Biography

Hossa is a research fellow at KAPSARC. She is also currently the Think20’s (T20’s) Sherpa and is leading T20 Saudi Arabia’s secretariat. She is also the lead co-chair of T20 Saudi Arabia’s task force “sustainable energy, water and food systems.” Before joining KAPSARC, Hossa was a faculty member at the University of Wilfrid Laurier, Canada. Her research interests include developing energy and economic models to study the impact of energy and environmental policies on economies, sustainable development and wealth accounting. Her work aims to provide policymakers and practitioners with decision support tools that can help identify the challenges, opportunities, and solutions associated with moving toward sustainable energy and sustainable business practices. Her work has been published in many peer-reviewed journals. She has a Ph.D. and a master’s degree in applied operations research from the University of Waterloo, Canada, and a bachelor’s degree in business administration from King Abdulaziz University, Saudi Arabia.

Assessing Climate Mitigation Benefits of Public Support to CCS-EOR: An Economic Analysis

Assessing Climate Mitigation Benefits of Public Support to CCS-EOR: An Economic Analysis

Government support for CCS-EOR projects is sometimes contested on the grounds that the resulting increase in oil production undermines their environmental benefits. Addressing this concern requires determining the effects of implementing CCS-EOR on global CO2 emissions. This paper presents a simple approach based on a marginal reasoning consistent with economic decision-making. It produces analytical formulas that account for the effects on the global oil market of incentivizing CCS-EOR. Our results suggest that, from an economic perspective, CCS-EOR is a technology that mitigates global emissions, but the emissions reduction is less than the stored quantity of CO2. Based on our results, we discuss the size of the fiscal incentives granted by the US Inflation Reduction Act to support CCS-EOR.

Resilience of Saudi Arabia’s Economy to Oil Shocks: Effects of Economic Reforms

Resilience of Saudi Arabia’s Economy to Oil Shocks: Effects of Economic Reforms

We assess the extent to which the implementation of Saudi Vision 2030 policies enhances the Saudi economy’s resilience to oil price and production shocks, and to the productivity of tradable and non-tradable goods. We extend Blazquez et al.’s (2021) dynamic stochastic general equilibrium model to capture the country’s economic diversification policies and build a resilience index based on impulse responses to shocks.

Sectoral and Economy-Wide Effects of Domestic Energy Price Reforms in Saudi Arabia

Sectoral and Economy-Wide Effects of Domestic Energy Price Reforms in Saudi Arabia

This paper simulates the sectoral and economy-wide consequences of deregulating energy prices in Saudi Arabia. Our analysis is based on KAPSARC’s general equilibrium energy model (KEMGE), a new hybrid computable general equilibrium model (CGE). The model examines the effects of full price deregulation, starting in 2019, on economic activity and revenue in the year 2030.
