The International Transport Forum at the OECD is an intergovernmental organisation with 52 member countries. It acts as a strategic think tank for transport policy and organizes an annual summit of ministers. Our work is underpinned by economic research, statistics collection and policy analysis, often undertaken in collaboration with many of the world's leading research figures in academia, business and government. This series of Discussion Papers is intended to disseminate the International Transport Forum’s research findings rapidly among specialists in the field concerned.

Our demand analysis is complemented by ‘bottom-up’ sectoral analysis, which focus on changes in end-user demand – for example, the impact of the switch from gasoline to diesel vehicles in Europe, the effects of the rapid expansion of petrochemical capacity in Asia and the Middle East, or the growing use of natural gas and coal for power generation in Europe. Although this approach provides a valuable comparison with the main ‘top-down’ assessment, its results must be interpreted with caution. For example, will there be sufficient feedstock supply (predominantly naphtha) to sustain China’s petrochemical expansion plans? Will this expansion result in a regional petrochemical surplus, leading to the closure of less efficient plants? Global demand is predominantly driven by two primary forces, price and income. If the assumptions underlying those variables are wrong, then the output of the model will be affected. Similarly, the robustness of the historical data underpinning the model is important. Finally, substitution issues can work in many ways, leading to additional modelling complications. Prices When constructing our medium-term forecasting model, a price assumption was one of the harder concepts to incorporate. The dynamics of the oil market have changed considerably over the past five years and we are unaware of any formal price model that predicted a rise in the oil price from $25 to $90/bbl over the past four years. The seemingly robust relationship between oil stocks in the OECD and prices appeared to break down, Additional inputs such as refining capacity, spare upstream capacity, investment flows, natural gas prices and the term structure changes between spot and forward prices have all had an impact.
