UNCTAD's Integrated Programme for Commodities (IPC) would come much closer to being realised, if the industrial and the developing countries could agree on creating the Common Fund. But the Fund remains in dispute. While the LCDs only want to discuss the details of its organisation, the...

This article utilizes a new concept of supply and demand for raw materials. It emphasizes the need for the use of long run economics rather than short run analysis in the determination of a fair price for raw commodities.

The stabilisation of GHG atmospheric concentrations at levels expected to prevent dangerous climate change has become an important, global, long-term objective. It is therefore crucial to identify a cost-effective way to achieve this objective. In this paper we use WITCH, a hybrid...

In this study, cost-effective technological options to stabilize CO2 concentrations at 550, 500, and 450 ppmv are evaluated using a world energy systems model of linear programming with a high regional resolution. This model treats technological change endogenously for wind power, photovoltaics,...

The threat of global warming calls for a major transformation of the energy system the coming century. Modeling technological change is an important factor in energy systems modeling. Technological change may be treated as induced by climate policy or as exogenous. We investigate the importance...
