There is
growing chatter in economics circles about the unsettling possibility that the
nation may never recover completely from the recent recession. Recessions
are generally regarded as abnormal disruptions and recoveries as inevitable
returns to normalcy — in large part because that is how the economy has behaved
for more than a century. Even after the Great Depression, growth returned to its long-term trend; it
just took a while. The bleaker
view – which remains, to be sure, the view of a distinct minority — is that the
years before the recession were abnormally good, and that while the recession
was abnormally bad, reality lies halfway in between.
The present
situation, in other words, is about as good as it gets.
A paper that
will be presented Thursday afternoon at a conference organized by the Brookings
Institution is the latest contribution to this literature.
The paper,
entitled “Disentangling the Channels of the 2007-2009 Recession,” will be
posted on the general conference Web site Thursday
afternoon.
The authors
argue that the slow pace of recovery reflects a long-term deterioration in
economic prospects. Specifically, they estimate that the trend growth rate of
gross domestic product fell by 1.2 percentage points between 1965 and 2005.
The argument is well illustrated by these graphs from a recent speech on the same theme by James Bullard, president of the Federal Reserve Bank of St. Louis. The top graph compares growth over the last decade with the long-term trend.
The bottom graph substitutes a gradually weakening trend line.

The economists who wrote the new paper, James Stock of Harvard and Mark Watson of Princeton, contend that the key reason for the faltering pace of growth is that the work force is expanding more slowly. Population growth has slowed, and so has the pace at which women are entering the labor market.
“These
demographic changes imply continued low or even declining trend growth rates in
employment, which in turn imply that future recessions will be deeper, and will
have slower recoveries, than historically has been the case.”
Indeed,
recent growth has actually outpaced their expectations.
“The current
recovery in employment is actually faster than predicted,” they write. “The
puzzle, if there is one, is why the recovery was as strong as it has been.”
This general
theory about the power of women has been propounded before, notably by the
economist Tyler Cowen in his recent book “The Great Stagnation.”
In the
current context, however, it is also deployed as a rebuttal to the many
economists who regard the slow recovery as a consequence of the unusual nature
of the recession. One such view holds that financial crises are particularly traumatic.
Another common theory holds that high levels of debt are restraining growth.
Both of these
views carry the implication that the good times will return.
Professors
Stock and Watson devote much of their paper to the argument, as they put it,
“that the same six factors which explained previous postwar recessions also
explain the 2007Q4 recession: no new ‘financial crisis’ factor is needed.”
In other
words, the good times are over, and they are not coming back.
But
curiously, the authors don’t seem convinced by their own argument, noting a bit
later in the paper that they can’t exclude the possibility that new factors
produced familiar effects. Indeed, they write, “At some level this must be so,
as the Lehman collapse was unprecedented and the ‘Lehman shock’ was new; so too
for TARP, the auto bailout, and the other extraordinary events of this
recession.”
That’s quite
a caveat, and it raises the obvious and important question of how they can be
sure that new causes have not or will not produce new effects.
The good news: They’re right or wrong, and we’ll know soon
enough
