, la influencia del perfil del consumidor en la decisión de compra en los entornos virtuales es todavía desconocida. El objetivo del presente trabajo es analizar y comparar el perfil sociodemográfico y comportamental de los compradores que utilizan los medios Internet y Televisión, con el fin de identificar los segmentos prioritarios de consumidores para las empresas interesadas en la realización de una campaña…

Information sources used for vacation tourists in tourist destinations
2012
En esta investigación se analiza el uso de las fuentes de información y su incidencia en distintas etapas del proceso de decisión, incidiendo en la búsqueda de información realizada por los turistas en destino. Los resultados muestran que tanto el número y tipo de fuentes de información utilizadas, así como la intensidad de la búsqueda y las decisiones tomadas en destino, es muy diferente del que realizan los turistas antes de llegar a su destino vacacional. Basados en los resultados, como parte de las conclusiones, se exponen ciertas directrices de interés para la gestión empresarial, en relación a la utilización de fuentes de información en los destinos turísticos. This research examines …
Cross-listing, price discovery and the informativeness of the trading process
2003
This paper analyzes the price discovery process of securities that trade at multiple markets with trading sessions that totally or partially overlap. Building on Hasbrouck (1995) information share approach, we introduce a methodology that distinguishes two sources of information asymmetries between markets: trade-related and trade-unrelated informative shocks. This approach determines how much of each market?s relative contribution to the price discovery process during the overlapping period is attributable to its own trading activity. We provide empirical evidence on the contribution of the NYSE in the price discovery process of the Spanish cross-listed stocks during the daily two-hour ove…
¿Cómo se puede mejorar la competitividad de las cooperativas agroalimentarias?
2017
[ES] El entorno de alta competitividad que existe en los mercados agroalimentarios ha incrementado notablemente la presión sobre todos los agentes que operan en ellos. En el caso de las cooperativas, debido posiblemente a su reducida dimensión empresarial, esta cuestión reviste especial importancia puesto que aboca a estas entidades a adoptar cambios que mejoren su competitividad y aseguren la supervivencia. Existe un buen número de trabajos que analizan el papel de distintos aspectos de gestión sobre la competitividad de las empresas en general, sin embargo no se ha abordado el grado de importancia relativa de dichos elementos. El objetivo de este trabajo es establecer una jerarquía en una…
No linealidad y asimetría en el proceso generador del Índice Ibex35
2013
This paper analyzes the behavior of Ibex35 from January 1999 to December 2001, in order to check if it follows a different process from random walk so its return is not a white noise and it can be predictable, against the efficient market hypothesis. For that, a nonlinear generating process of return will be considered and a STAR-APARCH model will be specified. This model allows a nonlinear behavior in the conditional mean and in the conditional variance. The empirical results show that the Ibex35 follows a nonlinear and asymmetric process, both in the conditional mean as in the conditional variance, so the weak-version of efficient market hypothesis is rejected. El trabajo analiza el compo…
Runoff initiation, soil detachment and connectivity are enhanced as a consequence of vineyards plantations.
2017
[EN] Rainfall-induced soil erosion is a major threat, especially in agricultural soils. In the Mediterranean belt, vineyards are affected by high soil loss rates, leading to land degradation. Plantation of new vines is carried out after deep ploughing, use of heavy machinery, wheel traffic, and trampling. Those works result in soil physical properties changes and contribute to enhanced runoff rates and increased soil erosion rates. The objective of this paper is to assess the impact of the plantation of vineyards on soil hydrological and erosional response under low frequency - high magnitude rainfall events, the ones that under the Mediterranean climatic conditions trigger extreme soil ero…
An economic, perception and biophysical approach to the use of oat straw as mulch in Mediterranean rainfed agriculture land
2017
[EN] Soil erosion is a key cause of land degradation in agriculture lands; and it is a worldwide threat that must be solved by means of nature-based strategies to be able to achieve sustainability. The use of mulches can be a solution, but there is a lack of information on long-term effects of the use of straw. Furthermore, little is known about the perception of farmers and the economic cost on the implantation of straw as a conservation measure. Eight paired plots were selected in Sierra de Enguera on an agriculture field to determine the effect of straw cover on soil erosion. Four plots were tilled three times per year (Control) and four plots were not ploughed and 0.125 kg m(-2) y(-1) o…
Volatility transmission patterns and terrorist attacks
2009
The objective of this study is to analyze volatility transmission between the US and Eurozone stock markets considering the effects of the September 11, March 11 and July 7 financial crises. In order to do this, we use a multivariate GARCH model and take into account the asymmetric volatility phenomenon, the non-synchronous trading problem and the crises themselves. Moreover, a graphical analysis of the Asymmetric Volatility Impulse-Response Functions (AVIRF) is introduced, which takes into consideration the crisis effect. Results suggest that there is bidirectional and asymmetric volatility transmission and show the different impact that terrorist attacks had on both markets. El objetivo d…
