Long-Term Optimization of Egypt's Power Sector: Policy Implications
This paper presents an evaluation of energy supply strategies for Egyptâs power sector and identifies prospects to meet rising electricity demand while addressing energy security and low-carbon development issues. We apply the TIMES energy system model to examine Egyptâs energy policy goals as reflected in Egyptâs Vision 2030, and specifically: (a) targeted power generation based on renewable energy under two different scenarios; (b) targeted carbon dioxide (CO2) emissionsâ mitigation toward low-carbon society development; and (c) constraints on natural gas production for power generation. The quantitative results from the model suggest a need for diversification from predominantly natural gas to a mix of renewable and conventional energy sources in order to improve energy security, reduce dependency on fossil fuels, and reduce carbon dioxide emissions, with the level of diversification changing with different policy options. Although total energy system cost is projected to increase the effects on fossil-fuel dependency, diversity of energy supply-mix, marginal electricity generation price, and GHG mitigation indicate that it may be wise to target promotion of renewable energy for power generation and develop a low-carbon society
Big TAM in Oman: Exploring the promise of on-line banking, its adoption by customers and the challenges of banking in Oman
Information and communication technology (ICT) developments and trends in recent years have had great impact on the banking sector worldwide. In many developed and developing countries, the use of disruptive innovation technologies has accelerated change in the way banking business is conducted, consumers being swept along with such change. However, in many countries, such as Oman, there are deep routed cultural and religious factors that cause consumers to question the acceptance of such changes. Through the use of a theoretical framework built on technology acceptance frameworks and models, and empirical evidence from key market segments of the Omani banking market, the research explores the factors that influence Omani consumer acceptance of on-line banking. The findings are significant in that trust, usability and perceived quality are deemed key drivers. This is probably not unexpected, however, what is interesting is that the market profile is skewed to middle aged users, with social standing and âherdâ mentality does not affect the adoption of the technology. This, combined with the emerging mobile savvy younger generation poses an interesting challenge for the future of the banking sector in Oman and implies a need for the sector to rethink the strategic use of, and approach to, implementation of on-line banking in a way that is complementary to the cultural and ethological dimension of the market. In effect, the banking sector will need to manage the covert tension between technology driving âfast timeâ, and the Omani culture, religion and tradition demanding face to face âslow timeâ

Biofuels and land-use changes: searching for the top model
The use of agricultural-based biofuels has expanded. Discussions on how to assess green house gas (GHG) emissions from biofuel policies, specifically on (non-observed) land-use change (LUC) effects involve two main topics: (i) the limitations on the existing methodologies, and (ii) how to isolate the effects of biofuels. This paper discusses the main methodologies currently used by policy-makers to take decisions on how to quantify LUCs owing to biofuel production expansion. It is our opinion that the concerns regarding GHG emissions associated with LUCs should focus on the agricultural sector as a whole rather than concentrating on biofuel production. Actually, there are several limitations of economic models and deterministic methodologies for simulating and explaining LUCs resulting from the expansion of the agricultural sector. However, it is equally true that there are avenues of possibilities to improve models and make them more accurate and precise in order to be used for policy-making. Models available need several improvements to reach perfection. Any top model requires a concentration of interdisciplinary designers in order to replicate empirical evidence and capture correctly the agricultural sector dynamics for different countries and regions. Forgetting those limitations means that models will be used for the wrong purposes
Can biofuels be a solution to climate change? The implications of land use change-related emissions for policy
Biofuels have gained increasing attention as an alternative to fossil fuels for several reasons, one of which is their potential to reduce the greenhouse gas (GHG) emissions from the transportation sector. Recent studies have questioned the validity of claims about the potential of biofuels to reduce GHG emissions relative to the liquid fossil fuels they are replacing when emissions owing to direct (DLUC) and indirect land use changes (ILUC) that accompany biofuels are included in the life cycle GHG intensity of biofuels. Studies estimate that the GHG emissions released from ILUC could more than offset the direct GHG savings by producing biofuels and replacing liquid fossil fuels and create a âcarbon debtâ with a long payback period. The estimates of this payback period, however, vary widely across biofuels from different feedstocks and even for a single biofuel across different modelling assumptions. In the case of corn ethanol, this payback period is found to range from 15 to 200 years. We discuss the challenges in estimating the ILUC effect of a biofuel and differences across biofuels, and its sensitivity to the assumptions and policy scenarios considered by different economic models. We also discuss the implications of ILUC for designing policies that promote biofuels and seek to reduce GHG emissions. In a first-best setting, a global carbon tax is needed to set both DLUC and ILUC emissions to their optimal levels. However, it is unclear whether unilateral GHG mitigation policies, even if they penalize the ILUC-related emissions, would increase social welfare and lead to optimal emission levels. In the absence of a global carbon tax, incentivizing sustainable land use practices through certification standards, government regulations and market-based pressures may be a viable option for reducing ILUC
