This paper explores the state of the art in the cryptocurrency literature, with a special emphasis on the links between financial dimensions and ESG features. The study uses bibliometric analysis to illustrate the history of cryptocurrency publication activity, focusing on the most popular subjects and research trends. Between 2014 and 2021, 1442 papers on cryptocurrencies were published in the Web of Science core collection, the most authoritative database, although only a tiny percentage evaluated ESG factors. One of the most common criticisms of cryptocurrencies is the pollution derived from energy consumption in their mining process and their use for illicit purposes due to the absence of effective regulation. The study allows us to suggest future research directions that may be beneficial in illustrating the environmental effect, studying financial behavior, identifying the long-term sustainability of cryptocurrencies, and evaluating their financial success. This study provides an in-depth examination of current research trends in the field of cryptocurrencies, identifying prospective future research directions.

Since the Bologna Declaration, improving the efficiency and transparency of the systems of higher education has become one of the principal challenges for all European countries. In fact, the establishment of evaluation processes in programmes and institutions is a current practice. For this purpose, several mechanisms of evaluation are being developed with the aim of accurately measuring the performance of these institutions. This paper applies the data envelopment analysis (DEA) methodology to assess the performance of the departments of the University of Zaragoza (Spain). The selected indicators concern both the teaching and the research activity of these departments. The results reveal the departments that carry out these activities more efficiently according to the variables included in each analysis. Finally, I discuss the existence of differences in the strengths and weaknesses among departments covering different areas, suggesting several initiatives aimed at improving their performance in the light of current Spanish higher education reform.

The objective of this study is to analyze, from a multi-theoretical framework, whether the managers of the Spanish National Sports Federations (NSFs) apply earnings management using accounting accruals as a measure of managerial discretion; secondly, whether these practices are associated with both the level of dependence on external resources, and the economic and financial control mechanisms exercised by the Superior Sports Council (Consejo Superior de Deportes, CSD) for the granting of public subsidies. The study provides evidence that long-term debt levels and the size of sports federations are determinants of earnings management, with a more accentuated relationship in the case of Olympic and Paralympic sports federations.

This paper analyses the effectiveness of the financial control system implemented by the Spanish professional football League in 2015 as a tool to improve the governance of clubs in the first and second divisions as well as its probable impact on competition. Classic financial ratios are used to analyse the financial situation of the clubs both before and after the implementation of the Regulation, as well as during the first season affected by the COVID-19 pandemic. Next, the Herfindahl index is calculated to measure the concentration in the distribution of the main funding sources and is incorporated as a dependent variable in a regression model. Although a cause–effect relationship is not certain, the results suggest that the economic control measures imposed by LFP have contributed to improving the financial situation of Spanish football in the short term, but may promote imbalances between clubs that undermine the sustainability of the current management model and, therefore, of the competition system. Unlike in other sectors, the football business requires more competition to maximise profits. In this context, it would be advisable to reach agreements between clubs to weaken the bargaining position of footballers. The paper shows the effect of the intervention of a regulatory body, in this case, LFP, in the functioning of a competitive market.

Purpose: The purpose of this paper is to analyse the performance of Spanish banking entities between 2009 and 2013, a period marked by the reform of the banking system with a large number of mergers and integrations.Design/methodology/approach: First, efficiency is measured applying the data envelopment analysis (DEA) methodology and, then, the Malmquist index is calculated to assess its evolution.Findings: The results show that most of the entities have improved their performance from the production approach. However, from the intermediation approach, the efficiency of the sample has deteriorated, which raises questions about the sustainability of the traditional banking business when the current credit restriction strategy is long lasting.Practical implications: The comparative analysis demonstrates that, after the deep reforms carried out in Spain, the banking entities maintain similar efficiency rankings to those they had at the beginning of the period analysed. This shows that the reform has created new groups that operate adequately, avoiding the closing of institutions. Despite the better rationalisation of the available resources, the outlook for Spanish banks remains unclear in the current macroeconomic context, which does not favour the banking business.Originality/value: The study contributes to the literature on the Spanish banking system because it adds new empirical evidence about its restructuring and it applies a DEA model to a sample before and after mergers. The authors discuss theoretical and managerial implications and offer suggestions for future research on this field.
