Renewable generation sources still have not achieved economic validity in many countries including Korea, and require subsidies to support the transition to a low-carbon economy. An initial Feed-In Tariff (FIT) was adopted to support the deployment of renewable energy in Korea until 2011 and then was switched to the Renewable Portfolio Standard (RPS) to implement more market-oriented mechanisms. However, high volatilities in electricity prices and subsidies under the RPS scheme have weakened investment incentives. In this study we estimate how the multiple price volatilities under the RPS scheme affect the optimal investment decisions of energy storage projects, whose importance is increasing rapidly because they can mitigate the variability and uncertainty of solar and wind generation in the power system. We applied mathematical analysis based on real-option methods to estimate the optimal trigger price for investment in energy-storage projects with and without multiple price volatilities. We found that the optimal trigger price of subsidy called the Renewable Energy Certificate (REC) under multiple price volatilities is 10.5% higher than that under no price volatilities. If the volatility of the REC price gets doubled, the project requires a 26.6% higher optimal investment price to justify the investment against the increased risk. In the end, we propose an auction scheme that has the advantage of both RPS and FIT in order to minimize the financial burden of the subsidy program by eliminating subsidy volatility and find the minimum willingness-to-accept price for investors.

The Egyptian media has witnessed various changes in the ownership spectrum after the 2011 revolution. To explore this evolution, and through the Habermasian lens, this study examined ownership concentration in the 2019 media sphere in Egypt by mapping media outlets and their owners. It also investigated the relationship between this concentration and content diversity in a sample of print outlets in the first quarter of 2019. Three patterns of ownership concentration in the Egyptian media were identified: concentrated state ownership, concentrated private ownership, and not concentrated private ownership. Based on these findings, I argue that the media sphere in Egypt is dominated by a few gatekeepers, mostly the state, that influence content diversity and jeopardize the democratic public sphere in postrevolution Egypt.
