Steve Williamson recently posted a joke of sorts: What's the difference between a New Keynesian, an Old Monetarist, and a New Monetarist? A New Keynesian thinks no assets matter, an Old Monetarist thinks that some of the assets matter, and a New Monetarist thinks all of the assets matter. While I wouldn't try it around the dinner table, what Steve seems to be referring to here is the question of money. New Keynesians don't have money in their models, Old Monetarists have some narrow aggregate of assets that qualify as M, and New Monetarists like Steve think everything is money-like .* This is a interesting way to describe their differences, but is it right?

Surprisingly enough, Milton Friedman, an old-fashioned monetarist, was an occasional exponent of the idea that all assets are to some degree money-like. I like to call this the moneyness view.

Anyone who's read this blog knows that I'm amenable to this idea. Before we can ask where do we draw the line? we need to ask how do we draw the line? . Either treat money as a set of distinct goods, or treat each good as more or less m...
