En las últimas décadas, los inversores se han preocupado no sólo de obtener rentabilidad de sus carteras, sino también de casar ese rendimiento con valores éticos relacionados con el mantenimiento del medio ambiente, la responsabilidad social y la gobernanza. Surge así la llamada Inversión Socialmente Responsable, siendo los fondos de inversión socialmente responsables uno de sus instrumentos más importantes. En este trabajo, hemos utilizado el análisis envolvente de datos (DEA) para analizar el impacto del COVID-19 sobre la eficiencia de fondos de inversión socialmente responsables del Reino Unido. Para ello hemos dividido nuestro periodo de estudio en dos: pre-COVID y COVID. De esta forma podremos concluir si hay diferencia respecto a la eficiencia en los fondos según su nivel de sostenibilidad y el periodo analizado. Los resultados obtenidos nos permiten concluir que en el periodo pre-COVID los fondos más eficientes pertenecen al grupo de los de mejor calificación ESG. Si bien este grupo también es el que más se ha visto afectado por la pandemia. Lo contrario se concluye para el grupo de los de menor calificación ESG.Alternate :In recent decades, investors have been concerned not only with obtaining returns on their portfolios, but also with matching these returns with ethical values related to environmental protection, social responsibility and governance. Thus arises the so-called Socially Responsible Investment, being socially responsible mutual funds one of its most important instruments. In this paper, the data envelopment analysis (DEA) has been considered to analyze the impact of COVID-19 on the efficiency of UK socially responsible mutual funds. For this, we have divided our study period into two: pre-COVID and COVID. In this way we will be able to conclude whether there is a difference in the efficiency of the funds according to their level of social responsibility and the analyzed period. The results obtained allow us to conclude that in the pre-COVID period the most efficient funds belong to the group of those with the best ESG rating. Although this group is also the one that has been most affected by the pandemic. The opposite is concluded for the group of those with the lowest ESG rating.
在过去的几十年里，投资者不仅关心从他们的投资组合中获得回报，而且还关心将这种回报与与环境维护、社会责任和治理相关的道德价值观相结合。这就产生了所谓的社会责任投资，社会责任投资基金是其最重要的工具之一。在这项工作中，我们使用数据包络分析(DEA)来分析COVID-19对英国社会责任投资基金效率的影响。为此，我们将研究期间分为两部分:COVID - 19前和COVID - 19后。因此，我们可以根据基金的可持续性水平和分析的时期得出基金的效率是否存在差异。结果表明，在covid - 19之前，效率最高的基金属于ESG评级最高的基金组。然而，这一群体也是受大流行影响最大的群体。对于ESG评分较低的组，则得出相反的结论。备选方案:近几十年来，投资者不仅关心其投资组合的回报，而且还关心这些回报与环境保护、社会责任和治理方面的道德价值相匹配。因此产生了所谓的社会责任投资，社会责任共同基金是其最重要的工具之一。在本文中，数据包络分析(DEA)被考虑分析COVID-19对英国社会责任共同基金效率的影响。为此，我们将研究期间分为两部分:COVID - 19前和COVID - 19后。这样，我们就可以得出结论，根据基金的社会责任水平和所分析的时期，基金的效率是否存在差异。获得的结果使我们得出结论，在covid - 19之前，效率最高的基金属于ESG评级最高的基金组。尽管该集团也影响the one that has been most by the virus。= =地理= =根据美国人口普查局的数据，该镇总面积为，其中土地和(1.)水。

The economy is an open system: it is formed by a large number of economic agents and the environment. Individuals react to external stimuli (from the environment and from other individuals) and internal stimuli in a self-organized way [1]. Self-organized criticality (SOC) [2, 3] supposes that open systems with elements that interact with each other, are organized in the environment of a “stationary” critical state, with no other scales other than those imposed by the size of the system. These critical states are characterized by temporal and spatial power laws. One type of economic phenomenon that could be characterized in this manner is price variations in different markets. These price variations reflect on inflation, which is measured through price indexes (CPI indexes), which can inherit many of the characteristics of the underlying processes. One of the ways in which these characteristics can manifest is through a long memory process with unbounded shocks. On the one hand, there is evidence for different economies that states that the distribution of price variation at the product level is skewed.

El efecto disruptivo de la COVID-19 en la industria turística ha generado nuevas necesidades y motivaciones en los viajes turísticos. Este estudio evalúa los efectos de la pandemia en el perfil y características de los viajes de ocio realizados por los residentes en España. A partir de los microdatos de la Encuesta de Turismo de Residentes del INE, se utiliza el modelo de regresión logística para examinar la relación entre el perfil socioeconómico y demográfico del viajero y las características del viaje con el tipo de destino (internacional o doméstico) para los años 2019-2021. La comparación de los resultados estimados en cada año revela que la motivación del viaje al extranjero difiere significativamente entre los diferentes perfiles de turistas, excepto por razón de género. Los resultados también constatan que las características del viaje fueron significativamente diferentes antes y después de la pandemia. Además, se confirma un cambio significativo en las preferencias del tipo de alojamiento y transporte, junto con una reducción de las diferencias de duración de los viajes a destinos nacionales e internacionales.Alternate :The disruptive effect of COVID-19 pandemic on the tourism industry has generated new needs and motivations for tourist travel.
