Natural Gas Prices converging in Germany


This is the abstract of one the papers that i was happy to contribute as a co-author.The paper is being presented in the 3rd International Workshop in Empirical Method in Energy Economics, Surrey, UK. The paper has been co-authored with Dr. Christian Growitsch and Marcus Stronzik from WIK GmbH, Germany.
"In 2007, Germany changed network access regulation in the natural gas sector and introduced a so-called entry-exit system. The re-regulation’s effect on competitiveness remains to be examined. We use cointegration analysis and a state space model with time-varying coefficients to study the development of natural gas spot prices in the two major trading hubs in Germany. To analyse information efficiency in more detail, the state space model is extended to an error correction model. Furthermore, we compare prices in Germany to those at the nearby Dutch TTF, which thus serves as a competitive benchmark. Overall, our results suggest a reasonable degree of price convergence between the corresponding hubs; however, allowing for time-variant adjustment processes, the price differentials are only partly explained by transportation costs. Persistent price differences indicate capacity constraints; nonetheless, market efficiency in terms of information processing has increased considerably."

Proceedings of the ICE, Energy


This article has been co-authored with Prof. Tooraj Jamasb and Hande Kiamil.The article can be found online under the above journal heading. Here too, i am sharing the abstract of the paper.
"A sustainable waste management policy is necessary to manage the growing stream of municipal solid waste in ecologically sustainable ways. While landfill has been the dominant form of waste management in the UK there is a need to comply with the EU Landfill Directive. Waste to Energy (WtE) is a viable waste management option to reduce the reliance on landfills and reap the energy benefits of waste. Although the first waste-fired power plant was built in the UK in 1885, several barriers have constrained the use of WtE. This paper assesses the policy and institutional context for the development of the technology in the UK. We discuss how public opinion and choice of technology are important factors in achieving a wider acceptance of WtE in the UK. Thus, there is a need to devise coordinated policies at the regional and local levels concerning a sustainable waste management strategy. Furthermore, making all WtE technologies eligible for renewable obligation certificates (ROCs) could support the development of the technology while also diverting waste from landfills. The absence of efficient heat delivery networks is also identified as a barrier to fulfilling the potential for WtE in the UK."
This journal actually belongs to civil engineers but some economists have managed to sneak in though. For more information about the journal, please visit this site:

Resources, Conservation and Recycling


This is one of the papers written with Prof. Tooraj Jamasb which has been accepted for publication in the journal of Resources, Conservation and Recycling. At this point, i am sharing the abstract of the paper here:
"The growing stream of municipal solid waste (MSW) requires a sustainable waste management strategy. At the same time, addressing climate change and security of energy supply concerns requires increased use of low-carbon and domestic sources of energy. This paper assesses the economic and environmental aspects of waste management options focusing on waste to energy (WtE) as a renewable resource. We discuss how WtE and recycling are compatible as waste treatment options. The paper then presents a social cost-benefit analysis of selected waste management scenarios for the UK focusing on specific waste management targets and carbon prices and compares them with coal fired electricity. The results indicate that meeting the waste management targets of the EU Directive are socially more cost -effective than the current practice. The cost effectiveness improves substantially with higher carbon prices. The findings show that WtE can be an important part of both waste management strategy and renewable energy policy although achieving the full potential of WtE requires development of heat delivery networks."
