Big challenges lie ahead for our society: increased automation of work, and the threat of catastrophic climate change. But so, too, are the huge possibilities presented by new technology and better ways of organising our economy in the wake of neoliberalism's failure. With the election of Jeremy Corbyn as Labour leader, and the extraordinary turnaround in Labour's fortunes in the 2017 election, the possibility has opened up to build an economy in Britain that is radically fairer, radically more democratic, and radically more sustainable. But we need ideas and strategies on how to get there. Economics for the Many, edited and introduced by Shadow Chancellor of the Exchequer, John McDonnell, features contributions from the participants in McDonnell's New Economics conferences, including Faiza Shaheen, Barry Gardiner, Prem Sikka, Ann Pettifor, Paul Mason, Rebecca Long-Bailey and covers topics from housing, public ownership and fairer international trading systems to industrial policy for the 21st century and how to tackle tax avoidance and regional imbalances. Together, the essays in this volume lay out the vision for a new economics; one that works for the many, not the few.
