    The impact of the trade war between the US and China on the Sub-Saharan African contries: A CGE GTAP model approach
    (İbn Haldun Üniversitesi, Lisansüstü Eğitim Enstitüsü, 2023) Nantembelele, Fatuma Abdallah; Yılmaz, Mustafa Kemal
    This study examines the impact of the trade war between the US and China on the trade and economies of the SSA countries. Using social accounting matrix data from the GTAP database, the study employs a Computable General Equilibrium model (CGE), specifically the GTAP model, to run the simulations on the effects of the tariff changes between the US and China on the SSA regions. The results show that the trade war negatively affects both the US and China, creating opportunities through trade creation and diversion effects to the SSA countries. SSA is positively affected by the trade war in all tariff scenarios. East Africa and ROEA regions gain more than the other SSA regions. The sectorial results show that all sectors in the SSA encounter positive effects except the minerals and metal sector in East Africa and ROEA. The findings provide valuable insights for companies, consumers, and policymakers in the SSA countries. The trade war increased the ability of the companies to produce efficiently and meet the needs of consumers while maximizing their profit through the welfare allocative effects. The trade diversion from the US and China increased imports in the SSA regions, raising the availability of goods to meet customer needs. Policymakers may take measures to empower firms in the SSA to take more advantage of international trade-related activities.

    The effects of a US-China trade war on Sub-Saharan Africa: Pro-active domestic policies make the difference
    (Elsevier, 2023) Nantembelele, Fatuma Abdallah; Arı, Ali; Yılmaz, Mustafa Kemal; Yönetim Bilimleri Fakültesi, İşletme Bölümü
    This study simulates the impact of the change in trade policy between the US and China on the trade volume and economic prosperity of Sub-Saharan Africa (SSA). To do that, we employ a Computable General Equilibrium (CGE) model based on the Global Trade Analysis Project (GTAP) with different scenarios focusing on increases in tariffs. The results show that the tariff increases negatively affect the US and China in terms of trade volume and economic growth, while it leads to trade diversion and creation for the SSA. This offers valuable opportunities in improving exports and economic growth, particularly for Ethiopia, Kenya, and Nigeria. On the sectorial level, the findings imply that agriculture, food, and oil and gas sectors are positively affected in terms of export volume, while mineral, metal and service sectors are negatively impacted by the trade war.

    Towards sustainable cities: A sustainability assessment study for metropolitan cities in Turkey via a hybridized IT2F-AHP and COPRAS approach
    (Elsevier, 2022) Yılmaz, Mustafa Kemal; Kuşakcı, Ali Osman; Kuşakcı, Sümeyye; Sowe, Samba; Nantembelele, Fatuma Abdallah; Yönetim Bilimleri Fakültesi, İşletme Bölümü
    Accelerating trends of urbanization enforce the integration of sustainability principles into urban planning in a local scale to foster prosperity for the next generation of cities. This study incorporates fifty-three indicators on economic, social, environmental, and institutional dimensions to develop a Sustainable Cities Index (SCI) and assess the sustainability performance of thirty metropolitans in Turkey over 2010-2018. Turkish metropolitans constitute an appealing case study due to the rapid urbanization within the same time span. To answer how new metropolitans have been doing and whether they perform better than formerly declared metropolitans in Turkey, we propose a novel methodology with three stages that hybridizes Interval Type-2 Fuzzy Analytical Hierarchy Process (IT2F-AHP) and Complex Proportional Assessment of Alternatives (COPRAS). The former captures a high degree of uncertainty due to the subjective weight assignment by the experts, while the latter calculates aggregate scores for 30 cities. Finally, we conduct posthoc analyses to examine the significance of the urbani-zation policies in Turkey on the SCI scores. Thus, the study provides valuable insights into urbanization practices and encourages local administrations to spend more effort balancing the benefits and costs of public policies on sustainability.
