What exactly is a National Wealth Fund? Lots of other countries have one - or something similar. In fact, there are 179 of them - holding up to $12.4 trillion in assets.   And now the Labour government is going to set one up too. So how do they work? Where does the money come from? Where does the money go? What are the opportunities? And what are the risks? And how might Rachel Reeves’ wealth fund vision play out?   Hannah and Paul are joined by top macroeconomist, finance expert, development specialist and sustainability adviser Sony Kapoor to explain all.   THE EXPERT FACTOR is the podcast for people who haven’t had enough of experts. Each week the directors of three leading and respected think tanks – Paul Johnson of the Institute for Fiscal Studies, Hannah White of the Institute for Government, and Anand Menon of UK in a Changing Europe – get together to discuss, debate and explain the big questions and themes that will shape the election – and the political landscape for years to come.    Produced by Milo Hynes and Podmasters.
