In the August 15 edition of the Financial Times, Clive Crook wrote
an op-ed piece urging the Fed to target nominal GDP growth. This is not the
worst Fed "mandate" that has been recommended. But it is not enough to recommend
a mandate or a target to this Fed. You also have to explain to it how to
maximize the probability of actually achieving its mandate. Targeting a fed
funds rate won't do the trick, especially under current circumstances. I would
suggest that if the Fed were to accept Mr. Cook's recommendation of it targeting
nominal GDP growth, the Fed should choose as an intermediate target growth
in the sum of Federal Reserve, commercial bank, S&L and credit union credit.
Chart 1 shows that the correlation between the year-over-year percent change
in this credit aggregate and the year-over-year percent change in nominal GDP
is 0.61 from Q1:1954 through Q4:2007.
In 2008, there was a significant divergence between the growth in this credit
aggregate and the growth in nominal GDP. You may recall that in 2008, the over-the-counter
money and capital markets froze up. Businesses, fearing the onset of another
depression and with the commercial paper market shut down, tapped their back-up
lines of credit at commercial banks quite heavily. The Fed through open the
discount window and created new lending facilities to nondepository financial
institutions that were desperate for liquidity with the interbank loan market
frozen. Thus, this credit aggregate soared. But entities were borrowing not
to spend, but rather to be as liquid as possible. Thus, although the sum of
Fed, bank, S&L and credit union credit soared in 2008, growth in aggregate
spending, as represented by nominal GDP, plunged. Even including this unusual
2008 episode, the correlation between growth in this credit aggregate and growth
in nominal GDP remained relatively high at 0.56 (see Chart 2).
I would leave it to the Fed's crack econometric staff to determine how fast
the sum of Federal Reserve, commercial bank, S&L and credit union credit
should grow in order to hit a nominal GDP growth target. But this is how the
Fed could do it. Scrap fed funds rate targeting. Rather, increase or decrease
the Fed's balance sheet such that the sum of Fed, commercial bank, S&L
and credit union credit grows at the rate that the Fed's econometricians believe
is consistent with the Fed's nominal GDP target growth rate.

the prestigious 2006 Lawrence R. Klein Award for having the most accurate economic
forecast among the Blue Chip survey participants for the years 2002 through
2005. The accuracy of Paul's 2008 economic forecast was ranked in the top five
of The Wall Street Journal survey panel of economists. In January 2009, The
Wall Street Journal and Forbes cited Paul as one of the few who identified
early on the formation of the housing bubble and foresaw the economic and financial
market havoc that would ensue after the bubble inevitably burst. Through written
commentaries containing his straightforward and often nonconsensus analysis
of economic and financial market issues, Paul has developed a loyal following
in the financial community. The Northern's economic website was listed as one
of the top ten most interesting by The Wall Street Journal. Paul is the co-author
