Item Restricted THE VALUE AND COST OF POLITICAL CONNECTIONS FOR FIRMS IN SAUDI ARABIA(University of Rhode Island, 2024) Alqarni, Abdulmajeed; Goto, ShingoIn the first chapter, we examine the impact of political connections on firm value during the 2017 Saudi anti-corruption purge using a difference-in-differences event study type. Politically connected firms experienced significant pre-event negative Cumulative Abnormal Returns (CARs), driven by rumors of the purge. The average CARs were insignificant on the event day, as the effects had already been anticipated and priced in. However, firms directly involved in the purge suffered sharp post-event declines in CARs, while other firms showed positive returns. The second chapter investigates the relationship between state ownership and corporate performance in Saudi Arabia. We have found a negative association between government ownership and firm performance. State-owned enterprises pay higher dividends and have a lower leverage ratio. There are no significant differences between state-owned enterprises and non-state-owned enterprises in investment spending and efficiency. Finally, government ownership in Saudi Arabia is the highest in strategically important industries such as utilities and energy.31 0Item Restricted Green alternative aggregate for cast stone products(Cranfield University, 2023-11-16) Alqarni, Abdulmajeed; Salonitis, Konstantinos; Pagone, EmanueleRapid urbanization and infrastructural growth have increased the need for construction materials, placing more stress on natural resources and raising worries about carbon emissions. Cast stone, which has its own requirements and specifications, has also contributed to these issues. This research investigates the alternatives that are suitable to replace natural aggregate in cast stone products to reduce these effects. Both alternatives for cast stone product and regular structural concrete were considered all while ensuring the technical requirements of cast stone are met by each proposed alternative. The major requirements used to determine the suitability of the alternative were Compressive strength water absorption which was satisfied by 7 out of the 13 alternatives examined based on the UKCSA standard. To rank alternatives An automatically weighted TOPSIS method was used to rank alternatives based on 4 criteria: compressive strength as a representative of quality and durability, CO2e emission and replacement intensity to determine the alternative impact on the environment and finally, the cost to represent the possible economical barrier. With the focus being on manufacturing emissions and cost. Extensive data was collected on the performance of each alternative with selected criteria. The MCDM results were used to rank alternatives based on a uniform distribution of weighs and by adding that to the combined effect of three additional 3 nonuniform distributions that incorporate almost all the scenarios (73 cases) investigated by a Decision maker.12 0
