Adaptation and International Environmental Agreements
We study the impact of collective effort in R&D in adaptation technologies, and also spillover effects on formation and size of stable international environmental agreements (IEAs). Our results suggest that it is possible to have more than one size of stable IEA. We can achieve a superior equilibrium, i.e., the grand coalition, if countries manage to keep knowledge spillovers low and arrange a minimum ratification threshold. This threshold is defined endogenously. We also shed light on the effects of two-sided spillover on global welfare and the size of stable IEAs.
I have been asked to chair the third and final section of this symposium on Pesticides in Aquatic Environments. This section will be concerned with the ways and means by which aquatic organisms degrade, or perhaps more correctly, biotransform or metabolize pesticides in their environment.
