In this episode of The Sound of Economics, host Rebecca Christie talks about nature and markets with Bruegel’s Heather Grabbe and Estelle Cantillon, FRNS research director at the Université Libre de Bruxelles. They explore policy efforts to make protecting natural resources more of a financial priority, such as nature credits and nature shares, as well as the difficulty of setting up these kinds of systems. How can public money and private investors cooperate? How does a program like this avoid cheating, moral hazard and failure to deliver? Both government resources and investor buy-in will be necessary for habitats and biodiversity to find their way onto the world’s balance sheets.
