Purpose: This study examines the firm's characteristics and the corporate governance factors that influence the auditor change decisions, and observes the market reaction following the announcement of such decisions. Design/methodology/approach: The relation between the firm's characteristics and the corporate governance factors with the auditor change decision is addressed using a logistic regression. The market reaction to the auditor change announcement is tested using the event study methodology. Findings: The results show that the company's size is positively related to the auditor ...

Purpose - The purpose of this study is to capture the relationship between credit risk of European commercial banks and their profitability, taking into consideration regulatory requirements under several stressed scenarios. Design/Methodology/Approach - The sample of this study consists of 12 out of 15 largest commercial banks in Europe as measured by their total assets in 2017. This study uses hypothesis testing and stress testing approaches to capture the relationship between credit risk of banks and their profitability and to determine the sufficiency of bank capital adequacy. Findings ...

Purpose – The purpose of this thesis is to determine the impact of the recent oil price decline on the GCC banking system. Design/methodology/approach – The econometric Chow model is used to test for structural breaks in the performance of selected sample GCC banks (Saudi, UAE, and Qatar banks) upon the occurrence of the recent oil price decline at the various aspects of bank performance (profitability, liquidity, credit quality, and capitalization). Findings – While Qatar banks are found to be resilient showing continuous performance over time, the Saudi and UAE banks are found to be significantly ...

Purpose: This study has two main purposes. First, Assess and compare the predictive ability of the Exponentially Weighted Moving Average EWMA, the Generalized Autoregressive Conditional Heteroscedasticity EGARCH (1, 1), the Exponential Generalized Autoregressive Conditional Heteroscedasticity EGARCH (1, 1), and the Glosten, Jagannathan, and Runkle Generalized Autoregressive Conditional heteroscedasticity GJR-GARCH. Second, Value at Risk is calculated using the Historical Simulation approach and the Extreme Value Theory. Methodology, Design and Approach: The models’ parameters are estimated from ...

Purpose -- the purpose of this thesis is to investigate employees' resistance to change in the specific case of system automation. The research attempts to deduct the managerial practices that can be implemented to overcome such resistance. Design/methodology/approach -- for data collection purposes, a quantitative questionnaire was distributed among randomly selected participants who have been through a change in software/systems during their employment period. The study's epistemology is positivism, the ontology is objectivism and the research approach is deductive. Findings -- the result ...

Purpose –The purpose of this thesis is to assess employees’ engagement in the nursing and administrative departments at Albert Haykel Hospital. Design/methodology/approach –Deductive in nature, this thesis uses a questionnaire survey to examine the extent to which the elements of engagement vary with demographic variables of the respondents as well as the existence of a significant linear relationship between them. The analysis of any variation and relationship is manipulated through the use of descriptive and inferential statistical methods. Findings –The results of this study show a variation ...

Purpose: The purpose of this thesis is to investigate the ability of EWMA, GARCH (1, 1), GARCH (p, q) and EGARCH (1, 1) to forecast volatilities of Bitcoin, Ripple, EURUSD, GBPUSD and CNYUSD. The optimal volatility model for each fiat and virtual currency is used to measure the accuracy of VaR by incorporating the volatility update into the Historical Simulation approach. Design/Methodology/Approach: In-sample returns are calculated from daily closing prices and are used in estimating the parameters of the selected models. The calculated in-sample parameters are applied to estimate and forecast ...

Purpose – This research attempts to unveil the plausible relations that may exist between internal strategic openness, perceived alignment, and engagement, as well as scrutinize how each may vary between employees of different demographic characteristics at microlevels of an organization. Design/methodology/approach – Employing a mixture of deductive and inductive reasoning approaches, this study poses six research questions and quantitatively tests twenty four hypotheses using a sample of 216 employees working in core banking functions at Bank of Beirut. Findings – The findings show that ...

Purpose: The purpose of this study is to explore the ability of EWMA, GARCH (1,1) and EGARCH (1,1) to forecast volatilities of S&P500, SSEC and MICEX, reference to two time periods in the timeframe of the Syrian war. VaR is derived using the HS approach which incorporates in its calculation the volatility of the best chosen model. The added value is the application of EVT in order to determine VaR results, which are compared and analyzed to the results of the HS approach, to define the most accurate approach. Methodology of Work: Returns of the in-sample period prices are used in estimating ...

Purpose: The purpose of this study is to empirically test the level of interdependence between three major assets: Gold, crude oil and USD index in terms of the return volatility spillover effects. This helps investors managing their portfolios and provides them with sense of direction on how to use these assets in portfolio diversification leading to a risk reduction benefits. Design/methodology/approach: Gold, oil and USD index volatilities are estimated using EGARCH (1, 1) model after detecting the stationarity and heteroskedasticity of the sample using the following diagnostic tests: Augmented ...
