      Web-Based User Interfaces for Mathematical Models to Support Decisions: The Fuel Distribution Network Optimizer

      Nourah Al Hosain, Jaidaa Alidrisi, Amr Alruthai, Walid Matar, Abdelrahman Muhsen, Pavithra Kumar Shetty, Lama Yaseen, Abeer AlGhamdi

      Mathematical models provide quantitative analyses that can inform policy decisions. We argue that two attributes can support models’ adoption by policymakers: an intuitive graphical interface and active engagement between modelers and policymakers.

      An Exposition of Bilinear “Implicit” Subsidy Equations

      Walid Matar

      The price-gap method is popularly applied to estimate energy subsidies, and it simply involves calculating the difference between the market and domestic prices of a good multiplied by the quantity consumed. In the case where subsidies impose foregone revenue rather…

      A Decomposition Approach to Energy Policy Analysis

      Walid Matar

      Index decomposition analysis (IDA) has been used to study energy use movements since the 1980s. Methods at that time consisted primarily of multiplying factors that ultimately yielded the aggregate quantity, such as energy use. IDA is a straightforward way for…

      Modeling the Distribution and Transshipment of Refined Oil Products

      Walid Matar

      KAPSARC has developed an optimization model to characterize the distribution of oil products after the refining stage. The model ensures that the demand for any group of refined oil products is simultaneously met while minimizing the social costs associated with…

      Real Gross Domestic Income for Saudi Arabia From 1986 to 2021

      Walid Matar

      A country’s national income is defined as the total market value of its output. The most used measure for national income is gross domestic product (GDP). One way to estimate GDP for a country is to sum its government consumption,…

      Alternative Fuels for Saudi Cement Manufacturing with Time-varying Carbon Pricing

      Walid Matar, Doaa Filali

      After cement production in Saudi Arabia surged in the first half of the 2010s due to the country’s rapid economic development, it has slowed measurably in recent years as economic growth has declined. This is shown in Figure 1, along…

      Long-run Effects of Real-time Electricity Pricing in the Saudi Power Sector

      Walid Matar

      This study explores the potential effects of real-time electricity pricing on the operations of Saudi Arabia’s power generation sector. The Kingdom currently sets fuel prices for power utilities at levels that suppress the costs of power generation. However, this analysis…

      On the Incremental Investment in Residential Energy Efficiency: A Saudi Perspective

      On the Incremental Investment in Residential Energy Efficiency: A Saudi Perspective

      Taylor & Francis Online

      This paper examines the marginal welfare gain of adopting higher energy efficiency after another efficiency measure has already been installed. For example, how does installing stringent thermal insulation influence energy efficiency investment decisions thereafter? A mathematical model that embeds a…

      Can Oil Refiners Adjust to a Greater Supply of Shale Oil?

      Walid Matar, Rami Shabaneh

      The advent of American shale oil and its prospects for continued production growth have raised concerns about whether oil refineries can handle the increasingly lighter crude oil supply. To provide a perspective on this issue, we run a global oil…

      On the Incremental Investment in Residential Energy Efficiency: A Saudi Perspective

      Walid Matar

      It has been shown in the literature that, in aggregate, actual household energy efficiency adoption is less than would be expected economically. Energy economists and policy analysts have described this phenomenon as the ‘energy efficiency gap.’ There could be myriad…

      A Look Back on Saudi Fossil Fuel Incentives in the Last Decade

      Walid Matar

      The Joint Organisations Data Initiative (JODI) and the Saudi Electricity Company (SEC) have just released energy use data for 2019. This insight provides an up-to-date estimation of how fossil fuel incentives have changed in 2019 compared with 2009.
