MONEY

An economic expert chronicles the evolution of money.

Goldstein, co-host of NPR’s podcast Planet Money, offers a brisk, brightly told history of money, ranging from lumps of metal used in ancient Greek city-states to invisible bitcoin traded online. Money, the author argues convincingly, is “a made-up thing, a shared fiction.” He continues, “a pretty good working definition of money is: it’s the thing you pay taxes with. In a world where different things are competing to be money—bills of exchange, silver and gold coins, notes from private banks—the thing the government accepts for taxes is going to win.” Besides tracing different forms that money has taken, Goldstein introduces a roster of quirky individuals who influenced monetary policy: among them, 17th-century Scotsman John Law, an inveterate gambler cognizant of the probability theory put forth by the “weirdo genius” Blaise Pascal and who powerfully shaped the French economy; Nicholas Biddle, president of America’s first central bank (at a time when the U.S. had 8,370 different kinds of paper money), who drew Andrew Jackson’s ire; Yale economist Irving Fisher, who redefined the dollar “as a fixed basket of stuff”; and Bruce Bent, inventor of the money-market fund. Goldstein deftly clarifies economic concepts, distinguishing, for example, the real economy (“the carpenter who builds your house”) from finance (“the banker who lends you money to buy the house”). Finance, he explains, “matches people who are willing to give up money now for the possibility of more money later with people who need money now and are willing to pay back more money later. Finance moves money around in time.” The author also explains the underpinnings of the 2008 financial crisis, the consequences of the adoption of the euro, and the possibilities of money in the future: the disappearance of cash, for one, and the end of banks.
