Economy and diversity of aquaculture production in Bulgaria: status and trends

Aquaculture production in Bulgaria has increased over the last decade, reaching 16 442 tonnes in 2019. Fish production has doubled in comparison with 2007, while that of mussels has increased tenfold. The Bulgarian contribution to EU aquaculture production has been increasing significantly in both volume and value over the years, making up 1.15% of the volume and 1.0% of the value of EU production in 2019. Freshwater aquaculture accounts for 78% of total production. Common carp dominates with about 29.4% (4836 t), followed by rainbow trout with 29.2% (4820 t) in 2019. The cultivation of sturgeon species and caviar production are among the most dynamically developing aquaculture segments. Mariculture in the Black Sea has increased in recent years, with the production of Mediterranean mussel reaching 2932 tonnes in 2019. An average of 405 farms operated during the period 2010-2019. Four regions (Plovdiv, Stara Zagora, Burgas and Montana) account for 50% of the total fish production. Pond aquaculture is the dominant technology used in Bulgaria, and it serves as the basis for numerous other activities, including management of fish stocks in various water bodies mainly for recreational fishing. Approximately 35 net-cage farms currently operate in bigger dams. Recirculating fish farms output made up only 0.15% of the total amount of aquaculture for the period 2010-2019. The aquaculture sector exhibited difficulties in recovering from the financial crisis of 2007-2008, manifested by a slow growth for the period 2010-2014. From 2015 to 2019 there has been a significant growth, manifested in a sharp increase of total revenue and profitability, especially among the larger enterprises in the sector, as well as an increase in the number of employees, and the labour productivity. As a result, in 2019 the registered total revenue per enterprise and total revenue per employee were more than double the respective figures for 2010. The profits of larger enterprises increased more than three times on average, but smaller entities, micro-enterprises with less than 5 employees, operated at the border line between profit and loss. The COVID-19 crisis could have lasting consequences. Despite EUR 1.2 million direct payments in the sector in 2020, there has been a significant drop in the export of aquaculture products. Consumption of fish and other aquaculture products remains low compared to those in the other EU countries.

A quantitative framework for health‐care service quality assessment in India

PurposeThe present situation of COVID-19 pandemic has put the health-care systems under tremendous stress and stringent tests for their ability to offer expected quality of health-care services, as it decides the sustainability and growth of health-care service providers. This study aims to deliver a quantitative framework for service quality assessment in the health-care industry by classifying the health-care service quality parameters into four balanced scorecard (BSC) perspectives.Design/methodology/approachTo determine the service quality for the Indian health-care system, decision-making trial and evaluation laboratory and analytical network process are integrated in a fuzzy environment to contemplate the interaction among BSC perspectives and respective performance measures.FindingsThe results indicate "internal processes” perspective assumes the key role within BSC perspectives, while performance measures "nursing staff turnover” and "staff training” play the key roles. The results also signify that "patient satisfaction” is the most vital issue and can be strongly influenced by measures belonging to the "learning and growth” perspective. In "learning and growth” perspective, "staff training” is the most decisive criteria, very highly influencing "patient satisfaction”, highly influencing "profitability,” "change of cost per patient (both in and out patients)” and "outpatient waiting time” while moderately influencing "staff satisfaction,” "bed occupancy” and "nursing staff turnover”. Moreover, "staff training” criteria have a positive influence on "nursing staff turnover.”Originality/valueThe contributions of this study are in two folds in the domain of quantification of service quality for the health-care system. First, it delivers an assessment framework for Indian health-care service quality. Second, it demonstrates an application of the framework for a case situation and validates the proposed framework.

Working capital and firm performance: role of COVID-19 disruption

PurposeThis study examines the performance effect of working capital for a large sample of Indian manufacturing firms in light of supply chain disruption, i.e. the COVID-19 pandemic.Design/methodology/approachThis study is based on secondary data collected from the Prowess database on Indian manufacturing firms listed on the Bombay Stock Exchange (BSE) 500. Panel data regression analyses are used to estimate all models. Moreover, this study has employed robust standard errors to consider for heteroscedasticity concerns.FindingsThe results challenge the current notion of working capital investment and reveal that higher working capital has a positive and significant impact on firm performance. Further, it highlights that Indian manufacturing firms suffered financially post-COVID-19 as they significantly lack the working capital to run day-to-day operations.Originality/valueThis research contributes to the scant literature by examining the association between working capital financing and firm performance in light of the COVID-19 pandemic, representing typical developing economies like India.

FACTORS PRECEIVED TO INFLUENCE THE PERFORMANCE OF PUBLIC SECTOR EMPLOYEES WITH MEDIATING EFFECT OF EMPLOYEES SATISFACTION, A CASE STUDY OF CIVIL DEFENCE DIRECTORATE

In developing countries like Pakistan, mostly the public sector departments give not as much of focus on the performance / capacity building as well as the satisfaction of the employees, the research was conducted to know the influence of the factors perceived on the performance of public sector employees by increasing satisfaction and for this purpose the Civil Defence Department was selected. The study was conducted on the mixed method approach in which both qualitative and quantitative methodologies were adopted to know the responses of the employees of the Civil Defence Department regarding research objectives. Questionnaires, both in open ended and close ended format were distributed among 100 employees of the Civil Defence Department as per the availability of the skeleton staff during COVID-19. The hypotheses were equipped to recognize the significance relationship of variables as well as statistical analysis was applied through SPSS to examine the acceptance or rejection of the hypothesis. Hence, the result instigated that factors perceived in this study have significance influenced on the performance and satisfaction of the public sector employees.

Freire 2.0: Pedagogy of the digitally oppressed

This paper reinvents Freire's concepts of ‘banking education' and ‘literacy' within the context of the exponential growth of digital instruction in the 21st century. We argue that digital learning (i.e. online or technology enhanced) undoubtedly increases access to education globally, but also can intensify some of the worst problems described in Freire's banking model. Accordingly, we draw from postdigital theory to scrutinize the specific structures and functions of common digital Learning Management Systems (LMSs) used by schools (i.e. Blackboard and Google Classroom) to reveal a type of learning that further exacerbates the teacher-student dichotomy without liberating either party in a Freirean sense. We then use a Foucauldian lens to bring an awareness to how the accelerated use of these systems at scale, in part caused by the COVID-19 pandemic, can further entrench a data-driven, dehumanized educational experience which increases corporate profitability perhaps over the needs of students. Finally, we use these insights to modernize Freire's concept of ‘literacy' by building on Critical Medial Literacy (CML) in order to help educators address LMSs, (mis)information facilitated by digital content, and schooling in a (post)pandemic and postdigital world.

Towards Digital Twin Maintenance Management of Health Facilities in Nigeria: The Need for Maintenance Documentation

The COVID-19 pandemic that recently broke forth revealed the waning state of a considerable number of healthcare facilities, especially in unindustrialized territories. This is of great concern, and it has become pertinent to identify determinants of efficient maintenance management in developing countries. There is an inefficient maintenance management of hospital buildings due to a low level of maintenance documentation, which otherwise would have facilitated the adoption of digital twin (DT) technology. The existing maintenance management frameworks and models have not explored and evaluated maintenance documentation as an all-inclusive construct. Hence, this study was aimed at emphasizing the significance of maintenance documentation for its adoption as one of the main determinants of efficient maintenance management, with a view to attaining the DT maintenance management of hospital buildings in Nigeria. After a theoretical review on existing studies around documentation, the software documentation concept was used to conceptualise this observed gap in maintenance management models for public hospital buildings in developing countries. This critical review, which forms part of an ongoing study, asserts that maintenance documentation is a major construct for efficient maintenance management and a prerequisite for the adoption of DT in the management of healthcare constructed facilities in developing countries.

Women's Participation in Firms' Management and Their Impact on Financial Performance: Pre-COVID-19 and COVID-19 Period Evidence

At a time when gender equality is a key priority of all international organizations, this paper can be considered a remarkable contribution to the role of women executives in firms' performance. More specifically, this study focuses on the effect of women holding positions of responsibility on firms' performance worldwide. For the purposes of our research, we applied cross-sectional and panel data analysis for all sectors at an international level from 2019, the year preceding the breakout of the pandemic crisis, to 2021, while the indicators used to measure the participation of women in executive positions are classified as ESG indices. The empirical analysis findings end up showing that the participation of women in executive positions positively affects firms' performance over time, while there is no material change observed before and during the COVID-19 pandemic period. More specifically, when the percent of women processing job positions of responsibility increases by 10%, then the index of profitability will increase from 1.4% to 1.8%, regardless of the measurement of female participation in executive positions used. The results of this study constitute a remarkable contribution to the promotion of the creative economy, the progress of societies, and sustainable development. The research's outcome can be primarily used by policymakers drawing up policies for achieving gender equality in the labor market and workplaces and by shareholders and firms' managers in order to trust females in executive positions in favor of their firms' financial performance. The current study is unique in that it focuses on the period before and during the COVID-19 period, as a period of high volatility in economic activity worldwide, while the sample includes firms from large and mid-cap companies belonging to developed and emerging markets. The above approach will contribute to providing more credible information related to the role of women executives in firms' performance.

Mobilizing Social Media Data: Reflections of a Researcher Mediating between Data and Organization

This paper examines the practices involved in mobilizing social media data from their site of production to the institutional context of non-profit organizations. We report on nine months of fieldwork with a transnational and intergovernmental organization using social media data to understand the role of grassroots initiatives in Mexico, in the unique context of the COVID-19 pandemic. We show how different stakeholders negotiate the definition of problems to be addressed with social media data, the collective creation of ground-truth, and the limitations involved in the process of extracting value from data. The meanings of social media data are not defined in advance;instead, they are contingent on the practices and needs of the organization that seeks to extract insights from the analysis. We conclude with a list of reflections and questions for researchers who mediate in the mobilization of social media data into non-profit organizations to inform humanitarian action. © 2023 ACM.

The Asymmetric Impact of COVID-19: A Novel Approach to Quantifying Financial Distress across Industries.

This paper assesses corporate financial distress in terms of liquidity and risk of insolvency due to the COVID-19 pandemic. We develop a novel multivariate approach to obtain monthly data on industry turnover, exploiting real time data to capture the atypical character of industry-specific disturbances. By combining the estimated set of industry revenue shocks with pre-pandemic financial statements, we quantify the impact of the pandemic on the risk of insolvency in the EU non-financial corporate sector. Our definition of risk of insolvency takes into account not only the equity position of firms, but also risks relating to overindebtedness. The analysis controls for firms that were financially vulnerable already before the pandemic, thus being prone to become at risk of insolvency also in absence of the COVID-19 turmoil. We find that, for the EU as a whole, 25% of firms exhausted their liquidity buffers by the end of 2021 (a practical cut-off date of the analysis, not an assumed end of the pandemic). Furthermore, 10% of firms which were viable before the pandemic, appear to have shifted into risk of insolvency as a result of the COVID-19 crisis. The magnification of financial vulnerability in the hardest-hit industries mainly occurs among firms with no legacy issues, i.e. firms with positive profitability pre-pandemic. A similar finding is reported for some of the hardest-hit countries, such as Italy and Spain. In other countries, such as Germany or Greece, the magnification of financial vulnerability mainly occurs among firms with negative profitability pre-pandemic.

Government policy response to COVID-19 and bank performance: a comparison between Islamic and conventional banks

PurposeThis study aims to examine the joint impact of the COVID-19 pandemic and the government response on the performance of Islamic and conventional banks. Design/methodology/approachData were collected from a sample of 94 conventional and 14 Islamic banks in Indonesia from March 2020 to September 2021. The system generalized methods of moments estimation is used to analyze the data. FindingsThis study finds robust results regarding the negative impact of the COVID-19 pandemic and the positive effects of government responses to COVID-19 pandemic on bank performance in Indonesian banking. Moreover, in line with the rise in confirmed COVID-19 cases, a higher government policy responses index improves bank performance, both in conventional and Islamic banks. Practical implicationsThis paper highlights the importance of the government policy responses index to absorb the negative impact of the COVID-19 outbreak on banking performance. Originality/valueThis paper provides novel insights into the joint impact of the COVID-19 pandemic and government responses to COVID-19 pandemic on bank performance between conventional and Islamic banks.

Farmers' Profitability through Online Sales of Organic Vegetables and Fruits during the COVID-19 Pandemic-An Empirical Study

The purpose of this research is to empirically identify the association of the IT literacy of farmers and their profitability through online sales of fresh organic fruits and vegetables during the COVID-19 pandemic. The methodology used in the research is quantitative in nature. A closed-end questionnaire has been used as a survey tool to collect data from Indian farmers. The farmers' IT literacy and attitudes towards organic farming are independent variables, and the frequency of sales of products through online stores and farmers' profitability are the dependent variables. The researcher has attempted to study how the outbreak of COVID-19 has moderated the relationship between the independent and dependent variables. The sample size is 271 farmers who sell their products through online stores. The findings reveal that the farmers' attitude towards organic farming and their IT literacy correlate with the profitability of online sales. Further, the outbreak of the COVID-19 pandemic has moderated the relationship between both the dependent and independent variables. This research will help the government in formulating policies for facilitating farmers to sell their produce through online modes. The study could be further extended by collecting data from farmers from different Asian countries and comparing the results with those of the present research findings.

The impact of organizational culture and total quality management on the relationship between green practices and sustainability performance

PurposeThis study aims to examine the direct and indirect effects of organizational culture (OC) and total quality management practices (TQMPs) on the relationship between green practices (GPs) and sustainability performance (SP) by using structural equation modeling (SEM) analysis.Design/methodology/approachThis study proposed a conceptual research model of the relationships and formulated six hypotheses. This study used a structured questionnaire based on previous studies to collect relationship data to test these hypotheses, and 441 full-time managers from various US businesses responded. The complete and valid survey responses were then tested against the hypotheses using IBM SPSS Statistics and SEM-AMOS.FindingsResults supported the relationships proposed in the research model. They indicated that a strong supporting OC and TQMPs might improve positive SP and GPs. Additionally, the more managers are aware of their companies' GPs, the more likely they will feel positive about the organization's SP.Research limitations/implicationsA larger sample size to ensure statistically minimum representation in several major industries would better validate the findings and help identify significant differences in industry-specific OCs, TQMPs, GPs and SPs. Similarly, ensuring a varied geographical representation (both within the USA and internationally) would help determine if the findings vary according to the respondent's location. Furthermore, collecting the data during Year 1 of the COVID-19 pandemic may have skewed the results. Thus, once the working environment has been normalized, the survey should be repeated to determine if the findings are valid post-pandemic.Practical implicationsThe findings of this study provide important strategic guidance for managers who work to balance the implementation of corporate GPs and the triple bottom line dimensions of SP. For practitioners, the results showed that companies could accomplish both profitability and sustainability if they are willing to continuously pay attention to environmental issues and strategically invest in cost-efficient and eco-friendly initiatives.Originality/valueTo the best of the authors' knowledge, this research is one of the first to explore how OC and TQMPs, directly and indirectly, affect the relationship between GPs and the triple bottom line dimensions of SP. These results imply that OC and TQMPs have a significant indirect impact on the relationship between GPs and the SP dimensions.

The Moderating Role of Good Corporate Governance: The Influence of Capital Structure, Profitability, Dividend Payment and Inflation on The Value of Mining Companies in Indonesia: Acces la Success

The objectives of this research include: (1) examining and analyzing the effect of capital structure, profitability, dividend payments and inflation on the value of mining companies;(2) examining and analyzing the moderating role of Good Corporate Governance (GCG) on the effect of capital structure, profitability, dividend payment and inflation on the value of mining companies listed on the IDX. The population of this study is all mining sector companies listed on the IDX for the period 2014-2020. The purposive sampling method is used as the sampling technique. The total population is 49 companies and the number of samples that meet the criteria are 44 companies. The research period is 7 years, so the total number of observations is 308 data (pooled data). The Moderated Regression Analysis (MRA) is used as the analysis method. The result is as follow: (1) capital structure has a negative significant effect on firm value;(2) profitability has a positive significant effect on firm value;(3) dividend payment has no significant effect on firm value;(4) inflation has a negative significant effect on firm value;(5) GCG has a moderating effect on the influence of capital structure, profitability and inflation on firm value, with the type of Quasi Moderating, whereas on the influence of dividend payments on firm value, it was the type of Pure Moderating.

Analyzing The Profitability Of Top-Rated Banks In The World In Light Of COVID-19

We analyze the impact of COVID-19 on the profitability of top-rated banks in the world using a comprehensive list of bank-specific ratios under post-lasso regressions based on GLS, FGLS and WLS techniques. While size and loans do not materially impound on profitability, a squeeze in the positive impact of asset utilization for all profitability metrics is conspicuously noted. COVID-19 induced declines in the negative impact of total impairment charges and provisions are noted for ROA and NIM while COVID-19-induced hike in the cost-to-income ratio is found for ROE. Findings also demonstrate that policy responses initiated during the crisis did not boost the profits of banks. From a policy perspective, sharing economy could manifest as a contemplated business model for banks, should the world relapse into another form of pandemic-related crisis. © 2023 World Scientific Publishing Company.

PREDICTIVE ABILITY OF FINANCIAL AND NON-FINANCIAL PERFORMANCE FOR FINANCIAL STATEMENT PUBLICATION TIME FRAME: MODERATING ROLE OF COVID-19 PANDEMIC

Objetivo: Este estudo examinou a capacidade de desempenho financeiro e nao financeiro na previsäo do tempo de publicaçao de relatórios financeiros, moderada pela pandemia da COVID-19. Referenciái teórico: A teoria dos sinais postula que a administraçâo desempenha um papel crucial no fornecimento de informaçöes as partes interessadas sobre as condiçöes da empresa (Brigham & Houston, 2001). De acordo com Spence (1973), as empresas estao motivadas a fornecer informaçöes relevantes as partes interessadas. Se as condiçöes de desempenho sao boas, a empresa tende a acelerar o processo de apresentaçao de demonstraçöes financeiras. Por outro lado, se o desempenho for ruim, há uma tendencia a atrasar a publicaçao dos relatórios financeiros. O longo período de tempo para a publicaçao de relatórios financeiros pode indicar más noticias que a empresa tem, de modo que ela ainda tem que publicar as noticias para o público. Scott (2015) sugere que quando os gerentes souberem que há noticias desfavoráveis sobre a condiçao da empresa no futuro, evitarao publicar estas informaçöes ou pelo menos atrasaräo a apresentaçao das demonstraçöes financeiras. Método: O desempenho financeiro foi medido por quatro indicadores: lucratividade, liquidez e solvencia. Enquanto isso, o desempenho nao financeiro variável foi medido pelo indice de boa governança corporativa (GCG) e pela reputaçao dos auditores. O modelo proposto foi testado com base nos dados quantitativos coletados de 156 empresas de manufatura listadas na Bolsa de Valores da Indonesia (IDX) a partir de 2018 e 2020. A análise de regressao múltipla foi realizada para analisar e interpretar os dados. Resultados e conclusao: O resultado indica que a solvencia, a boa governança corporativa e a reputaçao do auditor foram preditores significativos do período de publicaçao do relatório financeiro. Entretanto, a capacidade preditiva de rentabilidade e liquidez no prazo de publicaçao nao foi considerada significativa. Além disso, os resultados mostram que a pandemia da COVID-19 modera a capacidade de rentabilidade e boa governança corporativa na previsao do prazo de publicaçao. Implicates da pesquisa: O indicador de desempenho financeiro e nao financeiro dá resultados diferentes na previsäo do RWPLK das empresas de manufatura na Indonesia. ROA e CR nao sao capazes de prever o RWPLK, mas DER, GCG, KAP sao capazes de prever o RWPLK. O papel da pandemia COVID-19 foi capaz de moderar a capacidade de ROA e GCG em prever o prazo para publicaçao de relatórios financeiros, mas foi incapaz de moderar a capacidade de CR, DER e KAP em prever o RWPLK. Originalidade/valor: O presente estudo fornece a primeira evidencia empírica sobre o papel moderador da pandemia COVID-19 na capacidade preditiva do desempenho financeiro e nao financeiro para o prazo de publicaçao das demonstraçöes financeiras.Alternate :Purpose: This study examined the ability of financial and non-financial performance in predicting financial reports publication time frame as moderated by the COVID-19 pandemic. Theoretical framework: Signal theory postulates that management serves a crucial role in providing information to stakeholders regarding the condition of the company (Brigham & Houston, 2001). According to Spence (1973), companies are motivated to provide relevant information to stakeholders. If the performance conditions are good, the company tend to speed up the process of presenting financial statements. Conversely, if performance is poor, there is a tendency to delay the financial reports publication. The long span of time for the publication of financial reports can indicate bad news that the company has so that it has yet to publish the news to the public. Scott (2015) suggests that when managers know there is unfavorable news about the condition of the company in the future, they will avoid publishing this information or at least delay the presentation of financial statements. Method/design/approach: Financial performance was measured by four indicators: profita il ty, liquidity and solvency. Meanwhile, variable non-financial performance was measured by the index of good corporate governance (GCG) and auditor reputation. The proposed model was tested based on the quantitative data collected from 156 manufacturing companies listed on the Indonesia Stock Exchange (IDX) from 2018 and 2020. The multiple regression analysis was performed to analyze and interpret the data. Results and conclusion: Result indicates that solvency, good corporate governance, and auditor reputation were significant predictors of the time span of financial report publication. However, the predictive ability of profitability and liquidity on the publication timeframe was found to be not significant. Furthermore, the results show that the COVID-19 pandemic moderates the ability of profitability and good corporate governance in predicting the publication timeframe. Research implications: Financial and non-financial performance indicator gives different results in predicting the RWPLK of manufacturing companies in Indonesia. ROA and CR are not able to predict RWPLK, but DER, GCG, KAP are able to predict RWPLK. The role of the COVID-19 pandemic was able to moderate the ability of ROA and GCG in predicting the timeframe for publication of financial reports, but was unable to moderate the ability of CR, DER and KAP in predicting RWPLK. Originality/value: The present study provides the first empirical evidence on the moderating role of the COVID19 pandemic on the predictive ability of financial and non-financial performance for financial statement publication time frame.

How Does the Degree of Competition in an Industry Affect a Company's Environmental Management and Performance?

Environmental management, which was recognized as a functional part of corporate management, has recently been recognized as a strategic element of all business activities. It can be defined as a series of management activities to improve environmental performance throughout the business process and simultaneously achieve profitability and sustainability. Accordingly, businesses are now abandoning the existing management philosophy that economic and environmental feasibility are inevitably in conflict and establishing strategies and methods to achieve both. Meanwhile, industry affects the business performance of individual companies. Since the performance of a company tends to be influenced by the intensity of competition in an industry, it is necessary to analyze the structural factors that determine the intensity of competition in an industry in order to predict the future performance of a company. Therefore, we studied how environmental management affects corporate performance given the level of industry competition. The results are as follows. First, environmental management positively impacts corporate performance. Second, a high level of competition within an industry moderates the relationship between environmental management and corporate performance. By verifying the influence of the industry to which a company belongs, that is, the level of competition within the industry, we confirm that a company's environmental management can be used strategically to gain a competitive advantage. With the finding that the impact of a company's environmental practices differs by industry in line with the degree of competition, we expect this study to be helpful for future research into strategic ESG activities.

Disclosures for slavery accounting concerning SDG 8 and corporate attributes: a study on the banking industry of Bangladesh

With the continuous adoption of sustainable development goals by all countries, there is a rising demand for implementing and disclosing related information by companies. This paper aims to find an idea about the nature of reporting practices related to slavery by listed banking companies of Bangladesh and the relationship between reporting practice and organizational attributes. Existing literature provides the foundation of this study. Annual reports from 2016 to 2021 were collected from the company websites, and content analysis was used to determine the nature and extent of slavery reporting;an index was developed based on content analysis. Independent variables were determined based on the current literature review. Statistical tools, including the test of multicollinearity, heteroscedastic, correlation, and linear regression and panel data analyses were used to determine the fitness of the model and the impact of independent variables on the dependent variable. Content analysis showed a clear picture of the consciousness about slavery accounting as all of the companies reported a minimum of three components of selected targets from SDG8. The evidence says that the quality and quantity of slavery reporting are improving yearly. A satisfactory correlation was found among the variables. Some variables, such as ownership nature, Board Size, etc., have a positive impact, and insignificant impact was found for Age and leverage on slavery disclosure. This paper only examines the banking industry, and it assesses only a few targets of SDG 8. Thus the results obtained from the study may not be similar to other companies. Data collection also has limitations;our target was to study till 2022 but some information requirements of few companies were not available on websites. This research paper is the first attempt to determine the nature of slavery accounting in Bangladesh. It will encourage business organizations to extend their reporting on slavery and SDGs.

Clean Energy Action Index Efficiency: An Analysis in Global Uncertainty Contexts

Climate change, the scarcity of fossil fuels, advances in clean energy, and volatility of crude oil prices have led to the recognition of clean energy as a viable alternative to dirty energy. This paper investigates the multifractal scaling behavior and efficiency of green finance markets, as well as traditional markets such as gold, crude oil, and natural gas between 1 January 2018, and 9 March 2023. To test the serial dependency (autocorrelation) and the efficient market hypothesis, in its weak form, we employed the Lo and Mackinlay test and the DFA method. The empirical findings showed that returns data series exhibit signs of (in)efficiency. Additionally, there is a negative autocorrelation among the crude oil market, the Clean Energy Fuels Index, the Global Clean Energy Index, the gold market, and the natural gas market. Arbitration strategies can be used to obtain abnormal returns, but caution should be exercised as prices may increase above their actual market value and reduce the profitability of trading. This work contributes to the body of knowledge on sustainable finance by teaching investors how to use predictive strategies on the future values of their investments.

Covid-19 and the profitability of the banking sector of the Lima Stock Exchange

The COVID-19 pandemic has been an unforeseen event that has generated serious and negative consequences in a variety of sectors, including business. Thus, there is a large knowledge gap linked to the identification of the specific effects that the pandemic has generated in companies that provide essential services for the population. This research aimed to determine the impact of the COVID-19 pandemic on the profitability of the banking sector of the Lima Stock Exchange. An applied type of work, with a quantitative approach, correlational scope and non-experimental design was proposed. The hypothesis formulated was verified, since, based on the statistical and comparative data generated based on the economic and financial profitability of the entities studied, it can be affirmed that the Covid-19 pandemic had a negative effect on the profitability of the banking sector of the Lima Stock Exchange.
