In this episode, we discuss about why China is planning to build 3 millions of elevators in its country, how it could be a relief for its economy after the Covid crisis, and some consequence of its previous natality policies. We also discuss how companies can influence natality policies by talking about theses companies which are now covering the cost of eggs freezing for women. Finally, we try to explain what is the role for economists in the fight against climate change.
