Merryn Somerset Webb talks to Reaction editor Iain Martin about her new book Share Power: How ordinary people can change the way that capitalism works – and make money too. Who is shaping the big investment decisions globally? What should companies care about? Why don’t more shareholders realise they have individual and collective power? What can be done to fix it? This is the latest episode of the Author in Conversation show on Reaction. Merryn Somerset Webb is Editor-in-Chief of MoneyWeek, a columnist for The Financial Times and one of the world’s leading commentators on investment.
