The EU and the US launched negotiations on a Transatlantic Trade and Investment Partnership (TTIP) in July 2013. Among the TTIP aims, there are negotiable terms under which the EU would import more genetically modified (GM) products and change its labeling regulations on GM Organisms (GMOs)....

This paper presents an integrated economic model which is able to explicitly address both water quantity and quality. We use a welfare program to maximize social welfare subject to the economic and ecological constraints, where interactions, emissions and environmental impacts are incorporated....

We analyse the impacts of a change in consumers’ preference for Novel Protein Foods (NPFs), i.e. a lifestyle change with respect to meat consumption, and the impacts of environmental policies e.g. tradable emission permits for greenhouse gases (GHGs) or an EU ammonia (NH<Subscript>3</Subscript>) emission bound per...</subscript>

At present the volume of solid waste produced in modern consumer societies is increasing, requiring policy measures to reduce the volume of waste to be dumped or incinerated. In this article a materials balance optimisation model for the recycling of plastics is developed to analyse the impact...

We empirically test the role of membership rules and voting schemes for climate change coalitions with the STAbility of COalitions model (STACO). The model comprises twelve world regions and captures long-run effects of greenhouse gas accumulation. We apply three stability concepts that capture...

This paper analyses stability of coalitions for greenhouse gas abatement for different sharing rules applied to the gains from co-operation. We use a 12-regions model designed to examine internal and external stability of coalitions (STACO). We compare different sharing rules like, for example,...

Gum arabic is mainly produced from two Acacias that are found in the gum belt of Sub-Saharan Africa. These are Acacia senegal that produces high quality gum and Acacia seyal that produces low quality gum. In recent years the gum market structure has changed and Sudan lost its near monopoly...
