What would you say a human life is worth? According to the US government, for an American it’s about $7.2 million, compared with the global average of approximately $1.3 million. If you’re Swiss though, you’re worth a pretty penny at $9.4 million.

While these estimates might sound absurd, they're really important to understand: these kinds of figures and the models that produce them are a core part of how mainstream economics understands and shapes policy, and they have had a significant role in shaping our approach to the climate crisis. Indeed, as Adrienne and celebrated economist Ha-Joon Chang break down in today's episode, mainstream economics gets a lot wrong, and has proven strikingly ill-equipped for addressing a challenge like climate and ecological crisis, not least through its tendency to reduce complex decisions to abstracted cost-benefit analyses.

Ha-Joon Chang is an economist and Professor at SOAS University of London. Ha-Joon has been an advisor to several international organisations, and is the author of many books, most recently ‘Edible Economics’.
