Real Options Methodology Applied to the ICT Sector: A Survey
This survey focuses on the application of real options methodology to the information and communications technology (ICT) industries. It examines the development of the methodology to areas as diverse as wireless cell site investments to dynamic pricing issues. In addition to aiding the reader in understanding the breadth of the applications, it demonstrates the importance of the topic. It provides a guide to the reader who is interested in exploring the topic in greater depth.Discounted cash flow, economic methodology, information and communications technology (ICT), investment, investment under uncertainty, options, present discounted value, real options, valuations.
Fuel subsidies versus market power : is there a countervailing second-best optimum?
Fuel subsidies distort end-use prices below cost, resulting in overconsumption and huge environmental cost. On the other hand, the mark-up over cost due to the exercise of market power results in the social loss of consumer surplus. We open a new line of inquiry into the potential for a market-based solution from these two countervailing forces: can the two offsetting distortions conceivably achieve a second- best optimum? Relying on dynamic panel techniques and gasoline market data for 68 developing countries, we uncover an excessive second-best subsidy offset to market power mark-up on the order of 4.5. Our results indicate that the potential for policy failure strongly exceeds the potential for market failure in our model, and gasoline prices across our sample may not be aligned with vigorous anti-climate change policy
Reducing energy subsidies in China, India and Russia : dilemmas for decision makers
This article examines and compares efforts to reduce energy subsidies in China, India and Russia. Despite dissimilarities in forms of governance, these three states have followed surprisingly similar patterns in reducing energy subsidies, characterised by two steps forward, one step back. Non-democratic governments and energy importers might be expected to be more likely to halt subsidies. In fact, the degree of democracy and status as net energy exporters or importers does not seem to significantly affect these countriesâ capacity to reduce subsidies, as far as can be judged from the data in this article. Politicians in all three fear that taking unpopular decisions may provoke social unrest.Publisher PDFPeer reviewe
Oil Security Short- and Long-Term Policies
Increasing oil security represents one of the most important policy actions, especially within IEA countries. Short and long term mechanisms could help such goal. On the short term side, revision of IEA emergency response oil stock system has been discussed. The attention is mainly focused on three issues: the high costs of stock management for private industries, the possible use of strategic reserves to smooth price when no high supply disruption has taken, the extension of IEA emergency system to non-OECD countries. The main actions specifically proposed by the European Commission are: an harmonisation of national storage systems, with the institution of public and private agency, a wider co-ordinated use of security stocks, and an increase in the physical amount of oil stocks. Long term measures for enhancing oil supply security can be seen on the demand-side and the supply-side. Main demand-side policies could be the following: energy saving and efficiency, investments in research and technology, and reduction of oil price inelasticity especially for transport sector. Main supply-side policies can be summarized into co-operation and institutional promotion for supply diversification of suppliers/routes. Main factors that could affect described policies could be the liberalization of international trade even in the energy sector and the increasing role of oil demand from developing countries.Oil, Security, Energy

The boomerang returns? Accounting for the impact of uncertainties on the dynamics of remanufacturing systems
Recent years have witnessed companies abandon traditional open-loop supply chain structures in favour of closed-loop variants, in a bid to mitigate environmental impacts and exploit economic opportunities. Central to the closed-loop paradigm is remanufacturing: the restoration of used products to useful life. While this operational model has huge potential to extend product life-cycles, the collection and recovery processes diminish the effectiveness of existing control mechanisms for open-loop systems. We systematically review the literature in the field of closed-loop supply chain dynamics, which explores the time-varying interactions of material and information flows in the different elements of remanufacturing supply chains. We supplement this with further reviews of what we call the three âpillarsâ of such systems, i.e. forecasting, collection, and inventory and production control. This provides us with an interdisciplinary lens to investigate how a âboomerangâ effect (i.e. sale, consumption, and return processes) impacts on the behaviour of the closed-loop system and to understand how it can be controlled. To facilitate this, we contrast closed-loop supply chain dynamics research to the well-developed research in each pillar; explore how different disciplines have accommodated the supply, process, demand, and control uncertainties; and provide insights for future research on the dynamics of remanufacturing systems

Cointegration and US Regional gasoline prices: Testing market efficiency from the stationarity of price proportions
It is well known that oil price shocks are a major concern to the health of the global economy. Unstable oil prices have a significant negative impact on consumer confidence and business decision making. As a result economic recovery may be longer and more complicated. Controlling the global oil price may not be possible, but a main concern of this research relates to energy market efficiency and as to whether relative price differences respond in an appropriate way across the region of one country. Here, the different geographic areas of a country are analysed to see whether they belong to the same market and result in the relative prices being stationary. The gasoline market in different regions of the US is analyzed. It is believed that if the gasoline market is sufficiently active in the US, then as a result of arbitrage, long-run gasoline prices by region should follow each other. In an efficient market, a price shock in one region would be reflected in all other prices. This proposition is tested in an effective manner by a barrage of stationarity tests. This is pertinent as such tests have been applied in antitrust cases in Italy and the Netherlands to determine whether there might be market imperfections or in association with more heuristic information, possible collusion
