 SUMMARY
t The evidence reported in this study suggests that the U. S. lumber and wood products
p industry is highly sensitive to changes in money market conditions. The time period covered by
i this study (1952-70) includes most of the post World War II years, and most important, the
period following the Federal Reserve-Treasury accord of 1951 which activated monetary policy.
The generally accepted theoretical hypothesis that monetary policy has an unequal impact
on economic activity was tested. Employing ordinary least squares and regressing the respective
lumber industry economic indicator on a monetary policy proxy, i.e., interest rates on new issues
A of 3—month treasury bills, it was found that an inverse relationship exists between activities in this
‘ 1 industry and monetary conditions.
E The extent of the industry response was also calculated and the nature of its cyclical
. ` movements was described. Although the exact magnitude of the industry response varied,
depending on the specific indicator, it was observed that in all cases the apparent response
g · outweighed manyfolds similar reactions reported in the rest of the economy. This general
I tendency was especially magnified during periods of economic contraction.
E Assuming the cyclical variations noted in the rest of the economy as the "ideal" response, it
‘ was concluded that the impact of monetary policy on the U. S. lumber and wood products
i I industry appears to be excessive. Thus, this study supports the general notion that monetary
Y actions instigated by the Federal Reserve authorities have an uneven distributive effect on
A f economic activity.
