We conduct a large-scale …eld experiment with 2,440 subjects in whichwe exogenously vary the price of contributing to the closest empiricalcounterpart of an in…nitely large public good, climate change mitigation.We …nd that the price e¤ect is robust and negative, but quantitativelyweak, with...

The literature on environmental R&D frequently studies innovation as a two-stage process, with a single R&D event leading from a conventional polluting technology to a perfectly clean backstop. We allow for uncertainty in innovation in that the new technology may turn out to generate a new...

We study the optimal R&D trajectory in a setting where new technologies are never perfect backstops in the sense that there is no perfectly clean technology that eventually solves the pollution problem once and for all. New technologies have stings attached, i.e. each emits a specific stock...

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...
