Article
This study evaluates the effect of minority management (MG) on capital structure for a sample of listed Japanese companies over three sectors. We used a dynamic panel, threshold-based model that can control for endogeneity to investigate the linkage between the speed of adjustment of leverage and MG, with the results proving that there is significa...
Article
In this study, we investigate the dynamic linkages between the real estate and stock markets in Qatar. Using monthly data over the period 2006–2020, the nonlinear model of Enders and Siklos (2001) and the linear and nonlinear Autoregressive Distributed Lag (ARDL) models, our investigation seeks to trace the channel of transmission between the two m...
Article
This study examines the impact of global COVID-19 cases and oil price shocks on the stock markets in the GCC. Using the Kalman filter to generate the unexpected oil price shocks, we find that, with the exception of Oman, the GCC markets responded to positive and negative oil price shocks before and during the pandemic, with impacts of higher magnit...
Article
This study, using linear and nonlinear Autoregressive Distributed Lag (ARDL) Models, investigates the dynamic linkages between oil prices and agricultural commodities. The results from the linear model show that barley, corn and rapeseed oil do not in the long run co-move with oil prices. When we use the nonlinear ARDL Model to overcome the symmetr...
Article
This study examines the impact of the two recent political and economic crises of March 2014 and June 2017 on the stock market dependence and volatility spillover between Qatar and the other GCC countries (Saudi Arabia, the United Arab Emirates, Bahrain, Kuwait and Oman). To this end, the Bai and Perron testing procedure for structural breaks and t...
Article
This study examines the impact of the FIFA's official announcements on Doha Stock Exchange (DSE) of Qatar with respect to the 2022 World Cup. Using the abnormal unsystematic return method of Savickas, our findings reveal that the relationship between this sports mega-event and the DSE is significant, indicating that the market is very sensitive to...

This study examines the impact of market-wide volatility on time-varying risk using the heteroscedastic market model with EGARCH (1,1) specification. Using daily sector returns from the Qatar Stock Exchange (QSE) market over the period 2007–2015, we find that in terms of systematic risk, the large sectors are as vulnerable to overall market volatil...
Article
Purpose: The risk-return relationship is one of the most widely investigated topics in finance, yet this relationship remains one of the most controversial topics. The purpose of this paper is to investigate the asymmetric volatility and the risk-return tradeoff at the sector level in the emerging stock market of Jordan. Design/methodology/approach...
Article
This study examines the impact of the FIFA's official announcements on Doha Stock Exchange (DSE) of Qatar with respect to the 2022 World Cup. Using the abnormal unsystematic volatility method of Hilliard and Savickas (2002), our empirical findings reveal that the DSE market is sensitive to FIFA's announcements about the 2022 World Cup. We find that...
Article
The central objective of this study is to investigate the effect of capital structure on corporate failure in the emerging market, in particular Jordan, using a panel data analysis sample representative of 180 Jordanian companies during the period 1990 to 2012. This paper also examines the effect of the financial crisis 2008 on Jordanian corporate...
Article
This study investigates the risk-return relationship at sector level in the emerging market of Jordan (ASE) over the period 1999-2014. The results of an unconditional test with a structural breakpoint show that the relationship is not stable, owing to the effect of the recent global financial crisis (GFC). The conditional test proposed by Pettengil...

In particular, the paper focuses on Colander’s argument in his paper “Economist...

This paper utilizes the Kalman filter approach to examine the impact of the Iraq war on the country betas of 11 equity markets in the MENA region. The Kalman filter model allows the country beta to vary over time conditional on the interaction with Iraq war dummy in the transition equation. The results show that the Iraq war has a positive impact o...
Article
This paper examines the relationship between beta and returns on the industrial portfolios in the financial market of Jordan using monthly data for the period of December 1999 to September 2008. The study shows that the unconditional relationship is rejected in this emerging market. We test the second model of Pettengill et al. (1995) conditional o...
