{"title":"Impacto del COVID-19 en la eficiencia de fondos de inversión","authors":"Mar Arenas-Parra, Raquel Quiroga-García, Alonso Pérez-Hevia","doi":"10.24309/recta.2022.23.2.04","DOIUrl":"https://doi.org/10.24309/recta.2022.23.2.04","url":null,"abstract":"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.","PeriodicalId":264903,"journal":{"name":"Revista Electrónica de Comunicaciones y Trabajos de ASEPUMA","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130666675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":264903,"journal":{"name":"Revista Electrónica de Comunicaciones y Trabajos de ASEPUMA","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125061143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
