The Ricardian Approach to Budget Deficits. Robert Barro, 2017, Book Chapter, “In recent years there has been a lot of discussion about US budget deficits. Many economists and other observers have viewed these deficits as harmful to the US and world economies. The supposed harmful effects include high real interest rates, low saving, low rates of economic growth, large currentaccount deficits in the United States and other countries with large budget deficits, and either a high or low dollar (depending apparently on the time period).” (Reprint from 1989) Link
