Nexus between Volatility of Stocks and Macroeconomic Factors during Global Financial Crisis: Evidence from Conventional & Islamic Stocks

Purpose: The study explores the relationship between the volatility of stock return of markets (Islamic & conventional) and macroeconomic factors by using GARCH in Mean (1,1) model during global financial crisis. Design/Methodology/Approach: monthly data for the period from 04 Jan, 2005 to 31st Dec, 2015. The Islamic stock markets (Dow Jones Islamic Market Malaysia (DJIM), Dow Jones Islamic Market Indonesia (DJII) & Dow Jones world Islamic Index (DJWI)-Benchmark), Conventional stock markets (Shanghai Stock Exchange (SSE),Bombay Stock Exchange (BSE) & Pakistan Stock Exchange (PSE) and Macroeconomic factors (Inflation, Interest Rate, Oil prices and Industrial Production) are taken into consideration. Findings: The results explored that inflation rate influenced the returns of conventional stock markets than Islamic stock markets. Moreover, the volatility components for macroeconomic factors i.e. inflation, interest rate and oil prices are more volatile but larger to industrial production during global financial crisis. Implications/Originality/Value: However, the frequency of market volatility for Islamic stock market is lower than conventional stock markets that mean that the investment in Islamic stock markets seems to be safe flight than conventional stock markets during global financial crisis

A Comparison of Some Test Statistics for Multivariate Analysis of Variance Model With Non-Normal Responses

The Multivariate analysis of variance (MANOVA) is often used to model responses from more than one response variable on a single factor or a set of factors of interest. The existing statistical methods for MANOVA modelling generally assume that the set of responses, and by extension the model error term have a Gaussian distribution. However, in many real life situations, the vector of responses are not normally distributed, thereby rendering some of the existing methods inefficient, especially under small sample size situations. This study therefore, investigates, through Monte-Carlo studies, the behaviours of three of the existing techniques for performing MANOVA tests when normality assumption on the error term is violated. Two truncated test statistics for MANOVA testing on data with non-normal responses were developed from the existing test methods. The Monte-Carlo results showed that the original Roy’s test method and the two proposed truncated test statistics are relatively more efficient for MANOVA testing on data with inherent non-Gaussian responses under small sample sizes situations.

Haemovigilance as a quality indicator in transfusion medicine: Pakistan’s perspective

In transfusion medicine, the concept of haemovigilance has emerged during the last three decades. It is structured and systematic surveillance of the entire vein-to-vein transfusion chain and a powerful quality tool. Haemovigilance has become an integral component of transfusion medicine. It helps increase safety and improves quality during blood donation and blood transfusion, from the blood donor to recipient of blood and blood components. The haemovigilance can be successfully implemented and maximum benefit obtained if the data analysis and resulting conclusions are mutually shared with the shareholders. Although haemovigilance has proven to be an effective tool to influence policy development, it is is not well established in Pakistan. The government’s Safe Blood Transfusion Programme has taken key initiatives to introduce, support, and consolidate the haemovigilance system necessitating many changes, in the system, in the institutions, in attitude, and behaviour. The implementation of haemovigilance in Pakistan will require a major paradigm shift. It will be a stepwise or staged approach, starting from institutional to regional/provincial levels and ending at the national level

Transformational Leadership and Corporate Reputation: Mediation Effects of Employer Branding

The purpose of this paper is to examine the impact of transformational leadership and corporate reputation on employer branding by testing a hypothesized model. This study employed a quantitative online survey technique. The researcher distributed 350 questionnaires through purposive sampling out of which 132 questionnaires received back for data analysis. Regression analysis was selected to analyze the collected data to test the hypothesis developed from past literature. Results validate that transformational leadership has an impact on employer branding and employer branding has a direct impact on corporate reputation but correlation amid transformational leadership and business reputation goes insignificant when added employer branding showing full mediation of this variable. The present study backs the writings of business reputation that can be developed through transformational leadership and employer branding. The findings would be helpful for organizational leaders in developing strategies to create a corporate reputation
