| Summary/Abstract |
The present paper focuses on medium-term effects of alternative windfall management strategies for a resource abundant country where the resource revenues are expected to last over a prolonged period. In particular, the trade-off between spending and saving is analyzed within the framework of a recursive dynamic computable general equilibrium model. The model is further validated against historical data available for 2001-2010. The total factor productivity is calculated endogenously in the model based on a function that reflects the changes in factor productivity.
The results suggest that saving oil revenues, whether in an oil fund or through physical investment in domestic sectors, leads to a higher economic growth. However, physical investment is superior in the short to medium term based on the resultant GDP while creating an oil fund might be more beneficial in the post oil era.

| Summary/Abstract |
In the natural gas transmission network, from supply points to demand nods there are various technological options that include processing, transportation, conversion and gas distribution. Comprehensive analysis of natural gas network requires evaluation of different chains of gas flow through various levels based on economical and environmental criteria subject to technical and operational constraints such as feasibility, operability and reliability of different alternatives. To aid decision-making process in the sector of natural gas, a generic optimization-based model has been developed for assessing long term energy issues related to planning and design of natural gas supply systems. The model is capable of identifying optimal investment strategies and build up of new capacities of an integrated gas supply system. Evaluation of the potential of energy conservation and hydrogen production in transmission network are also investigated by three energy recovery technologies: turbo expander, ORC and electrolyzer. The model has then been applied in studying the development of Iranian natural gas network. The results indicate the utilization of produced hydrogen by electrolyzer has considerable impact on minimizing the total cost. The total produced hydrogen of the case study is 1337 million kg, in the period 2011-30.

| Summary/Abstract |
The paper presents further experiments with an extended version of a comprehensive model for assessment of energy technologies and research and development (R&D) planning to evaluate the impact of innovation programs on development of Iranian electricity-supply system. This analytical instrument is a model of energy R&D resource allocation with an explicit perspective of developing countries which has been linked to a bottom-up energy-systems model. Three emerging electricity generation technologies of solar PV, wind turbine and gas fuel cell are considered in the model and the impact of innovation programs on cost-reducing innovation for them is examined. The main results provided by the modeling approach include optimal allocation of R&D resources, induced capacity expansion policies to guarantee the effectiveness of R&D activities, competitive cost of emerging technologies, impact of innovation programs on optimal structure of electricity-supply system and benefits of innovation programs in the long-run.
