Abstract It has been demonstrated that most people have a limited understanding of atmospheric CO2 accumulation. Labeled stock-flow (SF) failure, this phenomenon has even been suggested as an explanation for weak climate policy support. Drawing on a typology of knowledge, we set out to nuance previous research by distinguishing between different types of knowledge of CO2 accumulation among the public and by exploring ways of reasoning underlying SF failure. A mixed methods approach was used and participants (N = 214) were enrolled in an open online course.

Uncertain penalties and compliance: experimental evidence

Submitted by César Salazar on 8 May 2020

We present the results of a series of economic laboratory experiments designed to study the compliance behavior of polluting firms when penalties are stochastic. The experiments consist of a regulatory environment in which university students faced emission standards and an enforcement mechanism composed of audit probabilities and penalties (conditional on detection of a violation).

Clean up your own mess: An experimental study of moral responsibility and efficiency

Submitted by Elin Lokrantz on 5 May 2020

Although market-based environmental policy instruments feature prominently in economic theory and are widely employed, they often face public resistance. We argue that such resistance may be driven by moral responsibility, where citizens prefer to tackle the environmental problems that they have caused by themselves, rather than delegating the task to others by means of a market mechanism.
