Quantitative models for climate policy modeling differ in the production structure used and in the sizes of the elasticities of substitution. The empirical foundation for both is generally lacking. This paper estimates the parameters of two-level CES production functions with capital, labour and...

Do the sovereign wealth funds of Kazakhstan and Azerbaijan promote the sustainable use of government oil revenues? We review the operational rules and performance of the two funds and compare them to Norway’s Government Pension Fund Global. The key challenges are to stabilize government...

To date, mineral resources are only mined on land but projected increases in demand have brought the exploration and exploitation of marine mineral resources back into focus. The Atlantis II Deep, located in the central Red Sea between Saudi Arabia and Sudan, is one of the largest marine sulfide...

This paper presents a Computable General Equilibrium (CGE) model for the analysis of environmental policies towards mining activities, and shows for the case of South Africa how it can be implemented numerically. The CGE model belongs to the class of static, trade-focussed models along the lines...

In the presence of rising carbon concentrations more attention should be given to the role of the oceans as a sink for atmospheric carbon. We do so by setting up a simple dynamic global carbon cycle model with two reservoirs containing atmosphere and two ocean layers. The net flux between these...

Genetic resources are living organisms that contain genetic information which is of importance for biotechnological research and development. Facing an accelerated worldwide loss in species diversity, the question is whether commercial trade with genetic resources can generate sufficient...

This study attempts a numerical simulation of potential CCS (carbon dioxide capture and storage) use by using a modified version of the DICE (Dynamic Integrated model on Climate and Economy) model (Nordhaus, 1994; Nordhaus and Boyer, 2000). In DICE, CO2 emissions are controlled to the extent in...

Large-scale agricultural land acquisitions might entail substantial welfare implications for the affected rural population. Whether the impacts are indeed as devastating as the popular notion of "land grabs" would suggest depends on a number of factors, including the size of compensation...

The recent empirical literature on economic sustainability of certified export crops shows that certification standards that enhance yields are important for improving farm revenues and farmer welfare. However, limited evidence exists on the impact of organic certification on the adoption of...

We estimate the impact of climate change on agricultural production in a panel of 127 countries from 1961 to 2002. In contrast to the existing literature we account for cross-sectional dependence and technology heterogeneity. We find no significant impact of climate change on agricultural...
