Inventory Excess?
The nation's economic activity
remained practically flat in the first
quarter of 1 979, except in the area of
inventory spending. According to preliminary GN P data, real inventory
investment increased 45 percent over
the preceding quarter, and this information was buttressed by earl ier
monthly reports from manufacturers
and. distributors. The National
Association of Purchasing Management,
for instance, noted 'that purchasedmaterials inventories increased sharply
in March, and the percentage of
members reporting higher stocks was
the highest since last July. This raises
several questions:
1. Is the stock buildup basically
speculative in nature? As such, it could
be a sign of an ongoing inventory boom,
wh ich wi II be followed by a sharper
than expected economic slowdown.
2. Is the inventory accumulation
largely involuntary, the resultofweaker
than anticipated first-quarter sales? If
so, the undesired stocks may be signalling the beginning of a classical
inventory cycle, with this buildup to be
followed by a sharp cutback later on.
3. Is the first-quarter buildup largely
a voluntary effort to replenish stocks
after an unanticipated fourth-quarter
surge in sales? If so, current inventory
behavior does not necessarily indicate
any economic weakness, but simply
represents another stage in the series of
mini-cycles which have characterized
this four-year-old business expansion.

No speculativebuildup
Recent data do not indicate any
substantial speculative buildup, on
the basis of movements in the three
different types of factory stocks
materials and supplies, work in process,
and finished goods. During the 1974
speculative binge, manufacturers built
up very large inventories of materials
and supplies, in anticipation of higher
prices and major shortages in the future. Altogether, materials and supplies
constituted 48 percent of the entire
buildup in that year. In contrast, materials and supplies constituted only 29
percent of the inventory buildup in the
first two months of 1979. Indeed,
during the past few months, the distribution of inventories by stage of
fabrication was closest to the pattern
existing in 1978, a period characterized
by conservative inventory policies.
Some analysts suggest that the buildup
was not purely speculative, but was
related to a desire'to build up stocks in
anticipation of a lengthy Teamsters'
strike. There may have been some of
this, but it was probably minor. In fact,
a weekly Labor Department survey on
the strike's impact provided no evidence that businesses had stockpiled
materials to any significant degree in
anticipation of the strike.
The second possibility was that
business firms accumulated inventories
involuntarily, because of the weakerthan-expected pattern of final sales

This may have been true some nnes,
but the aggregate statistics show little
evidence of such a buildup. If this had
been true, manufacturers' finishedgoods inventories would have increased
sharply. However, finished goods
accounted for only 26 percent of the
total buildup in January and Februaryin contrast to the situation during the
heavy 1 974 buildup, when they
accounted for almost 30 percent of
the total increase.

Deliberate buildup
The third possibility-a
conscious desire to replenish stocks-seems to be
the most likely explanation on the basis
of available evidence. At the beginning
of 1 979, stocks were at historically low
levels relative to sales, because of the
unexpectedly rapid pace of sales during

the final quarter of 1978. Consequently:
the strong first-quarter accumulation
" did nQ more than return stock/sales
ratios to the average level maintained
throughout most of the 1 977-78 period,
when cautious management policies
kept atight leash on inventories.
Th is pattern of conservative inventory
management shows up in the ratios, no
matter whether they are calculated on a
constant-dollar or book-value basis
. (see chart). The book-value figures
should be discounted because of their
downward bias during periods of
inflation. (Under this measure, inventories are valued at a mix of current
and lower past prices; while sales are
valued at current prices only.) But the
ratios when calculated on a book-value
basis are sti II usefu I for short-term
comparisons, and for that matter, are

derivedfrom the GNPstatistics,suchas

On a constant-dollar basis, adjusted for
inflation, the very low stock/sales ratio
of fourth-quarter 1978 was matched
only by the ratio reached in fourthquarter 1972 and first-quarter 1973 -a
period of materials shortages and rapidly rising final sales. Despite the recent
increase, from 1.52in fourth-quarter
1978 to an estimated 1.55 in firstquarter 1979, the ratio still remains
in line with the average maintained
throughout most of the cautious 197778 period. And from early indications,
the same holds true for other ratios

On balance, inventories have remained
at relatively moderate levels in recent
months. This has favorable implications
for the national economy. Five of the
past six business cycles have been
characterized by an unintentional
buildup and subsequent liquidation of
stocks. But if business firms continue
their conservative inventory policies of .
the past two years, they can help ensure".
that any future softening of the economy will not degenerate into a more
severe decline.
