Elijah and the Widow of Zarephath James Tobin wrote a paper back in 1963 called Commercial Banks as Creators of Money in which he pointed out that banks don't possess a widow's cruse . There has been a bit of a blog uproar over Tobin's paper (See Paul Krugman , Winterspeak , JKH , L. Randall Wray , Nick Rowe , Cullen Roche , Ramanan , Roger Sparks , and Steve Randy Waldman ). My two bits will hone in on the widow's cruse aspect of the debate. The phrase widow's cruse is defined as "an inexhaustible supply of something," which in turn is a reference to an obscure Bible story. Flip to I Kings 17:7–16 and there is a short passage in which the prophet Elijah asks a destitute widow to make him a loaf of bread. The Lord blesses the widow saying that the "jar of flour will not be used up and the jug of oil will not run dry until the day the Lord sends rain on the land." What Tobin was referring to in his paper is that unlike the widow and her jug of o...

At first glance, the large circular discs that circulated on the island of Yap in the South Pacific certainly seem quite odd. Too big to be easily transported, the stones are often seen in photos resting against their owner's houses. So much for velocity. Yap stones have been considered significant enough that they have become a recurring motif in monetary economics. Macroeconomics textbooks, including Baumol & Blinder , Miles & Scott ( pdf ), Stonecash/Gans/King/Mankiw , Williamson , and Taylor all have stories about Yap stone money. Why this fascination? Part of it is probably due to the profession's obsession with the categorical divide between "money" and "non-money". In dividing the universe of goods into these two bins, only a few select goods end up in the money bin. That an object so odd and unwieldy as a three meter wide stone could join slim US dollar bills and easily portable silver coins in the category of money is pleasantly counterintu...

Stephen Williamson catches a lot of flack on the net. Some is undeserved, some is deserved, but a big chunk is probably due to the fact that he and his fellow New Monetarist s have a communications problem. People don't understand what they're up to. So here's my attempt to bring Steve down to earth and explain to the world the importance of the research being done by him and his colleagues. I'll go about this by adding a bit of historical context. After a quick tour of the history of monetary thought, readers will be able to see where in the greater scheme of things the New Monetarists fit. Now Steve doesn't know much about the history of economic thought - he thinks it's unimportant. So in a way, I'm explaining not just Steve to the world, but Steve to Steve. One of the big problems in economics is how to deal with two significant but divergent streams of economic thought - monetary theory and real theory (ie. microeconomics). Put differently, there's...
