We analyze how the threat of a potential future regime shift affects optimal management. We use a simple general growth model to analyze four cases that involve combinations of stock collapse versus changes in system dynamics, and exogenous versus endogenous probabilities of regime shift. Prior...

For sufficiently low abatement costs many countries might undertake significant emission reductions even without any international agreement on emission reductions. We consider a situation where a coalition of countries does not cooperate on emission reductions but cooperates on the development...

[eng] Value and contracts in light of turgot [1769]. . From a reexamination of « Valeurs et monnaies », this paper evolves two the­sis. The first upholds that the natural contract theory, displayed in the beginning of « Valeurs et monnaies » by Turgot, contains the canonical model of value...

Recent research developments in common-pool resource models emphasize the importance of links with ecological systems and the presence of non-linearities, thresholds and multiple steady states. In a recent paper Kossioris et al. (2008) develop a methodology for deriving feedback Nash equilibria...

Ecological systems such as shallow lakes areusually non-linear and display discontinuitiesand hysteresis in their behaviour. Thesesystems often also provide conflicting servicesas a resource and a waste sink. This impliesthat the economic analysis of these systemsrequires to solve a non-standard...
