Purpose: – This paper aims to empirically examine the quality of corporate governance (CG) practices in Egyptian-listed companies and their impact on firm performance and financial distress in the context of an emerging market such as that of Egypt.Design/methodology/approach: – To assess the level of CG practices at a given firm, the current study constructs a corporate governance index (CGI) which consists of four dimensions: disclosure and transparency, composition of the board of directors, shareholders’ rights and investor relations and ownership and control structure. Based on a sample of 86 non-financial firms listed on the Egyptian Exchange, the effects of CG on performance and financial distress are assessed. Tobin’s Q is used to assess corporate performance. At the same time, the AltmanZ-score is used as a financial distress indicator, as it measures financial distress inversely. The bigger theZ-score, the smaller the risk of financial distress.Findings: – The overall score of the CGI, on average, suggests that the quality of CG practices within Egyptian-listed firms is relatively low. The results do not support the positive association between CG practices and financial performance. In addition, there is an insignificant negative relationship between CG practices and the likelihood of financial distress. The current study also provides evidence that firm-specific characteristics could be useful as a first-pass screen in determining firm performance and the likelihood of financial distress.Research limitations/implications: – The sample size and time frame of our analysis are relatively small; some caution would be needed before generalizing the results to the entire population.Practical implications: – The findings may be of interest to those academic researchers, practitioners and regulators who are interested in discovering the quality of CG practices in a developing market such as that of Egypt and its impact on financial performance and financial distress.Originality/value: – This paper extends the existing literature, in the Egyptian context in particular, by examining firm performance and the risk of financial distress in relation to the level of CG mechanisms adopted.

Purpose: Using data on 51 firms traded in the Egyptian Exchange from 2014 to 2016, this paper aimed to assess the efficiency of corporate governance (CG) and intellectual capital (IC) practices and to explore their influence on the probability of a firm's financial distress.Design/methodology/approach: The relative efficiency of CG and IC practices has been measured under the Malmquist data envelopment analysis model. A modifiedZ-score model was applied to assess firms' financial distress.Findings: The Wilcoxon signed-rank test revealed almost insignificant evidence regarding the improvement of CG and IC efficiency over the study period. The efficiency score of CG practices had no impact on the likelihood of financial distress. However, the efficiency score of IC negatively affected the probability of financial distress.Research limitations/implications: The integration of data envelopment analysis with Tobit regression was required for identifying the significant drivers of efficient CG and IC.Practical implications: The findings shed light on the role of CG and IC in alleviating the degree of financial distress in Egypt as an emerging market, especially the need to raise firms' compliance with the Egyptian CG code from a voluntary to mandatory status.Originality/value: This study, using Malmquist data envelopment analysis, is among the first attempts to assess the relative efficiency of CG and IC practices and their effects on financial distress.

Purpose: The efficient use of organizational resources is integral to the existence of prime firms. This study, using Malmquist data envelopment analysis (DEA), aims to assess in the level of operational and financial efficiency and its determinants for ensuring and sustaining excellent performance in 33 Egyptian private hospitals.Design/methodology/approach: This study adopted a Malmquist DEA approach to assess the changes in operational and financial efficiency in Egyptian hospitals. Tobit regression was also used to identify the significant variables affecting their efficiency. In addition, a sensitivity analysis is carried out for model validations.Findings: Out of 33 hospitals, 17 were found inefficient due to the decline in their technical efficiency. Moreover, the total value of the software programs and operational expenses and the total number of employees are common factors affecting both operational and financial efficiency. In addition, the number of physicians significantly affects the hospital's financial efficiency.Practical implications: The study sheds light on the value of using DEA to assess efficiency. DEA in the context of emerging economy such as Egypt's can be a useful tool for decision-makers and practitioners in identifying and addressing performance weaknesses and thus supports continuous improvement in performance.Originality/value: Several studies have adopted the DEA approach to assess the overall efficiency of hospitals in Europe and the United States. However, in the MENA region, these studies are uncommon. This study is thought to be one of the earliest attempts to assess hospitals' efficiency in Egypt.

Purpose: This study assesses the impact of corporate social responsibility (CSR) practices on the relative efficiency of conventional and Islamic Egyptian banks in the period 2012–2018.Design/methodology/approach: A three-stage approach is adopted. First, data envelopment analysis (DEA) is used to assess the relative efficiency of Egyptian banks. Second, a CSR index is designed and used to assess the extent of aggregate CSR practices in Egyptian banks, together with their sub-dimensions. Third, a Tobit regression model is used to examine the impact of CSR on the technical efficiency of these banks.Findings: There is no statistically significant difference between conventional and Islamic banks as regards their purely technical efficiency. Egyptian banks, on average, have achieved a medium score in their practices of CSR and conventional and Islamic banks have not shown significant differences, except in 2018. Moreover, the aggregate CSR practices positively affect the technical efficiency of Egyptian banks. The practices of the CSR sub-dimensions, apart from the community sub-dimension, also affect the banks' technical efficiency.Practical implications: The legislative institutions and the Central Bank should enhance CSR practices in Egyptian banks, particularly the practices related to customers and the community, in order to enhance the purely technical efficiency of these banks.Originality/value: The paper is original in investigating the impact of CSR on banks' relative efficiency in Egypt.

Purpose: This paper aims to investigate the impact of intellectual capital (IC) as a mediator variable on the association between corporate governance (CG) practices and firm performance. This study also examines bi-causality linkages between these variables.Design/methodology/approach: The designated corporate governance index and the value-added intellectual coefficient method were used to assess the level of CG practices and the performance of IC. Tobin’s Q (TQ) and operating efficiency ratio were used to measure firm performance.Findings: The aggregate CG score has a significant positive impact on the IC and the two measures of firm performance. However, the IC has only a partial mediation effect on the relationship between the aggregate corporate governance score and a firm’s operational efficiency ratio. The IC has partial and full mediation effects in the relationship between the sub-dimensions of corporate governance and the performance of Egyptian corporates. Moreover, a bi-causality relationship can be observed between CG and TQ.Research limitations/implications: Generalizing the obtained results would require the sample size to be extended.Practical implications: The findings should alert legislative institutions and practitioners of the need to comply with good CG practices and develop the efficiency of IC to elicit a firm’s superior performance.Originality/value: This study is one of the first attempts to investigate the causality relationships and the mediation impact of IC on the relationship between CG practices and corporate performance in the Egyptian context.
