This article presents an analysis of the state of the art on the relationship between tourism, sustainability and competitiveness (TSC); moreover, the analysis also includes a focus on tourism destination (TSCD). To that end, information on the publications in these fields from recent years was sourced from the Web of Science database. In addition, the VOSviewer software program was used to enable a more in-depth bibliometric study, allowing the results to be clustered by authors, institutions, countries, and journals. The study carried out revealed that 808 articles have been published on aspects relating to TCS and 409 regarding TSCD. The results obtained underscore the greater scientific output on aspects related to sustainability than on aspects related to competitiveness and also that there has been a significant and exponential increase in both cases in recent years. These three fields of study (tourism, sustainability and competitiveness) are rarely combined in the literature, highlighting the lack of a comprehensive overview of this trinity. The evidence reported here suggest that the trend identified represents a future line of work for the coming years.

The electricity sector was negatively impacted by the coronavirus disease (COVID-19), with considerable declines in consumption in the initial phase. Investors were in turmoil, and stock prices for these companies plummeted. The aim of this paper is to demonstrate the significant negative influence of the pandemic on abnormal returns for the electricity sector, specifically for traditional and renewable companies and the influence of ESG scores, using the event study approach and multi-variate regressions. Our results show that the pandemic indeed had a negative impact on the electricity sector, with renewable electricity companies suffering a sharper decline than traditional ones. Moreover, we find that ESG pillar scores affected electricity companies differently and are sector-specific. For renewable electricity companies, the returns were positively influenced by the environmental ESG scores and negatively by governance ESG scores.

This article analyzes state-of the art studies that focus on the economic aspects (EA) of municipal solid waste (MSW) management systems, including an analysis of articles that have developed methodologies for economic analysis (MEA), as well as those which study the economic analysis of the externalities or external impacts related to these systems. The aim of this study was to determine the trends in research and critical points based on the literature available in the Web of Science database from 1980 to 2019. First, we present the statistics and general trends, then perform an in-depth bibliometric study using the VOSviewer software, which allows the results to be grouped according to references, authors, institutions, countries, and journals. The study showed that 563 articles about the economic aspects have been published, 229 about methodology development, and only 21 considered the methodologies for analyzing externalities generated by the MSW management systems. In general, there is great interest in the economic analysis of the systems and technologies that deal with transforming waste into energy.
