This paper studies the relation between optimal dam capacity and water management under rivalry uses and externalities. We extend the hydropower generation model, based on Haddad (2011), by including the competing use of water resource, non-linear building cost of dam capacity and externalities...

Discounting has to take account of ecosystem services in consumption and production. Previous literature focuses on the first aspect and shows the importance of the relative price effect, for given growth rates of consumption and ecosystem services. This paper focuses on intermediate ecosystem...

With the gradual accession of some Central Eastern European Countries (CEECs) to the EU, international trade between EU and CEECs and the related environmental problems will definitely change because of the free trade and the mobility of production factors (labour and capital) within the EU....

Land subsidence threatens the living conditions of roughly 1.2 billion people worldwide in deltaic regions characterized by soft top soil. Economic activity in deltaic regions requires lowering the groundwater levels to keep the land sufficiently dry to maintain productivity, which, however,...

Previous work on the formation and stability of cartels has focused on the case of identical players. This assumption is very restrictive in many economic environments. This paper analyses stability of cartels in games with heterogeneous players and spillovers to non-members. I introduce a...

The concepts of food deficit, hunger, undernourishment and food security are discussed. Axioms and indices for the assessment of nutrition of individuals and groups are suggested. Furthermore a measure for food aid donor performance is developed and applied to a sample of bilateral and...
