Mr. Market Miscalculates (2008), a collection of Grant's articles published over the preceding 10 years, elicited an appreciative review in the Financial Times.

[6] Grant is the author of Money of the Mind (1992), The Trouble with Prosperity (1996), John Adams: Party of One (2005), Mr. Speaker: The Life and Times of Thomas B. Reed, the Man Who Broke the Filibuster (2011), and The Forgotten Depression (2014) among other works.

His most recent publication is Bagehot: The Life and Times of the Greatest Victorian (2019), a biography of Walter Bagehot, the influential English banker, economic and political writer, and editor of the Economist, whose ideas about central banking informed the U.S. Federal Reserve's response to the global financial crisis of 2007–2009.

During Representative Ron Paul's 2012 U.S. presidential campaign, he named Grant as his likely candidate for Chairman of the Federal Reserve to replace Ben Bernanke whose term expired in 2014.
