Jason Furman reviewing  Confronting Inequality: How Societies Can Choose Inclusive Growth “On the substance, the book finds that, on average, inequality results in less sustainable growth and lower growth. Redistribution has no direct adverse impact on growth and by reducing inequality actually helps it. Structural reforms (like deregulation) generally increase growth and inequality. Fiscal austerity hurts both growth and especially inequality, with the authors suggesting that it does not generally pass a cost-benefit test because the benefits of less debt are outweighed by the cost of getting to less debt. Monetary expansion reduces inequality.“

the book presents the IMF authors work it doesn’t argue the other side but makes a case against fiscal austerity...

Economist Jason Furman makes a much better summary review than me.
