This study uses an incentive-compatible experimental online supermarket to assess whether prior environmentally-friendly behaviour outside the store, and whether carbon taxes motivate sustainable consumption. Previous research suggests that past decisions may influence current decisions, for...

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 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...
