Stochastic frontiers of efficiency for Brazilian investment funds: a panel data analysis

In today’s competitive business environment, human resources are one of the most critical assets particularly for service-focused organizations. Consequently, employees’ morale has become invaluable for maintaining outstanding organizational performance and retaining employees. One of the most important factors which may affect employees’ satisfaction is workplace bullying from employers and colleagues at large. It is considered a negative and unethical issue which may degrade, humiliate and create a risk to a healthy working environment. Therefore, the main objective of this research is to investigate the extent to which workplace bullying may affect the organizational outcomes of a sample of five-star hotels in Egypt. Two questionnaires were distributed among the subjects of the sample; bell desk staff, kitchen stewards and head departments. The results of this research confirmed that there is a correlation between workplace bullying, employees’ morale and turnover intentions but, showed no correlation between workplace bullying and employees’ work performance.

This study focused on corporate governance and performance of selected Nigerian multinational firms from 2012 to 2016. Specifically, the study focused on the effect of board size, activism and committee activism on return on asset and firm growth rate. Secondary data collected from four multinational firms were analyzed via static panel estimation techniques. While board size and board activism exerted significant negative impact on return on asset, committee activism exerted insignificant impact. The results of the study further showed that board size and board activism exert insignificant negative impact on firm’s growth rate, while committee activism insignificantly spurs firm’s growth rate. Decisively, discoveries from this study reflect that corporate governance has significant negative impact on return on asset, but has insignificant influence on the growth rate of Nigerian multinational firms. Based on these findings, the authors recommended that corporate governance dynamics in firms world over should be reconsidered, such that it gives credence to more than just numbers of persons or meetings held, but the main reasons and deliberations in such meetings. It was also recommended that excessive increase in magnitude or frequency of meetings held by board of directors cum committee should be avoided.

The recent crisis of non-performing loans in the banking system has hit the Vietnamese economy hard. The GDP has been fallen down, while the bad debt ratio in the banking system has risen dramatically to 17.2 percent, and it takes more time to restore the economy and banking system. This research aims to define aspects that impact non-performing commercial bank loans in Vietnam. It covers the period of 2008–2017 using 200 identified banks of Ho Chi Minh City Stock Exchange and Hanoi Stock Exchange, and applies methods based on the regression of pooled ordinary least squares, fixed and random effects models, in particular, generalized least squares to confirm the stability of the regression model. The results show that non-performing loans this year will positively affect those in the next year. In addition, a raise in bank performance and credit growth also leads to the reduction in non-performing loans from banks. Regarding macroeconomic factors, higher interest rates would have a major and beneficial influence on failed loans in terms of macroeconomic dynamics, and, therefore, little effect on economic activity and inflation. Therefore, Vietnamese banking system should reduce the systematic risk and improve monitoring processes, drawing on the experience of global banks with extensive experience in risk management.
