No full textThe COVID-19 pandemic has affected our daily life brining unprecedented changes. This
outbreak has shifted many families’ life mainly the ones with children. Balancing between
working from home, being responsible for children’s care, and home-schooling, as well as
doing the housework have been very difficult. In addition, the mental health and well-being
of children are a priority to every single mother besides taking care of her own
Evaluation of sustainable strategies adoption for competitiveness within the Qatar oil and gas sector
No full textA thesis submitted in partial fulfilment of the requirements of the University of Wolverhampton for the degree of Doctor of Philosophy.With the increasing importance given to sustainable development, now-a-days countries around the world are shifting their focus and efforts to changing the previous unsustainable growth framework that has been ineffective. Qatar seems to be following the rest of the world and has decided to introduce a sustainability plan to ensure prosperity through its national vision and strategy plans. However, despite Qatar’s National Vision 2030 implementation, several organisations within the oil and gas sector still have difficulties in embedding sustainability agenda in their systems and processes. There is, also, a paucity of empirical research on the implementation of sustainability strategies within the Qatar oil and gas sector to improve competitiveness. Therefore, the aim of this research is to evaluate the Qatar oil and gas sector implementation of sustainability strategies so as to improve its competitiveness. A qualitative approach was adopted to collect and analyse data based on 24 interviewees from eight Qatar oil and gas organizations. The research started with a purposive sampling method that was later adapted to snowball. Semi-structured interview was selected as the data collection tool, and thematic analysis was chosen to acquire an in-depth knowledge of the interviews. Systematics approaches, such as the Total Interpretive Structural Modelling (TISM), Fuzzy Matrice d’Impacts Croises-Multiplication Applique an Classment (FuzzyMICMAC), maturity model and Graph Theoretic and matrix Approach (GTMA), were selected appropriately in order to achieve the research objectives. A framework and readiness tool were developed as the output of the research findings. The results of the study revealed that the Qatar oil and gas sector identified six main areas of interest to evaluate the performance of the sector and its organisations: workforce, health and safety, society, environment, climate change, and economy. Overall, the Qatar oil and gas sector is operating within or above governmental laws and regulations, which is evident in some organisations’ adapted policies and strategies. It is found that international standards and governmental regulations and laws are amongst the main drivers that fuelled for the implementation of sustainability initiatives within the sector. While strategic issues were highlighted as the main inhibitor to sustainability implementation within the sector. The findings of this research provide valuable insights that would help the Qatar oil and gas industry’s decision makers to implement sustainability initiatives to improves the sector’s competitiveness
THREE ESSAYS ON INTERNATIONAL ASSET PRICING
No full textThe common thread running through my research is to explore the asset price dynamics across countries and across asset classes. In the first chapter of this thesis, I apply Newton's law of universal gravitation to investigate the determinants of the bilateral relationships in returns. Examining the gravity effect in a large set of countries, I find that the size of economies and geographical distance are significant determinants of the contemporaneous as well as the lead-lag correlation patterns observed in stock returns across countries. In addition, decomposing stock market returns into cash-flow and discount-rate news shows that the international transmission of country specific news is more pronounced through discount-rate news, and that the size of economies and geographical distance are significant determinants for both components of returns.
In the second chapter, based on a joint work with Redouane Elkamhi and Mikhail Simutin, we propose a diversification approach that exploits the global connectedness of developed countries to gain exposure to emerging countries' overall economies rather than their shallow equity markets. In doing so, we demonstrate that developed markets still offer substantial diversification benefits beyond those available through equity indices, contrary to a large body of literature claiming that the benefits of international diversification via developed markets have dramatically declined. Our results also suggest that relying on equity indices to assess diversification benefits understates diversification gains.
The third chapter explores the potential risk of investing in global markets. Specifically, my co-author Redouane Elkamhi and I study the two widely-known speculation strategies in the FX market, carry and momentum trades, and provide a risk-based explanation for the excess returns. We construct a common factor that drives correlation across international equity markets and show that the cross-sectional variations in the average excess returns across carry and momentum portfolios can be explained by different sensitivities to our correlation factor. By using a factor constructed from the equity market to explain abnormal return in the FX market, these findings shed light on the important linkage across the two markets through equity correlations as a main instrument of the aggregate risk.Ph.D

Evaluation of challenges for sustainable transformation of Qatar oil and gas industry: A graph theoretic and matrix approach
No full textThis is an accepted manuscript of an article published by Elsevier in Energy Policy on 18/01/2022, available online at: https://doi.org/10.1016/j.enpol.2021.112766
The accepted version of the publication may differ from the final published version.Despite Qatar’s National Vision 2030 implementation, several organisations within the oil and
gas sector still have difficulties in embedding sustainability agenda in their systems and
processes. There is, also, a paucity of empirical research on the key challenges Qatar oil and
gas organisations face in embedding sustainable strategies to improve competitiveness – which
is the core raison d’être of this paper. A qualitative approach was adopted to collect and analyze
data based on 24 interviewees from eight organizations. Six key challenges hindering the
implementation of sustainability strategies. They are: stakeholders’ issues, volatility of price,
resistance to change, knowledge and awareness, initial cost and strategic issues. Furthermore,
the graph theoretic and matrix approach was applied to evaluate the challenges inhibiting the
implementation of sustainability strategies within the Qatar oil and gas industry. The results
show that strategic issues represent a greatest challenge when compared to other challenges
External drivers for embedding sustainability practices within the Qatar oil and gas industry: An institutional theory perspective
No full textThis is an accepted manuscript of an article published by British Academy of Management in BAM Conference in the Cloud Proceedings. The accepted version of the publication may differ from the final published version.With the increasing importance given to sustainability, organisations now-a-days
are implementing sustainability practice within their strategies to ensure a positive impact on
their stakeholders, society and environment. Qatar seems to be following the rest of the world
and has decided to introduce a sustainability plan to ensure prosperity through its national
vision and strategy plans that targets all of its sectors and especially the oil and gas.
Furthermore, there is a very limited research on external drivers for implementing
sustainability practices within organisations in the Qatar oil and gas, which is the core
purpose of this paper. Using institutional theory, the paper had shed the light on external
pressures exerted by different institutions on organisations in order to implement
sustainability practices. Through a systematic approach, qualitative data collection and
analysis was carried using semi-structured interviews and content analysis of professional
from the Qatar oil and gas industry to enquire about the external drivers that pushed their
organisations to implement sustainability initiatives. The findings show that organisations are
driven to implement sustainability by seven drivers, that could be grouped into three main
categories, coercive, normative and mimetic pressures. It is argued that organisations’ attempt
to conform and reduce the uncertainty regarding sustainability would depend heavily on the
type of force exerted on them. Therefore, decision makers and executives must have a better
understanding of sustainability pressures exerted on their organisation in order to ensure an
improved sustainability performance
Sustainable transformation of Qatar oil and gas industry: An organisational cultural perspective
No full textThis is the accepted manuscript of a conference paper due to be presented at Recovering from COVID: Responsible Management and Reshaping the Economy, 35th British Academy of Management Conference, the 31st August - 3rd September, Lancaster University Management School, United Kingdom.Sustainable development and sustainability are concepts that are gaining a lot of popularity recently, mainly due to the increasing concerns regarding business and the environment relationship. Following the footsteps of the world, Qatar commitment towards sustainability was confirmed with the introduction of the Qatar National Vision 2030 and different National Development Strategies, where the Qatar leadership had outlined its development goals for the next generations to incorporate the concept of sustainable development. Such decisions induce changes within the country’s local, regional and national industry sector and especially oil and gas. The pathway for a successful implementation of sustainability strategies within organisations in the sector depends heavily on the alignment of the organisational culture with such change. Therefore, this paper provides a in depth view of the cultural changes the Qatar oil and gas sector underwent to manage the adaption of sustainability initiatives. The paper adopted a qualitative approach for the data collection process, interviewing 24 professionals from eight different Qatar oil and gas organisations. A thematic analysis was carried out to analyse the results and findings shows that important cultural changes had been experienced within the sector since the organisations’ decision to implement sustainability. Four cultural changes identified to be adapted in the Qatar oil and gas sector and are: behavioural change, leadership attitude, shareholders’ attitude and inter-organisational collaboration. Sustainability is not a stand-alone issue, but a dimension of management culture. As such, sustainability-related skills will have to reach further than personal relations skills
A systematic literature review evaluating sustainable energy growth in Qatar using the PICO model
No full textThis is an Accepted Manuscript of a book chapter published by Routledge in Secondary Research Methods in the Built Environment on 11/03/2021, available online: https://www.routledge.com/Secondary-Research-Methods-in-the-Built-Environment/Manu-Akotia/p/book/9780367429874 For re-use please see publisher's terms and conditions.With the increasing importance given currently to sustainable development, countries around the world are shifting their focus and efforts to changing the previous unsustainable growth framework. Accordingly, Qatar has decided to introduce a sustainability plan to ensure prosperity through its national vision and strategy plans. In this chapter, a case example has been presented on the application of a systematic literature review according to the PICO model in built environment research based on a study of the efficiency of policies and tactics implemented by the Qatari Government, in its energy sector, pertaining to sustainability strategies. An initial literature search resulted in the identification of 1990 resources within five different databases, of which 82 met the pre-set inclusion and exclusion criteria, including date, geographic location, language, type of publications, participants, and design of studies. The findings showed that six key sustainability initiatives were noteworthy in the Qatar energy sector, which were: health and safety, environment, climate change and energy, economic performance, society, and workforce. The lack of knowledge of the scope of sustainability is a huge challenge for the organisations in the energy sector. The conclusion from this chapter was that the Qatari sustainable development policies still need great efforts to confront their shortcomings, as more holistic policies and more integrated and comprehensive strategies are required
