The research method was a two-stage exploratory combination of instrument making. In the qualitative part, the purposeful sampling method and theoretical saturation technique were performed. The tools used were to identify semi-structured interviews (with focus groups) and study documents. To ensure the validity and reliability of the study, the Lincoln and Guba evaluation methods were used. In the quantitative part, the research method was a descriptive survey. The statistical population was the economic activists in sports and sports marketing students. According to Cochran’s sample size determination formula, 384 people were considered as the sample. to collect data from the questionnaire of the framework model of the shared economy model in sports with an economic development approach that includes 43 items that have been extracted according to the theoretical foundations and the qualitative part of the research. Eight professors of sports management were used to evaluate the face validity and the carcass model was used for the content validity of the questionnaire questions. (CVR=0.86) and content validity was confirmed. Cronbach's approved alpha was also used. Descriptive statistics and structural equation modeling were used to analyze the data to evaluate the fit of the research model. The results of the research in the qualitative section showed that after examining the Delphi method and performing the first stage, 31 items were identified. In the second stage, 40 items were identified, and in the third stage; Finally, 50 items were identified. The three dimensions of human ecology, fiscal policy, and value-oriented processes emerged as a framework for the model of a shared economy in sports with an economic development approach. And in the quantitative part, the human ecology dimension with a value of 0.71 affects the value-oriented process dimension with a value of 0.65 and the fiscal policy dimension with a value of 0.63 affects the framework for the development of a shared economy in sport. The results also showed that the research model has a good fit. Therefore, it is suggested that the sports organizations' managers pay attention to the factors of this research to implement economic development by emphasizing a shared economy.

This study aims to examine customer retention (CR) from the aspect of customer satisfaction with customer relationship management (CRM), service quality and marketing relations (RM). State-owned bank customers selected the research population in all branch offices in the Madura region, and data were collected through a Likert scale model questionnaire. The results of the path analysis using the structural analysis model (SEM) show that there is an influence of CRM on customer satisfaction; there is an effect of service quality on customer satisfaction; there is an effect of RM on customer satisfaction; CRM through customer satisfaction affects CR; service quality through customer satisfaction affects CR; RM through customer satisfaction affects CR; there is an effect of customer satisfaction on CR on customers. Then the simultaneous test shows that simultaneously RM, service quality, and RM impact customer satisfaction, and the value of coefficient of determination (R-Square) explains that CRM, service quality, and RM can effectively contribute to customer satisfaction. Simultaneously, CRM, service quality, and RM affect CR. CRM, service quality, and RM affect CR mediated by customer satisfaction. CRM, service quality, and RM, through customer satisfaction, can effectively contribute to CR to customers of state-owned bank Regional Offices.

Portfolio optimization aims to minimize risk and maximize return on investment by determining the best combination of securities and proportions. The variance in portfolio optimization models is typically used for a measure of risk. Over the last few decades, portfolio optimization utilizing a variety of risk measures has grown significantly, and many studies have been conducted. Therefore, this paper provides a systematic review of risk measures for portfolio optimization using bibliometric analysis and maps to analyze the evolution and trends of 682 articles published between 2000 and 2022. Throughout this analysis, communication networks among articles, authors, sources, countries, and keywords are explored. Furthermore, a classification of risks and risk measures were presented to demonstrate a comprehensive overview of the field, and the top 50 papers were analyzed to determine which risk measures were most often used in recent studies.

The purpose of our research is to study the impact of financial crisis on Risk premium evolution for a set of emerging countries of MENA (Middle East and North Africa), giving special attention to the appreciation of the local risk premium in addition to the currency risk premium through the study of the dynamics of the financial integration under two assumptions: perfect integration and partial segmentation. At the methodological level, we test a conditional version of the international model of the financial assets ICAPM of De initially proposed by Adler and Dumas 1983 [Adler, M., & Dumas, B. (1983). International portfolio choice and corporation finance: A synthesis. The Journal of Finance, 38(3), 925-984.]. Our analysis is based on the conditional model of regime change of Bekaert and Harvey (1995) [Bekaert, G., & Harvey, C. R. (1995). Time‐varying world market integration. The Journal of Finance, 50(2), 403-444.], we follow the econometric modeling using the Kalman filter and the Markov regime-switching model with variable transition probabilities.

Drawing from the Financial Action Task Force (FATF, G7) recommendations and the Nigeria Anti-Money Laundering Act that provides the penance and dissuasion for crimes in Nigeria, this study sought to interrogate the efficacy of money laundering conviction rate as an instrument of anti-money laundering policy on capital formation in Nigeria. The study is hinged on contemporary deterrence theory. The study adopted the ex-post facto research design and used quarterly data from 1Q 2010 to 4Q 2019, which was sourced from the Nigerian Financial Intelligence Unit (NFIU), Economic and Financial Crime Commission (EFCC) and CBN statistical reports. Hence, Error Correction Model (ECM) was utilized to analyze the data. The findings indicate that the current money laundering conviction rate (MLCR) has a negative and non-significant effect on capital formation in Nigeria. Therefore, the study concludes that the current conviction rate is too weak to deter the act. Hence, it is recommended that the judicial system be rejigged with enabling legislation and autonomy to strengthen it to hasten the trial of such cases and ease conviction of culpable individuals, without necessarily putting innocent victims at jeopardy. Such autonomy should also be granted to the EFCC, ICPC, NFIU etc. and inter-agency synergy should be encouraged.

The Pakistani banking sector has shown tremendous growth in the last two decades and witnessed strategic reforms including the implementation of Basel regulations. The objective of this study is to investigate the effect of Basel capital regulations on the various proxies of the financial performance of the Pakistani commercial banks. This study uses three different proxies to assess the effectiveness of the Basel capital regulations on the financial performance of Pakistani commercial banks from 2006 to 2018 and quantifies the effect of different Basel accords on the banking sector of Pakistan using the dynamic panel data estimation technique. In addition, the effect of the Global Financial Crisis (2008) on the financial performance of Pakistani banks has also been evaluated. The results indicate that Basel II and Basel III capital regulations have affected the banks’ profitability differently. Capital regulations of Basel II have increased the performance while capital requirements of Basel III have not affected the financial performance of Pakistani banks, pointing towards the ineffectiveness of Basel III capital regulations. Besides, there has been no change observed in the financial performance of Pakistani banks during the Global Financial Crisis (2008). Overall, the results of the Generalized Method of Moments (GMM) technique show that Basel capital regulations enhance the financial performance of the Pakistani banking sector.

The purpose of this study was to analyse the effects of profit volatility (X1), income smoothing (X2), corporate governance (X3), and non-performing financing (X4) on profit quality (Y) of sharia banks in Indonesia. The samples of this study were 10 sharia commercial banks in the period of 2012-2018 with 66 panel data that had been tested for outliers and normality. This study used a purposive sampling method, and it used the classical assumption tests, namely multicollinearity, autocorrelation, heteroscedasticity, and normality tests. This study used panel data regression analysis. The results of the study showed that profit volatility was detrimental to profit quality as evidenced by a beta coefficient of 0.0929 and the significance level of 0.1100, income smoothing was detrimental to profit quality as evidenced by a beta coefficient of -0.015 and the significance level of 0.1009, corporate governance had a negative influence on profit quality as evidenced by a beta coefficient of 0.0468 and the significance level of 0.293, non-performing financing was detrimental to profit quality as evidenced by a beta coefficient of -0.0096 and the significance level of 0.9139. The predictive ability of the four variables on profit quality was 16.34% while the remaining 83.66% was influenced by other factors not included in the research model.

This paper critically reviews the main empirical research on goodwill accounting with the purpose of informing and contributing to current debates: the application of a systematic amortisation plus an impairment when required (amortisation model) or an annual impairment-only test (impairment model). Using the main databases (ABI inform, ProQuest Central, Emerald, Science Direct, Scopus and Google Scholar), this critical review highlights the difficulty to resolve doubts at this stage. Arguments for and against the amortisation and impairment models are found. Nevertheless, going back to a systematic amortisation does not seem to be the solution but the impairment test model is eliminated. We also note that there is more room for improvement of the impairment model. Thus, we provide some guidelines and recommendations to improve it. Finally, we find that further investigation can be carried out to fill the gaps identified in the literature and we make recommendations for future research projects.

The paper examined the influence of internal control systems on financial performance of Nigeria’s construction firms. It utilized ridge regression to analyze data from a self-administered questionnaire administered to 305 employees at a company. Internal control had a strong positive impact on financial performance, as evidenced by an R2 of 82.92 percent. In the majority of cases, internal control had positive and statistically significant effects and correlations with financial performance. The positive effects of the control environment and risk assessment were statistically insignificant. It suggests upgrading the control system; the control system must be present and functional.

This study examines the factors affecting audit fees in firms listed primarily in Sub-Saharan Africa countries by focusing on the relationship between ownership structure and audit fees. The study uses an unbalanced panel dataset of 531 observations of non-financial firms collected from annual reports for the years 2005 to 2009. The findings show that audit fees vary with ownership structure. Particularly, the study shows managerial ownership and concentrated ownership are negatively related to audit fees, whereas foreign ownership is related positively to audit fees. This study provides valuable insights on effects of ownership structure on audit fees pricing. Specifically, the study emphasizes that decisions of pricing of audit fees should consider characteristics of the ownership structure of a firm. The study makes contributions to the literature that focuses on the nexus between corporate governance and audit fees. Particularly, the findings provide empirical evidence of impacts of ownership structure on audit fees in Sub-Saharan African context, which is characterized by less developed financial markets and a weak institutional environment relative to developed countries where most studies are conducted.
