Abstract:
The success of global climate policies over the coming decades depends on the diffusion of 'green' technologies. This requires that international environmental agreements (IEAs) and trade-related intellectual property rights (TRIPs) interact productively.Using a simple and tractable model, we highlight the strategic reduction in abatement commitments on account of a hold-up effect. In anticipation of rent extraction by the innovator signatories might abate less than non-signatories turning the IEA 'brown'. Self-enforcing IEAs have fewer signatories and diffusion can reduce global abatement under TRIPs. Countries hosting patent holders extract rents from TRIPs, but may be better off without them.
