- Let me add only this synopsis of a panel discussion at last week's American
- Economic Association meetings. The title was "What Caused the Recession of
- 1991-92?". Chairing was Ray Fair; panelists were Olivier Blanchard, Robert
- Hall and Edward Prescott.
-
- Blanchard's hypothesis: The recession saw a large swing in consumption
- expenditures, far more than the 1980-82 recessions. There was also a fall
- in investment expenditures, but that was much milder than the consumption
- swing. The result of a fall in consumption is that the recovery is far
- smaller than are recoveries from investment-led recessions. (My own reading
- would be that this fits the 1975 recession as well.)
-
- Hall's hypothesis: Hall presented eight possible explanations of the
- recession, none of which he found completely satisfactory. The eight were:
- -- Price shocks, such as oil. Please note the oil price rises came
- after the onset of the recession. (Beware: Deluge of statistics may follow
- a flame on this point!)
- -- Unaticipated money supply change. "Why would Greenspan not
- announce he had reduced target growth?" asked Hall.
- -- Contractionary fiscal policy. There was no change in real
- spending.
- -- Tax rates increased. Sorry, Robert Bartley, but rates did not
- change greatly, though collections did.
- -- Technology shock. See Prescott hypothesis, below.
- -- Credit crunch. Hall argues that for this to have real effects,
- there had to be a regulatory change in this period. (My note: I would
- argue that a change in enforcement of the same regulation is equivalent to a
- change in regulations with the same enforcement procedures.)
- -- World economy. But this was growing in 1990, Hall said.
- -- Spontaneous decline in consumption, e.g., the Blanchard
- hypothesis. Hall commented that while there were negative shocks in 1990,
- there were positive shocks in 1988 that may have lengthened the fat years
- out to seven. It clearly had an effect, Hall concluded, but doubted it
- could explain the magnitude of the decline.
-
- Prescott hypothesis: There were a series of small productivity shocks that
- occurred in 1990, idiosyncratic and thus unexplainable, that were capable of
- producing the size of the recession we experienced. Gary Hansen and he
- developed a real business cycle model that, based on starting values set in
- 1987 (which they consider an appropriate base year) is capable of generating
- these types of cyclical behavior. In particular, labor productivity fell
- before the recession. Hall notes that the size of the producitivity decline
- was too small to explain the GDP changes; Prescott did not agree.
