Why have economists ignored nature for so long - and now they have discovered it, are they measuring it correctly?This episode tackles the issue of incorporating nature into economic measurements. These include whether there is still a trade-off between economic growth and the environment, what is still missing from economic measures, and how to get academics and policymakers to work together. This episode is hosted by Rory Cellan-Jones, and features expert guests Dr Matthew Agarwala and Dr Cristina Peñasco from the Bennett Institute for Public Policy, and Nicolas Treich, from the Institute for Advanced Study in Toulouse.Episode 2 transcriptFor more information about the podcast and the work of the institutes, visit our websites at www.bennettinstitute.cam.ac.uk and www.iast.fr/. Tweet us with your thoughts at @BennettInst and @IASToulouse.Audio production by Steve Hankey.Podcast editing by Annabel ManleyMore about our guests:Dr Matthew Agawala is an economist at the Bennett Institute, and project lead for their Wealth Economy project.
